BACKGROUND: Sleep is influenced by the environments that we experience while awake and while asleep. Neighborhood walkability has been linked with chronic disease and lifestyle factors, such as physical activity; however, evidence for the association between walkability and sleep is mixed. Extant studies assign walkability based on residential addresses, which does not account for mobility. We examined the association between walkability and sleep in the Nurses Health Study 3 (NHS3) Mobile Health Substudy (MHS). METHODS: From 2018 to 2020, individuals in the United States-based NHS3 prospective cohort participated in the MHS, in which minute-level global positioning systems (GPS) data and objective sleep duration and efficiency measures were collected via a custom smartphone application and Fitbit, respectively, for four 7-day periods across a year to capture seasonal variability. Census tract walkability was calculated by summing z-scores of population density (2015-2019 American Community Survey), business density (2018 Infogroup), and intersection density (2018 TIGER/Line road shapefiles). We ran generalized additive mixed models with penalized splines to estimate the association between walkability and sleep, adjusting for individual-level covariates as well as GPS-based exposure to environmental and contextual factors. RESULTS: The average main sleep period duration was 7.9 hours and the mean sleep efficiency was 93%. For both sleep duration and sleep efficiency, we did not observe an association with daily average walkability exposure. CONCLUSION: In this study of women across the United States, we found that daily GPS-based neighborhood walkability exposure during wake time was not associated with objective wearable-derived sleep duration or sleep efficiency.

Background: Social support is a crucial factor influencing the sustainability of physical activity (PA). This proof-of-concept study presents the development of a Social Physical Activity Index for Area (SPAIFA) an indicator reflecting opportunities for individuals to actively participate as part of a group within which opportunities for social interaction can be developed. Methods: Six government councils in the state of New South Wales, Australia, were selected encompassing 174 suburbs. Using 2 search engines' map tools, we identified PA venues for each suburb (eg, park, studios, etc). To enumerate activities per suburb, we used (1) venue websites, (2) New South Wales Office of Sport website, (3) national websites of grassroots PA for nonorganized activity (eg, parkrun, meetup, etc), and (4) social media. The database was linked to the suburb demographic profile, the area disadvantage score, walkability and open space scores, and the proportion of insufficiently active residents. Spatial analysis techniques were used to identify SPAIFA clusters. Results: SPAIFA councils' average was 9.9 activities per 10,000 people (ranging from 6.6/10,000 to 16.2/10,000). SPAIFA-Old (ie, activities specific to older adults) varied significantly (ranging from 11.7/10,000 to 0.8/10,000 seniors). Disadvantaged areas and a high proportion of insufficiently active residents were associated with being classified as low SPAIFA (P <.01). Three clusters of low SPAIFA were identified, and 17 high-risk areas where low SPAIFA was compounded by poor environmental support. Conclusions: SPAIFA can be used by councils and policymakers as an indicator for monitoring and intervening in areas where natural and/or urban design is not conducive for PA. [ABSTRACT FROM AUTHOR]

Background: Active school transportation (AST) is an important source of physical activity for children and a potentially important climate change mitigation strategy. However, few studies have examined factors associated with AST in the context of the COVID-19 pandemic. Methods: We used baseline data from a longitudinal survey to investigate correlates of AST during the second wave of COVID-19 (December 2020). We collected survey data from 2291 parents of 7- to 12-year-olds across Canada and linked this information with data on neighborhood walkability and weather from national databases. We assessed potential correlates representing multiple levels of influence of the social–ecological model. We used gender-stratified binary logistic regression models to determine the correlates of children's travel mode to/from school (dichotomized as active vs motorized), while controlling for household income. We examined the correlates of travel mode for both the morning and afternoon trips. Results: Consistent correlates of AST among Canadian children during the COVID-19 pandemic included greater independent mobility, warmer outdoor temperature, having a parent who actively commuted to work or school, living in a household owning fewer vehicles, and living in a more walkable neighborhood. These findings were largely consistent between boys and girls and between morning and afternoon school trips. Conclusions: Policymakers, urban planners, and public health workers aiming to promote AST should focus on these correlates while ensuring that neighborhoods are safe for children. Future research should monitor the prevalence and correlates of AST as COVID-19 restrictions are removed. [ABSTRACT FROM AUTHOR]

This study aimed to examine the relationship between Walk Score index with walking to commuting, moderate-to-vigorous physical activity, and screen time in older adults. Georeferenced addresses were entered into the Walk Score platform. Walking to commute and moderate-to-vigorous physical activity were assessed using the International Physical Activity Questionnaire and categorized according to the World Health Organization recommendations. Screen time was analyzed through self-reported time watching television/being on the computer. We used binary logistic regression to estimate the association between variables. Older adults who lived in places with higher Walk Score had a higher prevalence of walking to commuting (odds ratio = 1.73; 95% confidence interval [1.18, 2.55]) and engaging in moderate-to-vigorous physical activity (odds ratio = 1.76; 95% confidence interval [1.05, 2.98]). A relationship also was observed between higher Walk Score and more time in screen time (odds ratio = 1.67; 95% confidence interval [1.19, 2.34]). The results showed that residing in a more walkable neighborhood increased the chances of the older adults spending 3 hr or more in front of a screen. [ABSTRACT FROM AUTHOR]

BACKGROUND: Active commuting to school can be a meaningful contributor to overall physical activity in children. To inform better micro-level urban design near schools that can support active commuting to school, there is a need for measures that capture these elements. This paper describes the adaptation of an observational instrument for use in assessing micro-scale environments around urban elementary schools in the United States. METHODS: The Micro-scale Audit of Pedestrian Streetscapes for Safe Routes to School (MAPS-SRTS) was developed from existing audit instruments not designed for school travel environments and modifications for the MAPS-SRTS instrument include the structure of the audit tool sections, the content, the observation route, and addition of new subscales. Subscales were analyzed for inter-rater reliability in a sample of 36 schools in Austin, TX. To assess reliability for each subscale, one-way random effects single-measure intraclass correlation coefficients (ICC) were used. RESULTS: Compared to the 30 original subscales, the adapted MAPS-SRTS included 26 (86.6%) subscales with revised scoring algorithms. Most MAPS-SRTS subscales had acceptable inter-rater reliability, with an ICC of 0.97 for the revised audit tool. CONCLUSIONS: The MAPS-SRTS audit tool is a reliable instrument for measuring the school travel environment for research and evaluation purposes, such as assessing human-scale determinants of active commuting to school behavior and documenting built environment changes from infrastructure interventions.

BACKGROUND: Individual adverse social determinants of health are associated with increased risk of diabetes in pregnancy, but the relative influence of neighborhood or community-level social determinants of health is unknown. OBJECTIVE: This study aimed to determine whether living in neighborhoods with greater socioeconomic disadvantage, food deserts, or less walkability was associated with having pregestational diabetes and developing gestational diabetes. STUDY DESIGN: We conducted a secondary analysis of the prospective Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-To-Be. Home addresses in the first trimester were geocoded at the census tract level. The exposures (modeled separately) were the following 3 neighborhood-level measures of adverse social determinants of health: (1) socioeconomic disadvantage, defined by the Area Deprivation Index and measured in tertiles from the lowest tertile (ie, least disadvantage [T1]) to the highest (ie, most disadvantage [T3]); (2) food desert, defined by the United States Department of Agriculture Food Access Research Atlas (yes/no by low income and low access criteria); and (3) less walkability, defined by the Environmental Protection Agency National Walkability Index (most walkable score [15.26-20.0] vs less walkable score [

Street view imagery (SVI), an emerging geospatial dataset, is useful for evaluating active transportation infrastructure, but it faces potential biases from its vehicle-based capture method, diverging from pedestrians' and cyclists' perspectives. Existing literature lacks both an examination of these biases and a solution. This study identifies and quantifies these biases by comparing conventional SVI with views from the road shoulder/sidewalk. To mitigate such perspective biases, we introduce a novel framework with generative adversarial network (GAN)-based image generation models (Pix2Pix and CycleGAN), an image regression model (ResNet-50), and a tabular model (LightGBM). Experiments assessed model effectiveness in translating car-centric views to those from pedestrian and cyclist perspectives. Results show significant differences in semantic indicators (e.g. green view index) between road center and road shoulder/sidewalk SVI, with low Pearson's correlation coefficients r (0.35–0.55 for road shoulders and 0.45–0.47 for sidewalks) indicating bias. The framework succeeded in creating realistic images and aligning pixel ratios between perspectives, achieving strong correlation coefficients (0.81 for road shoulders and 0.83 for sidewalks), thus reducing bias. This work contributes by providing a scalable and model-agnostic approach to produce accurate SVIs for urban planning and sustainability, setting a foundation for improving bikeability and walkability assessments and promoting active transportation.

A city can be characterised as a measurable pattern that comprises streets surrounded by block patterns. These street patterns are largely responsible for connectivity and accessibility, which enable people to move and interact. The study compares four samples in a case study in Baghdad, Iraq. The assets of Baghdad today belong to its historical period as its prevailing organic zigzagged network pattern determine its character. However, urban areas outside the historical zone are constructed according to modern schemes and a modernist ideology. This paper tests the connectivity and accessibility of the street network for four selected neighbourhoods. To achieve this, five indicators were applied, namely: intersection density Id, street density Sd, link to node ratio LNR, internal node connectivity INC and external point connectivity EPC. Following that, a correlation for each street parameter within the selected regions was analysed to identify the main characteristics of each variable in each area. Besides connectivity and accessibility, the paper's aim is to characterise the historical neighbourhood of Baghdad by comparing it with other chosen areas. This study applies two stages to its case study; the first reviews traditional urban pattern and compares this to the other three examples. The second stage includes the selection of three different samples within the same city, where every sample has several common variables. Adopting a quantitative method, the outcomes revealed variation across the characteristics and parameters of the street pattern within the four chosen neighbourhoods. This finding offer a precise platform and key plan for future urban design strategies and planning methods. The research concluded that a greater understanding of street patterns and parameters could help to improve the built environment and the transformation processes of the urban form, particularly when considering walkability, connectivity, accessibility, and sustainability.

Assessing street walkability is a critical agenda in urban planning and multidisciplinary research, as it facilitates public health, community cohesion, and urban sustainability. Existing evaluation systems primarily focus on objective measurements, often neglecting subjective assessments and the diverse walking needs influenced by different urban spatial elements. This study addresses these gaps by constructing a comprehensive evaluation framework that integrates both subjective and objective dimensions, combining three neighbourhood indicators: Macro-Scale Index, Micro-Scale Index, and Street Walking Preferences Index. A normalization weighting method synthesizes these indicators into a comprehensive index. We applied this framework to assess the street environment within Beijing's Fifth Ring Road. The empirical results demonstrate that: (1) The framework reliably reflects the distribution of walkability. (2) The three indicators show both similarities and differences, underscoring the need to consider the distinct roles of community and street-level elements and the interaction between subjective and objective dimensions. (3) In high-density cities with ring-road development patterns, the Macro-Scale Index closely aligns with the Comprehensive Index, demonstrating its accuracy in reflecting walkability. The proposed framework and findings offer new insights for street walkability research and theoretical support for developing more inclusive, sustainable and walkable cities. [ABSTRACT FROM AUTHOR]

With the growing evidence that connects urban environments with public health outcomes, the role of urban planning has become increasingly critical in addressing public health challenges. Cardiovascular diseases (CVDs) are the leading cause of mortality in urban areas and worldwide and are impacted by characteristics of the built environment, such as walkability and nature exposure. In this literature view, we explore the influence of the physical built environment, specifically green spaces and walkability, on cardiovascular health. Results from prior studies show a clear reduction in cardiovascular disease-related risk factors, morbidity, and mortality in neighborhoods that integrate green spaces and/or walkability. Cumulative evidence suggests that urban environments that integrate green spaces (such as parks) and walkability (eg, safe sidewalks) can significantly improve cardiovascular health. Urban planning policies and strategies that prioritize the integration of green infrastructure and walkable designs can contribute to improving cardiovascular health in urban residents while also enhancing the overall well-being and quality of life.

Saudi Arabian cities have rapidly expanded their urban areas, especially their city centers, over the last four decades. This growth has led to increased vehicular usage. As a result, the daily walking experience for residents has been adversely affected. Walkability has several positive effects on people's health and the urban environment. It serves as a means of transportation and helps create a sense of place. This enhances the legibility of urban structures and deepens emotional bonds with the city. This study uses the medium-sized Saudi Arabian city of Onaizah as a case study. It explores the feasibility of creating urban walking corridors to encourage more walking. According to Saudi Arabia's Vision 2030, sustainable urban development and improved quality of life are key priorities. The study addresses walkability as a way to enhance the urban landscape of the city center. Geographic Information Systems (GISs) were used to analyze data and generate urban corridors in the city center. The results indicate that walking in Onaizah can be improved through three urban corridors. These corridors measure 1335 m, 1624 m, and 1937 m, respectively. They represent urban, commercial, and heritage corridors. This provides planners and decision makers an opportunity to prioritize pedestrian connectivity and improve the physical environment. Such efforts contribute to sustainable urban development. Various criteria-analysis methods were employed to assess the factors that led to the conclusion of these urban corridors. This includes evaluations of land use, transportation, and environmental considerations. The study aligns with Saudi Arabia's Vision 2030 by promoting walking and enhancing overall walkability. It also aims to create a sustainable and livable urban environment for the community in Onaizah. [ABSTRACT FROM AUTHOR]

Promoting sustainable mobility and planning walkable school zones is a pressing priority, as it involves the movement of Vulnerable Road Users (VRUs), such as children aged 5–19, along with adult companions, parents, and school staff or faculty. If these children have a safe walking experience today, they will grow up to become ambassadors of sustainable mobility. In this study, several school zone areas were considered in the capital city of India, Delhi. To conduct a comprehensive walkability analysis, three distinct methods were employed: a stakeholder survey, an evaluation of existing walkable corridors, and a microscopic simulation using the Social Force Model (SFM). The limited focus on school zone safety issues in developing nations presents a case for studying the specific concerns of the school zone pedestrians, aiming to assess the magnitude of the problem, provide design centric solutions, and pick an efficient solution for implementation. The results highlight the parameters influencing pedestrian safety in school zones and their effect on pedestrian attributes. This research work can be replicated for school zone safety assessments across the world. This study will benefit the policymakers, urban planners, local government agencies, and traffic management professionals by assisting them in evaluating the walkability of school zones and promoting sustainable mobility choices.

Background: Urban neighborhood environments play an important role in facilitating or hindering residents to engage in active mobility and social participation. However, while there is much quantitative research, in-depth knowledge that contextualizes residents' subjective perceptions of barriers and facilitators of active mobility and social participation is still insufficient. Therefore, a qualitative approach was used to collect subjectively perceived barriers and facilitators of active mobility and social participation of residents from different neighborhoods with objectively determined high vs. low walkability. Furthermore, to better understand (non) concordance of objective environmental characterizations and actual levels of behavior, low and high walkability neighborhood-specific barriers, proposed improvements, and particularities that determine (non) engagement in active mobility and social participation were explored. Methods: Three focus groups (N = 6, N = 6, and N = 5) with 17 participants (7 women, 10 men) aged 21–64 (mean age 43.4 ± 14,6 years) were conducted utilizing a pre-structured interview guideline. Participants lived in 11 different neighborhoods with either high or low objectively determined walkability. The focus groups were transcribed verbatim, followed by a thematic analysis of the content with deductive and inductive code categories, utilizing the MAXQDA software. Results: Notable was the consensus of many perceived barriers and facilitators of active mobility and social participation along with their assignability to the same context (points-of-interest, infrastructure; safety, communication, community; topography, physical compositions, weather, aesthetics; personal / individual attitudes, influences, evaluations). Another main finding was that high and low walkability neighborhood-specific particularities were revealed that are in contrast to some objective characterizations of walkability: For example, too high density can inhibit active mobility, and too many options can inhibit social participation. Conclusions: The consensus of many barriers and facilitators of active mobility and social participation suggests that valuable synergies could be created by coordinating interventions aiming to promote both active mobility and social participation in urban neighborhoods. Also, considering subjective perceptions of residents helps to identify neighborhood-specific factors that determine (non) engagement in active mobility and social participation. The findings can help city planners and public health officials improve the promotion of active mobility and social participation in the creation of health-enhancing urban neighborhoods.

Background: Physical health (PH), including muscle strength, endurance, and the ability to perform daily physical tasks, gradually declines with increasing age, leading to disability and an increased disease burden. Both the urban community environment (UCE) and physical activity (PA) were linked to PH. Methods: A total of 625 participants aged 55 years and older from Haidian and Chaoyang Districts in Beijing, China, were included in the study from September to December 2023.PH was assessed by a combined score of four tests, including BMI, chronic disease, depression and self-rated health.The Neighborhood Environment Walkability Scale-Abbreviated (NEWS-A), Center for Epidemiological Survey-Depression Scale (CES-D), Physical Activity Scale for Elderly (PASE) and Social Support Rate Score (SSRS) were collected. The analysis was carried out with SPSS v.20 and Amos 24, and the results were validated via structural equation modeling (SEM). Results: The urban community environment was positively associated with the health level of older adults. Specifically, the standardized path coefficients indicate that the influence of the built environment (0.72–0.88) was greater than that of the social environment (0.43–0.55) and personal attributes (0.22–0.37) on older adults' health. Physical activity demonstrated both a mediating effect and an indirect effect, highlighting its significant value as a mediating variable. Conclusions: The urban community environment has a positive impact on promoting the physical health of older adults, with the influence of the built environment being greater than that of the social environment and personal attributes on their physical health. Physical activity acts as a mediator between the urban community environment and the physical health of older adults. [ABSTRACT FROM AUTHOR]

Walking, as a transportation mode, not only promotes individual well-being but also contributes to environmental sustainability. Though often neglected in the transport planning process that focuses primarily on motorized transport, the benefits of walking have recently renewed interests to enhance walkability. With the thematic focus on transport planning and network design, this paper first introduces a conceptual bi-level network design framework for enhancing walkability. Following the framework, we then conduct a thematic review focusing on modeling and enhancing walkability through transport planning and design elements. The identified studies are synthesized by answering the systematic classification scheme (SCS) questions. While recognizing the progress that has been achieved by previous studies, we conclude by exposing the challenges that remain and thereafter identifying potential directions for transportation research.

Problem, research strategy, and findings: As active transport planning gains momentum worldwide, our study underscores the importance of connecting people and places by focusing on the convenience dimension of walkability. Specifically, we used the pedestrian detour ratio (PDR) to measure the degree of circuity of a walking route. We considered residential buildings as origins and 10 different types of public facilities as destinations within the walkable range of 1 km. This led to a territory-wide analysis covering 3.85 million origin–destination pairs in Hong Kong. Overall, walking convenience was the best in the central business district (CBD), but variations existed by district and by facility. Through an assessment matrix, 35.8% of home–destination pairs required attention. When examined at the street block and village cluster levels, walking inconvenience was associated with vehicle-oriented street blocks (with higher vehicular traffic and more private parking spaces), high-income areas, and difficult terrain. Pedestrian crossings, major roads, and bus stops enhanced route directness. This research is a first step in helping quantify the PDR distribution across different cities and their various functional areas. Takeaway for practice: In areas where walking is inconvenient, treatments to calm vehicular traffic and facilitate pedestrian crossings should be stipulated. In the longer term, we recommend integrating the PDR in the design and planning of streets, especially around essential facilities. [ABSTRACT FROM AUTHOR]

Background Neighbourhood walkability can benefit cardiovascular health. Latino patients are more likely than non-Hispanic White patients to have diabetes, and evidence has shown better diabetes-related outcomes for patients living in neighbourhoods conducive to physical activity. Our objective was to determine whether neighbourhood walkability was associated with haemoglobin A1c (HbA1c) levels among English- and Spanish-preferring Latino patients compared to non-Hispanic White patients. Methods We used electronic health record data from patients in the OCHIN, Inc. network of community health centres (CHC) linked to public walkability data. Patients included those age ≥ 18 with ≥ 1 address recorded, with a study clinic visit from 2012 to 2020, and a type 2 diabetes diagnosis (N  = 159,289). Generalized estimating equations logistic regression, adjusted for relevant covariates, was used to model the primary binary outcome of always having HbA1c < 7 by language/ethnicity and walkability score. Results For all groups, the walkability score was not associated with higher odds and prevalence of always having HbA1c < 7. Non-Hispanic White patients were most likely to have HbA1c always < 7 (prevalence ranged from 32.8% [95%CI = 31.2–34.1] in the least walkable neighbourhoods to 33.4% [95% CI 34.4–34.7] in the most walkable), followed by English-preferring Latinos (28.6% [95%CI = 25.4–31.8]–30.7% [95% CI 29.0–32.3]) and Spanish-preferring Latinos (28.3% [95% CI 26.1–30.4]–29.3% [95% CI 28.2–30.3]). Conclusions While walkability score was not significantly associated with glycaemic control, control appeared to increase with walkability, suggesting other built environment factors, and their interaction with walkability and clinical care, may play key roles. Latino patients had a lower likelihood of HbA1c always < 7, demonstrating an opportunity for equity improvements in diabetes care. [ABSTRACT FROM AUTHOR]

Aging in place refers to staying in one's home well into older age. When gentrification occurs, older adults face financial challenges in sustaining affordable housing. Resident displacement results when moderate to high-income home buyers stream into neighborhoods and drive property values to prohibitive levels. Richardsville (pseudonym) is one of many communities in Atlanta's inner city that has transformed from a blighted, long-derelict area to a hotbed of high rent apartment units, mixed with quarter-million-dollar-plus homes. Richardsville Senior Residences, an affordable rental unit, was built to provide housing for a mix of incomes and ages and retain longtime residents in Atlanta's neighborhoods. In this community-based research project, we explore the lived experiences of eight older adults in a series of focus groups to discuss photographic images and give meaning to understand how they described aging in place. Common narratives among participants include access to outdoor spaces, smoke-free facilities, health and wellness, access to services, and social connections. [ABSTRACT FROM AUTHOR]

Aims: This study aimed to investigate the association between the time to achieve walkability after cardiac surgery and the risk of cardiovascular disease after hospital discharge. Methods: We conducted a prospective cohort study involving 553 ambulatory patients aged 71.5 (range, 64.0–77.0) years who underwent cardiac surgery. All patients were divided into five groups based on the time to achieve walkability ≥100 m within 1, 2, 3, 4 or 5 days after cardiac surgery. We examined the risk of post‐cardiovascular disease outcomes, including readmission due to heart failure, ischaemic heart disease and other cardiovascular disease, according to the time to achieve walkability with reference to 5 days using the Fine and Gray regression model, considering competing risks. Results: In the survival curve analysis, we examined the time to experience post‐cardiovascular disease incidence after hospital discharge. During a median of 3.3 years of follow‐up, 118 patients developed cardiovascular disease. We observed a positive association between the time to achieve walkability and cardiovascular disease risk, particularly heart failure. The multivariate hazard ratios (95% confidence intervals) for heart failure readmission were N/A (not assessed due to the sample size being too small) for 1 day, 0.31 (0.10–0.99) for 2 days, 0.60 (0.21–1.79) for 3 days and 0.76 (0.22–2.72) for 4 days (P for trend = 0.032). Conclusions: The shorter walkability achievement time was associated with a lower risk of cardiovascular diseases, more specifically heart failure readmission, among patients who underwent cardiac surgery. The time required to achieve walkability is a useful predictor for cardiovascular diseases after hospital discharge. [ABSTRACT FROM AUTHOR]

As urbanization rapidly progresses, streets have transitioned from mere transportation corridors to crucial spaces for daily life and social interaction. While past research has examined the impact of physical street characteristics on walkability, there is still a lack of large-scale quantitative assessments. This study systematically evaluates street walkability in Seongbuk District, Seoul, through the integration of streetscape images, machine learning, and space syntax. The physical characteristics of streets were extracted and analyzed in conjunction with space syntax to assess street accessibility, leading to a combined analysis of walkability and accessibility. The results reveal that the central and western regions of Seongbuk District outperform the eastern regions in overall street performance. Additionally, the study identifies four distinct street types based on their spatial distribution: high accessibility–high overall score, high accessibility–low overall score, low accessibility–high overall score, and low accessibility–low overall score. The findings not only provide a scientific basis for street development in Seongbuk District but also offer valuable insights for assessing and enhancing walkability in cities globally.

Urban high-density development has led to the emergence of complex three-dimensional pedestrian networks. As a crucial component of city centers, these networks significantly influence the spatial distribution of service industries. Understanding the correlation between pedestrian networks and service industry layouts is vital for effective planning and development. This study proposes a technical framework for analyzing the relationship between three-dimensional pedestrian networks and service industry layouts. Using the Xinjiekou central area in Nanjing as a case study, we constructed a three-dimensional pedestrian network model using the sDNA method. Focusing on catering formats, we introduced a method to study the spatial distribution characteristics of service industries in three-dimensional spaces and employed a graph convolutional network model to systematically analyze the correlation between pedestrian network closeness and betweenness with catering formats. The results indicate that pedestrian network closeness is significantly positively correlated with the number and average spending of catering formats, while betweenness shows almost no correlation. High-closeness areas, due to their traffic convenience and walkability, are more conducive to the concentration of catering formats and higher spending levels. Our findings provide valuable insights for catering format location decisions and the optimization of three-dimensional pedestrian networks, contributing to sustainable urban development.

Encouraging sustainable mobility through sidewalk condition improvement is a critical concern for urban transportation. Sidewalk condition affects pedestrian safety, satisfaction, and mobility inclusiveness. Early sidewalk defect detection and repair ensure transport justice by addressing pedestrian inequality caused by walkability issues. This study presents novel Sidewalk Defect Detection Models (SDDMs) using computer vision to identify and delineate sidewalk defect boundaries accurately. The SDDMs provide a cost‐effective and efficient sidewalk inspection method, achieving high accuracy in recognizing defects for concrete and brick materials (mIoU of 0.91 and mAP of 0.99 for concrete, mIoU of 0.90, and mAP of 0.97 for brick). Integrated with Google Street View for data acquisition, it offers a rapid solution for monitoring sidewalk conditions remotely, promoting sustainability through timely repairs. This research provides significant advancements in urban planning and transport research, ultimately improving pedestrian safety and satisfaction. Thus, it makes human settlements more inclusive, safe, and sustainable. [ABSTRACT FROM AUTHOR]

Good-quality urban street space is crucial for improving walkability. Frequency and amplitude are the main spatial characteristics of the street interface rhythm, known as a "virtual–real" relation. Exploring the mechanism influencing the urban street interface rhythm can help grasp the movement trend. In this study, the correlation between frequency and urban form is explored through a Pearson correlation analysis with multisource data, and the factors influencing the urban street interface rhythm are presented. The results indicate that frequency has a moderate negative correlation with the block scale and a moderate positive correlation with the number of pedestrian access entrances (PAE-n); the PAE-n also has a strong negative correlation with the block scale. Some spatial characteristics of outstanding streets from different countries are analyzed and discussed based on waveform classification. The regularities of interface rhythm that exist within multiple streets are found: multiple gaps on the street interface exist, acting as a "beat", which regularly integrates or separates the street interface rhythm. The frequency and amplitude of the "beat" significantly affect streets' walkability, and the amplitude is generally low and uniform, with good visual accessibility in all directions. A "Small Block and Dense Grid" becomes a key factor in improving walkability. Basic knowledge of the street interface rhythm in urban walking space research is supplemented by this study. Furthermore, theoretical guidance and parametric evidence are provided to improve walkability and promote the continuation of the traditional context. [ABSTRACT FROM AUTHOR]

The effects of the physical environment on people's active behaviour have been a central topic over the last decade, particularly in urban design, public health, and transportation. Research on the impact of the built environment attributes on walkability still needs to be completed in developing countries. Literature on walkability demonstrated the effectiveness of the studies, which consider micro-scale elements when evaluating pedestrian street environments. We are interested in assessing urban design qualities at the micro-scale level, which would give more evidence on the walking conditions of a developing country. This study explores whether the typo-morphological aspect of selected routes in a medium-sized African city is associated with urban design qualities related to walkability and compares the combined scores of urban design qualities with other cities. According to our findings, the typo-morphological aspect of urban routes correlates with the evaluated urban design qualities. The results revealed a significant difference in these qualities between the old colonial and the post-independence fabrics, with imageability and complexity appearing to be the most influential qualities. The results showed that urban design qualities related to walkability in a medium-sized African city scored lower than in other urban contexts. This study has several implications for city planners and decision-makers looking to improve the walking environment of the city.

The findings can help city planners and public health officials improve the promotion of active mobility and social participation in the creation of health-enhancing urban neighborhoods.

Pilgrimage represents a sacred journey to religiously significant places. Recent studies highlight a 35 times increase in travel to pilgrimage sites from 1991 to 2019 in India. This surge in pilgrim numbers underscores the growing need for improved mobility infrastructure to ensure a comfortable environment. The study investigates the relationship between street-level walkability indicators on mobility within a pilgrimage town, Nanjungud in India. Through field surveys, we documented four crucial environmental indicators tailored for Indian conditions: sidewalk availability, green view, aspect ratio, and connectivity. Both vehicle and pedestrian volumes are measured using gate count method at 22 different locations of the study area on weekdays and weekends. SPSS is utilized for analysing the correlation. The findings reveal a statistically significant, albeit moderate, correlation between sidewalk availability and pedestrian volume during day time (0.446). However, pedestrians were observed walking on the streets where the sidewalks are discontinuous. Additionally, there tends to be less of green view in the most populated streets, and a noticeable negative correlation of aspect ratio with sidewalk availability (−0.444). The study highlights the need to prioritize improvements in sidewalk infrastructure and urban shading enhancing the overall pilgrimage experience.

High-quality street spaces have a positive impact on residents’ lives. Revealing the differences in human perception and walkability across street spaces can highlight priority areas for street quality enhancement and provide valuable insights that help urban managers make informed decisions. This study first utilised machine learning models (SegNet) to extract visual elements from street view images and collected volunteers’ ratings of six perceptual dimensions of street scenes. Subsequently, it employed random forest algorithms and spatial autocorrelation models to predict and analyse overall street perception. Furthermore, principal component analysis was used to consolidate the six perceptual scores, coupled with an analysis of street walkability, to identify streets that most required quality enhancement. Finally, correlation and regression analyses were conducted between human perception ratings and street visual elements. The results indicated that buildings positively influence perceptions of wealth, safety, liveliness, and beauty and are the most significant positive perception elements. Conversely, walls were the most significant negative perception elements. Additionally, trees positively impacted perceptions of liveliness and beauty. Lastly, streets categorised as “high walkable-low perception” exhibited a radial dispersion from the city centre. In conclusion, the findings of this study provide valuable insights for enhancing street-space quality in Chengdu and other cities.

Abstract We examined the association between walkability and blood lipids in a nationally representative sample of 29,649 participants aged 3–79 years who participated in the Canadian Health Measures Survey (CHMS) cycles 1 to 6. We focused on seven lipid biomarkers: apolipoprotein A (Apo A), apolipoprotein B (Apo B), triglycerides (TG), high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), total cholesterol (TC), and TC/HDL. Cross-sectional associations were analyzed using generalized linear mixed models incorporating survey-specific sampling weights. An increase in the Canadian Active Living Environments Index, a measure of neighborhood walkability, equivalent to the magnitude of its interquartile range (IQR) was associated with the following percentage (95% confidence intervals (CI)) changes in lipids: decreased TG, -2.85 (-4.77, -0.93) and TC/HDL, -1.68 (-2.80, -0.56), and increased HDL, 1.68 (0.93, 2.42). Significant effects were largely restricted to adults (aged 17 to 79). In the younger age group there were no significant associations between walkability and lipids in the fully adjusted model. Significant associations were more frequently seen in females than males. For females, fully adjusted significant inverse associations were observed for TG, LDL, and TC/HDL, and there were positive associations with HDL and Apo A. Canadians living in more walkable neighborhoods have more favorable lipid profiles, suggesting that the built environment has the potential to influence the risk profile for cardiovascular health, especially among adults and females.

Abstract Streets and roads have been constantly identified as key spaces to improve walkability and—by extension—the entire urban environment. Such improvements lie on planning and design theories that are often supported by qualitative evidence and as such, tend to remain highly speculative on how street design influences walkability in more deterministic ways. Drawbacks in further exploring this street-walkability correlation are partly defined by an explicit rejection to ‘spatial determinism’ in urban morphology and social sciences, but also because combining differing epistemological approaches for understanding social processes linked to the physical aspects of the space is complex. In this paper, it is proposed that qualitative (social-based) theories of the space and quantitative (positivist) understandings of people’s behaviour can complement each other to elaborate upon ‘spatial determinism’ with focus on streetscapes and pedestrian behaviour. By using Agent-Based Modelling (ABMs), morphological components of streets linked to population characteristics are analysed to understand walkability from the perspective of spatial determinism. The findings suggest that the street settings directly affect pedestrian behaviour, and that changes in the built environment result in changes on walkability patterns. Ultimately, the modelling exercise shed light on street design and walkability, but also on wider debates on how urban design and social processes correlate in more deterministic and, therefore, predictable ways.

Abstract Background Increasingly, evidence has shown that different aspects of neighborhood context play a significant role in self-rated health, one of the key health indicators in advanced age. Nevertheless, very old adults are often under represented or excluded from such research. Therefore, the first aim of this study was to examine whether social, socioeconomic, and physical neighborhood context is associated with self-rated health in the very old population of Germany. The second objective was to explore whether the link of socioeconomic and physical neighborhood context with self-rated health is moderated by availability of social resources in neighborhoods. Methods Data from the representative survey, “Old Age in Germany” (D80+) were employed. In total, the study sample of D80+ included 10,578 individuals aged 80 years and over. Additionally, the D80+ data were matched with the freely accessible regional dataset of the Federal Institute for Research on Building, Urban Affairs, and Spatial Development. Two self-rated items (place attachment and social cohesion) were used to assess social neighborhood context. Socioeconomic context of neighborhoods was operationalized by German index of socioeconomic deprivation. To evaluate physical context, perceived measures of building conditions and walkability were included. Using the maximum likelihood estimator with robust standard errors, logistic regression models were estimated to analyze the relationship between neighborhood context (social, socioeconomic, and physical context, as well as their interactions) and self-rated health. Results Including 8,066 participants in the analysis, the findings showed that better condition of residential building, higher walkability, being closely attached to outdoor places, and higher social cohesion were associated with higher chance to report good self-rated health of very old adults. In the adjusted models, the German socioeconomic deprivation index was not related to self-rated health. The effect of socioeconomic and physical neighborhood context on self-rated health did not differ according available neighborhood social resources. Conclusions The results indicate that especially more favorable conditions in social and physical neighborhood context are associated with good self-rated health in the very old population of Germany. Further studies should consider multiple aspects of neighborhood context as well as their interplay when examining the neighborhood impact on self-rated health in older populations.

This paper focuses on studying the concept of walkability in Riyadh, Saudi Arabia, after the implementation of the Humanizing Neighborhoods Initiative. Al-Falah neighborhood was selected as a case study because it was one of the first neighborhoods to implement walkability strategies. By adopting a qualitative critical approach, this research collected data through a literature review and on-site observation to assess walkability in the neighborhood. Analysis of the observations highlighted the challenges and opportunities of walkability in Riyadh and the wider Gulf cities. Recommendations for promoting walkable communities in Riyadh include enhancing pedestrian infrastructure, incorporating mixed-use developments, integrating green infrastructure, implementing smart urban planning principles, and integrating public transportation systems. This paper emphasizes the importance of community engagement, preserving local identity, and involving various stakeholders to transform Riyadh into a pedestrian-friendly city that prioritizes public health and sustainability.

In this article, we examine two settlement types: a rural village and an urban neighborhood. Both settlements were built on state-owned lands, pre-planned, established over three generations ago, informed by the same planning theory, and inspired by the same national ideology. Given these similarities, we compare the values of their constructed environments. Through these values, we examine whether a village planned as a city retains its rural values, and whether an urban neighborhood can contain village construction values. The aim of this article is to examine whether the original planning has stood the test of time, in terms of rural and urban renewal. The research method involved the analysis of urban plans and observations of the built environment as a basis for evaluating the quality of the built environments. The findings and main contributions suggest that village and neighborhood planning based on optimal walking distances from the rural/urban centers and the high connectivity and visibility of both internal and external landscapes has provided both the village and neighborhood with a sound infrastructure for future changes, even decades later, and given a different set of needs. Nevertheless, whereas the village is based on a community, the neighborhood seeks to create one and, if it fails to do so, the open areas might become neglected, and the neighborhood might deteriorate. In such a case, only local activism or public intervention can improve the neighborhood's situation. This research constitutes an additional layer to studies examining the quality of the built environment, both in general and in Israel in particular, in cities and rural settlements. The case studies are Neighborhood D in Beersheba and the moshav Nahalal, Israel. [ABSTRACT FROM AUTHOR]

We examined the association between walkability and blood lipids in a nationally representative sample of 29,649 participants aged 3–79 years who participated in the Canadian Health Measures Survey (CHMS) cycles 1 to 6. We focused on seven lipid biomarkers: apolipoprotein A (Apo A), apolipoprotein B (Apo B), triglycerides (TG), high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), total cholesterol (TC), and TC/HDL. Cross-sectional associations were analyzed using generalized linear mixed models incorporating survey-specific sampling weights. An increase in the Canadian Active Living Environments Index, a measure of neighborhood walkability, equivalent to the magnitude of its interquartile range (IQR) was associated with the following percentage (95% confidence intervals (CI)) changes in lipids: decreased TG, -2.85 (-4.77, -0.93) and TC/HDL, -1.68 (-2.80, -0.56), and increased HDL, 1.68 (0.93, 2.42). Significant effects were largely restricted to adults (aged 17 to 79). In the younger age group there were no significant associations between walkability and lipids in the fully adjusted model. Significant associations were more frequently seen in females than males. For females, fully adjusted significant inverse associations were observed for TG, LDL, and TC/HDL, and there were positive associations with HDL and Apo A. Canadians living in more walkable neighborhoods have more favorable lipid profiles, suggesting that the built environment has the potential to influence the risk profile for cardiovascular health, especially among adults and females. Highlights: Blood lipids were measured in participants of the Canadian Health Measures Survey. Neighborhood walkability was measured by the Canadian Active Living Index. Increased walkability was associated with lower TG and TC/HDL and higher HDL. Favourable associations were more common in females. Increased walkability may improve cardiovascular risk profiles.

Doha, the capital city of Qatar, has experienced remarkable urban growth over the last two decades. This raises concerns regarding the city's fulfillment of compactness, complexity, and connectivity. This paper considers transit-oriented development (TOD) as a potential tool to attain a sustainable and diverse urban landscape in a situated context. Qualitative research methods, which include observations and mapping, are employed to gain a deeper understanding of the physical aspects of a situated context in the neighborhood of Al-Slata, Doha. Specifically, this paper aims to investigate the implementation of TOD in metro station precincts within Al-Slata based on five design aspects: (1) walkability; (2) balance of ground use; (3) mixed-use spaces; (4) intermodality and transportation hubs; and (5) a public transportation network. The findings include a lack of complexity and connectivity between urban activities and spaces adjacent to the metro station. In addition, these findings demonstrate the potential of metro stations to preserve the cultural heritage and social identity in a rapidly developing city like Doha. The recommendations include a layout design proposal to increase connectivity and complexity within the situated context and suggestions on how transit nodes and metro stations could become active hubs within the city.

This research explores the impact of urban design performance qualities on pedestrian behavior in a cultural heritage site designated by UNESCO. The study employs a multi-method approach, including a questionnaire survey, empirical observation of pedestrian activities, and empirical axial line and visibility graph analysis using the space syntax technique. The first part of the study involved a questionnaire formatted as a polling sheet to gather expert assessments of spatial performance measures. The second part used a pilot survey to capture the perspectives of end users regarding the study's objectives and their perceptions of the site. Pedestrian flow was observed using a technique called "gate counts", with observations recorded as video clips during specific morning and afternoon periods across three pedestrian zones. The study also examined the behavioral patterns of pedestrians, including their movement patterns. Finally, the ArcGIS 10.3.1 software was employed to evaluate the reliability of the results. The main finding of this research is that pedestrian behavior and walkability in the historical areas are significantly influenced by landmark integration, wayfinding behavior, and the socio-economic functions of heritage sites. This study highlights the importance of using cognitive and syntactic analysis, community engagement, and historical preservation to enhance walkability, accessibility, and social interaction in heritage contexts. In addition, it identifies the need for improvements in urban design to address inconsistencies between syntactic maps and actual pedestrian flow, emphasizing the role of imageability and the impact of environmental and aesthetic factors on pedestrian movement. This research provides valuable insights for urban designers and planners, environmental psychologists, architects, and policymakers by highlighting the key elements that make urban spaces walkable, aiming to enhance the quality of public spaces.

Environmental factors have been identified as having a direct relationship with physical activity (PA) and sedentary behavior. The main aim of this study was to investigate the relationship between microscale built-environment attributes and the levels of PA and sedentary behavior in young people. This study included 465 adolescents (55% girls) between 14 and 18 years from Valencia, Spain. Accelerometers and self-reported questionnaires were used to measure PA, including active commuting, and sedentary behavior, and the MAPS (Microscale Audit of Pedestrian Streetscapes)-Global tool was used for microscale variables. Mixed-effects regression models were used for data analysis. Higher levels of moderate-to-vigorous activity were identified when more positive elements were found in the street characteristics. Greater active commuting in the neighborhood had a positive relationship not only with more positive elements of land use and destinations but also with the overall score of the MAPS-Global tool. The sedentary levels were higher when higher levels of negative aesthetics and social characteristics were identified, and the participants were less sedentary when more bike facilities were observed. The main results of this study provide us with evidence of the relationship between the microscale variables of the built environment and both PA and sedentary behavior. [ABSTRACT FROM AUTHOR]

The walkability is closely related to the lifestyle and health of local residents. Unreasonable community design may result in spatially segregated spaces, creating walking barriers for residents and reducing walking accessibility. If a community's physical layout can be optimized through better walking-related planning at the community level, people would be more convenient to reach more facilities with a better walking accessibility. A microscale measurement method for walkability at the community level is necessary to assist in community planning. This study developed a new measurement of walkability using a hexagon-based adaptive crystal growth algorithm and verified its effectiveness by examining the impact of gated communities on walkability. Taking three communities in Beijing as cases, this study created two kinds of accessibility planes (with-wall and no-wall) to compare changes in walkability between gated and open communities. The findings show that gate and wall removal can partially improve community walkability and that the algorithm can accurately measure community walkability in different scenarios. The proposed algorithm provides a new perspective for walkability measurements and offers a scientific tool for people-oriented community planning. [ABSTRACT FROM AUTHOR]

Understanding the characteristics of urban street environment perception has important reference significance for both urban planning and renewal. Street view data has become an important data source for studying urban street environment features at present. Previous researches mainly evaluate street environment features (e. g., greening, walkability) in a certain dimension by semantic segmentation of street view images. However, it lacks the analysis of urban street classification based on multidimensional street perception characteristics. This study takes Xi'an as an example, based on the semantic segmentation results of Baidu Street View images, quantifies the perceptual characteristics of streets from five dimensions, namely greenness, openness, enclosure, walkability and imageability, and analyzes the spatial heterogeneity characteristics of the perceptual variables in each dimension. On this basis, the perceptual vectors describing the street environment are constructed with the perceptual variables of the five dimensions. X-Means clustering algorithm is used to cluster the street perceptual vectors and categorize the streets with similar perceptual characteristics. The results are shown as follows. (1) Street perception in Xi 'an presents spatial differentiation, in which the hot spots and cold spots of greenness perception are staggered, the spatial distribution of openness and imageability is gradual, and the enclosure and walkability are distributed in scattered clusters. (2) Streets can be divided into four categories based on perception characteristics, in which the difference between the categories of enclosure and walk-ability is small, while the difference between the other categories of perception variables is significant. The first category of streets (CD has the strongest greenness perception, the second category of streets (C2) has the strongest openness perception, the third category of streets (C3) has strong imaging perception, and the difference between the perception elements of the fourth category of streets (C4) is small. The results of this study are helpful to understand the spatial heterogeneity of urban street perception and provide reference for urban street renewal and planning. [ABSTRACT FROM AUTHOR]

Neighborhood planning models are crucial for ensuring a balanced distribution of urban services. Though the 15-min city model is the most updated neighborhood model, some gaps in the literature on schools and walkability exist. This paper addresses these gaps, especially in developing countries where servicing is challenging. This study focuses on evaluating school services through the lens of the 15-min city model to investigate the socio-spatial distribution of school locations. This research employs a multi-phase approach that integrates qualitative and quantitative methods to develop a methodological framework that was applied to the case study of Nablus. As a result, this study marks the gaps between implementing local schools and measures of the 15-min model in terms of physical, functional, and socioeconomic urban characteristics, including density, diversity, and proximity. It reveals the impact of local neighborhood planning on schools' efficiency in social sustainability, urban design quality, spatial coherence of schools, and coordination among schools and other services. Potential reforms in planning are provided. [ABSTRACT FROM AUTHOR]

This study reviewed previous studies on place attachment and related factors in the urban setting. Assessments were conducted on over one hundred peer-reviewed journal papers that met the selection criteria. The results were divided into six categories. Place attachment can improve each of the three dimensions of wellbeing. It can also mitigate the negative impacts of environmental stressors on wellbeing. Furthermore, traditional gardens and local landscape characteristics contribute to a stronger place attachment, depending on the degree to which they present local history and culture. Green landscapes can also help immigrants feel more connected to their community and place of origin. Social interaction has also been linked to the development of place attachment, which is stronger in low-income/deprived neighborhoods. Furthermore, higher place attachment promotes civic engagement and social trust. Place attachment also helps older people cope with aging difficulties in their living environments. Finally, there is a mutually beneficial association between place attachment and perceived neighborhood walkability, as well as a relationship between the scale of the place and the level of attachment. The various research gaps recognized by this study could be addressed in future studies to better understand the role of place attachment in creating sustainable urban environments.

Active transportation, with simple mobility modes such as walking and cycling, could be pivotal in addressing multiple sustainability challenges related to socio-economic, environmental, and public health issues. This paper investigates the facilitators for active transportation and assesses its impact on health, well-being, and urban sustainability. As a result, a multidimensional conceptual framework is developed to analyze the determinants influencing individuals' propensity to engage in active transportation and thereby lead to a sustainable, high-quality way of life. Through an extensive review of the relevant literature, key elements for active transportation, accessibility, and social inclusion are identified, and their potential impact on urban health and sustainability is investigated. Findings suggest that interrelationships between factors such as enhanced infrastructure, safety measures, and improved urban accessibility would significantly encourage active transportation usage. The proposed framework argues for a positive association between active transportation and improved health outcomes, contributing to sustainable urban environments. Furthermore, it is advocated that changing attitudes and mindsets could be achieved by urban planning and policy reforms supporting active transportation, as well as by effectively communicating the multiple benefits for individuals, the economy, and society at large. Comprehensive policy strategies, which include improvements in urban design and increased public awareness of the benefits of active transportation, could establish a paradigm shift for promoting a higher quality of life through a healthy, active, and sustainable urban lifestyle.

The walk score, which is widely used as an index of walkability, does not include pedestrian's perception, so there is a limit to explaining the level of perceived walkability in a neighborhood. The purpose of this study is to examine how an objectively measured walk score and subjectively measured environmental perceptions correlate with perceived neighborhood walkability. This study conducted a survey on 371 participants aged 18 or older living in Daegu, South Korea to examine perceived neighborhood walkability and perception of the built environment. We measured the walk score based on participants' location using a geographic information system. We used the quantile regression model, whereby we investigated the effects of explanatory variables (e.g., the walk score, perceptions of the built environment) by classifying perceived neighborhood walkability by quantile into Q10, Q25, Q50, Q75, and Q90. The walk score had a positive association with people with low perceived neighborhood walkability (Q10), but a negative association with people with high perceived neighborhood walkability (Q90). Regarding views of the built environment, in most quantiles, people perceived the environment as walkable if there were abundant green spaces and diverse alternative routes. Conversely, odors, smoke, hills, and stairs impeded walkability. This indicates that along with an objective walkability index, perceptions of the built environment play an important role in determining perceived neighborhood walkability. This implies that our results can help identify appropriate policies to promote walkability for citizens. [ABSTRACT FROM AUTHOR]

Background: Improving neighborhood walkability is critical for sustainable and livable urban development and is associated with increased physical activity. The Neighborhood Environment Walkability Scale-Abbreviated (NEWS-A) is a tool for assessing neighborhood walkability among adults. Currently, no Arabic version is available for this important walkability scale. Objective: To translate the NEWS-A to Arabic, culturally adapt, and pre-test it for adults. Methods: The NEWS-A was translated and culturally adapted using Crosscultural Survey Guidelines and then pre-tested using 65 households selected randomly from the neighborhoods of three districts in Riyadh. After answering the survey, 55 participants took part in a semi-structured cognitive interview, which sought their understanding of the words in the Arabic questionnaire, the clarity of each item, and their suggestions for improvement. Results: Translation and adaptation of NEWS-A to Arabic resulted in adding two items (mosque and healthcare center) to section B of the scale (stores, facilities, and other things in your neighborhood) and one related item to section C (access to services). The total individual items became 57 instead of the original 54 items in the English version. Also, we added "ATM machine" to item 14 (Bank/credit union) in section B. In addition, the overall results of the cognitive interview showed that most of the participants understood the intended meaning of the questionnaire (99.5%). Further, 99.8% of the respondents stated that the items were not difficult to comprehend, while 100% of the sample indicated that the sentences were comfortable and not sensitive to them. Conclusion: Translating, adapting, and pre-testing the NEWS-A resulted in retaining all the original items and adding three additional items. The Arabic NEWS-A provides an important tool for future research on neighborhood environment walkability among adults. [ABSTRACT FROM AUTHOR]

Numerous researchers have endeavored to amalgamate critical transit-oriented development (TOD) indicators, such as development density, walkability, and diversity, into a single TOD index to assess TOD performance. However, implementing TOD in megacities necessitates a more comprehensive selection of indicators, an objective calculation methodology, and accessible calculation data for the TOD index. This study introduces a method based on multi-indicator TOD performance assessment using multi-source urban big data; it uses Shanghai as a case study to evaluate and analyze the impact of site characteristics on performance. The method constructs the Comprehensive Socio-Economic Development Index (CSEDI) based on four indicators of TOD site operations. It establishes a multivariate regression model utilizing principal component analysis to extract 22 leading component indicators as independent variables from 71 indicators associated with TOD. Within the sample space of 77 rail transit TOD sites in Shanghai, the CSEDI exhibited a robust correlation with the independent variables. The evaluation results of the case study demonstrate consistency with the development characteristics of the city and the sites, indicating that the evaluation method can guide the renovation of existing sites and the development of new sites.
