In the paper the idea of multi-storey overground garage with capacity of 400 cars in both directions is presented. The garage would be a good solution to the parking problems in the city centers nearby factories, offices and other public buildings. [ABSTRACT FROM AUTHOR]

Cyclists as unprotected road users are one of the most vulnerable groups of travelers. In order to improve their safety, various activities are carried out. Interested results are presented in Mineta Transportation Institute (MTI) report - Report 12-54: Bike-sharing and Bicycle Safety from 2016. It points out that there are no fatalities among users of city bike sharing systems in the United States. Due to the growing interest in systems in Poland, authors focused on the analysis of aspects related to the safety of their use. The paper presents factors that affect the road traffic safety of bike-sharing users. Authors referred to international practices used in cities bike-sharing systems and presented bike-sharing systems as an opportunity to support the implementation of Vision Zero.

The integration of shared and autonomous mobility has led to the emergence of shared autonomous vehicles with ride-sharing services (SAVWRS), which have the potential to significantly reduce private car usage and promote sustainable transportation. Despite numerous studies on this topic, there is still no research examining the impact of all dimensions of perceived risk theory on usage intention. Therefore, we aim to investigate these relationships and gain deeper insights by examining the mediating effect of trust and the moderating effect of generation (Millennials vs. Baby Boomers) to address potential disparities across generations. To gather insights, we design an online survey that was completed by a random sample of 723 individuals in 2021. The estimation results of the structural equation model reveal that all perceived risk dimensions (social, performance, time, physical, security, and financial risks, in descending order) are negatively related to consumers' intention. Additionally, trust fully mediates the relationships between performance, physical, financial, and security risks and usage intention, whereas it partially mediates the relationships between social and time risks and the intention to use. Furthermore, moderation analysis revealed that Millennials are less concerned about most dimensions of perceived risk theory, except for social and time risks. In conclusion, our study contributes to a deeper understanding of the complex relationships between perceived risk dimensions, trust, and usage intention in SAVWRS. Our findings suggest that policymakers and industry stakeholders should consider strategies to address these concerns to promote widespread acceptance of SAVWRS., (© 2024. The Author(s).)

The determinants of children's independent school mobility and the contextual discrepancies between these determinants have not been comprehensively investigated in previous studies. It is important to examine these determinants because independent school mobility is associated with children's physical activity, according to the literature. This paper examined the associations of different groups of variables such as household, mobility, perceptions, and the built environment with independent school mobility of children between 9 and 12 years using a sample of 1304 girls (50.9%) and boys (49.1%) in seven European countries. The sample was analyzed by Multinomial Logistic Regression, Chi-square test of independence, and Proportional Reduction in Error methods. According to the findings, father's and mother's commute mode choice, child's mode choice of commute to school, child's bike ownership, parent's perception of safety, parent's evaluation of bike lane and sidewalk quality, child's commute distance, number of driving licenses in the household, accessibility of public transport, and population density in the neighborhood and around the school proved to be very strong and significant determinants of children's independent school mobility in the Europe-wide sample. The comparison of the levels of independent school mobility did not show any significant differences between high-income countries such as Germany, Italy, and the Netherlands, and emerging economies and developing countries like Poland, Greece, Turkey, and Croatia. However, a direct comparison between Poland (emerging economy) (33.6%) and the Netherlands (high-income) (31.7%) revealed significant differences in the level of independent school mobility. This study found the motives for this discrepancy due to the significant difference in bike ownership, the number of household members working outside of the house, household size, commute distances of parents, and driving license possession.
