The area where vehicles conduct interchanges is designated as the on-ramp merging area. The traffic efficiency in the ramp merging area drastically decreases if the mainline and ramp traffic flow density reaches saturation. As a current research hotspot in transportation, intelligent network technology, relying on the high- precision motion control and high-efficiency communication of connected-automated vehicle (CAV), can significantly improve the traffic efficiency in the merging area. The fusion strategies used by CAV are assessed in this research utilizing three different control paradigms: feedback control, optimal control, and reinforcement learning. The shortcomings of the three methods in this scenario are summarized, and specific improvement measures are given by reviewing existing research. Also, it offers a thorough summary of the most recent developments and trends in this particular scientific field. [ABSTRACT FROM AUTHOR]

The green construction evaluation system of the Xinyi expressway electromechanical installation, comprising 19 indicators, has been constructed using the IAHP, CRITIC, and grey clustering method. This system was developed based on the Xinyi expressway electromechanical installation project, which involved the use of the IAHP, CRITIC, and grey clustering method. The system was constructed from four aspects: comprehensive management level, resource saving and utilization, construction quality impact, and ecological environment impact. The green construction grade of the electromechanical installation of the selected five bidding sections is evaluated in a comprehensive manner, and the advantages and disadvantages of the selected bidding sections are analyzed using a radar chart method. The research findings indicate that the primary determinants of the green construction evaluation level of the project are the prefabrication rate of component parts, the vegetation restoration rate, and the utilization rate of environmental protection technology. Once the selected bidding section has achieved a higher grade in the green construction evaluation, the monitoring data of the electromechanical installation's green construction meets the requirements of the specification, and the level of green construction is close to the actual production of the project. This proves that the method is scientific and rational and provides a reference for the green construction evaluation of similar electromechanical installation projects in the future.

In order to reduce traffic accidents caused by light intensity differences, based on the Xinyi expressway project, a combined structure of reinforced concrete and steel structure was installed in the Songjiawa-Shuigouhe adjacent tunnel connection section. The length of the sunshade was calculated based on the speed limit, DIALux simulation software was utilized to investigate two working conditions at different time, and the carbon emission factor method was used to analyze the carbon emissions under different working conditions. The results show that the length of the sunshade in the adjacent tunnel connection section is 100 m. After the installation of the sunshade, the reduction rate of road illuminance reaches 57.97%, the overall illuminance uniformity is greater than 0.4, and the error between the on-site measured value and the simulated value is within 10%, both of them meet the requirements of the relevant standard. In addition, after the installation of the sunshade, the annual carbon emissions can be reduced by 82.56 t CO2e, the carbon emissions generated during construction can be offset after 2.8 a of operation, and the construction costs will be recouped after 3.7 a. During the service life, the carbon emissions are reduced by 3 795.74 t CO2e and the costs are saved by 5.773 1 million yuan, the dual effects of emission reduction and cost savings can be achieved.

The highway project from Weifang to Qingdao and its connection line, pass through the active Anqiu-Juxian fault zone. To ascertain the precise distribution, tectonic characteristics, and activity of the Anqiu-Juxian fault within the area of the project, the regional geological structures was firstly studied. It was initially deduced that the Anqiu-Juxian Fault passes through the project in the vicinity of Caocun, which served as the foundation for accurate fault positioning and activity identification. Secondly, through remote sensing, field geological investigation and mapping, the micro-geomorphology and outcrop features of distribution of the fault were discussed. Through seismic geophysical survey on the shallow strata, the distribution pattern of the fault inside the strata were conducted. Through drilling exploration, specific distribution features and activity of the fault were revealed and confirmed. Finally, further analysis of the fault's activity period was conducted by referencing to C14 dating and optically stimulated luminescence dating results from projects nearby. The research results show that, the eastern and western branches of the Anqiu-Juxian fault intersect with the highway project in the vicinity of K24 + 900 and K23 + 550 respectively. The fault's activity period dates back to the Late Pleistocene and Holocene epochs of the Quaternary period, and the F1 and F2 faults on either side are pre-Quaternary faults. After comprehensive analysis and deliberation, it has been established that the eastern and western branches of the Anqiu-Juxian fault show relatively stronger activity within the project area, posing significant influence on the proposed highway. While the activity of the F1 and F2 faults is relatively weaker, exerting less impact on the proposed highway. In accordance with the research results, the new highway adopts general subgrade to traverse distribution zone of the fault. [ABSTRACT FROM AUTHOR]

Aiming at the problem of traffic congestion in freeway on-ramp entrance under the condition of high traffic flow, this paper proposed a cooperative merging control solution of connected and automated vehicles（CAVs） at freeway on-ramp entrance, which divided the problem into two parts: multi-vehicle sequential decision making and vehicle motion planning. Multi-vehicle sequential decision making played an important role in traffic efficiency, so this paper proposed a multi-vehicle sequential decision algorithm based on the state evaluation model（SEM）, the algorithm first established the state space and initialization, considered the traffic efficiency and the vehicle delay design state evaluation function, select the optimal state through the state transition relationship, and finally got the optimal passing order by backtracking. According to the state of the vehicles and the time to reach the conflict point, the controller deduced the analytic solution of the longitudinal velocity of each vehicle in real time to realize the vehicle motion planning. Simulation and experiment results show that the solution can not only meet the real-time requirements of the traffic system, but also effectively improve the efficiency of freeway on-ramp entrance, shorten vehicle delay and reduce fuel consumption.

Objectives: In July 2021, Henan Province of China suffered continuous extreme rainfalls, causing widespread flood and serious paralysis of the highway network. The flood caused by the heavy rainfalls brought enormous loss to people􀆳s lives and properties in Henan Province. Methods: We collectively used a range of earth observations, namely remote sensing images from Sentinel-1 and Gaofen-3 satellites, rainfall and water vapor data from the European Centre for Medium-Range Weather Forecasts, and geohazard survey data to investigate and analyze the evolving process of the flood caused by the heavy rainfalls in Henan Province, and proposed a new technical framework for rapid assessment of traffic inefficiency under flood scenarios over wide regions. Results: The application of the new framework to the case in Henan Province suggests that: (1) The cumulative rainfall was highly concentrated, reaching a historic high level and affecting a wide region. (2) The total affected area in Zhengzhou City, Henan Province and its surrounding areas reached 3 800 km². (3) The potential of secondary landslides in mountainous areas such as Sanmenxia City and Dengfeng City was highly increased.(4) About 1 300.46 km of major roads were affected by this flood, and the overall connectivity of major highway networks in Zhengzhou and its surrounding five cities decreased about 21.27%, with 34.22% for expressways, 13.78% for national highways, and 14.86% for provincial highways. Conclusions: This study shows how to integrate remote sensing, secondary landslide analysis, road network analysis, and other multi‐field technologies to construct a framework for traffic inefficiency assessment under natural hazards. It is believed that this framework could be applied to other hazardous events and provide valuable information for emergency rescue. [ABSTRACT FROM AUTHOR]

The second-by-second vehicle license plate record data in 2017 was obtained through the Foshan video bayonet. Taking " Foshan First Ring Road" as the boundary, the hourly-scale different vehicle types of non-local vehicles inside and outside the region, the travel and technology parameters time-varying characteristics of road types are studied. The results show that: (1) The average daily travel volume of non-local vehicles in Foshan accounts for 24.11% of the total vehicles in the city, which is similar to the proportion of non-local vehicles (23%) in large provincial capital cities. Among them, the traffic volume of heavy and light vehicles is significantly different inside and outside the "Foshan First Ring Road" (over 50%). (2) Vehicles from other places inside and outside the province are mainly from Guangzhou, Zhaoqing, Guangxi and Zhejiang, and are mainly distributed on the Guangfo connecting channel. The emission standards of non-local trucks and trucks in the province are mainly China IV (38.9%-44.6%), and the fuel type is mainly diesel (78.0%-78.4%). (3) From the point of view of hourly traffic flow, the hourly traffic volume of non-local vehicles inside the "Foshan First Ring Road" is higher than that outside the "Foshan First Ring Road". In the daytime, the total traffic volume of non-local vehicles, and the traffic volume of non-local vehicles distributed according to different vehice types are both about 3 times that of the night-time. From the perspective of the emission standards of non-local vehicles in the province, the hourly traffic volume of China IV vehicle is the highest; at the same time, non-local vehicles mainly appear on expressways and national and provincial roads.

Compared with the traditional mode, expressway BOT+EPC mode has incomparable advantages in financing, construction, and other aspects, but it is prone to inconsistent phenomena before and after construction from project investment to operation stage. This paper constructs the success evaluation system of expressway BOT + EPC project by integrating the characteristics of the success evaluation method, which is comprehensive, efficient, and clear in its conclusions . Then, the whitening weight function is constructed based on grey theory to quantify the indexes. After that, the index weight are determined through the analytic hierarchy process and grey correlation degree. The project success value is calculated based on a comprehensive fuzzy method. Finally, the comprehensive and multi-level project post-evaluation is realized. KK expressway example results show that the project's overall success is 4.029, belonging to the basic success. However, the success degree of the project operation effect and benefit is only 3.799, which belongs to partial success. The main reason is that the actual traffic volume is lower than expected. In the later stage, it is necessary to improve the anti-risk ability of the financial part and pay attention to the research depth of similar BOT+EPC projects in the decision-making stage.

To solve the problem of congestion in the interweaving area of Nanjing inner ring expressway during rush hour, an non-interrupt weaving area control strategy was proposed based on five-lane weaving area with 2 ramps for vehicles driving in 4.5 lanes on average. For the priority to improve the main road capacity and increase the speed of weaving vehicles, the traffic diversion of weaving and non-weaving traffic flow in advance made the vehicles run orderly, and the number of available lanes for weaving traffic flow was increased by one-way lane changing on the ramp. The capacity and the influence factors of service level in weaving area were analyzed, and three methods of speeding up, access control and sign-and-marks control were introduced for alleviating traffic congestion. The non-interrupt weaving area control strategy of vehicles driving in 4.5 lanes on average was proposed, and the simulation models were built to compare the average speeds of main road and side road in different schemes by VISSIM. The results show that under the conditions of heavy traffic and small interweave ratio in the weaving area, compared with no control measures, scheme B 4.5 lane weaving with one-way lane changing on the auxiliary line has significant effect in optimizing the main line driving speed with average increasing of more than 8%, and scheme D of one-way lane changing on the auxiliary line with separation of flow lines has significant effect in increasing the auxiliary line driving speed with average increasing of 6%-24%.

In order to carry out the correction work of traffic simulation model more efficiently, this paper proposed a model correction framework based on parameter sensitivity analysis . The method simplified the model by exploring the key parameters that affected the model accuracy through sensitivity analysis, and corrected the model with the usage of the calibrated key parameters. To justify this, the paper analyzed the car following model and lane changing model under the simulation condition of urban expressway weaving area. Firstly, it obtained the value of model parameters under different traffic flow levels through a large number of simulation experiments. Secondly, this paper formulated the interval division rules and cross combination rules of model parameters to improve LH-OAT algorithm and genetic algorithm (GA) . Then, it used the improved LH-OAT algorithm (ILH-OAT ) and GA algorithm to analyze the sensitivity of the model parameters and used GA to calibrate the key parameters. Finally, this paper checked the error of the simulation results according to the verification index. The results show that the combination of ILH-OAT and GA simplifies the simulation model and reduces the simulation operation cost. Besides, it also adds verisimilitude to the simulation on reflecting real traffic operation. [ABSTRACT FROM AUTHOR]

Objectives: With the acceleration of urbanization, problems caused by extreme weather such as heavy rain have become increasingly obvious. As one of the most common meteorological disasters, urban floods have become one of the urban diseases in today's big cities. Therefore, it is necessary to explore the methods and technologies of multisource spatiotemporal data integration to achieve dynamic road waterlogging visualization. Methods: Firstly, we designed a spatiotemporal data model of road waterlogging and stored the data in the form of database tables to describe the evolution process of road waterlogging in both time and space. Secondly, a matching method for waterlogging data and road data was put forward to obtain road waterlogging depth. Thirdly, we designed a prototype system for dynamic road waterlogging warnings and achieved the extraction and release of road waterlogging depth. Finally, an experiment was carried out in downtown Nanjing City to verify the availability of the proposed method. Results: The results show that the proposed data integration method can meet the multi-scale needs of dynamic road waterlogging visualization. We integrate multisource spatiotemporal data from the perspective of dynamic road waterlogging visualization to solve the problem of transferring multi-source data into road waterlogging depth. Conclusions: In further studies, real-time traffic will be considered to comprehensively express the road condition and waterlogging condition. [ABSTRACT FROM AUTHOR]

The Chinese-American geographer Yi-Fu Tuan in 1977 provided an insightful way to imagine the difference between "space" and "place." His brief summary reveals the paradoxical tension between them: "Place is security, space is freedom: we are attached to the one and long for the other." The history of urban and regional development in the post-World War II United States can be understood as an effort to recover the value of place in the wake of the rapid expansion of interstate highway systems that expanded the freedom of space at the expense of treasured places. Especially since the turn of the millennium, public artists have played a key role in helping to restore a balance between space and place, often as part of "creative placemaking" in the rail transit corridors that have become increasingly prevalent. In 2021, the American Planning Association released a study that identified seven prototypes describing ways in which the arts and culture have contributed to harmonizing space (in the of form high quality transit providing freedom of movement) and place (in the form of preserving and revitalizing neighborhoods near transit stations). These prototypes can provide useful guidance to place remaking efforts in many contexts, not just transit. [ABSTRACT FROM AUTHOR]

Taking the Muzhailing Highway Tunnel of Weiwu Expressway as the engineering background, the characteristics and mechanism of the large deformation of the high-stress carbonaceous slate tunnel were analyzed through the records of typical large-deformation disasters and rock mass characteristics. The results of the study showed that the carbonaceous slate tunnel mainly had two large deformation modes, namely conventional type and sudden type; for different lithological sections, the deformation of the surrounding rock was generally expressed as "corrugated developed carbonaceous slate section> thin monoclinic structural carbonaceous slate section> layered carbonaceous slate interbedded with sandy slate section (interbedded section)"; the deformation mechanism of carbonaceous slate mainly included "slab beam" bending deformation, interlayered structure bedding-slip and plastic flow. The corrugated development section was dominated by plastic flow, the thin monoclinic structure section was dominated by "slab beam" bending deformation, and the interbedded section was dominated by bedding-slip.

In view of the difficult to recover vehicle trajectory in the expressway, this paper proposed an improved object ReID algorithm based on ETC gantry frame system to enhance vehicle trajectory recovery results. The key innovation of the proposed algorithm was combining license plate recognition and ReID in modified FairMOT network. In particular, it took the license plate, vehicle color, vehicle type, vehicle brand and ReID as the multi-output branch of the training network.The proposed network could quickly extract property and ReID information of numerous rapid objects in expressway compared to previous network. It also developed a labeling software and dataset to deal with multi-object labeling, multi-tab labeling and ReID labeling. Experimental result shows that the proposed algorithm obtains 97.32% accuracy of vehicle license plate recognition,86.94%rank-1 of vehicle re-identification, and 85% accuracy of vehicle trajectory recovery which is 14.8% and 9.89% higher respectively than the previous methods which only use ReID or vehicle license plate recognition .In the actual expressway scene, this method can run at 27.5 fps with good vehicle trajectory recovery results. In addition, this work shows that intelligent algorithm has good application prospect in the field of expressway. [ABSTRACT FROM AUTHOR]
