Red-light violations of pedestrians crossing at signal intersections is one of the key factors in pedestrian traffic accidents. Even though there are various studies on pedestrian behavior and pedestrian traffic conflicts, few focus on the risk of different crosswalks for the violating pedestrian group. Due to the spatio-temporal nature of violation risk, this study proposes a geographical and temporal risk evaluation method for pedestrian red-light violations, which combines actual survey and video acquisition. First, in the geographical-based risk evaluation, the pedestrian violation rate at signal intersections is investigated by Pearson correlation analysis to extract the significant influencing factors from traffic conditions, built environment, and crosswalk facilities. Second, in the temporal-based risk evaluation, the survival analysis method is developed to quantify the risk of pedestrian violation in different scenarios as time passes by. Finally, this study selects 16 typical signalized intersections in Suzhou, China, with 881 pedestrian crosswalk violations from a total size of 4586 pedestrians as survey cases. Results indicate that crossing distance, traffic volume on the crosswalk, red-light time, and crosswalk-type variables all contribute to the effect of pedestrian violation from a geographical perspective, and the installation of waiting refuge islands has the most significant impact. From the temporal perspective, the increases in red-light time, number of lanes, and traffic volume have a mitigating effect on the violations with pedestrian waiting time increases. This study aims to provide a development-oriented path by proposing an analytical framework that reconsiders geographical and temporal risk factors of violation. The findings could help transport planners understand the effect of pedestrian violation-related traffic risk and develop operational measures and crosswalk design schemes for controlling pedestrian violations occurring in local communities.

The main purpose of the article is to study the infrastructure of multimodal transportation in the context of changes in transport and logistics routes. The object of research is the infrastructure of multimodal transportation. The main issue of the study is to determine ways to develop the infrastructure of multimodal transportation in the context of changing transport and logistics routes. For this, a modern methodology of functional modeling was used. As a result, a model was obtained that, in a graphical language, represents the main aspects of the development of the multimodal transportation infrastructure in the context of changes in transport and logistics routes. The focus of the study falls on Ukraine and its transport infrastructure. The article explores the development of multimodal transportation infrastructure in the context of changing transport and logistics routes. Showing the loss of the size of cargo transshipment by the seaports of the annexation of the area. The features of the functioning of seaports in an aggressive environment are described. Empirically, the potential volume of cargo transshipment and the volume of exports by seaports for a single country under different conditions have been established. Empirically established the volume of losses of container handling of goods. The study is limited by taking into account the multimodal transportation infrastructure of only one country taken.

With the rapid development of complex networks, the research on robustness has gradually attracted the attention of scholars. In this paper, the research mainly focuses on the analysis of the stability and vulnerability of probability routing strategy on interconnection networks. Firstly, random attacks or target attacks are carried out on the network, and then its maximum connected subgraph is calculated, and the routing strategy is applied to the maximum connected subgraph. This paper evaluates the strategy’s robustness by examining some network parameters. Simulation outcomes reveal that in comparison to effective routing and the shortest path routing strategies, the probability routing strategy demonstrates superior robustness, evidenced by its performance in terms of network traffic capacity and average path length.
