Analysis of Elementary School Children’s Street Crossing Safety Behavior Based on Random Parameters Ordered Logit Model

Abstract

In the context of rapid urbanization and increasingly diverse modes of transportation, urban traffic safety issues are becoming more pronounced. Elementary school children, as a vulnerable group in traffic environments, face significant challenges in ensuring safe street crossings. Therefore, it is crucial to conduct an in-depth exploration of the potential threats and hazards associated with their daily street crossing behaviors to mitigate road safety risks. This study carried out a field investigation at signalized intersections, aiming to thoroughly analyze the intrinsic connection between elementary school children’s street crossing behaviors and the severity of traffic conflicts. The random-parameter ordered logit model is used to analyze the data. The results show that intersection characteristics, unsafe behaviors, and the attributes of the road crossers significantly influence the severity of traffic conflicts. Specifically, shorter green light durations, shorter signal cycle lengths, and smaller crosswalk dimensions exacerbate conflict severity. While restricting right-turn signals can reduce moderate and minor conflicts to some extent, it may lead to more severe conflicts. Furthermore, unsafe behaviors such as running red lights and rushing across streets significantly increase the risk of severe conflicts, especially when children cross alone. Notably, the law-abiding behaviors of adults also affect the severity of conflicts. To enhance street crossing safety for elementary school children, it is recommended to extend green light durations, appropriately adjust crosswalk dimensions, and strengthen traffic safety education. Collaboration between parents and schools is essential to promote traffic safety education for children through example and supervision.
