Abstract

Pedestrian red-light violation is one of the crucial causes of pedestrian crashes at urban intersections, which cause considerable injuries and casualties to this vulnerable road group of road users. The objective of this study is to evaluate the risk of pedestrian-vehicle collisions by clustering the pedestrians' red-light violations using surrogate safety measures. The present study utilized surveillance camera footage to collect data on pedestrians' red-light violations at two urban intersections in Babol City. Based on critical thresholds of post-encroachment time (PET), Time to Collision (TTC), and Gap Time (GT), three different risk levels of red-light violations were identified through the use of a K-means algorithm. Moreover, structural equation models were developed for each of the risk levels considering variables that are associated with four major components: human, environment, road, and vehicle. Lastly, policy insights into amending pedestrian behavior and promoting traffic safety culture were proposed, with an overarching emphasis on the human factor, due to its identified greater influence on the propensity for red-light violations.

基于替代安全措施的行人红灯违规行为风险评估:人、路、车、环境因素的影响

行人闯红灯是造成城市十字路口行人交通事故的重要原因之一，对道路使用者这一弱势道路群体造成了相当大的伤害和伤亡。本研究的目的是利用替代安全措施对行人的红灯违规行为进行聚类，以评估行人与车辆碰撞的风险。本研究利用监控录像来收集巴博勒市两个城市十字路口行人违反红灯的数据。基于入侵后时间(PET)、碰撞时间(TTC)和间隙时间(GT)的临界阈值，利用K-means算法识别出三种不同的红灯违规风险等级。此外，考虑到与四个主要组成部分相关的变量:人、环境、道路和车辆，为每个风险级别开发了结构方程模型。最后，提出了改变行人行为和促进交通安全文化的政策见解，并强调了人为因素，因为人为因素对红灯违规倾向的影响更大。

期刊介绍： First published in 1977 as an international journal sponsored by the International Association of Traffic and Safety Sciences, IATSS Research has contributed to the dissemination of interdisciplinary wisdom on ideal mobility, particularly in Asia. IATSS Research is an international refereed journal providing a platform for the exchange of scientific findings on transportation and safety across a wide range of academic fields, with particular emphasis on the links between scientific findings and practice in society and cultural contexts. IATSS Research welcomes submission of original research articles and reviews that satisfy the following conditions: 1.Relevant to transportation and safety, and the multiple impacts of transportation systems on security, human health, and the environment. 2.Contains important policy and practical implications based on scientific evidence in the applicable academic field. In addition to welcoming general submissions, IATSS Research occasionally plans and publishes special feature sections and special issues composed of invited articles addressing specific topics.
