Study on Pedestrian Crossing Behavior at Signalized Intersections

Perumal, Vedagiri

A clear understanding of the pedestrian crossing behavior under mixed traffic conditions is needed to provide the necessary infrastructure and also for enhancing pedestrian safety at signalized intersections. This paper attempts to analyze the crossing behavior of pedestrians (including crossing speed, compliance with signal, and pedestrian-vehicular interaction under mixed traffic conditions) and to identify the influencing factors based on statistical tests. A total of 775 pedestrian samples were observed from three signalized intersections in Mumbai, India for analyzing crossing behaviors. The significant factors affecting traffic signal compliance by pedestrians were identified by conducting Pearson's correlation coefficient test, the ANOVA test, and the Student t test. Factors influencing pedestrian crossing speed have been studied and design crossing speeds have been determined for old and adult pedestrians as 0.95 m/s and 1.12 m/s, respectively. Logistic regression models have been developed in which the odds of pedestrian violation and interactions are modeled and verified. This study can help researchers and practitioners to understand pedestrian crossing behavior at signalized intersections and to develop pedestrian delay models under mixed traffic conditions.
