Quantitative analysis of lane-based pedestrian-vehicle conflict at a non-signalized marked crosswalk

Pedestrian-vehicle conflict is a common and dangerous event which occurs in both urban and rural areas in developing countries. Lane-based evaluation of pedestrian-vehicle conflict is still an open research topic in the traffic safety, urban planning, and city government communities. A lane-based approach for evaluating the post-encroachment time between pedestrians and vehicles was proposed. This study analyzed the lane-based distribution of pedestrian-vehicle conflict using collected video data which recorded the behaviors of vehicles and pedestrians in a non-signalized marked crosswalk in Wuhan, China, and discussed the effect of waiting time on lane-based pedestrian-vehicle conflict as well as the distribution of pedestrian walking speed under different levels of severity of lane-based pedestrian-vehicle conflict. Experimental results showed that shorter waiting times and smaller waiting areas are very strongly related to lane-based conflict, but that walking speed is not a significant factor in lane-based pedestrian-vehicle conflict.
