Analysis of factors affecting pedestrian-vehicle conflicts on traffic circle exit roads
To effectively reduce the conflict between pedestrians and vehicles and avoid traffic accidents as much as possible,the link between pedestrian behavior and traffic conflicts is studied.The data of pedestrian-vehicle conflicts during the peak hours were collected,suitable traffic conflict indicators were selected,cluster analysis was conducted to derive the thresholds of different types of traffic conflicts and the severity of different types of pedestrian-vehicle conflicts,and the concept of hazard was introduced to conclude that small exit lanes are more dangerous than large exit lanes.The correlation between pedestrian characteristics and pedestrian-vehicle conflicts was further explored,and it was found that there was a positive linear relationship between pedestrian violation rate and conflicts,and a negative correlation between crossing queue size and conflicts.Pedestrian gaze direction from vehicle direction to crossing direction when conflict is about to occur will greatly reduce the occurrence of conflict.
