Abstract:

Pedestrianvehicle conflict is an important factor affecting the traffic capacity of signalized intersections in urban roads. By selecting typical signalized intersections, the conflict behavior between pedestrian stacking and rightturning vehicles was analyzed in this paper. Traffic states of the intersection at Beijing Naoshikou street and Xuanwu gate west street were videotaped during peak hours. Based on the captured video recording, the spatial distribution characteristic data of the waiting pedestrians and rightturning vehicle were extracted. According to the data, the related factors that influence the right turn of motor vehicle were analyzed. And the relationship between the various factors and vehicle delay was explained by linear regression analysis. Studies found that the number of pedestrians piled up has the greatest impact on the delay of rightturning vehicle and there is a strong linear relationship between them. It is of practical significance to reduce or avoid the conflict between pedestrian and vehicle in the future traffic management control.
