Aside from accidents caused by pedestrian signal violation, crashes between pedestrians and turning vehicles also happen frequently. At most signalized intersections in China, pedestrians are released together with the parallel right-turn vehicles, which results in frequent conflicts between the pedestrians and the turning vehicles. An empirical study has been carried out at three typical crosswalks at signalized intersections in Shanghai. It has been found pedestrians yield twice as often as right-turning vehicles. Based on a Pearson correlation analysis, the key factors of pedestrian yielding behavior are identified, which includes the existence of a pedestrian group, group population, crossing direction, disturbance of non-motorized vehicles, the volume of right-turn vehicles, the distance to the conflict point of pedestrians, and the time difference between pedestrians and right-turn vehicles arriving at the conflict point. A binary logistic regression model has been developed for the pedestrian's yielding decision, followed by an elasticity analysis of influencing factors.
