Time Lapse Analysis of Users' Behaviors at Large-scale Intersections with Separated Traffic Signal Control

Abstract

 This study revealed the characteristics of users' behaviors at large-scale signalized intersections with separated traffic signal control through time lapse analysis. And we proposed a conflict risk estimate method between left-turn vehicles and pedestrians at signalized intersections and analyzed the performance of both types of traffic signal control at the surveyed intersection from the viewpoints of safety. After that, we confirmed the economic effects, which are based on the both aspects of safety and smoothness, by the introduction of separated traffic signal control for pedestrians.
