Abstract
To alleviate the conflict problem between right-turning vehicles and crossing pedestrians at signal intersections, this paper uses the right-turn delayed release behavior control strategy to analyze the intersection's pedestrian-vehicle conflict characteristics, selects the delay and the number of conflicts as evaluation indexes for efficiency and safety, and uses the entropy weighting method for weighting to establish comprehensive indexes, so as to explore the changes of comprehensive index scores under different pedestrian and right-turning traffic, and finally in VISSIM simulation software, through the COM interface using python programming language for its secondary development, build the intersection conflict environment for simulation experiments, and analyze the simulation results. The results show that when the rightturn flow is between 200 pcu/h and 500 pcu/h and the two-way pedestrian crosswalk flow is not less than 400 ped/h, the composite index scores are improved after setting the right-turn delayed release phase.
