Key design points and simulation analysis of pedestrian twice crossing based on detailed design concept

In view of the low efficiency of pedestrian crossing and the obvious conflict with turning vehicles at large signal control intersections, this paper carries out an in-depth investigation on pedestrian crossing behavior habits and analyzes the problems existing in pedestrian crossing. Based on the detailed design concept, this paper summarizes and refines the main design points of pedestrian twice crossing, discusses focusing on the combination of pedestrian phase and motor vehicle phase, and the right-turn vehicle “starting late”; Finally, taking the typical four-phase cross intersection as an example, using VISSIM software, the simulation analysis of the two situation of the current and optimization intersection is carried out. The results show that the pedestrian delay is obviously reduced without a significant increase in vehicle delay. This paper also verifies the rationality and feasibility of the pedestrian twice crossing improvement scheme based on the detailed design concept.
