Analysis of an intersection based on active priority strategies

Abstract

This paper focuses on the effect of active priority strategies (APS) in reducing the delay of the bus in the intersection. The research focuses on a typical intersection of Nanjing in China and VISSIM is used to build the model with data collected from the scene. Delay and travel time between two detectors are used to evaluate the effectiveness of the strategy. Besides, the operation effects of social vehicles and buses in current signal timing and two optimized plans programed in Vehicle Actuated Programming (VAP) module of VISSIM are contrasted. It turns out that APS can reduce the average delay and travel time per person greatly and improve the operation efficiency of vehicles in an intersection.
