Research on Optimizing Intersection Signals Based on TRANSYT Single Timing Software

This paper aims to combine the use of both TRANSYT and VISSIM software in an attempt to reduce roadway traffic saturation while also combatting stop delay and queue lengths to improve the efficiency of traffic through an intersection. Investigation into and analysis of current conditions on Huang-Shan Road and Xiang-Zhang Avenue in Hefei city allows the TRANSYT and VISSIM models to be created and the two models to be compared. After using the TRANSYT model for signal optimization under two conditions, pedestrians are introduced. The model is combined with the VISSIM simulation software to verify the optimized results. The research shows that combining the software can reduce the road saturation effectively and reduce the both stop delay and queue length to improve the efficiency of the intersection.
