Signal Light Ptimization based on PTV Vissim Software

Abstract This paper conducts on-the-spot investigation on the traffic flow of each entry and exit road during the early peak period of the case intersection, and uses the data obtained from the survey to make accurate calculations to obtain the capacity and delay time of the current intersection, and then use PTV Vissim. The simulation software simulates the real-time road condition reduction simulation of this intersection.Finally, based on the results of the PTV Vissim simulation software, a more reasonable optimization plan for the traffic light duration configuration of the intersection is proposed, which can make the interlaced area smooth, fastest, and maximize travel efficiency. A new signal optimization solution based on PTV Vissim software can reduce the delay time of the intersection and improve its traffic capacity.
