Urban Microscopic Traffic Simulation System and Its Application

An urban microscopic traffic simulation system was developed.It mainly involves vehicle generation model,network model,traffic regulation model,signal control model,vehicle action model,route choice model and intersection turning model.The system’s flowchart and every model’s modeling are illuminated.Aiming at urban traffic characteristic,a nearby car effect model was established as the supplement of traditional car following model.The three-dimensional visual part of this simulation system was realized on graphic workstation OCTANE.In the end,a typical road net was studied.
