A Mesoscopic Traffic Simulation Model and Its Case Applications

Traffic simulation models can be divided into three classes-macroscopic,mesoscopic and microscopic simulation models.A mesoscopic traffic simulation model has both the positives of a macroscopic and a microscopic model.Relevant domestic research on a mesoscopic model is still quite rare.We apply a mesoscopic model,DynaCHINA,to intelligent transportation based on its principle and functionalities and analyze some application cases.Actual road network tests show that this model can effectively reduce the average travel delay of a vehicle in a road network and can be extended to applications in more complex road networks.
