Multi-resolution traffic flow schemes, coupling microscopic (vehicle based), mesoscopic (cell based) and macroscopic (flow based) representations of traffic flow may be a useful tool to better understand and utilize the relationships between the various types of representation. The paper introduces some Multi-Resolution Modeling (MRM) approaches, the Wiedemann model and the VISSIM system. In addition, a mathematical model of meso-dynamic simulation of traffic flow is derived and then solved by using the numerical method of explicit upwind scheme. This paper designs the framework of Traffic Multi-Resolution Simulation System (TMRSS) using MRM theory and develops an integrated architecture among different simulation models. Next, the paper implements the hybrid scheme of both models using C++. Finally, simulation results show that the hybrid scheme can keep the results consistent between the meso-model and the Wiedemann model. It proves that the architecture and the mixed model are available in TMRSS.
