Numerical Simulation of Traffic Flow in the Rain or Snow Weather Condition

J.-Y. ZHAO, H.-B. ZHU, J.-B. GAO, L.-X. SHAO


Based on the NaSch model of traffic flow, a modified traffic model is proposed. The model attempted to reflect the drivers’ property of discreetness in the rain or snow weather condition by taking into account the special driving condition of wet, slippery road and poor visibility. The nonlinear properties of traffic flow in the rain or snow weather condition are analyzed thoroughly from the microcosmic viewpoint. And some meaningful conclusions are obtained
