【Abstract】 Based on the NaSch model,a modified one-dimension cellular automaton traffic flow model is proposed by considering the vehicle’s length.By introducing the average gap,the occupation rate and the density of go-and-stop,the effect of vehicle’s length on road traffic flow is investigated through numerical simulation under the periodic boundary conditions.更多还原
