摘要
在N aSch模型的基础上,考虑车辆长度,建立一维元胞自动机交通流模型。通过引入平均间距、占有率和启止密度等参数,数值模拟周期性边界条件下,车辆长度对路段交通流的影响。
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.
