摘要: 基于Nagel-Schreckenberg交通流模型(简称NaSch模型),通过引入换道规则,建立包含非港湾式公交车站在内的双车道混合车辆元胞自动机交通流模型.计算机数值模拟表明,在周期边界条件下非港湾式公交车站路段的交通流存在一定的特性,在中等密度区域的拥挤流, 车辆的平均速度与车流密度存在一次幂律关系.Abstract: Basedon the Nagel-Schreckenberg traffic flow model, a cellularautomaton model of mixed traffic flow considering bus station ontwo-lane is proposed via introducing lane-change rule. Numericalsimulation indicate that the traffic flow in the bus stationswithout stopping-lane has a certain characteristics under thecondition of period boundary, that is to say, there is a power-lawscaling relationship between mean-velocity and density in thejamming phase over a medium density of vehicles.
