| 摘 要： | 通过交叉口停车先前停车波和启动波的分析,划分出车辆在信号控制下的聚集-释放模式,得出稳定输入下不存在完全一次排队。针对稳定模式中车辆行驶轨迹作了分类,并分别研究了它们各自的行程时间。并用算例表明,路段行程时间(即路阻)不仅是路段流量的增函数,同时它还会受到信号控制的影响。流量很低时的车辆行程时间有可能比流量高时的还要长。

| Abstract: | The vehicle accumulation-release mode under the signal control was differentiated through analysis of the start-wave and stop-wave of the vehicle behind the stop line,concluding that the absolutely one-stop queue condition does not exist under steady input.The trajectories of vehicles driving in steady mode were classified and their travel times were investigated respectively.The case calculation showed that the road travel time(or road resistance)is not simply an increasing function of the traffic flow,it ... |
