| 摘 要： | 利用交通波理论研究了信号交叉口的停车次数模型。通过交叉口停车线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,并研究了不同聚集-释放模式与车辆停车次数的关系。针对三种模式中的稳定模式的车辆行驶轨迹作了分类,计算了其停车率,并对几种重要的停车率计算方法进行了比较分析。算例表明,传统停车率计算模型的估计结果总是偏大,且随着饱和度的变大对停车率的估计偏差也变大。这种偏差的根源在于其采用了点排队的假设。

| Abstract: | This paper study stops at signalized intersection using macroscopic traffic model.Through the analysis the start-wave and stop-wave in front of the stop line,it is concluded that the absolutely one-stop condition don't exist.And the relationship between accumulate-discharge mode and stop ratio is researched.Trajectory of vehicles is classed according to the stable condition and the stop ratio is studied.The designed numerical example shows that stop ratio model based on Stable Theory is always over estimate... |
