| 摘 要： | 头车疏解车距(The First Discharge Headway)是绿灯开始后到第一辆机动车启动并通过停车线的时间.本文分析了混合交通信号交叉口不同车道交通流的车型比例和干扰比例,结果表明,左转车道的小型车比例和受到的干扰次数高于直行车道.随后利用Logistic模型、Compertz模型、Logsitic模型分别... |

| Abstract: | The First Discharge Headway is the time consumed by the first car in the queue from its startup when the green light turns on to the second while it is completely across the stop line.This study analyzes the traffic composition and interference ratio of different lanes at the signalized intersection with mixed types of traffic flows.It is presented that left-turning lanes holds more small-sized vehicles and have much more interference.The functions of the first discharge headway of the left-turning lanes,in... |
