摘要
车头时距是道路通行能力、交叉口交通控制及交通仿真等领域的基础。本文采用城市单车道车辆运行实测数据,研究了单车道车头时距分布特征,并利用χ2检验进行了单车道车头时距分布模型检验。
Vehicle headway is one of the foundations for highway capacity study, intersection control, traffic simulation, etc. In this paper, using the real world data collected for typical urban arterials, the vehicle headways are investigated and the distributions of the headways are tested using thex2 test approach.
