摘　　要：为研究信号交叉口交通流的运行特征,提高交叉口的通行能力,缓解交通拥堵,对车头时距的影响因素和分布特征进行分析。首先,根据车辆尺寸分为4种车型组合;然后,基于VISSIM仿真获取各类型车辆的车头时距数据,探讨不同车型组合、车辆转向和车道位置对车头时距的影响;最后,采用对数正态分布和韦布尔分布检验不同组合的车头时距数据的拟合效果,并检验模型的拟合优度。结果表明:根据不同车型组合,车头时距由大到小为大型车-大型车、大型车-小型车、小型车-大型车和小型车-小型车;根据不同车型组合下的转向,车头时距由大到小为左转、右转和直行;根据不同车型组合下的车道位置,车头时距由大到小为外侧车道、中间车道和内侧车道。The influencing factors and distribution characteristics of headway were analyzed,and the purpose is to study the operation characteristics of traffic flow at signalized intersections,improve the traffic capacity and alleviate traffic congestion.The research divides the vehicle into four types based on size.Then the headway data of each vehicle types were obtained based on VISSIM simulation.The influence of vehicle steering and lane position based on different vehicle types on headway was studied.Finally,log-normal distribution and Weibull distribution were used to test the fit of different types of headway,and to test the goodness of fit of the model.The results show that the headway of dfferent vehicle types from large to small are large car-large car,large car-small car,small car-large car and small car-small car.According to the vehicle steering,the headway of different vehicle types from large to small are left turn,right turn and straight.The headway of different vehicle types from large to small are the outside lane,the middle lane and the inside lane by the lane position.
