摘要
为了研究城市隧道出口处公交车的换道行为对交通流的影响,以城市隧道出口公交车的换道特性为研究对象,阐述并分析了公交车在城市隧道出口换道过程中的3种影响状态。然后采用摄像法采集相关数据并分析,借助SPSS软件构建了关于公交换道频率、公交换道持续时间、最大公交换道长度及其存在时间、隧道交通流量与车头时距关系的多元线性模型,并进行了相关性检验,得出了公交车换道对城市隧道出口交通流影响的主要因素。
To study the influence of bus lane-changing behavior at exit of urban tunnel on traffic flow, taking bus lane-changing behavior as the research object, 3 types of influence status during the bus lane-changing at exit of urban tunnel are described and analysed, and the data are collected by using TV camera and analysed. The multivariate linear models of the relation of time headway with the variables of the bus lane-changing frequency, bus lane-changing duration, the overall length of lane-changing as well as its reserve time and vehicle flow in tunnel is established applying the SPSS software. Then the correlation test are made, and the most critical influencing factors of bus lane-changing on the traffic flow at exit of urban tunnel are obtained.
