摘要
快速路交织区车辆换道行为研究对于剖析交织区交通流冲突及驾驶行为特性具有重要意义。本文通过建立车辆换道冲突模型,利用车辆轨迹提取软件提取车辆换道轨迹并计算得到了336组避险时间和233组碰撞时间,运用统计分析的方法对快速路交织区车辆运行特性和换道过程进行分析,将换道冲突分为4个等级,并提出了交织区车辆换道的合理建议和管理措施。研究成果将有助于进一步完善道路通行行为研究体系。
The study of lane changing behavior in expressway weaving area is of great significance to the analysis of the traffic flow conflict and driving behavior characteristics. In this paper, a lane changing conflict model was established and trajectory extraction software was used to extract and calculate TTA（time to avoidance） and TTC（time to collision）. We got 336 TTAs and 233 TTCs and 4 grades of the lane changing conflict level were built by using statistical method. We came up with the proposed lane changing speed and some traffic management strategies. The study will help to further improve road traffic behavior research system.
