摘要
基于运行方向、环境、轨迹3个角度进行了车道变换行为的分类,按照意图产生、间隙选择、执行3个阶段划分了车道变换行为,分析了跟车调查和定点调查获取的实测数据,揭示了车道变换行为的时空分布特性。认为发生车道变换行为的时间间隔在1~2 min之间,不同车型发生车道变换行为的时间间隔有所不同;出入口相对于在直线段发生的车道变换行为更加频繁。
Based on the direction of running,environment and trajectory,the lane-changing characters were classified.In accordance with the three stages of lane-changing behavior including intent to produce,gap choice and implementation,the lane-changing behaviors were divided.The surveyed data were analyzed and the characteristis of the temporal and spatial distribution of lane-changing were revealed.It is concluded that the interval of lane-changing should between 1 and 2 minutes,and vary among different scales of vehicles,and that the lane-changing behaviors happen more frequently at intersections than along straight roads.
