基于转向交通流特性分析的变向车道设置应用

变向车道是当下解决交通流不均衡问题的重要措施。不同于以往单独分析各类型变向车道的设置,通过分析潮汐车道设置对左转车流的影响,及通过交通量、不均衡转向系数等指标分析左转车流的交通流特性,提出随相位变化的双停车线短变向车道。通过仿真分析,结果表明:随相位变化的变向车道设置,在有效时间内,提高了车流通行效率,减少了车辆在停车线前的等待。

The application of Variable Lane Setting Based on the Analysis of the Characteristics of the Traffic Flow

varible lane is the significant measure to resolve the imbalance problem of traffic flow.Different from the previous analysis of the various types of varible lane settings,Based on the analysis of the influence of the tidal Lane on the left turn traffic, and the traffic flow characteristics of the left turn traffic are analyzed by means of traffic volume and unbalanced steering coefficient.it proposes a short varible lane of double stop line with phase change.Through the simulation analysis, the results show that: with the change of phase to the lane setting, in the effective time, improve the traffic efficiency, reduce the vehicle waiting in front of the parking line.
