摘要
为了实时估计路段车辆排队长度,利用铺设在路段上的检测器,提出了一种车辆排队估计方法,对车辆排队进行实时跟踪。该方法考虑了一般的道路拓扑结构,路段排队的演化过程分为四个阶段:初始排队阶段、排队蔓延阶段、排队上溯阶段和堵塞路段阶段,不同阶段的排队利用不同的信息,通过不同的模型进行推算,通过实地调查验证,可以高效实时追踪路段排队的演化。
In order to estimate real-time queue length and provide information for traffic management,an algorithm was proposed.This method uses detector lay under road surface to track vehicle queue.General road topology was considered.Queue evolution was divided into four stages： initial queue stage,queue propagation stage,queue spillover stage,and fully congested stage.Different information was used to estimate queue length in different stages.The field test proves the effectiveness of the method.
