BRT交叉路口主动优先自适应通行控制方法

针对BRT交叉路口优先控制方法逻辑单一、只注重减少车辆的延误、忽视对普通社会车辆的影响问题，提出了BRT交叉路口主动优先自适应通行控制方法.通过预测BRT车辆到达交叉路口停车线内时间，判断交叉路口的信号状态，依据交叉路口垂直方向的拥堵状态动态地调整控制策略，以决定优先控制策略是否执行.该方法注重BRT车辆的优先通行，提高了交叉路口的整体通行效率.Matlab仿真结果表明，采用主动优先自适应控制方法的BRT车辆的停车率明显低于定时控制方法，延误时间低于感应控制方法.

Research on Active Prioritizing Self-Adaptive Traffic Control Strategy of BRT Intersection

Currently,the priority control method in BRT intersection is simplex，which only focuses on reducing the time delays of vehicles but neglects the influence on general vehicles.Therefore,active prioritizing self-adaptive traffic control method of BRT intersection is put forward.The method not only focuses on prior traffic of BRT,but pays more attention to overall traffic efficiency in intersection.It can judge the signal condition of intersection through predicting the time that BRT vehicle reaches the parking line of the intersection.And it can adjust control strategy dynamically according to the jam situation in vertical direction to decide whether the priority control strategy should be executed.Simulation result shows that the stop rate of BRT vehicles by adopting active prioritizing adaptive control method is obviously lower than that of regular timing method,and time delay is also obviously lower than that of inductive control method.
