Abstract: 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.

Key words: BRT；intersection, self-adaptation, active priority
