The invention discloses a bus trunk multi-intersection condition signal priority control method, which comprises the following steps of: firstly, determining an optimization target, namely improving the on-time performance of a BRT (Bus Remote Terminal) system and minimizing the adverse influence on private cars; secondly, a conditional TSP model is established, delay constraint, traffic priority time constraint and saturation and queuing length constraint are carried out on the vehicle, it is ensured that the vehicle arrives on time, and the relation between bus punctuality and private vehicle delay is balanced; thirdly, collecting data of motor vehicle flow demand, signal timing of an intersection, departure time of an upstream bus station and arrival time of a downstream bus station at the intersection of the check station and the station section; and finally, solving the model by adopting a mixed integer nonlinear programming method. According to the invention, the problem that the unexpected arrival time of the bus at the stop line of the continuous intersection affects the operation reliability of the bus rapid transit system is solved, the on-time performance of the bus rapid transit is improved, the adverse effect on private cars is minimized, and the operation efficiency of the whole traffic system is improved.
本发明公开了一种公交干线多交叉口条件信号优先控制方法,首先,确定优化目标,即改善BRT系统的准点表现和最小化对私家车的不利影响;其次,建立条件TSP模型,对车辆的延误约束、交通优先时间约束以及饱和度和排队长度约束,确保车辆按时到达,平衡公交车准点性和私家车延误的关系;再次,收集查站点与站点段交叉口的机动车流量需求、交叉口的信号配时、上游公交站离站时间和下游公交站到站时间数据;最后,采用混合整数非线性规划方法对模型求解。本发明解决了公交车辆在连续交叉口停车线的非预期到达时间影响快速公交系统运行可靠性的问题,提高了快速公交的准点表现,同时最小化对私家车的不利影响,提高了整体交通系统的运行效率。
