The invention relates to a traffic control method and system for multi-road resource optimization. The method comprises the following steps that the vehicle queuing length, the vehicle average speed and the vehicle position information of a certain intersection arecollected through a sensor, thereby calculating the road traffic capacity of the current intersection; a target function with the maximum road traffic capacity and the minimum average delay is constructed, and a preset target function value of a traffic phase sequence of each intersection is calculated, so that the optimal traffic phase sequence of the intersection is obtained and serves as the traffic phase sequence of the intersection in the next period; and the average delay is calculated according to the intersection passing phase sequence, the vehicle queuing length, the vehicle average speed and the vehicle position. Compared with the prior art, the congestion degree is reduced by reducing the vehicle input in the specific congestion area, so that the problem of traffic congestion is solved on the whole, the road condition is improved, and unmanned and intelligent traffic management is realized.

    本发明涉及一种多道路资源优化的交通控制方法和系统,方法包括以下步骤:通过传感器采集某一交叉口的车辆排队长度、车辆平均速度和车辆位置信息,从而计算当前交叉口的道路通行能力,构建以道路通行能力最大、平均延误最小的目标函数,计算预设的各个交叉口通行相位顺序的目标函数值,从而获取最优的交叉口通行相位顺序,作为下个周期该交叉口的交叉口通行相位顺序,所述平均延误根据交叉口通行相位顺序、车辆排队长度、车辆平均速度和车辆位置计算。与现有技术相比,本发明通过减少特定拥塞区域内的车辆输入来降低拥塞程度,从而从整体上解决交通拥塞的问题,改善路况,实现无人化和智慧化的交通管理。
