The invention provides a regional traffic flow induction method based on real-time traffic data and related equipment, and the method comprises the steps: obtaining the phase time length between two adjacent intersections for any two adjacent intersections in a plurality of intersections in a target region, taking one of the two adjacent intersections as a starting point intersection, and taking the other intersection as a terminal point intersection, determining the starting point intersection as an uplink intersection and the terminal point intersection as a downlink intersection according to the driving direction of the traffic flow from the starting point intersection to the terminal point intersection; according to the relation between the phase duration of the uplink intersection and the phase duration of the downlink intersection, the traffic flow saturation between the uplink intersection and the downlink intersection is calculated; the product of the distance between the uplink intersection and the downlink intersection and the traffic flow saturation is used as the path side length of the ant colony algorithm; the traffic flow of the target area is induced according to the path side length, and an induction result of the traffic flow of the target area is obtained; the efficiency and effectiveness of path induction are improved, and the traffic jam condition of the intersection is improved through effective induction.

    本发明提供了一种基于实时交通数据的区域车流诱导方法及相关设备,包括:分别针对目标区域内多个路口中的任意两个相邻路口,获取两个相邻路口之间的相位时长,以两个相邻路口中的一个路口为起点路口,另一个路口为终点路口,根据车流从起点路口往终点路口行驶的方向,确定起点路口为上行路口,终点路口为下行路口;根据上行路口的相位时长和下行路口的相位时长之间的关系,计算上行路口到下行路口之间车流饱和度;将上行路口与下行路口之间的距离与车流饱和度的乘积作为蚁群算法的路径边长;根据路径边长对目标区域的车流进行诱导,得到目标区域车流的诱导结果;提高了路径诱导的效率和有效性,通过有效诱导改善了路口交通堵塞情况。
