The invention discloses a fixed-point flow guiding method in a traffic network. The fixed-point flow guiding method comprises the following steps: 1, constructing a topological structure, starting and ending places and places needing flow guiding of the traffic network; 2, calculating the shortest path from the starting point to the destination point to pass through the drainage point; 3, a disturbance strategy is obtained, so that the shortest path passing through the drainage point between the starting point and the ending point is the shortest path between the starting point and the ending point; 4, calculating a suboptimal path passing through the drainage point from the starting point to the destination point; and 5, obtaining a disturbance strategy to enable a suboptimal path passing through the drainage point between the starting and ending points to be the shortest path between the starting and ending points. According to the invention, fixed-point flow guidance in a traffic network can be realized, so that the flow in the network flows more biased, the flow can flow to a certain place in the network, and the passenger flow at the place is increased or a technical support is provided for optimization of the traffic flow.

    本发明公开了一种交通网络中的定点流量引导方法,包括:1构建交通网络的拓扑结构、起止地点以及需要流量引导的地点;2计算起始地点到目的地点经过引流点的最短路径;3获取扰动策略使得起止地点之间经过引流点的最短路径为起止地点之间的最短路径;4计算起始地点到目的点经过引流点的次优路径;5获取扰动策略使得起止地点之间经过引流点的次优路径为起止地点之间的最短路径。本发明能实现交通网络中的定点流量引导,使得网络中的流量更加有偏向的流动,从而能使得流量流向网络中某个地点,增加该地点的客流量或给交通流的优化提供技术支撑。
