The invention discloses a path selection method based on a gravitational field theory, belongs to the technical field of intelligent traffic systems, and particularly relates to the field of road network traffic efficiency optimization and node failure control. When traffic flow is transmitted in a traffic network, vehicles on nodes are subjected to the gravitational action of other nodes, and the gravitational force depends on the distance between the nodes, the congestion degree of the nodes and the medium centrality of the nodes. Under the thought, in each time step in the transmission process, all vehicles are subjected to the action of dynamically changing gravitational force, and the transmission path of the vehicles is also determined by a dynamically changing gravitational field. According to the path selection strategy based on the gravitational field provided by the method, the transmission of the traffic flow is controlled by adjusting a gravitational field mathematical model, the important nodes with the too high utilization rate can be avoided while the important nodes are effectively utilized, and the purposes of improving the transmission capacity and relieving the congestion condition are achieved.
该发明公开了一种基于引力场理论的路径选择方法，属于智能交通系统技术领域，特别是涉及路网通行效率优化及节点失效控制领域。在交通路网传递车流量时，节点上的车辆是受到其他节点的引力作用，这个引力大小取决于节点间的距离、节点的拥塞程度以及节点的介中心性。在这样的思想下，在传输过程中的每个时间步，所有车辆都受到动态变化的引力作用，其传递路径也由动态变化的引力场决定。本方法提出的基于引力场的路径选择策略通过调节引力场数学模型来控制交通流的传输，能够在重要节点得到有效利用的同时，避开利用率过高的重要节点，达到提高传输容量和缓解拥堵情况的目的。
