The invention relates to a traffic distribution method, device and equipment based on strategy flow and a readable storage medium. The method comprises the steps of: acquiring a traffic network model and a plurality of user travel demands, establishing a plurality of initialized super path trees and a plurality of super clusters, expanding the super clusters, adjusting the super clusters and outputting a hypergraph. The costs of a plurality of super paths between OD pairs on the traffic network model are made to be the same by continuously adjusting the flow on each super road section, and a hypergraph containing all super road sections in all the OD pairs on the traffic network model and the flow on the super road sections is output to predict the pedestrian flow of each road section in an existing traffic network in advance, so that optimal layout can be conveniently carried out on related roads in advance. Meanwhile, the cost of the super road sections and the node cost can be adjusted according to a specific traffic network system, so that the traffic distribution method based on the strategy flow is suitable for flow distribution problems of various different traffic networks, namely, has the function of explaining the flow distribution problems of a general traffic system.
本发明涉及基于策略流的交通分配方法、装置、设备及可读存储介质,包括获取交通网络模型和多个用户出行需求、建立多个初始化超路径树并建立多个超丛、扩展超丛并对超丛进行调整和输出超图,通过不断调整各个超路段上的流量使交通网络模型上的每个OD对之间的多条超路径的成本相同,并输出包含有交通网络模型上所有OD对中的所有超路段以及超路段上的流量的超图,用于提前预测现有交通网络中的各路段人流量,便于提前在相关道路上进行优化布局;同时由于超路段的成本和节点成本可根据具体的交通网络系统进行调整,因此该基于策略流的交通分配方法克适用于多种不同交通网络的流量分配问题即具有对一般性的交通系统流量分配问题进行阐述的功能。
