The invention provides a multi-mode traffic network over-path flow distribution method, device and equipment and a medium, and relates to the technical field of traffic flow distribution, and the method comprises the steps: obtaining road network information; constructing a multi-mode traffic network by using the road network information, wherein the multi-mode traffic network comprises a plurality of OD pairs; constructing a balanced distribution model about a multi-mode traffic network according to the road network information; calculating a super path set of each OD pair and a relative error corresponding to the super path set; when a balanced distribution model is satisfied, a multi-mode distribution algorithm is adopted to distribute flow for each super path in all super path sets in the multi-mode traffic network, and a relative error is calculated in real time according to the distributed flow until the relative error corresponding to each super path set is smaller than a preset error; the method is used for solving the technical problem that a distribution model in the prior art lacks a path selection behavior and is difficult to adapt to a large-scale traffic network.
本发明提供了一种多模式交通网络超路径流量分配方法、装置、设备及介质,涉及交通流量分配技术领域,包括获取道路网络信息;利用所述道路网络信息构造多模式交通网络,所述多模式交通网络中包含若干个OD对;根据所述道路网络信息构建关于多模式交通网络的均衡分配模型;计算每个OD对的超路径集和所述超路径集对应的相对误差;在满足均衡分配模型下,采用多模式分配算法为所述多模式交通网络中的所有超路径集中的每条超路径分配流量,根据分配的流量实时计算相对误差,直到每个超路径集对应的相对误差小于预设误差,本发明用于解决现有技术中的分配模型缺乏考虑路径选择行为,难以适用于大规模交通网络的技术问题。
