The invention relates to the technical field of intelligent traffic, and discloses a vehicle path determination method and device, and a medium, and the method employs the real flow to reflect the real condition of a target road section, and supplements the traffic demand of vehicle missing detection or false detection. And constructing a traffic residual network according to the real physical connection between the road sections, the ID of the corresponding road section and the residual error between the real traffic and the current traffic, and calculating a gain according to the constructed network, so that when the gain is in a first state, a new path is generated by traversing the road sections to form an updated path set. And updating the traffic residual network by using the updated path set, circularly calculating gains until the gains are all in a second state, namely, when no new path is generated, determining the vehicle path information of the target road section. According to the scheme, the real situation of the target road section is reflected through the real flow, and the missed or false detected path is complemented by using the flow residual network, so that the traffic travel demand of the target road section is accurately reflected, and the accuracy of vehicle path determination is improved.

    本发明涉及智慧交通技术领域,公开了一种车辆路径的确定方法、设备、介质,该方法利用真实流量反应目标路段的真实情况,补充因车辆漏检或误检丢失的交通需求。以路段间的真实物理连接、对应路段ID以及真实流量与当前流量的残差,构建流量残余网络,并以构建的网络计算增益,从而在增益处于第一状态时,通过遍历路段生成新的路径形成更新路径集合。并以更新路径集合更新流量残余网络,循环计算增益,直至增益均处于第二状态,即无新的路径产生时,确定目标路段的车辆路径信息。本发明的方案通过真实流量反应目标路段的真实情况,利用流量残余网络补全漏检或误检的路径,从而准确反映目标路段的交通出行需求,提升车辆路径确定的准确性。
