The embodiment of the invention discloses a traffic network model construction method and device, equipment and a storage medium. The method is applied to the expressway, the expressway comprises tollstations, an interchange and a portal, the method comprises the steps: using a first directed graph for representing a traffic network model in the expressway, wherein the first directed graph comprises nodes and directed edges, the nodes comprise the toll stations and virtual stations, and the virtual stations are arranged in all road branches of the interchange, and the directed edge is a roadfor determining the passing direction between the nodes; determining a directed edge of the portal to be laid in the traffic network model as a target directed edge; calculating the complexity of thetarget directed edge, wherein the complexity is the access degree of the road section where the target directed edge is located; and if the complexity is greater than a preset threshold, adding a portal in the target directed edge. The portal layout scheme determined based on the traffic network model is realized, and the working reliability of the portal is improved, so that the accuracy of identifying the vehicle driving path is improved.

    本发明实施例公开了一种交通网络模型的构建方法、装置、设备和存储介质。该方法应用于高速公路,高速公路包括收费站、互通立交、门架,方法包括:以第一有向图表示高速公路中的交通网络模型,第一有向图包括节点和有向边,节点包括收费站、虚拟站,虚拟站设置在互通立交的各道路分支中,有向边为节点之间确定通行方向的道路;确定待布设的门架在交通网络模型中的有向边,作为目标有向边;计算目标有向边的复杂度,复杂度为目标有向边所在的路段的通达程度;若复杂度大于预设的阈值,则在目标有向边中增设门架。实现基于交通网络模型所确定的门架的布设方案,提高门架的工作的可靠性,从而提高识别车辆行驶路径的准确性。
