The invention provides a method and system for determining the traffic topology of a whole road section, electronic equipment and a storage medium, and relates to the technical field of intelligent traffic, and the method comprises the steps: building a road state database of a unified format at each intersection in a specified geographic area, and carrying out the flooding and interaction of the road state database between adjacent intersections, therefore, each intersection can master the regional road condition in real time. Then calculating a plurality of comprehensive traffic expenses corresponding to all selectable paths from the target intersection to each intersection in the specified geographic area, and processing the plurality of comprehensive traffic expenses by using a spanning tree algorithm to obtain a tree-shaped traffic topological graph taking the target intersection as a root node; according to the invention, each intersection in the specified geographic area can form an optimal path scheduling scheme according to the destination of the traffic participant, and meanwhile, the intersection traffic control equipment can dynamically schedule and command the traffic according to the road state database, so that the traffic flow is automatically subjected to load sharing, and the overall utilization rate of the traffic road is improved.
本发明提供了一种全路段交通拓扑的确定方法、系统、电子设备和存储介质,涉及智慧交通的技术领域,该方法在指定地理区域内的每个路口建立统一格式的道路状态数据库,且邻居路口间进行道路状态数据库的泛洪和交互,使得每个路口都能实时掌握区域路况。然后计算目标路口到指定地理区域内各个路口的所有可选路径对应的多个综合交通开销,并利用生成树算法对多个综合交通开销进行处理,得到以目标路口为根节点的树形交通拓扑图,基于此,指定地理区域内每一个路口都可以根据交通参与者的目的地,形成最优的路径调度方案,同时路口交管设备可以根据道路状态数据库动态地对交通进行调度指挥,使交通流量自动进行负载分担,提高了交通道路的整体利用率。
