[0075] like figure 1 As shown, in a modern city, the urban road network extends in all directions. If the intersections are regarded as nodes, and the roads connecting different intersections are regarded as edges connecting different nodes, the entire road network can be regarded as a mathematical graph. , it should be noted that the intersection mentioned here can be a T-shaped (three-forked) intersection, a cross (four-forked) intersection, a five-forked intersection, etc., as well as a circular roundabout. The road mentioned here refers to the road that vehicles pass through. The directionality of vehicles on the road, so the road has one-way driving lanes and two-way driving lanes, so figure 1 is actually a directed graph.
[0076] A method for grading and sorting the importance of roads by time period in an urban road network, comprising the following steps:
[0077] S1. Establish a directed graph model of the urban road network: turn the edges representing roads into ...
