| description | A road network key road section identification method comprises the steps of: (1) constructing road section importance information particles, specifically, obtaining importance values of all road sections in a road network in all time periods through calculation based on a road section importance evaluation method in existing achievement, taking a certain quantile value of the importance degree ofeach road section in a certain time period as a threshold value for judging whether the road section in the time period is a key road section or not, and taking an interval formed by the threshold value and the maximum value of the importance degree of each road section as an information particle of the importance degree of the road section in the time period; (2) preliminarily judging key road sections in the road network, namely preliminarily identifying key road sections in the road network by judging whether the importance values of the road sections are in an information particle interval or not; and in a certai |
