Abstract

The invention relates to intelligent traffic, in particular to a congestion bottleneck point determination method and device, computer equipment and a storage medium. The method comprises the following steps of: acquiring road condition data of different time periods and a road network topological graph constructed based on the road network data; based on the road condition data, generating a road condition distribution map of each road section in the road network topological graph in different time periods, the road condition distribution map being used for reflecting whether each road section in the road network topological graph is congested or not in different time periods; in each road section of the road network topological graph, selecting a target road section which is congested in at least two time periods according to the road condition distribution map; determining a congestion contribution score of the target road section in a set of congested road sections in the road network topological graph; and determining a congestion bottleneck point based on the target road section of which the congestion contribution score reaches a preset condition. By adopting the method, the accuracy of determining the congestion bottleneck point can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, computer equipment and storage medium for determining congestion bottleneck points. Background technique [0002] Traffic congestion is an important topic of urban management. With the rapid increase of urban car ownership, the problem of urban traffic congestion is becoming more and more serious, and road congestion bottlenecks are the direct cause of traffic congestion. The traffic congestion in the area seriously affects the normal operation of urban traffic. Therefore, how to quickly and accurately find out the congestion bottlenecks in the road is a prerequisite for solving the traffic congestion problem. [0003] In the traditional technology, the location of the congestion bottleneck point in the road is mainly to judge whether there is a congested road section in the road according to the traffic condition data, and then use the congested ro...
