Abstract

The embodiments of the invention disclose a traffic flow peak identification method and device, electronic equipment and a storage medium which can improve the accuracy of the identification of a traffic flow peak period. The traffic flow peak identification method includes the following steps: obtaining traffic flow data in a current time period; according to the traffic flow data in the currenttime period, determining whether the traffic flow data in the current time period matches a time-varying mode corresponding to the peak time period through similarity calculation; and if the traffic flow data in the current time period matches the time-varying mode corresponding to the peak time period, determining that the current time period is a traffic flow peak time period. The traffic flow peak identification method and device, the electronic equipment and the storage medium of the invention are applicable to the identification of the traffic flow peak time period.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a traffic flow peak identification method, device, electronic equipment and storage medium. Background technique [0002] Traffic congestion usually occurs during peak hours of traffic flow. During peak hours, the vehicle operating environment is more complex, and there are more interference factors, resulting in a significant decrease in the stability of traffic operation. The duration of a road traffic flow peak period and the degree of traffic congestion during peak hours directly affect the service level and service capacity of the entire nearby traffic system. It can be said that traffic control during peak hours is the key to solving traffic congestion. In this scenario, the traffic flow peak recognition algorithm can realize peak calculation and real-time monitoring of urban roads and road networks, provide useful information for road condition release,...
