Abstract

The invention provides a congestion identification method and device. The congestion identification method comprises the steps: acquiring the vehicle driving data, wherein the vehicle driving data indicates the vehicle traveling time of each vehicle passing through any one of at least one road segment to be identified within the preset statistical period, and the preset statistical period includesat least one day; determining the road state of each of at least one road segment to be identified in each day of the preset statistical period according to the vehicle driving data; determining theroad segment to be identified of which the road state is congested for more than the preset number of days in at least one road segment to be identified as the frequent congestion road segment and obtaining H frequent congestion road segments, wherein H is an integer greater than 1; and determining at least one frequent congestion trunk according to the H frequent congestion road segments.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a congestion recognition method and device. Background technique [0002] At present, the most prominent problem in urban traffic is traffic congestion, and traffic congestion in about two-thirds of the country's cities has become the norm. Alleviating traffic congestion is an important task of traffic police. In the process of relieving urban road traffic congestion, the traffic police mainly check historical videos and on-site investigations to determine the details of the scene and surrounding areas, and organize experienced traffic organization optimization, signal optimization and other experts to formulate congestion mitigation plans, and there is excessive reliance on experts Experience, long governance cycle and other issues. [0003] In the traditional traffic management system, when a road section is congested, it is often because there is no reminder to the ...
