Abstract

The invention discloses a traffic flow detection method, belongs to the technical field of intelligent traffic, and solves the problem of inaccuracy in determining traffic flow under complex traffic conditions in the prior art. The method comprises the following steps: obtaining the road condition image of a traffic intersection; determining the value of a plurality of preset traffic flow influence factors according to the road condition image and / or the historical traffic data of the traffic intersection; determining the value of a principal component corresponding to the value of the plurality of preset traffic flow influence factors through at least one predetermined principal component expression; and inputting the value of the principal component corresponding to the value of a plurality of preset traffic flow influence factors into a pre-established traffic flow evaluation model and determining the traffic flow evaluation index of the traffic intersection so as to determine the traffic flow of the traffic intersection according to the traffic flow evaluation index, thereby contributing to improving the accuracy of obtaining the traffic flow of the traffic intersection under the complex traffic conditions.

Description

technical field [0001] The present application relates to the field of intelligent transportation, in particular to a traffic flow detection method, device, electronic equipment and computer-readable storage medium. Background technique [0002] With the increasing population and vehicle scale in cities, at traffic intersections with a large number of people and vehicles, it is necessary to control the switching time of traffic lights according to the traffic flow detection results to maintain normal traffic order. In the prior art, the acquisition of traffic flow mainly collects images of traffic intersections through image acquisition equipment, and then identifies and analyzes the people and vehicles in the images, and finally obtains the traffic flow in combination with the induction coil and laser speed measuring equipment set at the location of the traffic intersection. Traffic information such as the speed of vehicles at intersections, the number of vehicles, and the ...
