Embodiment 1

[0089] Such as figure 1 As shown, in this implementation, a regional traffic guidance method based on traffic identification and statistics at traffic intersections is disclosed, including the following steps:

[0090] Obtain the traffic road map of the target area, determine the key intersection set in the target area according to the impact of each intersection in the target area on the traffic in the target area, and the set of key intersections includes at least one key intersection;

[0091] Obtain the monitoring video data stream of each key intersection in the key intersection, identify and count the traffic flow data of each phase of each key intersection;

[0092] For any key intersection O: compare the traffic flow data of each lane of the key intersection O with its corresponding traffic flow threshold, and when it is judged that the traffic flow data of any lane of the key intersection O is greater than the corresponding traffic flow threshold, to alleviate the cri...

Embodiment 2

[0096] Embodiment two is a preferred embodiment of embodiment one, and its difference from embodiment one is that the specific steps of the regional traffic guidance method based on traffic intersection traffic identification and statistics are refined:

[0097] This embodiment discloses a regional traffic guidance method based on traffic flow recognition and statistics at traffic intersections, which can capture driving vehicles through high-definition video, set virtual coils in the video, and determine the driving conditions of the vehicles after analysis in the server. The principle of the virtual coil vehicle counting method is to set up one or more virtual detection lines on the lanes that need to be counted in the collected traffic flow video to detect the passing vehicles, so as to complete the counting of the traffic flow of the road section. The principle of setting the virtual detection line is generally to set a virtual line segment perpendicular to the lane line an...

Abstract

The invention discloses a regional traffic guidance method and system based on traffic intersection traffic flow identification and statistics. The method comprises the steps of: obtaining a traffic lane route map of a target region, and determining a key intersection set of the target region according to the traffic influence of each intersection in the target region on the target region; obtaining the monitoring video data flow of each key intersection in the key intersection set, and identifying and counting the traffic flow data of each phase of each key intersection; and for any key intersection O, comparing the traffic flow data of each lane of the key intersection O with a corresponding traffic flow threshold, and when judging that the traffic flow data of any lane of the key intersection O is greater than the corresponding traffic flow threshold, adjusting the traffic light signal of the key intersection O to relieve the traffic flow congestion of the key intersection O. By preferentially adjusting the congestion of the key intersection which has great influence on the traffic of the target region in the target region, the congestion in the region can be quickly and effectively adjusted.

Description

technical field [0001] The invention relates to the technical field of urban regional traffic guidance, in particular to a regional traffic guidance method and system based on traffic flow identification and statistics at traffic intersections. Background technique [0002] Urban transportation plays a vital role in social and economic development. With the rapid development of economy and the continuous improvement of people's living standards, private cars have become a means of transportation that can be used by every household. Its convenience and comfort have brought great benefits to people. Life is convenient, but it also brings problems such as traffic congestion. Traffic congestion restricts urban economic development and also affects people's road experience. [0003] In the traffic area, intersections of different locations or sizes have different impacts on regional traffic, while existing regional traffic guidance methods often ignore the different impacts of i...
