Abstract

The invention provides a traffic control method and system for an intersection, and relates to the technical field of traffic. The method comprises the steps of obtaining road condition information of an intersection; according to the road condition information, a preset intersection congestion evaluation index model is adopted to calculate and obtain the congestion index of the intersection; then matching the congestion indexes in a preset traffic condition grade table; searching in preset traffic control strategies according to the flow information in the road condition information and the matched traffic condition level to obtain a corresponding traffic control strategy; then, lane reminding information is extracted and generated according to shared lane switching information in the corresponding traffic control strategy; and finally, the lane reminding information is sent to a lane real-time display device to be displayed so as to remind vehicles to pass. Therefore, the problem that the intersection is easy to jam is effectively solved.

Description

technical field [0001] The present invention relates to the technical field of traffic, in particular, to a traffic control method and system for intersections. Background technique [0002] As an important part of the urban traffic system and the main place where traffic congestion occurs, the intersection is the bottleneck restricting the development of the urban traffic network. According to statistics, more than 80% of delays in urban traffic jams are concentrated at intersections. [0003] Present intersection generally adopts two-way straight-forward traffic, then turns left to two-way traffic, or adopts one-way right-turn, straight-going, left-turn traffic mode at the same time, no matter adopting any of the above-mentioned ways to pass through, it is all carried out in stages. [0004] At present, the traffic control of the intersection is to control the traffic lights according to the real-time road conditions of the intersection during use, so as to realize the dy...
