Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Step 1: Arrange high-definition video units at signalized intersections with variable guiding lanes and upstream intersections, such as figure 1 shown;

[0028] Step 2: Take figure 1 , image 3 For example, based on the fact that the current driving direction of the variable guiding lane is the straight lane, the detection start time is taken as the starting time of the red light of the through traffic signal light on the entrance road, and one signal cycle is the detection cycle length.

[0029] combine figure 1 , image 3 , combined with the description of signal-controlled intersections with variable directional lanes in a city. The initial driving direction state of the variable steering lane at the intersection is preset as the straight lane, figure 1 L1=L2=30 meters, L=600 meters, intersection signal control cycle C=120 secon...

Abstract

The invention discloses an intelligent control method for changing the driving direction of a variable guiding lane at a signalized intersection, which belongs to the field of traffic control. Specifically, it includes the layout of two high-definition video units; the acquisition of parking times, control delays and signal control timing parameters; the intelligent decision-making method and process for changing the driving direction of the variable guiding lane. The present invention starts from the traffic characteristics of the variable guiding lanes at signalized intersections, and obtains the difference in the number of parking times of the traffic flows in each turning lane at the intersection through the high-definition video units installed at the entrance of the upstream intersection and the entrance of this intersection, and analyzes each The delay of turning traffic flow control is further judged, and an intelligent control method for changing direction of variable steering lane is proposed. The purpose of this method is to improve the traffic capacity of the entrance lane of the signalized intersection and the utilization rate of the variable guide lane, reduce the number of vehicles parking at the entrance lane, and reduce the delay of vehicles at the intersection.

Description

technical field [0001] The invention belongs to the field of traffic control at intersections, and in particular relates to an intelligent control method for changing the driving direction of a variable guiding lane at a signalized intersection. Background technique [0002] The driving direction of the channelized guide lanes on each entrance lane of the traditional signal-controlled intersection is usually set to a fixed driving direction, which cannot meet the needs of the obvious fluctuations in the turning flow of the intersection entrance lanes. The variable guide lanes just meet this vehicle traffic demand . At present, the change of the direction of the variable directional lane is often conducted by the police on duty to investigate the steering traffic volume and manually adjust the driving direction of the variable directional lane sign or set it in the driving direction change control device of the variable directional lane sign according to a fixed period of tim...
