Embodiment Construction

[0051] The turn in the following embodiments refers to a left turn.

[0052] see figure 1 Shown, be a kind of traffic control method based on video tracking and variable lane of an embodiment of the present invention, comprise the steps:

[0053] S1: Set a variable lane backwards from the stop line of the straight lane on a straight lane directly adjacent to the turning lane.

[0054] S2: Set a variable lane stop line at the entry position of the straight vehicle on the through lane with the variable lane; set a variable lane near the variable lane stop line on the turn-only lane entrance.

[0055] S3: Avoid the entrance of the variable lane on the turn-only lane and set a no-parking area with at least one parking space length adjacent to the entrance near the intersection; the setting of the no-parking area, on the one hand, ensures the entrance Not occupied; at the same time, when the turning green light of the variable lane is turned, the turning vehicle is guided to con...

Abstract

The traffic control method and control system based on video tracking and variable lanes of the present invention can accurately control the start and close of turning or straight green lights in the main indicator lights by tracking the departure of vehicles entering the variable lanes before the change in real time, That is to ensure the green light time required for vehicles entering the variable lane to safely leave before the function of the variable lane changes, clear the vehicles on the variable lane in time, and will not interfere with the normal passage of vehicles in the subsequent signal cycle; Before the lane change function changes, the vehicle that enters the changeable lane will change the indication of the main indicator light immediately after the safe departure. capacity.

Description

technical field [0001] The invention relates to the field of traffic control, in particular to a traffic control method and control system based on video tracking and variable lanes. Background technique [0002] With the increase of motor vehicles, the existing road resources are becoming more and more tense, and congestion often occurs, which greatly affects the travel efficiency of residents. Therefore, how to make full use of existing road resources through reasonable channelization and control has become the focus and difficulty in the field of traffic control. [0003] Chinese patent document CN102938204A discloses a control method for changing the steering function of a variable guiding lane at an urban intersection, which specifically includes: detection of traffic flow occupancy; discrimination of changing of the steering function of the variable guiding lane; moment of turning change of the variable guiding lane Selection; Calculation of clearing time of variable ...
