Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0022] According to one aspect of the present invention, a method and device for adaptive control of urban traffic signals based on single video are provided, such as figure 1 As shown, the traffic signal control device includes a video acquisition device V and a traffic signal controller C, wherein: the video acquisition device V can be installed at any position at the intersection, and its requirement is to set the vehicle flow direction in the conflict area inside the intersection Detection point, which should try to include the vehicle trajectories in each release direction, and detect the movement of vehicles in the conflict area inside the intersection in real time through video. The video detection equipment is ins...

Abstract

The invention discloses an urban road intersection self-adaption control method based on single video. According to the method disclosed by the invention, a vehicle flow direction detection point position of a conflict area in an intersection is arranged according to intersection environment and actual installation position of video detection equipment, and the point position contains vehicle movement tracks in all the release directions; video collection equipment is used for detecting outlines and movement states of vehicles in a detection area and performing statistics on traffic flow; a phase position release mode, the maximum green light, the minimum green light and a phase position switching speed are designed according to site situations; traffic signals are controlled according tomovement situations detected by the video detection equipment of vehicles in the area in the intersection. The method can effectively reduce construction cost of the intersection, improves urban intersection traffic efficiency and achieves the purpose of relieving traffic jam.

Description

technical field [0001] The invention relates to the field of urban intelligent traffic control, in particular to an adaptive control method and device for urban road intersections based on single video. Background technique [0002] Currently widely used single intersection control mainly includes timing control, induction control and adaptive control. Among them, induction control and adaptive control rely on induction coils, geomagnetism or video detection equipment arranged behind the stop line at the intersection. Its construction cost and maintenance cost are extremely high, and the installation and deployment of equipment and facilities and algorithm operation are complicated, so there are many deficiencies in the current urban traffic control application. Therefore, reducing construction and maintenance costs and improving the stability and ease of use of equipment and algorithms are also important measures to alleviate urban traffic congestion. Contents of the inv...
