Video detector-based bus signal priority control method

Abstract

The invention discloses a video detector-based bus signal priority control method and belongs to the technical field of intelligent traffic control. The video detector-based bus signal priority control method comprises the following steps: based on the video detector, performing signal priority identification of buses which enter the detection range; based on the video detector, performing operating parameter detection on the buses with signal priority and transmitting to an intersection signal machine; and performing priority control on the buses with signal priority according to the operating parameters of the buses with signal priority by the signal machine. The vehicle entering the detection range is subjected to priority identification by the video detector, the operating parameter of the buses with signal priority is acquired by the video detector, the operating parameter is transmitted to the intersection signal machine, and the signal machine controls the time of maintaining the current state of a signal lamp, so that control of the priority passing of the buses is realized, the passing efficiency of the buses is improved and traffic pressure is relieved.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a video detector-based priority control method for bus signals. Background technique [0002] Bus signal priority refers to giving priority to BRT vehicles at intersections to reduce the time for buses to pass through intersections, improve the overall operating efficiency of buses, and reduce delays per capita. [0003] The existing bus signal priority control method is to use the GPS positioning of the bus and transmit it to the intersection signal machine through wireless communication. City traffic jam. However, the existing bus signal priority control method has obvious defects: first, the location of the bus based on the bus GPS is inaccurate, and the signal transmitted by wireless communication is unstable and easily interfered, resulting in signal failure. Priority control results are inaccurate. Second, all priority vehicles for public transport need to be e...

However, the existing bus signal priority control method has obvious defects: first, the position positioning of the bus based on the bus GPS is not accurate, and the signal transmitted by wireless communication is unstable and easily interfered, resulting in signal failure. Priority control results are inaccurate

Second, all vehicles with priority on public transport need to be equipped with GPS positioning equipment, and the construction cost is relatively high
