Method for adjusting signal lamp time interval according to vehicle flow

Abstract

The invention relates to a method for adjusting a signal lamp time interval according to the vehicle flow and belongs to the intelligent traffic field. As signal lamp time intervals in the prior art are not reasonable, a problem that automatic regulation according to the vehicle flow can not be realized is solved through the method, pressure sensors and vehicle speed detectors are laid under a road surface in front of each traffic signal lamp crossing at 10-meter intervals, through data detected by the pressure sensors and the vehicle speed detectors, signal lamps are selectively adjusted according to a distance between a detection road and the crossing, time intervals of the traffic lamps are adjusted; the employed device is simple and convenient, cost is relatively low, automatic adjustment on the time interval of the signal lamps can be realized according to the vehicle flow, jamming time of the vehicles at the crossing can be reduced, the vehicle passing speed is improved, unblocked traffic is guaranteed, and convenient and rapid speed traffic is realized; through intelligent control on the signal lamp time, manpower and material resources for traffic guidance are saved, and automatic adjustment is realized.

Description

technical field [0001] The invention relates to a method for adjusting the duration interval of signal lamps according to traffic flow, and belongs to the field of intelligent transportation. Background technique [0002] In recent years, with the rapid development of motor vehicles, it has brought great pressure to urban traffic, so generally at intersections, it has become a "pass" in the traffic network and a "multiple source" of traffic accidents; in order to ensure traffic safety and prevent traffic Blocking, making urban traffic orderly, traffic lights have been widely used in most cities. [0003] However, the existing traffic lights are controlled according to the flow of people, which cannot meet the speed requirements of motor vehicles in urban traffic. They are usually blocked at a certain intersection, while the other intersection is unimpeded but there is no embarrassing situation for vehicles to pass. Therefore, a method that can control the duration of the si...

Problems solved by technology

[0004] The technical problem mainly solved by the present invention is: Aiming at the problem that the duration of signal lamps is unreasonable and cannot be self-regulated according to the traffic flow, a method for adjusting the duration of traffic signal lamps according to different traffic flows in different periods is provided, which reduces the Unnecessary waiting, avoiding vehicle congestion caused by the prescribed traffic signal time during peak traffic
