Embodiment Construction

[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0024] Such as figure 1 As shown, the mathematical model of the lane is established, and the horizontal and vertical distances of the lane are respectively set with squares at distances b and a. The horizontal direction of the lane is divided into 18 parts, and 19 grid points b1-b19 are taken. In this figure, the longitudinal direction of the lane is also taken as 19. The pressure sensor 1 will be described with each grid point. The pressure sensor 1 is a Bri...

Abstract

The invention relates to the field of intelligent traffic, in particular to a pressure sensor-based intelligent traffic control system. Multiple groups of sensor arrays are paved on a lane of an intersection; each group of sensor arrays comprises 64 pressure sensors which are distributed in an 8-row*8-line matrix; the transverse distance between the adjacent pressure sensors is b and the longitudinal distance between the adjacent pressure sensors is a; the distance from the sensor array to a white line on one side of the lane is 4b and the distance from the sensor array to a white line on the other side of the lane is 7b; the distance between the adjacent sensor arrays is 16a; a is 1.4b to 1.6b and b is 0.2m to 0.3m. The number of waiting vehicles on one lane can be detected by the pressure sensors paved on the lane and a signal lamp controller controls the passing time of traffic lights according to the number of the waiting vehicles on the each lane, so the circulating speed of the vehicles at the intersection is greatly increased and traffic pressure is relieved.

Description

technical field [0001] The invention relates to the field of intelligent traffic, in particular to a pressure sensor-based intelligent traffic control system that detects the number of vehicles on a lane by a pressure sensor to adjust the time of traffic lights to maximize vehicle mobility at intersections. Background technique [0002] With the continuous improvement of people's living standards, the per capita ownership of vehicles has increased significantly, and orderly traffic must have traffic control. It is imperative to give priority to the green light in the direction with more traffic and improve the traffic capacity of the road, so the intelligent traffic control device is very important. At present, statistical traffic control is practical, that is, to distinguish main roads and secondary arterial roads according to the average traffic volume in the north-south direction and east-west direction, adopt the principle of long green light time on main roads to set th...
