Method for coordinating and controlling adjacent intersection signals of city by using video detection data

Abstract

The invention discloses a method for coordinating and controlling adjacent intersection signals of a city by using video detection data, relates to the method for coordinating and controlling the adjacent two intersection signals of the city, belongs to the field of signal control, and solves the problems of great coordination phase path traffic statistical error, inaccurate coordination and control scheme and the like caused by adopting induction coil detection data in the conventional signal coordinating and controlling method. The method comprises the following steps of: acquiring cross section images of stop lines of entrance lanes of each intersection by using a signal machine through a video detector; acquiring the number of vehicles according to the cross section images, and calculating traffic flow parameters according to the number of the vehicles; performing predicting calculation on the arrival traffic flow of each entrance lane; performing predicting calculation on the average operation speed of motor vehicles of a road section; calculating signal coordinating and controlling timing parameters; and acquiring a signal coordination and control scheme according to the signal coordinating and controlling timing parameters, and transmitting control signals to traffic signal lamps to realize the coordination and the control of signals. The method can be widely applied to the coordination and the control of the intersections of cities.

Description

technical field [0001] The invention relates to a signal coordination control method of two adjacent intersections in a city, belonging to the field of signal control. Background technique [0002] At present, the condition of traffic flow in major cities in our country is deteriorating day by day, which seriously hinders the development of social economy. Traffic signal coordination control technology, as a modern traffic management method, can effectively improve the operation efficiency of road network traffic flow and reduce vehicle delays. [0003] The essence of traffic signal coordinated control is to coordinate the traffic flow between adjacent intersections. Since the traffic flow of the coordinated phase is the main component of the traffic flow on the urban arterial road, it has the characteristics of large flow and dense traffic flow, so reducing the traffic delay of the coordinated phase can reduce the average delay of the traffic flow on the arterial road as a...
