Intelligent traffic signal control system

Abstract

The invention discloses an intelligent traffic signal control system based on a high-definition video technology. The system comprises three parts, namely out-station equipment, a communication network and central system equipment, wherein the out-station equipment takes a single intersection as a unit, each direction of each intersection is provided with a high-definition camera; each camera is connected with a high-definition video detection host to be arranged in a signal case; a signal lamp is accessed in a traffic signal controller and is communicated with a central system through a network device in an intersection signal machine; the communication network contains three parts, namely network connection between each intersection signal machine to a signal control communication unit, a communication unit and internal network connection of the central system equipment; and according to function, the central system equipment is divided into the following four types: traffic signal control system equipment, traffic violation processing system equipment, traffic video monitoring system equipment and an operating terminal. As the high-definition video technology is utilized in the invention, the detection of dynamic traffic flow data can be realized, and the functions of traffic data acquisition and traffic enforcement can be realized.

Description

technical field [0001] The invention relates to the field of road traffic signal control and the field of high-definition video detection. Background technique [0002] With the continuous development of my country's economy and society, urban road traffic is basically in a saturated state. Road congestion and the resulting environmental pollution, low efficiency of urban operation, and traffic accidents have become bottlenecks restricting urban economic and social development. As an effective means to solve the problem of urban traffic congestion, many cities in China have introduced intelligent traffic signal control systems, such as the British SCOOT system, the Australian SCATS system, the American ACTRA system, the Spanish SANCO system, and the Hisense HSC system. Existing traffic signal control systems all use induction coils as vehicle detectors, but coil vehicle detectors generally have shortcomings such as easy damage, high maintenance costs, and limited measurement...
