基于车速的自适应交通信号灯控制系统
A Self-adaptive Traffic Light Control System Based on Speed of Vehicles
摘要
Abstract
With the development of economy and the improvement of people’ s living standard,the number of vehicles in city is growing rapidly,and the congestion and environment pollution and other problems caused by traffic are becoming more serious. ITS ( Intelligent Transportation System) has become one of the hottest topics discussed by domestic and foreign researchers,and how to solve the traffic congestion problem is especially important in ITS. In order to improve traffic condition in intersections and to enhance traffic efficiency, a self-adaptive traffic light control system based on vehicle speed is proposed. It is an instance of V2I (Vehicle to Infrastructure) com-munication model,which realizes data transmission between vehicles and traffic light by using V2I protocols. Vehicles send speed messa-ges to the traffic light when passing the intersection,and the system controls by itself the traffic light by analyzing the speed of cars in both cross and the front and current state of the traffic light. This system can improve the traffic capacity and ease traffic congestion effec-tively through decreasing the congestion in intersection.关键词
