基于车流量的交通信号灯实时控制的研究

道路交通信号灯控制与道路交通标志线的设置共同组成了对道路交通控制和管理的一个完整部分。交通信号灯控制在整个道路交通工程中起到了重要的作用,它主要应用于交通量较大、交通流冲突较多和复杂的交叉路口,以及某些道路路段上需要对交通流方向控制的地方。针对现有的交通信号灯控制中的一些缺陷,本文提出一种利用交通路口中车辆数量为引导因素,利用VC++编写信号灯实时控制程序,以达到对交通信号灯的实时控制。

Research on Real-time Control of Traffic Lights Based on Traffic Flow

The control of road traffic lights and road traffic signs line set together to form an integral part of road traffic control and management.Traffic signal control has played an important role in the entire road traffic engineering,it is mainly used in traffic volume,traffic flow more conflict and complex intersections,as well as control the direction of traffic flow on certain road sections.For a number of deficiencies in the existing traffic signal control,a number of vehicles in the traffic junctions to guide the factors,the use of VC＋ ＋ to write semaphores real-time control program,in order to achieve real-time control of traffic lights.
