摘　　要：随着在世界各地交通拥堵现象日趋严重,城市内的交通信号智能控制变得越来越重要。先前研究的智能交通信号控制领域内有几个缺点,包括:依赖历史数据、固定配时、不能解决现实复杂多变的环境。文中提出的基于车流量的智能交通灯控制系统,利用视频检测技术,测得路口的实时车流信息,并依据所测得的信息设计了时间分配控制算法来调整控制各车道的绿灯时间,实时改变交通灯的时长以实现车流动态调节,该方案允许信号实时被更新以匹配当前的交通需求。运用到实际可达到缓解交通压力、提高通行效率、节省出行时间、节能减排、保护环境的目的。As traffic congestion rises within urban around the world,the intelligent control of traffic signals within cities is becoming in-creasingly important. Previous research for the area of intelligent traffic signal control has several shortcomings,including a reliance on historical data,fixing timing,not solving complicated and changeable situation. Propose the intelligent traffic lights control system based on traffic flow in this paper. It can get real-time traffic information with the help of video detection technology,and design the time algo-rithm that based on the information measured to adjust the control of the time of green light in all lanes,which can accurately change the time of traffic lights by achieving traffic dynamic adjustment. This solution allows signals to be updated frequently to match current traffic demand. It can alleviate traffic pressure,improve efficiency,save people＆#39;s time and energy and protect the environment.
