随着人们生活水平的日益提高,家庭轿车数量也在急速增长,给城市交通带来较大拥堵问题,尤其是各大中型城市纷纷采用限制单双号办法来缓解车流量,各个交通要道仍旧呈现出长时间堵塞现象。为了能够解决这一难题,本文首先介绍了智能控制红绿灯系统方案设计,然后从硬件和软件这两方面研究单片机智能红绿灯系统,证明该系统能够在很大程度上提高车辆在交叉路口通行的效率。 With the continuous improvement of people’s living standard, the number of family cars is also rapidly increasing, causing great congestion to urban transport. In particular, large and medium-sized cities have adopted restrictions on single and double numbers to ease the traffic flow and various traffic arteries are still Showing a long time blockage phenomenon. In order to solve this problem, this paper first introduces the intelligent control of the traffic light system design, and then from the hardware and software to study the single-chip intelligent traffic light system, which proves that the system can largely improve the efficiency of traffic at the intersection.
