随着交通量的快速增长和缺乏对高速道路的系统研究和控制,高速道路没有充分发挥出预期的作用。而城市高速道路在构造上的特点,也决定了城市高速道路的交通状况必然受高速道路与普通道路耦合处交通状况的制约。所以,如何采用合适的控制方法,最大限度利用好耗费巨资修建的城市高速道路,缓解主干道与匝道、城区同周边地区的交通拥堵状况,越来越成为交通运输管理和城市规划部门亟待解决的主要问题。为此,通过我应用所学的知识设计了一套交通灯控制电路的方案。
With the rapid growth of traffic volume and the lack of systematic research and control over expressways, expressways have not fully exerted their expected functions. The structural features of the urban expressway also determine that the traffic conditions of urban expressway are bound by the traffic conditions at the junction of the expressway and ordinary road. Therefore, how to adopt appropriate control methods to maximize the use of heavily-funded urban high-speed roads and alleviate the traffic congestion in main roads and ramps and urban areas with the surrounding areas has become an increasingly urgent task for transportation management and urban planning departments The main problem. To this end, through my knowledge of the design of a traffic light control circuit program.
