Question

随着社会经济的发展，城市交通问题越来越引起人们的关注。人、车、路三者关系的协调，已成为交通管理部门需要解决的重要问题之一。城市交通控制系统是用于城市交通数据监测、交通信号灯控制与交通疏导的计算机综合管理系统，它是现代城市交通监控指挥系统中最重要的组成部分。
交通信号灯是交通安全产品中的一个类别，是为了加强道路交通管理，减少交通事故的发生，提高道路使用效率，改善交通状况的一种重要工具。适用于十字、丁字等交叉路口，由道路交通信号控制机控制，指导车辆和行人安全有序地通行。
本文在介绍了单片机的基础知识之后，研究交通信号灯的控制设计方案，实现了交通信号灯的硬件设计，包括系统电源、时间显示电路、最小系统、交通灯电路、数码管示意图等。最后给出了系统框图和程序流程图。最终实现了交通信号灯的控制与研究。
问题补充：

（英文摘要翻译要符合ABC原则：A准确accuracy; B简练brevity; C清晰clarity）

Answer 1

With the social and economic development, urban transport problems are becoming increasingly a cause for concern. Of passengers, vehicles and the relationship between the way the coordination of traffic management has become an important need to address one of the issues. Urban traffic control system is used for urban traffic data monitoring, traffic signal control and traffic management computer system, it is the modern urban traffic control system command and the most important component.
Traffic lights is a safety product categories, is to enhance road traffic management and reduce the occurrence of traffic accidents and enhance road use efficiency and improve the traffic conditions of an important tool. Applicable to cross, such as T-intersection, from road traffic signal control machine control, guidance of vehicles and pedestrian traffic safety in an orderly manner.
This paper introduced the basic knowledge of SCM, the study of traffic signal control design, the realization of a traffic signal hardware design, including the system power, the time display circuit, the smallest system, the traffic light circuit diagram, such as digital control. Finally, the system flow chart diagram and procedures. The eventual realization of a traffic signal control and research.

Answer 2

Along with the social economy development, the municipal transportation question more and more arouses people's interest. The human, the vehicle, the road three relations coordination’s, have become one of important questions which the traffic control department needs to solve. The municipal transportation control system is uses in the municipal transportation data monitor, the street-traffic control lights control and the transportation unblocking computer synthesis management system management system; it is in the modern municipal transportation monitoring command system the most important constituent. The street-traffic control light are in a traffic safety product category, is in order to strengthen the road traffic management, reduces the traffic accident the occurrence, enhances the road usage efficiency, the improvement transportation condition one kind of important tool. Is suitable in the cross, the T-shape and so on the four corners, by the road traffic signal cyber Ron control, instructs the vehicles and the pedestrian safety order passes through. This article after introduced monolithic integrated circuit elementary knowledge, the research street-traffic control lights control design plan, has realized the street-traffic control lights hardware design, including system power source, time display circuit, smallest system, traffic light electric circuit, nixie tube schematic drawing and so on. Finally has given the system diagram and the program flow diagram. Finally has realized the street-traffic control lights control and the research.
