摘要
交通控制系统是近现代社会随着物流、出行等交通发展产生的一套独特的 公共管理系统。要保证高效安全的交通秩序，除了制定一系列的交通规则，还必 须通过一定的科技手段加以实现。本文在对目前交通控制进行深入分析的基础 上，运用检测传感、实时调整智能化控制的实现技术，将传感器监测、实时调整 车辆通行时间的算法与单片机控制作用相结合，提出了基于单片机的交通控制系 统设计方案。
十字路口车辆穿梭，行人熙攘，车行车道，人行人道，有条不紊。那么靠 什么来实现这井然秩序呢？靠的就是交通信号灯的自动指挥系统。单片机的交通 灯控制系统由STC89C52单片机、交通灯显示、LED倒计时、紧急处理、时间模 式手动设置等模块组成。系统除基本交通灯功能外，还具有通行时间手动设置、 可倒计时显示、急车强行通过、交通异常状况判别及处理等相关功能。理论证明 该系统能够简单、经济、有效地疏导交通，提高交通路口的通行能力。
本设计主要做了如下几方面的工作：一是确定系统交通控制的总体设计，包 括，十字路口具体的通行禁行方案设计以及系统应拥有的各项功能，二是硬件电 路、显示电路等的设计和基本功能要求。三是进行软件系统的设计。对于本系统, 本人采用单片机C语言编写，总体上完成了软件的编写。

ABSTRACT
Traffic control system is a modern society with the logistics, travel and other transportation development of a unique set of public management system. To ensure safe and efficient traffic order, in addition to the development of a series of traffic rules, it must be through some technological means to achieve. In this paper, the current traffic control for in-depth analysis, based on the use of detection sensors, real-time adjustment to achieve intelligent control technology, sensor monitoring, real-time adjustments to traffic control algorithm and the role of single-chip combination is proposed based on microcontroller traffic control system design.
Crossroads shuttle vehicles, pedestrians bustling, car dealers Drive, people walkways, orderly. Then rely on to achieve the discipline of the order then? Rely on the automatic traffic light is the chain of by the traffic light control system 8051, traffic light display, LED countdown, traffic detection and adjustment, compliance testing, emergency treatment, time mode manually set the other modules. In addition to basic traffic light system functions, but also with the passage of time manually set, you can countdown show, emergency vehicle forced through, traffic detection and adjustment, identification and handling of traffic anomalies and other related functions. The system is able to prove the theory is simple, economic, effici
