摘 要

近年来随着科技的飞速发展，单片机的应用正在不断地走向深入。在实时检

测和自动控制的单片机应用系统中，单片机往往是作为一个核心部件来使用，仅

单片机方面知识是不够的，还应根据具体硬件结构，以及针对具体应用对象特点

的软件结合，加以完善。

本文首先对智能交通灯的研究意义和智能交通灯的研究现状进行了分析，指

application of MCU is going deeper. In the application of the automatic

control and detection of real time, the MCU is used to use as a key parts.

But if you want to design a system , only learn the knowledge of MCU is

insufficient . You should perfect the system on the basis of the structure

of the hardware and it is link to the characteristic of the application

object of the software.

First, in this paper, we discuss the studying significance and

studying situation of the Intelligent Transportation System(ITS) ,then

point out the drawback of the current situation and give the improve method.

Automatic Control is the most important function of the ITS. This paper
