引言：许多交通灯系统的控制都是通过改变显示时间及交通灯变换的时间间隔来达到控制交通的目的。一种智能的交通灯控制系统通过传感器来感知交通流量的大小来控制交通信号显示系统。设计这种智能交通灯的想法是为了使司机不用花费太多的时间去等待交通灯的变化，并且这种智能交通灯能够检测出不同的交通状况。

旧的交通控制系统广泛应用的是一种触发机制，目前的交通灯系统都是用固定的控制方法来控制交通灯的变化，为了要做到这一点，则要通过算法来实现对交通系统的控制。虽然当今有很多种编程语言，但一些编程语言普遍还是应用布尔逻辑来实现的.

我们要明白交通信号的作用，它使我们有一个好的驾驶习惯，通过限制速度，来保障我们的行驶安全，降低交通事故的发生。现在的司机都知道交通灯的工作原理，这使得他们在交通灯还没有变化时就急不可待的行驶了。智能交通灯的设计和开发的主要目的就是减少每辆车的等待时间，应用最合理的、最科学的.......

Abstract: The main object of this study was to design and implement a suitable algorithm and its simulation for an intelligent traffic signal simulator. The system developed is able to sense the presence or absence of vehicles within certain range by setting the appropriate duration for the traffic signals to react accordingly. By employing mathematical functions to calculate the appropriate timing for the green signal to illuminate, the system can help to solve the problem of traffic congestion. The simulation of the algorithm of the traffic signal system was done using MATLAB software. Hardware simulation tests were successfully performed on the algorithm implemented into a controller. The new timing scheme that was implemented promises an improvement in the current traffic light system and this system is feasible, affordable and ready to be implemented especially during peak hours. A countdown timer interfacing according to the traffic system using Lab VIEW software was also created. Key words: Traffic signal system, sensor based traffic light system, traffic congestion

INTRODUCTION

Many traffic light systems operate on a timing mechanism that changes the lights after a given interval. An intelligent traffic light system senses the presence or absence of vehicles and reacts accordingly. The idea behind intelligent traffic systems is that drivers will not spend unnecessary time waiting for the traffic lights to change. An intelligent traffic system detects traffic in many different ways [1]. The older system uses weight as a trigger mechanism [2]. Current traffic systems react to motion to trigger the light changes. Once the infrared object detector picks up the presence of a car, a switch causes the lights to change. In order to accomplish this, algorithms are used to govern the actions of the traffic system. While there are many different programming languages today, some programming concepts are universal in Boolean Logic. We need to understand the function of traffic signals so that we can improve driving habits by controlling the speed in order to reduce the number of associated traffic accidents. The more number of drivers who know about the operation of traffic signals, the less frustrated they are going to be while waiting for the lights to change. The main aim in designing and developing of the Intelligent Traffic Signal Simulator is to reduce the waiting time of each lane of the cars and also to maximize the total number of cars that can cross an intersection given the mathematical function to.......
