摘 要 近年来随着社会的快速发展和人们生活水平的不断提高，城市交通的车流量大幅度增加，给交通道路的运行带来了巨大的压力。在复杂的城市交通控制系统中，单交叉路口交通控制系统通常采用的方法是定时控制方案，预先人为地分配好红黄绿灯的保持时间。其主要目的是协调好车辆的通行,尽量减少车辆的延误和道路的拥挤。为了能更好更快地解决城市交通道路拥挤的问题，特别是对交通灯的控制要求就很高。因此本课题选择模糊控制算法来实现交通灯对交叉路口的智能控制。
本文首先介绍模糊控制的相关内容，利用模糊控制算法设计了单路口红绿灯模糊控制器，研究对交通灯的控制的模糊控制算法，并利用仿真将模糊控制的效果与定时控制的效果进行比较。使用MATLAB仿真结果表明：利用模糊控制算法来实现对交通灯的控制，其效果优于定时控制。

ABSTRACT
In recent years along with society's fast development and the people living standard's unceasing enhancement, municipal transportation's traffic flow magnitude increased large scale, has brought the huge pressure for the transportation path's movement. In the complex municipal transportation control system, the method which the list four corners traffic control system usually uses is the timed control plan, artificial assigns the good red yellow green light maintains the time in advance. Its main purpose is coordinated the good vehicles passing through, reduces vehicles' delay and path's crowded as far as possible. For can better solve the municipal transportation road congestion quickly the question, the control request is very specially high to the traffic light. Therefore this topic choice fuzzy control algorithm realizes the traffic light to the four corners intelligent control.
This article first introduced that the fuzzy control the related content, the use fuzzy control algorithm design single-channel lipstick green light fuzzy controller, has studied to the traffic light the control fuzzy control algorithm, and carries on using the simulation fuzzy control's effect with the timed control effect the comparison. Uses the MATLAB simulation result to indicate: Uses the fuzzy control algorithm to realize to the traffic light the control, its effect surpasses the timed control.
Key words: Single-junction traffic lights，Fuzzy Control，Simulation，MATLAB
