摘要:
 现有的交通灯控制系统主要考虑固定轮转次序下红绿灯的持续时间，但随着交通状况的日益复杂，原有的控制系统已不能对复杂路况进行很好的应对。为了提高控制系统的实时适应性，文中提出了一种基于无线传感网的智能交通灯自适应算法，根据各预设的地磁传感节点采集到的数据，综合考量各路口的状态需求，以此对路况进行智能的反馈控制(红绿灯轮转顺序，绿灯时长)。实验结果表明，相较于模糊控制和固定控制(固定轮转次序和时长)算法，该算法在诸如车流量以及平均等待时间方面有较大的改善。
Abstract:
 The existing traffic light control systems mainly focus on the red/green light duration in a fixed cycle. While with the increasing complexity of the traffic situation,the current control systems have been unable to perform well. In order to improve the performance of real-time control system,propose an adaptive traffic light control algorithm based on wireless sensor networks,which takes consideration of requirements for each intersection in roads comprehensively. According to the date collected by pre-installed magnetic nodes,the traffic light will make intelligent responses and decisions,such as the green rotation sequence and the light duration. The experimental results show that compared with the fuzzy logic and fixed-cycle control algorithms which has a const green light duration or a fixed cycle,the proposed one obtains more satisfactory performance on traffic flow and waiting time.
