The traffic sign control needs to gain the scene volume of traffic information for the real-time control. Along with the image processing and video technique in vehicles automatic monitor aspect more and more applications, this article proposed one new traffic signal timing optimization method:based on CMOS of image sensor technology, the USB camera takes the scene photography and obtains the length of the vehicles that waiting for passing through image processing technology to optimize the real-time control of the signal lights.
针对交通信号配时的特点,设计了 S3C2410 为核心的嵌入式交通信号控制机 的电路,包括电源电路、USB 接口电路、各存储设备电路、调试必须的通信接口 电路。充分考虑到图像处理的实时性和准确性,采用剪裁的实用的 Linux2.4 内核, 制作根文件系统,开发应用程序,构建软硬件协作的嵌入式系统。
本次设计仅以简单的 2 相路口实验模拟实现优化配时,模拟实验表明该方法 应用方便可靠,可以有效改善交叉路口的通行能力,为优化城市交通控制提供了 一种参考方法。
交通信号控制器对交叉路口信号灯实时控制需要获取现场的交通量信息。基 于图象处理和视频技术在车辆自动监测方面越来越多的应用,本文提出了一种新 的交通信号配时优化方法:基于 CMOS 图像传感器技术的 USB 摄像头现场拍摄 图像,通过对图像处理提取城市交叉路口的车辆排队长度,据此进行信号优化实 时控制。

Abstract
智能交通灯控制系统的设计
It becomes more and more important that how to control transport system with modernization society developing. Intelligence Transport System (ITS) can improve traffic efficiency greatly as it use Information Technology, Communication Technology and Control Technology. The time-delaying problem of traffic can be solved with ITS very efficient and economical. In traffic sign control of crossroad, it is an important problem in urban transport system that how to design advanced scheme of traffic sign to improve control efficiency according to traffic character and queue rule of crossroad.
