中文摘要：

视频检测作为智能交通中一种主要的检测手段在交通流检测、车辆违章跟踪等领域得到了广泛的研究和发展。文中提出了一种城市道路交通灯智能控制模型，该模型利用视频图像处理技术，获取十字路口各方向的车流量参数、违章车辆信息等，在此基础上实现了交通灯的智能控制以及对违章车辆的视频跟踪，最后给出了实际交通视频图像处理的实验结果。

英文摘要：

As aprimarymethod for intelligent transportation system （ITS） , video detection is extensively studied and developed, and is also widely applied in the field of traffic flows detection and illegal traffic tracking. In this paper, a city traffic-light intelligent control model is proposed. Based on this model, the parameters of video traffic flows and the illegal traffic information in every direction of the crossroad are acquired first by using video image processing technique, then the intelligent control of the traffic lights and the illegal vehicle tracking. Finally, the experimental results of the real traffic video processing are provided in this paper.
