The detection and decision release of the dynamic dangerous area are the important research contents of intelli?gence road and intelligence infrastructure. To improve real?time supervise,safety early warning and emergency evacuation for transportation,and ensure a traffic safety stability,the broadband wireless connection is put forward to expand the way of the exis?ting fixed network video connection. The road disaster weather detection,data acquisition and event detection are carried out with video image processing and data mining technique to predict the traffic condition and the short time traffic flow in the dy?namic dangerous area,and then release the road net condition and the stability analysis. Through the experiment and testing re?sults of the system built in the expressway show that the system has good real?time performance,high detection accuracy,small error and better robustness. It improved the intelligence management of expressway.
