摘要：	The TFVC system was developed in collaboration with the New York State Department of Transportation, the Federal Highway Administration, and the U.S. Air Force Research Laboratory. It is a video-camera-based, wide-area, traffic surveillance and detection system that provides real-time traffic information to traffic management center operators. The TFVC system uses a unique method of video sensing which automatically detects traffic patterns present in a captured traffic scene. This approach begins with a video image which is obtained from the output of an off-the-shelf video camera. Image processing algorithms verify traffic lanes and begin to extract traffic data, in real-time, from the live video. Vehicle count, flow speed, headway, queue length and occupancy are some of the information that can be collected. The processed traffic data is then sent to a control center for further analysis and used by traffic operators attempting to analyze traffic on the highway.
