TRAFFIC FLOW VISUALIZATION AND CONTROL
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.
