AUTOMATED VIDEO-BASED SURVEY OF TRAVEL TIMES IN HOV VS. GENERAL PURPOSE LANES. FINAL TECHNICAL REPORT

Transformation Systems, Inc., was hired to perform automated video-based travel time surveys for the high occupancy vehicle (HOV) and the adjacent general purpose (GP) traffic lane on two freeway corridors in the Seattle area. The purpose of the project was to demonstrate and test the use of machine-vision technology for travel time data collection. Evaluating techniques for determining travel times and speeds is necessary for the Washington State Department of Transportation (WSDOT) to determine whether its HOV lane performance criteria are being met. The project used hi-8 video cameras to collect very-high quality videotapes of vehicle license plates. The videotapes were then processed at Computer Recognition Systems, Inc., in Cambridge, Massachusetts, with a specialized computer programmed to convert the video images into computer data files. The report details the video survey methodology; the data acquired through license plate recognition, including date, time, location, and direction of travel; and the comparison data used to determine respective travel times for HOV and GP traffic lanes.
