The quest continues for a cost-effective, reliable way to count the thousands of cars and trucks that cross the border between the U.S. and Mexico every day. Although counting vehicles may seem like an easy process, traffic counts are sometimes unreliable because of the stop-and-go environments typical at border crossings. In fiscal year 2013, researchers examined two products in their ongoing study examining the technologies best suited to measure traffic volumes in a border-crossing setting. One product being tested is a laser scanner that measures the distance from the device to the vehicle. Another product being studied is a pavement-mounted micro-radar inserted into a four-inch pavement core, about two inches deep. The radar unit faces traffic and is able to count the vehicles that pass by. A final report is being prepared on the products that have been tested. Researchers will include recommendations based on which products and technologies that worked the best. For more information contact Dan Middleton at (979) 317-2826 or [email protected].
