Reducing Truck Stops at High-Speed Isolated Traffic Signals

摘要

Border areas have seen a steady increase of truck traffic. This increase in trucktraffic causes an increase in pavement deterioration, which is amplified by trucks stopping at traffic signals. Reducing the number of stops made by trucks at high-speed rural intersections can significantly reduce delay and pavement damage. This project developed a truck priority logic and implemented it at an intersection in Sullivan City, Texas, to reduce truck stops. The project used a TCC 540 classifier and an industrical PC to implement this logic. The logic was developed with adequate safety features. Implementation of the truck priority logic indicated that there was a reduction in truck stops at the intersection.
