TRUCKS MAY GET THE GREEN LIGHT IN SOUTH TEXAS

A major cause of pavement damage at intersections is the abrupt stops of heavy trucks at traffic lights. Researchers have found a solution in a device that detects heavy trucks at intersections and allows them to pass through lights without having to stop. Researchers selected an acoustic sensor and an infrared detector to test as the most appropriate truck detector. They also developed software that interfaces with the traffic signal controller and collects performance comparisons. The cost of the infrared system was approximately $10,000 for one lane of detection, and the cost of the acoustic system was approximately $5,000 for two lanes of detection. Of the two types tested, the infrared detection system seems to better alleviate the problem.
