Abstract:
This project summary report summarizes the research performed in Texas Department of Transportation (TxDOT) Project 0-4664. This project sought to: (1) locate and conceptually design a traffic monitoring equipment evaluation facility, (2) identify funding sources, (3) evaluate the accuracy and performance of Kistler LINEAS quartz piezoelectric sensors, and (4) gather information on the type and minimum pavement depths for weigh-in-motion sensor installation. The research team investigated possible funding sources for the design and construction of the traffic monitoring equipment evaluation facility. To locate the facility, the research team developed and weighted 21 criteria by which candidate sites would be judged. Researchers developed a conceptual design for the traffic monitoring equipment evaluation facility. The selection process chose a site in Bell County. For evaluating quartz piezoelectric sensors, the research team surveyed state departments of transportation on their experiences with Kistler quartz sensors, which was generally positive. Researchers also evaluated the sensors- performance at three test sites, which indicated good condition performance of the equipment. For the type and minimum pavement depths for weigh-in-motion sensor installation, researchers found that bending plate systems should be installed only in concrete pavements with depths not less than 12 inches.
