Title:
Standardized Testing Methodologies for Pavement Sensors
Abstract:
This project, funded by the Aurora Program, researched procedures for calibrating and testing RWIS pavement sensors. The project investigated existing procedures through a review of documented research and interviews with RWIS practitioners. Additionally, the study analyzed the perceived need for standardized testing methodologies for pavement sensors. The study revealed little practical agency-experience for testing and calibrating sensors. The Ministère de l'Equipment des Transports et du Logement (METL) of France is an example of an agency that is successfully performing their own calibration and testing of sensors. Their efforts have evolved to a level where climate chambers were developed for testing sensors. Within the United States, the Kansas DOT leads this effort. Due to their frustration with vendors, they took the initiative to test and calibrate sensors. The support for developing standard testing procedures is mixed among transportation professionals. While some view standards as a necessary development, others are happy to place the burden on vendors. As RWIS technologies continue to play a greater role in transportation maintenance activities, the accuracy of the data obtained will need to be repeatedly scrutinized. It is hoped that these finding will provide a foundation for further advancements in developing procedures for calibrating and testing procedures for RWIS pavement sensors.
