Weigh-In-Motion (WIM) Sensor and Controller Operation and Performance Comparsion

The Kistler weigh in motion (WIM) sensors use a piezo-quartz technology to determine the weight of the vehicle as it passes over the sensors. They cost about $24K per lane to install. The Intercomp WIM sensors use a strain gauge type technology for determining the weight of the vehicle. This research would compare the accuracy and long term performance of both sensors. Then knowing the cost and the performance life of the sensors the study team can compare the data quality and the life cycle cost of the sensors and select the optimum technology.
