IRD will provide installation, repair, service and calibration at 95 TMS locations, which currently consist of 23 weigh-in-motion (WIM) and 72 automatic vehicle classification (AVC) stations.

All systems installed in Oklahoma are solar powered and accessible via cellular modem. Traffic data collected at these stations include vehicle volume, speed, type, direction of travel, and time of travel. WIM locations also collect valuable axle weight data that can be used to estimate vehicle loading on the associated highways and infrastructure.

Under the turnkey services agreement, IRD is responsible for all equipment, materials, labour and technical expertise to successfully install, repair, maintain and operate all WIM and AVC systems. IRD solutions allow the customer to receive a complete package of services and data from one experienced vendor.  IRD provides a comprehensive program that includes the design, manufacturing, installation, collection of data, post-processing of data, report generation, and maintenance of data collection systems.
