International Road Dynamics extends traffic monitoring contract in Oklahoma


Canadian company International Road Dynamics Inc. (IRD) has been awarded a new five-year US$4.23m contract by the Oklahoma Department of Transportation (ODOT) for traffic monitoring systems (TMS) maintenance and service.

Under the new agreement, IRD will provide installation, repair, service and calibration at 95 TMS locations across the state. ODOT traffic monitoring systems currently consist of 23 weigh-in-motion (WIM) and 72 automatic vehicle classification (AVC) stations.

All IRD’s systems that are 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. Weigh-in-motion locations also collect valuable axle weight data that can be used to estimate vehicle loading on the associated highways and infrastructure.

The new contract is a turnkey services agreement, with IRD responsible for all equipment, materials, labor, and technical expertise to successfully install, repair, maintain and operate all the state’s WIM and AVC systems. IRD’s transport monitoring systems allow the customer to receive a complete package of services and data from one experienced vendor.

Now a subsidiary of the diversified Industrial Internet of Things (IIoT) investment company Quarterhill, 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.

“We are pleased that Oklahoma has selected us for their installation and service needs, extending our more than 25-year relationship with the state,” noted Terry Bergan, IRD’s president and CEO. “This contract award is another successful example of how we are building our base of recurring service, maintenance, and data provision revenues, a key component of our value-enhancing strategies.”

As part of its long-term relationship with the agency, IRD recently supplied ODOT with multiple electronic screening systems (ESS), which provide the state with new, technologically advanced facilities that enable cost-effective screening of commercial vehicles for weight, credential or safety violations.

When IRD introduced its VectorSense Tire Sensor Suite, it offered the Oklahoma the potential to add screening for anomalous tires to its existing port-of-entry (PoE) commercial vehicle screening sites. ODOT agreed to a trial of IRD’s Tire Anomaly and Classification System (TACS) that has successfully identified truck tire problems. During the VectorSense trials, of the vehicles that were identified as having anomalous tires, 90% had serious enough defects to place the vehicle out of service.
