IRD awarded new WIM systems and services contract by Caltrans


Canadian company International Road Dynamics Inc. (IRD), now a wholly owned subsidiary of Quarterhill Inc, has been awarded a contract valued at US$5m by the California Department of Transportation (Caltrans) to provide equipment and software maintenance and on-call service for its statewide network of weigh-in-motion (WIM) systems.

IRD’s new service agreement is effective immediately and runs through to the end of December 2020. The contract provides for the maintenance of both Caltrans’s commercial vehicle enforcement systems and traffic data collection systems.

The state’s commercial vehicle enforcement systems are used to screen trucks based on weights, dimensions, safety and credentials, and Caltrans’s traffic data collection systems provide 24-hour information at key locations on California highways. The data collected from each location includes axle and gross vehicle weights, axle spacing, vehicle classification, and speed information. The data is essential for Caltrans’s pavement, highway monitoring and capacity studies, accident rate calculations, and the analysis of truck transport practices.

IRD has a longstanding relationship with Caltrans, having provided equipment, maintenance, software maintenance, and on-call services for the agency’s statewide network of WIM systems at approximately 200 locations. The company has deployed over 500 lanes of traffic data collection systems using WIM technology across California, and most recently provided a high-speed WIM and verification system for a new Commercial Vehicle Enforcement Facility (CVEF) in Solano County.

IRD notes that its expertise and experience in the WIM Data Collection field allows Caltrans to receive a complete package of products and services from just one vendor.

IRD’s equipment in the state consists of both Bending Plate and Piezoelectric sensor WIM systems. These WIM systems provide the state with comprehensive traffic data used for planning, with key systems used for truck enforcement bypass as part of Caltrans’s involvement in the Heavy Vehicle License Plate (HELP) Inc. program.

As part of this freight pre-screening program, the enforcement bypass sites are integrated with the PrePass Pre-clearance program, run for HELP Inc. by ACS (Affiliated Computer Services, formerly Lockheed Martin IMS).

“We have been a long-term systems and service supplier to Caltrans, and this new contract underlines our ongoing commitment and positive relationship with the state,” commented Terry Bergan, IRD’s president and CEO.

“We continue to renew our key multi-year contracts and sign significant new agreements within our service and maintenance markets around the world, increasing the recurring revenue aspects of our business.”
