IRD Awarded $2.4 Million Virtual Weigh-In-Motion Projects for Illinois Tollway

• IRD will be installing three Virtual Weigh-In-Motion systems at two sites on Interstate Highways I-294 and I-88.
• The new systems will extend the network of Virtual Weigh Stations in Illinois that are equipped with IRD's tire safety screening solution.
• The Tire Anomaly and Classification System installations will be IRD's largest multi-lane tire safety sites to date.
• Virtual Weigh Stations and Tire Anomaly and Classification Systems help to improve road safety and are a key component of the Tollway's pavement preservation program.

SASKATOON, SK, March 31, 2023 /PRNewswire/ - International Road Dynamics Inc. (IRD), a Quarterhill Inc. (Quarterhill) company (TSX: QTRH) (OTCQX: QTRHF), announces that the company has been awarded two contracts for approximately $2.4 million for Virtual Weigh-In-Motion (VWIM) systems for the Illinois State Toll Highway Authority (Illinois Tollway). Under the contracts, three new VWIM systems will be installed at two sites for use by the Illinois State Police to monitor commercial vehicles for weight, size and tire violations. All financial information in this press release is reported in Canadian dollars unless otherwise indicated.

The project includes the installation of new VWIM sites on I-294 and I-88. Each site consists of Weigh-In-Motion sensors, iSINC® Weigh-In-Motion controllers, IP cameras, over-height detection sensors, and the Tire Anomaly and Classification System (TACS™). The TACS installations are the largest to date for IRD, with six lanes of TACS in one direction on I-294 northbound and three lanes in each direction on I-88 (eastbound/westbound). When completed, these sites will expand IRD's footprint of VWIM systems on the Illinois Tollway network from two to five.

The Weigh-In-Motion sensors will be used to screen for overweight vehicles, and the TACS systems will identify vehicles that are unsafe due to flat, missing, or mismatched tires. IRD's Virtual Weigh Station (VWS) web-based software will provide law enforcement officers with remote access to real-time data, including vehicle images, vehicle record data, and reporting. The TACS systems will be integrated with the VWS to display the locations of the tire anomalies on vehicle records. Under the contract, IRD will provide Illinois Tollway and ISP personnel with training on the operation of the systems.

"We are thrilled to be working with the Illinois Tollway to deliver this cutting-edge network of VWS systems," said IRD President and CEO Rish Malhotra. "Our technology has been proven in the previous VWIM deployments, and we are confident that the Illinois Tollway will see the same benefits in terms of pavement preservation, improved safety, reduced congestion, and lower costs. The scope of the tire safety screening component of the system is the largest we've booked to date and is an indication of the value the system provides and the confidence that experienced users have in the accuracy of TACS."

Given IRD's key partnership with Illinois Tollway and to maximize value to the State and enhance margins, IRD will be expanding its scope of work on this project wherein IRD's Construction Services unit will oversee the electrical and construction work, installing new conduits, power cables, junction boxes, and electric handholes, and overseeing site preparation.
