QUARTERHILL AND IDOT PARTNER TO ADVANCE TRAFFIC DATA AND INTELLIGENT TRANSPORTATION INFRASTRUCTURE ACROSS ILLINOIS

Quarterhill Inc. has entered into a long-term partnership with the Illinois Department of Transportation (IDOT) to install and maintain traffic data collection sites across District 1, covering northeastern Illinois and including the Chicago metro area.

Valued at approximately $2.5-million over an initial three-year term with an optional annual extension for up to 10 years, Quarterhill's market-leading technology will support IDOT's ability to maintain and expand its traffic monitoring infrastructure across state-maintained roadways while helping strengthen the data foundation behind safer, more efficient transportation planning and roadway operations across the region.

Under the agreement, Quarterhill will work closely with IDOT to install new continuous count sites (CCSs) and maintain existing locations, helping ensure traffic data remains accurate, consistent, and available for IDOT's day-to-day operations and long-term planning. CCS sites collect year-round data on traffic volume and vehicle types across Illinois roadways, which is used to design roads, manage pavement and bridges, analyze freight and passenger movement, improve safety, and plan future infrastructure investments. Quarterhill's technology helps ensure these data can be reliably used across planning, engineering and policy decisions, transforming roadway data into actionable intelligence that helps shape the future of mobility and infrastructure investment across Illinois.

"The future of roadway planning will be driven by reliable, data-informed transportation systems," said Chuck Myers, chief executive officer of Quarterhill. "Our partnership with IDOT ensures that Illinois has effective traffic data to better support decisions around safety, infrastructure and overall system performance, supporting a more connected and responsive transportation network for drivers and communities across the state. Furthermore, this contract underscores the momentum Quarterhill is building as it capitalizes on a sustained, multiyear global transportation modernization cycle."

By maintaining CCS infrastructure and supporting consistent data output, IDOT strengthens its ability to integrate traffic information into its reporting and decision-making tools. These capabilities help transportation agencies better understand traffic patterns, manage infrastructure more pro-actively and plan investments with greater confidence as transportation demands continue to evolve across the region.

This award builds on Quarterhill's growing presence in Illinois, following its previously announced work with the Illinois State Toll Highway Authority (Illinois Tollway) and reflects the company's growing portfolio of long-term relationships with transportation agencies across North America. In 2026 alone, the company has announced contracts with agencies in Indiana, California, New Jersey and Massachusetts.
