QUARTERHILL ANNOUNCES SYSTEM ACCEPTANCE OF TRANSITION OF TXDOT'S TXTAG USER ACCOUNTS TO HARRIS COUNTY TOLL ROAD AUTHORITY

The transition of approximately one million TxTag user accounts to the Harris County Toll Road Authority (HCTRA) back-office system has received system acceptance as of Friday, March 14, 2025. TxTag user accounts managed by the Texas Department of Transportation (TxDOT) have been serviced by HCTRA since going live in December, 2024.

Quarterhill Inc. has been a critical technology partner to HCTRA since 2002 and upgraded the authority's back office to a state-of-the-art system in 2017. Quarterhill designed the RiteHorizon solution as a multitenant back office to permit the processing of transactions by multiple agencies. A uniquely strong internal control system enables transaction tracking and revenue reporting by agency, facility, plaza and lane. Reporting, reconciling and settling transactions are separated and indicated for each authority. HCTRA now processes transactions for six different agencies with varying policies and degrees of involvement in customer service.

TxDOT internal reporting indicated that 60 per cent of its customers' transactions occurred on HCTRA-managed roads. By moving its user account management to HCTRA, TxDOT will improve efficiency by consolidating customer service and support. Consolidation will also create a unified customer service experience for drivers throughout the Austin and Houston areas. TxTag customers can keep using their current tags with the unified service.

The back-office system developed by Quarterhill was essential for extending HCTRA's high-quality service to TxTag customers. This partnership between HCTRA and TxDOT marks a significant advancement toward simplified and efficient transportation solutions.

"We are proud to support the seamless integration of TxTag users into HCTRA's advanced back-office system, powered by our RiteHorizon solution," said Chuck Myers, chief executive officer of Quarterhill. "This pivotal moment exemplifies how sophisticated technology can streamline operations, foster interagency collaboration and improve the experience for drivers. As these communities move forward under HCTRA's capable administration, supported by Quarterhill's robust systems, the benefits are clear: improved efficiency, cohesive customer support and a strong platform for future advancements in toll road management."
