Arizona Selects INRIX for Real-Time Traffic Analysis and Optimized Road Planning

Analysis of traffic patterns allows state to more effectively manage the performance of road networks while minimizing costs

ADOT will utilize a suite of analytic tools and traffic services from INRIX and StreetLight Data to improve system planning, traffic management and operations:

  • INRIX Analytics is a suite of on-demand, cloud-based analysis tools that leverage INRIX traffic data across the U.S. They help transportation professionals understand what is happening on the roads, benchmark and improve roadway performance and maximize the investment of public funds. The platforms enable ADOT to analyze, visualize and understand road performance without the need for additional technology investments. The data and reporting is in partnership with the University of Maryland’s CATT Lab.
  • INRIX Real-Time Traffic Flow leverages anonymous, real-time GPS data from millions of connected vehicles and devices to deliver the broadest and most accurate traffic information on freeways, highways, interstates and major arterial roads. INRIX enables transportation agencies to monitor live traffic data including roadway name, time, current speed, typical speed and travel time.
  • StreetLight InSight®, StreetLight Data’s on-demand, cloud-based platform for transportation analytics, will allow ADOT to design, run, visualize and download analyses like origin-destination matrices for commercial trucks and personal travel modes. It combines the power of INRIX data, location-based services data from smart phones and ADOT’s own traffic counts with rich contextual data sets for a unique and powerful set of analytics.

Kirkland, WA – June 4, 2018 – INRIX, the world leader in transportation analytics and connected car services, today announced the Arizona Department of Transportation (ADOT) selected INRIX traffic services to support efforts to monitor, measure and manage the state’s highway network. As part of the agreement, StreetLight Data will enable ADOT to transform INRIX and other geospatial data into travel pattern analytics for statewide modeling. ADOT will now have greater insight into highway performance and problem areas, enabling better informed infrastructure planning and transportation investments.

“INRIX real-time traffic services help us better understand how the motorists use state highways so we can more effectively manage our system and prioritize how we’ll invest limited transportation funding,” said Dallas Hammit, ADOT state engineer and deputy director for transportation.

“ADOT is further enhancing road performance management across the entire state with on-demand traffic data and mobility services from INRIX,” said Scott Sedlik, vice president and general manager – global public sector at INRIX. “State officials can now quickly identify and understand specific problem regions throughout Arizona, efficiently resolve any issues and deliver valuable travel information to drivers.”
