Iowa first to use new Inrix Dangerous Slowdowns service


Following the release of its new Dangerous Slowdowns system, Inrix has announced that the Iowa Department of Transportation is now using its latest traffic services to monitor, measure and manage the state’s road network.

Inrix has been supplying real-time and historical traffic data to Iowa DOT for the last three years, in support of its traffic management and operations. For the new 2017 agreement, Iowa DOT will now make use of several recently added Inrix tools and features to support statewide traffic and incident management. As part of this agreement, Iowa DOT is now the first transportation agency worldwide to employ Inrix Dangerous Slowdowns, a newly-launched service that warns drivers and DOTs of sudden reductions in speed or stopped traffic on the roadway. It helps prevent back-of-queue collisions where rapidly forming congestion creates a situation that requires advanced driver awareness.

Iowa DOT will also use Inrix real-time traffic services that include:

• Performance Measures – an on-demand, cloud-based analytics suite that uses traffic data to help transportation planners understand what is happening on the roads, benchmark and improve performance, and maximize investment;

• Trips – provides insight into the trips people take, including where they begin and end their journeys, and the waypoints in between;

• Real-Time Traffic Flow – uses anonymous, real-time GPS data from millions of connected vehicles and devices to deliver the broadest and most accurate traffic information on all major roads.

“Drivers in Iowa are regularly confronted with traffic, and tackling congestion is a top priority for us. Secondary collisions at the queue is a problem plaguing roadways worldwide that also needs solving,” explained Scott Marler, director of traffic operations at IADOT.

“We are using Dangerous Slowdowns and other Inrix services to keep drivers safe and congestion at a minimum. Inrix real-time traffic services has helped us to actively manage traffic on our system and more accurately measure and report the impact of transportation investments. The quality of data and innovative features give us the tools necessary to keep congestion at a minimum, and keep drivers safe while on our roadways.”

Scott Sedlik, VP and general manager for global public sectors at Inrix, commented, “We are proud to supply road safety and traffic information that improves system management and incident response, as well as delivers better information to travelers in Iowa. The expansion of our existing agreement with the Iowa DOT further validates our world-class traffic services.”
