Kirkland, WA. – INRIX announced today that that the I-95 Corridor Coalition has completed the most comprehensive validation of vehicle probe data ever in the U.S., finding that the quality of INRIX traffic information “provides an accurate overall picture of traffic conditions for limited access roadways within the corridor.”

The four month I-95 Corridor Coalition study analyzed traffic on 111 miles of highways across Delaware, Maryland, New Jersey and Virginia. Using innovative Bluetooth reader technology, the study compared 19,000 observations of ground-truth vehicle speeds for over 1,500 hours on 54 road segments against real-time speed information for those road segments that INRIX provides as part of its contract to the Coalition.

The University of Maryland, contracted by the I-95 Corridor Coalition to conduct the study, found that the INRIX travel time and speed data across the system and by individual states generally satisfied the accuracy specifications of the I-95 Coalition Vehicle Probe Project contract. Further review established that in over 85% of the ground-truth comparisons, INRIX traffic data was within 5 miles per hour of the ground truth speeds. The study concluded “this result confirms that the INRIX GPS data provides an accurate overall picture of traffic conditions for limited access roadways within the Corridor.”

“This I-95 Corridor Coalition study is another clear validation of INRIX’s unique approach to building the broadest and most accurate traffic data network on the market,” commented Rick Schuman, vice president of public sector at INRIX. “The Coalition should be applauded for conducting one of the most comprehensive evaluations of vehicle probe data ever completed. We intend to continue our extensive collaboration with the I-95 Coalition and its member agencies as they integrate data from the Vehicle Probe Project to maximize the project’s value.”

In a further industry effort to demystify the quality analysis of traffic information, INRIX published today Benchmarking Traffic Data Quality: Best Practices for Analyzing the Quality of Traffic Information. The 60-page guide is designed for automobile OEMs, transportation agencies, wireless carriers and developers of location-based services to showcase best practices, metrics and INRIX thought leadership on the important topic of traffic data quality.

This technical primer on traffic data quality provides a benchmark from which to evaluate the many components that make up the quality of traffic information. The report describes the processes and methods INRIX uses to validate, measure and verify the quality of incoming traffic reporting data. In addition, it outlines best practices for the planning and execution of ground truth testing of traffic flow data, including the results of tests conducted by INRIX and its partner, Clear Channel Total Traffic Network.

Benchmarking Traffic Data Quality includes the results and an executive summary of the I-95 Corridor Coalition quality validation and is immediately available at www.inrix.com.

As part of INRIX's public-private partnership with the I-95 Corridor Coalition, we recently provided real-time traffic monitoring tools to the Maryland State Highway Administration for transportation planning leading up to and through the presidential inauguration.

During the Martin Luther King Jr. Birthday/Inauguration weekend, the Maryland State Highway Administration was able to monitor speeds in real time on the freeway and major arterial network in the greater Baltimore/Washington corridor for the entire weekend.
