The study, designed and conducted by a leading independent global marketing information firm, compared real-time traffic speed data from INRIX’s Smart Dust Network against NAVTEQ/Traffic.com in the areas of accuracy and market coverage. The ground truth testing research was conducted in three major metropolitan areas – San Francisco, San Diego and Miami.

Over 60 independently planned routes per metropolitan area were designed and tested to emulate “day in the life of” scenarios of average working consumers, ensuring a somewhat random distribution for each metro across major commutes and various times of the day. The drive tests were conducted over a period of two weeks and show that INRIX’s Smart Dust Network:

• enables a better customer experience than NAVTEQ/Traffic.com in the tested markets by reporting accurate traffic flow on many more of the routes tested on major roads
• provides highly accurate and statistically comparable accuracy rates of traffic speed information
• has significantly broader traffic flow information coverage in many more markets across the country than NAVTEQ/Traffic.com

Additionally, the study provides further support that INRIX’s unique approach to utilizing GPS vehicle probe data (blended with road sensor data where available) is, in general, at least as accurate as road-sensor collected data. Miami was the most accurate market tested in the study, and yet Miami has no physical road sensors, so traffic flow data in Miami is exclusively generated by INRIX through its GPS probe vehicle network.

This is the second significant comparative study conducted by a major independent research firm where results have confirmed INRIX’s position as the leader in the traffic information industry. A previous study, conducted in fall, 2006 by Frost & Sullivan in the markets of Washington D.C., Philadelphia and Providence, named INRIX as “the leading provider of real-time traffic information…based on coverage and accuracy”.

“We are laser focused on accuracy and coverage to deliver the best overall traffic and navigation experience for end users,” said Bryan Mistele, Inrix president and CEO. “These independent studies are significant validation of our unique and disruptive technology approach and our innovative delivery of traffic information.”

INRIX is the leading provider of accurate real-time, historical and predictive traffic information nationwide, providing industry partners and customers with the highest quality data and broadest coverage available for personal navigation, mapping, and other location-based service applications in the car, online and on mobile devices.

INRIX Traffic Services leverage sophisticated statistical analysis techniques, originally developed by Microsoft Research, to aggregate and enhance traffic-related information from hundreds of public and private sources, going well beyond the limitations of static road sensor networks, historical-based models and cellular data aggregators, to offer customers the most sophisticated understanding of the unique system-wide traffic patterns in each metropolitan area. Additionally, INRIX offers real-time incident data for 130 markets across the U.S. To experience the traffic technology revolution behind the next generation of navigation and location-based service applications, visit www.inrix.com.
