The INRIX Smart Dust Network is a breakthrough in traffic technology that dramatically advances the accuracy, coverage and quality of INRIX services. It collects more data about traffic conditions than any solution on the market today, acquiring real-time and historical data from hundreds of public and private sources – including anonymous, real-time GPS probe data from more than 800,000 commercial fleet, delivery and taxi vehicles; toll tag data from systems such as California’s FasTrak system; and road occupancy and speed measurements from Departments of Transportation around the country. INRIX is the first company in the industry to make use of all these valuable data sources.

The INRIX Smart Dust Network also factors in real-time incident data from across around the United States, as well as hundreds of market-specific criteria that affect traffic, such as construction and road closures, sports games and entertainment events, school schedules and weather forecasts.

While some traffic solutions rely entirely on road sensors – which are expensive and often error-prone – INRIX’s wide range of data sources enables it to provide high-quality information in cities and states where accurate traffic data was not previously available – such as Miami, Las Vegas, New York, Tampa, San Antonio and Providence, R.I. In fact, recent ground truth testing shows that INRIX technology was able to deliver an 8-15% accuracy advantage over traditional embedded road sensors.

The INRIX Smart Dust Network delivers better data than road sensors alone, and provides accurate real-time and predictive traffic speed information for major freeways, highways, arterials in every major metropolitan area in the U.S. and the U.K.
