Kirkland-based Inrix said today that it now provides traffic prediction services for more than 47,000 miles in 73 metropolitan areas.
This expansion became possible through the latest release of the company's new platform called the Inrix Traffic Fusion Engine. The company uses statistical techniques to predict traffic by aggregating events that affect traffic patterns and information derived from road sensors and GPS-enabled vehicles.
When Inrix first announced in May that it would be gathering information from fleet vehicles using GPS, it covered only 30 cities and 10,000 miles. Those markets included Miami, San Antonio and New York, each of which have had no data from road sensors.
The expansion means cities the company now covers include Cleveland; Hartford, Conn.; Knoxville, Tenn.; Tampa, Fla;, and Tucson, Ariz.
