From Wikipedia, the free encyclopedia
Inrix, Inc. is a nationwide provider of traffic information technologies, headquartered in Kirkland, Washington, USA. The company provides real-time and predictive traffic speed information for major freeways, highways, arterials and side streets in 92 U.S. metropolitan markets. Inrix is the exclusive beneficiary of development by Microsoft Research into the statistical inference of traffic patterns, predictive analysis and mobile-based visualizations of real time systems. It has built upon Microsoft's patented, proprietary technologies to enable the delivery of next generation traffic information services.
[edit] Predictive Traffic Technology
Inrix uses Bayesian statistical analysis models integrated with real-time traffic information, and a variety of other variables, to tell commuters not only what traffic is like right now, but also what traffic conditions will be like in the future and how to best avoid the trouble spots. Real-world variables used to predict traffic conditions include historic traffic incidents, road construction schedules, current and forecasted weather, school schedules, sporting and entertainment event schedules.
[edit] Smart Dust Network Technology
Inrix is the first company to successfully transform a large volume of GPS vehicle probe data into real-time traffic. Freeway and side street traffic speeds can be determined via the collection of real-time and historical sensor data from hundreds of public and private sources including real-time GPS data from more than 500,000 commercial fleet, delivery and taxi vehicles; toll tag data; as well as occupancy and speed measurements from Department of Transportation sensor networks.
