Normal Conditions for 7:00am
Monday August 13th, 2007 in Seattle

Leveraging technology originally invented at Microsoft Research, INRIX employs Bayesian statistics to make predictions about future traffic conditions – whether they are 15 minutes, 15 days or 15 months into the future -- determining the combination of factors that will influence future traffic patterns and uniquely developing an in-depth understanding of what traffic is like in each metropolitan area.

The technology combines input of commonly known traffic-impacting factors such as the current traffic conditions, day of the week, season, holidays and related days, current and forecast weather, accidents and road construction, as well as other events such as school schedules, sports games and concerts, and even uniquely local variables such as the legislative calendar in Washington, D.C, or the convention schedule in Las Vegas. This allows INRIX to make predictions conditioned on dynamic knowledge of current and future conditions.

INRIX® Bayesian Prediction of Conditions
for Monday August 13th, 2007 in Seattle
during I-5 Northbound construction project.

Using an evolution of this technology, INRIX scientists have been successful in accurately predicting the impact of previously unseen construction, road closure and incident events on the traffic conditions in a market correctly capturing detour relationships between alternate routes, and public behavior in response to knowledge of incidents, events and construction. Such predictions result in very different information to time-of-day, day-of-week typical conditions data that can be derived from historical averages of traffic patterns.
