The point of Clearflow is to provide accurate route information that gives you the best chance to avoid traffic on highways and on the side streets. By logging data from 16,500 trips over 125,000 miles, Microsoft engineers came up with algorithms to predict traffic flow on highways and adjacent streets, the latter of which can be even more crowded than the main arteries.
Using the data collected in Seattle, along with the results from highway sensors, the system works for 72 cities, and can "predict congestion based on time of day, weather and other variables like sporting events." Clearflow went live Thursday, April 10, with the choice to "Choose route based on traffic".
