"Perhaps the digital sensors in smartphones can do a better job all by themselves.That's the idea behind Street Bump, an Android app piloted by the City of Boston. The app, which should be available to the public this summer, makes the smartphone's accelerometer do the job of sensing potholes. If you're driving and you hit a pothole while the app is loaded, Street Bump pairs up data about the size of the bump with a GPS coordinate - and sends that to a city database."
"Discouraged by the muddy data, the city decided to launch a global challenge in partnership with a group called InnoCentive. Liberty Mutual donated $25,000 in prize money for the group or groups that could use equations to distinguish between a pothole-y bump and all those other run-of-the-road vibrations.Three winners were announced, and the city is working to implement their algorithmic solutions now."
