Nericell

Nericell is a system which uses smartphones for rich monitoring of traffic data.[1] Nericell performs rich sensing by piggybacking on smartphones that users carry with them in normal course. Nericell uses the accelerometer, radio, GPS, microphone sensors in these phones to detect potholes, bumps, braking, and honking. Nericell addresses several challenges including virtually reorienting the accelerometer on a phone that is at an arbitrary orientation, and performing honk detection and localization in an energy efficient manner.[1]
