TrafficSense: Rich Road and Traffic Monitoring Using Mobile Smartphones
To monitor road and traffic conditions in such a setting, we present TrafficSense, a system that piggybacks on smartphones that users carry around with them. Each participating smartphone performs rich sensing using its communication radios, GPS, accelerometer, and microphone, scans for and exchanges information from other participating phones in its neighbourhood, and reports processed information back to a central server for aggregation and reporting. We discuss key technical challenges, including energy optimization and the need for hands-free operation, present the design of TrafficSense, including how information from multiple sensors is combined to make inferences, and evaluate it in various road and traffic settings in Bangalore.
