Collaborative environment for road traffic monitoring

Abstract

We present a collaborative, distributed solution for gathering high quality quasi-real-time data regarding the conditions on public roads in an urban community by using a mobile sensor network implemented on smart-phones. Our solution for collecting data is based on a series of mobile nodes running a custom application and a Java server responsible for aggregating and processing all the data and building a state of the roads at a specific moment. Users are presented with a web interface for querying the data in a geo-enabled manner. A specialized algorithm is developed an presented for collecting data in absence of GIS information.
