Crowdsensing smart city parking monitoring

Free parking search is one of the citizen's daily tasks which influences the most in the overall city performance. Pollution, traffic and productivity are deteriorated by cars looking for a place to park. In this paper, we propose the use of one of the features present in today's mobile phones, the magnetometer, to get a real-time map about free spaces in the street. We will demonstrate the viability of our work and preliminary results showing how the magnetometer “feels” the surrounding environment.
