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.
