Simple design of wireless sensor networks for traffic jams avoidance

Intelligent transportation systems (its) are usually approached by exhaustive measuring and complex signal processing including medium-high cost hardware deployment. in this paper,a novel design of a wireless sensor network system using magnetometers and microphones for the detection and avoidance of traffic jams is described and analyzed. the system,which can also be used for traffic monitoring and surveillance,is simple,energy efficient,and accurate which allows to be implemented with a reduced hardware cost. in order to reduce the maintenance tasks,mini solar panels would also be installed for powering up the motes in the near future. © 2015 víctor p. gil jiménez and m. julia fernández-getino garcía.
