The new Vehicle Traffic Monitoring Platform from Libelium allows to create real time systems for monitoring vehicular and pedestrian traffic in cities by using the new Bluetooth – ZigBee double radio feature available in the Waspmote sensor board. The platform is capable of sensing the flow of Bluetooth devices in a given street, roadway or passageway differentiating hands-free car kits from pedestrian phones. Sensor data is then transferred by a multi-hop ZigBee radio, via an internet gateway, to a server. The traffic measurements can then be analysed to address congestion of either vehicle or pedestrian traffic.
