The geomagnetic detector registers vehicle passage. The detector is in the ground and may take the form of cobblestones. Data is sent to a nearby collector, such as a traffic sign or a public light. They are then sent to the central server for further processing and analysis.
This solution results in alerts about delays in a given section of the road, occupancy information and data for further analysis and prediction. People are able to choose a better transport route depending on the load.
IQRF provides extra low power communication which enables up to 4 years of battery life time. More over thanks to full bi-directional communication sensors could be debugged and upgraded over-the-air without extra service costs. IQRF also provides secure and reliable communication even in cases of water or snow layer on the ground.
