Improving the mobility of large urban areas is an exciting challenge that can also address sustainabledevelopment issues. With that target in mind, the Great Lyon has decided to experiment a smart network ofwireless magnetometers to optimize their road infrastructure use. Sensors will provide volume, speed dataand travel times based on vehicle magnetic signature recognition. Those data will feed algorithms aiming attraffic regulation, and one hour traffic prediction giving the opportunity to reduce and delay the congestion.
