In this work, we present SIMPLE, an integrated platform that offers simultaneous and coordinated management of both railway level crossing and surrounding road traffic. The platform features a new radar sensor that provides superior safety in detecting lost loads or vehicles trapped in the level crossing barriers as well as a road monitoring system, based on novel paradigms for the IoT and including an ETSI M2M compliant Smart Camera Network (SCN) and Gateway. On the base of the data collected by the sensor deployed on the field, a suitable computational unit performs simulations and provides forecast both on railway circulation (and thus level crossing closing times) and on road circulation. Results collected during a field test are reported and discussed.
