(EUROCABSottoprogetto dell’ERTMS (V.) che definisce e sviluppa...,). This First Level has the objective of increasing operational safety in any environmental condition of the road, transmitting on board secure information on the status of the signals on the ground, by means of the discontinuous and continuous channels which repeat on board the appearance of the signals imposed by the systemSistema (V.). of distancing present on the ground, and provide timely and geographical information on the route (start and end of controlled area, slowdowns, PLPassaggio a livello (V.)., crossroads, etc.). The same level allows you toTerminale operatore travel at the maximum speed allowed by the characteristics of the track and the train, implementing a safe speed control, in accordance with the infrastructures present, based on the distance between two consecutive signals.
