High Density - HD Using ERTMS: The Italian Solution for the Railway Traffic Management

The HD ERTMS solution for railway traffic management is presented. It allows to achieve “high density” railway traffic, increasing the number of trains on the existing railway lines. The proposed solution is based on the ERTMS technological standard and can be integrated with existing signaling systems minimizing field intervention: HD ERTMS trains do not interfere with trains equipped by other signaling and train separation systems. The railway traffic simulation software RFI NET has been upgraded to verify HD ERTMS potentiality and to optimize rail traffic on lines, nodes and stations. Finally, results of the first HD ERTMS application to the Italian railway node of Florence are presented.
