Performance Analysis of ITS-G5 for Smart Train Composition Coupling

Abstract

In this paper we present first measurement results the use of ITS-G5 technology for Smart Train Composition Coupling. Intelligent Transport System (ITS-G5) communication link has been already use for Train-to-Train (T2T) communications. The SCOTT(Secure COnnected Trustable Things) project focuses on Vehicle to Vehicle (V2V) communications as one of the main development lines in the Smart Train Coupling Composition (STCC) use case and additionally in Vehicle to Infrastructure bidirectional (V2I/I2V) communications as one of the main development lines in the Trustable Warning System (TWS) for critical Areas use case. The V2V communications development in the SCOTT project focuses on the decentralization of the communications in order to make low latency highly reliable communications between moving train composition. These use cases will end with the demonstration of a Virtual Coupling system relying on these decentralized V2V communications. This system increases the capacity of the railway lines all over the world by allowing train compositions to drive closer to each other in a safe manner. The investigated measurement categories are channel characteristics, system performance and environmental aspects.
