Abstract

Simulation test tool for validation of speed and distance on-board component of the European Train Control System Nathalie Cortial & Martin Krueger Alcatel Abstract The paper describes a simulation test tool developed by Alcatel for the validation of the positioning system component called Speed and Distance Measurement Unit (SDMU), in the framework of the European Train Control System project (ETCS). The positioning information delivered by the SDMU, critical to the supervision of the train and thus to the safety, should fulfil requirements in terms of dependability. Therefore, to be considered as safe, it should be validated with regard to specifications, hence the need of a systematic testing and validation method and simulation tool. The tool proposed comprises a complete simulation environment including functional modules dedicated to the simulation of train and motion, track, sensors and disturbances, and also a module to simulate relevant functions of the on-board
