Formal technology-based training can be costly for all concerned. Efficient and effective alternatives to face-to-face training need to be found. One option is to use equipment simulators before undertaking formal training so that hands-on training can be conducted at a more advanced level and thereby increase efficiency. Case studies using Global Positioning System (GPS) simulations were condu...

High-mobility adaption and massive Multiple-input Multiple-output (MIMO) application are two primary evolving objectives for the next generation high speed train communication system. In this paper, we consider how to design a location-aware beam-forming for the massive MIMO system. We first analyze the tradeoff between beam directivity and beamwidth, based on which we present the sensitivity a...

Title : Impact of the automatic train supervision systems on safety Currently, railway tra c supervision systems are not considered as safety critical (basic safety constraints being ensured by other sub-systems). By taking a closer look, we can notice that these systems are able to prove their e ciency in safety management by o ering critical information to the supervisor confronted with a cri...

This paper is devoted to the development of a map matching algorithm for a train positioning system. Due to the nonsteerable truck design associated with rail vehicles, rail track curvatures are reasonably small. Consequently, track signatures, such as curves, are difficult to identify using low-cost sensors. The algorithm proposed in this work takes full advantage of the inherited “one-dimensi...
