This paper investigates the handover performance on high speed train (HST) via different speed under three scenarios, which are viaduct environment, cutting environment and urban area. To provide stable wireless service, we adopt Long Term Evolution (LTE) for high speed railway (HST) system. Moreover, we consider the effect of speed on handover procedure. Interchannel interference (ICI) caused ...

Abstract With the rapid development of economy and technology, people’s quality life has been continuously improved, which also makes people put forward higher requirements for transportation. As far as railway transportation is concerned, running speed route trains in past gradually failed to meet travel needs. Automatic train operation system (ATO), under protection automatic system, realizes...

In the event of a collision between a traveling, high speed train and a vehicle, the scale of human fatality and property damage can increase substantially if the train derails from its track after impact. Hence, it is important to identify the conditions and factors that may potentially lead to derailment in the event of a train-vehicle collision incident at a highway rail grade crossing. This...

-For the rapid development high-speed railway system, improvement approach of the velocity measurement accuracy has been studied based on multiple speed sensors on high-speed train. In this method, the velocity measurement data from multi-channel speed sensors were dealt through data fusion of arithmetic mean filter, weighted arithmetic mean filter, Federated Kalman filter and adaptive Federate...
