Hyperloop vehicles spacing control challenges and possible solutions

Abstract

Amount of works and activities tending towards defining new transport mode on the basis of the hyperloop system concept is growing significantly. They assume use of individual vehicles, offering space for several dozen passengers, running with speeds near speed of sound in a closed space with significantly lowered air pressure, utilizing magnetic levitation. Simultaneously it is fairly from economic point of view assumed, that first implementations should link locations between which traffic demand is expected to be very high. Assumed short spacing between hyper-vehicles, which are frequently declared to be ad-hoc adjusted to transport demand, to the knowledge of the authors gained in railway transport, seems to be in conflict with high speed safety related spacing in view of the line infrastructure capacity operational rules defined in the UIC (International Union of Railways) documents. That is the challenge, that formed the basis for authors' investigations described in the paper. Several thesis regarding future new mode of transport based on hyperloop concept form an outcome of those investigations presented in conclusions.
