A methodology for assessing resilience of the HSR (high speed rail) network affected by disruptive event(s)

Abstract

This paper deals with modelling of resilience, i.e., vulnerability of the HSR (High Speed Rail) transport network affected by the system’s internal and external disruptive events both acting either individually or together/ The former events can generally be sudden unpredictable failures of the network’s components, i.e., particular facilities and equipment both on board the HS (High Speed) trolling stock and along the lines (power system, controlcommunications and signalling system, etc.). In addition, the specific events can be traffic incidents/accidents and industrial actions of the railway staff. The latter events can be natural disasters (for example earthquakes), bad weather (strong wind, heavy rain and snow falls, flooding, etc.) and terrorists; threats and attacks. In all above-mentioned cases, the given impacts are of the intensity to deteriorate scheduled/planned transport services causing their cancellations or long delays, thus imposing additional direct costs on the main actors/stakeholders involved such as userspassengers and rail transport service providers. In order to enable assessment of resilience, i.e., vulnerability of a given HSR network already being or is expected to be likely affected by given disruptive event(s), and estimate the overall costs of its impact, a convenient methodology consisting of the set of analytical models is developed with an explanation how it could be applied to the particular cases using the “what-if” scenario approach.
