Modello quantitativo per lo studio dellaccessibilità ferroviaria con veicolo bimodale in condizioni di emergenza.

This paper proposes a quantitative method for evaluating the accessibility o f railway routes in the open air under emergency conditions using the bimodal roadJrail vehicle supplied to the Fire Brigade. The model is set up as a Decision Support Tool - DST useful for assessing current accessibility o f each link that makes up a railway line and identifying any road/rail access points that could be improved and/or implemented. The model was applied to a section o f the old MilanTurin line in order to verify the validity and reliability o f the proposed tool. The results o f the tool can be used in a pre-event and a post-event phase: in the first case, the objective is to plan, programme and eventually achieve the accessibility im provements; in the second, the joint management o f emergencies can be supported which requires the arrival o f rescue teams in the shortest possible time.
