The work proposes a quantitative model for the analysis of the resilience of railway lines with particular reference to the recovery activity through the setting up of a bus service. For each route between two stations, the interruption of rail traffic following a relevant event is considered; the aim is to evaluate which are the best stations where to set up the service and therefore the rail road interchange. The proposed model calculates for each station an Recovery Index (IR) on the basis of three indicators relating to the possibility to manage trains in the emergency conditions, the setting up of a bus service and the use of a bus-train interchange area. Each of the three indicator s, variable between 0 and 1, is calculated according to specific parameters and utility functions. Therefore, it is configured as a decision support system able to indicate the stations where the bus service is to be carried out. The model may also include other parameters in addition to those considered to take into account additional aspects such as economic and social impacts.
Il lavoro propone un modello quantitativo per l’analisi della resilienza delle linee ferroviarie con particolare riferimento all’assicurazione della continuità del servizio mediante autobus. Per ogni tratta compresa tra due stazioni, si considera l’interruzione della circolazione ferroviaria a seguito di un evento rilevante; l’obiettivo è la valutazione delle stazioni più adatte all’istituzione del servizio sostitutivo e quindi l’interscambio strada-ferrovia. Il modello proposto calcola per ogni stazione un Recovery Index in funzione di tre indicatori relativi alla possibilità di gestire i convogli ferroviari in condizioni di emergenza, di istituire un servizio sostitutivo con auto- bus e di usare un piazzale di interscambio treno-autobus. Ciascun indicatore, variabile tra 0 e 1, è calcolato in funzione di specifici parametri e funzioni di utilità. Esso si configura come uno strumento di supporto alle decisioni in merito alle stazioni dove attuare il servizio sostitutivo con autobus. Il modello può comprendere anche altri parametri, ad esempio per tenere conto di impatti economici e sociali.

Abstract
The work proposes a quantitative model for the analysis of the resilience of railway lines with particular reference to the recovery activity through the setting up of a bus service. For each route between two stations, the interruption of rail traffic following a relevant event is considered; the aim is to evaluate which are the best stations where to set up the service and therefore the rail road interchange. The proposed model calculates for each station an Recovery Index (IR) on the basis of three indicators relating to the possibility to manage trains in the emergency conditions, the setting up of a bus service and the use of a bus-train interchange area. Each of the three indicator s, variable between 0 and 1, is calculated according to specific parameters and utility functions. Therefore, it is configured as a decision support system able to indicate the stations where the bus service is to be carried out. The model may also include other parameters in addition to those considered to take into account additional aspects such as economic and social impacts.File | Dimensione | Formato | |
