La crescente consapevolezza dei cambiamenti climatici e le sfide urbane contemporanee stanno portando a considerare la gestione delle infrastrutture con maggiore attenzione. Il Green Deal Europeo e gli Obiettivi di Sviluppo Sostenibile mirano a creare un'economia globale sostenibile. Poiché di tutta l’energia consumata nell’Unione Europea un terzo è a carico dei trasporti, ridurre le emissioni dei trasporti e i loro effetti negativi sull'ambiente e sulla salute pubblica è un impegno importante. Il trasporto ferroviario è sostenibile e ha tutto il potenziale per contribuire in modo significativo all'obiettivo di decarbonizzazione. Inoltre, sempre più persone prendono il treno, il che si declina in una crescente domanda di viaggi ferroviari e in un aumento della qualità e della quantità dei servizi offerti. Solo in Italia, più di cinque milioni di persone viaggiano in treno per studiare o lavorare ogni giorno, e il numero è in costante crescita. Un aumento degli investimenti per le infrastrutture ferroviarie si traduce in un maggior numero passeggeri. Questo è particolarmente evidente osservando il trasporto ferroviario regionale: nonostante una crescita complessiva del +5.1% tra il 2010 e il 2019, la situazione è estremamente frammentata a causa delle singole politiche regionali. È necessaria una nuova strategia di gestione per il trasporto regionale o locale, utilizzato principalmente dai pendolari, dato che la maggior parte di loro richiede diversi interventi, come l'elettrificazione e l'adattamento dei binari. Un altro settore ferroviario che potrebbe migliorare lo sviluppo della mobilità sostenibile è quello delle ferrovie dismesse, che solitamente offrono percorsi unici all'interno delle città e dei territori. Il patrimonio ferroviario può svolgere un ruolo significativo nello sviluppo sostenibile e nella rigenerazione del paesaggio a livello mondiale, in particolare considerando la conversione delle ferrovie abbandonate in greenways, reti di trasporto non motorizzate dedicate alla mobilità dolce (per ciclisti, pedoni, cavalli, etc.). Grazie alle nuove tecnologie, la trasformazione digitale offre numerose opportunità per una riconversione positiva del sistema dei trasporti ed è un elemento cruciale nell'affrontare la questione del rinnovamento e gestione delle ferrovie regionali, così come nella rivalutazione delle ferrovie dismesse. L'obiettivo principale è testare il potenziale di un sistema integrato che combini i Geographic Information Systems (GIS) e il Building Information Modelling (BIM) per la gestione di questo tipo di infrastrutture esistenti. Viene presentata una metodologia in tre fasi per sviluppare il sistema integrato e, per testare la metodologia, sono stati esaminati due casi studio nel Sud Italia. Dal punto di vista della gestione delle infrastrutture, la capacità del BIM e del GIS di gestire, analizzare e visualizzare i dati può offrire ulteriori informazioni per aumentare il valore degli asset, identificare e minimizzare i rischi e ottimizzare il processo decisionale nella gestione degli stessi, il tutto in accordo con la norma ISO 55000 (‘Asset management – Overview, principles and terminology’). Collegare i dati prodotti in ambiente BIM e GIS rende possibile la creazione di un modello digitale integrato del patrimonio costruito esistente, permettendo una gestione avanzata delle informazioni nell'ambiente costruito digitale.

Abstract
Infrastructure asset management (AM) is receiving more attention as a result of greater awareness of climate change and contemporary urban challenges. The European Green Deal and the Sustainable Development Goals aim to create a sustainable global economy. Reducing transport emissions and their detrimental effects on the environment and public health is a significant task, as transport accounts for one-third of all final energy consumed in the EU. Since rail is sustainable, it has the potential to contribute significantly to the decarbonization goal. Additionally, more people are taking trains, which meets a growing demand for rail travel and raises the quality and quantity of services provided. Only in Italy, more than five million people travel by train to study or work each day, and this number is steadily rising over time. An increase in funding for rail infrastructure translates into more passengers. This is particularly evident when looking at regional rail transport: despite an overall growth of +5.1% between 2010 and 2019, the situation is extremely fragmented due to the individual regional policies.
