It is recognised in the literature that spatial accessibility is a measure of spatial equity and can be represented by the ease of travelling from an origin to a given destination via a given mode or set of transport modes. Although urban areas can benefit from improvements in accessibility when a new high-speed rail line is built, equity issues may arise. This manuscript describes a methodology for evaluating equity impacts due to an extension of the High Speed Rail network in Italy. A joint Revealed/Stated Preference survey has been carried out, collecting socioeconomic and travel data. Specifically, nine hypothetical scenarios have been submitted to Italian users aiming at understanding the motivations for not choosing the High Speed Rail as an alternative. The main outcome is that the access/egress travel costs connected with the High Speed Rail have a strong impact on spatial equity. The main policy implications of this study are that investors in high-speed rail should not only take into account the economic benefits brought by them, but also the spatial imbalance that these systems can bring.

È riconosciuto in letteratura che l'accessibilità spaziale è una misura di equità spaziale e può essere rappresentata dalla facilità di viaggiare da una origine ad una destinazione mediante un dato modo o insiemi di modi di trasporto. Anche se le aree urbane possono beneficiare di miglioramenti in materia di accessibilità, quando una nuova linea ferroviaria ad alta velocità viene costruita, potrebbero sorgere questioni di equità. Questo documento descrive una metodologia per valutare l'impatto sull’ equità connessa all’estensione della rete ferroviaria ad alta velocità in Italia. E’ stato effettuato un sondaggio sulle Preferenze Rivelate / Dichiarate, attraverso il quale sono stati collezionati dati socio-economici e di spostamento. In particolare, sono stati presentati agli utenti italiani nove scenari ipotetici volti a comprendere le motivazioni che li hanno indotti a non scegliere l'alternativa ferroviari ad alta velocità. Il risultato principale è risultato essere che i costi di accesso/egresso connessi al sistema ferroviario ad alta velocità hanno un forte impatto sull’equità spaziale. Le principali implicazioni politiche di questo studio sono che gli investitori in sistemi ferroviari ad alta velocità dovrebbero prendere in considerazione non solo i benefici economici portati da loro, ma anche lo squilibrio spaziale che questi sistemi possono portare.
