We study the demand and the willingness-to-pay for a new High-Speed (HSR) line on the Bari-Rome route, and its indirect effect on the connected Brindisi-Rome line, when competing with other existing transport modes. We carry out a discrete choice experiment over a significant number of respondents. We find that reductions in access and egress (A/E) time are more valued than in-vehicle travel time if HSR is available (faster services) while, when only traditional services are available, the opposite is true. This confirms that fragmented journeys, for faster connections, yield greater disutility and this would be the greater competitive advantage of HSR services. We also explore the heterogeneity among respondents, by studying the relationship between in-vehicle, and A/E travel time considering different population segments, i.e. different income levels, travel habits (frequent or occasional), and travel purposes, in order to profile potential users. We also study the patterns of the inter-modal substitutability. We find that increasing the travel distance by 120 km (to Brindisi) still guarantees large substitution between HSR and air transport mode.
