In order to stimulate the switch of some car passengers to HSR, the speed of the transport in relation to the needs of the passengers, i.e. throughout the entire door-to-door leg of their journey, is crucial. It is therefore necessary to plan and organise the follow-up transport (first/last mile) using the public transport system (regional and urban follow-ups) and individual transport (station car parks, regional terminals in the hinterland of metropolises, charging stations for electric vehicles, etc.).
