“…The catchment area of FFPT may include a particular transport network. In practice, this may mean any of the following: the entire area where public transport services are provided, a specified area (e.g., town centre), specified routes, specific public transport mode (e.g., only ferries), particular hours (e.g., off-peak hours), particular days (e.g., every first day of the month, weekends or Car Free Days) or particular group of users (e.g., students, children, elderly or visitors and tourists) [20,21]. For more on the various forms of full and partial FFPT, see for example [20][21][22].…”
