¹ A journey can consist of one or more stages.  A new stage is defined when there is a change in the form of transport or when there is a change of vehicle requiring a separate ticket.

² Data published in 2015 erroneously included a value of 12.5 because of the exclusion of vans; this table contains the revised data.
