physical (spatial) possibility for a passenger to access or leave the public transport system

Note 1 to entry This link may be used during a trip for: the walking movement of a passenger from a PLACE (origin of the trip) to a STOP POINT (origin of the PT TRIP); or the walking movement from a STOP POINT (destination of the PT TRIP) to a PLACE (destination of the trip).

Note 2 to entry: In IFOPT, a STOP PLACE, an ADDRESS, a POINT of INTEREST, a PARKING and a TOPOGRAPHICAL PLACE are all types of PLACE and so an ACCESS LINK may also explicitly connect them.
