A path between any two physical STOP PLACE SPACES within an interchange that represents a step of a possible transfer route for passengers within a STOP PLACE

NOTE: A STOP PATH LINK is a STOP PLACE COMPONENT in its own right and may have ACCESSIBILITY LIMITATIONS and CHECKPOINTS associated with it to indicate impediments that may prevent access or slow a user down. A sequence of one or more STOP PATH LINKS may make up a NAVIGATION PATH. Each end of a STOP PATH LINK connects to an entity that is a concrete subtype of an ABSTRACT STOP PLACE SPACE, that is, ACCESS SPACE or QUAY or BOARDING POSITION. Each end of a STOP PATH LINK may further have a specific ENTRANCE of the same concrete subtype of ABSTRACT STOP PLACE SPACE associated with that end, that is QUAY ENTRANCE, ACCESS SPACE ENTRANCE or BOARDING POSITION ENTRANCE. STOP PATH LINKs may be used only within an interchange. ACCESS PATH LINKS may be used for PATH LINKs outside the physical STOP PLACE.
