Assigning Stops

The Stop Assignment model relates the scheduled use of stops by services in the timetable with the actual physical STOP PLACES and QUAYs that exist.

A SCHEDULED STOP POINT in the timetable may be allocated to entire STOP PLACE or to a QUAY within it.

Note: In many legacy systems, stop assignment is implicit – the same identifier is used both for the STOP PLACE and for the SCHEDULED STOP POINT and they are considered to be the same. A platform (QUAY) identifier is treated merely as an annotation and no attempt is made to model the physical stop. The Transmodel representation, though more elaborate, is more expressive in that it can describe platform changes, the temporary displacement of stop points, etc, the different boarding points for replacement services, the navigation between platforms, etc. It also makes it easier to integrate different code systems from different modes at multimodal interchanges.
