specialisation of a FLEXIBLE QUAY to identify what is the catchment zone for a hail and ride service (so that a stop finder can find the nearest available types of transport). It is a named zone visited by a particular mode of transport and may be designated by a start point and end point on the road

NOTE 1 to entry: It is part of the Site data set rather than the service data set, since it can be defined and exists independently of an actual service.
