In France, around Paris, we have the same kind of areas.

The information appears to be relevant to the operator, but on the Paris 
region there are two operators (RATP and SNCF) using the same kind of 
information ("zones"); these areas and prices are defined by a local 
authority (STIF, Syndicat des Transports d'Île de France). Operators 
manage multiple kinds of transports: bus, subways, tramways and regional 

Inside stations where tarifications can differ, there are often 
separations of areas with automatic control points of transport tickets 
(or magnetic cards) with turnstiles. Example, between regional train and 

It is not always related to the deserved place: some places can be 
reached by subway (RATP, always in zone 1) and also by other means (bus, 
train...) in other zones. So in that case the information is relevant to 
a stop position only (not a full station).

We are looking for means to store the "zone" information the best way, 
since it has an important impact on the user navigation.
