They are not part of the route? You could use something like the Karlsruhe Schema* for Addressing, to associate the bus stop with the road, whereby you could use the associatedStreet relation. The bus stops are part of the bus route relation too. One thing that should be noted is that at the moment relations are unordered. From API 0.6 (after this weekend, when there will be some downtime) relations will become ordered though the editors > > Bus Lines with a start and end bus stop that have a forward and > backward > direction but not using the same roads should be mapped as two > different > routes? You could do the same as the cyclemap does for cycle routes and use the forward and back roles, based on the direction of the way. > > Routing: > > Does anyone know about any experience of routing with public > transport? > > I've seen that in the NapTAN import there are 'naptan:' tags (QROTI > with > qroti:).

NapTAN is a UK dataset of bus stops that is being imported. * http://wiki.openstreetmap.org/wiki/Addressing Shaun _______________________________________________ Talk-transit mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-transit
