This would not be the bells and whistles method, but the bread and water method. The basics that would have the routing working and the map displaying things.


Both wiki pages are up to date and pretty prefect. "Up to date" means that more than 90% of all public transport objects are mapped that way.

From a semantic way, it would only be necessary to drop a few words for
- tram stops without a platform
- subway stations: if the underground structure is not known then you should map at least "railway=station" + "name=<Name>" and all entrances
And a decent mapping scheme would be complete.

I have written routers for passengers, routers for the operators, a route display tool
and a JOSM plugin for editing public transport. Bottom line: Nobody, really nobody needs relations of type stop_area, stop_area_group, route_master, network, and stop_position information.

This is also the thing I do not like about the proposal: it is again cluttered with also that complexity, mixing the important with the unimportant and the commonplace with the obscure.

The upside is: public transport is in a much better state than all the discussion contributions suggest. Public transport operators from five continents are now voluntarily using OpenStreetMap data for a wide range of purposes, because it is good enough to do so.

For discussing details I suggest the relevant mailing list
It is purely about public transport and has some hundreds of subscribers. On this mailing list "tagging" here, between golf courses and detached houses relatively few people will find this discussion in the long run.

Best regards,
