Documentation on how to assure data quality of public transport routes in OSM

[pantierra]

In order to generate proper GTFS files good data quality in OSM is recommended, if not required.A little writeup/manual would help users how to assure data quality.

I think the wiki here would be the best place to live for this information. Maybe once it's getting to be more complete we could integrate it into learnOSM.org

Just a rough brainstorm list of the contents I suggest to include:

• Use JOSM, the PT_Assistant plugin, and the OSM standard public_transport:version=2
• Clean up all verification errors related to PT.
• Make a list of recommended tags to be on the relations and which are used in osm2gtfs

Another thing to include: How to download PT data in JOSM comfortably using this query (or similar):

[out:xml][timeout:125];
(
relation["public_transport:version"="2"]["route"="bus"];
relation["public_transport:version"="2"]["public_transport"="stop_area"];
node["public_transport"="station"];
way["public_transport"="station"];
);
(._;>;);
out meta;

Great idea! Please be invited to start with this in the wiki!

Thanks also for this JOSM query example. Didn't know that was possible.
