This section describes the standardization desired for this project. Listed below is a minimal set of tags. Additional tags can be added, as appropriate, but mappers should feel comfortable moving on if these have been included as a first pass.
this is assumed on road segments tagged highway=motorway
Relations
When should segments be added to an Autobahn route relation?
Not until they have been designated as an Autobahn with Key:ref. The current "Bundesautobahn" system only applies since 1975-01-01.
East German motorways between 1974 and 1990-10-02 with Key:official_ref. All relations since 1990-10-03 follow the same criteria as West German ones.
When should relations be created?
For each segment, for each time period. For example, A 1 (Schleswig-Holstein), A 20 (Mecklenburg-Vorpommern).
You can then group each segment into a Bundesautobahn 1 relation or a Bundesautobahn 20. Short motorways which cross state lines only need this relation
All route relations should be grouped into a chronology relation
put the number of the Autobahn, with the "A" prefix; NOTE: previous internal numbering schemes can be tagged as official_ref=* with a seperate route relation
Use this table to document route relations on the former GDR. Progress of road mapping should be documented on the section above. For the network key use network=DD:A
Use this table to document route relations in West Germany prior to the Bundesautobahn system. Progress of road mapping should be documented on the section above. For the network key use network=DE:A
Only motorways shown, that are present today. Route description only covers maximum extent based on current motorway network. Other routes and numbers that were cancelled are not shown. Some routes might not have opened before 1975.
