This is a proposal for a set of tags and members making a Relation for networks.

A network groups together routes that share common characteristics, e.g. a common operator, a common classification scheme (e.g. E-road network: "E 1", ..., "E 999"), ...

Use cases

  • Person A sees a bus route with number 217 and wonders how many other bus routes exist in that city.
  • Renderer M wants to render all German motorways using white font on blue sign (official layout), and all E-roads with white font on green sign. This can be implemented by adding rules for relation 20614 (iD, JOSM, Potlatch2, history, analyze, manage, GPX, XML) and relation 20645 (iD, JOSM, Potlatch2, history, analyze, manage, GPX, XML).
  • Renderer M wants to render all cycle routes that belong to the "D-Netz". However, there are a lot of other national cycle routes as well.

Other benefits

  • The name of the route does only have to be typed in once and not in every member, which limits the possibility of mistakes.
  • Overlay websites/applications would be able to choose between networks more easily.
  • Possibility of use of roles
    • Proposing role: 'outer_limit' to be able to display the outer rim in a different fashion (different color or thicker line) on maps.
