Proposal for tagging of highways

The official classification of regional roads is available as Decreto Legislativo Regional n.º 1/2013/M.

I have used the information from the Decreto and started to systematically tag roads as follows:

Kind of road	Number	Key	Value
Via rápida	VR 1, VR 2	highway	trunk
Via expresso	VE x	highway	primary
Estrada regional principal	ER 1xx	highway	secondary
Estrada regional complementar	ER 2xx	highway	tertiary
Smaller connecting roads, including old regional roads that have lost their ER classification		highway	unclassified

All segments of a regional road are tagged with its official number using ref=*, e.g. ref=ER 215.
All segments of one regional road become members of a Relation:route. The end points or other information about the route can be helpful and should be tagged as a note=* or description=*. (Example: Road is member of a relation with the properties type=route, route=road, ref=ER 215, description=Meia Serra.)
The vias rápidas and vias expresso are "on top" of estradas regionais. Therefore, for these parts of a estrada regional the ref=VR x (or ref=VE x) is set, and the ER number is not tagged on the way. However, the way should become a member of two relations, one relation for the VR (or VE) route and another relation for the ER route.
Old regional roads may be tagged with old_ref=* to store their old number. This might prevent other mappers from adding ref=* tags with outdated road numbers to these roads.

Additional info on old routes, as a source for old_ref=* tags, can be found in the out-dated Decreto Legislativo Regional n.° 15/2005/M. --Biff (talk) 07:29, 14 November 2013 (UTC)
