Proposal:Extended traffic signs tagging/Destination signs

Destination signs

Destination signs specifically are one of the most complex and complete sets of information you can find in a road. It marks the destination, the direction, the way to, the distance...

Nowadays aproximation

Destination sign is tagged as a relation. This is to have unambigous guidance because you mark the roles node by node. But you have to do a relation-per-exit.The keys are destination, distance, time, colour:back, colour:text and colour:arrow.

[Destination as a way] is used to mark the info by lanes or in ways where indicated destinations are identical from all directions.

Alternative aproximation

Tagged as a node. With the same scheme of the other traffic signs, including second or third panel. It includes all the elements you can see in the panel , and also all the destinations with the order and the position in the panels as a subtags.

Tag	Common values	Comment	Example	Image
destination:ref=*	*	reference of the destination	destination:ref=5
destination:int_ref=*	*	international reference of the destination	destination:int_ref=E18
destination:upper	*	upper option of destination	destination:upper=Niederbipp
destination=*	*	middle or unique option of destination	destination=Colfosco
destination:lower	*	lower option of destination	destination:lower=Limon
destination:symbol:upper	*	symbol of the upper destination option	destination:symbol:upper=pedestrian
destination:symbol=*	*	symbol of the middle or unique destination option	destination:symbol=cafe
destination:symbol:lower	*	symbol of the lower destination option	destination:symbol:lower=industrial
destination:distance:upper	*	distance of the upper destination option	destination:distance:upper=145
destination:distance=*	*	distance of the middle or unique destination option	destination:distance=6
destination:distance:lower	*	distance of the lower destination option	destination:distance:lower=679
lanes=*	*	number of the lanes, it is used also for the number of arrows you see at the traffic sign panel	lanes=1
ref=*	*	reference/number of the exit	ref=211A
turn:destination=*	*	direction of the arrow in the panel or the panel itselfs	turn:destination=right
distance=*	*	distance to the exit	distance=1200m
colour:arrow=*	colour=* values	colour of the arrow	colour:arrow=white
colour:back=*	colour=* values	colour of the panel	colour:back=yellow
colour:ref=*	colour=* values	colour of the reference	colour:ref=blue
colour:int_ref=*	colour=* values	colour of the international route	colour:int_ref=green
colour:text=*	colour=* values	colour of the text of the panel	colour:text=white

These are the main tags for the description of the destination signs. Some other keys and subkeys are used to distinguish the differents destination signs if there's more than one.

traffic_sign:x_panel:forward : national ID code for the traffic sign.

Tag=value	Comment	Example	Image
lower_panel	panel below the main or unique panel	colour:arrow:lower_panel=white colour:back:lower_panel=green colour:text:lower_panel=white turn:destination:lower_panel=left destination:lower_panel=Basel
end_panel	panel below the lower panel or at the end side of the panel when there are two exits near each other.	colour:arrow:end_panel=black colour:back:end_panel=white colour:ref:end_panel=red colour:text:end_panel=black destination:end_panel=Bilbao destination:ref:end_panel=N-634 lanes:end_panel=1 ref:end_panel=18A turn:destination:end_panel=sharp_right
main_panel	main panel that shows main destinations at the motorway or at a road	colour:arrow:main_panel=white colour:back:main_panel=blue colour:ref:main_panel=yellow colour:text:main_panel=white destination:main_panel=* destination:main_panel=Woerden destination:ref:main_panel=N212 lanes:main_panel=2 turn:destination:main_panel=through

Crossings and roundabouts

With this advanced scheme it is possible to map all kinds of crossings, normal roundabouts , tram roundabouts and turbo roundabouts. Also there is a set of tags for each available direction.
