[Talk-us] Mapping traffic signals and stop signs using MapRoulette

I don't understand your roundabouts example. The give way before the
roundabout can be mapped on the road entering the roundabout, not ?
What's different from another road with a give way sign ? That the
roundabout is a one-way road ? Perhaps the rules for give way signs
before roundabouts are different between the US and Europe ?

The other examples add additional requirements and were not really
what I asked for.
I think those situations even do not exist in Belgium, which does not
mean we should not be able to map them, just that we do not need a
complex tagging system for our give ways.

If we follow the KISS principle, we can still map all the give ways
where we do no have those additional requirements without using
relations and keep relations for those cases where a give way only
applies to certain transportation modes or to certain directions. You
could compare to to not mapping turn restrictions if we can map it
with a oneway-tag.

I think you will not be able to convince me that relations are a good
thing for simple cases and I will not be able to convince you of the
opposite. But since there is no proposal for a relation, I cannot use
it. So unless someone writes a proposal, relations will not be used.
