Yes, but only in the case of tagging the traffic signals at the intersection node. If the traffic_signals tag is placed on a way node, then there is ambiguity. A human observer might guess that it applies to traffic directed to the nearest intersection - and one might even implement that as an algorithm... But it is ambiguous at best. > I don't think with the present state of data consumers, that there is > necessarily a "right way" to do this.

And expressing themselves early will save everyone some of the chaotic period that precedes the settling in of perennial tags. Implementation rules but discussing it a little beforehand is valuable. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
