Dave, I suspect that you and I will continue to disagree on the matter of highway=traffic_signal. I'm not sure I understand your argument above. Surely if you want to indicate where vehicles are to halt, that should be on the way? In my experience, the place to halt is different from the location of the signal controlling the intersection. If you are tagging beside the way, are you marking the location of the supporting pole? If the pole supports more than one traffic_signal[1], do you tag one or more? I don't support your method of tagging highway=traffic_signal, and I don't recommend it for newcomers to OSM. At a minimum, what you are doing is more complicated than the widely accepted practice of tagging the intersecting node that is controlled by the traffic signal. I do support your right to engage in this bit of micro-mapping. If you must continue this, please also include highway=traffic_signals on the intersecting node. Failing to do so will break the tools that expect the much-more-common intersecting node use. See also the area-micro-mapping example that includes traditional vector mapping, to support existing tools. To attempt to innovate at the expense of the accepted model seems ill-considered. And please consider working to advance the practice of micro mapping, by improving an existing proposal for junction, or intersection relations or something similar[2]. The best complex innovations in OSM are created deliberately, and by considering many contexts.
