I personally see no problem with adding 'nodes' where the stop lines are so
that another mapper in the future can add, say,
'highway:traffic_signals=stop_line' or something similar once we nail down how
to 'link' all traffic lights in an intersection and come up with a proper
tagging scheme
Well, the problem here is, that even though OSMAnd says 'make a U-Turn',
vshcherb says the following about it:
Technically this is not U-Turn, cause it goes to another OSM way.
U-Turn when you get back to the same road, because most of the roads are
drawn as 2 ways, that's why U-Turn is just

In reality there is only one set of stop lights there, correct? In other
words, if one were headed south on McKnight Road turning east on Seibert,
one would not have to stop (assuming red lights) three different times.
1) A routing engine should have some heuristics to interpret the three (in
2) There should be some cost in a routing engine for making a u-turn so
as to discourage such routes even if there was an extra set of signals.
Making a u-turn does take time (one can not go from the posted speed
limit in one direction to the posted speed limit in the other direction

This issue reminds me of something I saw a lot of recently on OSMin Fort
Collins, Colorado. I get the impression that the mapper whodid this editing
did it as a way to avoid the problem(s) mentionedregarding routing. When I
first saw this peculiar way of mappingtraffic signals, I didn't
