So far, highway=traffic_signal is only defined for nodes and there are only few ways and fewer relations.
Also in favour of separation I would prefer to use junction=* with name=* and only highway=traffic_signal with name if it is only a single light (e.g. the case with a named junction and different separate names for the lights) This way we could add an additional junction=* to the nodes with named traffic_signal and once all lights are tagged separately only use junction=* for ways. Additionally we have a better hint for the renderer what to render and diversify between a named junction and single named traffic_signals. cu fly Am 17.09.2014 00:06, schrieb johnw: > Correct me if I'm wrong, but it sounds like the end goal is: > > - to have junction names in korea, regardless of if they are traffic > lights, and the symbol used there doesn't imply traffic lights, just a > junction. > > - In Japan, the old junction system evolved to be named traffic signals, > and the symbol used there a (horizontal) "signal" - so the end goal is > to have the name and the signal icon shown over the intersection with > it's name. > > > so the "complex solution" is to map the the junction, (with different > tags for Japan and Korea) with the area's way sharing nodes with the > traffic signals. > > - in Japan's case, the complex solution must only render a single > traffic icon, or it will ruin the purpose of using the intersection icon. > > > Note: > I'm not sure about Korea, but because there is no such thing as "street > addresses" in Japan - just lot numbers in (sometimes random) sequence > across the section, the sections are somewhat in a grid (regardless of > what street is adjacent to the property, or what street it gets accessed > from), all maps are used in a relative fashion (Start at Matsu Station, > go two lights down, turn left at the temple, and turn right at > intersection named "Honcho 3"), not in an absolute way (here's the 300 > block of Main street, and my goal is 322 Main St, so it will be right > about here). named intersections may be named in sequence, (Honcho 1, > Honcho 2, Honcho 3 in order) but this is not really reflected in the > location address.
