But don’t invent a new one – don’t make it unnecessarily complicate! I thought the shared nodes with the areas would easily represent what the signal_area is affecting, and when it is affecting it (before entering the intersection). Made a test to show you what I was thinking. https://www.openstreetmap.org/#map=18/36.32478/139.10396 > > > Also, I think It could also share nodes with the walkways and other > > pedestrian oriented ways, as the signal would be part of their routing as > > well.
