Here, I strongly disagree. The defination on the proposal page is clear: We do not want to have tags on the shared nodes. Only this way it is clear what is within the area, and what is without. We should not give up this possiblility. And your idea actually would give up this possiblilty. Next problem with your idea: You need to have shared nodes not only for incoming, but also for the outgoing oneways. And mostly there is no real traffic signal _after_ you have passed a crossroad. Nevertheless you have there a node. So later you won’t be able to know if on a specific node there is really a traffic signal or not. We don’t have any need to represent the individual traffic signals in the border. It would make the usage far to complicate. And you would not gain anything. If you want to mark individual traffic signals, use the existing tagging. But don’t invent a new one – don’t make it unnecessarily complicate! > 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. Here, I agree. I assumed that people would do so automatically, but I’ll also add it on the wiki page.
