I thought one would tag nodes on the highway where it's enforced, not the location of the devices themselves? I don't think it's easy to unambiguously make the connection of a speed camera on top of a bridge (which would then be tagged as a node of the bridge I guess?) with the highway below where the speed is enforced? > * On a crossroads/traffic signals (red light camera) where two ways > cross, in which case forwards and backwards are meaningless (two or > more ways share the node) But so would N/E/S/W be if two roads cross at sharp angles and both roads would be in the N sector for example.
