Yeah, in a 2D problem space, with every vehicle already reporting position back to the network! The two dimensions being track offset (distance from start of line), and time. This isn’t even obstacle detection. This is a) obeying the speed limit, and b) not asking two known entities to occupy the same length of track at the same time. It does not, for example, detect a car stuck on the tracks at the next railroad crossing.
