Yes, but if you have a winding road, you will have to split it up into many small segments, with a different set of speed limit tags every time the road curves. You will also have ambiguous cases (if the road runs northeast to southwest, do you use the north/south pair of speed limit tags, or the east/west pair of tags)? -- John F.
