The lack of good turn-restriction information can be lethal. (Of course, this news story proves that people should keep looking at the road signs even when using sat-nav. It also proves that sometimes they do not.) Perhaps we need an explicit tagging for 'no turn restriction' at junctions. Data checking can then produce a warning for major road intersections where the turn-restriction info is missing. To keep the report manageable, it would have to be restricted to junctions where one of the roads is highway=primary or secondary. That's still a lot of checking to do. I have sometimes wondered whether harvesting GPS traces would help with this task. If every trace shows turning left at the junction, flag a warning for somebody to check whether a turn restriction needs to be added. But to do that we would need a bigger collection of traces, appropriately tagged to show which are from motor vehicles. -- Ed Avis <e...@waniasset.com> _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
