I have to admit to getting a little confused looking at this initially, but it WOULD seem that the route IS legal. However, the slip road being used has obviously not been designed to handle traffic FROM the other side of the road. Initially I just thought the direction was wrong on the slip - and then I remembered to start driving on the wrong side of the road ;) I had a run around two customer sites yesterday. Both I know the route from here and don't need the sta nav, but I have never been across country between the two ( Worksop and Stockport ... ) so typed the post code in and followed the route. As I was going up the M1 and then across country, it became obvious that I had to take the instructions with even more of a pinch of salt than usual ... Bear right, and take exit often needed a little more information, such as keep to outside lane, or take inside lane. On at least one occasion I was having to change lanes late because of strange instructions - or no instructions at all, such as getting out of the inside lane because it did not go straight one! The google map is a good example of where a single way for a road does not provide enough information for the route planner to produce a SAFE route. This is another area where 'micromapping' may be very much more preferable to trying to add routing detail to a single way? Although in the case posted, the instructions "keep to outside lane and wait for clear traffic in the three lanes coming the other way" could probably be inferred, but I doubt that stopping the the fast lane would be appreciated by other drivers? -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk// Firebird - http://www.firebirdsql.org/index.php _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
