Wrong guidance on particular type of Autobahn crossings

Reported by: nop Owned by: mvglasow (2)

Description

Navit creates wrong driving directions for Autobahn crosses where lanes cross under a bridge so you have to go straight if you want to change the Autobahn and vice versa.

Example: http://www.openstreetmap.org/?lat=49.4577&lon=11.24409&zoom=15

I was driving on A3 eastbound and my destination was to the south. To go there, I need to keep left as the left lanes cross under a bridge and turn south.

Navit highlighted the right lanes, but the driving instructions where "turn right...". Which is wrong as that leads over the bridge and you stay on A3 eastbound.

On the return trip, I encountered the same problem. To go from A9 northbound to A3 westbound you need to keep left. Navit instructed me to "turn right" which would make me stay on A9.

Windows 7, Map was OSM, Garmin map built from the same OSM data creates correct turn instructions at this location.

This issue has been fixed as part of Project HighFive? and the particular intersection is now a test case for routing.
