Description

I came from south east (Albert-Schäffele-Straße) and had to turn left onto Planckstraße. I came from south east (Albert-Schäffele-Straße) and had to turn left onto Planckstraße. Navit told me to turn right (!) onto Gänseheidestraße. Technically I can follow the announcement, when looking on the map.

But when driving that announcement is at best misleading, I would even call it wrong (since I have to use the left-turn lane, not the right-turn lane at the crossing).

It was pointed out, there are two issues here:
-> When navit wants to navigate onto Gänsheisestraße, it should say straight not turn right, because that is the lane to use.
-> For turning left at Planckstr. navit should not mention Gänsheisestraße at all

I oppose the 'say straight' here. Current routing anouncements are 'further on' anouncements, not 'lane' anouncements. If there are four possible directions, I do not like the 'straight' announcement, if in reality it is the 'half right' or 'half left' direction. The lane anouncement would be fine, but should be a seperate option and not mixed up with the 'further on' direction. Just to clarify: There is no turning left into Planckstraße, it seems you mean Pischekstraße.

  • Severity set to normal

#795 is a slightly different issue, which has been fixed. This one here is a bit different and a bit more difficult.

We have, however, introduced a number of changes regarding announcements as part of Project HighFive?. Some of them deal with complex intersections – I'll have to test your cases and get back to you. Since this bug has been around for a while, OSM data may have changed and routing may behave differently because of that.
