#2835 closed defect (invalid)

Gosmore is routing incorrectly with very sharp angles

Have a look at the appended screenshot: (it is from a village "Handorf" in the North of Germany, near Hamburg and Lüneburg, see coordinates)

Coming from south (B404) and destination is in the west at "Bundesstraße" ... at point A gosmore is taking this sharp angle or even a U-turn. In reality, this is not possible an not allowed.

So routing has actually to over point B.

(Beware: both Bundestraße and B404 are national roads with one lane per direction and NO oneway-tagging in the OSM data! They are not crossing directly because of the bridge.)

How can we improve gosmore's routing?

(How does for example gpsmid or traveling salesman solve this routing?)

My opinion is that you should add a turn restriction to that junction:



from: the trunk road

to: the trunk_link

via: the connecting node

If you disagree, please send it to the routing list. Or email me and I will send it there.

Thanks for reminding me again.
