Currently we are developing Turn-By-Turn functionality in our app for existing routes (no replanning) based on Graphhopper routing & instructions (you can see it in action in Dutch here). We are noticing missing instructions in some cases when turning, using the Foot/Bike flag encoders.
I haven’t found a similar question/situation on Github/Discuss yet, but if it exists, please correct me.
As these situations differ on other OSM routing engines (i.e. Mapzen/OSRM), which show correct instructions on those parts, we would like to contribute to improving Graphhopper to correctly handle these parts or to find the cause.
Illustration of the problem:
Examples (same issues apply for both foot/bike profiles):
Basically we want to know if this issue is known, what the cause is and what we can do to contribute to a solution.
