The graphhopper routing library works very well (and fast) in general, but in certain cases we face problems with turns that does not regard traffic rules defined by the map. For example in Budapest, Hungary there is a place called “Blaha Lujza tér”. Left turns are forbidden here, however for some reason graphhopper makes it:
In contrast, the algoritm on openstreetmap.org handles this situation in the right way (see my next post).
We would be grateful if this problem could be solved somehow.
