Valhalla Route branches

71 views Asked by At

We are building a road traffic tracking system based on Valhalla, and we have a problem with road branches: enter image description here

here are quite a lot of such road branches, which is poorly estimated when calculating the distance. How to solve this problem?

Try changing server settings.
