[OSRM-talk] U-turn penalty?

[Xavier Prudent]

Dear all,

As a follow-up on my question, for anyone facing the issue:
my way out of this question of forbidding u-turns has been to get a local
version of the OSM map and to edit it using JOSM. I then applied detailed
constraints using the turnrestriction plugin.
Good luck!

Regards,

Xavier Prudent
