Important note- BRouter 1.4.8 has implemented turn restrictions, essential feature for car navigation.
The navigation RD5 data files need update if older than 24NOV2016.
In my understanding, car profiles do not need modification.
Reportedly tested by a german user on 5 turn restricted places in Berlin. See also the Germmen subforum.
http://brouter.de/brouter/revisions.html added turn restrictions (default for car, use considerTurnRestrictions=true for bike)
fixed elevation interpolation in start/end segments
fixed error message for very old data files
removed sanity checks when just reading nogos from waypoint-database
handling url encoded parameters
locus codes 13/14 for u-turns left/right
