Sorry, my mistake. Certainly members should contains via, from and
to.<br>
<br>
While processing restrictions, gh look to restriction tag's value
prefix(no or only) and restrict or allow by from, via, to. There is
no difference between only_right_turn and only_left_turn if members
are equals.<div><div><br>

Restrictions must have members(from, to). In your case
restriction don't have them and it does not processed by
gh.

<div>OSM data has a turn restriction setup where
you can only turn right, however GH shows a left
turn.</div>
<div>OSM data uses a single node with
restriction:no_left_turn</div>
<div><br>
</div>
<div>Is this a sufficient relation? What is
required for GH to consider turn restrictions?</div>

<div>After reviewing the 0.4 list of
changes, it seems to me that turn
restrictions are enabled. I have
what i believe is the correct OSM
as well as config.properties file,
however I am not getting the
results I expect.</div>
<div><br>

<div>I am mobile right now, so I
can't post any detailed output,
but here is the config:</div>
<div><br>
</div>
<div>
<div>prepare.chWeighting=no</div>
<div>prepare.chShortcuts=no</div>
<div>osmreader.acceptWay=car</div>
<div>graph.flagEncoders=car</div>
<div><br>
</div>
<div># Enable turn restrictions
for car or motorcycle.</div>
<div># Currently you need to
additionally set
prepare.chWeighting=no before
using this (see below and #270)</div>
<div>graph.flagEncoders=car|turnCosts=true</div>
</div>
<div>graph.dataaccess=RAM_STORE<br>
</div>
<div><br>
</div>
<div>How does this config look?</div>
<div>My OSM has to from and via
relation elements. Any other tips
on how to correctly create the
OSM?</div>
