Hello,<br><br>Not sure if this was ever mentioned/explored before.<br><br>I looked at the document at <a href="http://svn.parabola.me.uk/display/trunk/doc/nod.txt">http://svn.parabola.me.uk/display/trunk/doc/nod.txt</a> which indicates that a turn restriction is in fact 3 nodes and 2 ways and at cgpsmapper documentation where they mention that you can have 3 roads restrictions using 4 nodes.<br>
<br>Taking a concrete example, I was wondering if relation <a href="http://www.openstreetmap.org/browse/relation/275622">275622</a>
  could be coded in the following manner in the NOD subfile:<br>NODES: <a href="http://www.openstreetmap.org/browse/node/62593962">62593962</a>, <a href="http://www.openstreetmap.org/browse/node/62593964">62593964</a>, <a href="http://www.openstreetmap.org/browse/node/62591266">62591266</a>, <a href="http://www.openstreetmap.org/browse/node/62591273">62591273</a><br>
WAYS: <a href="http://www.openstreetmap.org/browse/way/39800738">39800738</a>, <a href="http://www.openstreetmap.org/browse/way/41694496">41694496</a>, <a href="http://www.openstreetmap.org/browse/way/8731732">8731732</a><br>
<br>Unfortunately my knowledge of mkgmap/IMG file format prevents me of trying this but if someone wants to give it a try I would be happy to hear back from them.<br><br>  Thanks,<br><br>N.<br>
