<body class='hmmessage'><div dir='ltr'>Hi WanMil,<br><br>up to now I found these reasons for problems:<br>1) one error in the branch: via coords were replaced without updating<br>the corrresponding restrictions and the hash map<br>2) "no_u_turn" restrictions were not added <br>if from-way and to-way are equal. They are evaluated to be valid, but <br>I don't know if they really make sense? <br>3) restrictions are added to the restrictions hash map even if the via coord is <br>not contained in the bounding box.<br><br>4) restrictions that have a from-way or to-way which <br>is not added with a routable type or not at all,<br>e.g. way <a href="http://www.openstreetmap.org/way/225540783" target="_blank">http://www.openstreetmap.org/way/225540783</a><br>has no tags but is part of three restriction relations.<br>Another example:<br><a href="http://www.openstreetmap.org/relation/2880411" target="_blank">http://www.openstreetmap.org/relation/2880411</a><br>refers to ways that are tagged lane=tertiary<br>and the default style ignores them.<br><br>In high-prec-coords branch r3003 I've fixed 1) to 3), please <br>check again.<br><br>Gerd<br><br><br><br><div>> Date: Mon, 3 Feb 2014 13:01:40 -0800<br>> From: gpetermann_muenchen@hotmail.com<br>> To: mkgmap-dev@lists.mkgmap.org.uk<br>> Subject: Re: [mkgmap-dev] Problem with turn restriction<br>> <br>> WanMil wrote<br>> >> I want to make a small statistic why restriction relations become<br>> >> invalid.
