<body class='hmmessage'><div dir='ltr'>Hi,<br><br>just to let you know: I am able to reproduce the results with your data.<br>Not sure what happens with the mergeroad map. MapSource finds<br>the shorter route when you select to minimize the distance,<br>and (depending on the speed settings), it even may calculated<br>the shorter time for the shorter route. <br>For both routes I see a list with 7 hints, so the only explanation<br>that I have is that MS prefers routes where don't have to <br>change roads often within a few meters.<br><br>Gerd<br><br><div>> Date: Sun, 29 Dec 2013 10:44:24 -0800<br>> From: franco.bez@web.de<br>> To: mkgmap-dev@lists.mkgmap.org.uk<br>> Subject: [mkgmap-dev] mergeroads sometimes breaks routing<br>> <br>> I found a very strange routing behaviour connected to the mergeroads-patch.<br>> The Problem area is here:<br>> http://www.openstreetmap.org/#map=17/47.89307/10.63390<br>> <br>> When I try to route ( Automobile-mode, minimize-time ) from corner<br>> Liegnitzer-Straße/Glogauer-Straße to Beuthener-Straße Nr. 11, I get routed<br>> all the way round the block.<br>> <br>> Using --x-no-mergeroads the routing is fine.<br>> <br>> Even stranger, when I tried to assemble a small testcase with an<br>> data-extract from JOSM, the routing is fine, even when using mergeroads.<br>> <br>> So the error seems to be triggered by something specific to the tile that<br>> was generated when building a map of Bayern.<br>> <br>> See screenshots:<br>> <br>> Bad Routing with mergeroads:<br>> <br>> <http://gis.19327.n5.nabble.com/file/n5791132/mergeroads-9452.bmp> <br>> <br>> <br>> Routing OK with --x-no-mergeroads:<br>> <br>> <http://gis.19327.n5.nabble.com/file/n5791132/no-mergeroads-19995.bmp> <br>> <br>> <br>> <br>> --<br>> View this message in context: http://gis.19327.n5.nabble.com/mergeroads-sometimes-breaks-routing-tp5791132.html<br>> Sent from the Mkgmap Development mailing list archive at Nabble.com.<br>> _______________________________________________<br>> mkgmap-dev mailing list<br>> mkgmap-dev@lists.mkgmap.org.uk<br>> http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev<br></div> </div></body>
