<body class='hmmessage'><div dir='ltr'>Well, the problem here is, that even though OSMAnd says 'make a U-Turn', vshcherb says the following about it:<br><br>>>>>> <br>Technically this is not U-Turn, cause it goes to another OSM way.
U-Turn when you get back to the same road, because most of the roads are
drawn as 2 ways, that's why U-Turn is just a turn on the different
street. <BR>
There is no penalty based on the sharpeness of the turn, cause there
is no clear algorithm to say how much sharp turn is and what is the
penalty. <br><BR>>>>>><BR><br><BR>You can see the rest of his response to this at the GitHub ticket: <a href="https://github.com/osmandapp/Osmand/issues/1501" target="_blank">https://github.com/osmandapp/Osmand/issues/1501</a><BR><br><BR>-James<br><BR><br><div>> To: talk-us@openstreetmap.org<br>> From: niceman@att.net<br>> Date: Mon, 27 Jul 2015 13:20:50 -0400<br>> Subject: Re: [Talk-us] Am I mapping this wrong, or should the router be fixed for this?<br>> <br>> <br>> <br>> > 2) There should be some cost in a routing engine for making a u-turn so<br>> > as to discourage such routes even if there was an extra set of signals.<br>> > Making a u-turn does take time (one can not go from the posted speed<br>> > limit in one direction to the posted speed limit in the other direction<br>> > instantly).
