<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Hi all,</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; "> </p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">I'm working on adding turn:lanes to roads at traffic lights, and am also working on adding support for reading turn:lanes in OsmAnd (Android). I'm wondering on how to mark turn:lanes in the case of an implied right turn. For example, let's say that you're approaching a traffic light and there are four lanes heading in your direction. The left-most (1st) lane is indicated as a left-only lane. The second, third, and fourth lanes are unmarked (therefore, it would be <span style=" font-family:'courier new';">none</span> for these lanes). This would mean that the second and third lanes are straight-only, and the fourth lane is straight and right (let's assume a right-turn is allowed here).</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; "> </p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">In this scenario, would this be marked as <span style=" font-family:'courier new';">left|none|none|none</span> or <span style=" font-family:'courier new';">left|none|none|through;right</span>, and if it's the former, would data consumers have to infer from the turn restrictions and see that a right turn is allowed there?</p>
