<p>Won't work in the UK as there are plenty of cases where you have to give way and make a proper turn in order to stay on the same road name and/or ref. The concept even has a name - TOTSO which means "Turn Off To Stay On". </p>
<p>http://en.wikipedia.org/wiki/User:Martinvl/TOTSO</p>
<p>You cannot reliably infer from the geometry and name/ref which road (or lanes) has to give way. The only way to improve the navigation instructions is by giving hints.</p>
<p>This is not a routing question - nobody here is discussing which road is the best way to MyTown - it's about how you present the router's choices to the user.</p>

<div dir="ltr">As long as the name (or the ref/int_ref) of the street remains the same, I think the router should be able to give other messages than "turn right". There is no need for an additional relation IMHO.

The complaint is about 'extra' directions<br /> where the corner is actually the main road and the straight on branch is<br /> the turning. If the directions remain silent one would in some<br /> conditions get confused so the safe thing to do is announce both?<br /><br /> The correct wording of the the directions should be perhaps 'road bares<br /> right' and 'go straight on' rather than 'turn right' but that does need<br /> the perhaps missing "through_route" information? As I said, the<br /> inclusion of road names in OSMAND while useful at times does get<br /> similarly annoying when a 'continue on Axxx' would suffice. In this case<br /> the road id provides the "through_route" information ... one remains on<br /> the same road ... and the straight on road has a different one which may<br /> just be 'minor road'.<br /><br /> --<br /> Lester Caine - G8HFL<br /> -----------------------------<br /> Contact - <a href="http://lsces.co.uk/wiki/?page=contact">http://lsces.co.uk/wiki/?page=contact</a><br /> L.S.Caine Electronic Services - <a href="http://lsces.co.uk">http://lsces.co.uk</a><br /> EnquirySolve - <a href="http://enquirysolve.com/">http://enquirysolve.com/</a><br /> Model Engineers Digital Workshop - <a href="http://medw.co.uk">http://medw.co.uk</a><br /> Rainbow Digital Media - <a href="http://rainbowdigitalmedia.co.uk">http://rainbowdigitalmedia.co.uk</a><br /><br /> _______________________________________________<br /> talk mailing list<br /><a href="mailto:talk@openstreetmap.org">talk@openstreetmap.org</a><br /><a href="https://lists.openstreetmap.org/listinfo/talk">https://lists.openstreetmap.org/listinfo/talk</a></blockquote>
