Yes ... The give way/stop is traffic management and while one may be able to determine the named through route, just from that, it may not work both directions. > How is the whole concept affected by roundabouts (mini) - where all '3' > arms are 'give way' That is perhaps one of my biggest gripes with routing software which simply ignores them, at least a cross the mini-roundabout would help rather than 'turn right at roundabout' which is actually half a mile further on :( But this is where what is the 'straight on' route may well not be clear even on the ground, and so if the road id changes then some additional tag is necessary. > What if the junction has more than one through route ?

Travel direction deals with the dual carriageway bit, but I can think of three mini-roundabout configurations I drive through regularly which OSMAND simply ignores, but have a total of three 'in' routes and one 'out' going one direction, but going the other direction is difficult to determine from the 'directions'. What is needed is proper lane directions through the junctions, rather than a 'left' or 'right' which are difficult even to decide when there is ALSO a road going across at 90degs :) 6 roads meet offset over two or three mini-roundabouts. -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
