Warin, I agree with your point about being able to tag the turn restrictions, and the solid white line.
I think the main issue is that the node where the ways diverge is a significant distance from where the line become solid. If fact, the node is near the beginning of the dashed line. If the divergence of the ways was placed nearer to the commencement of the solid white line, this would maintain the ability to implement turn restrictions, and clean up the intersection. Lane tagging is also recommended, prior to the divergence of the ways, so that supporting navigation aids can advise the driver appropriately. Does this work for you, Petra/Telenav? Also, Petra, your image of the WA intersection is more in-line with what I believe should be mapped in that instance, and is in line with my earlier comments. Does anyone else have further suggestions on the Canberra intersection?
