Hi, I wonder whether we could add a check that any highways joining onto a roundabout only do so at the end of way, and that no more than one way joins the roundabout at any given node? This would highlight roundabouts that do not adhere to the rule of having a separate node for each entrance and exit - I believe these cause the GPS to display the incorrect exit number when routing. I suspect this check would too complex to be done in a style file. Regards, Mike
Hi Mike, I think you cannot do those checks in the style. Do you have example cases for wrong exit numbers with the default style? Or with a style that I can try as well? I think I also saw this problem during my last cycling tour through Italy, but was too lazy to stop and note any details, in the meanwhile Minko changed the style rules for roundabouts, so I stoped thinking about it.

HI Gerd, at roundabout way 336004297, if you route from way 52026730 (Manor Court Street), which has a common point on the roundabout with way 208232611 (Newcastle Road), to way 48846175 (St. Thomas Place), BaseCamp says : 1. Manor Court Street, N53° 00.034' W2° 11.801' 2. Get on Manor Court Street and ride north, 0 m, 0 m, 180.0° true, N53° 00.034' W2° 11.801' 3. Enter roundabout Roundabout, 63 m, 9 s, 63 m, 9 s, 7.1° true, N53° 00.068' W2° 11.795' 4. Take the 1st left onto St. Thomas Place, 17 m, 13 s, 81 m, 22 s, 50.3° true, N53° 00.076' W2° 11.791' 5. St. Thomas Place, 22 m, 6 s, 102 m, 28 s, 0.0° true, N53° 00.087' W2° 11.786' Point 4 should be the 2nd left. I am using my own style, but do not think this will make any difference.

Hi Mike, yes, I can reproduce the problem. I just wonder if mkgmap can fix the problem as well, not only report it. Maybe it also depends on oneway attributes on the roads joining onto the roundabout. I'll have a closer look later.

Hi Mike, I've tried to collect special cases reg. this. I've seen places with a road going straight through a roundabout . I assume one is not allowed to enter the roundabout from these roads, but I don't know how this is correctly mapped. Such a road might be split into multiple OSM ways. The wiki about roundabouts doesn't mention this case, maybe because it isn't a roundabout in this case? Another problem: A way may not end at the roundabout, it may build some kind of v-shape only touching the roundabout. I think this is not correct mapping and should be flagged. Do you see others?

Do you have an example for this? I know examples, where you have a roundabout and a street going straight forward: cars have to use the roundabout, and trucks and busses are allowed to go straight through the roundabout in special situations. But then there should be access rules for this. Or the mapper forgot the bridge, since the street is going via a bridge above the roundabout.

Hi Thorsten, I just remember that I saw those cases, but don't remember where. I guess I can find one when I code the check and try it. What you describe sounds like what I saw.

Hi Gerd
I've seen places with a road going straight through a roundabout .
I know this one: http://www.openstreetmap.org/#map=17/54.53220/-1.53670 If you are going straight on the main road, you can use the direct crossing. Otherwise it works as a roundabout. ..Steve
Hi Steve, I wonder if these are really roundabouts. When you look at http://wiki.openstreetmap.org/wiki/Tag:junction%3Droundabout it says ".. and the traffic on the roundabout has right of way". I don't think that this is the case here?
