[mkgmap-dev] Roundabout checks

Wed Jul 27 13:16:14 BST 2016

I have rebuilt this area of the map with the default style, and the result
is the same.

Regards,

Mike

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.

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.

Gerd

Betreff: [mkgmap-dev] Roundabout checks 

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
