[mkgmap-dev] Incorrect runabout exit indication

Sat Oct 4 07:29:00 BST 2014

Hi Minko,

thanks for the info. I am pretty sure that this "trick" is the cause of the problem,
but I am not sure if mkgmap can be improved to handle it.

If I got it right, the additional roads with access=no are also handled by the adjust-turn-headings
option, so maybe they are only causing trouble here.

I don't know if (or how) I can configure my Oregon to show the problem, so I've created more
test maps for Johan:

v3: java -jar mkgmap.jar --route --index --gmapsupp --style-file=d:\mkgmap-style-sheets-read-only\styles\world wrong-exit.osm
v4: java -jar mkgmap.jar --route --index --gmapsupp --adjust-turn-headings --style-file=d:\mkgmap-style-sheets-read-only\styles\world wrong-exit.osm
both with the original style files .

v5: java -jar mkgmap.jar --route --index --gmapsupp --style-file=d:\mkgmap-style-sheets-read-only\styles\world wrong-exit.osm
v6:
 java -jar mkgmap.jar --route --index --gmapsupp --adjust-turn-headings 
--style-file=d:\mkgmap-style-sheets-read-only\styles\world 
wrong-exit.osm
both with a modified lines file (removed the "continue with_actions" for the roundabouts)

@Johan: Please check all 4 versions

> junction=roundabout & highway=trunk [0x0c road_class=3 road_speed=2 resolution 18 continue with_actions]
> junction=roundabout & highway=primary [0x0c road_class=3 road_speed=2 resolution 19 continue with_actions]
> junction=roundabout & highway=secondary [0x0c road_class=2 road_speed=2 resolution 20 continue with_actions]
> junction=roundabout & highway=tertiary [0x0c road_class=1 road_speed=1 resolution 21 continue with_actions]
> junction=roundabout & highway=unclassified [0x0c road_class=1 road_speed=1 resolution 21 continue with_actions]
> junction=roundabout & !(highway=unclassified|highway=tertiary|highway=secondary|highway=primary| highway=trunk) [0x0c road_class=0 road_speed=1 resolution 22 continue with_actions]
> 
> 
> Second step, all roundabouts are made unaccessible after 0x0c is processed, in order to prevent two routable lines on top of each other:
> 
> junction=roundabout {set access=no}
> 
> 
> Third step (continue with_actions) the highways are rendered, so you can see a difference in road classes on those roundabouts.
> The default mkgmap style (=Lambertus 'old style') renders all roundabouts the same.

> I think Johan's nuvi gets confused by those two routable types?
