Hi Thorsten,
the road speed assignment of a road is performed as follows:
1) Use road_speed from the element definition (7 in your example)
2) If mkgmap:road-speed-class is set use this value instead
3) If mkgmap:road-speed is set use this value instead if it is a number
only. If it starts with + or - modifiy the value retrieved in 1) and 2).
Also limit this value to mkgmap:road-speed-min/max if applicable.
So for your example road speed=4 is used for a motorway with maxspeed >
60kmh. Road speed=7 is used for all motorways with no maxspeed or
maxspeed <= 60kmh.
As you can see road_speed in the element type definition works as
default value. It is not possible to check if the road_speed is set in
the element type definition.

Hi,
I have a question about mkgmap:road-speed-class and the
road_speed/road_class elemets.
The documentation only writes that "mkgmap:road-speed-class"
overrides "road_speed".
But if I use "road_speed", what does this mean for
"mkgmap:road-speed-class"?
Example:
highway=motorway [0x01 road_class=4 road_speed=7 level 3]
maxspeed=* & mkgmap:road-speed-class!=* & maxspeedkmh() > 60 { set
mkgmap:road-speed-class = 4 }
Will the second rule overwrite the first one?
If yes, how can I check if road_speed was already set or not?
If not, will the second rule have ever any affect?
This construct is used in the default mkgmap style, setting
road_class/road_speed in the action block, and later according
to maxspeed in inc/roadspeed.
Thanks,
Thorsten
