Dear all,

maybe you could help me, as I did not find hints on the internet.

I wonder if it is possible to have different road_speeds for different vehicles in one map.

Background:

Currently I have one map for car use on my device and a second one for vacation when travelling with the caravan. The second map has lower road_speeds as I’m not that fast with the trailer.

To save tiles and memory, the second map is quite reduced (less points, also less minor streets, tracks, etc).

For compiling and memory reason I would like to merge the speed aspect into one map.

Would it be possible to have something like

   highway=* & type.equals("motorcycle") { add mkgmap:road-speed = '-2' }

An additional aspect to consider would be that this command would be needed multiple times, as from my experience it is not possible to do „-2“ in general. Also there would be an issue with minor roads, that have a low road_speed, as it might get negative.

Any hint is greatly appreciated. If it is not doable at all, tell also ,please.

Thanks, Michael
