[mkgmap-dev] Questions about carpool handling

Thu Dec 5 21:48:58 GMT 2013

So in the mergeroad branch the mkgmap:carpool tag will be totally independent of access=yes/no?
This will be a big improvement because carpool avoidance will be one of the few instruments to block a road for traffic (access=no, bicycle=no etc are ignored by Garmin).

Since Garmin sets this flag in the bicycle mode automatically on, I can use it in the style file to match bicycle=no with mkgmap:carpool=yes. At the moment this is not possible because it is connected with access=no and motorcar=no.
