Hi Johann,
The attached patch improves the handling of access restriction tags so that you can now restrict on a vehicle class basis i.e. hgv=no
With a short glance at your patch I've seen that the keywords are contained in the sourcecode. Shouldn't it be in defined in the style file?
As far as I can see, at the moment there is no possibility to define default restricitions for different tracktypes. I would propose further keywords in the lines file, e.g.
highway=cycleway [0x0a road_class=0 road_speed=1 *access=bycycle,foot* resolution 21]
or
highway=cycleway[0x0a road_class=0 road_speed=1 *access_bycycle=yes access_foot=yes* resolution 21]
The most recent version of my code now pays attention to these OSM tags: access, bicycle, foot, hgv, motorcar, motorcycle, psv. Unfortunately, the Garmin codes don't appear to know about motorcycles (they lump motorcycles and cars together) or horses (or taxis, either). So if a way is tagged with one of those, i.e. hgv="no", the gps will know about it. If this is not adequate, we can look into adding extra information in the style file. Cheers, Mark
