### Profiles for country differences
Some countries have differing access rules for different transport types. (https://wiki.openstreetmap.org/wiki/OSM_tags_for_routing/Access_restrictions). Profiles countrycar, countrybicycle and countryfoot may be used as starting points for country support. Country Specific location data (geojson geometry) should be provided to the osrm-extract for example:
osrm-extract --profile ../profiles/countryfoot.lua --location-dependent-data ../data/osmb.geojson
osrm-extract --profile ../profiles/countrybicycle.lua --location-dependent-data ../mygeojson/Netherlands.geojson
## Processing flow
It's important to understand that profiles are used when preprocessing the OSM data, NOT at query time when routes are computed.

### Profiles for country differences
Some countries have differing access rules for different transport types. (https://wiki.openstreetmap.org/wiki/OSM_tags_for_routing/Access_restrictions). Profiles countrycar, countrybicycle and countryfoot may be used as starting points for country support.
To enable support add 'countryspeeds' to the uselocationtags Set. e.g.
uselocationtags = Set
{
'countryspeeds',
}
Country Specific location data (geojson geometry) should be provided to the osrm-extract for example:
osrm-extract --profile ../profiles/countryfoot.lua --location-dependent-data ../data/osmb.geojson
osrm-extract --profile ../profiles/countrybicycle.lua --location-dependent-data ../mygeojson/Netherlands.geojson
If you enable the tag but provide no location-dependent-data the profile will use the 'Worldwide' profile. (https://wiki.openstreetmap.org/wiki/OSM_tags_for_routing/Access_restrictions#Worldwide)
