# Define the access restrictions
# The following tags define the restrictions:
# mkgmap:bicycle
# mkgmap:foot
# mkgmap:car
# mkgmap:truck
# mkgmap:taxi
# mkgmap:bus
# mkgmap:emergency
# mkgmap:delivery
# A class is not allowed to use the way if its tag is set to 'no'

# First set access settings with high priority.
#
# In case a way is tagged with 
#    highway=motorway;access=yes 
# we assume that foot and bikes are not allowed anyhow.
