Having retagged some roads in my area as a result of some changes to
road layouts, I noticed that my Garmin was routing me over a bit of road
which I had tagged "motor_vehicle=no". The road is signposted with the
usual "No Motor Vehicles" sign (red ring containing a car above a
motorcycle) which, according to both the NL and general wikis should be
tagged as "motor_vehicle=no". This is also supported by the fact that
Potlatch2 includes an easily accessible facility to set this tag.
Having browsed through the source and the style files I could find no
reference to the motor_vehicle tag, which surprised me a bit... Anyway I
fixed it for me by adding a single instruction to the "lines" file:
# add support for motor_vehicle
highway=* & motor_vehicle!=yes
{add access='${motor_vehicle}'; add foot=yes; add bicycle=yes; add
mofa=yes; add moped=yes; add horse=yes}
This handles motor_vehicle=no and motor_vehicle=destination ("except for
access" in the UK for example). I assume "motor_vehicle=yes" (don't know
when one might use this) will work properly anyway.
The moped and mofa tags reflect the rules here in NL, where these
vehicles are not counted as motor vehicles for the purposes of this
sign. If these subtleties are different in other countries, it can
easily be adapted by referencing mkgmap:country.
Is this a reasonable way to do this? If so, could it be added to the
standard mkgmap distribution?
Best regards,
Colin Smale
