[talk-au] Tagging Trucks (hgv) "Use low gears"

[Andrew Hughes]

Hi Ben, Andrew, Graeme,

Agree 100%, the hazard is the "steep descent" (or similar), which most
likely (but not always) coincides with the include/gradient sign such as
"15%" (and we might see "incline=-15" tag used as well).

possible tags are:

hazard=Descent  <-- because this is applicable to not just trucks!
hazard=Steep Descent  <-- because this is applicable to not just trucks!
hazard:hgv=Descent
hazard:hgv=Steep Descent
hazard:hgv=Steep Descent;Tilting


incline=-15
incline:forward=-15 <---- if you want to specify direction or is this
implicit in just using incline and direction of the way anyway????



The "restriction" (assume that is the common OSM term Andrew?) or signage
on the road is to use low gears.  Q: Tagged on a node and/or  way?

What about

traffic_sign:hvg=Use Low Gears
traffic_sign:hvg=AU:Use Low Gears
traffic_sign:hvg=Tilting
traffic_sign:hvg=Use Low Gears;Tilting


Feedback is most welcome

Would anyone like me to create a mapillary challenge so we can tag a few of
these examples?

Cheers,
Andrew
