[Talk-us] [Talk-US] tagging rumble-strip-separated road shoulders

[Volker Schmidt]

Last fall I travelled by bike the ACA Route 66 westbound. Long stretches
are on freeway/trunk shoulders.
I think I know how to map shoulders:
highway=motorway|trunk
oneway=yes
shoulder=right
shoulder:surface= ...
shoulder:width= ...
shoulder:smoothness ...

In the case of undivided roads:
highway= ...
oneway=no
shoulder=right|left|both
shoulder:surface= ... OR shoulder:right:surface= ... OR
shoulder:left:surface=
shoulder:width= ... OR shoulder:right:width= ... OR shoulder:left:width=
shoulder:smoothness ... OR shoulder:right:smoothness= ... OR
shoulder:left:smoothness=

Two questions arise:



*(1) How to tag the bicycle access:*
on the highway with bicycle=yes
or restricted to the shoulder with the lane= tag: lane:bicycle=no|no|yes
(in case of a two lane-plus-shoulder highway.
Problem with the bicycle tagging on the shoulder only is that bicycle
routing algorithms won't route you across access ramps, which are
implicitly bicycle=no.
In fact there is even a legal problem there: many freeways have signs:
"bicycle use shoulder" which you cannot obey at the ramps.

(2) how to tag longitudinal rumble strips,
(situated between motorized-traffic lanes and shoulders, example: [1], not
the "sleeping policeman" type that goes across the road nd which is
normally tagged as traffic_calming=rumble_strip on a node of the highway)
To tag their presence is important because they represent an augmented
protection of cyclists on the shoulder from cars invading the shoulder by
mistake, i.e. reduced risk of being killed.
To note that I have encountered rumble-strip-separated shoulders also on
roads below the rank of trunk or motorway
