For me it's more that we already have a lot of cycle infrastructure
mapped which is constantly being updated and improved so if anything
TfNSW data should be treated as a guide only and not the only source of
information especially for indications of missing or removed cycle
infrastructure.Understandable! So far I've mostly been using it to "point out" infra on
aerial, and deal with some of the boilerplate tags. I don't think it
should be trusted over recent imagery or a survey that says something
*doesn't* exist.
cycleway:width on a cycleway=shared_lane doesn't make a lot of sense to
me, is that the road width? in which case it's just width=, or is it the
lane width?
I took a quick look through the data and a lot of the lanes and on-road
bits appeared to have the lane width rather than the road width, which I
guess makes sense because you're only interested in the lane as a
cyclist. A better tag would probably be width:lanes, but that needs
information I don't have in this dataset (other lanes, lane ordering,
etc.) and makes cycleway=shoulder a bit confusing.
Mappers using this should definitely check the width tags anyway, a lot
of them don't seem right to me.
After a quick scan it looks like a cycle route is marked as
cycleway=shared_lane, though generally I'd only add cycleway=shared_lane
if there is some kind of bicycle marking on the ground, is that reasonable?
I'd agree - that's what I thought was going on? I understand shared_lane
as when they paint a bike in the leftmost lane of a road, or in the
middle of an alley/small residential road.
With that said, TfNSW's definition - "On road facility type shared with
moving vehicles" - is a lot vaguer, so I wonder if they're tagging some
unmarked routes..
