Re: [Talk-us] Trunk

2017-10-15 Thread Martijn van Exel
Okay folks. Coming back from not even 48 hours camping and this thread has
exploded. I don't think it benefits anyone to continue in this way.
Valuable insights get lost in the sheer volume of email; arguments are
being repeated.

I am dedicating the next Many Mappy Minutes (our monthly-ish online
hangout) to discuss road classification. I proposed November 15 5:30 PT in
an earlier email to this group. I invite you all to join then.

In the mean time, if you would like to have a more interactive discussion,
please join IRC or Slack and continue the discussion there.

Re: [Talk-us] Trunk

2017-10-15 Thread Nathan Mills
In the US, we've always treated primary/secondary/tertiary as a way to tag 
importance to the road network, while physical construction was secondary. 
Motorway, of course, was and still is treated differently. Trunk has always 
been stuck in the middle between people who like me and Paul want to use it 
more like motorway but for divided highways and people who want it to mean more 
primary than primary.

That's why we're still taking about it now, long after the usage of other 
highway tag values has long been settled. The closest thing to a decision that 
was ever made was NE2's unilateral mass edit, some of which has been reverted, 
some of which hasn't. Without consensus that the tagging is wrong and not just 
the unilateral decision, I'm not going to go out of my way to revert his trunk 
changes on ways I'm not otherwise editing large portions of. It's not a nice 
thing to do. It's got nothing to do with thinking that things should be that 
way and everything to do with not being a jackass who unilaterally imposes 
their will on the whole community.

Re: [Talk-us] Trunk

2017-10-15 Thread Nathan Mills
Yes, on more than one occasion back in the mists of time before armchair 
mappers had spread the lanes and other condition tags widely I found some 
pretty shitty US highways labeled as trunk, not because they are better roads, 
but because they happen to be long distance through routes. US412 should not be 
trunk across most of the state of Arkansas. It's mostly a crappy winding route 
that is actively dangerous for trucks, who should be taking I-49 to I-40 or 
US71 north to 44 unless their destination is directly along the route.

By the network definition, it solidly deserves trunk, but by any other measure 
it does not, and calling it so drives traffic to places it shouldn't be and 
makes the map harder to use effectively at a glance.

Yesterday(ish) someone asked which maps differentiate expressway vs freeway vs 
everything else that is paved in their inking styles. I'll answer that with a 
question. Have you ever seen a US paper map? Until the digital road atlases 
with topo shading and/or overlays started becoming common in the late 90s 
basically every official state highway map, chamber of commerce map, gas 
station map, and road atlas differentiated divided, limited access, undivided 
paved, and unpaved with styles and paved/unpaved with weight. Sometimes you'd 
get numbered highways in red and other roads in black (with light grey or 
dashed lines to mean unpaved, depending on the map)

It's long been how US road maps are drawn, so map users here expect that 
differentiation to exist. Of course, we also expect toll roads to be colored 
green, but OSM doesn't do that either. (And I'm fine with that, TBH. I don't 
consider it as important as being able to differentiate between divided and 
undivided in a relatively simple way.)

If someone could explain why primary is insufficient to denote a paved rural 
road that connects minor population centers far from other routes. Why should 
US-71 south of Witcherville in Arkansas not be tagged as primary once the 
divided segment ends? There aren't many US highways of that size with more 
traffic, but it seems solidly primary to me. Some might make the whole thing a 
trunk since the route goes through several states and is important enough to be 
being replaced as money becomes available with I-49. Never mind the four plus 
hours of driving through little towns on a windy mountain road involved. I'd 
have gotten in an edit war over it if someone had tried to tag the part north 
of I-40 a trunk before the freeway was built to Fayetteville and beyond.

Just for information, if you wanted to adopt the UK system in the US, you
could do that absolutely trivially by defining highway=trunk as those
(non-motorway) roads within your National Highway System. That's pretty much
analogous to how it's used here in the UK.

Because we can't.

WA-290 at Starr Road is two paved lanes wide, with 12-foot lanes and
4-foot paved shoulders.  It has a speed limit of 45 mph.

WA-261 at Lyons Ferry Fish Hatchery is two paved lanes wide, with
11-foot lanes and 4-foot paved shoulders.  It has a speed limit of 50
mph.

Two very similar-looking roads, so they should have similar
classifications, right?  WA-261 runs from nowhere much to nowhere
much, and sees maybe 300 vehicles a day.  In contrast, WA-290 is the
other major route between the Spokane and Coeur d'Alene metropolitan
areas (the main route is the interstate), and sees 13,000 vehicles a
day go by.  If you omitted WA-261 from a map, almost nobody would
notice.  If you omitted WA-290, people would discard your map as
useless.

I've driven both roads, and they *feel* very different.  But it's not a
difference that I can put into numbers -- at least, not without putting
a traffic counter out for a few days.

Re: [Talk-us] Trunk

2017-10-15 Thread Paul Johnson
Not entirely a bad idea, but runs fundamentally in to the same issue this
thread is about, if not moreso.  FM 2161 would wind up as a more
significant road than OR 22 in such a scenario.  Never mind that OR 22 on
the west side of Salem, OR is a major 50 MPH expressway going directly to
the core of Oregon's capital as an expressway leading west from the
Willamette RIver to OR 99W.  FM 2161 is a 70 MPH road best known for part
of it being US 66 before 1988 when US 66 was retired.  I'd still consider
OR 22 as a trunk.  The old_ref=US 66 portion of ref=FM 2161 would be a
judgement call on primary, even if I'd consider most Texas Farm to Market
routes as unclassified or tertiary; it's extremely strong historical
significiance would be what brings it to as high as secondary or primary in
my mind, despite being literally of the same design and barely less
significant than US 97 for most of it's length.
