[Talk-GB] Should highway=byway be deprecated?

2012-08-22 Thread Dave F.

Hi

is there an out of copyright source for the two different types of 
byway: restricted_byway  byway_open_to_all_traffic?
If not, as many are signed on the ground as just 'byway', I'm not sure 
highway=byway should be deprecated. How are users distinguishing what 
type they are?


Cheers
Dave F.

Here (Hampshire and surrounding counties), by what's on the ground: they tend 
to be signed as either byway or restricted byway.

I'd imagine that the same applies as for other public rights of way - in 
some places there may be something made available which is OK 
licence-wise; in other areas not.  There was an attempt a few months ago 
to try and rustle up a few more areas (on this list I believe).

There are two issues here.  One is whether highway=byway actually 
helps describe what sort of highway it is.  I'd argue that it doesn't, 
and that highway=service/track/something else as appropriate + some 
descriptive tags would be better, along with 
designation=byway_open_to_all_traffic.


The other is whether it makes sense to map something that's labelled 
byway as  designation=byway_open_to_all_traffic or 
designation=byway.  I've never yet found* something labelled byway 
that isn't actually a BOAT, so I haven't complained when people have 
come along and tried to standardise designation=byway to 
designation=byway_open_to_all_traffic.

I have seen Byway signs in Wiltshire in the past few months.

In Derbyshire they've also tended to be labelled byway but recently

 The other is whether it makes sense to map something that's labelled byway
 as  designation=byway_open_to_all_traffic or designation=byway.  I've
 never yet found* something labelled byway that isn't actually a BOAT, so I

 designation=byway to designation=byway_open_to_all_traffic.

Restricted Byways (RBs) are a fairly recent invention, as a
replacement for many former Road Used as a Public Path routes.
Previously the only official byway was a Byway Open to All Traffic
(BOAT).

Prior to the introduction of RBs, a simple sign of Byway wouldn't
have been unambiguous. Once the new type of byway was created, Local
Authorities will have had to be more careful with their signage.
Because of this, I would guess that any true Restricted Byways that
have had new signs put up would be signed as a Restricted Byway, and
any that haven't would still be signed as a Road Used as a Public
Path. Thus anything that is signed with just Byway can safely be
taken as a BOAT.

As an aside, note that it is not uncommon for a Byway Open to All
Traffic to be subject to a Traffic Regulation Order banning motor
vehicles during all or part of the year. The signs you'll typically
see in this case is a Byway fingerpost, and a No Motor Vehicles
traffic sign (a white circle with a red border, and a car and
motorcycle inside). While this downgrades the access rights to those
of a Restricted Byway, it doesn't alter the fact that the route is
technically still a Byway Open to All Traffic. In this case, I would
suggest tagging with designation=byway_open_to_all_traffic (since
that's what it is), adding appropriate access tags (eg
motor_vehicle=no) to give the access rights, and adding a note tag (eg
note=BOAT subject to Traffic Regulation Order) to explain the
discrepancy.

If cases arise where the mapper isn't sure what sort of byway a route
is, then I'd recommend designation=unknown_byway as a place-holder
tag, until the correct designation is determined.

Robert.

excellent, thnx

In the case of motor vehicles only being prohibited for half of the year, is 
there any consensus on the correct way to tag it?

Newer signs in Wiltshire do distinguish between byway and restricted byway. The 
former typically look like miniature road signs reading Byway whereas the 
latter have a purple border and explicitly say restricted byway.

It varies depending on county but as I said earlier most counties round here do 
seem to distinguish. Unknown byways are often signed as right of way or 
public right of way, and West Sussex signs ORPAs now as plain Public Way !

Yes, that reminds me I need to update some byways around Avebury...
[e.g. http://www.openstreetmap.org/browse/way/25793851]

I think the idea is to use the syntax from 
http://wiki.openstreetmap.org/wiki/Opening_times

So I think for example only in summer months:
motor_vehicle=Apr 01-Sep 30

As to whether any data consumer will be able to decipher it, is another 
question
