Re: [Tagging] Center Turn Lane Tagging?

2014-07-21 Thread Paul Johnson
I'm at a loss to remember where I saw this, though, it looked like your
standard American both-way left turn lane, though it had an additional
token set of orange dots down the middle.  Most drivers would cross over
the nearest lane to the lane adjacent to oncoming traffic to be able to see
their turn.  It was a particularly wide boulevard.

 I don't recall seeing that and am having a hard time imagining how it

Just tag it as the both_ways model; unless I'm missing something.  NE2 is
good at finding minutae, but often finds poor ways to tag things in a
consistent manner (most glaringly, a mass retag of all US highways as trunk
instead of primary, even when undivided).

 lanes:both_ways=1
 turn:lanes:both_ways=left

Well, both_ways, was only a proposal and was even not included in style
and preset for a long time. Both still do not support it completely.

I have to say, that I did cheat a bit and did count forbidden middle
lanes to one direction, so far, which might be another reason for low
numbers.

Reworking the preset is on my TODO list but I have difficulties to
include all tags in a practical way without inflating it even further
and it already does hardly fit on small screens.

As I personally mostly use the style and only need the preset for auto
completion, e.g. I am not familiar in terms of usability and would be
happy about some comments and/or suggestions.

Re: [Tagging] Center Turn Lane Tagging?

2014-07-20 Thread James Mast



I personally think that 'centre_turn_lane=yes' is a good tag.  It cuts down on 
a ton of extra tags where that might be confusing to new and experienced users.

Plus, this way you shouldn't need to add an extra 'lane' to the lane count, 
making routers think there's more lanes that aren't really 'used' that often 
unlike a dedicated turn lane for one direction at an intersection where it is 
important.

Seriously, isn't this simpler,

centre_turn_lane=yes
lanes=2

than this for Center Turn Lanes?

lanes=3
lanes:both_ways=1turn:lanes:both_ways=left

Simpler, and to the point my example.  All the routers would have to do is tell 
the user to enter the 'Center Turn Lane' to make their left (or right in 
England) turn when the way has that tag.  Especially with highway signs all 
around calling it a 'Center Turn Lane'.   It's just common sense here.  I mean, 
if you really want to we could count the lane in the lane counts, but the 2nd 
example doesn't fully work since sometimes, you do need that lane to turn 
'right' and get into the main lanes when coming out of a business if there is 
heavy traffic going the way you need to go.  I know some states frown on doing 
that, but most understand that needs to be done sometimes.

And another note here, I don't think you should really be attacking people here 
on-list when they can't defend themselves, Paul.  It just isn't right and not 
fair.

What if there's more than one lane that's both ways allowing left turns?
