[mkgmap-dev] opposite-cycleways option

Tue Feb 9 16:51:59 GMT 2021

HI Joris,

I do not think we should be hard coding non-standard tags into mkgmap, even
if there are a number of them in some countries.

cycleway:left=opposite, cycleway:left=opposite_lane and
cycleway:left=opposite_track are all non-standard and to me don't make any
sense.

I suggest you add something like
cycleway:left=opposite | cycleway:left=opposite_lane |
cycleway:left=opposite_track | cycleway:right=opposite | cycleway:right
=opposite_lane | cycleway:right =opposite_track { add cycleway=opposite } to
your lines file if you want to use them.

Cheers,
Mike

Hi Gerd,

Indeed short way of saying cycleway:left=opposite_lane or
cycleway:left=opposite_track
Like you have 
cycleway=opposite |
cycleway=opposite_lane |
cycleway=opposite_track |

I would also think the others are enough but when I checked taginfo it is
more commonly used then cycleway:left=opposite_track 
So seems valid to me...

Hi Joris,

I just wonder what cycleway:left=opposite means. Same with the already
supported cycleway:left=opposite_lane. Do you know a place where this makes
sense?

Gerd

Hi Gerd,

I came accross tagging
        cycleway:left=opposite
        cycleway:right=opposite

Overpass says that there are about 3200 ways in France/Belgium for this
situation

These are not mentioned in your e-mail post as possible tagging to create
synthesize roads, if I'am correct Would it be possible to add these options?

Mentioned in your post
oneway:bicycle=no |
bicycle:oneway=no |
cycleway=opposite |
cycleway=opposite_lane |
cycleway=opposite_track |
cycleway:left=opposite_lane |
cycleway:right=opposite_lane |
cycleway:left=opposite_track |
cycleway:right=opposite_track

Met vriendelijke groeten,

Hi Joris,

the java code creates a copy of the original way and removes various
possibly existing access tags, it sets access=no,
bicycle=yes,oneway=no,mkgmap:synthesised=yes

I would not add foot=* as the original might have something equivalent to
foot=no.
In fact there should be no need for any special handling in the style unless
you want to assign a special typ.

Gerd

Hi,

I'm trying to improve routing for my bicycle and the oneway allowed for
bicycles by using the --make-opposite-cycleway option But I was wondering
what the criteria are for creating such extra cycleways.
I have read some earlier posts an 'll found Gerd's  comments on
http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2014q2/020818.html

But the manual does not state what is actually implemented. Is there some
more documentation somewhere?

As far as I understand now

  *   Only if a highway has oneway=yes AND (some variants of oneway:bicycle
= no) then
  *   Mkgmap will create an extra highway line with (mkgmap:synthesised =
yes)
  *   Within my style file I'll pick up the mkgmap:synthesised=yes and
assign an "invisible overlay routeable highway" line and then
     *   Remove the oneway-tag (which applies to cars)
     *   set mkgmap:bicycle/foot=yes
     *   set mkgmap:car/hgv/bus/delivery=no

Is that correct?
Thx for helping me out
