okay - sounds great...
(as new devices do not really mind mkgmap:bicycle=no it does not matter
so much anymore - I'm only setting pedestrian restrictions different to
all others for my maps )

Hi Felix,
My current approach is to evaluate the results of the style, so it is
up to the author to decide what
a pedestrian-only way is.
Another point is that we don't need the check for ways which can't be
accessed
by bike. I am aware that these checks must be ignored when a special
cycling
map is created (or any other special map, we just have to find out
meaningful
option names)
I am trying to produce test data to find out in what case Garmin
prefers a small detour,
this should help to find concrete rules.

Subject: Re: [mkgmap-dev] sharp angles and routing
Well - what is a strict pedestrian only way? highway=pedestrian -
often can be used with bikes too (going slower)
highway=footway -- often still outside cities and used for mtbiking
though maybe not allowed.
highway=path & bicycle=no ---> very often nice mtbike trails in
countries where mtbiking is mainly forbidden like Baden-Wuerttemberg
or Austria.
And yeah - oneways could be excluded - but needs some care to not
exclude them (for cycling maps) if oneway:bicycle=no;
bicycle:oneway=no; oneway:bicycle=both; ( cycleway=* &
cycleway!=oneway ) would be the most common keys which mean cycling
against oneway direction is allowed.
For me excluding all ways that get tagged road-class=0 or 1, and
road-speed=0 could be excluded (but sometimes I use continue and
double ways so it exists with say road-class=4, road-speed=2 as well
as road-class=0, road-speed=0 in order to get me through sharp turns -
if the sharp angle fixing would work well - maybe I could drop this).

Hi Felix,
okay, I just try to find some criteria so that we find those nodes
+ arcs which really cause
trouble. A lot of sharp angles are between oneway roads which
don't allow traveleling
the sharp angle.
I think that also means that I can add code to ignore sharp angles
on pedestrian-only
ways.

Well - not in Pedestrian mode. I meant if you design a map with
road-class=4 as preferred way for pedestrians... Then of course
using a non pedestrian profile for routing so it chooses
road-class=4 or 3 preferably.
For Pedestrian mode chosen - there is no time penalty for sharp
turns - though I did not test if it would prefer ways that point
towards the destination at intersections.

Hi Felix,
please check:
you said that sharp angles also have an effect on pedestrian
routing,
I was not able to reproduce that. Can you give an example?
