I'm not sure anymore. There was a time when a Basecamp update and device firmware updates meant that all restrictions were simply ignored. I think newer Basecamp version corrected that bug again however (Garmin claimed on their forums such restrictions never existed - so maybe they really did not use them in their maps?). I'm not sure for the devices though - Got not much time right now - but I can check with my devices in September (Oregon 600, etrex 30 - Vista HCx was never affected by that bug).

Toll and Unpaved have never been affected either and are really avoided if set so.

Hi Felix,

can't believe that Garmin ignores it, can you prove that with the default style?
If not I assume that you create multiple arcs and one allows cycling.

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.

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?
