[mkgmap-dev] Question on routing difference

Mon May 30 17:09:20 BST 2022

Hi Jan,
I also get the same route as test-route-b_yes-removed.jpg with the latest OFM Germany from 10=05-2022
(website is finally up to date since today).
It only takes the Altengabengäßchen when you move the via point closer to the junction Altengabengäßchen,
or when you select "avoid toll roads". I really don't know why, because there are no bike routes on these streets.
What I use is routing over short distance. avoid nothing (sometimes unpaved).  Actually I don't use my Garmin at all,
I prefer Osmand with mobile phone (android) now 🙂

Cheers, Minko

Onderwerp: [mkgmap-dev] Question on routing difference

Hi all,

I´m using an altered copy of the OFM style and therefore sometimes compare the results.
One routing difference I found I was able to lead back, but the cause I don´t understand at all.

My test-route should prefer the small residential „Altengabengäßchen“ over the primary „Viktoriastrasse“.
Latest OFM does, my version not since I removed {add bicycle=yes} from this line:
highway=path & surface ~ '(paved|asphalt|sett|concrete|paving_stones|paving_stones:30)' & access!=no & access!=private & vehicle!=no { set highway=pedestrian; add bicycle=yes; add motorcar=yes; }

But unfortunately there is no path or pedestrian in the test-route, nor is it an option to use one.
Anyone has an idea how this path>pedestrian rule could affect routing on residential/primary?
Same happens when I replay the change with the original OFM.

Up-to-date osm.pbf, route from BC and screenshots are here: https://files.mkgmap.org.uk/download/556/test_route.zip

Thanks
Jan
