[OSM-talk-be] integrated Routeplanner GraphHopper on osm.org strange result

2018-08-01 Thread Jakka

On the bridge that was closed since march 2018 ...
tag was set to access=no
routeplanner selector bicycle goes true it, on foot detour,
car correct impossible highway=cycleway

Is there a place to report this behavior ?

Hi Jakka,

I suppose it is related to this issue:

https://github.com/graphhopper/graphhopper/issues/1215
(that is the correct place to post errors of this kind I think)

I think Graphopper allows this to happen because NOT doing so would be a
bigger error. It often happens that the authority that defines the cycle
route does not communicate with the authority that defines access for
bicylces, and then you get situations where you can't drive into the street
you have to ride into. Example:

https://www.openstreetmap.org/way/202425978#map=18/50.75460/3.72778

I would suggest reclassifying the road to highway=construction +
construction=cycleway. Given the description in the Note, that seems to be
more correct than the current tagging.

Want the controle other locations of the strange behavior of routeplanner.
What the overpass code for the full access=no without something else 
like foot=yes or bicycle=yes ecetera ?

As simple as this: way["access"="no"][!"foot"]
The !foot part means "there is no foot=* tag present".
Example: http://overpass-turbo.eu/s/AJy

Of course, nodes can also have an effect on routing. For example, you could
add the code below to query barrier nodes which have an access tag but not
a foot tag.

node["barrier"]["access"][!"foot"]
