highway=cycleway + access=no + bicycle=NULL is used for routing about graphhopper

Currently we are treating access=no and vehicle=no the same way with allowing this segment for bicycles. But according to https://wiki.openstreetmap.org/wiki/Tag:access%3Dno the intention of access=no is stronger. While on a segment tagged as vehicle=no it is still possible and legal to dismount and push for access=no this is not the case. So I think that this problem report is valid and we should change it. I'm going to prepare a PR if there aren't any objections.

Have also thought about this like using foot_access in a custom model as exception when bike_access is false but there are several cases where is does not work like for steps or bad surfaces or a too big hike_rating (sac_scale) etc.

See discussion in #870. Maybe @ratrun can comment on this.

Anyway, the discussion about the tagging above is valid. I'm going to prepare a change to accept highway=cycleway toghether with vechicle=no. We should allow this for bicyles. Cycleways under construction should be tagged with with highway=construction

Access parsing aside, the road isn't tagged properly IMHO. This should be highway=construction + construction=cycleway as explained in the OSM wiki:

https://wiki.openstreetmap.org/wiki/Tag:highway%3Dconstruction#How_to_map_the_start_of_a_road_repair_or_reconstruction

And should we remove the special case way.hasTag("highway", "cycleway")) in BikeCommonAccessParser? And then consider the "dismount" for vehicle=no in OSMGetOffBikeParser and BikeCommonAverageSpeedParser?

I extended the check there in my first version of the PR, see #2981

And then consider the "dismount" for vehicle=no in OSMGetOffBikeParser and BikeCommonAverageSpeedParser?

Yes that is a good idea. I'll try to extend the PR.

Broadly speaking, we should do this for all cases where foot access is allowed but biking isn't.
