[GraphHopper] Bicycle navigation on separate cycleways

[Peter]

Hi Marc,

off-the-list you have posted this example:
https://graphhopper.com/maps/?point=53.077057%2C8.836741&point=53.076918%2C8.836613&vehicle=bike&elevation=true&layer=Lyrk

> As we add more detail to OSM, people start to draw them as separate lines

That is a tough problem.

If there is only a distinct connection from cycleway to the main street
you should map it as one or more connecting streets. If there is a free
and accessible area between the cycleway and the main street and this
area can be crossed by bike or (only) foot you should map it as such.
Although we currently do not support area routing, it should not be that
hard to add: https://github.com/graphhopper/graphhopper/issues/82

Do you have a link to that schema?

Regards,
Peter
