That simplifies the question a lot.

The tag "cycleway=lane/track" already implies that the use of the cycle way is compulsory.
If there is no cycle way, you can add cycleway=no, so that routers know that it's OK for bicyclist to use that road and fellow mappers know, that it has been checked. Though, this practice is highly disputed.

And in cases of a separate drawn line (case 3. segregated foot and cycle ways) just add "bicycle=use_sidepath" to the road way. 

OR don't tag any cycleway=* on the road. (yes, that levees some uncertainty, see above.)  A separate way tagged with "highway=cycleway" OR "highway=path + bicycle=designated + segreagated=yes" should be interpreted a compulsory.

Yours Hubert.
