About the "green wave", it could be modelized with another relation
(or super-relation) grouping of traffic signals and the direction of
the wave. After all, this is also what is happening in the real world
where such wave is only possible when the concerned traffic lights are
synchronised by one machine.
Defining different "phases" on day time or night time is outside of my
proposal for relations.

But another point is traffic signals where a bicycle can ignore red
light stop when he is turning to right (right-hand traffic). This is
allowed in some coutries, sometimes only with a specific road sign. I
don't know how it is tagged currently.
