Is it not possible to simply call the bus lanes either full time
or part time and have full times ones painted red and part times
ones painted green and have only one possible part time option?

You can't do the latter because some are tidal and others weekdays
only or Mon-Sat. What we really need - though the cost would
probably be too high - is red runway-style lights demarcating bus
lanes which are turned on when they are operational.
