In London some of our
bus-only lanes (just a red painted and signed lane on the normal carriageway) are 24 hour but many are available to other traffic off-peak.

I am very interested in this - does anyone think that this principle could
be extended to optimizing the use of BRT rights of way to allow buses to
enter and leave at various points without causing congestion?
