There isn't a standard way - make something up! If you can get
critical mass (ideally by going via the "proposed features" page on
the wiki to get it on the Map Features page) it will eventually be
used by the renderers and anything like route planners than use the
OSM data. carpool=something would be obvious, but i've no idea
how these things work, so I don't relly know what the something
should be!
In general, the only accepted tag for marking things that change
depending on the time of day is the access key
<http://wiki.openstreetmap.org/index.php/Key:access> but this isn't
actually sufficent for your examples or many others - and this is
fairly well accepted. If you can come up with a system that covers
your examples, then you've done pretty well!
Good luck!
