Also, what do the sXX numbers next to bus routes mean on the electronic bus time boards at bus stops? Like bus 64 to federal plaza, s23 s55 etc.

The "s" stands for "scheduled." It means that, instead of giving you a real time arrival estimate, it's the time left until the bus should arrive according to the posted schedule. The "s" turns up when the tracking system has lost communication with the bus, or the bus has lost its GPS connection, etc., and so the system switches back to working with the old-school timetable.
