reliability
Buses are notorious when it comes to schedules (hence "wait for an hour then three come along at once"). The trick they deployed is real-time arrival info.
However I am fairly dubious about it. In my city, which admittedly is a lot bigger, the busway system has the so-called real time LED indicators at each station and the buses are equipped with GPS transponders etc. but it is crap. Shows ghost buses that never arrive and so nobody looks at it or trusts it anymore. The only thing that has worked is a subset of buses/routes that are so frequent you don't think about timetables. They also require electronic card boarding, with cash not accepted.
