Upon pushing back we started both engines and prepared to taxi. I cleared the left side and saw a passenger transport bus far out in the distance and looked like they had stopped to yield to us as we had our taxi light on in anticipation of taxiing. I asked the First Officer (FO) to clear the right side and he gave me the all clear as I verified it as well looking out the right side. I began moving forward to get some momentum to make the sharp left turn to taxi. As the aircraft moved forward and left I turned and saw that the passenger transport bus was starting to move slowly as well; yet far enough that he would yield to us. As we were moving further forward and now left with the tiller I was sure the driver saw our taxi light shining at them and would yield to us. It soon became apparent that the bus was not going to stop as it continued past us at a high rate of speed. My only course of action was to come to an abrupt stop. We may have been going 2-3 knots ground speed at that time. I reported the incident to ramp control informing them of the bus that had just crossed our path without yielding. The flight attendants at the time were doing the live demo in the aisle due to the MEL'd entertainment system. I called back to ask if everyone was ok and initially one of the Flight Attendants (FA) said they were ok but then paused and asked me to hold on as there might have been an injury to one of the flight attendants in the back. I was then informed that [another] FA had incurred an injury on her knee; could not continue and would need a wheelchair to get off. We called ramp and ops to pull back into [the gate] and the FA was removed from flight with a wheelchair. Replacement FA was called out and we went on our way.
