Agreeing about pedestrian access making a big difference in choosing the bus. Living somewhere where I'm spoilt for choice for buses in various directions, crossing roads is often the clincher in which one I choose. I've just been to the Arnison centre and I have a choice of 9 buses an hour to get home again, not including the 50. I let a 20 go and caught the slower 64, behind it, to get home. Why? Because the 20 would have meant crossing a busy (busier than normal, today) road with no crossings to get to my house.
