Think about it..
If BC got a rule.. if got ppl standing on steps, the bus MUST NOT
move. As a customer, will u, as a customer, be more
satisfied?
If the bus stop is packed, and got buses at 3 min frequency, first
bus come (2nd bus not in sight yet), will the bus be boarded till
overcrowded? That will be the case till the 2nd bus is in sight..
3min later. Thus.. even if frequency is high, buses will still get
packed.
I think the bese solution is similar to US practices. Draw a line
near the ticket printing machine. When bus is stationary, no
standing beyond that line.. (bus no move.) Over time, ppl will not
board the bus when see ppl stand on that line.
Agree?
