Draw the line on hogs who
won't move to the back of the bus
COLIN TAN WEIJIAN
It is assumed that most bus passengers know they must move to the
rear to allow others to board. However, this does not happen most
of the time, hence causing a tight squeeze at the front of the
bus.
These passengers do not move to the rear probably because of the
hassle of squeezing to get to the exit when alighting.
Besides, there is a tendency for passengers to leave huge gaps
between themselves and other standing passengers.
I have a few suggestions.
Draw lines on the bus floor, denoting boxes of space a passenger
can occupy. This way, passengers will know how much space they can
occupy when standing, without hindering the movement of other
passengers, and also to maximise the capacity of the bus. Also,
passengers will know how much they should move in when there is
empty space at the back of the bus. These boxes should be big
enough for an average person to stand in, but also not too close.
The number of boxes should correspond with the standing capacity of
the bus.
Create exit doors at the back of the bus, like most private
coaches have. Perhaps, bus companies can experiment with new buses
with back doors, so that passengers have the incentive to move to
the rear.
Bus captains should remember to ask passengers to move to the
rear when required. Or, perhaps, Singaporeans need another campaign
about moving to the rear.[/b]
He think SBST so rich like that go n draw and invite people to
calculate 
There are many reasons why people do not move in to the rear fully.
Some reason includes:
1)Rear no door
2)Not moving into the rear would mean faster travel as the bus
would seem as though pack all the way and BC who are late will have
a nice excuse to skip stop so as to reduce journey time, 1 stone
kill 2 bird 
3)Some people have the mindset that other people can move in if
they want to and they need not be the ones who move in.
