first point, not sure how you think it is easier for BC to ask
paxes to move in to the back end of the bendy? by
shouting?
Common sense? how do u explain those bendies which are full in
front and empty at the back...
so DD resulted in public transport not improving? So public
transport will improve when all the services are running bendies
and all the interchanges have to be expanded to accomodate with the
bendies? last time, we already argue on this matter as well...have
explained previously that bendies buses does not necessary speed up
loading at bus stops, since NOT ALL PAXES alight at one bus stop
(only at some major bus stops where there are more
alighting)...
further, 2 bendies buses can alight together, but 3 DDs can
board/alight together... so things still the same.. not so sure
about the fact that the bendies speed up traffic flow when it is
infact taking more road space?
you yourself admit Singapore is too dense a city and further it
is too small, that it cant afford 2000 bendies to be running around
the roads of Singapore... no space to park them also...
this is taken at around 830am at junction of Bishan st22/Bishan
Road.
A sv52 DD travelling towards Bishan Mrt with upper deck fully
seated and lower deck full as well...Paxes board along St22 which
is quite nearby... so since you say generally short distance dun go
upper deck, then how do u explain this? u go can see for yourself
from8am to 9am at this junction...
2 bendies vs 3 DDs can
alight assuming the same space, and this brings us to the following
example I have posted before:
Based
on the absolute space taken, the DDs win, but a stationary bus is a
sitting duck. When you take into account of the flow, you will
realise more pax can be cleared with a bendy.
Based
on observations, bendies take less than half the time of DDs
dwelling at busy bus stops, having similar and significant boarding
and alighting activities. Using simple, easy to calculate numbers,
the calculation is as follows:
In a
given 6 minutes time frame, and 36 m space. As you have said 3 DDs
OR 2 bendies can fit into the space. But lets simply assume a bendy
takes half the time (in fact, in reality, more often than not it
takes less than half) of a DD. And for simplicity sake, lets assume
a double deck takes 3 mins (at stops like NP and SIM, 5 mins is not
unheard of), and a bendy takes 1.5 mins. Ie each DD space can be
used by 2 DDs in 6 mins and each bendy space can be used by 4
bendies in 6 mins.
You
could fit 3 DDs x 2 buses per space OR 2 bendies x 4 buses per
space.
So in
a given 6 minutes time frame, you could fit 6 DDs OR 8 bendies.
The
above calculation was deliberately made simple, but it can be
extrapolated to fit different dwelling times.
The above assumes a DD
takes just 3 mins while a bendy takes 2 mins. In reality, DDs can
take 5 mins or more to complete boarding and alighting (see 74, 154
at NP/SIM or Clementi MRT). And also note that typically, a bendy
can take in a few more people than a DD in terms of total
capacity.
How about DDs where people don't move upstairs? Like DDs on 222,
291, 983 where it takes some effort for the drivers to get them
upstairs, or in the case of 291, the DD is delayed such that the
next bus (usually a Scania) is at waiting behind to enter the
berth. Do you know that before the introduction of 983, there
wasn't a need to place any staff at CCK Ave 5 (the former 300
u-turn part) to force people to move to the rear of the 300 bendy
but a few days after 983's DDs were introduced, during the morning
peak, staff have to be deployed to force people to go upstairs?
Waste of resources as the staff could be used for other things like
controlling buses at the interchange.
How sure are you that passengers can't hear a bus driver
shouting on a bendy when usually you will be able to hear the
commotion even when sitting at the last row of a bendy, maybe you
don't sit there often so you won't know.
