your situation is stupid is not because of what i say.. your
situation is stupid because, you are assuming that the dwelling
time for DD is 100% longer than that of the bendies at bus
stops...which is incorrect at all...and further you does not take
into consideration the traffic congestion that bendies will
cause...
during am peak, whereby most student alight at Ngee Ann bus
stop, there is not much boarding activities and studenst on DD can
also alight from the front entrance as well. so why would a DD take
double the time at the bus stop?
same go for the afternoon when most student are going home (when
very little ppl alight at the ngee ann bus stop)... only one
entrance for boarding, so are you saying that the bendies will
depart after 1 1/2 mins while DD will take 3 mins for boarding?
maybe this is true for bendy, because most people on bendy dun want
to move in, so lot of ppl cant board?
what about other bus stops whereby the boarding/alighting is
only for a few ppl? are you saying that the DD will stay at the bus
stop much longer than a bendy? '
In the same respect, your explanation doesn't consider the
traffic congestion caused by a double deck acting like
a sitting duck at a bus stop.
Sure, not all stops will see bendies taking 1/2 the time, for
example, stops where one or two pax are alighting, then yes, it
will take the same time. And sure, not 100% of the time, as there
may be different passenger behaviours, but in general, if you have
a sizable crowd (more than 10), you would realise the bendies
unload way faster. And when you see busy bus stops, thats where it
drops below 50% of the time taken by a DD.
The flow is simple, and I have explained it before, there is
just one entrance on both bendies and double decks, but the double
decks have a choke point at the bottom of the staircase, where
people boarding will have to wait for people coming down from the
upper deck to alight, and only two lanes of flow to exit, of which
there is only one lane of passengers from the upper deck (even
if all 55 people want to alight at the same time, they will have to
form a line before coming down the stairs). And also, the
walk from most of the upper deck to the exit is a long one in
terms of time taken (vis a vis a bendy) and both climbing
up and down the stairs take additional time. So people
get stuck waiting for people to come down, even if they are just
going to the rear of the lower deck, and if they do want to go
upstairs, they will have to form a queue to go up, slows everything
down.
On a bendy, you just have to walk from the seats
to the doors, which are less than half the length of a 12m from the
seats, and there are four distinct lines that can be
formed and while sometimes there may be a wait at
the exits, it isn't a long wait, usually a few seconds before you
get to pass it, especially as there is a standing area opposite the
door which allows pax who've just boarded to overtake the
exiting pax.
I would recommend you to see a situation where congestion have
been caused by double decks where previously didn't exist. Go to
CCK Int during peak now, especially in the morning. Previously with
bendies only, there wasn't that much of a jam (just a short wait,
if there is any), now with the double decks there is a jam, and a
long wait when a double deck is in front of you occupying the
alighting berth even if there was no jam, and if you actually
look at how slow people are coming down the deckers at the
alighting berth, you'd see the clearer picture as to why there is a
jam. Meanwhile the bendies really take less than 1/2 the amount of
time there as compared to double decks, the bendies in this case,
literally come and go.
Same situation at the first pair of bus stops at
Bukit Panjang after BKE, double decks which just dwell at the bus
stops. While bendies just take less than half the time to unload
and load.
