Wah, type so long ah ? 
Service 67,176,960 can't use DDs
IMO, DDs for SBST, Bendies for SMRT. 
In Singapore, We're quite lucky to have
both Double decks and Bendies as our citybus... It will take a long
time for SMRT to switch from Bendies to DDs..
Look at 161 and 168 at WRI, DDs will take 3 to 5 minutes to be
filled during peak hours...
Most of SMRT feeders and Intratown are high-demand... Bendies is
more suitable for them, fast acceleration, fast offloading. Try
Northpoint bus stop, you can see how fast bendies on
800,804,806,811,812 unload. From full to the brim to empty bus in
less than 2 mins.
If use DDs, more worst.
I like Both Double decks and Bendies 
67 and 176 survived without DDs under SBS last time. 960 can do it
as well. Even now 67 and 960 are using more SDs to improve the
frequencies, and bendies will be useless once DTL is up.
SBS only need 3 years to build up its double decker fleet in the
late 70s and early 80s. TIBS use 3 years to familiar with bendy
buses. It doesn't need a long time to switch to higher capacity
buses, it is just how much effort that the company wants to put in
to improve the services. In our context, bendies are not practical
in our high density city and highly utilised roads and public bus
infrastructures.
So you think bendies are better in WRI??? Just look at the jams
they have created in the alighting berths. Some of the BCs have to
honk repeatedly just to tell the other bendy buses in front to
clear the jam in order for their passengers to alight. Some buses
are even stuck in the berth because of improper parking of the
bendy buses which cause the trailer part to cause jams. And not
only just the alighting berths, the boarding berths as well, long
queues of buses as well, people have to walk a long way to board
the bus or have to waste time for up till 5 mins before the front
bendy bus left so that their bus can park and let them board.
And bendies are not better in filling up during peak hours when
people don't even want to move in the other half of the bus. Many
times can take up to 5 to 8 mins, plus if another bendy bus in
front block the way, it takes up to 10 mins before the bus can
finally move.
Talking about Yishun Northpoint bus stop, it is the worst
encounter that many passengers have during morning peak, mostly
because of bendy buses. Jams, long bus queues, which cause the
whole bus stop lane to be clogged, messy and inefficient. Because
of the space that bendy buses take up, it causes a long queue of
jam all the way to Yishun 10, just because of waiting to filter
into Yishun Ave 2. Then another long jam again, and have to wait
all the bendy buses in front to clear off before your BC can open
the doors and let you alight.
There are too many services using bendy buses along that
stretch, 169, 851, 854, 856, 800, 804, 806, 812, 811, 969, which
cause too much of these jams in the limited space of that bus stop
during morning peak everyday. If SMRT use double dekers, it will be
so much better. Luckily 858 and 965 do not use bendy buses else
it will be a nightmare. Fast offloading, I seriously doubt so. I
have to waste more time instead waiting for the bus queues and jams
to clear before I can even alight my bus. Situations becomes worse
when it is raining or the 3rd bus door or EZlink card reader
malfunctions.
And it also cause many other problems for that stretch of bus
stop, where because of these long queues, some buses are stuck in
the 2nd lane because they can't filter into the bus lane, causing
jams to other road users behind. Another problem is that these bus
queues caused by bendy buses cause the services berthed in the
vertical berths in Yishun interchange to experience more jams and
waiting times to exit into Yishun Ave 2 because these bendy buses
blocked their exits to filter into Yishun Ave 2, which affects the
time travelled for passengers in these services affected, 39, 85,
852, 853, 855, 857. Some BCs have to honk at these buses to tell
them to clear off the roads. This is just a bus stop in the suburbs.
It will be much worse in the city areas.
Inside Yishun interchange, the situation is no better. Honkings
and jams and queues and parking problems caused by these bendy
buses. Even AC7 buses can't stand them. If Yishun interchange can use DDs, problems can be
solved easily.
I think you are just typing for fun without even knowing what
actually is happening daily...
