Issue at interchange that the bus takes more spaces? compared to
a dd, yes, compared to 1100 single decks, not really right? It all
depends on how you view the issue, if dd is really so useful, why
didnt sbstransit acquire 700 dds instead (thats approximately
equivalent to the capacity the 1100 sd will carry)? the cost saved
and spaces at interchange saved would also be significant. In that
case, all sd will be replaced with dd, and routes can run more
sparsely, which will also save spaces taken up by sd in the
interchange!
But we very well know thats not the case and it wont be feasible
to do that. DD might be double the capacity of a sd, but consider
the other views in terms of throughput. At the interchange,
alighting at sawtooth berth, a DD can only alight with 1 door
because the stairs is exactly at the door, ppl alighting from upper
deck will block lower deck pax from alighting from front door. What
about the bendy? 3 doors at once.
Spaces at interchange such as saw tooth berths might be limited,
but if u do put a bendy on a high capacity route, there can be ways
to overcome this and even allow passengers to board more
effectively. For e.g. parking can be done at nearby depots, instead
of within the interchange, boarding can be done with 3 doors for
high capacity routes w/ assistance of ticketing inspectors at
interchange. The DD can only do 2 door at once, and as you can see
with 179A its always a bottleneck.
So back to the original point, if the feeders and intratowns
could use bendys to improve efficiency, so be it, ways should be
found to overcome the problems at int because afterall it will be
more efficient for majority of the route (all the bus stops vs just
the int)
Apologies for the wall of text.
Dun forget there's e 10 mins QoS. If we were to trade 1100 SDs
for 700 ADDs, that means bus freq would be ard 12 - 13 mins.
As for free bus spacing, it's neither true as there's not enough
spaces during mealbreaks to begin with.
For bendies, they're no where faster. You can claim they can
clear alighting faster, but wat abt their space usage? How big the
bus interchange would now be made for e boarding area? Systems is
taken as a whole, not just telling me "or, bendy faster in
alighting, so they're better".
As for 179A, obviously you've not seen how 193 & 242 make do
with the boarding. If we use bendy I think mati alrdy, lagi
inefficient. Not to mention the mess at North & South Spine, 1
by 1 strictly. Worst is e effect onto 181 & 241
especially.
As for ppl dun move upper deck, no excuse to come and claim
short distance. If you are e one along e way instead unable to
board, you will then understand. Blaming e bus co is just a blanket
to push e blame.
At e end of e day is education.
