I dont think the 12m SD 3 Door trial will be successful. The
ratio of seating passengers to standing passengers is too small.
One bad thing about bendies was that it's high capacity involves
more standing capacity than seating capcity.
3 Door DD could help improve the efficiency and layover time and
also be able to provide more seating capacity so it is kind of best
of both world. SO I think this one will succeed. Only down side is
the need to go up and come down, which may not be the best for our
aging population especially for short distance commutes. But for
trunk routes, this bus will be very good to improve passenger
flow.
Feeder best option imo will still be a mix of 18m 3door buses
and 12m 2door SD. 12m 3door DD mixed with 12m 2door SD will be next
best option.
For trunks, 12m 3door DD mixed with 12m 2door SD is good. With
more MRT connections, i believe DDs can compensate abit of capacity
to have an extra staircase to speed up layover times. Eventually
Singapore can work towards 3Door DD fleet
Sadly, they aren't working smart 
Instead of giving incentives to driver for meeting a certain
target of being on time, they extend the journey time. Which makes
driver drive slowly.
But imo, the A95 3-door DD isn't ideal yet. More waiting time is
needed for passengers going down, thanks to the extra gate. Would
prefer them trying out the ADL 3 door version though..might be
better than this A95.
