But how many trips during peak, and are you able to get enough
loading for the rest of the trips to justify DDs? No, because
outside peak, it is relatively empty. What 167 and 980 needs is
firstly, a staggered arrival timing (they come together, always)
and secondly, higher frequencies using single deckers, it will be
more beneficial to passengers this way as they will have a shorter
waiting time AND more seats. Putting DDs will only give you the
latter, not the former.
But in the same vein, you can actually see a lot of empty DD's
on 190, 972 and 960 during off peak also. They dont actually need
DD's in the town-going direction after AM peak especially after the
opening of DTL in Bt Panjang. At 6pm at the junction of Steven Road
and Bt Timah Rd, town-going DD's on 190, 700, 960 and 972 are all
practically seen to be empty.
