I think you read the wrong post. Better freq for 117, not 118.
This is due to the inherent nature of pax pool in the North, where
they look out for the more frequent buses to board. If 117 remain
at its current freq it isnt gonna get optimistic loading in the
North.
For 118, I was pushing for a spur seeing how majority of pax
alight to head down to Sengkang South, and it will do them good to
have a peak-period trip down without transferring.
I can understand your viewpoint, though I feel that 118 is
mainly a Punggol West - TPE stop, and TPE stop to TP/CGH/CBP
service. IIRC, that specific stop is emphatised based on the amount
of options one can transfer towards.
Sengkang/Hougang/Buangkok - 27, 88, 89, 109
Punggol East/Central - 3, 34
Yishun/Sembawang/Woodlands - 39, 168, 858, 969
If there is another pair of stops across the other side of the
flyover, one can transfer to 86 to access Sengkang West/Jln
Kayu/Seletar/YCK.
If you do wish for a spur, I have a suggestion
Punggol Rd/SK East Way/SK Int
Reason being that:
Punggol Rd to Rivervale/Upp S'goon - 86, 136
SK East Way to Anchorvale/Fernvale - 50, 372
SK Int to Hougang Ave 3/5/Upp S'goon/Kovan - 80, 87
IMO, this might work, but loading might not prove viable for LTA
to implement when current options can handle it. If pax alighting
from 118 to transfer cannot board buses towards Sengkang/Hougang,
then this might be viable as a M varient from CBP - SK
