Lot of discussion on this. Let's analyze.
85 - Those living Fernvale/Sengkang West town
965 - Those who transfer at Sengkang MRT + Punggol road
117 - Punggol West & Punggol East. Those who used to
take 85 direct, will prefer take 3/83/85 to interchange and x-over
to 117. Those living along Punggol Dr/Field can take 50/62/LRT and
transfer to 117. This is where 965 will lose its pax who used to
take 83 and cross over-head bridge to take 965 or take 3 and cross
the long bridge along TPE to take 969
103 - Those who live at HDBs along Sengkang West / Jalan Kayu +
YCK road to Yishun
-----
Another consideration is on Yishun side. Those wanting to go to
ring road/ave 1/ave 11 have now a direct service in form of 103 or
117 near its door step.
So overall, I believe 103 and 117 will get heavy loading because
of SAP + development of Sengkang West/Punggol town
85 loading will get increase in loading due to higher occupancy
in Sengkang West town offset by alternative options such as 103
(SGK West) / 117 (Punggol East).
965 is the one whose loading will get majorly affected due to
reduction in those who transfer at Punggol road, will now do with
117 at interchange + those who alight at Sengkang via MRT to take
965, can now also choose to alight at Punggol. In AM, people will
prefer 117 even more as can get seat in Punggol for MRT.
I shall show a live demonstration early next week and maybe few
months later the exact timing why sbs 85 is still trusted to be
depended upon for a guy (Riveria LRT along Punggol east to khatib
mrt) and if he takes bus to Punggol interchange to switch to sbs
117 and alight at khatib mrt too.
Maybe if he takes direct bus sbs 85, it will be about 5 min
later than 3/83/85-> sbs 117.
Starting stop: bus stop outside Riveria LRT
Ending stop: bus stop outside khatib mrt.
Choice 1: direct sbs 85 (20 stops from Riveria LRT to khatib
mrt)
Choice 2: 3/83/85 (5 stops from Riveria LRT to Punggol bus int)
transfer sbs 117 (19 stops to khatib MRT). Total 24 stops plus
waiting time for transfer.
It seems choice 2 will be faster but maybe not by too much.
People always tend to forget or discount the time you need incur
waiting when you transfer. This is why when people type, it seems
easy to think one way. However, reality is what we depend
upon.
You decide.
Cheers. Thanks.
