My 2 cents worth of analysis for Service 50:
86, 159 : Sengkang to AMK MRT will be a rapid route on Service
50. Probably will take some load off 86 and 159.
86's main demand is between sengkang to YCK MRT, as well as the
industrial companies along YCK road, if 50 brings passengers faster
to AMK MRT, demand for 86 will drop significantly. 159 as
well.
163/163M: I dont think demand for 163 will be affected alot, as
Fernvale definitely needs more bus services. And, 50 only duplicate
a small part of 163's route, main loading of 163 will not really be
affected. Serves as an important link from Sengkang to YCK
Road(industrial areas,where the highest demand lies on 163), as
well as Upper Thomson Road and TPY, hence 4-5 DDs for 163 will
still stay. As for 163M, i think it should be removed/withdrawn and
these buses to be put into 163 to improve frequency.
88/156: Sengkang/Punggol areas to Bishan. I believe 50
will take a big load of passengers from 88/156.
85/372: Anchorvale? Hmm.
I don't think it will affect loading on svc 86. There is hardly
anyone traveling AMK to Jalan Kayu. It is mostly from YCK MRT to
Jalan Kayu / YCK Road.
Also 86 from YCK to Jalan Kayu will be faster than 50 from AMK
to Jalan Kayu.
Agree. It will affect loading on 372. But then 372 did need
fleet addition.
Will not affect svc 85.
156 - how? 88 - ofcourse, will take some load - and much needed
to provide one more service than just 88.
