I disagree with this as it will only complicate the route of
123.also, the green and white plate concept is only suitable
for feeder services as its distances are relatively shorter and it
only plies a town. Using this concept on trunk seRvices with
certain distances will only comfused commuters.
However I do agree that 64 have a terrible frequency as I have
encountered frequencies like 35 minutes several times
I think it anyway confuses a lot of people at Tiong Bahru Plaza who
are not regular residents. They see Bukit Merah on the
display and think it will take them to Bukit Merah but instead
it takes them to Bukit Purmei. It is odd in the first place to have
the looping so close to the terminal point.
But you are right the white/green will again be complicated.
Rather the bus can terminate at Harborfront Interchange, and can be
an alternate substitute at Bukit Purmei for 131. People will also
save coz of distance-fare.
Once the buses terminate at Harbourfront, at least the frequency
will be better monitored.
