But do you realize that the time between buses is same.. I have
observed at Eunos and noted towards Pasir Ris buses came as dd, Sd,
dd, Sd, dd, dd, Sd and interval was almost 10-12 mins for each bus
between 5.30 and 6.30pm at Eunos. When dd came was packed, Sd came
was packed as well... Unless it is like dd comes after 12 min and
Sd comes after 8 min of previous bus, the deployment is a little
flawed.
You can argue but I also believe for long distance routes like
Sv 21 even if there is mass DDs it do okay bcoz at different points
in route, loading exceeds 60-70 pax, and people would prefer seat
than going standing.
Nahs, I won't argue with what you observed in reality, because
that's what I had seen countless times at Paya Lebar too for Sv 21.
Just know that what I said in my earlier post was imo what was
theoretically supposed to happen.
Because if you happen to look at the e-tt, I think the freq for
that stretch is supposed to be much lesser than what you quoted
that you observed IIRC. But what the e-tt states once again is what
is theoretically supposed to happen.
But in reality, esp during PM Peak, Sv 21 gets bottle-necked
once after Kallang MRT. And that bottleneck will continue on till
somewhere along Bedok Reservoir. This happens every weekday till
like 8.30pm at Bedok Reservoir..so not surprising to see your
observations happening there..
And I think alot of people would rather take the MRT from Kallang /
Geylang / Paya Lebar areas back to Pasir Ris / Tampines during PM
Peak anyway..
