1 trip to Yishun and here is what i've observed..
Sv860 tends to bunch up regularly, with DDs/Citaro/Bendy fleet.
At the bus stop, you can see 2x 860 arriving together, or less than
2mins. BUT, there's a big gap in between just now.
Maybe could work on deploying at a
consistent intervals rather than spamming buses...HC buses
especially.
Sv811 tends to bunch up during off peak hours. Today's trip plus
a few other days, I've seen at least 2x 811 buses bunch up, and
sometimes 3 or even more.
back to back DDs is not right when the subsequent bus coming at
30mins
859/A/B all can bunch throughout the day!
