not surprising lots of people are unhappy with the presense of
UDs. I think SMRT should try to further "isolate" these buses to
the more unpopular or industrial routes instead of deploying them
on for eg 187, 980 esp.
IMO i suggest redeploying them to svc 852, 856 (to replace the
scanias), 925, scatter onto various feeder bus routes (average 1 UD
per feeder route), etc.
best is to scatter them around and avoid high concentration of UDs
on a particular route.
