Hi
Would suggest MORE BUSES for all routes especially DURING THE evening peak hours AND EXTEND THE TIME TO maybe 7PM.
The service level is deteriorating significantly. Bus starting out late and commuters have to wait longer and get to work later. Also the bus gets filled up. No seats. Later along the route, some can’t even get on the bus. Why should commuters be paying premium to stand on a bus??
more and more riders are hopping on from Asia Square Shenton Way to/from Ang Mo Kio Ave 10 to/from CBD (via Outram not Orchard) so suggest more bus routes for this
The interval between first and second bus in the morning is like 5 mins. Why? I thought it should be 10 mins.
