SINGAPORE - To avoid large swings in fares for passengers who take the bus and train, the way that yearly adjustments to public transport fares are calculated for the next five years has been changed.
Announcing the new fare adjustment formula on Tuesday, the Public Transport Council (PTC) said passenger demand has been taken out of the equation, given the continued uncertainty over the pace and extent of the recovery in public transport ridership post-Covid-19.
Changes to the formula aside, bus and train fares are set to rise in 2023, with the exact amount to be determined during the next fare review in the second half of the year. This is largely due to a 10.6 per cent fare hike that was rolled over from the previous fare review in 2022.
