Public transport to raise fare?

When was the last fare hike? Is public transport a strategic asset, a scarce resource? If so it must be priced right to make the people feel the pain of higher transport fare so that they would not abuse taking public transport unnecessarily and wastefully. Building infrastructure for public transport is very expensive and new transportation system is not cheap, not when you need to build for another 2m people in an already congested piece of rock. All the costs have gone up. The public must be encouraged to travel at off peak hours or not to travel at all and make unnecessary trips to stress the public transport system. Do these kinds of reasoning sound right or idiotic?
 
With rising cost of public transportation and better quality of public transport, some media said service quality has declined so not sure which is right, it is only right to raise transport fare. The improvements over the years with each price hike did not seem to make the quality of service improved much. Maybe the increase is not high enough so not much improvement could be seen.
 
Would anyone think it is clever to raise transportation fee by 30% like water?  Someone must have been reading Machiavelli and the advice of Machiavelli must have gone into their heads. When making increases, make it big and painful, the public would soon forget the pain.  Don’t do it bit by bit. When giving out handouts, then do it bit by bit to milk as much good will as possible like wanting to give a 10c discount, give it in 10 times or 5 times, like 1c or 2c at a time at a time. The daft would be grateful for 5 or 10 times.
 
Are the public expecting to be slammed with another big transportation hike like the 30% water fee and comes the next GE all would be forgotten? Transportation hike got good reason, to improve quality of services. You want better services, pay more. So simple.
