Are cost increases of operators passed on to commuters?

Profits are necessary for all companies, including public transport operators. Profits allow the business to be sustained into the future; for investments to be made, and for service quality to be improved. Profits are what drive companies, including the operators, to be efficient and customer-focused. The PTC wants to retain the motivation for operators to continue to improve and to be efficient, because this will best serve commuters' interests in the long run. Nonetheless, the operators are not free to charge what they think the market can bear as the fare adjustment formula protects commuters by capping fare increases. In short, the fare adjustment formula has an in-built mechanism to cap fare adjustment, to ensure that public transport operators strive to do their best, and the benefits are shared with commuters.
The issue of service quality is kept separate from the fare formula. This allows the fare review mechanism to truly reflect and address the cost changes of the operators without making the fare formula too complicated.
Commuters' interest in terms of service provision will continue to be safeguarded by existing regulatory framework for bus and train services.
Concession Cardholders are required to present their Concession Cards to prove their eligibility for travel concessions, including concessionary cash fares.
The Concession Card is to be presented and placed on the fare reader. This is to verify the validity of the Concession Card before cash is deposited into the fare box.
The practice of making annual fare adjustments helps ensure that fare adjustments are aligned to economic conditions. It allows fare adjustments to be made in regular and smaller steps to moderate the impact on commuters. While public transport fares are reviewed annually, this does not mean commuters will see higher fares every year as the fare formula could yield a positive or negative quantum. In addition, any fare adjustment is subject to the PTC?s evaluation and based on the prevailing conditions at the time of the fare review exercise and guided by the fare review mechanism. If necessary, the PTC will exercise its flexibility to vary the fare adjustment when there are circumstances that justify it, such as adverse economic conditions.
