How does PTC track fare affordability and how does it determine that fares remain affordable?

PTC ensures fare affordability by keeping a close watch over the Public Transport Affordability Indicator (PTAI), which measures the proportion of monthly household income spent on public transport for the second quintile and second decile income groups. On top of that, PTC also monitors public sentiments on affordability by gathering public feedback through public engagement sessions and surveys. PTC also monitors international comparisons on fare affordability

From 2013 to 2022, the percentage of household income spent on public transport for the average income commuter (second quintile income households) and lower-income commuters (second decile income households) has fallen from 3.1% to 2.4% and 2.2% to 1.7% respectively. The PTAI for 2023 is expected to be similar to 2022.
