“People who use public transport are five times more physical active.”
Public Transport and Physical Activity
Using public transport increases physical activity and helps reduce the chance of obesity and other health problems related to sedentary lifestyles.
The Victorian Integrated Survey of Travel and Activity (VISTA) of 43,800 Melbournians found that people who used public transport on a given day also spent an average of 41 minutes walking or cycling as part of their travel.
This figure was 8 times greater on average than survey respondents using private transport, who recorded 8 minutes of physical activity a day.
A Perth study found commuters using public transport accumulated seven times more exercise than private motorists.
Every additional hour spent behind the wheel of a car increases a commuter’s risk of obesity by 6 per cent.

The prevalence of obesity in Australia has more than doubled in the last 20 years: 52% of women, 67% of men, and 25% of children are overweight or obese. This has significant adverse health consequences.
Environments that encourage walking, cycling and incidental exercise, such as walking to and from public transport, are considered as helping to reduce the incidence and economic costs of obesity and inactivity.
The Department of Transport in Victoria suggest default health benefit values of $A3.42/km of walking and $A1.71/km of cycling, in 2007 prices.
Public Transport and the Health System
Research has shown a significant reduction in obesity levels that comes with increases in walking, cycling and using public transport.
