Public transport makes a crucial contribution to liveable cities. Public transport provides access to employment, education, recreation and community services, as well as contributing to social equity and relieving traffic congestion. 2011 is seeing unprecedented attention given to public transport policy by our political leaders, media and the public. This reflects growing traffic and public transport congestion due to population growth and delays in overdue transport infrastructure investments. Public transport issues are also gaining greater recognition as a greener urban transport solution, as Australia faces the imperative of a shift to a lower greenhouse gas-emission economy. An international comparison of public transport mode share (based on journeys to work) shows that Australian cities have a lower share than European cities and some of the larger cities in the USA, including New York and Chicago. However, public transport has greater importance in central areas of our cities. For example, 77 per cent of people who work in Sydney’s CBD use public transport to and from work. The lower public transport mode share in Australia relates to the lower average population density of Australian cities.
