- To develop a framework for assessing the sustainability of urban public transport systems in cities
- To benchmark selected cities using the framework to assess their relative performance and areas for improvement
- To explore relationships between public transport sustainability, land use and regulatory structures for public transport.
- Development of framework containing 15 indicators covering four sustainability dimensions: environmental, social, economic and system effectiveness
- Benchmarking of public transport sustainability in 97 world cities
- Correlation analysis of public transport sustainability with land use indicators and regulatory structures operating in each city.
Prague, Dakar and Tokyo have the highest levels of public transport sustainability.
- At a world region level, Eastern Europe, Asia and Latin America achieve the highest levels of public transport sustainability (in that order); Western Europe, North America and Oceania have better performance on environmental and social sustainability but poorer performance on other aspects
- At a city level, Prague (Czech Republic), Dakar (Senegal) and Tokyo (Japan) have the highest levels of public transport sustainability, while Dubai (United Arab Emirates), Shizuoka (Japan) and Denver (United States) have the lowest performance
- Population and job density are positively correlated with public transport sustainability; about a third of overall public transport sustainability performance in cities is explained by land use
- Cities with publicly operated systems perform worse in terms of economic sustainability but better in terms of social sustainability; the converse is found for privately operated systems.
