Sustainable urban transport (SUT) systems are urgently needed in developing and emerging economies world-wide. Fast rates of motorisation, especially increases in private car ownership and travel have already turned congestion, air pollution and noise into common problems in many emerging and developing cities. Due to lost time and higher transport costs, road congestion is estimated to cost Asian economies 2-5% of GDP per year already. Asian cities also suffer from the highest air pollution levels in the world with transport being one of its largest contributors.
