Urban areas, home to more than half of the world’s population, face unprecedented transport and mobility challenges. With rapid population and economic growth, demands for urban mobility are steadily rising. Globally, some 8 billion trips are made every day in cities of which nearly half (47%) are by private motorized modes, almost all of which are propelled by fossil fuels (Pourbaix, 2011). In 2050, there may be 3 to 4 times as many passenger-kilometers travelled as half a century earlier, infrastructure and energy prices permitting (International Transportation Forum, 2011).
