Chapter 26: Vehicle automation and transport system performance
It is expected that by 2050 the population living in urban areas will rise from 54 percent in 2014 to 66 percent of the world’s population, accompanied by a total population growth from 7.2 billion to 9.6 billion (United Nations – Department of Economic and Social Affairs 2014). In 2007 the 300 major cities in the world accounted for more than 50 percent of the global gross domestic product (GDP) and this figure is expected to grow to 60 percent by 2025 (McKinsey 2011). While concentration may lead to some economies of scale by making viable high-capacity public transport (PT), the reality is that large conurbations are made of different land-uses and densities which result in different trip rates and mobility patterns which hinder the sole use of PT. Moreover, mobility is becoming more diverse in time and location, resulting from greater needs for activity participation and available income for travelling.
