This study explores the benefits that can accrue if cities prioritise active mobility and public transport. It quantifies the benefits of walking, cycling, and public transport in the Africa region, comparing alternate investment scenarios for the 188 largest African cities. Under a Business-as-Usual (BAU) scenario, cities would continue to focus on road expansions, flyovers, and other investments primarily catering to personal car use. In a Sustainable scenario, cities would develop adequate facilities for walking, cycling, and public transport, facilitate compact land use, and adopt measures to manage the use of private motor vehicles.
