Best Practices ITDP Part 2Large cities of the world require strong coverage of rapid transit networks to ensure they remain competitive, and that local communities have a healthy environment, vibrant urban economy, and an equitable, high quality of life for all residents. Many cities—especially those with growing populations, incomes, and/or large infrastructure deficits—have not, however, built rapid transit at the scale and rate needed to meet mobility needs. This paper is Part 2 in a series of research papers that explores how countries can grow their rapid transit infrastructure. This Part focuses on the role that funding, financing, and capacity have played in delivering rapid transit infrastructure in nine countries.
