The Transit Costs Project based out of NYU’s Marron Institute of Urban Management has been collecting data on mass transit projects around the world, inspired by a single question: Why are transit projects in the United States so incredibly expensive?
Today, the research initiative’s trove of data amounts to more than 900 projects in 59 countries, including more than 11,000 km of urban rail. The goal of the study was to compare costs and practices of building mass transit projects across countries, and derive findings to help public sponsors get costs under control.
