Many US cities are failing to connect people to jobs through mass transit, according to a new report from ITDP that uses census and employment data to establish 12 new benchmarks for how mass transit systems serve urban populations. More than one third of the US cities surveyed—all with significant climate change risk—have grown without developing any substantial mass transit systems to serve their populations. The new report, Indicators for Sustainable Mobility, defines criteria to evaluate mass transportation systems and then uses the criteria to assess 20 cities in the US and compare the scores to those of eight cities in Canada and Mexico. ITDP developed a series of indicators based on three categories: proximity to transit, access to opportunity, and city characteristics. In other words: How far you live and work from a frequent or rapid transit corridor, how many jobs are available to you within a one-hour transit commute, and how densely organized the city is, allowing you to access more in shorter distances.
