Rapid Transit Database
Rapid transit is the backbone of public transportation, especially in large cities, because it allows people to travel quickly between different neighborhoods. It functions best as part of a larger urban mobility system that includes walking and cycling. The Rapid Transit Database (RTDB) is a collection of all rapid transit corridors worldwide that relies on data collected from government sources and publicly available news sources. The RTDB was developed by ITDP and is updated annually. View the full database here.
