Bus Rapid Transit (BRT) is “The Green Rail” [“Cayetano vs Caldwell: Who’s the real Eco-Candidate?,” Sept. 12].

In Curitiba, Brazil, introduction of BRT reduced auto trips by about 27 million per year . . . the city now uses about 30 percent less fuel per capita (see [urbanhabitat.org])

BRT systems using low-emission buses offer the greatest reduction in CO2 emissions per passenger mile, according to a study by Breakthrough Technologies Insitute.

FTA defines BRT as a “rapid mode of transportation that can combine the quality of rail transit and the flexibility of buses.”

An FTA 2005 report concludes: “BRT is proving to be extremely effective at increasing transit ridership levels.”
