Greg Fuhs and Dario Hidalgo, active at the undisputed World Resource Institute (WRI home page) recently made a study comparing light rail and BRT system efficiency. Julia Levit of the Seatle based Worldchanging organisation made an interview with the two authors. Read the interview here.
The most prominent environmental argument is that BRT (as we previously written about) cause less CO2 emissions than the rail. This is result is based on the actual contribution of coal fired power plants to the electricity generation. Even with “green electricity” the low energy use, well to wheel, makes BRT again a winner in environmental values.
A second argument raised in the interview is the lower cost of BRT systems. By having about 50% of the investment cost more vehicles and lines can be afforded and thus a larger number of less environmentally friendly person transports can be replaced by BRT bus.
