Bus Rapid Transit - Environmental Problems

Environmental Problems

The typical diesel engine on the bus causes noticeable levels of air pollution, noise and vibration. With hybrid vehicles and the new forms of trolleybus, BRT designers hope to increase ride quality and decrease pollution. Since the energy used for acceleration is proportional to the vehicle mass, electric traction allows lighter vehicles, faster acceleration, and ability to feed energy back into batteries or the power grid through regenerative brakes. Regenerative braking has also become standard on many modern rail systems.

A BRT system can use trolleybuses to lower gaseous and noise emissions. The price penalty of installing overhead lines could be offset by the system's environmental benefits potential for savings from centrally generated electricity, especially in cities where electricity is less expensive than other power sources. In addition, most trolleybus applications can be converted to light rail with the only extra expense being the laying and maintenance of tram tracks in the street.

Famous quotes containing the word problems:

    Hats have never at all been one of the vexing problems of my life, but, indifferent as I am, these render me speechless. I should think a well-taught and tasteful American milliner would go mad in England, and eventually hang herself with bolts of green and scarlet ribbon—the favorite colour combination in Liverpool.
    Willa Cather (1876–1947)
