By increasing ridership on public transportation, huge amounts of fuel can be saved while also reducing the amount of air pollution.
Fuel Efficiency Single occupancy vehicles have the one of the lowest fuel efficiencies per rider of any form of transportation.  A full size diesel powered bus with as few as seven passengers offers a fuel economy greater than the average car.  A fully occupied bus has a fuel efficiency that is six-times greater while a fully occupied train car has a fuel economy 15-times greater than the average single occupancy auto.   By increasing ridership on public transportation, huge amounts of fuel can be saved while also reducing the amount of air pollution.
