Why are these options necessary?
Each of today's cars produces 60 to 80% less pollution than cars in the 1960s. However, more people are making more vehicle trips. In 1970, Americans traveled 1 trillion miles in motor vehicles, and that was projected to increase to 4 trillion miles per year by the year 2000. Transportation options are the most effective means of reducing vehicle miles traveled, congestion, and pollution.
