A study of pollution and energy use by transportation has found that the automobile is not as it is frequently thought to be. The study which focused on the load factor in transportation, found that the automobile with a nationwide average of 2.2 persons has a load factor of 25 to 30 percent while on buses and electric transit, it is somewhat less. Statistical performance records, however, show that the urban bus is roughly twice as energy efficient as the typical auto. The main reason for this is that buses use high-pressure tires and are powered by efficient diesel engines. It is suggested that the energy efficiency of autos with small engines and high pressure tires would be almost equal to that of buses.
