The broad social and economic life style changes that occurred during the past 100 years is reviewed, and the current status of the automobile as the prime means of mobility is examined. Trip distribution functions are discussed, and it is noted that the frequency of trip lengths varies with the purpose of the trip and by the sex of the driver. Vehicle occupancy is related to the degree to which the activity generating the trip involves the whole family that trips average 1.4 occupants per vehicle while educational-civic-religous and social-leisure trips average 2.5 occupants per vehicle. The paper presents and discussed the weekly time budgets for men and women in the U.S. as well as two trips of travel (work related and all other types). The amount and type of travel generated within a family is reviewed as a scheduling problem to satisfy the transport of family-based, community scale activities, a vehicle need not have high speed and long range capabilities but it must be able to carry the whole family. Regional scale work trips require a vehicle with high speed and medium range capabilities, but need only transport one or two persons. Only the regional scale family trip typified by vacation travel requires all the performance altibutes of high speed, long range and high capacity. The future of the automoible is considered from two points of view: changes in technology and ownership patterns that maintain of increase mobility, and hopefully distribute the means of mobility more evenly over the population; changes that decrease the need for mobility and our current dependence upon the automobile.
