A method is presented for estimating the latent demand for travel by the elderly, the young and the low-income in urban and rural areas. A form of "gap analysis" is used to compare daily trip rates of individuals in auto-owning families with rates of individuals in autoless families. These comparisons are made for work, shop, social-reaction, personal business, and eat-meal trips for individuals with similar age and income characteristics. Results based on the Rochester Home Interview Survey (1963) suggest that the autoless elderly, young, and low-income urban residents differ markedly in the purpose and frequency of their trips, latent demand, and transit dependence. The elderly, and youth populations make approximately .3 non-home trips per person per day (t/p/d) whereas the low-income labor market population make .5 trips per person per day. For low-income residents, the most frequent trip purpose (.4 t/p/d) is personal business; the elderly and the young, however, make trips most frequently (.1 and .2 t/p/d respectively) for social recreational purposes. If a car were available, the elderly would make the most additional trips for shopping purposes (.3 t/p/d), the young for social-recreational purposes (.1 t/p/d) and the low-income for work purposes (.1 t/p/d). In some instances, latent travel demand can not be satisfied solely as a result of improved or increased transportation service. Therefore, interpretation of latent demand analysis results considers a number of possible influencing factors.
