COMPONENTS OF CHANGE IN URBAN TRAVEL

Home-interview travel surveys in two upstate New York areas-Buffalo and Rochester-were conducted in the early 1960s and repeated in the early 1970s. An analysis of the changes in travel and household characteristics for both areas shows some surprising patterns as well as many that support the current theories of urban growth. Travel increased 8 percent and 37 percent in Buffalo and Rochester, respectively, over an 11-year period. However, average trip rates and trip lengths remained relatively constant over time, whereas automobile-ownership levels, number of households, and average travel time increased. In general, the increase in person kilometers of travel over time resulted primarily from an increase in the number of households rather than from increasing trip rates or lengths. The theory that travel-time budgets are stable holds for travelers and, to a lesser extent, for households. New highway construction does not appear to have generated large numbers of new trips but has had a greater impact on trip origins and destinations. Analyses of various stratifications of the data showed generally similar results.
