Transportation investment policies for the 1980's will be based on the expected changes in travel demand. The magnitude of travel demand (number of trips, miles of travel), the location of demand (city, suburb, rural, northeast, south etc.) and the mode of travel (transit, auto, bicycle, etc.) depends upon population, households, household characteristics, employment location, energy supply, and the cost of travel and other factors. Economic, demographic, migration, energy use and transportation trends observed during the 1970's are identified. Projections of demographic factors and resulting transportation demands are made to the year 2000. Issues are identified which could affect DOT investment policies during the next decade. These issues include continued large population growth in areas having suburban densities, the difficulty of providing added highway capacity or efficient transit service in suburban locations, possibility of sporadic interruptions of gasoline supply, demand for housing in multi-unit structures exceeding supply and continued increases in the operating costs of public transit.
