Projecting automobile availability by urbanized area. Paper presented at the 48th Annual Meeting of Highway Research Board HRB, Washington, D.C., January 1969.

The author discusses the need for quick, inexpensive tools with which to determine future transportation requirements in urbanized areas by determining and measuring relations between a prime indicator or transport need, automobile availability, and certain socioeconomic variables. Theoretical relationships between change in automobile availability and change in certain population, employment, and income factors were formulated.
