Need as a criterion for transportation planning. Paper presented at the 52nd Annual Meeting of the Highway Research Board, Washington, D.C., January 1973.

Various methods of computing transportation needs are analyzed. The use of need is discussed in the context of multi-systems planning and other disciplines. An in-depth case study of the transportation needs of poverty groups in rural areas is discussed to illustrate methods of arriving at quantitative need estimates. Using travel behaviour data, the number of trips required for persons in several areas of rural poverty are calculated to meet the average U.S. travel standard.
