Microanalysis of urban transportation demand. Paper presented at the 52nd Annual Meeting of the Highway Research Board HRB, Washington, D.C., January 1973.

A disaggregate or micro-analytic demand model for urban travel is described. Two special features characterize the structure of the model. First, the household is taken as the basic decision unit. Second, it is proposed that the social class and the stage of the life cycle of these units are important explanatory variables.
