DISAGGREGATE DEMAND MODEL FOR NONWORK TRAVEL

Daily nonwork travel by urban households frequently involves visits to several destinations during a single roundtrip from home or several round trips. This paper describes a disaggregate approach to modeling the demand for nonwork travel, including multidestination travel. The approach is presented in two parts. First, a theoretical framework for modeling the demand for nonwork travel is developed that uses tours (i.e., round trips from home) and sojourns (i.e., visits to nonwork destinations) as the basic units of travel, and relates tour frequency, sojourn frequency, and destination choice to household characteristics, destination characteristics, and transportation level of service. An empirical model of nonwork travel demand that is based upon the theoretical framework is then presented. The empirical model enables tour and sojourn frequencies, destination choice, and nonwork vehicle-kilometers traveled to be computed as functions of household characteristics, destination characteristics, and transportation level of service. Several tests of the validity of the empirical model are described. The model was found to perform well. /Author/
