A SIMULTANEOUS MODEL OF HOUSEHOLD ACTIVITY PARTICIPATION AND TRIP CHAIN GENERATION

This paper describes a trip generation model developed using a time-use perspective in which trips are generated in conjunction with out-of-home activities and time spent traveling is a separate component of overall time use. The model forecasts 3 sets of endogenous variables--1) activity participation, 2) travel time, and 3) trip generation--as a function of household characteristics and accessibility indices. It is estimated with data from the Portland, Oregon 1994 Activity and Travel Survey. Results show that the basic model fits well and all postulated relationships are upheld. Tests show that the basic model, which divides activities into work and nonwork, can be extended to a 3-way breakdown of subsistence, discretionary, and obligatory activities. The model can also capture the effects of in-home work on trip chaining and activity participation. The model is used to explore the effects on time use and trip chaining of GIS-based and zone-based accessibility indices.
