Modeling Interdependencies between Vehicle Transaction, Residential Relocation and Job Change

This paper introduces a new joint vehicle transaction timing model in which household residential and job relocation timings are also incorporated. Furthermore, the household members’ job relocation timing decision along with the influence of their decisions on each others’ and also on the household residential relocation timing decision is modeled. In addition, the household residential relocation timing decision and its effect on the household members’ job relocation decision is also studied. Some researchers have modeled the household vehicle ownership decision jointly with some other household decisions like vehicle type choice or vehicle miles traveled (VMT); however, these models were basically static and changes in household taste over time has been ignored in nearly all of these models. This paper presents a dynamic joint model in which the effect of land-use, economy and disaggregate travel activity attributes on three major interdependent household decisions are examined. A hazard-based simultaneous system of equations for work and residential relocation timing and vehicle transaction timing is formulated with two baseline hazard functions of Weibull and log-logistic. In order to estimate parameters of the simultaneous system of equations, the last three waves of the Puget Sound Panel Survey data and land-use, transportation, and built environment variables from the Seattle Metropolitan Area are utilized.
