The availability of panel data and the continued development of activity-based travel demand models has cast a very promising light on the prospect of significantly improving our understanding of travel demand and our ability to forecast it. A lingering concern, however, relates to the econometric structure of activity-based models given the availability of panel data. This chapter presents a number of econometric alternatives that can be used to model individuals’ activity duration (e.g. time spent shopping, participating in recreational activities, etc.). Using panel data from the Puget Sound Region in Washington State, we estimate a number of econometric models and focus on potential specification errors and predictive capabilities. The primary econometric focus is on estimating survival models of activity duration using the fully-parametric Weibull proportional hazards with Gamma heterogeneity. The estimation concerns deal with the effects of state dependence and heterogeneity and the determination of true state dependence.
