4.34 Discrete Choice Models Incorporating Revealed Preferences and
Psychometric Data

(formerly entitled "Incorporating Psychometric Data in Econometric
Travel Models")

This paper proposes a methodology for incorporating psychometric data
such as stated preferences and subjective ratings of service
attributes in econometric travel demand models. The first approach
combines revealed preference (RP) and stated preferenec (SP) data to
estimate discrete choice models. The second approach employee a linear
structural equation model to identify latent explanatory variables of
choice behavior. An empirical case study demonstrates the
effectiveness and practicality of the methodology.
