Abstract

This study formulates an Integrated Choice and Latent Variable (ICLV) modelling framework that allows simultaneous estimation of route-level travel time variability and incorporation of its influence on route choice of travelers. The framework considers travel time on a route as a latent variable and uses GPS data measurements of the same to identify the parameters of its statistical distribution, while recognizing measurement errors. Notably, the framework helps inform/impute the travel time distribution for routes without measurements. The proposed model is applied to an empirical data set on route choice of freight trucks in Florida. The route choice component of the proposed model demonstrates a superior statistical fit and better predictive ability than route choice models that do not consider the influence of travel time variability on route choice.
