A Joint Model of Travel Information Acquisition and Response to Received Messages

This paper presents a discrete-choice model of traveler response to information. It contributes to existing approaches by describing both the acquisition and the effect on travel choices of a variety of travel information types using a single integrative and parsimonious discrete-choice model. By doing so, the model captures the notion that both types of decisions (to acquire information and to execute a travel alternative) are the result of a single underlying system of preferences and beliefs. The model was estimated on choice sequences observed in a multimodal travel simulator experiment with information provision. Estimation results show a good model fit, and parameter estimates have intuitive interpretations.
