The study of respondent heterogeneity is one of the main areas of research in the field of
choice modelling. The general emphasis is on variations across respondents in relative …

An increasing number of studies are concerned with the use of alternatives to random utility
maximisation as a decision rule in choice models, with a particular emphasis on regret …

Hybrid choice models expand the standard models in discrete choice modelling by
incorporating psychological factors as latent variables. They could therefore provide further …

The area of discrete choice modelling has, over recent years, witnessed the development of
ever more flexible model structures that allow for an increasingly realistic representation of …

The Hybrid Choice Model (HCM) is a modeling framework that attempts to bridge the gap
between discrete choice models and behavioral theories by representing explicitly …

The treatment of heterogeneity across individual decision makers is one of the key topics of
research in choice modelling, as evidenced by many of the chapters in this book. While, in …

Existing models of disaggregate decision-making assume that preferences, as indicated by
taste parameters and choice sets, are characteristics of the decision-maker that are …

Mixtures of revealed preference and stated preference data are recognised by transportation
researchers as offering a richness of behavioural input to travel choice modelling that is …

We provide an in-depth theoretical discussion about the differences between individual-
specific latent constructs (representing attitudes, for example, but also other characteristics …

This paper investigates alternative methods to account for preference heterogeneity in
choice experiments. Heterogeneity can be explained by assuming its influence to impact the …
