The growing popularity of mixed logit to obtain estimates of willingness to pay (WTP) has focussed on the distribution of the random parameters and the possibility of estimating deep parameters to account for heterogeneity around the mean of the distribution. However the possibility exists to...

Travel price and time elasticities are increasingly being derived from discrete choice models of the multinomial or nested logit form. These elasticities are then applied to obtain predictions of changes in travel demand consequent on a policy change in prices and travel times. The majority of...

This paper explores the complexity and cognitive burden associated to stated choice experiments. Complexity is analysed in terms of design dimensions such as the number of available alternatives, the number of attributes used to define these alternatives, the number of levels for those...

In the stated choice literature, increasing attention has been paid to methods that seek to close the gap between the choices from these experiments and the choices experienced in the real world. Attempts to produce model estimates that are truer to real market behaviours are especially...

As urban areas face increasing demands for new transport infrastructure to promote a sustainable future with an increasing reality of constrained government budgets, the debate on whether we should focus on rail or bus-based investments continues unabated in many jurisdictions. Associated with...

Two issues that reflect how individuals make travel or vehicle purchase choices are the relevance of attribute levels associated with alternatives, and the extent to which the respondent is certain of actually choosing the alternative that they indicated was their preferred alternative. This...

A growing number of empirical studies involve the assessment of influences on a choice amongst ordered discrete alternatives. Ordered logit and probit models are well known, including extensions to accommodate random parameters and heteroscedasticity in unobserved variance. This paper extends...

This paper investigates factors likely to increase a person's risk of social exclusion, drawing on survey data specifically framed for this purpose. We use a generalised ordered logit model that accounts for observed and unobserved heterogeneity and derive the marginal effects for each...

Attitude towards risk is important to individual decision making. Rank-dependent utility theory is an appealing framework within which to study decision making under risk. This paper specifies Rank-Dependent Utility (RDU) models in the context of a stated choice experiment of commuter's risky...
