Random utility maximisation is the pre-eminent behavioural theory used to model choices. An alternative paradigm, however, is random regret minimisation. While the majority of the literature examines the choices of individuals, this paper compares the choices of groups, as well as individuals,...

This paper investigates support for road pricing reform within a referendum voting choice model. Central to this is how to identify believable ex-ante support for specific road pricing schemes. Our approach is centred on a referendum voting choice model for alternative road pricing schemes, with...

There is a renewed interest in the development of behavioural models designed to identify the major determinants of household vehicle purchase. This is due, in part, to the growing interest in the economic viability of the automobile industry, rising fuel costs and increasing enhanced greenhouse...

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...

The value of fatal risk reductions is a vital input for road safety cost-benefit analysis and has been traditionally estimated by means of contingent valuation in spite of the growing criticism surrounding this approach. Furthermore, many scholars believe that risk-money trade-offs are not well...

Many econometric models exist that may be used to analyse choice data. These, however, are all based on specific assumptions made by the analyst in relation to how individual respondents make their choices. In practice, though, it may be difficult to satisfy these assumptions. Accepting that...

A major concern with the derivation of willingness to pay (WTP) distributions from mixed logit models is the incidence of values over a range that are deemed 'behaviourally questionable', with respect to the sign and magnitude. Recent research in redefining the 'space' within which a choice...

There is a growing recognition that the study of discrete choice outcomes should take into account the process rules that are used to establish eligibility of each attribute. This paper proposes a joint process-outcome model in which the choices made are conditioned on the rules adopted by each...

The value of travel time savings (VTTS) is a critical parameter in transport project appraisal and through its application produces the dominating user benefit, typically 60 per cent of traditionally quantified user benefits. Beesley's work in the 1960s laid the foundation for much of the...

Over the past two decades the bus industry in many countries has been involved in a process of economic deregulation, competitive regulation, and privatisation. Among the policy practices designed to increase competition, competitive tendering represents a popular policy intervention. The focus...
