In this paper we propose theoretically consistent welfare measurement of use and nonuse values for an improvement in environmental quality with revealed and stated preference data. An analytical model based on the comparative static analysis of the variation function that describes the relationship between recreation demand and dichotomous choice contingent valuation models is estimated. Our re...

Waiting at ramp meters and traveling on freeways were tested using a computer administered stated preference (CASP) survey and a virtual experience stated preference (VESP) method employing a driving simulator. The selections varied in the number of minutes waiting at a ramp meter with vehicle speed once on the freeway. The subjects ranked the selections in order of preference. The results were...

Nowadays, traffic management policy in metropolitans is focused on increasing the share of public transit. The limitation of supply and slowing growth of road infrastructures have provided congestion for users who choose personal cars. Therefore, applying demand management policies which decrease the utility of personal cars and increase the tendency to public transit can be very important. Con...

The first study, “Combining Revealed Preference Data with Stated Preference Data: A Latent Class Approach”, proposes a new framework to combine revealed and stated preference data when the convergent validity assumption is not hold. While a substantial literature assume that convergence of the two elicitation approches in an “all or nothing” proposition; i.e., the RP and SP data are either cons...

Transportation researchers have recently introduced a stated-preference (sp) method in which the attributes of the sp alternatives are based on the choice that the respondent made in a real-world setting. This practice can enhance the realism of the sp task and the efficacy of preference revelation. However, the practice creates dependence between the sp attributes and unobserved factors, contr...

Over the past two decades, hundreds of stated preference studies have been conducted in less-developed countries. This article examines what has been learned on the methodological front from stated preference research, and it summarizes the empirical evidence from stated preference studies about household preferences in lessdeveloped countries. The main conclusion is that households’ willingnes...

A growing body of literature demonstrates that many behavioral anomalies observed in stated-preference elicitation methods such as the contingent valuation method are also observed in actual choices and vice versa. This presentation furthers the argument that such parallel behaviors should be viewed as a strength of stated-preference methods. Three well-known anomalies observed in both stated p...
