The majority of studies of air travel choice behaviour make use of Revealed Preference (RP) data, generally in the form of survey data collected from departing passengers. While the use of RP data has certain methodological advantages over the use of Stated Preference (SP) data, major issues arise because of the often low quality of the data relating to the unchosen alternatives, in terms of ex...

This research examined travel behavior of Managed Lane (ML) users to better understand the value travelers place on travel time savings and travel time reliability. We also highlight the importance of survey design techniques. These objectives were accomplished through a stated preference survey of Houston’s Katy Freeway travelers. Three stated choice experiment survey design techniques were te...

This paper evaluates the importance of factors affecting commuter bicyclists’ route choices. Both route-level (e.g., travel time) and link-level (e.g., pavement quality) factors are examined. Empirical models are estimated using data from a stated preference survey conducted by the authors over the Internet. The models indicate that, for commuter bicyclists, travel time is the most important fa...

This study evaluates individual preferences for five different cycling environments by trading off a better facility with a higher travel time against a less attractive facility at a lower travel time. The tradeoff of travel time to amenities of a particular facility informs our understanding of the value attached to different attributes such as bike-lanes, off-road trails, or side-street parki...

OBJECTIVES Examine the validity of using a self-completed Stated Preference Discrete Choice Modeling (SPDCM) questionnaire to measure parents' preferences for vaccinating their children against varicella. METHODS A qualitative approach was used to assess the way parents understood the technical information in the questionnaire and the factors they considered to be important to the immunizatio...

it is a well-known result in both environmental economics and natural resources managementthat you will not be able to manage what you are not able to measure. this paper presents a dichotomous-choicecontingent valuation survey that analyses individuals’ preferences for the implementation of a rural developmentprogram (rdp) that fosters the provision of non-commodity outputs in rural areas in s...

This paper reports the results of a stated preference experiment designed to test for how information provided in a survey affects knowledge, and how knowledge affects preferences for a public good. A novel experimental design allows us to elicit subjects’ ex ante knowledge levels about a good’s attributes, exogenously vary how much new objective information about these attributes we provide to...

This paper introduces a variant of choice experiment valuation designed to ameliorate common limitations related to a lack of ecological clarity in stated preference survey scenarios. This approach, which we call BioindicatorBased Stated Preference Valuation (BSPV), is distinguished by guidelines that inform the structure and use of ecological indicators to define policy scenarios in valuation ...
