Thresholds and indifference in stated choice surveys
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
One typical aim of choice experiment designs is utility balance, that is, the alternatives defined within each choice set should have similar choice probabilities; otherwise, choice is too easy and little information about ...
Mixed modelling of interurban trips by coach and train
(PERGAMON-ELSEVIER SCIENCE LTD, 1998)
A stated preference (SP) experiment for interurban trips by coach or train was designed and programmed on portable computers with the aid of specialized software. Trip characteristics and socio-economic information about ...
A semi-compensatory discrete choice model with explicit attribute thresholds of perception
(PERGAMON-ELSEVIER SCIENCE LTD, 2005)
Random utility models are typically based on the assumptions that individuals exhibit compensatory behaviour and that their choice sets are pre-specified. These assumptions may be unrealistic in many practical cases; in ...
When choosing might mean losing: A mixed method study of secondary school choice in the Republic of Trinidad and Tobago
(School of Education, UWI, St. Augustine, 2009)
This article argues that Trinidad and Tobago has historically operated a system of open enrolment. Open access to schools by families may be rooted in the conflict between Church and State over schooling. The system is ...
Estimating the willingness to pay and value of risk reduction for car occupants in the road environment
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
In recent years there has been a re-focus on the valuation of a statistical life from the ex post or human capital method to an ex ante willingness to pay (WTP) approach. This is in part a recognition that we may have been ...
A discrete choice model incorporating thresholds for perception in attribute values
(PERGAMON-ELSEVIER SCIENCE LTD, 2006)
In this paper we formulate a discrete choice model that incorporates thresholds in the perception of changes in attribute values. The model considers multiple options and allows for changes in several attributes. We postulate ...
Consistency of side choice in the milking parlour by holstein-friesian cows and its relationship with their reactivity and milk yield
(2001-02-19)
Dairy cows often have to choose which of two sides to enter in the milking parlour. Some cows are very consistent in this choicė, and it is common to assume that when these cows are more disturbed are being milked in their ...
Confidence intervals to bound the value of time
(PERGAMON-ELSEVIER SCIENCE LTD, 2001)
The derivation of a subjective value of time (SVT) requires finding the marginal rate of substitution between travel time and cost in a travel choice model. In the typical case of models with linear-in-parameters utility ...
Modelling the demand for medium distance air travel with the mixed data estimation method
(ELSEVIER SCI LTD, 2008)
A stated preference experiment is developed looking at airplane and a fictitious high-speed train trips between Santiago and Concepcion in Chile. Four variables are used - travel time, fare, comfort, and service delay; a ...
Modeling the decoy effect with context-RUM Models: Diagrammatic analysis and empirical evidence from route choice SP and mode choice RP case studies
(2016)
Evidence outside transportation has suggested that the introduction of a decoy to the choice-set could increase the share of other alternatives. This evidence breaks the regularity assumption, which is at the root of the ...
