This paper explores the influence of the dimensions of stated choice (SC) designs on the value of travel time savings. Utilising principles of experimental design, 16 choice designs are embedded within a global design in which we vary the number of choice sets, the number of alternatives in each choice set, the number of attributes per alternative, the number of levels of each attribute, and the range of attribute levels. A mixed logit model is estimated in which design dimensions are interacted with the attribute parameters to explore the influence of these dimensions on willingness to pay (WTP) for travel time savings. The evidence in the context of a sample of respondents in Sydney choosing amongst trip attribute bundles for their car commuting trip suggests that design dimensionality does influence variations in WTP, with higher overall mean values of travel time savings associated with more complex designs, in terms of the number of items to process.

Asymmetric preference formation in willingness to pay estimates in discrete choice models (2008, methodology): “The use of the referencing approach is made possible through the use of SP design strategies that relate the experiences of sampled respondents to the experiment (see for example, Hensher 2004a, Hensher et al. 2005; Train and Wilson 2006).”
Still Feeling the Car – The Role of Comfort in Sustaining Private Car Use (2015, background): “Popular preference for the private car is traditionally conceptualised as motivated by rational and utilitarian factors, such as the desire to save time or increase reliability (for e.g. Hensher 2004; Brownstone and Small 2005).”
Should Reference Alternatives in Pivot Design SC Surveys be Treated Differently? (2009, methodology): “Within the literature, there has been a growing trend towards the promotion of SC experiments where the attributes of the alternatives are pivoted around the knowledge base of sampled respondents (for applications see for example Hensher and Greene, 2003; Hensher, 2004).”
Estimation on stated-preference experiments constructed from revealed-preference choices (2008, background): “Applications include Hensher and Greene (2003), Hensher (2004, 2006), and Caussade et al. (2005).2 The advantage of pivoting is that it creates more realism in the sp experiments by assuring that the alternatives are similar to that which the respondent has experienced in an rp setting.”
The impact of offering two versus three alternatives in choice modelling experiments (2009, unknown): “Hensher (2004) employed mixed logit models to identify that stated choice design dimensions, including the number of alternatives, was linked to variations in willingness to pay for savings in travel time.”
Stated and inferred attribute non-attendance in a design of designs approach (2014, methodology): “, Hensher and Rose, 2009). Furthermore, both Scarpa et al. (2013) and Kragt (2013) compared two approaches, one not incorporating and one incorporating stated ANA.”
