Does the choice model method and/or the data matter?
Published 2011-07-01
The opportunity to have seven data sets associated with a stated choice experiment that are very similar in content and design is rare, and provides an opportunity to look in detail at the empirical evidence within and ...

Embedding risk attitudes in a scheduling model: Application to the study of commuting departure time
Published 2011-01-01
Traditionally, the value of travel time savings (VTTS) and the value of reliability (or reduced variability) are estimated within a linear utility functional form, which assumes risk-neutral attitudes for decision makers. ...

Accounting for differences in modelled estimates of RP, SP and RP/SP direct petrol price elasticities for car mode choice: A warning
Published 2010-09-01
Using a sample of 245 direct petrol price elasticities of car travel collected from 52 published mode choice studies, a random coefficient regression model is estimated to account for heterogeneity in the influence of the ...

Forecasting Automobile Gasoline Demand in Australia Using Machine Learning-based Regression
Published 2021
We use a variant of machine learning (ML) to forecast Australia’s automobile gasoline demand within an autoregressive and structural model. By comparing the outputs of the various model specifications, we find that training ...

Travel Decision Making Under Uncertainty and Road Traffic Behavior: The Multifold Role of Ambiguity Attitude
Published 2023-04-18
To aggregate commuters’ mode choices to traffic behavior in the presence of travel time uncertainty, we develop a dynamic traffic simulation in terms of an agent-based model, which consists of two sub-models, the mode ...

Socioeconomic Differences in Ambiguity Attitudes, Partial Ambiguity and A-insensitivity: Evidence from Real-World Decision Making under Uncertainty
Published 2019-07-01
Using a nonlinear mixed logit model, this study investigates commuter choice behaviour in the presence of uncertain travel time. Within the proposed source-dependent extended expected utility framework, the uncertainty-risk ...
