Departure time choice modeling: accounting for flexibility and latent effects

Presentation by Mikkel Thorhauge, PhD student, Technical University of Denmark




Abstract: The focus of this study is departure time choice modeling of car commuters in the morning rush hours. To model this we use the approach first formulated by Small (1982), i.e. the Scheduling Model. This study will contribute to the research of departure time choice modeling in three distinct ways. Firstly, by designing an efficient stated choice design specifically built to capture the trade-offs being made in the choice of departure times. Secondly, to account for detailed level of flexibility not only in relation to the specific trip under question, but for trips and activities throughout a 24 hour time period. This is important because a crucial problem when studying departure time is that the choice of when to realize a given trip is (often) related to the full daily activity pattern, such as a restriction or a preference in one activity may form restrictions in the flexibility of other activities and thereby affects the preference for the related departure time. And thirdly, to incorporate latent variables to measure underlying preferences that potentially affect departure time following the Theory of Planned Behavior, as these preferences are believed to be an important factor in explaining behavior.

Speaker Bio: Mikkel Thorhauge completed his bachelor's degree in Civil Engineering at the Technical University of Denmark from 2004-2007. Following, he graduated from the Technical University of Denmark in 2010 receiving my master's degree in Transportation and Logistics specializing in Traffic and Transport Modelling. In 2011 he started his PhD at the Technical University of Denmark with a specific focus on departure time modeling, under the supervision of Professors Jeppe Rich and Elisabetta Cherchi. In the autumn of 2013 he arrived at the UC Berkeley Institute of Transportation Studies as a Visiting Student Researcher as part of a 5 month long exchange period hosted by Professor Joan Walker.
