Working Papers and Conference Papers, by year of release or of first public presentation, when not on Published Articles. New Li, Manman, Cui, Mengying, and Levinson, D. (2020) Job and worker density over time Wu, Hao and Levinson, D. (2020) Measuring Access by Taxi 2020 Lahoorpoor, Bahman and Levinson, D. (2020) Trains, trams, and terraces: population […]
Carlos Carrion and David Levinson (2012) Uncovering the influence of commuters’ perception on the reliability ratio. (Working paper) The dominant method for measuring values of travel time savings (VOT), and values of travel time reliability (VOR) is discrete choice modeling. Generally, the data sources for these models are: stated choice experiments, and revealed preference observations. […]
Daniel Graham, Patricia Melo, and David Levinson (2012) Agglomeration, Accessibility, and Productivity: Evidence for Urbanized Areas in the US. (Working paper) This paper undertakes an empirical analysis with the aim of improving the current understanding of the relationship between labor productivity and urban agglomeration economies across a sample of urbanized areas in the US. Agglomeration […]
Pavithra Parthasarathi and David Levinson (2012) Network structure and the journey to work: An intra-metropolitan analysis. (Working Paper) This paper aims to look at the variation of network structure within a metropolitan area and relate it to observed travel, measured here as the average travel time to work. The Minor Civil Divisions (MCD) within the […]
David J. Giacomin, Luke S. James, and David M. Levinson (2012) Trends in Metropolitan Network Circuity. (Working Paper) Because people seek to minimize their time and travel distance (or cost) when commuting, the circuity–the ratio of network distance traveled to the Euclidean distance between two points–plays an intricate role in the metropolitan economy. This paper […]
Michael Iacono, David Levinson, Ahmed El-Geneidy, and Rania Wasfi (2012) Markov Chain Model of Land Use Change in the Twin Cities. (Working Paper) The set of models available to predict land use change in urban regions has become increasingly complex in recent years. Despite their complexity, the predictive power of these models remains relatively weak. […]
Carlos Carrion and David Levinson (2012) Route choice dynamics after a link restoration. (Working Paper) Carrion and Levinson (2012) studied the bridge choice behavior of commuters before and after a new bridge opened to the public. This bridge replaced the previously collapsed I-35W bridge in the metro area of Minneapolis-St. Paul. The original I-35W bridge […]
 Paul Anderson, Andrew Owen, and David Levinson (2012) The Time Between: Continuously-defined accessibility functions for schedule-based transportation systems. (Working paper) Accessibility is traditionally considered to be a property of a point or region in space, and to be invariant over time (or at least over some computationally convenient time interval). How- ever, a locations […]
Pavithra Parthasarathi, David Levinson, and Hartwig Hochmair (2012) Network Structure and Travel Time Perception. (Working Paper, Presented at the 2012 International Association of Travel Behavior Research Conference in Toronto) Road networks have an underlying structure. This structure is defined by the layout, arrangement and the connectivity of the individual network elements, the road segments and […]
Xuan Di, Henry Liu, and David Levinson. (2012) Multi-agent Route Choice Game for Transportation Engineering. (Working paper) In undergraduate transportation engineering courses, traffic assignment is a difficult concept for both instructors to teach and for students to learn, because it involves many mathematical derivations and computations. We have designed a multiplayer game to engage students […]
