Uncovering the influence of commuters’ perception on the reliability ratio. (working paper)

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. […]

Agglomeration, Accessibility, and Productivity: Evidence for Urbanized Areas in the US (working paper)

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 […]

Trends in Metropolitan Network Circuity (working paper)

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 […]

The Time Between: Continuously-defined accessibility functions for schedule-based transportation systems (working paper)

 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 […]

Network Structure and Travel Time Perception (working paper)

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 […]

Multi-agent Route Choice Game for Transportation Engineering (working paper)

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 […]
