DESCRIPTION:Prof. Vikash Gayah\nAbstract: In studying transportation syste
 ms\, the general trend is towards developing increasingly detailed models 
 that can describe the behavior of individual components very well. However
 \, although these detailed models might be able to predict how specific co
 mponents of a system will behave\, there are several drawbacks when applyi
 ng these to study large-scale systems. Detailed models generally require a
  tremendous amount of data\, involve complex numerical methods\, and can l
 ead to a false sense of precision due to inaccuracies in the input values.
  Furthermore\, it is often difficult to develop meaningful insights using 
 detailed models.  Instead\, it might be more beneficial to use macroscopi
 c models that only describe the behavior of individual components approxim
 ately\, relying on fewer pieces of information. These models eschew detail
  in favor of computational simplicity and the development of meaningful in
 sights\, and are well-suited to studying large-scale transportation system
 s. This talk will discuss the use of macroscopic/parsimonious models\, as 
 well as potential domains of application when compared to detailed models.
  Examples will be given of how these models can be applied to both a logis
 tics and urban transportation problem.\nBio: Vikash V. Gayah is an Assista
 nt Professor in the Department of Civil and Environmental Engineering at t
 he Pennsylvania State University. He received his Ph.D. in Civil and Envir
 onmental Engineering with an emphasis in transportation systems at the Uni
 versity of California\, Berkeley. He also received a B.Sc. (2005) and a M.
 S. (2006) in Civil and Environmental Engineering at the University of Cent
 ral Florida. His research interests are in transportation network dynamics
 \, traffic flow theory\, traffic safety and urban mobility. Dr. Gayah serv
 es as a member of the Transportation Research Board’s committee on Traff
 ic Flow Theory and Characteristics and serves as a reviewer for several to
 p transportation journals.
