Abstract: In studying transportation systems, 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 components of a system will behave, there are several drawbacks when applying these to study large-scale systems. Detailed models generally require a tremendous amount of data, involve complex numerical methods, and can lead 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 macroscopic models that only describe the behavior of individual components approximately, relying on fewer pieces of information. These models eschew detail in favor of computational simplicity and the development of meaningful insights, and are well-suited to studying large-scale transportation systems. 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 logistics and urban transportation problem.
