This overview of transport geography explores both institutional and analytical approaches to both intra- and inter-urban transport and relates them throughout with contemporary examples. The work describes the historical development of US transportation.

Providers of transportation services may reduce their average unit costs by bundling flows and channeling them between hubs (also known as concentrators or routers). The resulting facility locations are interdependent because of the flows between them. This paper analyzes mathematical models of hub systems in an effort to enhance understanding of the optimal location of interactive facilities. The paper examines the behavior of solutions to several alternative models that require the location of a hub at either of two similar locations. A model employing a concave cost function favors the assembly of flows, penalizes fractional facility locations, and produces local minima that have integer facilities.

Archived travel data (ATD) derived from various private sources has attractive characteristics that suggest it can be a suitable replacement for traditional sample-based external travel studies or other similar origin-destination (OD) studies. The hope is that this new source of information will reduce or eliminate several negative characteristics of traditional methods. Before this hope can be realized, however, the new solution must be validated; this is the main intent of this research project.
