I DeparturesA key characteristic of human movement over the past century has been the shift from rural spaces to urban places. As the twentyfi rst century unfolds, more people now live in urban environments than in rural settings, with dozens of cities housing 10 million inhabitants or more scattered across the globe. Combined with the impacts of economic and cultural globalization, the growth of urban centers has spurred transportation geographers to develop new theories and methodologies to help explain the changing dynamics of accessibility and mobility. One of the more signifi cant challenges involves rethinking the local within the context of the global, particularly in terms of how transportation supply and demand mechanisms are shaped by decisions made at myriad scales. Although transportation policies are not always made with local conditions in mind, these policies invariably have local implications.Two previous reviews in this three-part series have examined transportation research at the global and regional scales. They highlighted the signifi cant progress made by transportation geographers since the 1980s in developing theories and methodologies that provide context for movement and interaction at local scales. Although sophisticated interconnected global networks have evolved that shape and infl uence new regional mobilities, from a practical standpoint the demand for, and supply of, transportation is always grounded in the local! In this fi nal review, progress in transportation research along the urban-rural continuum at the local scale is emphasized. Urban transport issues have tended to dominate the discourse, in part because of the sheer size and complexity of urban growth and change. Yet rural accessibility and mobility challenges have also garnered significant attention from transport geographers as agricultural changes, migration, and resource depletion, among other issues, have restructured the local development matrix.
