Transportation corridors in megaregions present a unique challenge for planners because of the high concentration of development, complex interjurisdictional issues, and history of independent development of core urban centers. The concept of resilience, as applied to megaregions, can be used to understand better the performance of these corridors. Resiliency is the ability to recover from or adjust easily to change. Resiliency performance measures can be expanded on for application to megaregions throughout the United States. When applied to transportation corridors in megaregions and represented by performance measures such as redundancy, continuity, connectivity, and travel time reliability, the concept of resiliency captures the spatial and temporal relationships between the attributes of a corridor, a network, and neighboring facilities over time at the regional and local levels. This paper focuses on the development of performance measurements for evaluating corridor resiliency as well as a plan for implementing analysis methods at the jurisdictional level. The transportation corridor between Boston, Massachusetts, and Washington, D.C., is used as a case study to represent the applicability of these measures to megaregions throughout the country.

Sweeping changes have occurred in US cities since the 1960s. Demographic shifts have increased the population and political strength of suburbs. The economy has become globalized and many urban areas have been seriously affected by the reorganization of basic industry. Additionally, the nation is confronted with a deficit of immense proportions. This paper examines the influence of these trends on urban policy intiatives over the past four decades. US urban policy is critically explored and analyzed. The need for a national urban policy is stressed. The authors conclude that both major political parties have failed to place cities at the center of domestic policy and suggest ways to create a national urban policy.

Understanding of distributed logistics teams is invaluable to influencing the design of systems that will be used throughout the enterprise. Logistics research and development hinges on identifying the relevant variable through laboratory simulations. This paper discusses a specific laboratory task useful for examining psychological factors relevant to effective logistics collaboration in terms of both design and implementation.
