BACKGROUND Evidence for an association between transportation noise and cardiovascular disease has increased; however, few studies have examined metabolic outcomes such as diabetes or accounted for environmental coexposures such as air pollution, greenness, or walkability. OBJECTIVES Because diabetes prevalence is increasing and may be on the causal pathway between noise and cardiovascular di...

Network science, or the art of describing system structure, may be useful for the analysis and control of large, complex systems. For example, networks exhibiting scale-free structure have been found to be particularly well suited to deal with environmental uncertainty and large demand growth. Changes in the demand for air transportation are inevitable, and indeed seem to be upon us. The Nation...

This paper studies the possible integration of long-haul operations by transportation mode and service level (defined by guaranteed delivery time) for package delivery carriers. Specifically, we consider the allocation of deferred items to excess capacity on alternative modes in ways that allow all transportation modes to be utilized better. Model formulation and solution techniques are discuss...

Intelligent Transportation Systems (ITS) apply advanced technology to the nation’s transportation needs. ITS encompasses all areas of transportation, including highway, air, water, and bus and rail transit applications and technologies; both within a single system, and within integrated, intermodal systems. New technologies from such fields as information processing, electronics, control system...
