Greenhouse gases (GHG), the gases that cause climate change, are a major global concern. In the transportation sector, GHG reduction initiatives focus on passenger travel over goods movement, despite increasing freight demand and related emissions. California, with its recent GHG reduction...

In this paper, we perform a segment-level analysis of the structural differences in average gauge in the US and Europe and assess their impact on traffic and delay at major US airports. The results show that, while average gauge is consistently greater in Europe, the magnitude of the difference...

The transportation sector is one of the largest sectors contributing to Greenhouse Gas (GHG) emissions, the gases which cause anthropogenic climate change. The aviation and maritime shipping sectors are growing segments of transportation GHG emissions, yet mitigation strategies have largely...

This paper presents a comprehensive empirical analysis of flight delay impact on airfare and flight frequency in the US air transportation system. We model airfare and flight frequency as functions of cost and demand characteristics, competition effects, and flight delays at origin, destination,...

We employ ratio-based, deterministic, and stochastic frontier approaches to investigate fuel efficiency among 15 large jet operators (mainline airlines) in the US. Given the hub-and-spoke routing structure and the consequent affiliation between mainline and regional carriers, we consider not...
