This article formulates the Collaborative Gate Allocation (CGA) problem as a novel concept to reduce aircraft gate-waiting time and to increase aircraft gate utilization. The proposed CGA concept assumes voluntary collaboration and negotiation among airlines and airport operators, enabling them to share real-time information on gate-utilization and gate-sharing. The proposed policy is especially applicable to U.S. airports, as an alternative to exclusive or preferential gate-sharing practices, at terminal buildings that accommodate a large number of smaller airlines during periods of high...

Sea level rise (SLR) will pose the greatest threat to coastal airports in the near future. Finding effective ways to mitigate or adapt to the impact of SLR is a challenge that many engineers and city planners have been addressing for a long time. The purpose of this study is to explore the potential of seaplane bases and seaplanes as future modes of transportation. Although seaplanes were most popular in the early twentieth century and were eventually phased out with new land-based aircraft, they can potentially be of great use in future climate scenarios. In this study, we propose a...

The emergence of the urban air mobility (UAM) concept promises to leverage a new generation of electrical vertical takeoff and landing (eVTOL) aircraft to provide three-dimensional and comprehensive transportation services. However, UAM does not provide door-to-door service and often requires other transportation modes to travel from origin to destination. To address this problem, study proposes the Urban Surface and Air Mobility (USaAM) concept that enables door-to-door travel, utilizing the same fly-drive vehicle for both surface and airborne transportation. The proposed USaAM concept...

The use of airport gate electrification infrastructure in the form of ground power (GP) and preconditioned air (PCA) systems can reduce energy and maintenance costs, emissions, and health risks by limiting the use of aircraft auxiliary power unit (APU) engines at the gate. However, their benefits can only be gained when they are actually being used; otherwise, pilots keep APUs on to fulfill their aircraft’s demands for electrical power and air conditioning. GP and PCA systems require a large initial infrastructure investment to increase energy efficiency, and they are installed with the...
