Purpose The Spanish airport system contains several regional airports within an amenity distance and alternative travel modes. Profitable cross-subsidise small airports, which are not required for development or connectivity. Airports government-owned centralised-managed by Air Navigation (AENA, its acronym). This study aims to analyse the probability of under-used public infrastructure AENA’s ...

A ccording to the Federal Aviation Administration (FAA), 800 million people are expected to board airplanes in 1999. In 1987, the 17 largest airports accounted for more than half of the air passenger enplanement in the United States.’ As airports get larger and more complex, passengers expect more help from curbside to aircraft seat. With extensive hotel, shopping, and recreational complexes sp...

Critical infrastructures are ubiquitous in the modern world and include electrical power systems, water, gas, and other utilities, as well as trains and transportation systems including airports. This work is concerned with Supervisory Control and Data Acquisition (SCADA) systems that are at the heart of distributed critical infrastructures within airports. Modern airports are highly competitiv...

The process of deregulating airlines in the United States began in earnest with the passage of the Airline Deregulation Act of 1978. The Act set in place a timetable for removing government controls on fares and entry into routes. However, airline access to airports has not been fully deregulated. In 1968, the Federal Aviation Administration (FAA) adopted the socalled "high-density rule" to com...

Robust face identification system in complex airport environment, which can identify certain candidates from a crowd of people in real time, is in urgent demand. S-AdaBoost is discussed in this paper as a variant of AdaBoost to handle real world environment. The Face Identification System for Airports (F1SA), based upon SAdaBoost algorithm, is implemented in an international airport. Comparison...

This paper describes a new concept for operations in non-radar “terminal” airspace around small, nontowered airports. Currently, air traffic operations in instrument meteorological conditions (IMC) at airfields without control towers and radar service are severely constrained by what is known as the “one-in/one-out” paradigm. Under these conditions only one operation (either arrival or departur...

BACKGROUND As a well-known, physical carcinogen, ambient X-ray pollution assessment would be of great importance in today's modern world. Accordingly, the present study was done to measure the exposure level of ambient X-ray at inspection gates of two airports in Iran. According to which, the X-ray was measured at different points of the inspection gates including closed and opened Curtain, as ...

We describe the use of discrete event simulation in modeling the curbside vehicular traffic at airports. The dynamic nature of vehicular traffic poses a challenge in developing a discrete event simulation model to represent roadway operations. We present our simulation methodology in modeling the new Austin-Bergstrom International Airport and address the use of simulation in the design as well ...
