Differential Pricing Policy
Differential pricing is a valid means of improving profits, keeping the total cost of air transportation down, and making it possible for more people to use air transportation
Survey of projected growth and problems facing air transportation, 1975 - 1985
Results are presented of a survey conducted to determine the current opinion of people working in air transportation demand forecasting on the future of air transportation over the next ten years. In particular, the survey included questions on future demand growth, load factor, fuel prices, introduction date for the next new aircraft, the priorities of problems facing air transportation, and the probability of a substantial change in air transportation regulation. The survey participants included: airlines, manufacturers, universities, government agencies, and other organizations (financial institutions, private research companies, etc.). The results are shown for the average responses within the organization represented as well as the overall averages
Jamming transition in air transportation networks
In this work we present a model of an air transportation traffic system from
the complex network modelling viewpoint. In the network, every node corresponds
to a given airport, and two nodes are connected by means of flight routes. Each
node is weighted according to its load capacity, and links are weighted
according to the Euclidean distance that separates each pair of nodes. Local
rules describing the behavior of individual nodes in terms of the surrounding
flow have been also modelled, and a random network topology has been chosen in
a baseline approach. Numerical simulations describing the diffusion of a given
number of agents (aircraft) in this network show the onset of a jamming
transition that distinguishes an efficient regime with null amount of airport
queues and high diffusivity (free phase) and a regime where bottlenecks
suddenly take place, leading to a poor aircraft diffusion (congested phase).
Fluctuations are maximal around the congestion threshold, suggesting that the
transition is critical. We then proceed by exploring the robustness of our
results in neutral random topologies by embedding the model in heterogeneous
networks. Specifically, we make use of the European air transportation network
formed by 858 airports and 11170 flight routes connecting them, which we show
to be scale-free. The jamming transition is also observed in this case. These
results and methodologies may introduce relevant decision making procedures in
order to optimize the air transportation traffic
Virtual Integration Platforms (VIP) –A Concept for Integrated and Interdisciplinary Air Transportation Research and Assessment
The paper descibes a new methodology for a holistic development of air transportation concepts. The Virtual Integration Plattform (VIP) concept is based on an IT tool chain as well as human collaborative methods to deal with complex systems. As a result the definitions of future air transportation concepts for short range "Quiet and Clean", long range "Comfortable and Clean" and individual transport "Fast and Flexible" are presente
An analysis of short haul airline operating costs
The demand and supply characteristics of short haul air transportation systems are investigated in terms of airline operating costs. Direct, indirect, and ground handling costs are included. Supply models of short haul air transportation systems are constructed
Analysis of the Chinese provincial air transportation network
The air transportation system is of a great impact on the economy and globalization of a country. In this paper, we analyze the Chinese air transportation network (ATN) from a provincial perspective via the complex network framework, where all airports located in one province are abstracted as a single node and flights between two provinces are denoted by a link. The results show that the network exhibits small-world property, homogeneous structure and disassortative mixing. The variation of the flight flow within 24 h is investigated and an obvious tide phenomenon is found in the dynamics of Chinese provincial ATN for high output level of tertiary industry. Our work will offer a novel approach for understanding the characteristic of the Chinese air transportation network.Peer ReviewedPostprint (author's final draft
Atlanta\u27s Thriving Air Transportation Industry: Employment and Wages, 1990-2010
Air transportation is a popular form of travel in the United States and a thriving industry in the Atlanta metropolitan area, primarily Fulton County. Fulton County’s employment concentration for air transportation is higher than any other industry, and pays higher wages than the Fulton County average for all private industry. A major reason for the prominence of air transportation within Fulton County is that it houses the world’s busiest airport, Hartsfield-Jackson Atlanta International. Overall, the airport serves more than 150 domestic destinations and 80 international destinations in 52 countries, along with being the state of Georgia’s largest employer. It has been the world’s busiest passenger airport since 1998 and the world’s busiest operations airport since 2005. The local air transportation industry has faced several significant challenges over a recent 20-year period (1990–2010) including the interplay of rising fuel costs, the 9/11 attacks, and fewer passengers due to three economic recessions. These events have contributed to numerous airline bankruptcies and consolidations, which have reshaped the industry. Meanwhile, airport improvements at Hartsfield-Jackson have greatly improved efficiency.
This issue of BEYOND THE NUMBERS uses data from the Bureau of Labor Statistics Quarterly Census of Employment and Wages (QCEW) for the air transportation industry to compare employment in Fulton County, Georgia, (Hartsfield-Jackson Airport), with employment in Cook County, Illinois, (O’Hare International Airport), and Los Angeles County, California, (Los Angeles International Airport). After Fulton County, Cook and Los Angeles Counties housed the next busiest airports in the United States. This article compares total passengers and aircraft operations among the busiest airports in the United States using data from Airports Council International
