Book excerpt: A deterministic model was developed to study the effects of inefficient scheduling on flight delays at hub airports. The model bases the delay calculation on published schedule data and on user-defined airport capacities. Data from the Official Airline Guide of May, 1977 and May, 1985 was used for the analysis. Twelve large airports were studied in the hopes of finding a correlation between airport delay due to congestion and hubs. Data for both time periods was analyzed for the twelve airports in order to find historical trends in the growth of hubbing. Among the airports studied, those that were hubs had significantly more delays due to inefficient scheduling than the non-hubs, even for an equivalent number of operations. Also, these relative inefficiencies were shown to exist from hub to hub. Delays at hubs of similar size differed by up to 200 percent.
Book Synopsis Internalization of Congestion at U.S. Hub Airports by : Itai Ater
Download or read book Internalization of Congestion at U.S. Hub Airports written by Itai Ater and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: I study delays and congestion patterns in U.S. hub airports during periods of high flight volume. I find that these periods are longer when the share of flights operated by the hub airline is greater, and these longer periods exhibit shorter delays. These results lend support to recent theoretical work on congestion, implying that hub-airlines take into account the impact of their scheduling decisions on the congestion that they bear. The results may suggest that congestion management solutions implemented at hub airports dominated by one airline could have only a limited impact on congestion in general.

Book Synopsis Hub-Carrier Scheduling and Hub-Airport Congestion Pricing by : Ming Hsin Lin
Download or read book Hub-Carrier Scheduling and Hub-Airport Congestion Pricing written by Ming Hsin Lin and published by . This book was released on 2016 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examines hub-carrier scheduling and hub-airport congestion pricing using a simple hub-spoke network model incorporating both schedule delays and congestion delays. We find that in the short-middle run, where aircraft size is given exogenously, hub-airport congestion tolls are not needed at the social optimum if the (negative) congestion delay effect is more or less offset by the (positive) schedule delay effect. In the long run, where aircraft size is decided endogenously, at the social optimum, it is not necessary to impose congestion tolls via a per-flight charge or via per-passenger charges. This is in stark contrast to the results of existing literature. Interestingly, we further find that when the per-flight charge is weight related, a profit-maximizing (privatized) hub airport imposes schedule and congestion delay costs via per-flight charges, but there are no delay cost terms in the private optimal per-passenger charges. However, when the per-flight charge is movement related, it imposes schedule and congestion delay costs via both per-flight charges and per-passenger charges. These “private” optimal congestion-pricing rules provide useful insights into privatized, or profit-maximizing/emphasizing, hub airports.
Book Synopsis Evaluating the Feasibility of Reliever and Floating Hub Concepts when a Primary Airline Hub Experiences Excessive Delays by :
Download or read book Evaluating the Feasibility of Reliever and Floating Hub Concepts when a Primary Airline Hub Experiences Excessive Delays written by and published by . This book was released on 1997 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. air transportation system is dominated by a network of large hub airports. When airline schedule disruptions occur, as a result of meteorological or technical disturbances, the entire national air transportation system can be substantially delayed. This study evaluated the feasibility of using an alternate or reliever hub to connect transfer passengers who otherwise would have flights delayed or canceled as a result of disturbances at the hub airport. The study developed criteria for selecting an alternate hub and evaluated the feasibility of using an alternate hub for the Dallas-Fort Worth International Airport. This study also developed a genetic algorithm for optimizing an alternate schedule of flights into and out of the alternate hub to minimize direct operating costs and passenger delay. Based upon a case study that used the Austin Bergstrom International Airport as an alternate hub for Dallas-Fort Worth International Airport, the research concluded that it would be feasible and profitable to construct the necessary infrastructure to operate the alternate hub in Austin.

Available in PDF, EPUB and Kindle. Book excerpt: In total passenger miles, air travel has never been more popular. But as any frequent flyer knows, air travel problems are growing even faster - long lines, lost luggage, overbooking, flight delays, and serious safety issues. And instead of doing something about it, the traveling public seems simply to be sitting down, buckling in, and allowing itself to be treated like sheep.But it doesn't have to be this way. There are solutions to our air travel problems, real solutions that can make real differences. And they don't require 15 years to implement.With decades of experience in civil aviation and policy, Drs. George Donohue and Russell Shaver are well qualified to assess the problems in the system and offer responsible, workable solutions. Dr. Donohue, the current Director of the Center for Air Transportation Systems Research and a Professor of Systems Engineering at George Mason University (GMU), has extensive high-level experience at the Federal Aviation Administration and the Defense Advanced Research Projects Agency (DARPA). Dr.Shaver, formerly a senior RAND Corporation research analyst and now a visiting research fellow at GMU, served as chief scientist for policy analysis at the MITRE Center for Advanced Aviation System Development.The stories they tell are compelling. There are high-profile horror stories - passengers stranded for hours on the tarmac, flights cancelled for 'bad weather' when there's not a drop of rain anywhere near the flight path - as well as an overall sense of apathy and obstructionism among those responsible for managing the industry. Interestingly, these problems are not the inevitable result of the size or complexity of the U.S. system. Air transportation in Europe, with almost identical air traffic control systems and safety standards, is far better.Amsterdam moves 30 per cent more passengers than Newark, but the average flight delay is an order of magnitude lower. In addition, a European Passenger's Bill of Rights - giving distressed passengers the right to substantial and immediate compensation - has been a powerful incentive for non-U.S. airlines to maintain their schedules.So just how did we get where we are in the U.S. system today?Donohue and Shaver cite multiple reasons that have combined to create the chaos we now face. These causes include airline deregulation, multiple governmental agencies with no central oversight or responsibility, multiple corporate entities with conflicting agendas, and a technologically outdated air traffic control system. Even more importantly, there seems to be a complete absence of advocacy for the customer - the passengers. The authors also explain that our air travel problems, if left unaddressed, are on a direct course to greatly impact the overall U.S. economy and harm our global competitiveness. In 2006 alone, delays and cancellations cost U.S. travelers an estimated $3.2 billion. And in 2004 and 2005, the U.S. tourism industry is estimated to have lost $98 billion in revenue due to our air travel mess.Fortunately, Donohue and Shaver don't leave us in this state of chaos. Their provocative analysis not only identifies the causes and extent of the problems, but also provides us with a course heading to put us on the path to recovery.The solutions they propose include holding the government decision-makers responsible, expanding the capacity of airports and airplanes, modernizing the air traffic control system, and implementing what the authors call the '30 per cent solution' to significantly reduce congestion.In short, this book should be read by every airline passenger traveling in or through the United States. As a country, we simply can't afford to let the chaos continue.
Book Synopsis Network Effects, Congestion Externalities, and Air Traffic Delays by : Christopher J. Mayer
Download or read book Network Effects, Congestion Externalities, and Air Traffic Delays written by Christopher J. Mayer and published by . This book was released on 2002 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: "We examine two factors that might explain the extent of air traffic delays in the United States: network benefits due to hubbing and congestion externalities. Airline hubs enable passengers to cross-connect to many destinations, thus creating network benefits that increase in the number of markets served from the hub. Delays are the equilibrium outcome of a hub airline equating high marginal benefits from hubbing with the marginal cost of delays. Congestion externalities are created when airlines do not consider that adding flights may lead to increased delays for other air carriers. In this case, delays represent a market failure. Using data on all domestic flights by major US carriers from 1988-2000, we find that delays are increasing in hubbing activity at an airport and decreasing in market concentration but the hubbing effect dominates empirically. In addition, most delays due to hubbing actually accrue to the hub carrier, primarily because the hub carrier clusters its flights in short spans of time in order to maximize passenger interconnections. Non hub flights at hub airports operate with minimal additional travel time by avoiding the congested peak connecting times of the hub carrier. These results suggest that an optimal congestion tax would have a relatively small impact on air traffic delays since hub carriers already internalize most of the costs of hubbing and a tax that did not take the network benefits of hubbing into account could reduce social welfare"--National Bureau of Economic Research web site.

Download or read book Transportation written by U S Government Accountability Office (G and published by BiblioGov. This book was released on 2013-06 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1977, aircraft delays caused U.S. airlines to use an additional 700 million gallons of fuel which is over 8 percent of their total consumption, detained travelers 600 million hours, and cost the airlines over $800 million. The delays can be reduced if runway capacity at major airports is used more efficiently by shifting air traffic from peak to off-peak periods or to other airports. Another way to reduce delays is to charge peak operating fees instead of the existing landing fees which are based on aircraft weight. Quotas have succeeded in reducing delays by limitng the number of aircraft operations during congested periods. Under the Airport Development Aid Program (ADAP), reliever airports would be established to relieve congestion at major airports.
