Reducing Emissions through Monitoring and Predictive Modeling of Gate Operations of Idle Aircraft: A Case Study on San Francisco International Airport

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...

The California Aviation System: Current Status and Recent Trends

Hansen, Mark M.
Gosling, Geoffrey D.
Kettunen, Tarja
Wilkins, Erik
2002

This report presents statistical information on passenger and cargo traffic, aircraft activity and delays at California airports. Five main topics are considered: passenger enplanements, air travel origin and destination (O-D) patterns, air cargo activity, aircraft operations, and airport delays. In most cases, we present data for the state as a whole, major regions within the state, and major airports within each region. Most of the data are compiled on an annual basis for the years from 1980 to 2000. The report concludes with a discussion of the changes in activity in the California...

Reversibility of the Time-Dependent Shortest Path Problem

Daganzo, Carlos F.
1998

Time-dependent shortest path problems arise in a variety of applications; e.g., dynamic traffic assignment (DTA), network control, automobile driver guidance, ship routing and airplane dispatching. In the majority of cases one seeks the cheapest (least generalized cost) or quickest route between an origin and a destination for a given time of departure. This is the "forward" shortest path problem. In some applications, however, e.g., when dispatching airplanes from airports and in DTA versions of the "morning commute problem", one seeks the cheapest or quickest routes for a given arrival...

Historical Transportation Development

Garrison, William L.
2003

The main tasks for this overview of transportation development are the provision and interpretation of information on the unfolding of the transportation systems. What have been the processes at work? What explains the similarities and differences from here to there and among systems? Big questions! But they are eased by ways systems are products of experiences, as will be seen when the paragraphs immediately following summarize early experiences. Life support systems, sustainability, and social development topics will be mentioned. After examining their immediate precursors, the...

Assessing URET Benefits for Airspace Users: A Quasi-Experimental Approach

Bolic, Tatjana
Hansen, Mark
2002

Air traffic control organizations around the world are trying to develop automation tools to help controllers manage increasing workload and to enable user preferred routes. This paper focuses on such a tool: User Request Evaluation Tool (URET), which is a decision-support tool for en-route controllers. URET is a prototype of an automated conflict probe. Based on flight plans and actual radar tracks, the URET system models aircraft trajectories and predicts possible conflicts. It also enables controllers to check clearances for conflicts prior to their issuance. This tool is intended as a...

Influence of Capacity Constraints on Airline Fleet Mix

Hansen, Mark M.
Gosling, Geoffrey D.
Margulici, Jean-David
Wei, Wen-Bin
2001

This report documents the findings of research sponsored by the Los Angeles World Airports to examine the influence of airport capacity constraints on airline fleet mix and to explore the potential effects of policy options to influence airlines to use larger aircraft types and thereby accommodate growth in passenger or cargo demand without a corresponding increase in the number of aircraft operations. This issue is of growing importance at many major airports in the United States and indeed around the world, as a steadily increasing demand for air transportation has resulted in volumes of...

The Development Of An Accident Database To Structure Land Use Regulations In Airport Runway Approach Zones Part II

Cooper, Douglas L.
Chira-chavala, T.
1998

This report presents and describes the expanded database containing 873 aviation accidents which occurred within five miles of an airport. Section 2 contains a description of the development of the database and a discussion of the criteria used in selecting accidents for the database. Section 3 provides a description of the database itself as well as a set of statistics that provide a comprehensive overview of the accidents. A set of aircraft accident scatter plots developed from the accident data points is presented in section 4. The purpose of these plots is to provide a picture of the...

The Role of Intelligent Transportation Systems (ITS) in Intermodal Air Cargo Operations

Tsao, H.-S. Jacob
Rizwan, Asim
2001

This study examines the extent to which states have devolved one of the most fundamental decisions in transportation policy—whether to use taxation powers to fund transportation improvements—to local and regional governments. The purpose of the study is to generate a baseline of knowledge on “local option transportation taxes” in all fifty states, including the relevant legislative authority for these taxes, the extent to which local areas have adopted them, and the roles they play within their states’ overall transportation finance frameworks.

Multivariate Analysis of the Impacts of NAS Investments: A Case Study of a Major Capacity Expansion at Dallas-Fort Worth Airport

Hansen, Mark M.
Wei, Wenbin
1998

This paper presents a case study of how to empirically estimate the impact of a NAS investment on system performance. We employ multivariate statistical analysis to estimate the impacts of a major capacity expansion at DFW airport.
