Collaborative Funding to Facilitate Airport Ground Access, Research Report 11-27

This report presents the findings and conclusions from a research study that has examined the challenges of funding airport ground access projects and the role of collaborative funding strategies between the different agencies that typically become involved in such projects. The report reviews the recent literature on funding airport ground access projects, as well as funding transportation projects more generally. This is followed by a detailed review of current federal transportation funding programs relevant to airport ground access projects, as well as a discussion of state and local funding programs and potential opportunities for private-sector funding. A major component of the research described in the report consists of detailed case studies of seven selected airport ground access projects, including a major intermodal center, two automated people-mover projects, two airport access highway projects, and two airport rail links. These case studies examine the history of each project, the costs involved, and the funding programs and mechanisms used to finance the projects. Based on the literature review, the review of current funding programs, and the case study findings, the report identifies potential funding strategies for intermodal airport ground access projects, requirements for effective implementation of these strategies, and a recommended approach to facilitate successful project development and implementation. The report also presents recommended changes to transportation funding program rules and regulations that could facilitate and simplify development of intermodal solutions to future airport ground access needs

Development Of System Safety Performance Measures In Support Of The Global Analysis And Information Network

In May 1996, the Federal Aviation Administration (FAA) announced a new and innovative approach to reach the goal of "zero accidents," known as the Global Analysis and Information Network (GAIN). This is envisaged as a privately owned and operated international information infrastructure for the collection, analysis, and dissemination of aviation safety information that would involve the use of a broad variety of worldwide aviation data sources, coupled with comprehensive analytical techniques, to facilitate the identification of existing and emerging aviation safety problems. In support of this effort, the objective of the research project described in this paper is to assist the FAA in developing aviation system safety performance measures that can utilize the automated operational data that is available in the aviation system, such as digital flight recorder data and air traffic control (ATC) system data, to monitor trends in the operation of the aviation system and anticipate problems before they lead to incidents and accidents. For this to be done, it will be necessary to develop effective techniques to manage the vast amounts of data involved and appropriate analytical techniques to sort through these data and apply formal models to identify situations of interest. The goal of the current phase of the research is to review the available data sources and the techniques that have already been developed by the airlines and FAA, in order to provide the FAA Office of System Safety with a roadmap of what could be done to utilize these data sources to develop safety performance measures and what additional resources this would require. During the course of the research, discussions were held with some 25 people representing a broad range of FAA offices and industry organizations, including the FAA Office of System Safety, Office of Aviation Research, Air Traffic Service, Flight Standards Service, Office of System Capacity and the William J. Hughes Technical Center. Site visits were made to gather information on the FAA Airport Movement Area Safety System, and the NASA Aviation Performance Measuring System and Surface Movement Advisor program. Information was assembled on existing sources of operational data and data analysis tools, including those developed to support Flight Operations Quality Assurance programs. Development of the type of system safety performance measures discussed in this concept paper offers the potential to provide three useful contributions to improving aviation safety. The first is to provide a means to monitor progress toward achieving the FAA goal of reducing the fatal aviation accident rate by 80% by 2007. Since aviation accidents, particularly for commercial airline operations, are relatively rare events, it will take many years of data before any change in the underlying accident rate can be established with any confidence, much less the effect of any particular set of measures to improve the level of safety. Therefore, what are needed are performance measures that are responsive to procedural and technology changes, and measure events that occur much more frequently but reflect situations that those operating the system agree they wish to avoid, as well as conditions that aviation safety experts agree could be indicators of potentially hazardous situations. The second contribution is to provide a means for managers and supervisors to assess the effectiveness of operational changes, to identify locations or procedures that appear to generate a high number of undesired situations, and to tailor the training of flight crews and controllers to help them improve their performance. The third contribution is to provide an early warning indicator of problems that may be emerging from the introduction of new technology, new procedures, and the growth in traffic levels. For this to be achieved, it will be necessary to develop the appropriate performance measures in close collaboration with those involved in operating the system on a day-to-day basis, and to encourage a thoughtful debate on how to measure safety within the NAS and how to improve it. The operational aspects of computing appropriate performance measures are likely to be at least as difficult as deciding what to measure. Fortunately, there already exists considerable experience working with aircraft flight recorder data, and specialized analysis tools have been developed and continue to be developed, by both commercial vendors and government agencies. There is also considerable experience within the FAA and other organizations in working with radar flight track data. Experience in applying these and similar techniques to the development of system safety performance measures will determine what is useful, and whether the effort involved is justified by the results. Therefore it is proposed that a limited number of proof of concept studies should be undertaken as soon as possible to gain experience in developing appropriate analysis tools and techniques, as well as to begin involving the operating community in the process. One such study has already been proposed by researchers at NASA Ames Research Center to explore the application of concepts and techniques developed under the NASA Aviation Performance Measuring System to air traffic control system data. This has been jointly funded by the NASA Aviation Safety Program and the FAA, and is about to commence. The study would utilize the Performance Data Analysis and Reporting System, that is currently under development, to examine routine operational data in order to identify exceedances from normal operations. While the development of a comprehensive approach to measuring system safety performance needs to integrate all available information, including that derived from monitoring aircraft flight operations, as well as the operation of the ATC system, there are immediate opportunities to identify and track safety performance measures using ATC system data. Developing and implementing these measures can not only provide near-term indicators of system performance, but in the longer term can provide a consistent data stream that can be integrated into a more comprehensive framework as the other elements of this framework are implemented. It is recommended that at least two other studies be initiated addressing this aspect of the system, one focusing on terminal airspace operations and the other on airport surface operations. The first study would utilize existing tools, such as those being developed under the NASA Aviation Safety Program, to analyze radar track and system message data for a Terminal Radar Approach Control facility to identify situations that represent a departure from normal operations, including atypical controller intervention to maintain separation, unstabilized approaches, and Traffic Alert and Collision Avoidance (TCAS) alerts. The second study would explore how to effectively utilize the available sources of data on aircraft movement on the airport surface to implement safety performance measures, and would develop algorithms for extracting and analyzing data on the aircraft paths on the taxiway and runway system. The scope and level of effort of these studies could be tailored to the available resources, but it is envisaged that each of these studies would last between six months and a year, and would require between one and two person-years of effort

Aviation System Performance Measures

Within the transportation community, there is a growing recognition of the need to consider decisions addressing future investments in the transportation system from a multimodal perspective. This viewpoint has been given added weight by the passage of the Intermodal Surface Transportation Efficiency Act (ISTEA) in 1991, which not only recognized the importance of viewing the transportation system from an intermodal perspective, but also stressed the need to address the efficiency with which the system meets the transportation needs of its users. This approach was reinforced with the reauthorization of the surface transportation legislation in the 1998 Transportation Equity Act for the 21st Century (TEA-21), which added concepts of fairness in the distribution of resources to those of the efficiency of the transportation system. It is clear that to make investment decisions on a rational multimodal basis, it is necessary to be able to assess the performance of each of the modes in a consistent way, so that resources can be allocated across the modes in a way that maximizes their contribution to the overall performance of the entire transportation system. Of course, in practice existing programs and institutional arrangements have tended to remain focused on a specific mode, and thus efforts to compare performance across modes, much less to allow this to shape investment decisions, are still in their infancy. However, the California Transportation Commission has embarked on an effort to approach its capital investment decisions from such a perspective, and recent state legislation (Senate Bill 45) requires that all Regional Transportation Plans (RTPs) shall address the coordination of aviation facilities and services with other elements of the transportation system. In addition, the RTPs in any region that contains a primary air carrier airport shall include an airport ground access improvement program. As part of the current update of the California Transportation Plan (CTP), the California Department of Transportation (Caltrans) commenced work on a System Performance Measures module of the CTP, the goals of which are to develop a set of measures to assess the performance of the multi-modal transportation system so as to support informed transportation decision making, and to establish a coordinated and consistent process for performance measurement throughout the state (Caltrans, 1998c). This report addresses one aspect of that effort -- the definition of performance measures for the aviation system. This system, particularly the investment in airports, navigation aids, and air traffic management infrastructure, exists to serve its users, and indirectly to support the economic activities in which those users engage. Therefore, any attempt to measure the performance of the aviation system must consider the needs of the users and the extent to which the system satisfies those needs. From a broader perspective, the state is also interested in the extent to which the aviation system contributes to and supports the economic development of the state, as well as the adverse environmental impacts that result from aviation activities. Many of the current controversies surrounding major airport expansion or conversion proposals in the state focus not on the benefits to the users or the economy but on the impacts on the local communities or natural environment. The report examines the range of considerations that arise in measuring transportation system performance, and summarizes the results of a recent conference that addressed performance measures for the state transportation system. It reviews the recent literature on measuring aviation system performance and discusses system performance from the perspectives of the aircraft operator and traveler or shipper, respectively. It then presents a third perspective, that of the effect of the performance of the aviation system on the larger economy, particularly that of California, as well as the impact on the environment. The report then shifts its focus to the state interest in monitoring transportation system performance, and discusses the role of the state in enhancing the performance of the aviation system, and how an effective performance monitoring system can contribute to that role. Based on these considerations, the report presents a proposed set of aviation system performance measures, and discusses the steps necessary to implement an effective performance monitoring process for the state aviation system, including directions for further study to strengthen the role of performance measures in the development of the state aviation system. The report identifies 74 potential aviation system performance measures in ten categories corresponding to the system performance outcomes defined in the CTP System Performance Measures module. These are divided into 48 potential measures that address the commercial aviation sector and 26 potential measures that address the general aviation sector, as shown in Table ES-1
