Dear Administrator Molitoris:
The TRB Committee for Review of the Federal Railroad Administration (FRA) Research and Development (R&D) Program held its second meeting in Pueblo and Colorado Springs, Colorado, on October 23- 24, 1998. The purpose of this meeting was to provide the committee members with a first-hand review of the FRA-sponsored research being conducted at the Transportation Technology Center (TTC)1, as well as the FRA- TTCI cooperative research projects currently under way. Because FRA has a substantial investment in TTC and continues to support the TTC research facilities, it was useful for the committee members to gain an appreciation for how these facilities are used in FRA's R&D program. A second purpose of this meeting was to review a draft report on a proposed project selection process for FRA's R&D program.
The enclosed committee roster indicates the members who attended the meeting*. Following an open session with FRA and TTCI staff, the committee met in a closed session to deliberate on the information presented and to develop this report.
On behalf of the committee, I want to thank James McQueen, Steven Ditmeyer, Claire Orth, Magdy El-Sibaie, and Steven Sill of FRA for participating in the meeting; coordinating the facilities tour and meeting presentations with TTCI staff; and providing the committee with information on FRA research under way, program updates, and plans for fiscal year 1999.
Although the committee is not contractually required to submit a letter report to FRA at this time, we wish to comment on two specific and closely related issues in response to the material FRA staff prepared for this meeting on the proposed project selection process.
The committee is pleased that the proposed process strengthens the tie to FRA's safety goals, but remains concerned that those goals have a variety of origins, including political considerations. Moreover, the committee believes there should be an analytic rationale as the foundation for the R&D program. The starting point for the development of such a rationale could be identifying the greatest sources of risk, using global risk assessment as an approach to system safety management.
Risk assessment is used as a matter of course by many other regulatory bodies including the Federal Aviation Administration, National Aeronautics and Space Administration, the Nuclear Regulatory Commission, Environmental Protection Agency, and others for both the development of safety-critical systems and as part of the process of developing regulations. It is also used by military contractors in the development of safety-critical systems for defense vehicles such as aircraft and submarines. Risk assessment is a generic term that refers to the process of analyzing a system architecture, calculating the probability of errors or failures of system components, and then assembling the component risks to determine the probability of system failure. Other terms for the same concept include risk analysis and failure modes and effects analysis. Many different methodologies and analytic tools are developed and used for undertaking risk assessments. Until recently, the railroad industry has been a notable exception in its failure to use risk assessment in the development of safety-critical systems for operations.
FRA's own research related to the development of risk assessment methodologies provides examples of how the global risk assessment approach can be used. One such example is development of an analytic procedure for risk assessment of individual corridors to estimate the safety consequences of alternative train control technologies and varying traffic levels. Another is a passenger rail risk and cost/benefit analysis to assess the value of improving the crashworthiness of passenger equipment.
Risk assessment exposes hazards that might otherwise not receive the appropriate priority in safety management or in R&D. Following an objective look at all risks in a system, three questions must be addressed:
Until the transition to a global risk assessment approach can be made, the proposed FRA process should be tested on either a group of existing projects or perhaps projects proposed for fiscal year 2000 to determine how effectively that process would allow for comparisons of projects and their relative resource allocations. However, the committee remains concerned that without a risk assessment approach, resources may not be allocated to high-priority safety issues.
Recommendation: The committee recommends that FRA take a global risk assessment approach to identifying the most serious hazards in the rail system in order to develop a strategic analytic framework for the R&D program, establish priorities relative to the seriousness of the risks involved, and map those priorities to projects that hold promise for improving safety.
The regulatory process impacts the implementation of new technology that results from research. Currently, when railroads use new technology for safety purposes, they are frequently forced to duplicate their efforts by also using old methods required by regulations (e.g., specifically required equipment inspections being used along with wayside detectors for faulty equipment). The committee concludes that implementation of new technology will be significantly facilitated by the evolution to performance-based safety standards. As stated in the committee's April 30, 1998, letter report:
The committee looks forward to continuing a constructive relationship with the FRA R&D staff and to providing advice on strategic directions and appropriate goals for the R&D program. Specifically, the committee will be happy to provide guidance on the recommended evolution of the safety regulatory process and on the anticipated benefits of better understanding risks, implementing new technology, and improving safety performance.

1FRA owns the TTC and contracts for its operation and maintenance through an operating agreement with the Transportation Technology Center, Inc. (TTCI), a subsidiary of the Association of American Railroads.
* As is standard policy for NRC committees, the members of this committee meet in a closed session at the outset of each meeting to discuss any potential or perceived conflicts of interest that might have arisen for any of them. The committee has agreed to abide by TRB policies for dealing with conflicts of interest that may arise in the bidding for or winning of FRA contracts by firms with which members are associated. In the interest of full disclosure, we note the following FRA-related activities.
First, FRA funds a research program from its Next Generation High-Speed Rail (HSR) program that TRB administers on FRA's behalf, as described below. TRB has established policies and procedures to ensure that this committee can evaluate the HSR R&D program independently of any impact its evaluation might have on TRB or the NRC. Funding is provided by FRA at a level of $1 million annually for a High-Speed Rail Innovations Deserving Exploratiory Analysis (HSR-IDEA) program that solicits innovations for technologies related to HSR safety and systems. (The $1 million provided to TRB for this program in FY 1997 represented about 3.5 percent of the HSR R&D expenditures.) The IDEA programs are administered by the Special Programs Division of TRB. IDEA investigations explore the feasibility of innovative and unproven new concepts or evaluate novel applications of advanced technologies from defense or industry to intelligent transportation systems (ITS) or HSR practice. An IDEA award is a pass-through of funds to provide one-step, short-term support.
Second, individuals with the expertise and experience necessary to review the FRA R&D program generally have some prior or ongoing relationship with the sponsor. For example, the U.S. Department of Transportation has a standing arrangement to fund research projects at the Massachusetts Institute of Technology through a Basic Ordering Agreement (BOA). In a project contracted through this BOA, Joseph Sussman and colleagues developed an analytic procedure for risk assessment, which could have application in future FRA safety regulatory analyses. A draft report for this $100,000 project was submitted to FRA in the summer of 1998 and is pending final acceptance by FRA; a contract renewal is also pending. In addition, Dr. Alan Bing's employer had two contracts with FRA in HSR vehicle crashworthiness and one in finite element analysis of crashes, with which Bing had only peripheral involvement. Bing has been leading an additional project for FRA, involving a benefit/cost analysis of crashworthiness improvements, funded for $105,000 and now close to completion. John Samuels is chairing the Positive Train Control (PTC) Management Committee for the Association of American Railroads/TTCI/FRA/Illinois DOT train control project, which is partially funded by the FRA Office of R&D and is being managed by TTCI staff with guidance from the management committee.
