Concerns about the weak economy, congestion in the transportation system, and the potentially harmful effects of air emissions generated by the transportation sector have raised awareness of the potential benefits and costs of intercity passenger and freight rail relative to other transportation modes such as highways. GAO was asked to review (1) the extent to which transportation policy tools that provide incentives to shift passenger and freight traffic to rail may generate emissions, congestion, and economic development benefits and (2) how project benefits and costs are assessed for investment in intercity passenger and freight rail and how the strengths and limitations of these assessments impact federal decision making. GAO reviewed studies; interviewed federal, state, local, and other stakeholders regarding methods to assess benefit and cost information; assessed information on project benefits and costs included in rail grant applications; and conducted case studies of selected policies and programs in the United Kingdom and Germany to learn more about their policies designed to provide incentives to shift traffic to rail.

Although implementing policies designed to shift traffic to rail from other modes may generate benefits, and selected European countries' experiences suggest that some benefits can be achieved through these types of policies; many factors will affect whether traffic shifts. The extent to which rail can generate sufficient demand to draw traffic from other modes to achieve the desired level of net benefits will depend on numerous factors. Some passenger or freight traffic may not be substitutable or practical to move by a different mode. For example, certain freight shipments may be time-sensitive and thus cannot go by rail. Another key factor will be the extent to which sufficient capacity exists or is being planned to accommodate shifts in traffic from other modes. How transport markets respond to a given policy--such as one that changes the relative price of road transport--will also affect the level of benefits generated by that policy. Experiences in selected countries suggest that varying amounts of mode shift and some benefits were attained where decision makers implemented policies to move traffic from other modes to rail. For example, a road freight pricing policy in Germany resulted in environmental and efficiency improvements, and freight rail grants in the United Kingdom led to congestion relief at the country's largest port. Pursuing policies to encourage traffic to shift to rail is one potential way to generate benefits, and other policies may be implemented to generate specific benefits at a lower cost. Information on the benefits and costs of intercity passenger and freight rail is assessed to varying degrees by those seeking federal funding for investment in rail projects; however, data limitations and other factors reduce the usefulness of such assessments for federal decision makers. Applicants to two discretionary federal grant programs--the Transportation Investment Generating Economic Recovery program and the High-Speed Intercity Passenger Rail program--provided assessments of potential project benefits and costs that were generally not comprehensive. For instance, applications varied widely in the extent to which they quantified and monetized some categories of benefits. In addition, GAO's assessment of selected applications found that most applicants did not provide key information recommended in federal guidance for such assessments, including information related to uncertainty in projections, data limitations, or the assumptions underlying their models. Applicants, industry experts, and Department of Transportation (DOT) officials GAO spoke with reported that many challenges impacted their ability to produce useful assessments of project benefits and costs, including: short time frames in which to prepare the assessments, limited resources and expertise for performing assessments, poor data quality, lack of access to data, and lack of standard values for monetizing some benefits. As a result, while information on project benefits and costs was considered as one of many factors in the decision-making process, according to DOT officials, the varying quality and focus of assessments resulted in additional work, and the information provided was of limited usefulness to DOT decision makers. GAO recommends DOT conduct a data needs assessment to improve the effectiveness of modeling and analysis for rail and provide consistent requirements for assessing rail project benefits and costs. DOT, Amtrak and EPA provided technical comments, and DOT agreed to consider the recommendations.

Recommendations for Executive Action

  1. Status: Open

    Comments: In part as a result of this recommendation, the National Cooperative Rail Research Program (NCRRP) funded nine research efforts, five of which address data needs, cost-effective modeling, and analysis of intercity passenger rail. FRA expects that these research efforts will be complete in 2015. The main objectives of the five research efforts are as follows. NCRRP 03-01 Intercity Passenger Rail Service and Development Guide (5/2/13 - 11/1/14): develop a guide to assist public and private organizations as they plan, develop, and manage intercity passenger rail services. NCRRP 03-02 Intercity Passenger Rail in the Context of Dynamic Travel Markets (7/29/13 - 5/29/15): develop an analytical framework to improve understanding of how current or potential intercity travelers make the choice to travel by air, rail, bus, or private automobile for the majority of their trip. NCRRP 07-02 Developing Multi-State Institutions to Implement Intercity Passenger Rail Programs (6/10/15 - 2/9/15): create practical models for multi-state institutions that can have responsibility for developing and providing intercity passenger rail networks and services. NCRRP 02-01 Comparison of Passenger Rail Energy Consumption with Competing Modes (5/17/13 - 11/15/14): provide like-for-like comparisons of energy consumption and greenhouse gas emissions for commuter and intercity passenger rail operations and for competing travel modes. NCRRP 07-01 Alternative Financing Approaches for Passenger and Freight Rail Projects (4/23/13 - 2/22/15): identify alternative methods for financing passenger and freight rail project development, including capital investment, operations, and maintenance. This recommendation will remain open until some of these key research efforts are completed.

    Recommendation: To improve the data available to the Department of Transportation and rail project sponsors, the Secretary of Transportation, should, in consultation with Congress and other stakeholders, conduct a data needs assessment and identify which data are needed to conduct cost-effective modeling and analysis for intercity rail, determine limitations to the data used for inputs, and develop a strategy to address these limitations. In doing so, DOT should identify barriers to accessing existing data, consider whether authorization for additional data collection for intercity rail travel is warranted, and determine which entities shall be responsible for generating or collecting needed data.

    Agency Affected: Department of Transportation

  2. Status: Open

    Comments: In response to this recommendation, on June 5, 2014, a working group was convened to: (1) Share knowledge and best practices for Benefit Cost Analysis (BCA) across DOT modal administrations; (2) Review and validate FRA?s overall strategy and approach to BCAs for intercity rail projects; (3) Incorporate best practices and harmonize with TIGER and other DOT BCA initiatives; and (4) Assist in review of FRA?s future BCA guidance materials. FRA's final BCA guidance is expected to be completed in FY 2016. This recommendation will remain open until such guidance has been finalized.

    Recommendation: To improve the data available to the Department of Transportation and rail project sponsors, the Secretary of Transportation, should, in consultation with Congress and other stakeholders, Encourage effective decision making and enhance the usefulness of assessments of benefits and costs, for both intercity passenger and freight rail projects by providing ongoing guidance and training on developing benefit and cost information for rail projects and by providing more direct and consistent requirements for assessing benefits and costs across transportation funding programs. In doing so, DOT should: (1) Direct applicants to follow federal guidance outlined in both the Presidential Executive Order 12893 and OMB Circulars Nos. A-94 and A-4 in developing benefit and cost information. (2) Require applicants to clearly communicate their methodology for calculating project benefits and costs including information on assumptions underlying calculations, strengths and limitations of data used, and the level of uncertainty in estimates of project benefits and costs. (3) Ensure that applicants receive clear and consistent guidance on values to apply for key assumptions used to estimate potential project benefits and costs.
