BTS Strategic Plan

Monday, October 26, 2020

October 2020


The Bureau of Transportation Statistics (BTS) of the U.S. Department of Transportation (DOT) provides timely, accurate, credible information on the U.S. transportation system, the movement of people and goods, and the consequences of transportation for the economy, society and the environment.


BTS is the preeminent source of statistics on multimodal freight movement and transportation economics, and a portal to understanding the transportation system and its consequences. BTS assures the credibility of its products and services through rigorous analysis, transparent data quality, and independence from political influence. BTS promotes innovative methods of data collection, analysis, visualization, and dissemination to improve operational efficiency, to examine emerging topics, and to create relevant and timely information products that foster understanding of transportation and its transformational role in society. The Bureau’s National Transportation Library (NTL) is the permanent, publicly accessible home for research publications from throughout the transportation community; the gateway to all DOT data; and the help line for the Congress, researchers, and the public for information about transportation.


Transportation is important for how it serves and affects individuals, businesses, the economy, the environment, and the nation. Statistics, maps, and their interpretation inform public and private decisions about transportation. BTS supports these decisions as a credible source of information that is free of perceived political bias.


While BTS has focused on creating a wide of useful products throughout its history, the mix of products and the method for creating products has changed significantly in recent years. BTS was established from a pre-Internet tradition of comprehensive transportation studies, reflected in the broad range of topics covered in each Transportation Statistics Annual Report. BTS focused on the creation of databases and tabulations to support printed reports, and depended heavily on surveys for source data. In response to evolving technology and user interests, BTS now emphasizes creation of interactive visualizations and other online data access tools to deliver statistical information in easily used modules over the Internet. Data come from a wider range of sources, and statistical products are designed to encourage ongoing analysis rather than be static reports.

Covid-19 demanded additional transformations in BTS products. Travel restrictions and warnings had enormous and immediate effects on the transportation system. BTS realized from anecdotal evidence that the speed and magnitude of change placed a premium on daily and weekly statistics rather than the Bureau’s traditional focus on annual and monthly statistics. The premium on timely statistics also demanded rethinking of deliberative product development processes with careful reviews of data quality. Preliminary estimates became more important than ever, just as the stable trends that formed the traditional basis for preliminary estimates were undone. BTS responded to these challenges by tapping new data sources, by taking different approaches to preliminary estimates, and by adopting a rapid prototyping strategy for statistical product development. Examples include The Week in Transportation web page and the daily statistics reported to the Secretary and other members of the DOT senior staff. These products were launched within days of inception using sources of data that were described as rough indicators and not fully vetted, and the content evolved in response to questions and suggestions by the users of the products.

Covid-19 also demanded transformation of BTS operations from an office with liberal telework to full-time work from home. After initial adjustments, BTS was able to maintain its products and services and increase its output with the development of new products.


The U.S. Department of Transportation Strategic Plan for FY 2018-2022 highlights data in general and BTS in particular as part of the Secretary’s strategic objectives for a systematic approach to safety, for improved infrastructure operations and performance, and for targeted infrastructure investments to support economic competitiveness (especially for freight and rural transportation). The Secretary’s strategic objectives for innovation encourage the use of data to identify and evaluate strategies and technologies. The Secretary’s strategic objectives for accountability emphasize streamlining processes, improving systems, and maximizing employee performance, development, and engagement to make efficient and effective use of the Department’s resources. These objectives are reinforced by the Foundations for Evidence-Based Policymaking Act (Pub.L. 115-435, Jan. 14, 2019). The ability of BTS to serve these objectives is supported by the Statistical Policy Directives of the Office of Management and Budget.

Beyond serving DOT, the Bureau’s authorizing legislation in Chapter 63 of Title 49, United States Code, directs BTS to serve the entire transportation community. This community includes state and local governments, private industry, and the public, creating a diverse range of customers with differing needs. Some are power users who want access to source data to build their own statistics and create their own maps. Some are experts in aspects of transportation who need guides to information on other facets of the subject that they are now confronting. Some have only personal experience in transportation and are looking for a story to increase their understanding of the topic. Many are looking for pre-made tables and maps to use in reports and analyses. All are looking for credible data that have adequate quality for their planned use of the data.

With the smallest budget of the principal federal statistical agencies, BTS must carefully manage resources to serve the Secretary’s strategic objectives, fulfill the Bureau’s legislated mandates, and meet a growing demand for transportation statistics with useful, timely, and credible products for a diverse range of customers. To achieve this balance, BTS will concentrate development of new or enhanced products in its core areas of expertise (freight, commercial aviation, and transportation economics); maintain the broad range of existing products and services that are either specifically required by law or meet customer expectations; and continue to investigate new methods of data collection, processing, analysis, quality assurance, dissemination, and preservation to enhance future products and services.


BTS currently includes the Director, Deputy Director, 6 office directors, a public affairs director, a technical director, 2 support staff, and approximately 50 statisticians, economists, and specialists in geo-spatial data, information technology, and library science.

While BTS has extensive expertise in many forms of data collection and analysis, deep knowledge of transportation across the wide range of subjects covered by BTS is limited. BTS is developing expertise in the emerging field of data science (including big data analytics).

BTS recognizes that recent adaptations to Covid-19 will affect the workplace of the future with greater dependence on remote operations. The ability to work from distant locations should improve recruitment of new talent, but reduced face-to-face contact will require new approaches to staff development and team cohesion.

In order to enhance staff expertise and the working environment, BTS will:

  • Recruit recent graduates for staff openings and through the BTS fellows program to expose BTS staff to new techniques and ideas for new products.
  • Provide training, temporary assignments, and other professional development opportunities to BTS staff to cultivate skills and capabilities needed by the Bureau.
  • Experiment with innovative ways to expose new and veteran staff to one another and maintain comradery during remote operations.


BTS depends on 2 sources of funding to support its activities:

  • Contract authority: BTS activities specified in Chapter 63 of Title 49, U.S. Code, are funded as an allocation from the Federal-aid Highway Program. Unlike budget authority that must be appropriated each year, funds under contract authority are authorized to be obligated and do not disappear at the end of the year. Current funding is $26 million per year.
  • Interagency agreements with external customers: the airline statistics program is funded through an agreement with the Federal Aviation Administration; the Confidential Close Calls Reporting Program is funded through agreements with the Washington Metropolitan Area Transit Authority and the Bureau of Safety and Environmental Enforcement of the U.S. Department of the Interior. BTS also receives funds from other agencies to support specific freight data products. Current reimbursable agreements total approximately $10 million per year.

The Bureau’s contract authority must be renewed with reauthorization of the surface transportation programs at the end of FY 2021. The reimbursable agreement with the Federal Aviation Administration is renewed annually; agreements with other customers are extended at the discretion of the customers.

BTS is authorized to sell products, and has exercised this authority only for restricted aviation data. Product sales raised approximately $17,000 per year, indicating that the commercial market for BTS products is small. Charging for unrestricted data products is not consistent with the Open Government Data Act of 2018 or with the Bureau’s longstanding philosophy of democratizing data by removing cost and other barriers to data availability.


BTS is part of four communities, each with its own set of partners and stakeholders:

  • The transportation community: BTS serves DOT as a source of statistical expertise and of objective information on transportation (especially from the perspective of system users rather than from suppliers of modal components); and BTS serves both DOT and the broader transportation community as a repository of research, data, and institutional knowledge through the NTL and the Bureau’s activities through partners like the Transportation Research Board.
  • Federal statistical agencies: BTS represents the transportation community on the Interagency Council on Statistical Policy, chaired by the Office of Management and Budget, and collaborates with individual federal statistical agencies such as the Census Bureau to meet the information needs of the transportation community.
  • Federal geographic data and mapping community: BTS is the principal integrator of geographic data related to transportation and works with a variety of organizations that develop and compile geo-spatial data to establish a high-quality, comprehensive, detailed electronic map of transportation that can be used throughout government and industry.
  • The knowledge management community: BTS works through the NTL with the Library of Congress, the National Library of Medicine, the National Agricultural Library, state DOT libraries, universities, and others to assure that transportation data, results of research relevant to transportation, and institutional memory are maintained and shared in forms that are readily accessible to the transportation community.


BTS provides varied statistics used throughout the transportation community as a foundation for planning, performance measurement, analysis, and research. A growing emphasis in the transportation community on performance management and evidence-based decisions places special demands on timely, detailed, accurate statistics. At the same time, open data initiatives and expanded numbers of users increase opportunities to reveal problems with the quality of data behind the statistics published by BTS and its partners. Quality is rarely an absolute, single value, and the requisite degree of data quality depends on how the data are used. To remain credible and useful, BTS must be transparent about the quality of its products and their fitness of use for various applications.

While the demands for data and statistics continue to grow, methods of collection are undergoing major change. Surveys remain a major source of data, but their cost-effectiveness is declining. The widespread replacement of paper with electronic transactions in businesses, the growth of on-line shopping, the exploding use of electronic sensors for controlling everything from vehicle engines to traffic signals, extensive coverage of cell phones, and the complete coverage of publicly available aerial imagery provide new sources of data on transportation and its consequences. These new data sources often involve unexplored privacy concerns, data sharing complications, poorly documented data quality problems, and data integration challenges. BTS programs and staff expertise must evolve to overcome the problems and take advantage of the new data sources.

In addition to its own data collection activities, BTS compiles data and statistics from a wide range of sources. In many cases, data are collected by state and local agencies and processed by another federal agency before the results are assembled into BTS products. When BTS identifies a questionable statistic from another source, BTS must decide whether or not to publish the statistic. If BTS includes questionable numbers in its publications, the Bureau encourages the transportation community and others to use potentially erroneous information and gets the blame if someone else confirms an error. If BTS excludes questionable statistics in its publications, the Bureau can appear to be incomplete or irrelevant. The proper approach often requires BTS to work through a long supply chain of data collectors and providers to validate or correct any questionable statistics. BTS must find ways to shorten data supply chains and enhance quality without alienating its data suppliers.


In the years ahead, BTS will be successful if it is recognized for delivering robust, credible, widely used products in each of the topic areas identified in legislative mandates and departmental goals. BTS products will be successful if they are recognized as inciteful, definitive, and objective. BTS will be a great place to work if the intellectual challenges are great, responses to the problems are creative and effective, and the Bureau’s products are useful and used throughout the nation.
