Monthly Transportation Statistics is a compilation of national statistics on transportation. The Bureau of Transportation Statistics brings together the latest data from across the Federal government and transportation industry. Monthly Transportation Statistics contains over 50 time series from nearly two dozen data sources.

About Transportation Services Index The Transportation Services Index (TSI), created by the U.S. Department of Transportation (DOT), Bureau of Transportation Statistics (BTS), measures the movement of freight and passengers. The index, which is seasonally adjusted, combines available data on freight traffic, as well as passenger travel, that have been weighted to yield a monthly measure of transportation services output. For charts and discussion on the relationship of the TSI to the economy, see our Transportation as an Economic Indicator: Transportation Services Index page (https://data.bts.gov/stories/s/TET-indicator-1/9czv-tjte) For release schedule see: https://www.bts.gov/newsroom/transportation-services-index-release-schedule About seasonally-adjusted data Statisticians use the process of seasonal-adjustment to uncover trends in data. Monthly data, for instance, are influenced by the number of days and the number of weekends in a month as well as by the timing of holidays and seasonal activity. These influences make it difficult to see underlying changes in the data. Statisticians use seasonal adjustment to control for these influences. Controlling of seasonal influences allows measurement of real monthly changes; short and long term patterns of growth or decline; and turning points. Data for one month can be compared to data for any other month in the series and the data series can be ranked to find high and low points. Any observed differences are “real” differences; that is, they are differences brought about by changes in the data and not brought about by a change in the number of days or weekends in the month, the occurrence or non-occurrence of a holiday, or seasonal activity.

Recognizing the importance of transportation and the importance of objective statistics for transportation decision-making, Congress requires the Director of the Bureau of Transportation Statistics (BTS) of the U.S. Department of Transportation (USDOT) to provide the Transportation Statistics Annual Report (TSAR) each year to Congress and the President.1 BTS published the first TSAR in 1994. This 30th TSAR edition documents the conduct of the duties of BTS as called out in the statute.Source: https://rosap.ntl.bts.gov/view/dot/79039The Transportation Statistics Annual Report (TSAR) describes the Nation’s transportation system, the system’s performance, its contributions to the economy, and its effects on people and the environment. This report is based on information collected or compiled by the Bureau of Transportation Statistics (BTS), a principle Federal statistical agency at the U.S. Department of Transportation.Source: https://www.bts.gov/product/transportation-statistics-annual-reportThis upload contains xlsx files supporting the 2023 (https://rosap.ntl.bts.gov/view/dot/72943) and 2024 (https://rosap.ntl.bts.gov/view/dot/79039) TSARs.The two readme files were created for this upload and were not produced by the BTS.

The Transportation Safety CD-ROM is another product in the BTS State and Metropolitan Analysis for Regional Transportation (SMART) series. The SMART project was conceived to assist metropolitan planning organizations (MPO)and state department of transportation (DOT) planners in responding to the increased requirements of the Intermodal Surface Transportation Efficiency Act (ISTEA) of 1991 and the Clean Air Act Amendment of 1990. The project is an experiment in communications that involves gathering the collective wisdom of the transportation planning community and making the materials generated by MPOs and DOTs easy to use and share.

The Transportation Safety CD-ROM contains over 200 safety-related reports, accident studies, award winning community programs, program planners, data sets and youth programs collected from MPOs, state DOTs, the federal government, and professional associations during the last quarter of 1995. Safety topics include rail, roadway, motor vehicles, transit, bicycle and pedestrian safety, and occupant protection.

The CD-ROM, Transportation Safety, has been released byt the Bureau of Transportation Statistics (BTS, "http://www.bts.gov" of the U.S. Department of Transportation (DOT). The CD-ROM is another product in the BTS State and Metropolitan Analysis for Regional Transporation (SMART) series. The SMART project is an experiment in communicatinos that involves gathering the collective wisdom of the transportation planning community and making the materials generated by MPOs and DOTs easy to use and share.

The following information about the CD-ROM was abstracted from the Bureau of Transportation Statistics Home Page:

The Directory of Transportation Data Sources, 1993, identifies 285 transportation data sources within the U.S. Department of Transportation and other Federal agencies. The purpose of the Directory is to provide users of transportation statistics with a comprehensive inventory of transportation data sources to effect easier accessibility to information. The Directory defines a data source as a computerized data base developed within the Federal government for internal and external use, as well as regularly scheduled or special printed statistical reports published by the Federal government that are not included on a computerized system. A new edition of the Directory of Transportation Data Sources will be available in February 1995 and will include information from the U.S. private transportation industry, Canadian and Mexican statistical agencies, as well as updated federal material. The Directory is also available on diskette as an executable file.

Government Transportation Financial Statistics is no longer being updated by the Bureau of Transportation Statistics as of June 2024!

It is being replaced by our new product, Transportation Public Financial Statistics (TPFS) which provides more granularity by expanding the categories of revenues and expenditures. The new dataset can be found: https://data.bts.gov/Research-and-Statistics/Transportation-Public-Financial-Statistics-TPFS-/6aiz-ybqx/about_data

Further information about the TPFS can be found at: https://www.bts.gov/tpfs

The government plays an important role in the U.S. transportation system, as a provider of transportation infrastructure and as an administrator and regulator of the system. The government spends a large amount of funds on building, rehabilitating, maintaining, operating, and administering the infrastructure system. Government revenue generated from several sources including user fees, taxes from transportation and non-transportation-related activities, borrowing, and grants from federal, state, and local governments primarily supports these activities.

Government Transportation Financial Statistics (GTFS) provides a set of maps, charts, and tables with information on transportation-related revenue and expenditures for all levels of government, including federal, state, and local, and for all modes of transportation.

Related tables can be found in National Transportation Statistics, Section 3.D - Government Finance (https://www.bts.gov/topics/national-transportation-statistics).

The Transportation Satellite Accounts (TSAs) provide a means for measuring the contribution of transportation services to the national economy. Prior to the TSAs, the magnitude of transportation services had long been underestimated, as most national measures counted only the value of for-hire services. Measurement of services provided only by for-hire firms misses the sizable contribution of transportation services that take place within nontransportation industries, termed as in-house transportation.To more accurately measure transportation services, the Bureau of Transportation Statistics (BTS) of the U.S. Department of Transportation and the Bureau of Economic Analysis (BEA) of the U.S. Department of Commerce, jointly developed the Transportation Satellite Accounts (TSAs). The TSAs, as a supplement to the U.S. Input-Output (I-O) Accounts, measure the contribution of both for-hire and in-house transportation. The TSAs include all seven of the for-hire transportation industries reported in the U.S. I-O accounts and four in-house transportation modes.

About seasonally-adjusted data

Statisticians use the process of seasonal-adjustment to uncover trends in data. Monthly data, for instance, are influenced by the number of days and the number of weekends in a month as well as by the timing of holidays and seasonal activity. These influences make it difficult to see underlying changes in the data. Statisticians use seasonal adjustment to control for these influences.

Controlling of seasonal influences allows measurement of real monthly changes; short and long term patterns of growth or decline; and turning points. Data for one month can be compared to data for any other month in the series and the data series can be ranked to find high and low points. Any observed differences are “real” differences; that is, they are differences brought about by changes in the data and not brought about by a change in the number of days or weekends in the month, the occurrence or non-occurrence of a holiday, or seasonal activity.

From https://www.bts.gov/faf:The Freight Analysis Framework (FAF) database provides estimates of US freight flows. The FAF provides data for states and metropolitan areas. Flows include all modes of transportation and 42 commodity types. The Bureau of Transportation Statistics (BTS) produces the FAF with support from the Federal Highway Administration (FHWA). BTS builds FAF with data from many sources. Inputs include the Commodity Flow Survey (CFS), foreign trade data, and data from agriculture, extraction, utility, construction, service, and other sectors.FAF5 includes three types of freight flows: weight, value and activity. The FAF provides weight in thousands of tons, value in millions of 2017 constant dollars, and activity in millions of ton-miles. Users can download .csv and Microsoft Access files below.The latest version of FAF (FAF5.6.1) provides estimates of weight, value, and activity by origin and destination regions, commodity type, and mode for:* Base year (2017)* Annual estimates (2018–2022)* Preliminary annual estimates (2023)* Forecast year estimates (2025–2050)* State-level historical trend estimates (1997–2012)* Experimental county-to-county estimates (2022) – the recently released experimental product (county-level flows) and documentationThe experimental county-to-county estimates are uploaded separately at https://www.datalumos.org/datalumos/project/231661/version/V1/view.From https://ops.fhwa.dot.gov/freight/freight_analysis/faf/:The Freight Analysis Framework (FAF), produced through a partnership between Bureau of Transportation Statistics (BTS) and Federal Highway Administration (FHWA), integrates data from a variety of sources to create a comprehensive picture of freight movement among states and major metropolitan areas by all modes of transportation. Starting with data from the 2017 Commodity Flow Survey (CFS) and international trade data from the Census Bureau, FAF version 5 (FAF5) incorporates data from agriculture, extraction, utility, construction, service, and other sectors.The FAF5 provides estimates for tonnage and value by regions of origin and destination, commodity type, and mode for base year 2017 and a 30- year forecasts. FAF5 forecasts provide a range of future freight demands at five-year increments representing three different economic growth scenarios, through 2050, by various modes of transportation.
