Transit Benefit Data and Analysis
These reports present data and analysis concerning the benefits of transit use for the economy, environment, and the well being of transit riders and their communities. Additional reports on these topics can be found in the Reports and Publications pages of the APTA web site.
Energy and Environment Benefits
- The Route to Carbon and Energy Savings - November 2010
This report identifies a portfolio of strategies that transit agencies can take to reduce the energy use and GHG emissions of their operations and estimates the potential impacts of those strategies in 2030 and 2050. Using interviews and current literature, a portfolio of 17 high-priority strategies were selected for analysis based on their potential for reducing GHG emissions over the medium and long term.
- Quantifying Greenhouse Gas Emissions from Transit - August 2009
This Recommended Practice provides guidance to transit agencies for quantifying their greenhouse gas emissions, including both emissions generated by transit and the potential reduction of emissions through efficiency and displacement by laying out a standard methodology for transit agencies to report their greenhouse gas emissions in a transparent, consistent and cost-effective manner.
- The Broader Connection between Public Transportation, Energy Conservation and Greenhouse Gas Reduction - February 2008
Land use and travel impacts of transit service result in energy use reduction and greenhouse gas emission reductions greater than those measured by a simple comparison of transit and private vehicles energy use and emission rates.
- Public Transportation’s Contribution To U.S. Greenhouse Gas Reduction - September 2007
This report will answers how much net C02 is public transportation saving in the U.S., how much additional C02 savings are possible if loads are increased, what is the significance of non-public transportation commuter use and what can households do to save more, and finally are there favorable land use impacts that public transportation contributes to the environment and social benefits?
- Public Transportation and Petroleum Savings in the U.S. Reducing Dependence on Oil - January 2007
This Independent analysis looks for the first time at what public transportation saves—both for individual households and for the nation as a whole. In addition, it explores a possible future where many more Americans would have the choice to take public transportation. APTA commissioned the report from ICF International.
Economy and Employment Benefits
- 2011 Urban Mobility Report - September 2011
This annual report by the Texas transportation Institute at Texas A&M University documents the cost of congestion on America's roads. The savings in dollars, lost time, and wasted fuel that result from transit se are documented.
- Economic Impact Of Public Transportation Investment - October 2009
This report estimates the economic impact of transit service including jobs supported by type, value added to the economy, business sales output, labor income, and added tax revenue.

- Job Impacts of Spending on Public Transportation: an Update - April 2009
This document reviews and updates estimates of the job impacts of public transportation spending and it examines broader issues concerning the definition and measurement of those job impacts.
- Optimal Supply and Demand for Urban Transit in the United States - February 2008
This report estimates the economic and social benefits of bringing transit to the optimal level of supply.
- Healthy Returns: The Economic Impact of Public Investment in Surface Transportation - March 2005
America’s highways, roads and public transportation systems contribute to virtually everything of value in our economy and lives – from linking businesses to their suppliers and customers, to bringing jobs, education, health care, recreation and government services within every American’s reach. This report measures those benefits and the costs required to achieve them.
- Public Transportation and the Nation’s Economy - October 1999
Using state-of-the-art analytic techniques, this study affirms the significant positive economic impact of transit investments on jobs and business revenue. An early analysis using sophisticated modeling techniques, this report verifies the continued positive results of studies about transit economic benefits.
- Transportation Spending and Economic Growth: The Effects of Transit and Highway Expenditures - September 1991
An analytical report by Dr. David Alan Aschauer, Senior Economist, Federal Reserve Bank of Chicago, explains why one way to generate higher productivity growth is through increased funding for transportation, in general, and for public transit in particular. This early analysis of transit benefits shows the consistent positive economic impact of transit using changing analytical methodologies.
- Evaluating Public Transportation Health Benefits - June 2010
This report by Todd Litman investigates ways that public transportation affects human health, and ways to incorporate these impacts into transport policy and planning decisions. This research indicates that public transit improvements and more transit oriented development can provide large but often overlooked health benefits.

- Rail Transit in America: A Comprehensive Evaluation of Benefits - 2004 (Litman, Todd)
This report quantifies the benefits of rail transit based on a comprehensive analysis of system performance. The analysis indicates that rail transit investments are a cost-effective way to improve urban transport, and shows that rail transit systems provide a variety of economic, social and environmental benefits that tend to increase as a system expands and matures.
