In SAFETEA-LU Section 1808, Congress required the U.S. Department of Transportation, in consultation with the Environmental Protection Agency, to evaluate and assess the direct and indirect impacts of a representative sample of Congestion Mitigation and Air Quality-funded projects on air quality and congestion levels.

The Drug and Alcohol Testing Results 2000 Annual Report is compilation and analysis of drug and alcohol testing results reported by transit systems in the United States 2000. The report covers results for the following drug types: marijuana, cocaine, phencyclidine, opiates, and amphetamines.

The Transit and Security Statistics and Analysis 2000 Annual Report is a compilation and analysis of mass transit accident, casualty, and crime statistics under the Federal Transit Administration's National Transit Database Reporting System by transit systems in the United States during 2000.

High-speed trains in the speed range of 100 to 160 mph require tracks of nearly perfect geometry and mechanical uniformity, when subjected to moving wheel loads. Therefore, this report briefly describes the remedies being used by carious railroads to create smoothed transition regions.

Transportation agencies use a variety of metrics to document progress toward achieving specific goals and objectives. This guide, developed by Federal Highway Administration's (FHWA) Planning and Environmental Linkages (PEL) program, is intended to help State Departments of Transportation (DOTs), metropolitan planning organizations (MPOs), and local transportation agencies develop individual programs to measure success toward linking transportation planning and environmental analysis. This guide provides a framework for establishing measures that transportation agencies can utilize to develop...

"Property management" in the highway transportation context refers to the administration of property acquired for highway purposes to ensure that the public interest is served. The properties that State Departments of Transportation (SDOTs) oversee are valuable resources that need to be managed in order to safeguard the safe and efficient functioning of highway improvements and their related facilities. For that reason, each SDOT has the responsibility to maintain, lease, or sell its properties and to keep an inventory identifying where such lands are located.

The Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) included provisions intended to enhance the consideration of environmental issues and impacts within the transportation planning process. Through the provisions, which encourage the continued evolution of the metropolitan and statewide transportation planning processes that metropolitan planning organizations (MPOs), State Departments of Transportation (DOTs), and public transit operators conduct, many of the types of activities previously considered effective practice became required for the...

The report describes a risk-based approach for assessing the implications of higher train speeds on highway-railroad grade crossing safety, and allocating limited resources to best reduce this risk. Toe prevent accident frequency, and existing DOT model was extend to include higher speeds.

This report will improve understanding of how states and localities might contribute to greenhouse gas (GHG) emissions reduction through transportation planning. Transportation is a major contributor to GHG emissions. State and local transportation planning affects transportation decisions, which, in turn, can influence travel patterns, land use, energy consumption, and, ultimately, GHG emissions.

The U.S. Department of the Interior (DOI), National Park Service (NPS), and the U.S. Departmentof Transportation (DOT), Federal Aviation Administration (FAA) are jointly sponsoring a study toexamine the accuracy of existing models used for predicting tour aircraft noise in Grand CanyonNational Park (GCNP). In particular, three models will be included in the study: the NPS' NoiseOverflight Decision Support System (NODSS), the FAA's Integrated Noise Model (INM), and athird model, the Noisemap Simulation Model (NMSIM), which has been developed with fundingfrom both the U.S. Air Force and the...
