Global transportation infrastructure today is confronted with significant vulnerabilities — an aging infrastructure; a growing concentration of populations at high-density coastal urban areas; increasing interdependencies among the nation's physical and cyber infrastructures; co-location of many transportation systems with large-scale and potential

Across the globe, issues related to energy, its sources, uses, and impacts on climate change are at the forefront of political and environmental debates (e.g., the 2012 United Nations Climate Change Conference at Doha, http://unfccc.int). Currently, transportation accounts for approximately one third of greenhouse gas (GHG) emissions in the U.S., a

This project has focused on comparing alternative transportation technologies in terms of their environmental and economic impacts. The research is data-driven and quantitative, and examines the dynamics of impact. We have developed new theory and metrics to use in the forward-looking evaluation of a wide range of technologies. In particular, we ha

This project developed a series of three teaching cases that explore the implications of global warming for transportation policy in the United States. The cases are intended to be used in graduate and undergraduate courses on transportation policy and planning and are available free of charge from the website of the Case Program at the Harvard Ken

This paper is a deliverable on a technical support task for the FHWA Office of Operations. The objective of the task is to develop white papers on emerging and current topics of interest to the Office. Topics for white papers were primarily identified and prioritized based on internal listening sessions with Office of Operations personnel. This whi

This research study presents recommendations for the Arizona Department of Transportation (ADOT) to continue working toward being more resilient, flexible, and responsive to the effects of global climate change. The main objectives were to identify key individuals within ADOT with decision making authority relevant in incorporating climate change a
...
A warming climate has been identified as unequivocal by the Intergovernmental Panel on Climate Change with greater and faster temperature increase demonstrated at northern latitudes, and with an overall increase in precipitation. Analysis of field data collected throughout the arctic and subarctic corroborates with these findings, demonstrating an

This report provides an overview of diverse transit bus applications of advanced Lithium Ion Batteries (LIBs). The report highlights and illustrates several FTA programs that fostered the successful development, demonstration, and deployment of fuel-efficient hybrid-electric and electric drive transit buses in operational urban fleets over the last
...
The Federal Highway Administration's (FHWA's) Climate Change and Extreme Weather Vulnerability Assessment Framework is a guide for transportation agencies interested in assessing their vulnerability to climate change and extreme weather events. It gives an overview of key steps in conducting vulnerability assessments and uses in-practice examples t
...
Subsidence forecast models for coastal Louisiana were developed to estimate the change in surface elevations of evacuation routes for the years 2015, 2025, 2050, and 2100. Geophysical and anthropogenic subsidence estimates were derived from on-going empirical studies published in contemporary scientific literature. Forecasted elevation changes were

This analysis presents a “bottom up” projection of the potential production of alternative aviation (jet) fuels in North America (United States, Canada, and Mexico) and the European Union in the next decade. The analysis is based on available plans from individual companies and considers existing and emerging fuel production technologies. The analy

Successes in Stewardship is a Federal Highway Administration (FHWA) bimonthly newsletter highlighting current best practices in stewardship and environmental review from around the country.
Despite increasing confidence in global climate change projections in recent years, projections of climate effects at local scales remains scarce. Location-specific risks to transportation systems imposed by changes in climate are not yet well known. However, consideration of these long-term factors are highly relevant for infrastructure components

This synthesis and literature review requested by Seth Start, Sustainable Transportation Manager, Washington State Department of Transportation, provides information on strategies other state DOT's countries, and local agencies are using to prepare for climate change adaptation and mitigation of the impacts. This Synthesis gathered published inform

Increased congestion during peak morning and afternoon periods in urban areas is increasing logistics costs. In addition, environmental, social, and political pressures to limit the impacts associated with CO2 emissions are mounting rapidly. A key challenge for transportation agencies and businesses is to improve the efficiency of urban freight and
...
The Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) model was expanded to include aviation fuel production pathways and aircraft operations, allowing researchers to examine the environmental sustainability of various alternative aviation fuels. This report documents the expansion of the model to evaluate the life-cyc
