This report profiles the next generation of scenario planning for transportation practitioners. It provides a summary of the history, key benefits and driving issues that warrant a scenario-based approach. It includes a framework for scoping a scenario planning process tailored to specific issues and local agency capacity. It also illustrates the d

The goal of this research is to assess the greenhouse gas (GHG) emissions and air quality (AQ) impacts of transitions to advanced low‐NOx Compressed Natural Gas (CNG) engines in medium-duty vehicle (MDV) and heavy-duty vehicle (HDV) applications in California with a particular emphasis on renewable natural gas (RNG) as a fueling pathway. To evaluat

Extreme weather poses multifaceted hazards to transportation. There is now increased awareness of the threats of climate variability and change on transportation safety and state of good repair. In particular, a non-stationary climate will potentially change the frequency and severity of extreme events beyond those currently accounted for in design

The objective of this exploratory study is to develop a conceptual framework to identify critical transportation infrastructure and their vulnerability to natural hazards based on existing and available data specific to the Mississippi Gulf Coast. This particular study area has been selected based on its robust transportation network (2 airports, a

This research examines transit service and the combined effect of access and mobility on the use of sustainable (transit) and active transportation (bicycling and walking). A travel time metric with transit operational data is used to show how these modes interact under a low The relative effectiveness of automobile alternatives (i.e., buses, bicyc

This report summarizes a peer exchange on climate change resilience that was held October 4- 5, 2016 in Atlanta, Georgia and hosted by the Atlanta Regional Commission (ARC). The peer exchange was co-organized by the Federal Highway Administration (FHWA) and ARC. The transportation sector plays an important role in addressing climate change both thr

A series of recent severe weather events, including Hurricane Irene and Tropical Storm Lee, revealed vulnerabilities in New York State’s transportation system. Future extreme weather events are expected to place greater strain on regional transportation infrastructure, driving up operations, maintenance, and repair costs. In response to these event

Shoreline habitats and infrastructure are currently being affected by sea level rise (SLR) and as global temperatures continue to rise, will continue to get worse for millennia. Governments' and individuals' decisions to adapt to SLR could have profound consequences for adjacent ecosystems, transportation systems, and urban settings. The cost for t

The National Environmental Policy Act (NEPA) requires federal agencies to disclose and analyze the environmental effects of their proposed actions. The Federal Transit Administration (FTA) currently believes that assessing the effects of greenhouse gas (GHG) emissions and climate change for transit projects at a programmatic level is practicable. T

Climate change, already taking place, is expected to become more pronounced in the future. Current damage assessment models for extreme weather events, such as FEMA's Hazus, do not take the full impact to transportation systems into consideration. As a result, the consequences of climate change scenarios on freight transportation infrastructure and

Climate change is increasingly recognized as a threat to life on earth. “Continued emission of greenhouse gases will cause further warming and long-lasting changes in all components of the climate system, increasing the likelihood of severe, pervasive and irreversible impacts for people and ecosystems. Limiting climate change would require substant
