• Transportation Resources

Transportation Sector Case Studies

These resources include case studies of adaptation in the transportation sector, developed by the Georgetown Climate Center as part of a cooperative agreement with the Federal Highway Administration. The case studies include examples of how adaptation has been incorporated into decisionmaking at all stages of the transportation lifecycle: assessing vulnerability, planning, design, and operations and maintenance.

Resources are automatically presented by rating, but can also be sorted by date and title. Apply additional filters to narrow the list by climate impact, region, transportation mode or stage of decision-making, state, or jurisdictional focus.

Adapting to Climate Change in Coastal Parks: Estimating the Exposure of Park Assets to 1 meter of Sea-Level Rise - Transportation Assets

May 2015

The National Park Service (NPS) produced this report assessing assets in coastal parks that may be threatened by a future one-meter rise in sea level. Over 10,000 assets were evaluated, including roads and trails, and 39 percent of assets (or $40 billion worth) in 40 coastal parks were designated as “high exposure. ” The report was intended to provide an overview of NPS' exposure to sea-level rise, but was not designed to inform decision-making about specific assets at the park-level. The analysis provides a methodology for assessing exposure of systems at a national or regional scale.

Hampton Roads Climate Change Adaptation Project

July 2012

Hampton Roads, Virginia engaged in a three-phase Climate Change Adaptation Project to identify impacts, assess the region’s vulnerabilities, and identify potential strategies for adapting to anticipated impacts. Part of the assessment focused on impacts to transportation infrastructure, although transportation impacts were only one issue of many analyzed in the three reports.

Development of a Methodology for the Assessment of Sea Level Rise Impacts on Florida’s Transportation Modes and Infrastructure

January 2012

This report provides a methodology for assessing the impacts of sea-level rise (SLR) on Florida transportation infrastructure. The report analyzes the advantages and disadvantages of different methods of forecasting SLR in Florida and provides recommendations for how those methods should be used by the Florida Department of Transportation (FDOT). The report also provides recommendations for identifying vulnerable transportation assets and addressing potential impacts of SLR to those assets. After this methodology was developed, FDOT funded a subsequent project to develop a GIS-based planning tool that aids in statewide and regional assessments of transportation asset vulnerability to SLR.

Responding to Climate Change in New York State: ClimAID – Transportation Chapter

November 2011

This state-level assessment provides information on New York's vulnerability to climate change and is specifically designed to assist in the development of adaptation strategies. The goal of the Integrated Assessment for Effective Climate Change Adaptation Strategies in New York State (ClimAID) is to provide decision-makers with progressive information on climate change effects on the state, and to facilitate adaptation planning. The ClimAID report reviews climate change impacts and adaptation options for eight sectors in New York including water resources, coastal zones, ecosystems, agriculture, energy, transportation, public health and telecommunications.

Sea Level Rise Vulnerability Study for the City of Los Angeles – Transportation Assets

December 2013

The University of Southern California Sea Grant Program completed a Sea Level Rise Vulnerability Study for the City of Los Angeles that summarizes initial research on the potential impacts of sea-level rise on Los Angeles’s coastal and shoreline assets, including the Port of Los Angeles, the Pacific Coast Highway and other significant coastal roads. The study identifies the Los Angeles (LA) communities and infrastructure most threatened, and offers a suite of adaptation measures including several specific recommendations for safeguarding transportation assets.

Alaska Highway Study: Groundwater Flow, Permafrost Degradation, and Transportation Infrastructure Stability

2013

The Alaska University Transportation Center (AUTC) of the University of Alaska, Fairbanks, supported a research project to study the effects of groundwater flow on permafrost degradation and resulting road instability. The stability of permafrost below roadways and embankments is increasingly affected by warming surface temperatures caused by climate change, but may also be affected by heat transfer from groundwater flow. Studies have shown that groundwater flow can accelerate permafrost degradation by several orders of magnitude compared to thaw caused by heat transfer from the atmosphere alone.

Climate Risk Assessment for United Kingdom's "High Speed Two" Rail Network

November 2013

The UK Government's proposed design for a new high speed railway between London and points north considered climate change-related risks, including flooding of tracks and overheating in tunnels. The risk assessment report discusses how those risks will be addressed in the proposed design for the project. The proposed project, High Speed Two (HS2), is designed to link eight of Britain’s ten largest cities and increase the capacity of the country’s rail infrastructure. The project is expected to cost 16 billion British pounds, with service to start in 2026.

Federal Triangle Stormwater Study

October 2011

The Federal Triangle Stormwater Drainage study analyzed the causes of a 2006 flood event that put the Federal Triangle Area of Washington D. C. under up to 3 feet of water, including several major traffic arteries, tunnels, and subway stations. The Study analyzes possible alternatives to reducing the risk of interior drainage flooding, including permeable pavements and other Low Impact Development (LID) techniques. In considering the causes of flooding in the area, the Study uses the 200-year flood as a proxy for assessing how climate change may increase flood risks and the frequency of severe storm events.

Resilience of New Jersey Transit (NJ TRANSIT) Assets to Climate Impacts

June 2012

This report assesses the potential vulnerability of New Jersey's state transit agency (NJ TRANSIT) stationary assets (rail, structures and buildings) to weather-related risks and projected climate impacts and identifies “cost-effective resilience strategies. ” While the assessment was underway, Hurricane Irene hit the state, causing $2 to $3 million in damages and losses in revenue and underscoring the need for NJ TRANSIT to plan for and build resilience against extreme weather events. The report quantifies the risks of a range of impacts to NJ TRANSIT assets given climate change scenarios over different planning timeframes (5, 10, 20 and 50 years).
