The U.S. transportation system is essential to moving people and goods. It includes: 1. Infrastructure, such as airports, train stations, roads, bridges, pipelines, and bike trails. 2. Vehicles, including cars, buses, trucks, trains, ships, and aircraft. 3. People, including equipment operators, designers, builders, and transportation officials. Al...
Climate change may affect transportation at local, regional, and national scales. Three key impacts are described in this section.
Transportation is critical to the nation’s economy. It links homes, workplaces, and communities. It supports tourism and provides a lifeline during emergencies. It also connects manufacturers with supplies and consumers with essential goods and products. In 2020, the demand for transportation services contributed about $1.6 trillion to the U.S. gro...
Some groups are particularly vulnerable to climate change impacts on transportation. For example, more than 25 million Americans have disabilities that make traveling outside their home difficult.31 People with disabilities are more likely to use public transit, so they can be greatly affected when these services are disrupted.32 Low-income househo...
Municipal, state, and national leaders—as well as individuals—can reduce climate change’s impacts on transportation in many ways, including the following: 1. Build resilience. Communities and transportation agencies can assess risks to their transportation systems, consider solutions, and take action. 2. Support smart transportation options. The wa...
