Commuting is a daily necessity for many people, and driving alone is the most common mode of transportation to work in the United States. Environmental and individual health concerns are associated with driving: Motor vehicles contribute to air pollution, noise pollution, and, in many cases, transportation congestion. Congestion, common in large cities, creates concentrated air and noise pollution areas that disproportionately affect those of lower socioeconomic status. Long commutes can also increase the risk of high blood pressure, obesity and physical inactivity.
After housing expenses, vehicle maintenance (including purchasing, upkeep and operation) represents the second-largest expenditure for the average American household. By using public transportation and reducing the number of privately owned vehicles, a household can save about $13,000 a year. Additionally, switching from driving alone to using public transit to commute can reduce an individual's CO2 emissions by 20 pounds per day, more than 48,000 pounds per year. However, 45% of Americans have no access to public transportation, creating a gap in mobility and access. Studies have shown that improved public transportation access can increase employment opportunities, expand overall economic activity and decrease the amount of money households spend on transportation.
According to the American Driving Survey, populations that spend more time driving include:
Strategies to promote modes of transportation other than driving, particularly driving alone, include:
Healthy People 2030 has an objective to increase the percentage of trips to work made by mass transit.

America’s Health Rankings builds on the work of the United Health Foundation to draw attention to public health and better understand the health of various populations. Our platform provides relevant information that policymakers, public health officials, advocates and leaders can use to effect change in their communities.
We have developed detailed analyses on the health of key populations in the country, including women and children, seniors and those who have served in the U.S. Armed Forces, in addition to a deep dive into health disparities across the country.
