21st Century Transportation

Efficient public transportation systems like intercity rail and clean bus systems would make America’s transportation future better for everyone by reducing traffic congestion and pollution and increasing our options for getting around.

Reforming our broken transportation system

Changing Transportation: U.S. PIRG's series of reports on the dramatic changes underway in how Americans travel.

In the 20th century, Americans fell in love with the car. Driving a car became a rite of passage. Owning a car became a symbol of American freedom and mobility. And so we invested in a network of interstate highways that facilitated travel and connected the nation.

Now we're in a new century, with new challenges and new transportation needs. We still love our cars, but they remind us of our dependence on foreign oil. Americans want choices for getting to work, school, shopping and more. With gas prices up and lifestyles changing, Americans — especially the young — are driving less.

We need a transportation system that reflects and supports the way we want to travel now.


For six decades, the number of miles driven by Americans was on the rise year after year after year. Since 2004, Americans reversed the trend and have been driving less. Meanwhile, public transportation ridership nationwide is hitting record highs. This trend is greatest among younger Americans — who will be the biggest users of infrastructure built today. Since the 1950s — despite knowing that buses and rail use far less energy and space — we have spent nine times more on highway projects than on public transportation. 

By reducing traffic and pollution and increasing our options for getting around, efficient public transportation systems like intercity rail and clean bus systems would make America’s transportation future better for everyone.

But America also needs to repair and maintain our current aging infrastructure. Nearly 70,000 of the nation’s bridges are classified as “structurally deficient.” Instead of building ever-wider roads that will only make America more dependent on oil, we need to be smart in how we invest in highways, and fix them first.

The good news is that the public is in many ways ahead of Congress in leading the way toward reform. Help us make sure government recognizes our need to invest in a 21st century transportation system.

New Study Finds Technology Enabling Americans to Drive Less

In a first-of-its-kind study, U.S. PIRG compiled nation-wide evidence on transportation apps and vehicle sharing programs, and found that these advanced new tools have made it easier for Americans to drive less. Real-time apps and on-board wi-fi for public transit, as well as carsharing, bikesharing and ridesharing have spread rapidly in recent years while driving has declined. The report examines new evidence on how these practices are changing travel behavior.

New Study Reveals Driving on the Decline in 46 States

Americans have cut their per-person driving miles in 46 states plus Washington, D.C., since the middle of the last decade. The states with the biggest reductions in driving miles generally were not the states hit hardest by the economic downturn. The majority—almost three-quarters—of the states where per-person driving miles declined more quickly than the national average actually saw smaller increases in unemployment compared to the rest of the nation.

Moving Off the Road

Forty-six states plus the District of Columbia witnessed a reduction in the average number of driving miles per person since the end of the national Driving Boom. The evidence suggests that the nation’s per-capita decline in driving cannot be dismissed as a temporary side effect of the recession.

New Report: Reduction in Driving Likely to Continue

As the average number of miles driven by Americans heads into its eighth year of decline, a new report from the U.S. PIRG Education Fund finds that the slowdown in driving is likely to continue. Baby Boomers are moving out of the phase in their life when they do the most commuting, while driving-averse Millennials move into that phase. These demographic changes and other factors will likely keep driving down for decades. Download our infographic for a visual presentation of the report’s chief findings.
