How can you turn a car-dependent city into a place where most people feel safe cycling for transportation?

All across America, cities are investing in new transit lines. Which of these routes will make the biggest impact by attracting large numbers of new riders? A landmark report from a team of researchers with the University of California at Berkeley identifies the factors that set successful transit investments apart from the rest.

Nine years after launching a program to measure the impact of bike and pedestrian investments in four communities, the Federal Highway Administration credits the program with increasing walking trips by nearly a quarter and biking trips by nearly half, while averting 85 million miles of driving since its inception.

A Washington Post headline proclaimed today that cyclist head injuries have increased in cities with bike-share systems, based on a study published in the American Journal of Public Health. But University of British Columbia public health professor Kay Ann Teschke is challenging that conclusion, pointing out that the data cited by the WaPo actually leads to the opposite conclusion: In cities with bike-share systems, head injuries and injuries of all kinds have gone down.

Americans are increasingly sorted along ideological lines. There is less diversity of opinion among the people we associate with, in the media we consume, and even where we want to live. That's according to a new report from Pew Research Center studying political polarization in the United States.

The first decade of the millennium saw significant growth for transit in America.

Michael Andersen blogs for The Green Lane Project, a PeopleForBikes program that helps U.S. cities build better bike lanes to create low-stress streets. Fifth in a series.

A new academic study helps explain the enduring political popularity of expensive transportation boondoggles like Birmingham's $4.7 billion Northern Beltline and Kentucky's $2.6 billion Ohio River Bridges.

If you like painted bike lanes, you'll probably love protected bike lanes.
