Studies & Reports

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. Second in a series.

You can’t put a price tag on human life. But to address the scourge of traffic violence, it helps to measure how much harm it inflicts. And the National Highway Traffic Safety Administration has done that by attaching a dollar figure to the economic loss and human suffering caused by traffic crashes. 

Walking should be the healthiest, most natural activity in the world. It is, after all, one of the first things humans learn to do.

Any bicyclist knows that maps can be quite deceiving at first glance. The first time I tried to traverse San Francisco on a bicycle, I foolishly set out from the bike-rental shop on Fisherman's Wharf with a basic street map, and decided that I'd avoid downtown traffic by heading south across the grid. While I was correct that the city's connected street grid offered many direct routes, I neglected to notice the huge ridge of Pacific Heights looming directly ahead, or the numerous full-stop intersections along the way that would further sap my momentum.

How good are your state's policies on walking and biking?

All across America, city buses are waiting. Waiting at stoplights, waiting behind long lines of cars, waiting to pull back into traffic, waiting at stops for growing crowds of passengers. And no, it's not just your imagination: Buses are doing more waiting, and less moving, than they used to. A recent survey of 11 urban transit systems conducted by Daniel Boyle for the Transportation Research Board found that increased traffic congestion is steadily eroding travel speeds: The average city bus route gets 0.45 percent slower every single year. That's especially discouraging given how slowly buses already move, with a typical bus averaging only 13.5 mph.

New data from the Alliance for Biking and Walking's 2014 Benchmarking report bears out the notion that people tend to be healthier in cities where walking and biking are more prevalent.

Which state has the highest share of people who walk to work? It's not temperate California.

The Alliance for Biking and Walking released its big biannual benchmarking report today, a 200-page document that measures the scope, status, and benefits of biking and walking across the United States, using 2011 and 2012 data to update its previous reports.
