Bicycling

Bike-share has exploded in the last decade -- and in North America, just in the last few years. What started as a shaky concept in Amsterdam in the 1960s has matured into a viable transit option worldwide, with 600 systems offering more than 600,000 bikes.

In this week's podcast, Jeff and I discuss the impressive turnout -- and possible pitfalls -- of London's "die-in" demonstration for bike safety. We try to contain our envy (but not our amazement) at Paul Salopek's seven-year walk tracing the path of Homo sapiens from the Rift Valley to Tierra del Fuego. And we discuss why even passionate transit advocates know what it means to be embarrassed about taking the bus.

The long-term decline of walking and biking to school has been linked to the childhood obesity epidemic, a big share of morning rush hour traffic, and even kids' lack of attention in class. In 1969, 41 percent of children in grades K–8 lived within one mile of school, and of those kids, 89 percent usually walked or biked. By 2009, 31 percent lived within a mile of school -- and only 35 percent of them walked or biked.

Here's yet another story illustrating why we have an obesity problem in the United States.

This table, showing the top 10 U.S. cities where cycling is growing fastest, comes from a new report from the League of American Bicyclists that analyzes census data. Though the census only tracks bicycle commuting -- and thus understates how many people are cycling -- the results tell an interesting story about cycling trends.

Law professor Frank H. Buckley seems to want to be the next Dororthy Rabinowitz. That is, he wants to gain notoriety by clinging to old and unsafe street designs while, simultaneously, shoring up the Wall Street Journal's reputation as a bastion of change-averse curmudgeons. Done and done.

Behold, Streetsblog's brand-new podcast! In what we aim to turn into a recurring feature, Reconnecting America's Jeff Wood and I recently chatted about the week's news in livable streets, urbanism, and sustainable transportation. The topics are drawn from Jeff's excellent daily compendium of transportation and planning links, The Direct Transfer, and from stories we're tracking at Streetsblog Capitol Hill. It's a treat for me to get back to producing audio -- I was a radio reporter before joining Streetsblog.
