Welcome to Episode 29 of the Talking Headways podcast. In it, we evaluate the potential of Boston's attempt to "gentrification-proof" the Fairmount Line, building affordable housing to keep transit from displacing people with low incomes. Too often, the allure of transit raises rents, bringing in a new demographic of people who can pay them -- and who, ironically, usually have cars.

Yesterday, during the one-hour debate period over the House proposal to extend transportation funding through May 31, lawmaker after lawmaker stood up to condemn the bill. America needs a long-term transportation bill, they said. A short-term stopgap only creates more uncertainty.

All the buzz right now is about Arlington, Virginia -- the DC suburb has seen its population rise and its car traffic drop since the 1980s. How did they do it? It could be a lesson for Palo Alto, California, which is considering various growth proposals, including one that would invite greater density as long as it comes with no additional driving, carbon emissions, or water use.

While a six-year Senate transportation bill languishes in partisan purgatory, the House Ways and Means Committee has proposed an eight-month patch that would backfill the Highway Trust Fund until May 31, 2015. That would punt the transportation bill debate until a new Congress takes over -- one that’s expected to have Republican majorities in both chambers.

Summer is finally here, but livable streets advocates already can’t wait for September to come. The biennial Pro Walk/Pro Bike/Pro Place conference is taking place in Pittsburgh, a city that's shedding its "Rust Belt" image and emerging as a leader in progressive street design with the help of a new mayor who’s committed to biking, walking, and public space.

While most people know Walt Disney as the creator of lovable characters like Mickey Mouse and movies like "Snow White and the Seven Dwarfs" and "Fantasia," Disney doesn't get as much credit for his design of Disneyland. Turns out Disney made himself an expert on the subject.

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.

Last week, 371 mayors and other city leaders wrote a letter [PDF] to Sen. Barbara Boxer, chair of the Environment and Public Works Committee, in support of local control over transportation dollars for bike and pedestrian projects.

Did you wear your helmet when you biked to work this morning? Whether you did or you didn't, it's up to you. So why are there so many people shrieking about it? On one side, the 85-percenters, overstating the protection helmets offer against head injuries. On the other side, the 3-footers, claiming that it's actually safer to go helmetless because drivers give you more space and a host of other reasons. Some recent hysteria around bike-share and head injuries fueled this fire. I'm not sure Jeff and I put that fire out with our discussion, but we at least tried to make some sense of it.
