Public Transportation Edition:
Ed Glaeser has an interesting article on how public transportation contributes to the concentration of poverty in urban areas. hat tip: Ryan Avent (Ryan Avent has a blog, the Bellows, that focuses on transportation and planning mostly as related to D.C. and is uniformly interesting).
The Ideas Primary, a sounding board for the DLC, has an interesting proposal on funding passenger rail (something we should do more of in my opinion at the expense of highway funding)
Ryan Avent pines for light rail in D.C. and a cross town metro line. I agree. Mandingo what say you?
Here is an interesting post on the proliferation of light rail in America over at The GoodSpeed Update.
