Project Description

People who live in dense, walkable, transit-rich neighborhoods tend to drive less. This fact may seem intuitive to many transportation professionals, but why exactly is this the case?

Whatever the reasons, there may be implications for how we encourage more people to choose non-auto modes of travel.

So what is it? Is it the self-selection of people who prefer transit and walking, or something else entirely? To control for this selection bias, researchers looked to San Francisco housing lotteries to see what was the real cause, and they found a remarkably clear influencer: parking.
