A colleague passed me this article.  It does a nice job of making the connection--in one page.

Driving better health through transportation

In the world of transportation, the focus is most often on creating mobility and accessibility. But according to Minnesota Department of Health Commissioner Edward Ehlinger, transportation also plays a major role in creating health. Delivering the keynote address at the 24th Annual CTS Transportation Research Conference, Ehlinger told the crowd, “Transportation is around us every day and influences everything we do, which makes it integral to creating the conditions for great health.”
