Reddit mentions of Urban Sprawl and Public Health: Designing, Planning, and Building for Healthy Communities

On affordability: Both CNT's Housing + Transportation Index and the Brookings Institution's Affordability Index have found that transit access has a positive impact on affordability even when housing prices are factored in. For a quicker read, here's a CityLab article breaking down the data with charts.

On driverless cars: Here's a well-sourced AVs piece from leading expert Jarrett Walker, a review of studies showing ride-hailing's negative impact on transit, and some hard data from the Boston planning commission showing the same.

On transit and health: I would first recommend the seminal Urban Sprawl and Public Health. More recently, this study of transit and mental health, this one from AHA on transit and heart health, and a research overview from NIMH!

Bus improvements being in the plan is, well, in the plan — as are pike improvements. There's plenty out there on transit and economic growth, transit and disability, etc. Happy to help.

There is a huge body of work on the built environment and public health from both the planning profession and the public health profession. The following two books are good starting points:

• Health and Community Design: The Impact Of The Built Environment On Physical Activity
  
• Urban Sprawl and Public Health: Designing, Planning, and Building for Healthy Communities

There are definitely some statistics and figures in this book. It's available in paperback or Kindle, since it seems you have only a few days to prepare.
