What's Driving all this Driving?
There are nearly twice as many Americans living in suburbs than living inside cities. For most of these people, the personal automobile is the transportation mode of choice, and often the only attractive option.
This work is focused on why we have observed so much housing growth in the suburbs, and hints at the policy changes that would be needed to reverse this trend. It briefly speculates on how differences in Gen Y (born after 1980) may (or may not) alter this trend. It concludes by showing how improvements in residential sustainability may look in the future, even if those residences are not in the urban core.

This talk generally addresses the urbanization and mobility trends in US metropolitan areas, and specifically describes an in-depth study of Denver, Colorado. (Denver was chosen through a criteria-based selection process to identify a "typical" growing US metropolitan area.) Maps of projected Denver housing and employment are presented, suggesting a growing importance of suburbs, highways, and personal automobiles to the area. First Presented at the Meeting of the Minds Conference, Boulder, CO, on September 23, 2011.
In the longer version, the slides include a study of Atlanta, Georgia. Atlanta is one of the fastest growing metropolitan areas in the US. The trends towards suburban growth are even stronger in Atlanta than Denver.
The slides also show general housing, employment, and transportation trends for the whole US.
