Breaking the Cycle of Automobile Dependency
Many current planning practices reinforce a cycle of increased automobile use, more automobile-oriented community redevelopment, and reduced mobility options. There are good reasons to break this pattern.
How Not To Measure Traffic Congestion, Redux Again
TomTom's annual traffic congestion rankings predictably generated horrified, self-pitying headlines about awful congestion in top-ranked cities. But there are big problems with their methodology.
Self-Fulfilling Automobile Dependency
Common planning practices create automobile-dependent communities where driving is convenient and other forms of travel are inefficient. It's time to recognize the value of transportation diversity.
Public Policies For Optimal Urban Development
What amount of expansion, population and vehicle densities, housing mix, and transport policies should growing cities aspire to achieve? This column summarizes my recent research that explores these, and related, issues.
Land for Vehicles or People?
Automobile-oriented planning requires that cities devote signifiant amounts of space to roads and parking—under many conditions each vehicle requires more land than is devoted to housing per capita.
Paradox: Congestion May Signify Better Accessibility and Economic Productivity
Although transport planners consider traffic congestion economically harmful, economic productivity tends to increase with congestion and decline with increased road supply. This paradox can be explained by more nuanced analysis of accessibility.
Meant to Deter, Utah's Bad Air Alerts Actually Increase Driving
Call it the law of unintended consequences. Alerts of "bad air days" that ask motorists in the Wasatch Front to reduce driving had the opposite effect, prompting some residents to drive away from lowlands to the mountains where air may be healthier.
Responding to Smart Growth Criticism
Critics claim that smart growth policies are ineffective at reducing vehicle travel and achieving intended to objectives. This column critiques their arguments.

Optimal Transport Policy For An Uncertain Future
As I write this column (2 February) the U.S. House Transportation Committee is debating changes in H.R. 3864, the American Energy and Infrastructure Jobs Act, which will determine future federal transportation policy.
