This paper presents results of an assessment of the state of research on "decoupling" the relationship between vehicle travel and economic growth.

Most environmental analyses focus on changing existing processes to use less energy and produce fewer emissions. This report uses energy service analysis (ESA) to examine possibilities for instead changing how a service is delivered. The ESA framework is used to analyze how changes in the provision of two services--news delivery and personal mobility--might reduce greenhouse-gas emissions and suggests other areas in which ESA could be applied.

The authors review traffic safety in the United States, with specific reference to military personnel, focusing on safety interventions and attempts to change driver behavior and decisions. This review discusses the safety interventions that tend to help in the reduction of vehicle crashes, especially those related to motorcyclists.
