Policymakers at all levels of government are debating a wide range of options for addressing the nation's faltering economic conditions. One option that is once again receiving attention is accelerated investments in the nation's public infrastructure -- that is, highways, mass transit, airports, water supply and wastewater, and other facilities -- in order to create jobs while also promoting long-term economic growth. This book examines policy issues associated with using infrastructure as a mechanism to benefit economic recovery. Discussed are state-level driver data and the effect of look-back periods on recidivism prevalence; restraint use and minimum drinking age laws; electronic stability control; mobile device use while driving; the impact of fuel price increases on the aviation industry; aviation safety; and the assessment of potential mariner-training needs.
