Toward understanding the recent large reductions in U.S. road fatalities
From 2005 to 2009, U.S. road fatalities dropped by 22% (from 43,510 to 33,963). A reduction of such magnitude over such a short time has not occurred since road-safety statistics were first kept (starting in 1913), except for the reductions during World War II. The present study was performed to...
Drivers on unfamiliar roads and traffic crashes
This study was designed to investigate whether there is an increased risk of traffic crashes in the U.S. for out-of-state drivers-those drivers whose driver license was not issued by the state in which they were involved in a crash. Two analyses were performed. In the first analysis, we examined...
Survival in fatal road crashes body mass index, gender, and safety belt use.
Background: This study evaluated the associations of body mass index (BMI), gender, and use of safety belts with the survival of drivers involved in fatal road crashes. Method: The census data of all U.S. fatal crashes that did not involve pedestrians, bicyclists, or motorcyclists were examined for...

Interactions of environmental and safety measures for sustainable road transportation
Purpose: This study examined interactions of environmental and safety measures for road transportation. Method: Road-safety effects of various measures targeting environmental problems of road transportation and environmental effects of various road-safety measures were reviewed. Results: The...
Recent major improvements in road safety in the U.S changes in the frequency of crashes or the severity of the outcome of crashes?.
This study introduced a new methodology for evaluating the relative contributions of the changes in the frequency of crashes and the severity of the outcome of crashes to the recent large improvement in road safety in the U.S. The approach is based on a parallel examination of changes in variables...

Objective: This study examined the recent changes in the percentage of persons with a driver's license in 15 countries as a function of age. Method: The countries included were Canada, Finland, Germany, Great Britain, Israel, Japan, Latvia, The Netherlands, Norway, Poland, South Korea, Spain,...
Recent changes in the age composition of U.S. drivers implications for the extent, safety, and environmental consequences of personal transportation.
This study examined the changes from 1983 to 2008 in the percentage of persons with a driver-s license as a function of age. The results indicate that, over the past 25 years, there was a substantial decrease in the percentage of young people with a driver-s license, and a substantial increase in...
