Increases in bicycling in the United States result in increased exposure to crashes and injuries. This research focuses on the factors involved in bicycle crashes in the United States and the state of Iowa. Data from the U.S. Nationwide Inpatient Sample and the Iowa Department of Transportation were used to address three aims: 1) estimate the burden and examine the outcomes of bicycle crashes r...

While it has been known for some time that crashes can result from the driver falling asleep at the wheel, this issue has received less attention in traffic safety programs than the role of alcohol or speed of the vehicle. The present study was done to investigate the characteristics of crashes attributed to the driver being asleep. The study utilized the database at the Highway Safety Research...

OBJECTIVES Older drivers have become a larger part of the driving population and will continue to do so as the baby boomers reach retirement age. The purpose of this study was to identify the potential effects of this population increase on highway safety. METHODS Driver involvement rates for all police reported crashes were calculated per capita, per licensed driver, and per vehicle-mile of ...

This report describes young driver crashes in Alaska, compares rates and characteristics of young driver crashes with adult driver crashes, and summarizes the medical and financial outcomes of young driver crashes, for the period 1991 through 1995. Using the Mini Crash Outcome Data Evaluation System (MINICODES), trauma registry hospital discharge data were linked with traffic crash records. The...

BACKGROUND The purpose of this article is to draw attention to a significant role of social approval variable in the qustionnaire-based diagnosis of drivers' psychological aptitude. MATERIAL AND METHODS Three questionnaires were used: Formal Characteristics of Behavior - Temperament Inventory (FCB-TI), Eysenck Personality Questionnaire (EPQ-R(S) and Impulsiveness Questionnaire (Impulsiveness,...

BACKGROUND Approximately 1 in 4 children hospitalized with injuries from traffic crashes and their parents experience symptoms of acute stress disorder (ASD). These families represent a minority of those exposed to the trauma of a crash. To date, no studies have explored the prevalence of ASD symptoms in the broader population of children and parents exposed to crashes. OBJECTIVE To describe ...

Introduction: This study presents a classification tree based alternative to crash frequency analysis for analyzing crashes on mid block segments of multilane arterials. Method: The traditional approach of modeling counts of crashes that occur over a period of time works well for intersection crashes where each intersection itself provides a well defined unit over which to aggregate the crash d...

BACKGROUND Tractors and other slow-moving self-propelled farm equipment are often used on public roadway to transfer goods from the farm to a market or distributer. Increased roadway exposure has led to a growing concern on the occurrence of farm equipment crashes. This study aims to compare characteristics of road segments with farm equipment crashes to road segments without farm equipment cra...

This study set out to examine the effects of studded tires on fatal crashes on roads covered with ice or snow in Sweden and also to investigate the extra benefits of electronic stability control (ESC) during the winter months. Two different studies are presented in this paper. Both studies used an induced exposure approach. In the main study, 369 in-depth studies of fatal crashes with passenger...

We obtained data from the French Ministry of Transport on all road crashes during 1994-8 (640 670) in which at least one person was severely injured (confirmed by paramedics) or died. Crashes were attended by police officers, who completed a standard ministry questionnaire that covered time of incident, location, road and weather conditions, vehicles involved, mechanical defects, health of driv...
