This study explores the relationship between vehicle occupancy and several other variables in the National Highway Traffic Safety Administration's (NHTSA) Fatality Analysis Reporting System (FARS) database and a 15-passenger van's risk of rollover. A univariate analysis is used to demonstrate the effect of selected variables on single-vehicle rollover crashes. Variables used include speed, number of occupants, driver experience and avoidance maneuvers. Also, a logistic regression model is constructed using data from NHTSA's State Data System a collection of all police reported crashes for that state. The resulting model permits jointly estimating the effect of these variables on the odds and rate of rollover occurrence, conditional on being in a single-vehicle police-reported crash.

Drive to Survive: The Art of Wheeling the Rig provides an in-depth examination of fire apparatus vehicle dynamics. This is not your average “driver training” textbook. Fire apparatus operators must understand how a vehicle maneuvers at roadway speed, and more importantly…why does it crash? Just as a doctor cannot heal the human body without a thorough understanding of anatomy and physiology, an emergency vehicle operator cannot safely drive a fire apparatus without an in-depth knowledge of vehicle dynamics. Drive to Survive goes beyond talking about pump operations, aerial operations, and preventative maintenance; it fills in the gaps between vehicle dynamics and crash causation. After 15 years of training and research, Chris Daly developed a training program combining his fire service and crash reconstruction training experience. This book provides an in-depth knowledge of topics required in the following NFPA standards: --NFPA 1002 “Standard for Fire Apparatus Driver/Operator Professional Qualifications” --NFPA 1451 “Standard for Fire and Emergency Service Vehicle Operations Training Programs” --NFPA 1500 “Standard on Fire Department Occupational Health and Safety Program” Fire apparatus operators will learn the limits of driving an emergency vehicle and will understand that no matter how long they have been driving or how good they think they are, at some point physics will take over and the vehicle will lose control. We can reduce the number of emergency vehicle crashes throughout the world by addressing key issues and providing emergency vehicle operations course (EVOC) instructors with methods to convey these concepts. Concepts you learn in this book relate to more than just driving a fire apparatus. These principles apply to anyone who drives a vehicle, including your family members and loved ones.

For years, reducing the number of traffic-related fatalities and injuries has been a major problem throughout the world. Today, it has gained much more momentum in view of rapidly increasing SUV, van, and light-truck populations relative to the number of passenger cars, and due to significant improvements in technologies that facilitate a better understanding of the interaction dynamics among widely differing size vehicles. Unless disparities in crashworthiness among vehicles of different masses, sizes, and structural characteristics in mixed crash environments are successfully taken into account, the challenge toward improved vehicle safety will continue. This two-part compendium provides the most comprehensive information available on the entire spectrum of vehicle crash compatibility. The first part presents oral comments captured from the 2003 SAE World Congress panel discussion on compatibility. The panel of leading experts representing industry, academia, and government provides a rough framework and a broad range of views on current and emerging developments in compatibility research. The second part of this compendium features 44 best technical papers from SAE International and the International Technical Conference on the Enhanced Safety of Vehicles, published from the early 1970s through 2004. Readers will get a feel for the direction passenger car and heavy-vehicle manufacturers, research institutions, infrastructure suppliers, insurers, and governments are taking to reduce the number of traffic fatalities and injuries.

Fifteen-passenger vans, which make up about 0.25 percent of the passenger vehicle fleet in the United States, are frequently used to transport school sports teams, van pools, church groups, and other groups. Although they are involved in a proportionate number of fatal accidents compared to their percentage in the fleet, they are involved in a higher number of single-vehicle accidents involving rollovers than are other passenger vehicles. Various factors have been associated with 15-passenger van rollover, particularly occupancy level and vehicle speed. Fully loading or nearly loading a 15-passenger van causes the center of gravity to move rearward and upward, which increases its rollover propensity and could increase the potential for driver loss of control in emergency maneuvers. The National Highway Traffic Safety Administration has been evaluating vehicle rollover for several years. The agency has initiated rulemaking activities concerning vehicle rollovers, established a rollover resistance rating system, and is currently examining dynamic testing procedures; however, these programs have not been extended to 15-passenger vans. As a result of this safety report, the National Transportation Safety Board issued safety recommendations to the National Highway Traffic Safety Administration and to the manufacturers of 15-passenger vans.

Examines the incidence rates of pedestrian and bicyclist crashes that involved hybrid electric vehicles (HEV) and compares the results to internal combustion engine (ICE) vehicles under similar circumstances. State crash files from the Nat. Highway Traffic Safety Admin.¿s State Data System were used to measure the incidence rates of pedestrian and bicyclist crashes by HEVs and to compare the incidence rate with their peer ICE vehicles. This study found that pedestrian and bicyclist crashes involving both HEVs and ICE vehicles commonly occurred on roadways, in zones with low speed limits, during daytime and in clear weather, with higher incidence rates for HEVs when compared to ICE vehicles.
