Book Description
This study investigates the fatalities on the National Crash Severity Study (NCSS) of towaway, passenger car accidents. The analysis is in three stages. First, NCSS fatalities are compared to the fatally-injured occupants reported on the Fatal Accident Reporting System (FARS), as a tool for evaluating the representativeness of the NCSS data. Second, estimates of the probability of fatality for NCSS are computed for various conditions, such as the incidence of fire and the sex of the occupant. Third, in cases where two factors are highly correlated, such as is the case for rollover and ejection, modeling techniques are used to help quantify the effects of each variable. The results of this study suggest the following preliminary conclusions: (1) FARS and NCSS have similar distributions of many variables. These include urbanization, size of vehicles, type damage to vehicle, occupant seating location, sex, and restraint use. Differences resulting from the investigative methods and geographical areas of the two studies are identified and assessed. (2) On the NCSS file, many variables are associated with a much higher rate of fatality. These include (a) at the accident level: the number of vehicles involved, urbanization, and the incidence of fire or explosion; (b) at the vehicle level: the change of velocity at impact, the direction of the impacting force, and vehicle damage area; and (c) at the occupant level: seating position, age, sex, ejection, entrapment, and restraint use. (3) Rollover and ejection, which often occur together, are each independently associated with a higher rate of fatality. Of the two factors, ejection appears more related to a higher probability of fatality than does rollover alone. NCSS is the best currently-available source of accident data for analyzing injury-related factors. This report attempts to describe the accidents occurring in the NCSS sampling areas, and suggest ideas for further research.

Book Description
This report examined issues related to the ejection status of passenger vehicle occupants in fatal crashes. The tables are produced from data from the national highway Traffic Safety Administration's Fatality Analysis report Ing System (FARS) for the 5-year period from 2003 through 2007. The relationship between ejection status and the following factors are included in the report: Occupant restraint use, occupant injury severity, vehicle model year, speed limit at the location of the crash, rollover status, vehicle type, occupant age, occupant seat position, initial impact point, and number of vehicles involved in the crash.

Book Description
Data from the Fatality Analysis Reporting System (FARS) for the period 1994 2003 were used to compare the characteristics of fatal rural and urban crashes. The study found that there are approximately 42 percent more fatal crashes in rural areas compared to urban areas; however there are fewer vehicle miles traveled in rural areas than urban areas. In addition, fatal rural crashes are more likely to involve multiple fatalities, rollovers, and more trucks. Fatal rural crashes more often occur on curved roadways and have greater vehicle damage. Head-on crashes are more prevalent in rural areas than in urban areas. Finally, the length of time for emergency medical services to arrive at the scene is longer in rural areas than in urban areas.
