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.
This report aims to characterize the drivers, infrastructure, and
environment associated with fatal motor vehicle traffic crashes
that occur at roadway intersections in the United States. Trends of
these characteristics have been presented for the eight-year period
from 1997 to 2004, the latest year for which such data was
available at the time of this analysis. Of particular interest are
the type and condition of traffic control devices present at the
intersection, potential driver and environment-related contributing
factors, as well as violations that were charged to the drivers
involved in the crashes.
The purpose of this document is to inform users of NHTSA's fatality
Analysis Reporting System (FARS) and National Automotive Sampling
System General Estimates System (NASS GES) data about some of the
more significant changes to the 2010 data as a result of the
standardization of the data elements between the two systems.
In this annual report, Traffic Safety Facts 2009: A Compilation of
Motor Vehicle Crash Data from the Fatality Analysis Reporting
System and the General Estimates System, the National Highway
Traffic Safety Administration (NHTSA) presents descriptive
statistics about traffic crashes of all severities, from those that
result in property damage to those that result in the loss of human
life.
MMUCC s a guideline that presents a model minimum set of uniform
variables or data elements for describing a motor vehicle traffic
crash. The use of MMUCC data elements will generate data that can
be employed to make more informed decisions which will lead to
improvements in safety and at the national, State and local levels.
This five-year plan for the Evaluation Division of the Office of
Regulatory Analysis and Evaluation (ORAE) in NHTSA's National
Center for Statistics and Analysis presents and discusses the
vehicle and behavioral programs, regulations, technologies and
related areas ORAE proposes to evaluate, and it summarizes the
findings of ORAE's past evaluations.
A template of pre-crash scenarios is presented to depict national
crash statistics and kinematic information of time-to-collision for
the design of appropriate crash countermeasures based on
vehicle-to-vehicle (V2V) communications. This template serves the
development of functional requirements, performance specifications,
test procedures, and benefits estimation for potential
light-vehicle V2V safety applications. A set of ten pre-crash
scenarios is suggested as a priority list to be addressed by V2V
technology for light vehicles (i.e., passenger cars, vans and
minivans, sport utility vehicles, and light pickup trucks with
gross vehicle weight ratings of 10,000 pounds or less). This report
presents the time-to-collision equations as well as the crash
statistics for each of the ten priority scenarios based on data
available in the General Estimates System, National Motor Vehicle
Crash Causation Survey, and Event Data Recorder databases.

his interim report describes the preliminary findings of the first
year of a two-year NHTSA-finded study which focused on three
topics: 1) emergency exits, 2) interior and exterior emergency exit
markings, and 3) emergency exit lighting.

This report describes the current efforts States are undertaking to
promote motorcycle safety, drawing on a survey received from State
Highway Safety Offices (SHSOs) and State motorcycle safety
administrators (SMSAs) in 45 States. The results presented in this
report provide a picture of recent accomplishments made by States
related to motorcycle safety. The data presented is based on
State-level, self-reported information.
The Fatality Analysis Reporting System (FARS) is the National
Highway Traffic Safety Administration's census of motor vehicle
crash fatalities in the United States and its territories. This
paper seeks to explain the implementation of the re-coding process,
in which previously entered cases were sampled and re-coded by
select, experienced FARS analysts to check the accuracy and
performance of the original analysts. The goal of the re-coding
process is to enhance the quality control process to maintain
accurate, complete, and timely FARS data.
This report examines the relationship between motorcycle helmet use
and motorcycle crash outcomes in terms of injury types, hospital
charges, and other variables employing data from the Crash Outcome
Data Evaluation System (CODES), a program facilitated by the
National Highway Traffic Safety Administration.
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.
Federal Motor Vehicle Safety Standard (FMVSS) 201 - Occupant
Protection in Interior Impact - was upgraded in 1995, with a
1998-2002 phase-in, to reduce occupants' risk of head injury from
contact during crashes with a vehicle's upper interior, including
its pillars, roof headers and side rails, and the upper roof.
Initially, energy-absorbing materials alone were used to meet the
standard; later, some vehicles were also equipped with
head-protection air bags. NHTSA does not yet have enough crash data
to evaluate the injury-reducing effectiveness of the
energy-absorbing materials. However, the agency has conducted 154
matched pairs of impact tests with free-motion headforms in pre-
and post-standard vehicles of 15 selected make-models.
NHTSA conducted a survey from April to October 2005 to collect
information about the types of restraint systems that were being
used to keep children safe while riding in passenger vehicles. In
particular, NHTSA was interested in whether drivers with Lower
Anchors and Tethers for Children (LATCH)- equipped vehicles were
using LATCH to secure their child safety seats to the vehicle, and
if so, were these seats properly installed. The make/model and the
type of restraint installed in each seating position were recorded
for each of the vehicles; demographic characteristics and the type
of restraint system were collected for each occupant. In addition,
information was gathered about the drivers' knowledge of booster
seats and LATCH, along with their opinions on how easy it was to
use LATCH.
