Safety Changes in the US Vehicle Fleet since Model Year 1990, Based on NASS Data.
Authors: Eigen AM, Digges K, Samaha RR Abstract Based on the National Automotive Sampling System Crashworthiness Data System since the 1988-1992 model years, there has been a reduction in the MAIS 3+ injury rate and the Mean HARM for all crash modes. The largest improvement in vehicle safety has been in rollovers. There was an increase in the rollover injury rate in the 1993-1998 model year period, but a reduction since then. When comparing vehicles of the model year 1993 to 1998 with later model vehicles, the most profound difference was the reduction of rollover frequency for SUV's - down more than 20% w...

Impact and injury patterns in between-rails frontal crashes of vehicles with good ratings for frontal crash protection.
This study analyzed the type of object that caused the direct damage between the rails, including small tree or post, large tree or pole, and another vehicle; and found that the struck object was most often another vehicle or a large tree/pole. Both the extent of damage and the occupant compartment intrusion were explored, and suggest that 64% of the serious injuries are associated with increasing intrusion. Individual NASS cases were reviewed to gain a deeper understanding of the mechanical particulars in the between-rail crash.

Thoracolumbar spine fractures in frontal impact crashes.
The objective of this investigation was to characterize these injuries using real world crash data from the US-DOT-NHTSA NASS-CDS and CIREN databases. Thoracic and lumbar AIS vertebral body fracture codes were searched for in the two databases. The NASS database was used to characterize population trends as a function of crash year and vehicle model year. The CIREN database was used to examine a case series in more detail. From the NASS database there were 2000-4000 occupants in frontal impacts with thoracic and lumbar vertebral body fractures per crash year. There was an increasing trend in incidence rate of thoracolumbar...

Kinematic Comparison of the Hybrid III and Q-Series Pediatric ATDs to Pediatric Volunteers in Low-Speed Frontal Crashes.
Authors: Seacrist T, Samuels M, García-España JF, Arbogast KB, Mathews EA, Balasubramanian S, Maltese MR, Longhitano D, St Lawrence S Abstract Previous research has suggested that the rigid pediatric ATD spine may not adequately represent the relatively mobile, multi-segmented spine of the child and thus may lead to important differences in the head trajectory of the ATD relative to a human. Recently we compared the responses of size-matched child volunteers to the Hybrid III 6-year-old ATD in low-speed frontal sled tests, illustrating differences in head, spinal, and pelvic kinematics as well as seating...

Homogenization of vehicle fleet frontal crash pulses from 2000-2010.
The objective of this study was to quantify the characteristics of crash pulses for different vehicle types in the contemporary North American fleet, and delineate current trends in crash pulse evolution. NHTSA and Transport Canada crash test databases were queried for full-frontal rigid barrier crash tests of passenger vehicles model year 2000-2010 with impact angle equaling zero degrees. Acceleration-time histories were analyzed for all accelerometers attached to the vehicle structure within the occupant compartment. Custom software calculated the following crash pulse characteristics (CPCs): peak deceleration, time of p...

Costs of alcohol-involved crashes, United States, 2010.
Authors: Zaloshnja E, Miller TR, Blincoe LJ Abstract This paper estimates total and unit costs of alcohol-involved crashes in the U.S. in 2010. With methods from earlier studies, we estimated costs per crash survivor by MAIS, body part, and fracture/dislocation involvement. We multiplied them times 2010 crash incidence estimates from NHTSA data sets, with adjustments for underreporting of crashes and their alcohol involvement. The unit costs are lifetime costs discounted at 3%. To develop medical costs, we combined 2008 Health Care Utilization Program national data for hospitalizations and ED visits of cra...

Identifying the causes of road crashes in Europe.
Authors: Thomas P, Morris A, Talbot R, Fagerlind H Abstract This research applies a recently developed model of accident causation, developed to investigate industrial accidents, to a specially gathered sample of 997 crashes investigated in-depth in 6 countries. Based on the work of Hollnagel the model considers a collision to be a consequence of a breakdown in the interaction between road users, vehicles and the organisation of the traffic environment. 54% of road users experienced interpretation errors while 44% made observation errors and 37% planning errors. In contrast to other studies only 11% of dri...

Alcohol, drugs and driving: implications for evaluating driver impairment.
Authors: Brown T, Milavetz G, Murry DJ Abstract Impaired driving is a significant traffic safety problem, and alcohol and drugs taken before driving contribute substantially to this problem. With the increase in use of prescription medication and the decriminalization of some drugs, it has become increasingly important to understand the manifestation of driver impairment. Building upon previous alcohol research conducted at the National Advanced Driving Simulator (NADS), this study enrolled commercial bus drivers to evaluate the effect of triazolam on driving performance to assess difference between placeb...

Adolescent Balloon Analog Risk Task and Behaviors that Influence Risk of Motor Vehicle Crash Injury.
Authors: Vaca FE, Walthall JM, Ryan S, Moriarty-Daley A, Riera A, Crowley MJ, Mayes LC Abstract Risk-taking propensity is a pivotal facet of motor vehicle crash involvement and subsequent traumatic injury in adolescents. Clinical encounters are important opportunities to identify teens with high risk-taking propensity who may later experience serious injury. Our objective was to compare self-reports of health risk behavior with performance on the Balloon Analog Risk Task (BART), a validated metric of risk-taking propensity, in adolescents during a clinical encounter. 100 adolescent patients from a hospital...

The impact of state level graduated driver licensing programs on rates of passenger restraint use and unlicensed driving in fatal crashes.
The objective of this study was to assess the impact of varying state level GDL programs on rates of unlicensed driving and on passenger restraint use. De-identified data from the National Highway Traffic Safety Administration's Fatality Analysis Reporting System from years 1996-2010 was analyzed. Fatal crashes involving drivers (15-24 yrs) and their passengers (15-24 yrs) were included. Using a validated system, each state's GDL laws at a given month were rated as poor, marginal, fair, or good. The association between GDL strength and unlicensed driving was analyzed graphically and by chi-square test. Multivariate logisti...
