Comparative StudyFifteen-passenger vans and other transportation options: a comparison of driver, vehicle, and crash characteristics.
Fifteen-passenger vans (15-PVs) are a convenient and economical way to transport small groups of people and many educational, community, and health organizations utilize them. Given recent tragic crashes involving 15-PVs, many organizations are reconsidering their use. The goal of this study was to examine driver, vehicle, and crash characteristics of fatal 15-PV collisions over the past 2 decades in comparison to 3 other common vehicle classes. ⋯ Drivers need to be aware that as occupancy rates of the vehicles they drive rise so does the risk of rollover and fatalities, especially among minivans and 15-PVs. Organizations transporting groups need to balance cost and safety management by selecting vehicle types and drivers with acute awareness of the risks involved.

To assess the blood alcohol concentration (BAC; dependent variable) of patients with road traffic injuries (RTIs) presenting at 3 provincial and central hospitals in the Socialist Republic of Viet Nam by age, sex, and road user type (independent variables). This survey formed part of the Viet Nam Road Traffic Injury Prevention Project, funded by Bloomberg Philanthropies. ⋯ The results of this preliminary study indicate that 29.1 percent of all car drivers and motorcycle riders presenting at hospitals with RTIs exceeded the legal BAC limit for operating a motor vehicle. Though further study is required, this is suggestive that strengthening the enforcement of drink-driving laws is an urgent national road safety priority.

Scooter crashes at university: intervention tactics for modified behavior and helmet use.
Mopeds and scooters are defined as 2-wheeled vehicles with engine displacement ranging from 49 to 250 cm(3). These vehicles have experienced a resurgence in modern culture and are especially popular on large university campuses. Increased operation of mopeds and scooters has been a contributor to increased accidents and in some cases fatalities. Available statistics indicate that a majority of individuals involved in scooter crashes were not wearing helmets. The objective of this study was to explore perceptions of helmets and the significance of behavioral intention related to attitude toward helmet use among operators of these potentially dangerous motor vehicles. ⋯ University students who operated scooters were principally untrained in safe operation measures and in many cases ignored traffic laws. Though perceptions of helmets as a safety device were significant, they were viewed as uncomfortable, most often among female operators. Key psychological indicators of attitudes toward helmet use were perceived norms and control in making choices. The best course of action is messages that (1) introduces modern features that make helmets more user adaptable to comfort; (2) promote a positive outcome through users' motivation to comply to norms (i.e., parental influence); and (3) encourage the perceived empowerment that emanates from control in decision making.

Importance of muscle activations for biofidelic pediatric neck response in computational models.
During dynamic injury scenarios, such as motor vehicle crashes, neck biomechanics contribute to head excursion and acceleration, influencing head injuries. One important tool in understanding head and neck dynamics is computational modeling. However, realistic and stable muscle activations for major muscles are required to realize meaningful kinematic responses. The objective was to determine cervical muscle activation states for 6-year-old, 10-year-old, and adult 50th percentile male computational head and neck models. Currently, pediatric models including muscle activations are unable to maintain the head in an equilibrium position, forcing models to begin from nonphysiologic conditions. Recent work has realized a stationary initial geometry and cervical muscle activations by first optimizing responses against gravity. Accordingly, our goal was to apply these methods to Duke University's head-neck model validated using living muscle response and pediatric cadaveric data. ⋯ Though muscular loads were not large enough to cause vertebral compressive failure, they would provide a prestressed state that could protect the vertebrae during tensile loading but might exacerbate risk during compressive loading. For example, in the 10-year-old, a load of 602 N was produced, though estimated compressive failure tolerance is only 2.8 kN. Including muscles and time-variant activation schemes is vital for producing biofidelic models because both vary by age. The pediatric activations developed represent physiologically appropriate sets of initial conditions and are based on validated adult cadaveric data.

Feasibility of a computer-delivered driver safety behavior screening and intervention program initiated during an emergency department visit.
Injuries from motor vehicle crashes are a significant public health problem. The emergency department (ED) provides a setting that may be used to screen for behaviors that increase risk for motor vehicle crashes and provide brief interventions to people who might otherwise not have access to screening and intervention. The purpose of the present study was to (1) assess the feasibility of using a computer-assisted screening program to educate ED patients about risky driving behaviors, (2) evaluate patient acceptance of the computer-based traffic safety educational intervention during an ED visit, and (3) assess postintervention changes in risky driving behaviors. ⋯ Overall, patients were very satisfied receiving educational information about these behaviors via computer during their ED visits and found the program easy to use. We found a high prevalence of self-reported risky driving behaviors in our ED population. At 1-month follow-up, patients reported a significant decrease in these behaviors. This study indicates that a low-intensity, computer-based educational intervention during an ED visit may be a useful approach to educate patients about safe driving behaviors and safe drinking limits and help promote behavior change.
