Accident; analysis and prevention

Previous studies have suggested that motor vehicle occupants seated on the near-side of a lateral impact have a higher proportion of thoracoabdominal injuries. However, due to limitations in previous studies, the true association between seat position, side of lateral impact, and thoracoabdominal injury is unclear. ⋯ There is a strong, synergistic relationship between seat position and side of lateral MVC in assessing risk of serious thoracic and abdominal injury among adult occupants. The probability of serious thoracoabdominal injury increases with increasing proximity of seat position to side of the crash and the risk of thoracic injury is higher than abdominal injury for all seat positions.

The American Academy of Pediatrics and the American Medical Association recommend storing firearms unloaded and locked up to minimize the chance of injury. Although these recommendations appeal to common sense, no study has yet addressed whether firearm storage practices influence the risk of unintentional firearm injury. ⋯ Our findings provide empirical support for recommendations issued by the AMA and the AAP that firearms should be stored unloaded and locked, and suggest that promoting safer storage practices could save many lives.

In nonfatal passenger vehicle-pedestrian accidents, the lower extremities are the most commonly injured body parts. The European Enhanced Vehicle-safety Committee Working Group 17 (EEVC/WG17) pedestrian subsystem test method using a legform impactor has been developed mainly for evaluation of aggressiveness of the front bumper of passenger vehicles. However, in recent years the number of sports utility vehicles (SUV) with a high bumper has been rapidly increasing. ⋯ The results indicate that the type of injury, i.e., to the tibia and knee ligament, could become an injury to the femur with an increase in bumper height. Furthermore, the main injury at an impact velocity of around 20-30km/h is to the knee ligament. On the other hand, the main injury at an impact velocity of around 40km/h is a fracture of the lower extremities.

This study analyzes vehicle-pedestrian crashes at intersections in Florida over 4 years, 1999-2002. The study identifies the group of drivers and pedestrians, and traffic and environmental characteristics that are correlated with high pedestrian crashes using log-linear models. The study also estimates the likelihood of pedestrian injury severity when pedestrians are involved in crashes using an ordered probit model. ⋯ As a result of the analysis, it was found that pedestrian and driver demographic factors, and road geometric, traffic and environment conditions are closely related to the frequency and injury severity of pedestrian crashes. Higher average traffic volume at intersections increases the number of pedestrian crashes; however, the rate of increase is steeper at lower values of average traffic volume. Based on the findings in the analysis, some countermeasures are recommended to improve pedestrian safety.
