[Show abstract][Hide abstract] ABSTRACT: A total of recent 187 passenger car-adult pedestrian cases, occurred in Chongqing, China, with 81 severe injuries and 106 deaths, were analysed. The AIS distributions in the head, thorax and abdomen were associated with the severe injuries and deaths, but not in the extremities. The mean ISS of the severe injuries and deaths was 26.3 ± 17.0 and 35.5 ± 17.0. For the severe injuries, 2% occurred at the impact speeds of over 70 km/h and none of the fatal accidents occurred at the impact speeds of lower than 30 km/h. Pedestrians aged over 46 years old and sustaining head injuries have a high fatality rate. The accidents with the impact speeds of over 40 km/h occurring in highways and sunny days carried a high fatal risk. The findings proposed the characteristics of vehicle-pedestrian accidents in Chongqing, China, representing some regional levels in some developing countries.

[Show abstract][Hide abstract] ABSTRACT: To study the characteristics of fatal vehicle-pedestrian accidents in China，a team was established and passenger car-pedestrian crash cases occurring between 2006 and 2011 in Beijing and Chongqing, China were collected. A total of 121 fatal passenger car-adult pedestrian collisions were sampled and analyzed. The pedestrian injuries were scored according to Abbreviated Injury Scale (AIS) and Injury Severity Score (ISS). The demographical distributions of fatal pedestrian accidents differed from other pedestrian accidents. Among the victims, no significant discrepancy in the distribution of ISS and AIS in head, thorax, abdomen, and extremities by pedestrian age was found, while pedestrian behaviors prior to the crashes may affect the ISS. The distributions of AIS in head, thorax, and abdomen among the fatalities did not show any association with impact speeds or vehicle types, whereas there was a strong relationship between the ISS and impact speeds. Whether pedestrians died in the accident field or not was not associated with the ISS or AIS. The present results may be useful for not only forensic experts but also vehicle safety researchers. More investigations regarding fatal pedestrian accidents need be conducted in great detail.

[Show abstract][Hide abstract] ABSTRACT: Objective:
To analyze the injuries of motorcyclists involved in fatal motorcycle frontal crashes.
A survey group involving multi-discipline experts was built to randomly collect data on fatal motorcycle frontal collision accidents that occurred in Chongqing during 2006-2010. The sampled information included medical or autopsy reports, blood alcohol concentration (BAC) level, helmet use, accident witness, field sketch as well as field photos. The motorcyclist injuries were scored according to the Abbreviated Injury Scale (AIS) 2005. The involved riders with a BAC level larger than or equal to 20 mg/ml were attributed to alcohol use. Data were processed statistically with nonparametric test via software SPSS 11.0.
A total of 86 fatal motorcycle frontal crashes were sampled and further analyzed. The age of motorcyclists enrolled in this investigation showed nominal distribution and the middle-aged (30-39 years) occupied the highest percentage of fatalities. There were only 14 motorcyclists (16.3%) wearing helmets at the moment of collision. And 12.8% of these motorcyclist crashes were attributable to alcohol use. Impact injury was the main fatal cause, accounting for 72% of motorcyclist deaths, followed by tumbling injury (26%) and run-over (2%). Respectively 84%, 22% and 19% of motorcyclists who sustained head, chest and abdominal trauma died. Extremity injury was the most frequently observed injury type.
This investigation is helpful to build accident prevention programs and develop protection devices which may effectively mitigate injuries and prevent deaths following motorcycle frontal collision accidents. Further investigations on motorcycle collision accidents are still needed.
