“…For this purpose, sets of random numbers were generated, representing the classic 6 C i measurements (Tumbas and Smith, 1988) of crush depth utilised in the Campbell method; the difference between the energy loss calculated starting from the C i measurements and on the linearized profile was then evaluated.

“…The latter is subdivided in six parts (C1-C6), where the dimension of the damage is quantified (CRASH3 method) [22,23]. In order to describe the nature and the location of the direct contact on the vehicle in car and van accidents the Collision Deformation Classification (CDC) [24] is used.…”

BackgroundIn the metropolitan area of Florence, 62% of major traumas involve powered two wheeler rider and pillion passengers, 10% cyclists, and 7% pedestrians. The urban and extra-urban areas are the most dangerous for the vulnerable road user. In-depth investigations are needed for assessing detailed information on road accidents. This type of study has been very limited in time frame in Italy, and completely absent in the Tuscan region.Consequently a study called “In-depth Study of road Accident in FlorencE” (In-SAFE) has been initiated.MethodsA network between the Department of Mechanics and Industrial Technologies (University of Florence) and the Intensive Care Unit of the Emergency Department (Careggi Teaching Hospital, Florence) was created with the aim of collecting information about the road accidents. The data collected includes: on-scene data, data coming from examination of the vehicles, kinematics and dynamic crash data, injuries, treatment, and injury mechanisms. Each injury is codified thorough the AIS score, localized by a three-dimensional human body model based on computer tomography slices, and the main scores are calculated. We then associate each injury with its cause and crash technical parameters. Finally, all the information is collected in the In-SAFE database.ResultsPatient mean age at the time of the accident was 34.6 years, and 80% were males. The ISS mean is 24.2 (SD 8.7) and the NISS mean is 33.6 (SD 10.5). The main road accident configurations are the “car-to-PTW” (25%) and “pedestrian run over” (17,9%). For the former, the main collision configuration is “head-on crash” (57%). Cyclists and PTW riders-and-pillions-passengers suffer serious injuries (AIS3+) mainly to the head and the thorax. The head (56.4%) and the lower extremities (12.7%) are the most frequently injured pedestrian body regions.ConclusionsThe aim of the project is to create an in-depth road accident study with special focus on the correlation between technical parameters and injuries. An in-depth investigation team was setup and is currently active in the metropolitan area of Florence.Twenty-eight serious road accidents involving twenty-nine ICU patients are studied. PTW users, cyclist and pedestrians are the most frequently involved in metropolitan accidents.

“…Adjusting the analyses of the effectiveness of restraints for barrier equivalent velocity addresses the issue of different car safety features and the severity of a crash 17 – 19. Barrier equivalent velocity was available only in the later years of the study and, because of limited resources, was performed on only a single vehicle in each crash.…”

Objective To study effectiveness of seat belts for protecting school age children in road vehicle crashes. Design Crash examinations by trained investigators. Setting Ten Canadian university based crash investigation centres. Subjects 470 children aged 4-14 years, with 168 selected for detailed analysis, and 1301 adults. Main outcomes measures Use of seat belts by vehicle occupants; severity of injury adjusted for age and crash severity. Results Overall, 40% (189/470) of children were unbelted. Of the 335 children in cars driven by belted adults, 73 (22%) were unbelted. The odds of sustaining fatal or moderately severe injury (injury severity score >4) for children in the front passenger seat was more than nine times higher for unbelted children than for belted ones (odds ratio 9.8 (95% confidence interval 2.4 to 39.4)) and for those in the rear left seat was more than two times higher for unbelted than for belted children (2.6 (1.1 to 5.9)). The protection afforded by seat belts compared favourably with the results for adults in the same seat positions (odds ratios for unbelted v belted adults of 2.4 and 2.7 for front and rear seat passengers respectively). Conclusions Seat belts helped to protect school age children from injury in road vehicle crashes. However, 40% of children were unbelted. Despite standard seat belts being designed for adults, school age children were at least as well protected as adults.
