The part that children play in traffic accidents has been studied by numerous workers from differing points of view. Slätis,1 in a study of 5,291 persons injured in traffic accidents and receiving medical treatment in Sweden, found that 16.3% were less than 15 years of age. An examination by Mackay2 of a series of 250 accidents investigated at the scene in Birmingham, England, found that children less than 16 years of age formed 6.2% of the 464 persons involved. In Brisbane, Australia, Jamieson and Tait3 found that children less than 15 years old formed 10.9% of a group of 1,000 admissions or deaths from traffic accidents. Gädeke4 in Germany, found children less than 15 years old were injured more often in rural accidents, that traffic accidents formed 35 to 40% of all fatal accidents in children, and that injuries to the head and lower limb were most common. In Sweden, Ekström, et al.5 found that the majority of children involved in accidents they studied were pedestrians or pedal cyclists, and 40% were between 5 and 9 years old. Moore and Lilienfeld6 reported on 31,001 occupants of known age in 14,520 automobiles involved in injury-producing accidents on rural highways in the United States. They found that children less than 12 years of age formed 9%, adolescents age 12 to 18 years formed 16%, and adults of more than 18 years formed 75%. They found that children received fewer and less severe injuries than adolescents or adults, in each seating position. Front seat passengers in each age group were injured more often and more severely than rear seat passengers.

Seat Belt Use

Using seat belts reduces traffic injuries and fatalities. Passengers in the rear seat typically use their seat belts less often than drivers or front-seat passengers. Seat belt use in the back is even less frequent in vehicles for hire such as taxi cabs and rideshare vehicles than in private passenger vehicles. This observational study of adult passengers video-recorded in rideshare vehicles in San Francisco found that a sign mounted at rear passenger seated eye level, and that warned of the risks of failing to wear a seat belt, resulted in significantly higher rates of seat belt use than for rear seat passengers not exposed to the warning sign. Results also showed that age, gender, and trip duration did not have a significant effect on rear seat belt use. Implications for future research and other countermeasures are discussed.

AbstractWe performed a retrospective study of the injuries and characteristics of occupant fatalities in motor vehicle collisions in southeast Norway. The goal was to provide updated knowledge of injuries sustained in modern vehicles and detect possible differences in injury pattern between drivers and passengers. Forensic autopsy reports, police, and collision investigation reports from 2000 to 2014 were studied, data extracted and analyzed.A total of 284 drivers, 80 front-seat passengers, and 37 rear-seat passengers were included, of which 67.3% died in front collisions, 13.7% in near-side impacts, 13.5% in rollovers and 5.5% in other/combined collisions. Overall, 80.5% died within one hour after the crash. The presence of fatal injuries to the head, neck, thorax and abdomen were observed in 63.6%, 10.7%, 61.6% and 27.4% respectively. All occupants with severe injuries to the head or neck had signs of direct impact with contact point injuries to the skin or skull. Injuries to the heart and spleen were less common in front-seat passengers compared to drivers. Seat belt abrasions were more common and lower extremity fractures less common in both front-seat and rear-seat passengers compared to drivers. Blood alcohol and/or drug concentrations suggestive of impairment were present in 30% of all occupants, with alcohol more often detected among front-seat passengers compared to drivers.Few driver-specific and passenger-specific patterns of injury could be identified. When attempting to assess an occupant’s seating position within a vehicle, autopsy findings should be interpreted with caution and only in conjunction with documentation from the crash scene.

Rear Impacts

Since 1996 the NHTSA has warned of the airbag deployment injury risk to front seated children and infants, during frontal impact, and they have recommended that children be placed in the rear seating areas of motor vehicles. However, during most rear impacts the adult occupied front seats will collapse into the rear occupant area and, as such, pose another potentially serious injury risk to the rear seated children and infants who are located on rear seats that are not likely to collapse. Also, in the case of higher speed rear impacts, intrusion of the occupant compartment may cause the child to be shoved forward into the rearward collapsing front seat occupant thereby increasing impact forces to the trapped child. This study summarizes the results of more than a dozen actual accident cases involving over 2-dozen rear-seated children, where 7 children received fatal injuries, and the others received injuries ranging from severely disabling to minor injury. Types of injuries include, among others: crushed skulls and brain damage; ruptured hearts; broken and bruised legs; and death by post-crash fires when the children became entrapped behind collapsed front seat systems. Several rear-impact crash tests, utilizing sled-bucks and vehicle-to-vehicle tests, are used to examine the effects of front seat strength and various types of child restraint systems, such as booster seats and child restraint seats (both forward and rearward facing), in relation to injury potential of rear seated children and infants. The tests utilized sedan and minivan type vehicles that were subjected to speed changes ranging from about 20 to 50 kph (12 to 30 mph), with an average G level per speed change of about 9 to 15. The results indicate that children and infants seated behind a collapsing driver seat, even in low severity rear impacts of less than 25 kph, encounter a high risk of serious or fatal injury, whether or not rear intrusion takes place. Children seated in other rear seat positions away from significant front seat collapse, such as behind the stronger “belt-integrated” types of front seats or rearward but in between occupied collapsing front seat positions, are less likely to be as seriously injured.

Seat Belt Use

AbstractIntroduction:Trauma is a major cause of death and disability worldwide. A quarter of all fatalities due to injury occur due to road traffic crashes with 90% of the fatalities occurring in low- and medium-income countries. Poor compliance with the use of seat belts is a problem in many developing countries. The aim of this study was to evaluate the level of seatbelt compliance in motor vehicles in Benin City, Nigeria.Methods:A five-day, observational study was conducted in strategic locations in Benin City. The compliance rates of drivers, front seat passengers, and rear seat passengers in the various categories of vehicles were evaluated, and the data were subjected to statistical processing using the Program for Epidemiology.Results:A total of 369 vehicles were observed. This consisted of 172 private cars, 64 taxis, 114 buses, 15 trucks, and four other vehicles. The seat belt compliance rate for drivers was 52.3%, front seat passengers 18.4%, and rear seat passengers 6.1%. Drivers of all categories of vehicles were more likely to use the seat belt compared to front seat passengers (p = 0.000) and rear seat passengers (p = 0.000). Drivers of private cars were more likely to use seat belts compared to taxi drivers (p = 0.000) and bus drivers (p = 0.000). Front seat passengers in private cars were more likely to use the seat belt compared to front seat passengers in taxis (p = 0.000) and buses (p = 0.000). Rear seat pas-sengers in private cars also were more likely to use seat belts compared to rear seat passengers in taxis (p = 0.000) and buses (p = 0.000).Conclusions:Compliance with seat belt use in Benin City is low. Legislation, educational campaigns, and enforcement of seat belt use are needed.

Front Crash

To study the injury index to driver in front crash, this article uses the MADYMO software to establish the driver constraint system model which including car bodies, safety belts and 50% dummy for impact simulation. The simulation values are close to test ones after contrasted with the vehicle impact test. The influence of design parameters including the D-ring friction coefficient of seat belt, airbag strap and steering column on driver HIC, T3MS, THPC are researched by this model. The results show that: The smaller D-ring friction and a longer airbag strap length and steering column crushing can effectively improve the driver safety.
