The reconstitution of road traffic accidents scenes is a contemporary and important issue, addressed both by private and public entities in different countries around the world. However, the task of collecting data on site is not generally focused on with the same orientation and relevance. Addressing this type of accident scenario requires a balance between two fundamental yet competing concerns: (1) information collecting, which is a thorough and lengthy process and (2) the need to allow traffic to flow again as quickly as possible. This technical note proposes a novel methodology that aims to support road traffic authorities/professionals in activities involving the collection of data/evidences of motor vehicle collision scenarios by exploring the potential of using low-cost, small-sized and light-weight unmanned aerial vehicles (UAV). A high number of experimental tests and evaluations were conducted in various working conditions and in cooperation with the Portuguese law enforcement authorities responsible for investigating road traffic accidents. The tests allowed for concluding that the proposed method gathers all the conditions to be adopted as a near future approach for reconstituting road traffic accidents and proved to be: faster, more rigorous and safer than the current manual methodologies used not only in Portugal but also in many countries worldwide.

Aim: To determine the relationship between visual status of commercial motor vehicle drivers and road traffic accidents (RTA) in an urban area of Niger Delta, Nigeria. Methods: Four hundred commercial vehicle drivers in the 10 major motor parks of Port Harcourt LGA were interviewed and examined in this study. A structured questionnaire on demographic characteristics, driving and ocular history was administered. Ocular examination included visual acuity, refraction, visual field, tonometry, colour vision test and ophthalmoscopy. The data collected was entered into computer using EPI-INFO statistical software for analysis. Ethical approval was obtained from relevant authorities.   Results: Seven drivers (1.8%) out of 400 drivers examined were visually impaired. There were 14 cases (3.5%) of monocular blindness. Eighteen (4.5%) were colour blind (p>0.05) while 16 (4%) had visual field defects (p>0.05). One hundred and eighty two (45.5%) drivers had been involved in RTA, out of which 2 drivers (1.1%) were visually impaired (p>0.05). Cataract found in 37 cases was the leading cause of visual impairment (42.8%). Other common ocular problems were pterygium (26.7%), presbyopia (22.9%), glaucoma (11.5%), and refractive error (8.4%).There was no statistical significant association between the ocular findings and RTA Conclusion: Only a few of those involved in RTA were actually visually impaired. Therefore, other factors may have been responsible for the majority of the cases of the RTAs in this study necessitating the need for more research.

The aim of this study is to investigate the possible role of placental location on the risk of placental abruption in road traffic accidents involving a pregnant driver. Placental abruption accounts for around 50–70% of fetal deaths in motor vehicle accidents. The computational pregnant occupant model, ‘Expecting’, which has a multi-body fetus and a finite element uterus model was developed at Loughborough University and is used in this investigation. The placenta is located in the upper region of the uterus near the fundus in ‘Expecting’. Four locations for the placenta; anterior, posterior, lateral left, lateral right cases are modelled and used in simulations in this study. These models are used to simulate a range of frontal impacts of severity 15 kph and 30 kph. Three cases of occupant restraint: three-point seatbelt with an airbag, three-point seatbelt only and airbag only conditions are investigated. The maximum strains developed in the uterus and utero-placental interface (UPI) have been estimated and compared for these scenarios in order to investigate placental abruption that leads to fetal loss. Placenta located at anterior position is found to be at higher risk than other positions considered.

Impacts Of Climate Change

The potential costs of road traffic accidents (RTAs) to society are immense. Yet, no study has attempted to examine the impact of climate change on RTAs in Saudi Arabia, though RTA-leading deaths are very high, and the occurrence of climatic events is very frequent. Therefore, this study aims to assess the impact of climate change on RTAs in Saudi Arabia and to recommend some climate change mitigation and adaptation policies to make roads safe for all. This study employed annual data from 13 regions of Saudi Arabia, from 2003 to 2013. The data were analyzed on the basis of panel regression models—fixed effect, random effect, and the pooled ordinary least square. The findings show that temperature, rainfall, sandstorms, and number of vehicles were statistically and significantly responsible for RTAs in Saudi Arabia in the study period. This study also found that RTAs both inside and outside cities significantly caused injuries, but only RTAs inside cities significantly caused death. Furthermore, the death from RTAs injuries was found to be statistically significant only for motor vehicle accidents. The findings will assist policymakers in taking the right courses of action to mitigate the negative impacts of climate change through understanding climate influence on RTAs.

Road Traffic Accidents

Background: In India, the developing economy and growing population simultaneously made a strong impact on increase in motor vehicle population. This increase in motorization has some adverse effects such as increase in road accidents with economic and functional loss. Head injury is the most common cause of mortality in road traffic accidents. The aim of this study was to know the incidence, pattern, mechanism, mode of head injury along with its distribution in relation to site of vault fracture and intracranial hemorrhage.Methods: Total 391 post-mortem cases of head injury were enrolled during study period. The information regarding age, sex, residence, marital status, date and time of time of accident and of death was gathered from police inquest report, relatives, dead body challan and clinical details from hospital records. During autopsy, detailed examination was carried out and data regarding both external and internal injuries were carefully recorded and analyzed.Results: The peak incidence of head injury was observed in the age group of 21-30 years. Most of deceased were from early age group and the male deceased were more than females. Majority victims of head injury were from road Traffic Accidents followed by fall from height, railway accidents and assault. Fissured fracture of vault was found in almost half cases. Subdural and subarachnoid hemorrhage were the most common one we encountered.Conclusions: Head injury due to RTA is well known public health problem causing death and disability. It is required from concerned government authority to take appropriate and immediate measures for reducing the incidence of head injury.

Falling Asleep

A significant proportion of internal transportation of goods is carried out by road. Statistics show that a large number of road traffic accidents, including fatalities, have to do with the driver falling asleep behind the wheel. A method was developed to stop the driver from falling asleep behind the wheel and a device to implement it; as a result, a patent for an invention was obtained. Some experimental studies were realized to implement this method and ensure the functioning of the device. As an example, the results of an experiment with KAMAZ 55102 motor vehicle were quoted, including the measure of the steering wheel angle (αBH = 4,6°) above which it is considered as steering of the wheel operator. In addition to that, the value of the minimum allowable number of steerings of the awake operator in a unit of time was given, and it came up to 0.5 steerings a second. Based on the experimental studies, some theoretical dependences describing the operation of the device preventing the driver from falling asleep at the wheel of a vehicle were developed.

A prospective study of 726 cases of coroner's autopsies carried out over a period of two years (1st January, 1996 − 31st December, 1997) was reviewed. The causes and circumstances of death are defined and classified into natural and unnatural deaths. Fifty cases (6.3%) were children while the remaining 676 cases (93.1%) were adults in a male to female ratio of 2.6 to 1. The most common indications for coroner's autopsies were sudden unnatural deaths (SUDs) accounting for 485 cases (66.8%) and also sudden unexpected natural deaths (SUNDs) (241 cases) accounting for 33.2%. In the first category, road traffic accidents accounted for 86.7% of cases with deaths involving motor vehicle drivers and their passengers (41.8%); pedestrians (37.1%); and motorcyclists and their passengers (18.6%). The commonest causes of death in all road traffic accidents were craniocerebral injuries and haemorrhagic shock. In the second category the most common causes of sudden unexpected natural death were cardiovascular diseases resulting from complications of hypertension (54.7%) occurring in apparently healthy individuals. Other causes of death were pneumonia, pulmonary tuberculosis, typhoid fever and neoplastic diseases. This study showed that in Nigeria, with an increasing acquisition of dietary and life style habits of the developed western world, there is becoming a concomitant risk of deaths from road traffic accidents and sudden unexpected natural deaths from hypertensive cardiovascular disease.
