Road traffic crashes with fatal and non-fatal injuries in Arkhangelsk,Russia in 2005–2010

The study investigated trends in traffic crashes with fatal and non-fatal injuries in Arkhangelsk, Russia in 2005–2010. Data were obtained from the road police. Negative binomial regression with time regressor was used to investigate trends in monthly incidence rates (IRs) of crashes, fatalities, and non-fatal injuries. During the six-year period, the police registered 4955 crashes with fatal and non-fatal injuries, which resulted in 217 fatalities and 5964 non-fatal injury cases. The IR of crashes with fatal and non-fatal injuries per total population showed no evident change, while the IR per increasing total number of motor vehicles decreased on average by 0.6% per month. Pedestrian crashes constituted 51.8% of studied crashes, and pedestrians constituted 54.6% of fatalities and 44.5% of non-fatal injuries. The IRs of pedestrian crashes and non-fatal pedestrian injuries per total population decreased on average by 0.3% per month, and these were the major trends in the data.     

Driver education: how effective?

Abstract

In the early 20th century, the numbers of motor vehicles in use grew rapidly in the USA, Canada, and many European countries. By the 1930s, the number of automobile crashes and the resulting deaths and injuries was a significant problem and various safety organizations tried to address it with education and publicity programs aimed at changing driver behaviour. It is not clear when the high crash risks of young drivers were first identified, but in the early 1930s driver education courses began to be offered in US high schools (feasible because US licensing ages were 16 or younger) and soon such courses were being touted (with no evidence) as ‘the most obvious way’ to reduce traffic crashes. Over the years many claims were made for the effectiveness of high school driver education, however, it was not until the late 1960s that competent research studies (including randomized control trials) were undertaken. The consistent findings from these studies have been that high school driver education does not reduce crashes. Furthermore, the trained students get their licenses sooner, and because teenagers have very high crash risks, the net result of high school driver education is increased numbers of crashes.     

Area-based differences in injury risks in a small Swedish municipality – Geographic and social differences

The current study investigates the geographic and social differences in injury risks across living areas in a small semi-urban Swedish municipality. The study population consisted of all people living in the municipality during the years 1992–1996 (31,820, December 1996). Area comparisons were made based on data related to the municipality’s 15 census districts and grouped according to the geographic location and three different social characteristics (proportion of unemployed, of low educated, or of people born outside Sweden). Injury data was gathered for the period 1992–1996 from two data sources: Sweden’s National Hospital Discharge Register, and the local outpatient register. Three diagnosis groups were used: all injuries aggregated, traffic injuries and other unintentional injuries. Odds-ratios were calculated for males and females separately. There were no remarkable differences in injury risks between areas, whether compared on the basis of their geographic location or some of their socio-economic characteristics. These findings could be attributed to either a lack of sensitivity of the measures employed or the existence of a well-functioning safety promotion program in the municipality that impacts on injury risk distribution between areas. This, in turn, does not imply that members of underprivileged social groups are not in need of special support regardless of the area to which they belong.

Poisonings

Manufacturers of household products – including appliances, exercise equipment, and even some children's toys – expect consumers to supervise their children to prevent product related injuries. This approach to hazard prevention places the burden of safety on parents and caretakers. This study examined actual supervision practices of parents of children between the ages of two and six years. 59 parents, aged 31 to 40 years, residing in Montgomery County, Maryland, completed a 24-item self-administered questionnaire, consisting of multiple choice and open-ended questions. Nearly all respondents reported that there are times when their children are in a different room from them. When the children are out of sight, parents reported checking on their children periodically, with increasingly longer periods between observations, as the child gets older. Nearly half of the children got out of bed in the morning always or often before a parent. Ninety-five percent of parents perceived that their child was at no risk or slight risk of injury when getting up in the morning before them. In conclusion, it can be said that many parents supervise their children by being close-by and on-hand as needed, rather than being directly involved in the child's activities. Manufacturers are encouraged to employ passive measures and sound designs, rather than rely on close parental supervision for injury prevention.     

Data mining in road crash analysis: the context of developing countries

The recent advancements in the field of data mining have made vast progress in extracting new information and hidden patterns from large datasets which are often overlooked by the traditional statistical approaches. These methods focus on searching for new and interesting hypothesis which were previously unobserved. Road safety researchers working with the crash data from developed world have seen encouraging success in obtaining new insight into crash mechanism through data mining. An attempt was made in this study to apply these advance methods and evaluate their performance in manifesting crash causes for Bangladesh. The study applies hierarchical clustering to identify hazardous clusters, random forest to find important variables explaining each of these clusters, and classification and regression trees to unveil their respective crash mechanisms for the road crash data of Bangladesh. The results identified several new interesting relationships and acknowledged issues related to quality of data.     

Child motor vehicle occupant and pedestrian casualties before and after enactment of Child Restraint Seats Legislation in Japan

Problem. Prevention of injuries to child passengers is a significant public health priority, as motor vehicle-related injuries remain a leading cause of death for children in Japan. The purpose of compulsory child restraint seats legislation in April 2000 was to reduce the number of child passengers killed or injured in motor vehicle crashes.

Methods. The objectives of this preliminary evaluation are to measure the effectiveness, benefits and usage of safety seats for child passengers aged 1–5 years by analysing the child casualty data for the period of 1997–2002. Population and vehicle miles travelled based injury and fatality rates were used to compare before and after legislation trends in child casualties.

Results. Despite overall increases in the use of child restraint seats (as observed by different national surveys), overall casualty rates in motor vehicle occupants in the 1–5 year age group did not change (fatalities and serious injuries) or even increased (minor injuries).

Conclusions. Casualties among restrained children have not decreased since the law came to effect in the year 2000, perhaps because of incorrect usage of the seats. Given that exposure to crash environments is increasing, traffic safety advocates and public health community need to be aware of the importance of child restraints as a means of reducing the likelihood of injury. It is necessary to implement effective community-based child safety seat campaigns to disseminate the information on appropriate restraint use and to increase efforts to enforce the existing legislation.     

Cost analysis of road traffic crashes in China

Abstract

Fatalities and injuries resulting from road traffic crashes is always a serious problem. The overall economic losses caused by road traffic crashes are beyond imagination. Including the economic cost of property damage, productivity loss, medical cost, travel delay time cost, legal cost and insurance cost, the total economic cost of traffic crashes in China in 2017 is calculated as 490.1 billion yuan (72.6 billion USD 2017), which is equivalent to 0.60% of the GDP. The cost of productivity loss accounts for the highest proportion of total economic cost, which is 72%. The second is the travel delay cost, accounting for 12% insurance cost, property damage cost and medical cost are followed. The more serious the injury, the higher the unit economic cost. The unit cost of a crash that caused only property damage is 11,274 yuan. The unit cost of a minor injured crash is 20,223 yuan. The highest unit economic cost is the unit cost of a fatal crash, which is 3,181,394 yuan. This study provides important insights into the cost-benefit analysis of China's road safety policies.

A Multi-Agent View of Strategic Planning Using Group Support Systems and Artificial Intelligence

The strategic planning process is dynamic and complex. Including a Group Support System (GSS) in the problem-solving process can improve the content quality of the strategic plan by allowing increased participation by more members of the organization. However, it can also add to the complexity of the problem by increasing the quantity of textual information that can result from group activity. Added complexity increases cognitive overload and frustrations of those participants negotiating the contents of the strategic plan. This article takes a multi-agent view of the strategic planning process. It considers group participants as multiple agents concerned with the content quality of the strategic plan. The facilitator agent is responsible for guiding groups in the strategic plan construction process as well as for solving process problems such as cognitive overload. We introduce an AI Concept Categorizer agent, a software tool that supports the facilitator in addressing the process problem of cognitive overload associated with convergent group activities by synthesizing group textual output into conceptual clusters. The implementation of this tool reduces frustrations which groups encounter in the process of classifying textual output and provides more time for discussion of the concepts themselves. Because of the large amount of convergent activity necessary for strategic planning, the addition of the AI Concept Categorizer to the strategic planning process should increase the quality of the strategic plan and the buy-in of the participants in the strategic planning process.
