The Impact

Background. Around the world, drug-related road traffic accidents are one of the leading causes of injury and death among road users. Traffic safety is a system that includes the following components: a person – a person's health condition – the use of dangerous drugs of different classification and legal groups – adverse drug reactions – a vehicle – a road. The share of road traffic accidents under the influence of drugs is more than 75 %, they are also the most socially dangerous, because they have grave consequences, cause irreparable harm to the health and death of the victims. The purpose of the study was to analyze the achievements of forensic and pharmaceutical researches in Ukraine on the impact of drugs on the safety, life and health of road users within the framework of the organization of pharmaceutical business, drug technology, pharmaceutical and medical law in a retrospective aspect. Materials and methods. The materials of the imperative research were legislative, regulatory and legal documents; materials of the formation of the scientific school of forensic pharmacy; scientific publications on the topic of the article; Internet resources, sources of scientific literature. To achieve the set goals, the methods of forensic and pharmaceutical, regulatory, documentary, bibliographic, comparative, historical and graphic analysis were used. Results. The experience of the countries of the world in the prophylaxis and prevention of road traffic accidents under the influence of drugs was analyzed. The causes and conditions for the occurrence and consequences of road traffic accidents are multifactorial in nature and are associated with the victims (driver - pedestrian), vehicle, road conditions, and the use of psychoactive drugs. A system of organizational, regulatory and preventive measures has been developed to provide first medical aid to victims of a road traffic accident. Shown that there is a need for scientifically grounded organizational and legal, clinical and pharmacological, forensic pharmaceutical and socio-economic studies on causal relationships between adverse reactions due to the use of drugs of various classification and legal groups, traffic safety and road traffic accidents. For the first time in Ukraine, a mathematical model was proposed to establish the effect of psychoactive drugs on the driver's condition when driving a vehicle, depending on the calculation of the stopping path of the car in accordance with the selected speed and a decrease in the driver's response. The structure of road traffic accidents under the influence of psychoactive drugs has been investigated. Conclusions. A classification of first-aid kits for providing first medical aid to victims of road traffic accidents was proposed, which made it possible to substantiate the need to improve them both in qualitative and quantitative composition, depending on the type of vehicle and the likelihood of an accident with serious consequences. Recommendations were proposed for providing information on the possibility of obtaining medical care and the signal-calling system on the roads, marking the packages of psychoactive drugs with a special mark in the form of a red triangle. The need for further forensic pharmaceutical research has been proven.

The Relationship

The main purpose of this study was to identify and analyze the prevailing types of accidents at roundabouts. The relationship was revealed between certain types of accidents, the place of their occurrence, and the configuration of the roundabout. The study analyzed 321 accidents at 19 ring intersections. Four predominant crash types were identified: rear-end collision, collision with vulnerable road users, side swipe collision, and entering circulate collision. The greatest number of accidents occurred at the weaving lane and at the entrances and exits of the roundabout. Dividing the ring intersections into separate sections to determine the location of the accident allows drawing conclusions on the nature of road traffic accidents and the impact of the roundabout design on safety.

AbstractThe steady increase in the number of road users and their growing mobility mean that the issue of road safety is still a topical one. Analyses of factors influencing the number of road traffic accidents contribute to the improvement of road safety. Because changes in traffic volume follow a daily rhythm, hour of the day is an important factor affecting the number of crashes. The present article identifies selected mathematical models which can be used to describe the number of road traffic accidents as a function of the time of their occurrence during the day. The study of the seasonality of the number of accidents in particular hours was assessed. The distributions of the number of accidents in each hour were compared using the Kruskal-Wallis and Kolmogorov-Smirnov tests. Multidimensional scaling was used to present the found similarities and differences. Similar hours were grouped into clusters, which were used in further analysis to construct the ARMAXmodel and the Holt-Winters model. Finally, the predictive capabilities of each model were assessed.

AbstractCOVID-19 has affected every sector of our society, among which human mobility is taking a dramatic change due to quarantine and social distancing. We investigate the impact of the pandemic and subsequent mobility changes on road traffic safety. Using traffic accident data from the city of Los Angeles and New York City, we find that the impact is not merely a blunt reduction in traffic and accidents; rather, (1) the proportion of accidents unexpectedly increases for “Hispanic” and “Male” groups; (2) the “hot spots” of accidents have shifted in both time and space and are likely moved from higher-income areas (e.g., Hollywood and Lower Manhattan) to lower-income areas (e.g., southern LA and southern Brooklyn); (3) the severity level of accidents decreases with the number of accidents regardless of transportation modes. Understanding those variations of traffic accidents not only sheds a light on the heterogeneous impact of COVID-19 across demographic and geographic factors, but also helps policymakers and planners design more effective safety policies and interventions during critical conditions such as the pandemic.

The Impact

A constantly increasing number of deaths on roads forces analysts to search for models that predict the driver’s propensity for road traffic accidents (RTAs). This paper aims to examine a relationship between the speed and space assessment capabilities of drivers in terms of their association with the occurrence of RTAs. The method used for this purpose is based on the implementation of the interval Type-2 Fuzzy Inference System (T2FIS). The inputs to the first T2FIS relate to the speed assessment capabilities of drivers. These capabilities were measured in the experiment with 178 young drivers, with test speeds of 30, 50, and 70 km/h. The participants assessed the aforementioned speed values from four different observation positions in the driving simulator. On the other hand, the inputs of the second T2FIS are space assessment capabilities. The same group of drivers took two types of space assessment tests—2D and 3D. The third considered T2FIS sublimates of all previously mentioned inputs in one model. The output in all three T2FIS structures is the number of RTAs experienced by a driver. By testing three proposed T2FISs on the empirical data, the result of the research indicates that the space assessment characteristics better explain participation in RTAs compared to the speed assessment capabilities. The results obtained are further confirmed by implementing a multiple regression analysis.

The Impact

Road traffic accident is an accident on a public road in which at least one moving vehicle has been involved and material damage or injury or death has occurred. Traffic accidents occur for various reasons, with one of them being the transport infrastructure and next the condition of traffic environment. Motorways are considered to be the safest roads, which have initially been planned as dedicated roads intended to be travelled only by personal cars, but the evolution of modal split of freight transport in Europe is causing the heterogeneity of traffic flows on these roads, which consequently affects the traffic safety. The aim of this paper is to explore the effects of changing volume and structure of traffic flows on road safety on Slovenian motorways. After the exhaustive analysis of past data, the paper provides different models for forecasting traffic safety on Slovenian motorways.

The Impact

Children pedestrians represent road users with some specifics because of which it is important to study and take into account their traffic behaviour when traffic infrastructure is designed. Design should ensure and enhance their traffic safety because for decades, traffic accidents have been among the first few causes of children and adolescent mortality. Pedestrian speed is one of the important inputs when pedestrian infrastructure, especially crosswalks, is designed. On corridors where children are expected on a daily basis as independent pedestrians, the infrastructure should be adjusted to their characteristics and needs. The results of a study conducted in two Croatian cities of a similar size but of different urban and traffic conditions are presented in this paper. This study aimed at establishing and analysing children’s pedestrian speed while crossing the signalized crosswalk in the buffer area of elementary schools, mostly on primary roads in the school vicinity. Children aged 5–15 were observed, and accordingly V15, V50, and V85 speeds were established on the basis of altogether 600 measurements. Speed was established for children walking individually, in a group and supervised by adults, and of a different age, and based on their gender, the impact of infrastructural elements on their speed in traffic was also analysed. Significant differences were found between children’s speed measured in similar conditions in analysed cities and between some of the analysed groups. This fact proves that when improving conditions for children’s independent movement, it is important to consider their specifics in order to ensure safe design adjusted to children’s needs and limitations. As design speed in this paper, 15 percentile speed (V15) is considered. Suggestions on how to establish children pedestrian speed for design of routes regularly used by school children are proposed as well as some inputs elicited from the study done in Croatia are presented.

The Impact

Background: Road traffic accidents (RTAs) are a major cause of misery, disability and death globally, with a disproportionate number occurring in developing countries. With COVID-19 reaching pandemic proportion, a nationwide lockdown was announced on 24 March 2020 which resulted in the complete closure vehicular movement. This study aimed to assess the impact of lockdown on the number of RTAs brought to our rural tertiary care teaching hospital situated on National highway number 65.Methods: Medico-legal records were reviewed retrospectively at Kamineni institute of medical sciences hospital. The cases were classified into two groups. The pre-lockdown group included cases reporting to casualty from 1 April 2019 to 31 July 2019. The lockdown group included cases reporting to casualty from 1 April 2020 to 31 July 2020. Patient demographics, type of injury, time of injury, mode of injury were collected for all cases and analysed using simple mathematical tools.Results: There was a significant decrease in the total number of RTAs during lockdown phases 1 and 2 and during unlocking phases 1 and 2 by 52.1%. Bike skid was the most common mode of injury. The highest number of RTAs was observed between 6 am to 6 pm and the most commonly affected gender was male especially in the age group of 15-45 years.Conclusions: RTA numbers can be reduced by strict implementation of traffic rules and better road infrastructure. One positive effect of the measures implemented to control the spread of COVID-19 was the reduction of traffic accidents and mass casualties.
