Abstract: Motorcyclists remain a disproportionately large group of vulnerable road users, with fatality rates significantly higher than that in other road groups. Additionally, fatal accidents involving motorcyclists have a more slowly decreasing trend in comparison to that of other road users, while the number of this kind of users is growing fast. For all these reasons, there is a need to understand what the key factors leading to fatal accidents are in order to identify the possible measures to minimize the accidents themselves or at least their consequences. This would permit, indeed, to positively impact the road traffic system, leading to the creation of the safest road traffic system possible, as it is the goal of the Sustainable Safety approach. The aim of this study is to dive into the mentioned problem, analyzing fatal motorcycle accidents in Slovenia over a decade, highlighting the key factors contributing to these incidents. By integrating data from four databases, the study evaluated accident trends, infrastructural elements, and rider behavior through a multi-stage analysis. Firstly, data were collected from four national, up-to-date databases that contain information about road accidents themselves, the road infrastructure, additional police data, and media descriptions. After merging this information into one comprehensive database, where each row represents all the data available for one accident, a general analysis of accidents’ trends over the considered 10-year period was developed, considering at first all fatal road accidents, then deepening it to accidents caused by a motorcyclist, and finally to single-vehicle accidents. A statistical analysis followed, aimed at identifying a statistical correlation between the accidents and the factors leading to them. The results of the first accident analysis indicated that excessive speed, incorrect driving direction, and overtaking maneuvers are the primary causes of fatal accidents, especially on non-urban roads preferred by motorcyclists. Single-vehicle accidents frequently involve collisions with roadside objects, including safety barriers and poles, underscoring the need for targeted infrastructural improvements. The following correlation analysis revealed that a total of seven factors were statistically significant: three human factors (age, gender, experience)—which were the ones with the strongest correlations—one infrastructural factor (pavement width), and three factors belonging to external conditions (accident type, cause, and location). Of these, four were positively correlated to the causer, while three, i.e., pavement width, causes, and road location, were negatively correlated. This study provides a foundation for future research on less severe accidents and proactive risk behavior analysis, aiming to improve motorcyclist safety comprehensively.

Abstract: Naloga se nanaša na prometno-varnostno analizo glavne ceste G1-1 Dravograd-Maribor. V nalogi ni obravnava celotna dolžina glavne ceste G1-1 Dravograd–Maribor, ampak samo del cestnega odseka, in sicer G1-1 Radlje–Selnica, v dolžini 24,907 km. Začetek le-tega je v začetni stacionaži cestnega odseka G1-1 0243 Radlje–Brezno v občini Radlje ob Dravi, konča pa se pri dolžini 6,211 tekočega km cestnega odseka G1-1 0245 Ruta–Selnica v občini Selnica ob Dravi. Prometno-varnostna analiza je narejena na podlagi podatkov o prometnih nesrečah, ki so se pripetile na cestnem odseku G1-1 Radlje–Selnica v obdobju 10 let, tj. med leti 2008–2017. Analiza prometnih nesreč je sestavljena iz dveh delov. V prvem delu so analizirane prometne nesreče, nastale v in izven naselij na cestnem odseku G1-1 Radlje–Selnica in po krajših cestnih odsekih G1-1 0243 Radlje–Brezno, G1-1 0244 Brezno–Ruta ter G1-1 0245 Ruta–Selnica, saj le-ti trije krajši cestni odseki sestavljajo cestni odsek G1-1 Radlje–Selnica. V drugem delu analize pa je v krajši obliki podana analiza podatkov prometnih nesreč, ki so se pripetile v naseljih Vas, Brezno in Ožbalt skupaj. Na podlagi podatkov o (stacionažah in posledicah) prometnih nesrečah je uporabljena metoda za določanje nevarnih cestnih odsekov. Le-ta upošteva tri prometno-varnostne kriterije, na osnovi katerih so določeni nevarni cestni pododseki v in izven naselij, ki se zaradi različnih omejitev hitrosti v metodi določajo ločeno. Pregled varnosti v cestnem prometu (RSI) smo izvedli na območju dveh nevarnih cestnih pododsekov izven naselja, ki sta locirana na cestnem odseku G1-1 0243 Radlje–Brezno in na cestnem odseku G1-1 0245 Ruta–Selnica, ter na enem nevarnem cestnem pododseku v naselju Brezno. Na podlagi RSI so podani morebitni ukrepi z namenom izboljšanja prometne varnosti na nevarnih cestnih pododsekih.

Abstract: In industrialized countries people over 50 years of age represent a rapidly growing part of population. Their lifestyle is also becoming more active, which means that the percentage of older drivers in the population of all drivers is also increasing. Many different studies have shown that elderly drivers are more frequently involved in specific types of accidents, especially at intersections. In the past 15 years there was a trend of increasing popularity of roundabouts in Slovenia. Their introduction was generally supported by the arguments of increased traffic-flow capacity and traffic safety as well. The studies on which these arguments are based were performed with an “ideal” type of driver in mind; the one that fully understands new rules and reacts correctly in all situations that may occur at such intersections, where there are no light signals to guide them. An elderly person does not necessarily conform to that ideal and if the percentage of elderly drivers became significant, the premises of the above mentioned studies may not be correct anymore which in turn implies that their results could also be questioned. The present study concentrated on the evaluation of traffic safety of elderly drivers, at various types of intersection, from their own perspective. Various statistical analyses of obtained data were performed. The most important finding was that we may claim, with high degree of probability, that the average person of the age of over 60 feels more unsafe at double-lane roundabouts than they would feel had the same intersection been equipped with traffic lights. Elderly traffic participants will always cause more accidents or participate in them due to hazardous factors. Challenge, arising from many different studies and researches, is in studying what measures and solutions can reduce the risk for elderly participants.

Abstract: Modern complexity of management is associated with important decision making, confronting a great number of useless in- formation. Selection of information - the choice of only quality, i.e. essential ones, is a big problem in managerial decision- making. Implementation of systemic approach i.e. systemic thinking can help dealing with it. It is known that decision-making based only on intuition is insufficient, especially nowadays, in the time of global business. Therefore, managers have to operate with adequate knowledge capital. It is synergetic composition of inborn talents, feelings, abilities as well as gained knowledge and experiences. DNT put this capital knowledge into function of management decision- making, thus easier and holistic information management needed for quality and efficient and successful problem solving. It enables managers to be creative, co-operative and interdisciplinary. It opens possibilities for combination of theory and practice in the decision making processes, as presented in our contribution. Quality, holistic management decision making, create competitive advantages. It can be proved by a practical example of de- cision making about preventive measures in the winter time (roads gritting and ploughing). Great importance of quality, timely and enough holistic information is presented with the model of Short Term Road Ice Prediction, which gives information for quality decision making.
