Abstract: The methods concerned together with their characteristics of technical advantage exploitation affects the realization times and costs of the transport. The proper selection of a street would greatly affect those costs of transport that can be reduced as well as the speeds of the realization which could be accelerated. This article shows one of the methods of recognition of the forms with a test on a street type selection example. The aim of this article is showing the possibilities of the form recognition usage in the traffic and transport system. This sort of selection and classification is needed when the necessity to quickly decide about the direction of movement, particularly in special circumstances, arise.

, 2007, original scientific article
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.

System dynamic model of measures for reducing the number of road accidents due to wrong-way movement on motorwaysDarja Topolšek
, Martin Lipičnik
, 2009, short scientific article
Abstract: This paper provides a system dynamic model for reducing the number of motorway accidents due to wrong-way driving. Motorway accidents are often fatal due to high speeds. It is therefore necessary to carry out all the possible countermeasures in order to achieve adequate traffic management. One of the reasons for motorway accidents is driving in the wrong direction. Based on the analysis of the data on motorway accidents caused by driving in the wrong direction and based on the knowledge of individual project elements of junctions and slip roads, this paper will focus on this area. The possible countermeasures, presented here for preventing drivers from driving in the wrong direction on motorways drastically reduce the number of U-turn maneuvers that result in driving in the wrong direction and influence the level of safety on motorways. With the help of this model of system dynamics the countermeasures for reducing the number of such drivers will be confirmed and their effects will be shown.

, 2010, review article
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.

Road traffic safety in conjunction with in-vehicle ITSDarja Topolšek

, 2014, original scientific article
Abstract: Interest in Intelligent Transportation Systems comes from the problems caused by traffic congestion, road accidents and air pollution. Traffic congestion continues to grow worldwide as a result of increased motorization, population growth, changes in population density and urbanization. Interest in ITS can also be attributed to reducing road accidents and increasing traffic safety. The most common causes for road accidents are excessive speed, inattentive driving and ignorance of the right-of-way rules. To eliminate these causes, experience, knowledge of traffic regulations and a new car are not enough % vehicle safety systems have to take part as well. Therefore, the European Union issued a directive on the installation of intelligent systems, whose functions are active support during driving, warning the driver in dangerous situations and alerting passengers of the car in case of irregularities in motor function or actions carried out by the driver that may cause danger, such as swerving while falling asleep. These systems help drivers to avoid accidents, and in the event of a collision, an emergency call is automatically made. Furthermore, they can be used to regulate traffic patterns or to reduce engine performance, which would reduce pollution. With these benefits in mind, the EU has indicated to the automotive industry that installation of these new Intelligent Transportation Systems should be mandatory in their new vehicles.

Prometno-varnostna analiza cestnega odseka Dravograd-MariborMateja Knežar
, 2018, master's thesis
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.
