Svetlobni opozorilniki hitrosti v cestnem prometu : diplomsko delo
Bojan Kerin, 2010, undergraduate thesis

Abstract: V diplomski nalogi smo se osredotočili na področje povečanja prometne varnosti s pomočjo svetlobnih opozorilnikov hitrosti. Na kratko smo poskušali povzeti trenutno stanje varnosti v cestnem prometu na področju Evropske unije in jo primerjali z nacionalno problematiko. Pod drobnogled smo vzeli problematiko omejevanja hitrosti, ki je ključni faktor prometnih nesreč s hudimi telesnimi poškodbami in s smrtnim izidom, ki puščajo posledice tako na ljudeh kot tudi na samem gospodarstvu. Po študijah, ki smo jih opravili (pri izdelavi diplomskega dela), smo prišli do zaključka, da bi uporaba svetlobnih opozorilnikov hitrosti pripomogla k izboljšanju prometne varnosti, še zlasti na črnih točkah. Z uporabo takšnih naprav se izboljša percepcija prometne signalizacije zaradi osvetlitve iz sekundarnega vira svetlobe. Uporabljamo jih lahko v namene statističnih analiz stanja na cestah. Zaradi omejevanja hitrosti se posledično izboljša tudi kakovost življenja ljudi, ki živijo neposredno ob cesti, hkrati pa se doseže zmanjšanje izpustov strupenih plinov iz vozil. Z modifikacijo bi lahko svetlobne opozorilnike hitrosti uporabljali tudi na nivojskih prehodih čez železnico, ki bi nadomestili drage zapornice. Prednost svetlobnih opozorilnikov hitrosti je možnost njihove nadgradnje in uporabe za prihajajoče inteligentne prometne sisteme.

The method of recognition of forms when trying to select street direction
Štefan Novak, Darja Topolšek, 2009, original scientific article

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.

New approach to determining visibility length on passive protected level railroad crossings
Drago Sever, 2012, short scientific article

Abstract: The paper is based on the question whether the existing (legislation determined) method for determining the visibility length on passive protected level railroad crossings insures the relevant level of traffic safety. It has been recognised that using of such method does not provide stopping of road driver vehicles in front of railroad crossing in all conditions. Based on such conclusion a new approach to determining visibility length on passive protected level railroad crossing is proposed. The new approach is based on the assumption that it is necessary, primarily on level railroad crossings with local roads to recognize the worst possible and expected road and weather conditions. The testing of the proposed method in the real environment has shown that at lower speeds of road vehicles there is almost no difference, and that important benefits are recognised for the speeds of 30 and 50km/h where longer stopping distances of road vehicles have been detected (road vehicle can stop safely in front of a rail crossing) with almost the same visibility lengths. The use of the proposed method could have important impact on the increase of traffic safety on passive protected level railroad crossings.

New type of roundabout: roundabout with “depressed” lanes for right turning - “flower roundabout”
Tomaž Tollazzi, Marko Renčelj, Sašo Turnšek, 2001, short scientific article

Abstract: Recently, many of the foreign traffic-safety analyses point out the low level of traffic safety in multi-lane roundabouts. This problem is resolved in several ways in different countries; however, the solution, whereby the number of conflict points is diminished (e.g. turbo roundabout) has proven to be the most successful. However, the turbo roundabout also has its deficiencies: it has conflict crossing points and larger reconstruction of the existing two-lane roundabout is needed when the turbo roundabout is to be implemented instead of the existing one. In the paper a new type of roundabout has been introduced; the roundabout with “depressed” lanes for right turning (“the flower-roundabout”). Financially speaking, the main advantage of the new type of roundabout is that it can be implemented within the dimensions of the already existing “normal” two-lane roundabout. From the traffic-safety point of view, the main advantage of the new type of roundabout is that it has no crossing conflict points.

Prevention of wrong-way driving on freeways
Darja Topolšek, 2007, review article

Abstract: Traffic accidents that occur on freeways often end tragically because of high driving speed. Wrong-way driving is also one of the causes of accidents on freeways. Research is based on the analysis of traffic accident data caused by wrong-way driving on freeways and considering valid technical specifications for connections and junctions design elements. Research is based on the analysis of the data of traffic accidents that occurred because of wrong-way driving on freeways and on the consideration of valid technical specifications concerning connections and junction design elements. The thesis presents possible countermeasures for prevention of wrong-way driving and consequential decrease in the number of traffic accidents. The proposed prevention countermeasures of wrong-way driving on freeways could greatly reduce incorrect traffic vehicle movements that are the consequence of wrong-way driving and thus positively enhance the traffic safety level on freeways.

System dynamic model of measures for reducing the number of road accidents due to wrong-way movement on motorways
Darja 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.

Traffic safety of older drivers in various types of road intersections
Tomaž Tollazzi, Marko Renčelj, Vlasta Rodošek, Borut Zalar, 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 ITS
Darja Topolšek, Suzana Hribar, Marjan Sternad, 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.

Analysis of road traffic safety in Minna Niger State, Nigeria
Adebayo Owolabi Oyetubo, Oluwaseyi Joseph Afolabi, Muhammed Etudaiye Ohida, 2018, original scientific article

Abstract: Road traffic accident is one of the major causes of death in Nigeria. Road accidents have taken away so many lives in Nigeria today that hardly does any single disease match its mortality prowess. People have died prematurely and properties worth several millions of Naira have been lost as a result of road traffic accident. This paper gives a full discussion on road traffic safety issues and the methodology used were through the collection of data using questionnaire and accident information from the Nigeria Police Force, FRSC etc. The primary information for this research was sourced through the use of structured questionnaire, personal observation and interviews of road users in the study area. Secondary data emanated from published and unpublished sources such as government records, internet, journals, books etc. The findings were presented in descriptive and inferential form using frequencies, percentages, tables, mean and chi-square analytical techniques. The findings from the study revealed among many others; that Male involved more in road accident compare to female counterpart in Minna Niger State. Private car had more accident compare to Taxi, The number of accident in each zone does not depend on the population of that zone, etc.

Introduction of the concept of "Rescue Sheet" in road traffic
Vanna Boroša, 2019, master's thesis

Abstract: In this master's thesis, an analysis was made of the way fire departments operate in rescuing injured passengers from vehicles in an event of a car accident. In order to make it easier to understand the core of master's thesis, the paper defines terms such as the "golden hour", which is essential for the survival of injured passengers in a car accident. The analysis also includes information on the construction designs of the car and how the construction of the car could make it difficult for the firefighting units to operate. Some examples of interventions done by fire brigades and the problems encountered in everyday work on modern cars are also provided. In the concluding part of the thesis we have presented how fire departments can become more efficient, safer, faster, and economical in their daily work while rescuing passengers from vehicles. We have explained in more detail the notion of a “rescue sheet” and how it can be better implemented in the future. At the end of the paper, we have suggested the optimal ways of rescue sheet usage and have outlined the advantages and disadvantages of these uses.
