Abstract

The goal of the study was to investigate if the drivers behave in the same way when they are driving a motorcycle or a car. For this purpose, the Motorcycle Rider Behaviour Questionnaire and Driver Behaviour Questionnaire were conducted among the same drivers population. Items of questionnaires were used to develop a structural equation model with two factors, one for the motorcyclist's behaviour, and the other for the car driver's behaviour. Exploratory and confirmatory factor analyses were also applied in this study. Results revealed a certain difference in driving behaviour. The principal reason lies probably in mental consciousness that the risk-taking driving of a motorbike can result in much more catastrophic consequences than when driving a car. The drivers also pointed out this kind of thinking and the developed model has statistically confirmed the behavioural differences. The implications of these findings are also argued in relation to the validation of the appropriateness of the existing traffic regulations. Glavni namen raziskave je preučevanje morebitnih vedenjskih razlik motoristov pri vožnji z motornim kolesom ali avtomobilom. V ta namen je izvedena anketa v obliki dveh vprašalnikov med isto populacijo motoristov. Prvi vprašalnik zrcali motoristične vedenjske, drugi pa avtomobilistične vedenjske vzorce. Na osnovi zbranih podatkov ankete je razvit model strukturnih enačb z dvema faktorjema, eden se nanaša na vedenjske lastnosti vožnje z motorjem, drugi pa na vedenjske lastnosti vožnje z avtom. V procesu razvoja modela sta uporabljeni tudi eksploratorna in potrditvena faktorska analiza. Rezultati kažejo, da dejansko obstajajo določene razlike v voznem obnašanju. Glavni razlog za to je verjetno v mentalnem zavedanju motoristov, da rizična vožnja z motorjem lahko vodi do mnogo hujših posledic v primerjavi z vožnjo z avtom. Motoristi namreč posebej izpostavijo tovrstno dojemanje razlik pri vožnji z motorjem ali avtom, kar naš model tudi statistično potrdi. Implikacije teh ugotovitev so soočene z morebitno neustreznostjo obstoječe prometne zakonodaje.

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. Prometne nesreče na avtocestah so zaradi velike hitrosti vožnje velikokrat tragične. Eden od vzrokov nastanka prometnih nesreč na avtocesti je tudi nepravilna smer vožnje. Raziskovalno delo je zasnovano na analizi podatkov o prometnih nesrečah zaradi nepravilne smeri vožnje na avtocestah, ter na osnovipoznavanja posameznih projektnih elementov vozlišč in priključkov. Predlagani ukrepi za preprečevanje nepravilne smeri vožnje na avtocestah lahko v veliki meri zmanjšajo število nepravilnih prometnih manevrov, ki imajo za posledico nepravilno smer vožnje in s tem pozitivno vplivajo na raven prometne varnosti na avtocestah.

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. Članek podaja model zniževanja prometnih nesreč zaradi nepravilne smeri vožnje na avtocestah. Prometne nesreče na avtocestah so zaradi velike hitrosti vožnje velikokrat tragične, zato je potrebno izvesti vse možne ukrepe za ustrezno upravljanja prometa. Eden od vzrokov nastanka prometnih nesreč na avtocesti je nepravilna smer vožnje. Na podlagi analiz podatkov o prometnih nesrečah zaradi nepravilne smeri vožnje na avtocestah ter na osnovi poznavanja posameznih projektnih elementov vozlišč in priključkov se pričujoče delo usmerja na to področje. Predstavljeni možni ukrepi za preprečevanje nepravilne smeri vožnje na avtocestah v veliki meri znižujejo število nepravilnih prometnih manevrov, ki imajo za posledico nepravilno smer vožnje in s tem pozitivno vplivajo na raven prometne varnosti na avtocestah. S pomočjo modela sistemske dinamike bo potrjena upravičenost ukrepov za zmanjševanje števila primerov nepravilne smeri vožnje in prikazani njihovi učinki.

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. Zainteresowanie Inteligentnymi Systemami Transportowymi (ITS) wynika z problemów spowodowanych przeciążeniem ruchu drogowego, wypadkami drogowymi oraz zanieczyszczeniem powietrza. Przeciążenie ruchu stale wzrasta na całym świecie, jako rezultat wzrostu motoryzacyjnego, zwiększenia liczby ludności, zmiany w gęstości zaludnienia oraz urbanizacji. Zainteresowanie ITS może również być przypisane redukcji wypadków oraz zwiększenie bezpieczeństwa na drogach. Najczęstszymi powodami wypadków drogowych są nadmierna prędkość, nieuważne prowadzenie samochodu oraz ignorowanie zasad ruchu drogowego. By wyeliminować te powody, doświadczenie, wiedza o zasadach ruchu drogowego oraz nowy samochód nie są wystarczające – powinny tu również brać udział systemy bezpieczeństwa pojazdu. Dlatego też Unia Europejska ustanowiła dyrektywę o instalowaniu inteligentnych systemów, których funkcje to aktywne wspieranie podczas jazdy, ostrzeganie kierowcy o sytuacjach niebezpiecznych oraz powiadamianie pasażerów samochodu w razie nieprawidłowości w działaniu silnika lub o działaniach powodowanych przez kierowcę, które mogą powodować niebezpieczeństwo, takie jak zbaczanie z drogi w wyniku zasypiania. Systemy te pomagają kierowcom zapobiec wypadkom oraz w razie kolizji wykonują automatycznie telefon alarmowy. Co więcej, mogą być stosowane do regulowania wzorców ruchu lub redukcji osiągów silnika, co zmniejsza ilość zanieczyszczeń. Mając na uwadze te korzyści, Unia Europejska zaleciła przemysłowi motoryzacyjnemu, instalowanie Inteligentnych Systemów Transportowych w nowych pojazdach. Document type: Article

Abstract

The following paper aims to illustrate certain investigative activities in the forensic analysis and examination of the scene of traffic accidents. When a traffic accident occurs, the scene must be secured as soon as possible to enable professional and proper forensic investigation. Failure to secure the accident scene might result in losing or contaminating the traces, which makes it more difficult to prove or explain trace evidence in further procedure or even makes such evidence inadmissible. The topic is discussed from the viewpoint of crime scene examination, since analysing and investigating traffic accidents requires a great deal of expertise and attention of the investigators. Complex traffic accidents include feigned accidents, hit-and-run accidents as well as accidents in which the driver and passengers, dead or alive, need to be identified. In identifying the passengers, standard criminal investigation methods as well as police forensic and forensic medicine methods are followed. Such methods include confirming the identities with identity documents, other documents and vehicle ownership, fingerprints, biological traces, fibre traces, contact traces, traces of physical injuries on the driver and passengers, etc. According to the results obtained in fingerprint detection on human skin surfaces, this method can also be applied in confirming physical contact between the driver and the passengers in the accident, e.g. in the event of moving the victims and changing the scene of the accident. Namen prispevka je pojasniti določena preiskovalna dejanja pri analizi t.j. pri kriminalistično tehničnem oz. forenzičnem ogledu kraja prometne nesreče. V primeru prometne nesreče je treba za strokovno in pravilno forenzično preiskovanje čim hitreje zavarovati kraj. Če se kraj dejanja ne zavaruje, se sledi izgube ali kontaminirajo, kar vodi do težjega dokazovanja ali pojasnjevanja dokazov v postopku ali celo do njihove popolne nezmožnosti. Vidik obravnavanja je usmerjen v izhodišča ogledne dejavnosti, saj analiza prometnih nesreč v cestnem prometu in preiskovanje zahtevajo od preiskovalcev veliko znanja in pozornosti. Zelo zahtevni so primeri fingiranih prometnih nesreč, prometnih nesreč ko vozniki ali udeleženci zapustijo kraj dogodka ter nesreče, kjer je treba ugotoviti identiteto voznika in udeležencev, živih ali mrtvih. Ugotavljanje istovetnosti udeležencev poteka po ustaljenih kriminalističnih oz. forenzičnih ter sodnomedicinskih metodah. Mednje se prišteva tudi potrditev identitete po osebnih dokumentih, dokumentih in lastništvu vozil, prstnih sledeh, bioloških sledeh, sledeh vlaken in kontaktnih sledeh, sledeh telesnih poškodb voznika in udeležencev ip. Rezultati preiskave detektiranja prstnih sledi na površini človeške kože so pokazali, da je tudi tovrstno metodo možno uporabiti pri potrditvi fizičnega kontakta voznika z udeleženci v prometni nesreči, npr. pri premikanju žrtev in fingiranju kraja dejanja.
