ANALYSIS OF THE IMPACT SPEED OF VEHICLES ON ROAD SAFETY

Z razvojem vse močnejših in kakovostnejših vozil, ki lahko razvijejo velike hitrosti so se povečale tudi posledice prometnih nesreč pri katerih nemalokrat pride do najhujših posledic s smrtnim izidom in hudih telesnih poškodb. V statistiki prometnih nesreč, ki jih zasledimo v policijskem poročilu je najpogostejši vzrok za prometne nesreče neprilagojena hitrost. Vendar pa bi bilo zelo dobo ločiti katera hitrost je glavni vzrok za prometno nesrečo: neprilagojena hitrost je tista hitrost, ki ni prilagojena na cestne in vremenske razmere v danem trenutku ali prekomerna oz prekoračena hitrost je tista hitrost, ki je višja od omejene hitrosti, ki je predpisana z prometnim znakom. V diplomski nalogi smo analizirali podatke za tri števna mesta v preteklih treh letih in podali rezultate koliko vozil prekorači omejeno hitrost na posameznem števnem mestu in koliko prometnih nesreč se je zgodilo na posameznih števnih mestih. Podatki iz števnih mest predstavljajo dejansko stanje kako vozimo in so neodvisni od policije. Glede na analizirane podatke smo ugotovili, da veliko vozil prekorači omejeno hitrost pa se ne zgodijo prometne nesreče. V prihodnje bi bilo potrebno ugotoviti, kje je vzrok za nastanek nesreče.Abstract With the development of more powerful vehicles of better quality that can reach high speed, also consequences of traffic accidents, which often have fatal consequences with following death and severe bodily injuries, have increased. In the statistics of traffic accidents the most frequent reasons for traffic accidents is unadapted speed according to police reports. But it would be very good to differentiate what speed is the main reason for a traffic accident: unadapted speed is the speed that is not adapted to street and weather conditions in a given moment or excessive respectively exceeded speed is the speed, which is higher than the limited speed, required by the traffic sign. In the thesis we analysed the data at three control spots in the past three years and gave the results how many vehicles exceeded the restricted speed at each single control spot and how many traffic accidents had happened on the single control spots. The data from the control spots represent the actual state how we drive and are independent from the police. In respect to the analysed data we ascertained that many vehicles had exceeded restricted speed, but that no traffic accidents had happened. In the future it is necessary to find out where the reason for the appearance of accidents lies
