Abstract

Oznake na kolniku sastavni su dio prometne signalizacije te predstavljaju skup longitudinalnih i transverzalnih crta, natpisa i simbola kojima se oblikuju površine prometne infrastrukture. Njihova osnovna svrha je omogućiti sigurno vođenje svih sudionika u prometu te upozoriti ih na opasna mjesta na prometnici. Postizanjem retrorefleksije oznaka noću na neosvijetljenim prometnicama i u nepovoljnim vremenskim uvjetima omogućuje se bolja vidljivost, pravovremeno uočavanje i prepoznavanje potencijalno opasnih situacija. Cilj ovog diplomskog rada je utvrditi postoji li statistički značajna povezanost između retrorefleksije oznaka na kolniku i prometnih nesreća na državnim cestama Republike Hrvatske u periodu 2013.-2015. godine. U detaljnoj analizi statistički su obrađeni podaci o prometnim nesrećama s posljedicama i razine retrorefleksije oznaka te je uzet u obzir i parametar prosječnog godišnjeg dnevnog prometa. Dobiveni podaci potvrdili su početnu pretpostavku te se došlo do zaključka da slabljenjem koeficijenta retrorefleksije oznaka značajno se smanjuje vidljivost istih i povećava broj prometnih nesreća.

Abstract (english)

Road markings are an integral part of traffic signaling and they represent a set of longitudinal and transversal lines, inscriptions and symbols that shape the surface of the traffic infrastructure. Their main purpose is to ensure the safe driving for all traffic participants and to warn them of dangerous spots on the road. By using retroreflection of road markings during night and in conditions of reduced visibility, it is possible to achieve better visibility, detection on time and recognition of potentially dangerous situations. The aim of this graduate thesis is to determine whether there is a statistically significant correlation between the retroreflection of road markings and traffic accidents on the state roads of the Republic of Croatia in the period 2013-2015. In conducted analysis, the data about traffic accidents with consequences and the level of the retroreflection were taken into account, as well as the parameter of average annual daily traffic. The obtained data confirmed the initial assumption and it was concluded that by lowering the retroreflection coefficient of the road markings, the visibility is being significantly reduced and the number of traffic accidents increased.
