Abstract

Prometni znakovi su sredstvo komuniciranja u prometu. Osnovna zadaća im je omogućiti sigurno odvijanje prometa upozoravanjem na moguće opasnosti, postavljanjem obveza, zabrana i ograničenja, vođenjem prometnog toka te informiranjem sudionika u prometu. Da bi prometni znakovi mogli izvršavati svoju funkciju moraju biti tehnički ispravni, pravilno postavljeni i vidljivi u svim uvjetima vožnje. Na vidljivost prometnih znakova utječu brojni čimbenici poput vremenskih uvjeta, mjesta postavljanja znaka, njegove veličine, oblika i starosti itd. No za noćnu vidljivost najvažnija karakteristika prometnih znakova je razina retrorefleksije. Prometni znakovi čija je razina retrorefleksije ispod minimalne propisane vrijednosti ne mogu u potpunosti ispunjavati svoju zadaću, naročito u uvjetima smanjene vidljivosti, te ih je zbog osiguravanja željene razine prometne sigurnosti potrebno zamijeniti novima. Cilj ovog završnog rada je na temelju podataka o tehničkim karakteristikama prometnih znakova dobivenih ispitivanjem provedenim od strane Zavoda za prometnu signalizaciju, Fakulteta prometnih znanosti, Sveučilišta u Zagrebu, analizirati prometne znakove na državnim cestama na području Zadarske županije kako bi se utvrdila njihova kvaliteta.

Abstract (english)

Traffic signs are the means of communication in traffic. Their basic task is to enable safe traffic by warning of possible dangers, setting of obligations, prohibitions and restrictions, running the traffic flow and informing the traffic participants. In order for traffic signs to perform their function, they must be technically correct, properly positioned and visible in all driving conditions. Traffic signs visibility is influenced by a number of factors such as weather conditions, place of positioning, size, shape and age etc. But, for the nighttime visibility their most important characteristic is retroreflection. Traffic signs whose retroreflection levels are below the minimum prescribed values can not fully fulfill their tasks, especially under reduced visibility conditions, and should be replaced by new ones to ensure the desired level of traffic safety. The aim of this paper is to analyze traffic signs on state roads in the Zadar County area in order to determine their quality based on the technical characteristics of traffic signs obtained by the Department of Traffic Signalling of the Faculty of Transport and Traffic Sciences University of Zagreb.
