Abstract

Kako bi se osiguralo sigurno odvijanje prometa, posebnu pozornost je potrebno posvetiti prijenosu informacija sudionicima u prometu. Takve informacije sudionici ponajprije dobivaju prometnom signalizacijom, odnosno prometnim znakovima i oznaka na kolniku. Vidljivost prometnih znakova ovisi o retrorefleksiji i kromatici boja, to jest o retroreflektirajućem materijalu od kojeg su izrađeni. Kromatika boja predstavlja nijansu, zasićenost i svjetlinu boje, a značajna je za jasno uočavanje, prepoznavanje i čitanje prometnih znakova tijekom dana. Svrha rada je istražiti povezanost između retrorefleksije i kromatike boja prometnih znakova te na temelju provedene analize izraditi model za određivanje kromatike boja na temelju vrijednosti retrorefleksije. Cilj navedenog modela je na temelju izmjerene retrorefleksije odrediti kromatičnost prometnih znakova u svrhu utvrđivanja njihove tehničke ispravnosti. Na temelju dobivenog modela moguće je planirati aktivnosti zamjene tehnički neispravnih znakova s ciljem optimizacije sustava održavanja prometnih znakova, povećavajući time razinu sigurnosti prometa uz istovremeno smanjenje troškova i vremena potrebnog za ispitivanje njihove kvalitete.

Abstract (english)

In order to ensure safe traffic flow, particular attention should be paid to the transfer of information to the participants in traffic. Such information is primarily provided by traffic signaling with traffic signs and road markings. The visibility of traffic signs depends on the retroreflection and chromaticity, which is determined by the material from which they are made of. Chromaticity represents a shade, saturation and color brightness, and is important for noticing, recognizing and reading traffic signs information during daytime. The purpose of this research is to investigate the correlation between retroreflection and chromaticity of the traffic signs and to develop a model for calculating the color chromaticity based on the value of the retroreflection. The object of aforementioned model is to determine traffic signs chromaticity based on measured retroreflection in order to evaluate their technical validity. Based on the obtained model, it is possible to plan the replacement of technically invalid signs in order to optimize the traffic signs maintenance system and thereby to increase the level of traffic safety while at the same time significantly reducing costs and time needed to test quality and validity of traffic signs.
