Abstract

Retrorefleksija je pojava širenja svjetlosti kod koje se upadne zrake svjetlosti odbijaju od medija i vraćaju nazad prema svom izvoru te je kao takva ključan pojam za ostvarivanje vidljivosti prometne signalizacije i ostale opreme. Prometna signalizacija je ključna za informiranje sudionika u prometu i stoga je bitno osigurati njenu vidljivost prilikom dnevnih i noćnih uvjeta vidljivosti. Zato su izrađeni materijali u obliku mikroperli i mikroprizmi koji na principu retrorefleksije omogućuju vidljivost prometne signalizacije prilikom otežanih uvjeta vidljivosti. Cilj ovog rada je analizirati pojam retrorefleksije kao glavni uvjet vidljivosti prometne signalizacije. Uz to će se razraditi tematika ispitivanja retrorefleksije prometnih znakova i oznaka na cesti te pomoću navedenih istraživanja opisati utjecaj vidljivosti prometne signalizacije na ponašanje sudionika u prometu i tako na sigurnost cestovnog prometa.

Abstract (english)

Retroreflection is the phenomenon of light propagation in which incident light rays are reflected from the medium and return back to their source, and as such is a key term for achieving the visibility of traffic signalization and other road equipment. Traffic signalization is essential for informing traffic participants and therefore it is essential to ensure its visibility during daytime and nighttime visibility conditions. That's why materials in the form of microbeads and microprisms were made, which, based on the principle of retroreflection, enable the visibility of traffic signals in difficult visibility conditions. The aim of this paper is to analyze the concept of retroreflection as the main condition for the visibility of traffic signals. In addition, the topic of examining the retroreflection of traffic signs and markings on the road will be elaborated, and with the help of the mentioned research, the influence of the visibility of traffic signals on the behavior of road users and thus on the safety of road traffic will be described.
