20.500.12556/DKUM-99879 Ustreznost vertikalne cestnoprometne signalizacije na območju Pernice Adequacy of vertical road traffic signs in the Pernica area Prometna signalizacija je pomemben element cestne infrastrukture, saj udeležencem v prometu posreduje informacije, potrebne za varno in nemoteno odvijanje cestnega prometa. V diplomskem delu je predstavljena vloga vertikalne cestnoprometne signalizacije, obravnavane so zahteve glede postavitve, vidnosti, vzdrževanja in retroreflektivnih lastnosti prometnih znakov. Posebna pozornost je namenjena vplivu človekovih sposobnosti zaznavanja, svetlobnih pogojev in stanja prometnih znakov na njihovo pravočasno prepoznavanje. V praktičnem delu je analizirano stanje izbrane vertikalne cestnoprometne signalizacije na območju Pernice. S terenskim pregledom in meritvami koeficienta retrorefleksije so bile preverjene ustreznost postavitve, ohranjenost, vzdrževanost in svetlobnoodbojne lastnosti prometnih znakov. Rezultati so pokazali, da je večina obravnavanih znakov v zadovoljivem stanju, vendar so bile ugotovljene tudi nepravilnosti pri njihovi postavitvi, vzdrževanju in retroreflektivnih lastnostih. Primerjava meritev glede na starost znakov, vrsto svetlobnoodbojne folije in lokacijo ni pokazala, da bi na njihovo ohranjenost vplival samo posamezen dejavnik. Ugotovitve poudarjajo pomen rednih pregledov, ustreznega vzdrževanja in pravočasne zamenjave prometnih znakov za zagotavljanje njihove dobre vidnosti in večje prometne varnosti. Traffic signs are an important element of road infrastructure, as they provide road users with the information required for the safe and efficient flow of traffic. This diploma thesis presents the role of vertical road traffic signs and examines the requirements concerning their placement, visibility, maintenance and retroreflective properties. Particular attention is paid to the effects of human visual perception, lighting conditions and the physical condition of road signs on their timely recognition. The practical part analyses the condition of selected vertical road traffic signs in the Pernica area. Field inspections and measurements of the coefficient of retroreflection were used to assess the placement, physical condition, maintenance and retroreflective performance of the signs. The results show that most of the examined signs are in satisfactory condition, although certain deficiencies were identified in their placement, maintenance and retroreflective properties. A comparison of the measurements according to the age of the signs, the type of retroreflective sheeting and their location did not indicate that their condition was determined by any single factor. The findings emphasise the importance of regular inspections, appropriate maintenance and the timely replacement of road signs in order to ensure good visibility and improve road safety. vertikalna cestnoprometna signalizacija prometni znaki retrorefleksija koeficient retrorefleksije svetlobnoodbojna folija prometna varnost. vertical traffic signs road signs retroreflection coefficient of retroreflection retroreflective sheeting road safety. true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-08-28 12:20:09 2026-09-10 11:56:40 2026-09-11 03:08:02 0000-00-00 00:00:00 2026 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 VS_Dusic_Mitrovic_Miha_2026.pdf VS_Dusic_Mitrovic_Miha_2026.pdf 1 CE6C457CC4714FA0765C7C294A3DF28C 14d4c85e56d8aff8e2b4dd001d40c9a61d33cb3d9e1d92ed28c061edffb41374 ce66366f-acf8-11f1-b668-00155d0001be https://dk.um.si/Dokument.php?lang=slv&id=212061 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo 0 0 0
