Abstract

Između Novog Vinodolskog i Karlobaga (dionica državne ceste D8) učestalo dolazi do zatvaranja prometa uslijed jakih udara vjetra (bure) za prvu skupinu vozila (autobusi na kat, vozila s kamp-prikolicom i motocikli). Zatvaranje ceste između Novog Vinodolskog i Karlobaga dešava se kada izmjereni sekundni udari vjetra na Balinskom vijaduktu premaše 25 m/s u slučaju mokrog kolnika i 30,6 m/s u slučaju suhog kolnika (prema važećem pravilniku Hrvatskih cesta). U ovom radu provedena je analiza prostorne raspodjele brzine vjetra na dionici ceste između Novog Vinodolskog i Karlobaga temeljem modula „Wind effect“, dostupnog u sklopu platforme QGIS, te brzine i smjera vjetra iz numeričkog atmosferskog modela Aladin-Hr u razdoblju 1998.-2001. U QGIS sučelju je za proračune brzine uzduž analizirane cestovne dionice korištena prostorna rezolucija podataka od 25m, a podaci o brzini i smjeru vjetra iz modela Aladin-Hr imaju prostornu rezoluciju od 4km i vremensku rezoluciju od 3h. Rezultati provedenih proračuna pokazali su da je moguće provesti zatvaranje ceste po pojedinim segmentima umjesto zatvaranja cjelokupne dionice između Novog Vinodolskog i Karlobaga.

Abstract (english)

Between Novi Vinodolski and Karlobag (section of state road D8) traffic is often closed due to strong gusts of wind (bura) for the first group of vehicles (double-decker buses, vehicles with caravans and motorcycles). The closure of the road between Novi Vinodolski and Karlobag occurs when the measured second wind gusts on the Balin Viaduct exceed 24 m/s in the case of wet pavement and 30.6 m/s in the case of dry pavement (according to the current rulebook of Hrvatske Ceste). In this paper, an analysis of the spatial distribution of wind speed on the road section between Novi Vinodolski and Karlobag was carried out based on the „Wind effect“ module, avaliable as part of the QGIS platform, and wind speed and direction from the numerical atmospheric model Aladin-Hr in the period 1998-2001. In the QGIS interface, a spatial dana resolution of 25m was used for speed calculations along the analyzed road section, while the dana on wind speed and direction from the Aladin-Hr model have a spatial resolution of 4 km and a temporal resoulution of 3h. The results of the calulculations showed that it is possible to close the road in invidual segments instead of closing the entire section between Novi Vinodolski and Karlobag.
