Abstract

Između Klenovice i Senja (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 Klenovice i Senja 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 Klenovice i Senja 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 provedene analize pokazali su da nije potrebno provesti zatvaranje ceste D-8 na dionici Klenovica - Senj ukoliko se na referentnoj anemografskoj postaji za cestu D-8 (Balinski most) registrira premašenje maksimalno dopuštenih brzina vjetra. Zaključak je kako bi se izgradnjom infrastrukture poput burobrana na kritičnim točkama moglo umanjiti utjecaj vjetra na sigurnost prometa te izbjeći češće zatvaranje prometnice.

Abstract (english)

Between Klenovica and Senj (on the D8 state road section), traffic is frequently closed due to strong wind gusts (bura) for the first category of vehicles (double-decker buses, vehicles with caravans, and motorcycles). The road closure between Klenovica and Senj occurs when wind gusts measured at the Balinski Viaduct exceed 25 m/s in wet road conditions and 30.6 m/s in dry road conditions (according to the current regulations of Croatian Roads).
In this study, an analysis of the spatial distribution of wind speed along the road section between Klenovica and Senj was conducted using the "Wind effect" module available in the QGIS platform, along with wind speed and direction data from the Aladin-Hr numerical atmospheric model for the period 1998-2001. In the QGIS interface, a spatial resolution of 25m was used for calculations along the analyzed road section, while the wind speed and direction data from the Aladin-Hr model have a spatial resolution of 4km and a temporal resolution of 3 hours.
The results of the conducted analysis show that it is not necessary to close the D-8 road section between Klenovica and Senj if the reference anemographic station for the D-8 road (Balinski Most) registers a wind speed exceeding the maximum allowed value. The conclusion is that by constructing infrastructure such as windbreaks at critical points, the impact of wind on traffic safety could be reduced, thereby avoiding more frequent road closures.
