A6 (Croatia) - Traffic Volume

Traffic Volume

Traffic is regularly counted by means of a traffic census at toll stations and reported by Autocesta Rijeka–Zagreb, the operator of the motorway, and published by Hrvatske ceste. The reported traffic volume exhibits no significant variations as the motorway chainage increases, and as it passes by various major destinations and the interchanges that serve them, except at the Vrata interchange, where traffic to and from Krk Island, Crikvenica, and Novi Vinodolski flows. The greatest volume of traffic is registered between Delnice and Vrata interchanges—with a 12,600-vehicle annual average daily traffic (AADT), and a 21,150-vehicle average summer daily traffic (ASDT) figure. Sections south of Kikovica interchange likely carry substantial traffic volume as they serve Rijeka commuter traffic as well as the volume registered between the Oštrovica and Kikovica interchanges. However, no traffic volume figures are published for those sections, since motorway traffic is counted by means of toll ticket sales analyses, and the sections south of Kikovica interchange are not tolled.

Substantial variations observed between AADT and ASDT are normally attributed to the fact that the motorway carries significant tourist traffic to Istria and Kvarner Gulf. The seasonal increase in traffic volume ranges from 41% on the Oštrovica–Kikovica section to 69% as measured on the Bosiljevo 2–Vrbovsko section. The average summer-season traffic volume increase on the motorway is 65%.
