A8 (Croatia) - Traffic Volume

Traffic Volume

Traffic levels are regularly determined and reported by BINA Istra, operator of the motorway, and published by Hrvatske ceste. In 2010 the traffic volume was only measured in two sections: in the Učka Tunnel and between Lupoglav and Cerovlje. In 2011, traffic counting was started in each section of the A8 between Kanfanar interchange and the Učka Tunnel using the toll ticket counts. As of June 2012, only the ASDT figures for 2011 have been published. The largest AADT volume was recorded in the Učka Tunnel; it represents the only high-performance link between Istria and the rest of the Croatian motorway network.

The differences between the AADT and ASDT traffic volumes in 2010 are attributed to the motorway's carriage of substantial tourist traffic to the Adriatic Sea resorts along the Istrian peninsula. On average, the A8 motorway's ASDT is at least 65% more than the AADT. The largest increase of the ASDT relative to the AADT, 68%, is observed in the Veprinac–Vranja section (which includes the Učka Tunnel). During the summer of 2007, an ASDT of 14,000 was observed in the tunnel, prompting BINA Istra to consider preparing to construct the second tunnel tube. BINA Istra expects the motorways it manages to carry more than 20,000 vehicles per day during the peak tourist season periods.
