A3 (Croatia) - Traffic Volume

Traffic Volume

Traffic is regularly counted by means of a traffic census at toll stations and reported by Hrvatske autoceste. The reported traffic volume gradually decreases as the motorway chainage increases and as it passes by various major destinations and the interchanges that serve them. Thus the greatest volume of traffic is registered along Zagreb bypass, especially the Jankomir–Lučko section, with 41,549 vehicle annual average daily traffic (AADT). The busiest tolled section of the motorway is Ivanja Reka–Rugvica with 27,049 AADT and 34,543 vehicle average summer daily traffic (ASDT) figures. The traffic volume gradually decreases from that section eastward to the eastern terminus of the motorway, where the lowest AADT and ASDT figures are recorded. The traffic volume decrease is somewhat more pronounced at interchanges serving Slavonski Brod and the A5 motorway (Sredanci). The seasonal traffic volume variation ranges from a 28% increase on the busiest, Ivanja Reka–Rugvica, section to a 75% volume increase, as measured on the Županja–Spačva section. Average summer season traffic volume increase on the motorway is 55%. The AADT/ASDT ratio analysis does not include Zagreb bypass, as there are no ASDT data available for the bypass.
