Traffic volume

Traffic is regularly counted and reported by Hrvatske ceste, the operator of the road.^[5] Substantial variations between annual (AADT) and summer (ASDT) traffic volumes are attributed to the fact that the road serves as a connection to the A1 motorway and the D8 state road carrying substantial tourist traffic.
