Traffic is regularly counted and reported by Hrvatske autoceste, operator of the motorway, and published by Hrvatske ceste. Substantial variations between annual (AADT) and summer (ASDT) traffic volumes are attributed to the fact that the motorway carries substantial tourist traffic to the DalmatianAdriatic resorts. The traffic count is performed using analysis of toll ticket sales.
