D300 is a state road connecting A9 with Umag and D21 state road in Buje. The road is 12.2 km long.[1][2]
The road, as well as all other state roads in Croatia, is managed and maintained by Hrvatske ceste, state owned company.[3]
Traffic volume
Traffic is regularly counted and reported by Hrvatske ceste, operator of the road.[4] Substantial variations between annual (AADT) and summer (ASDT) traffic volumes are attributed to the fact that the road connects A9 motorway carrying substantial tourist traffic to Umag, a major summer resort.
