The Adriatic Port Community (APC) project aims at developing an IT system prototype based on the “Single Window” principle, namely a single interface improving the exchange of information among the ports involved in the initiative: Venice (IT), Ploče (HR) and Igoumenitsa (EL). APC’s goals include streamlining the administrative procedures related to the arrival and departure of ships especially in terms of time, managing the incoming and outgoing flows of goods in port areas and improving the management of parking areas within the port areas. Such system involves the creation of a single interface to enhance the exchange of information collected by means of the different IT systems developed by each partner.
