  Intelligent Transport Systems are crucial in the digital transformation of
transportation. The EC mandates the establishment of National Access Points
(NAPs) in each Member State, serving as common national interfaces for ITS data
exchange. While progress has been made in standardizing NAP data, integration
with operational ITS practices remain limited. This paper presents five NAP use
cases from the NAPCORE (National Access Point Coordination Organization for
Europe) CEF funded project. The first one outlines a National Virtual Traffic
Management Center offering real time visualized KPIs supporting motorway
traffic operations. The second focuses on NAP enabled Cooperative ITS and
dynamic traffic management services. Next use case involves a Pan European
interface, providing visualizations of data availability. The fourth use case
enhances the digitization of traffic management plans, among different TMC.
Finally, the fifth use case demonstrates a technical interface combining NAP
traffic data with meteorological information for KPIs on extreme weather
impacts on traffic.
