description: The aim of the ICT4CART project is to design, implement and test a versatile ICT infrastructure in real-life conditions, which will enable the transition towards higher levels of automation. It focuses on four high-value use cases: Smart Parking &amp; IoT services, dynamic adaptation of vehicle automation level based on infrastructure information, intersection crossing (urban) &amp; lane merging (highway), and Cross-border Interoperability. ICT4CART use cases have been carefully selected based on specific criteria, which are: i) alignment with EU policies and relevant forums and initiatives, ii) significant impact on connected automation, iii) the ability to generalise on the results (applicable in other scenarios and environments), and iv) interest to the consortium members and relevance to their industrial roadmaps. Moreover, these use cases are serving one of the main targets of the project, which is to show that the proposed and implemented ICT infrastructure architecture is flexible, adaptable and can serve the needs of various automated driving use cases (safety critical, comfort, etc.) with different requirements, across test sites with different capabilities. The ICT4CART use cases are either global or local, are either associated with network slices or not, are either using Edge Clouds/Computing or not, are using different radio technologies and can be used everywhere (roaming aspect). They also consider mechanisms for cyber-security, authentication, integrity and privacy. For this purpose, four test sites are involved in ICT4CART, namely in Austria, in Germany, in Italy and, finally, a cross-border site at the border between Austria and Italy. The main objective of WP7 is to integrate and test the solutions developed within ICT4CART in real-life conditions at the project test sites. This will be performed through the ICT4CART use cases and the corresponding traffic situations called “scenarios”, which have been defined in WP2. WP7 covers the integration of the modules that will be delivered by WP4, WP5 and WP6, and the data collection from all the test sites to be delivered to WP8 for the evaluation and impact assessment. The findings of WP2 include the specification of use cases, the analysis of market’s needs and system requirements. The ICT4CART Reference Architecture and key aspects of Flexible Networks, IT Environment and Cyber-Security &amp; Data Privacy are part of WP3. Based on these findings, this document (D7.2) outlines the concrete ICT architectures to be implemented at the different test sites. These architectures are adaptations of the high-level reference architecture (see D3.1 [1]). The aim is to cover the different ICT4CART use cases (see D2.1 [2]) which will be demonstrated in the corresponding test site while staying interoperable with the other test sites. First, the Introduction in Section 1 describes the aims of ICT4CART, i.e. the design and deployment of the ICT4CART technologies on the test sites covering all use cases. Section 2 summarises the ICT4CART Reference Architecture as developed in WP3 (see D3.1 [1]). After a brief description of the Architecture Adaptation Approach followed in Section 3, the following Sections 4 to 7 describe the ICT architectures that will be implemented in the test sites in Austria, Germany, Italy and the Cross-border test site. Finally, in Section 8, the interoperability of the demonstrated use cases and scenarios between the test sites is described on selected examples.
