Validation tests for Wave 2 of SCOOP took place in the last quarter of 2018 and the first quarter of 2019. Wave 1 of SCOOP@F allowed for the testing and validation of C-ITS use cases using ITS G5 communication technology. Wave 2 of SCOOP@F focused on a hybrid communication technology, combining ITS G5 and cellular, and the development of new C-ITS use cases.

For the validation of SCOOP@F Wave 2, the testing methodology was improved compared to Wave 1. The goal was to industrialize the drafting of Test Plans. This was made possible by implementing document models based on ISTQB committee recommendations. Additionally, centralized tools were used to manage traceability, prepare test campaigns, and execute them, ensuring the reliability of this initial phase of work.

In the second phase, the realization of the tests aimed to assess interoperability between different partners, prototypes, and the various C-ITS use cases chosen for Wave 2 (three new use cases in addition to the previous ones).

Between October 2018 and March 2019, about twenty bilateral test meetings between partners took place. These sessions allowed for adjustments in prototype development, whether for communication between vehicles and roadside units, with the national node, or in connection with road manager platforms. The results, with prototypes that had enabled message signature management and verification, were conclusive and validated the complete hybrid chain for SCOOP@F Wave 1 use cases. The SCOOP@F Wave 2 use cases were discussed, particularly regarding security, and will be definitively validated in a future test session.

Moreover, university laboratory tests formalized the unit tests of roadside units, specifically for the use case “C3 – In-vehicle signage, embedded VMS.” As with bilateral tests, these results will be consolidated in a future test session. Finally, several joint road test campaigns were conducted alongside the TestFests event as part of the InterCor project. This highlighted interoperability with some foreign countries (Belgium, Netherlands, United Kingdom) in addition to national partners. These test campaigns were held at two sites: one in France at the University of Reims-Champagne-Ardenne, and the other in Belgium in Antwerp, at the end of the first quarter of 2019.

These tests covered several hundred kilometers, thousands of DENM, IVIM, and CAM messages, and dozens of devices implemented at each session. Overall, interoperability worked correctly between the different actors. However, given the heterogeneous development levels among the various prototypes, several patches were necessary to address these issues.

These results confirm the need to continue national and European validation tests in future sessions organized under other projects succeeding SCOOP@F (C-Roads FR, INDID) and to increase the expected level of requirements from partners in these activities to achieve industrialized validation of C-ITS.
