Validation Tests for SCOOP@F wave 2

publié le 6 août 2019

Validation tests for SCOOP wave 2 were conducted in the last quarter of 2018 and the first quarter of 2019. SCOOP@F wave 1 tested and validated the C-ITS use cases using ITS G5 communication technology. SCOOP@F wave 2 focused on a hybrid communication technology, ITS G5 and cellular, and the development of new C-ITS use cases.

 

The testing methodology was improved from wave 1 for the SCOOP@F wave 2 validation tests. The goal was to “industrialize” the writing of Test plans. This was made possible by the introduction of templates based on the recommendations of the ISTQB committee. Additionally, centralized tools to manage traceability and prepare and run test series increased the reliability of this first phase of work.

Subsequently, the test execution phase was used to assess the interoperability between the various partners, between the different prototypes and through the various C-ITS use cases chosen for this wave 2 (3 new use cases in addition to the previous ones).
 
On the one hand, between October 2018 and March 2019, the partners held around 20 bilateral test meetings. These sessions enabled to adjust the development of prototypes, whether for communication between vehicles and roadside units, with the French national ITS station or even in conjunction with road operators’ platforms. The results, with prototypes that had activated the management of message signatures and their verifications, were conclusive and validated the complete hybrid end-to-end tests for SCOOP@F wave 1 use cases. During the tests, the SCOOP@F wave 2 use cases were the topic of a few discussions, especially concerning the cybersecurity aspects, and will be definitively validated during a future test session.
 
On the other hand, university laboratory tests were also used to formalize unit tests of roadside units ; this concerned the “C3 – In-vehicle signage, embedded VMS” use case. In the same way as for the bilateral tests, the results will be consolidated during a future test session.
Finally, several test runs on open roads were shared with the TestFests event as part of the InterCor project. This underscored the interoperability with certain foreign countries (Belgium, Netherlands and United Kingdom) in addition to the national partners. These test series were split over two sites, one in France at the Reims-Champagne-Ardennes University and the other in Antwerp, Belgium, and were conducted at the end of the first quarter of 2019.

tests represent several hundred km run on open roads, thousands of DENM, IVIM and CAM messages sent and received, and dozens of devices used for each session. Overall, interoperability worked well between the different participants. However, given the heterogeneous levels of development between the different prototypes, several patches were used to overcome some problems.

These various results confirm the need to improve the national and European validation tests during the next validation sessions and increase the level of requirements expected from partners in these activities with the aim to standardize the C-ITS tests preparation and execution. These sessions will be organized within the scope of other projects that take over from SCOOP@F : C-Roads FR, INDID.
