TransAID Deliverable 7.2: System prototype demonstration (iteration 2)

Abstract

This deliverable is a direct successor of Deliverable 7.1, which has introduced all vehicles, test tracks, used hardware, and proposed system architectures of the different used components. D7.1 has also introduced several system requirements for each component and for each use case described in D2.1, which must be implemented. D7.2 shows the system architecture implementation for the different components of the infrastructure part as well as for the vehicle part. It is shown how both parts communicate in the real-world following D5.2 by presenting the finally used ASN.1 message definitions (in the Annex) and details about the communication software. In the project, real-world implementations have been performed at four partners. UMH was responsible for setting up the communication software required in all implementations. DLR assembled all use cases in several scenarios on the test track located in Peine-Eddesse in northern Germany. Dynniq implemented a C-ITS based highway merging as specified in use case 2.1 on public roads on the highway A13 in The Netherlands. HMETC finally took a closer look at ToC/MRM distribution in urban areas as specified in the combined use case 4.1-5 on a test track located in Griesheim, Germany. Besides the implementation, feasibility assessments of all TransAID measures have been performed. For this, each use case has been divided into test scenarios, which have been implemented in the real-world prototypes, demonstrated and assessed. Each test scenario is linked to related requirements set up in D7.1. During the feasibility assessment, the compliance with all requirements has been checked by project partner HMETC, who is taking the role of an OEM here. In addition, the overall "look and feel" of the prototype and the performance in each test scenario has been rated and described. In summary, nearly all requirements were fully met. Only in few cases the implementation deviates from the earlier requirement specification, sometimes due to new findings in the project, sometimes as not all implementations could be showcased due to the COVID-19 pandemic. Altogether, it could be shown that the TransAID measures can be put into real-world to help future automated vehicles to better cope with possible threats and to gain higher performance on the road. Nevertheless, further research is required to bring the measures to a higher Technology Readiness Level, up to series production. This is especially true for HMI design for vehicles and VMS (as this was not in scope of the project), vehicle automation behaviour in case of ToCs and MRMs, and I2V-MCM deconflicting.
