Tech Paper: V2X Testing
Intelligent Transportation Systems (ITS) aim to provide services relating to different modes of transport and traffic management, enable users to be better informed and make safer, more coordinated and ‘smarter’ use of transport networks. Over recent years, the emphasis in intelligent vehicle research has turned to Cooperative ITS (C-ITS) in which the vehicles, pedestrians communicate with each other and/or with the infrastructure over wireless networks called V2X network. C-ITS can greatly increase the quality and reliability of information available about the vehicles, their location and the road environment. It improves existing services and will lead to new ones for the road users, which, in turn, will bring major social and economic benefits and lead to greater transport efficiency and increased safety.

Cooperative vehicular applications in future transportation ecosystems with complex architecture and hybrid radio access solutions call for new approaches in system testing and verification.
Strict requirements for the system under test regarding high performance, reliability, low latency, interconnection, interoperability, security and safety result in exceptional demands on the test system and affect the entire testing cycle from test design, execution and verification of results.
C-ITS services with the exchange of status information and sensor and environmental data allow “Cooperative Driving” the bridge technology for the transition from assisted driving to the long-term goal of highly automated and autonomous driving. Wireless communication with unpredictable and changing RF conditions and parallel connections to moving vehicles of different vendors and implementations is cumbersome. Vehicles are no longer isolated systems but are taking part in an interconnected transportation ecosystem.
