V2X Communications for Infrastructure-Assisted Automated Driving

Cooperative automated vehicles (CAVs) are expected to accommodate growing mobility demands with lower environmental impact and increased road safety. In urban scenarios, C-ITS will eventually permit the road infrastructure to meet these goals by monitoring, supporting and orchestrating CAVs' movements. For this purpose, V2X communications to concurrently guide CAVs at signalized intersections, consider platoons and inform about presence of non-cooperative road users are needed, among others. The design of these V2X communications is not trivial as it has to take into account application requirements as well as key aspects like backward compatibility and interoperability in already deployed scenarios. This paper will describe the V2X solutions adopted by the EU funded project MAVEN in this regard. By smartly extending or profiling current and new standard message sets, these solutions are suitable for real-road experiments and provide potential for future industrial adoption.
