 A V2X communication software stack called [Vanetza](https://github.com/riebl/vanetza)  is integrated into the standalone autonomous driving software stack, [Autoware](https://github.com/autowarefoundation/autoware). The V2X stack and the autonomous driving stack can be decoupled, allowing other applications to utilize the V2X router as well. A high-level overview of the architecture is shown below.
