This demo shows a complete V2X communication using open-source tools for an adaptative cooperative collision avoidance service. The V2X communication is composed of two on-board units (OBUs) using OpenC2X and a Road-Side unit (RSU) performing as a V2X manager with Vanetza. The OBUs aim to be located inside the vehicles to communicate both in and out-car and the RSU is located on urban mobiliary (e.g., traffic lights). This demo represents a technical view on how a vehicle triggers a hazard event, an accident between two cars, and this event is broadcasted to nearby drivers to avoid a possible collision with the accidental vehicles, and maneuver to a different path.

This demo is running in a single physical computer where each element runs on a different Ubuntu virtual machine.

The main concepts to illustrate are:

• On-board units capable of sending periodically cooperative and hazard events messages.
• A road-side unit which receives and forwards vehicular messages for disruptive services.
• Hazard event messages broadcasted to reduce probability of collision.
• A scalable V2X communication system easily deployed.
