The goal of this thesis work was to implement a communication standard enabling the so-called Vulnerable Road Users (VRUs) to communicate with one another as well as with vehicles. This protocol has been implemented first on a simulator and then on a physical device, i.e., an On-Board Unit (OBU). This allowed us to test the communication standard on the field, in a real world scenario. The first step, before the implementation of the communication protocol, was to create a scenario. A map containing both vehicles and VRUs, such as pedestrians, was created. Specifically, we took advantage of an online program, i.e., OpenStreetMap, to build the map for the simulated scenario and then, using Linux and Python APIs, I filled the map with vehicles and pedestrians, being them the most common type of VRUs we can find on the road.
