All kinds of scenarios can be tested. For example, when autonomous vehicles, vessels, drones and trains start to work together. By developing an open source digital twin, knowledge exchange between the modalities is stimulated. The Northern Netherlands is the only region in Europe where projects take place in all modalities. With the development of a tool, this knowledge can also be exchanged much more between the modalities. In addition, other regions from the Netherlands and abroad can also contribute their knowledge and experiences here through the open source method. The province of Groningen is currently working with robotTUNER to set up the tool.
