CARMINAT is a European research program conducted under partnership and aimed at integrating a comprehensive information system into motor vehicles. The information may concern the vehicle itself or the traffic situation and other services. It is linked to a navigation and guidance system.Traffic information and services are broadcast by RDS. The route planner takes RDS messages into account to alter the route when necessary. Compatibility with the task of driving is ensured by ergonomic studies and testing.The research phase of Carminat will be followed by large scale pilot programs involving a fleet of vehicles on motorways and in large urban areas.
