A number of the Intelligent Transportation System (ITS) solutions have been implemented in conventional vehicles in recent years. In the not too distant future driverless vehicles will share the roads with vehicles driven by human beings. In this paper, a novel algorithm for switching from one driving maneuver to another is proposed. The interface has been developed in C++ Visual Studio and using a 3D simulator with the data provided by a GPS and lidar sensors. Specific driving tasks such as lane following, curve driving and roundabout driving have been analyzed and tested with good simulations results obtained.
