Cooperative Driving is one of the main Application Areas to improve Road Safety and Traffic Efficiency. The Simulator for Cooperative Automotive Network (SCAN) project, developed by Renault, Direction de la Recherche, France, is a network of graphics stations, each station representing a Cooperative Vehicle, functioning in real time. Its major constitutive units include a decision making engine, a communication system, enabling communication with other vehicles as well as with the infrastructure, and a three-dimensional graphics computing and display unit with an appropriate man-machine interface, cockpit or mouse-keyboard. SCAN enables the validation of inter-vehicle communication concepts as well as the driver assessment of the new product in a variety of traffic conditions. The reconfigurable simulation software also allows for applicability testing of various positioning or communication systems and ergonomics analysis, especially for head-up display design. The objective of the DRIVE project V 1048, DOMINC (Driving on Motorway IN Cooperation) is to study advanced Control Strategies and Methods for Motorway RTI Systems of the Future. Large scale motorway traffic flow simulation is achieved by interfacing SCAN with SPEACS (Simulation Package for the Evaluation of Advanced Control Strategies), developed by Mizar and CSST in Italy. Among a large number of vehicles, generated in this case by the experimental model of SPEACS, some equipped vehicles are communicating with each other, driven interactively by SCAN.
