Driving simulator databases with dynamically changing road networks

For the various demands of the experiments carried out in the IZVW driving simulator a new concept for databases has been developed. The road network and the surrounding landscape is modeled in a topological way. During simulation, the geometrical representation is computed in a small area of visibility around the driver. The topological model facilitates the design of reproducible scenarios. The extent of the road network is almost unlimited and it can be changed without the driver noticing it. This modifications can be controlled either interactively by the researcher or automatically by the system. In the latter case, modifications of the network can be controlled by all system variables of the simulator.
