Prospective risk-assessment exemplified by lane-changing driver assistance systems

Starting point of the prospective risk-assessment was the notion of risk: risk as the product of damage probability and damage power. The assessment was based on empirical data, which were collected on German motorways to analyze lane-changing manoevres. Results indicate a concentration on few dangerous types of lane-changing. Furthermore, a driving simulator was used for the comparison of different MMI-solutions: Guarding behaviour of the drivers remains stable, acceptance is high and the rate of critical lane changes tends to decrease.
