Abstract
This paper describes a method to diagnose both driver's situation awareness (SA) and behavior based on actual rear-end collision and near-miss data. Characteristics of driver's reaction and brake operation are investigated with risk evaluation indices concerning rear-end collision. The result shows that driver's inappropriate SA and behavior can be observed both before and after the initiation of the brake operation. Therefore, it can be claimed that a driver assistance system should continue to monitor the driver behavior even after the initiation of the brake operation because driver's inappropriate behavior tends to occur during brake operation. On the basis of the analyses, the paper proposes a framework of diagnosis of driver's behavior and discusses the design of a driver assistance system to avoid a rear-end collision.
