Driver's Degree of Dependence on Collision Avoidance Systems 2005-01-0431

The authors performed an experiment on a collision avoidance system (CAS) by using a driving simulator. A driver is exposed to a variety of events designed with the support system. In each event, based on whether the brakes were operated, we proposed two indices, namely the alarm ignorance ratio and the fail-safe ratio, to indicate the degree of the driver's dependence on the support system. In addition, from the simplified NASA-TLX and the post-experiment interview, the driver's mental workload was measured. Based on the degree of dependence, the authors plan to design a support system that collaborates with the driver.
