Driver Behavior with Passive and Active Vehicle Safety Systems

The advent and proliferation of Advanced Driver Assistance Systems (ADAS) are shifting the role of the driver from active operator to supervisor. Current research reveals a mixed picture of the benefits of these technologies. Further study focusing on driver response in the context of ADAS is needed to fully understand the complex interplay between vehicle drivers and the new technologies. In this study, the authors examined the effect of the use of two ADAS technologies (Adaptive Cruise Control (ACC) and Lane Departure Warning (LDW)) on driver vehicle control input behavior and visual behavior as subjects drove 36 laps across 3 visits on a test track. The effects of increasing driver experience across visits were also analyzed. Although there were some changes in vehicle control metrics over the 3 visits, these did not interact with ADAS condition. The use of ACC generally decreased accelerator pedal variability, and altered visual behavior such that fewer fixations were made to the road environment. By contrast, the use of LDW was associated with performance and behavior similar to that with no ADAS. Taken together, these results suggest a difference between passive and active ADAS systems on the behavior of drivers new to the use of ADAS technologies.
