Speeding Behavior While Using Adaptive Cruise Control and Lane Centering
In this study, forty drivers of vehicles with adaptive cruise control (ACC) or ACC with lane centering (Pilot Assist) were observed for about 4 weeks to record instances of speeding. Drivers utilizing ACC or ACC with added lane centering were significantly more likely to speed compared to periods of manual control. Probability of speeding with ACC was 95%, ACC with lane centering was 96%, and manual driving was 77%. In addition drivers who sped with ACC or ACC and lane centering sped slightly faster than the manual control drivers. Drivers speeding with manually-controlled vehicles sped at 6.1 mph over the speed limit, ACC speeding was 7.0 mph over, and ACC with lane centering was 7.1 mph over. The authors suggest that the safety benefits of ACC systems may be partially offset by associated speeding behavior.
