Abstract:

This study is the fourth in a series of four experiments exploring human factors issues associated with the introduction of cooperative adaptive cruise control (CACC). Specifically, the goals of this experiment were as follows: Assess drivers’ workloads under two different CACC following gaps (near and far); Assess drivers’ reactions to a vehicle merging in front of them under different following gaps; Assess drivers’ reactions to an emergency event that requires driver intervention to avoid collision; Determine whether preferred time gap following distance affects the first three goals.

As measured by the National Aeronautics and Space Administration Task Load Index, drivers’ perceived workloads did not vary between the cruise period and after the vehicle merge. However, workloads were significantly greater after the emergency crash event. Workloads varied based on neither assigned following distance nor preferred following distance.Those participants in driving in the assigned near distance were more likely to hover their foot over the brake during the merging event and to react faster to the emergency event. Preferred following distance did not affect performance. Throughout the study, participants’ following distance preferences did not affect performance. In other words, one’s abilities may not necessarily reflect his or her following preferences. This finding is promising for widespread implementation of CACC.
