Effects of Alarm Modality and Alarm Reliability on Workload, Trust, and DrivingPerformance

摘要

As roads are getting more congested, the rate of automobile crashes due to driver error is also rising. Driving is an attentiondemanding task. The automobile industry has developed collision avoidance warning systems to increase situation awareness androadway safety. Different modalities of alarms could be used to increase drivers’ situation awareness. The current study is apreliminary analysis of the effects of alarm reliability (70% & 90%) and alarm modality (auditory & tactile) on driver performance,trust in alarms, and perceived workload. Participants (n=5) drove in a simulated environment. The results showed that drivers hadfewer collisions in the tactile condition than the auditory condition. The findings of this research can inform which alarm modality iseffective in improving driver performance and how practitioners can use this information to improve collision avoidance warningsystems to increase roadway safety.
