Evaluation of Heavy-Vehicle Crash Warning Interfaces (DOT HS 812 191) September 2015.
This report evaluates heavy-vehicle collision warning interfaces as they pertain to auditory and visual components of forward collision warning systems. The results indicate that drivers receiving imminent collision warning alerts responded significantly quicker than drivers who did not receive alerts to potential rear-end events. Effects of muting other sources of in-cab audio were explored. Participants performed as well or even better when the other audio sources were not muted as long as the alerts were loud enough (15 dBA above in-cab noise level). If a visual component is part of the alert in the instrument panel, data suggests that it may be more effective if presented as an information component, not as the main alert component. This will assist drivers to look at the forward roadway as their first reactions instead of getting drawn to the visual component first. Data also suggests the auditory component should be the main alerting component in order to elicit the drivers looking to the forward roadway as their first reactions. This result was found to be true in both a truck-trailer combination units and motorcoaches. It should be noted that haptic alerts were not considered in this study.
