Driver Perception & Attention
Conspicuity, memorability and priming in hazard warning signs
2004-2005
Transfund funded project |
Participants “drove” video road scenes in the driving simulator and signs were
assessed for attentional conspicuity, search conspicuity, implicit & explicit recognition, comprehension,& priming of hazards.
Found significant differences in hazard signs’ performance.

12.90% |
19.35% |
25.81% |
 38.46% |
70.97% |
Overall conspicuity of warning signs was at low levels
compared to other types of roadside signs.
Found significant priming of road hazards (faster reaction times for hazard recognition) produced by some types of hazard warnings |
41.94% |
The most reliable metrics of warning signs’ effectiveness were attentional conspicuity, search conspicuity, and static comprehension
