Abstract
This study, carried out in 2004 at the Traffic and Road Safety Research Laboratory, University of Waikato, assessed driver reactions to 16 road hazard warning signs of various formats. A range of measures, including attentional and search conspicuity, implicit and explicit recognition, dynamic and static comprehension, and sign priming were collected for hazard warning signs for road works, schools, slippery surfaces and curves. Conclusions are presented about the effectiveness of hazard warning signs, and the method for evaluating new and existing hazard warning signs used on New Zealand roads. (Author/publisher)
