    • Useful field of view predicts driving in the presence of distracters 

      Wood, Joanne M.; Chaparro, Alex; Lacherez, Philippe; Hickson, Louise (Lippincott Williams & Wilkins, 2012-04)
      Purpose. The Useful Field of View (UFOV (R)) test has been shown to be highly effective in predicting crash risk among older adults. An important question which we examined in this study is whether this association is due ...
    • Using biological motion to enhance the conspicuity of roadway workers 

      Wood, Joanne M.; Tyrrell, Richard A.; Marszalek, Ralph P.; Lacherez, Philippe; Chaparro, Alex; Britt, Thomas W. (Elsevier Ltd., 2011-05)
      This study examined whether the conspicuity of road workers at night can be enhanced by distributing retroreflective strips across the body to present a pattern of biological motion (biomotion). Twenty visually normal ...
