Traffic Signs in Complex Visual Environments

  title={Traffic Signs in Complex Visual Environments},
  author={Douglas J Mace and Kenneth Perchonok and L Pollack},
The effects of sign luminance on detection and recognition of traffic control devices is mediated through contrast with the immediate surround. Additionally, complex visual scenes are known to degrade visual performance with targets well above visual threshold. A laboratory study was conducted to determine ways of measuring visual complexity and to assess the capability of changes in sign luminance to offset decrements in performance resulting from added complexity. Positive results were found… CONTINUE READING
