• Abstract:
  This Innovations Deserving Exploratory Analysis (IDEA) project designed and tested a new feature of in-vehicle visual warning signals. Signals using this feature are termed "Motion Enhanced Warning Signals" (MEWS). They are necessitated by the accelerated sensory demands upon the Intelligent Transportation Systems (ITS) driver due to the technological assistance promised by ITS. The new feature is designed to optimally stimulate the visual nervous system if used in a Head-Up Display (HUD) as is widely predicted, or even in head-down applications. The new design feature employs motion in the warning signal with the result that signals are seen more quickly and more accurately. The use of this design feature should enable designers to upgrade warning signals intended for ITS applications.
