A substantially transparent windscreen head up display includes one of light emitting particles or microstructures over a predefined region of the windscreen permitting luminescent display while permitting vision through the windscreen. A method to represent graphical images upon a transparent windscreen head up display of a vehicle describing transit of the vehicle with respect to a lane of travel includes monitoring informational inputs describing an operational environment of the vehicle. Monitoring these informational inputs includes monitoring a desired lane of travel, and monitoring a current position of the vehicle. The method further includes determining a relationship of the desired lane of travel to the current position of the vehicle, determining a graphic describing the relationship of the desired lane of travel to the current position of the vehicle, and displaying the graphic describing the relationship of the desired lane of travel to the current position of the vehicle upon the substantially transparent windscreen head up display.
