THE EFFECTS OF DECREASING THE RADIUS OF CURVATURE OF CONVEX EXTERNAL REAR VIEW MIRRORS UPON DRIVERS JUDGEMENTS OF VEHICLES APPROACHING IN THE REARWARD VISUAL FIELD

Two experimental techniques are explored for laboratory investigation of the effect of reducing the radius of curvature of externally mounted rear-view mirrors, using filmed stimulus material prepared to maintain the ecological validity of the changing information display at the mirror surface. One method is concerned with the effect upon the "minimum safety margin" which drivers are prepared to leave in committing themselves to an offside lane change manoeuvre in front of a vehicle approaching from the rear. The second method is concerned with providing a continuous record of differences in the change over time in visual sensation caused by viewing the approach of a target vehicle through mirrors of different radii. The importance of distorted time-to-collision processing on the part of the observer is stressed. (Author/TRRL)
