Distance Perception with a Camera-Based Rear Vision System in Actual Driving.

Participants drove an instrumented car equipped with conventional rearview mirrors and with a camera rear vision system. They observed the approachof an overtaking car in the alternative rear vision systems and indicatedthe last moment at which it would be safe to initiate a lane-change maneuver in front of it. Their judgments were strongly affected by the type of display used to observe the overtaking car. The longest distances were obtained with the camera-based display at unit magnification. Distances were substantially shorter with the conventional mirror and with the camera-based display at 0.5 minification. These results are consistent with results from an earlier study conducted under static conditions.
