Relations between the Perception - Reaction Time and the Phantom Phenomena on Signal Light |
| Abstract |
Phantom phenomena on the signal light was observed and change of perception-reaction time of the observer was measured. If phantom phenomena occurs, signal light perception- reaction time by the drivers is prolonged, the extent of which may disturb driving. Length of the perception-reaction time is affected by the luminance contrast between the turned-on and turned-off signals. Based on the measured results, several methods to prevent phantom phenomena were suggested. |
