Zusammenfassung:A TRAFFIC SAFETY (TS) PANEL (20) CAN BE EASILY OBSERVED WITH A TRAFFIC SIGNAL (10). MULTIPLE PIECES OF INFORMATION ARE CHANGED OVER TO BE DISPLAYED ON THE TS PANEL(20), AND A LUMINESCENT COLOR OF THE INFORMATION (SUCH AS TRAFFIC INFORMATION, TRAFFIC SLOGANS, ADVERTISEMENTS) OR A LUMINESCENT COLOR OF THE BACKGROUND OF THE INFORMATION IS ILLUMINATED IN THE SAME COLOR AS THAT OF THE TURNED-ON LIGHT OF THE SIGNAL (10), UNDER CONTROL OF A DETECTOR (21) WHICH DETECTS WHETHER EACH LAMP OF THE SIGNAL (10) IS TURNED ON OR NOT WITHOUT CHANGING AN ELECTRIC CIRCUIT OF THE SIGNAL (10). THEN MULTIPLE PIECES OF INFORMATION ARE SEQUENTIALLY CHANGED OVER WHILE SYNCHRONIZING WITH A CHANGEOVER OF A TURNED-ON COLOR IN ACCORDANCE WITH A DETECTION SIGNAL FROM THE DETECTOR (21), AND THE LUMINESCENT COLOR OF THE BACKGROUND IS CHANGED OVER TO HAVE THE SAME COLOR AS THAT OF THE LIGHT CURRENTLY TURNED ON. AS A RESULT, VARIOUS INFORMATION CAN BE DISPLAYED ON THE TS PANEL (20), AND A SIGNAL COLOR CAN BE RECOGNIZED NOT ONLY BY A SIGNAL LAMP BUT ALSO BY A DISPLAY COLOR OF THE TS PANEL (20).FIGURE 1
