THE REACTION TIME FOR THE CHANGE FROM FLASHING TO STEADY LIGHT IN TRAFFIC SIGNALS

REAKTIONSTID FOER VAEXLINGEN MELLAN BLINKANDE OCH FAST SKEN I OLIKA TRAFIKSIGNALER.

THE REACTION TIME FOR THE CHANGE FROM FLASHING TO STEADY LIGHT IN A TRAFFIC SIGNAL WAS STUDIED IN A LABORATORY SITUATION. THE RESULTS INDICATE THAT THE SHORTEST REACTION TIMES ARE OBTAINED IF THE CHANGE IS EMPHASIZED WITH AN EXTRA LIGHT, WHICH IS LIT OR EXTINGUISHED AT THE SAME TIME AS THE SIGNAL CHANGES FROM FLASHING TO STEADY LIGHT. IF AN EXTRA LIGHT IS IMPOSSIBLE OR UNDESIRABLE FOR ANY REASON THE SHORTEST REACTION TIME FOR A SINGLE LIGHT IS OBTAINED IF ITS FLASHING FREQUENCY IS AS HIGH AS POSSIBLE AND THE LIGHT PORTION OF EACH LIGHT/DARK CYCLE IS AS SHORT AS POSSIBLE.(A)
