THE EFFECTIVENESS OF SEQUENTIAL FLASHING LIGHTS TO DIRECT PASSENGERS TO EMERGENCY EXITS

Tests were conducted to ascertain if a floor-mounted strip of sequential flashing lights (SFL) could direct subjects to emergency exits under both normal and degraded visual conditions. The direction of egress indicated by the apparent flow or movement along the SFL strip was detected by nearly all subjects under all visual conditions. Despite perceiving the directional cue, many subjects did not initially follow the SFL, but went in the direction from which they entered. If instructed to follow the SFL, nearly all subjects did so, both quicker and with fewer errors than uninstructed subjects or control group subjects. Subjects who found an exit inoperable did not search for another exit unless previously instructed to do so.
