Verification of Decline in the Driver’s Concentration Due to the Control of Light-emitting Equipment

This research considers measures to control speeding and slowing too rapidly of cars driving on an expressway using a real road experiment. In 2011, the authors controlled the driver’s sense of speed and other conditions by installing light-emitting devices along the shoulder of an expressway at a certain interval and controlling the patterns of light emitted at random. The effects of guiding drivers visually on an expressway using light-emitting devices have not been fully explained, but it has become clear that using visually induced self-motion perception (hereinafter “vection”) or life’s nature of moving in response to the stimulus of light (hereinafter “phototaxis”) is effective to a certain extent in controlling or recovering vehicle speed. In this research, the authors monitored the activities of drivers’ brains during driving because light emitting devices might incur an attention shift on the part of drivers, reducing their concentration toward cars ahead and causing unexpected accidents, though they are effective in guiding them visually. The authors conducted the world’s first real road experiment on an expressway using near-infrared spectroscopy (NIRS) measurement to compare brain activities observed when light-emitting devices were used and when they were not used and examined from the viewpoint of cognitive engineering and brain physiology whether the concentration of drivers during driving was lowered. This paper reports the results of the experiments.
