Effect of the Warning System Which Informs Traffic Light Change on Driving Behavior
Published May 23, 2012 by Society of Automotive Engineers of Japan in Japan
Because the risk of the accident was said to increase in the dilemma zone, a driving simulator experiment was conducted to evaluate the assumed system, which alerted the driver by a sound and vibration when a signal turned into yellow. It was confirmed that the warnings presented just before signal turning into yellow had an effect to inhibit signal disregards. When the adjustment of the vehicle speed was difficult, the driver's attention might concentrate on the vehicle operation, and reflex brake reactions to warning were observed. It was also revealed that most signal disregards were limited to specific drivers.
