Abstract

South Korea, which has entered an aged society, is about to enter a super-aged society in 2025. With the increase of an aging population, traffic accidents by aged drivers have been settled as a social problem. Now, when Korea is facing a super-aged society to come, a study was conducted to prevent traffic accidents that occur while the elderly people are driving through a disaster prevention design. For theoretical research, this study examined the concept and necessity of disaster prevention design, the present condition of an aged society, aged drivers' physical and cognitive characteristics, and the policies related to the forms of traffic lights the elderly people see. In addition, to propose the design, this study investigated and analyzed the traffic safety forms and colors of the International Standards Organization and proposed the first and second forms of the design of traffic lights for the gradual improvement of the traffic lights based on that. The first improved design form is a plan for displaying a triangle, an arrow with a large area, and a quadrangle in the lens of the head of the existing traffic lights, and the second improved design form is a plan for introducing a new traffic light head and forming the traffic light with a bigger triangle, an arrow with a large area and a quadrangular lens. Since it has a visually clearer form than the present traffic lights, it is expected that aged drivers who have physical and cognitive characteristics due to aging can secure better visibility and conspicuity and that they can make better reflex responses than they can now, also in the change of driving environment (rain and heavy snowstorm, etc.). In addition, it is expected that this study would be a preceding study to prepare standard guidelines on traffic safety signs other than traffic lights to be prepared for the super-aged society.
