Abstract
Recent technological advances made a vehicle more intelligent to increase safety and convenience for both drivers and passengers. Intelligent vehicle provides drivers with various driving safety warning information through audible sounds, visual displays, and tactile devices. However, elderly drivers using the advanced intelligent vehicle technology have been known to decrease the physical and cognitive ability such as hearing, eyesight, short term memory, and space perception. Therefore, serious possible age-related deficits such as hearing or eyesight should be considered to design an appropriate safety warning system. This paper presents response model for the auditory safety warning design by evaluating the impact of advancing age on response performance on vehicle safety warning alarms which are widely used for alerting driving hazards. In order to analysis the response performance among age groups: younger (20-29), middle (40-49) and older (over 60), 38 drivers were asked to drive a simulated rural road in driving simulator. It was found that the response model can be offered the response time characteristic with age groups to design for safety warning system.
