Analysis of Perceptual , Cognitive, and Motoral Characteristics and their Effects on Driving Performance

운전자의 운전수행과 관련된 지각적, 인지적 특성분석 및 그 특성이 운전에 미치는 영향분석

A fixed type driving simulator is constructed with a car body, beam projector, operation software , driving scenario, and audio equipments. With the simulator, the cognitive effects of fatigue due to two hour continuous driving of a straight road is investigated . The effects of alcohol on driving performance is also studied. The braking operation and lane keeping performance due to fatigue and alcohol are investigated. Changes of vehicle motion due to these effects are verified by computer simulation.
