교통안전에 대한 공학심리학적 접근 = Perspective of Engineering Psychology on Traffic Safety

다국어 초록 (Multilingual Abstract)

In the present paper, two major sources of traffic accident(loss of vehicle control and speeding) were described in terms of driver's information-processing. Also, several guidelines for designing driver-aid systems such as front-to-rear-end collision warning system and in-vehicle navigation system as well as road configuration were considered based on the psychological research findings. For example, careful implementation of pictorial cues(in particular, texture gradient) can be used in designing road to prevent driver from speeding. Similarly, visual or auditory warnings can prepare the drivers for avoiding collision. Other research findings related to information-processing characteristics of drivers(i.e., visual scanning pattern, workload, ability of anticipation, mental rotation, and resource allocation) can also be applied to designing in-vehicle navigation system.

본 논문에서는 교통사고의 두 가지 주요 원인(차량 통제 상실과 과속)의 심리적 기제에 대해 살펴보고, 교통사고 방지 및 교통안전을 확보하기 위한 공학적 개입 즉, 안전 운전을 보조해 줄 수 있는 시스템 설계(도로 설계, 추돌 경고 시스템 및 항법 시스템 설계)가 어떠한 방식으로 이루어져야 하는지 기존의 심리학적 연구 결과들을 바탕으로 논의하였다. 구체적으로, 도로 설계와 관련하여 회화적 단서들에 대한 운전자의 과속 행동을 방지하는데 어떻게 적용되는지 살펴보았고, 추돌 가능 상황에서 운전자의 추돌 회피 행동을 보조해 줄 수 있는 추돌 경고 시스템의 설계 방안과 그 효과를 구체적인 연구 결과와 함께 예시하였다. 특히 자동차 항법 시스템 설계에 운전자의 시각적 주시 특성, 작업기억 부담과 예측 능력, 심적 회전, 주의 자원 할당 등에 대한 심리학적 연구 결과들이 시스템의 물리적 위치, 디스플레이의 정보량 및 정보 제시 형태를 결정하는데 어떻게 활용될 수 있는지 구체적으로 기술하였다.
