Abstract

This study was conducted to derive the traffic accident risk index through the recognition of the elderly driver's driving pattern to reduce the traffic accident rate of elderly drivers and to reflect them in the renewal and return policy of driver's license accordingly. First, the traffic accident risk index is defined by analyzing the behavioral characteristics of older drivers to derive the major factors that lead to traffic accidents. Second, we present a method to measure the traffic accident risk index from the driving pattern of the elderly through the smart-phone, the camera and the distance sensor attached to the car. Finally, we derive three thresholds by computer simulation and determine the accident risk from the measured traffic accident risk index as four steps and suggest ways to ensure safe driving of older drivers. It is required to objectively assess the driving ability of an aged driver in accordance with the proposed method, and to induce the driver to reset the driver's license renewal cycle and voluntarily return the driver's license to minimize social costs due to increased traffic accidents.

본 연구는 고령운전자의 교통사고율 감소를 위하여 고령자의 운전패턴 인식을 통해 교통사고위험지수를 도출하고 그에 따라 운전면허증의 갱신 및 반납 정책에 반영하고자 실시되었다. 먼저, 고령운전자의 행동특성을 분석하여 교통사고를 유발하는 주요요인을 도출하여 교통사고 위험지수를 정의한다. 둘째, 자동차에 부착된 카메라, 거리센서와 스마트폰을 통하여 고령자의 운전패턴으로부터 교통사고 위험지수를 측정하는 방법을 제시한다. 마지막으로 컴퓨터 시뮬레이션으로 3개의 문턱 값을 도출하여 측정된 교통사고 위험지수로부터 사고위험도를 4단계로 판별하고 고령 운전자의 안전운전을 보장하기 방안을 제시한다. 제안하는 방법에 따라 고령운전자의 운전능력을 객관적으로 평가하여 운전면허 갱신주기의 재설정 및 자진 반납을 유도함으로써, 고령운전자의 교통사고 증가로 인한 사회적 비용을 최소화하기 위한 운전면허증 관리정책 수립에 적극 활용 가능할 것이라 믿는다.
