Abstract

In this paper, we introduce a warning message providing methodology by considering the elderly's walking behavior in V2P(: Vehicle-to-Pedestrian) communication systems. Using the elderly's accident records in Kyounggi-do area from 2011 to 2014, the elderly's accident behaviors are analyzed by categorizing accidents as road type (single road/ crossing road), existence of traffic signal (with signal/ without signal), existence of crosswalk (crosswalk/ jaywalk), cause of accident (jaywalk/ signal violation/ carelessness accident/ Etc.). In addition, the elderly's behavior variable and vehicle speed are applied, then some threshold values are utilized in a warning message providing in conflict area. Finally, we propose a distance which can protect an accident depending on the elderly's walking speed, safety margin and vehicle speed. By applying the results of this research to the V2P/P2V communication based road safety message providing system with the elderly's walking behavior, it may be helpful to reduce accident rate of the elderly.

본 논문은 V2P(Vehicle to Pedestrian) 통신시스템에서 고령자의 보행 행태를 고려한 위험정보의 제공방법에 관한 연구이다. 본 연구에서는 경기도 지역의 2011년-2014년의 1219건의 노인교통사고에 대하여 도로유형(단일로, 교차로), 신호유무(무신호, 신호), 횡단보도유무(횡단보도, 무단횡단), 사고원인(무단횡단, 신호위반, 부주의사고, 기타)로 분류하여 고령자 사고의 행태를 분석하였다. 또한, 고령자의 행태변수와 차량속도변수를 검토하고, 기준치를 이용하여 상충위험정보제공에 활용하도록 하였다. 고령자의 보행속도, 안전여유값 그리고 차량의 접근속도에 따라 사고를 방지할 수 있도록 요구하는 거리를 제안한다. 본 연구의 결과물을 고령자 보행형태의 변수를 고려한 V2P 통신 및 P2V 통신 기반의 상충위험정보 제공시스템에 적용함으로써 고령자의 사고경감에 도움이 될 것으로 사료된다.
