Abstract

In Korea, traffic accidents between pedestrians and vehicles in 2015 account for 38.8% of all accidents. This study proposes a system design that can measure the risk of conflict between a vehicle and a pedestrian. Firstly the systemdetect and estimate the position, speed, and directional data of the vehicle and the pedestrian. And then it estimate the conflict point between a vehicle and a pedestrian. The risk of conflict is quantified by estimating the pedestrian safety margin (PSM), which is the time difference between the arrival of the pedestrian at the crossing point to the point of conflict and the vehicle approaching the point. In this system each data is acquired through an external monitoring based evaluation module and an individual wearing module. In the future, such a system can be used for decision making such as the design of road hazard improvement facilities and the designation of the elderly protection area.

우리나라 2015년 차량과 보행자간의 교통사고는 전체 사고의 38.8%에 달한다. 본 연구는 차량과 보행자간의 상충상황에 대한 위험도를 측정할 수 있는 시스템의 설계방안을 제안한다. 1차적으로 차량과 보행자의 위치, 속도, 방향성을 검지하고 이를 간의 상충지점을 추정한다. 이후 상충지점까지의 횡단지점의 보행자의 도착과 그 지점에 접근하는 차량과의 시간 차이인 보행자안전간격(PSM, Pedestrian Safety Margin)을 추정하여 상충위험도를 정량화한다. 본 연구에서는 외부 모니터링 기반 평가모듈과 개인의 착용형 모듈을 통하여 각 데이터를 취득하고 이를 위한 하드웨어 및 소프트웨어 설계 내용을 제시하고 구현하였다. 향후 이러한 시스템은 도로의 위험도 개선시설 설계, 노인보호구역 지정 등의 의사결정에 활용될 수 있을 것으로 사료된다.
