A Study on the Safety Performance of the Air Chamber TMA through Accident Analysis

Abstract : More recently, workers and passengers of casualties has increased by rear-end collisions of unexpected while working on the road. Recently attracted air chamber TMA mounting car accidents which occurred in 3 years, and analyzed the effect of reducing the shock absorption and protection performance and casualties. There is a risk of the vehicle AIS4 more injury of high five accidents of casualties risk, also, was the analysis that there is risk of death was avoided by the air chamber TMA and SGT. Therefore, by mounting the TMA in the rear-end accident, so you can reduce the death and casualties, it must be increased this of attach rate for road construction vehicle. Key words : Air chamber TMA(에어챔버 트럭충격흡수장치), Rear-end collision(후면충돌), Casualties risk(상해위험), SGT(트럭 후부안전장치), AIS(약식상해등급), Death and casualties(사망 및 사상자) 1. 서 론 1) 최근 10년간 총 114건의 도로보수원 안전사고가 발생하였고 이로 인한 사고피해는 부상 76명, 사망 10명으로 나타났다. 이에 관련한 교통사고는 2003년 3건에서 2012년 10건으로 증가하여 고속도로 및 일반도로 상에서 사고처리나 유지보수 작업 중에 불의의 후면추돌사고로 인하여 작업자 및 탑승객의 사상자가 발생하고 있는 실정이다.
