Abstract

When a vehicle is running on the road, the surface conditions and environment of road by reason of insufficient road design standards is so greatly that have an effect on drivers. In particular, the road design of the past is conducted empirical and ideal judgment, but recently, the new technical development is attempted that three and four dimensional parameters is reconsidering and adjusting at the same time. In this study, we analyzed the vehicle behavior characteristics according to the change of driving speed and vertical grades on braking at the peak point of the frozen road by using a PC-crash program for traffic accident reconstruction. As a result, we were conformed the fact that the friction coefficient of road surface and the vehicle speed is affected by vehicle behavior characteristics for intersection vertical grades and were showed the feasibility of verification through a simulation in order to solve the problem of road design in advance.

자동차가 도로를 주행하는데 있어, 도로설계기준에 미흡한 노면의 상태와 도로환경은 운전자에게 큰 영향을 미친다. 특히, 과거에는 도로설계를 경험적이고 관념적인 판단으로 설계하고 수행하였으나, 최근에는 3, 4차원의 요소들을 동시에 검토하고 조정하는 새로운 기술개발이 시도되고 있다. 본 연구에서는 교통사고 재현을 위한 PC-crash 프로그램을 이용하여 빙판도로의 최고점에서 제동시 주행속도와 종단경사 변화에 따른 차량의 거동특성을 분석하였다. 그 결과로, 교차로 종단경사에 대한 차량거동특성에 노면상태에 따른 마찰계수와 차량속도가 영향을 미친다는 사실을 확인하였으며, 도로설계에 대한 문제점을 사전에 해결하기 위한 시뮬레이션을 통하여 검증의 적합성을 보여주었다.
