Abstract

In order to drive on road safely, the type of road design and construction is basically needed to optimize driver's safety and vehicle performance. Although the heavy traffic highways were built by reflecting these factors, the national highways and local roads have still taken a lot of problems. In this study, we analyzed the behavior characteristics of a vehicle according to the speed variation of the vehicle using the PC-Crash program for the traffic accidents reconfiguration at GULUN interchange located Hongcheon in Gangwon Province. the conditions outlet surface of the road for analysis were dry road surface, wet road surface and icy road surface. As a result, we identified the fact that the friction coefficient of road surface and the speed of vehicle affected to vehicle behavior characteristics of outlet shape in GULUN interchange, and showed the possibility that we can verify a problem about road design through to this simulation in advance.

차량이 도로를 안전하게 주행하기 위해서는 기본적으로 운전자의 안전과 차량의 성능을 최적화시킬 수 있는 형태의 도로설계와 시공이 필요하다. 교통량이 많은 고속도로는 이러한 요인들을 반영하여 건설하고 있으나 여전히 일반국도와 지방도의 경우는 많은 문제점을 안고 있는 경우가 많다. 따라서 본 연구에서는 강원도 홍천에 위치한 굴운교차로에서 교통사고재현을 위한 PC-Crash 프로그램을 이용하여 도로의 유출부 노면이 마른 노면, 젖은 노면, 빙판 노면일 때, 차량의 속도변화에 따른 차량의 거동특성을 분석하였다. 그 결과로 굴운교차로내 유출부의 차량거동특성에 노면상태에 따른 마찰계수와 차량속도가 영향을 미친다는 사실을 확인하였으며, 이러한 시뮬레이션을 통하여 도로설계에 대한 문제점을 사전에 검증할 수 있다는 가능성을 보여주었다.
