Abstract

This paper presents the analysis of the human driving behavior based on the expression as a GMDH technique focusing on the driver's collision avoidance maneuver. The driving data are collected by using the three dimensional driving simulator based on CAVE, which provides stereoscopic immersive vision. A GMDH is also introduced and applied to the measured data in order to build a mathematical model of driving behavior. From the obtained model, it is found that the longitudinal distance between cars($x_1$), the longitudinal relative velocity($x_2$) and the lateral displacement between cars($x_4$) play important roles in the collision avoidance maneuver under the 3D environments.

본 논문에서는 운전자의 충돌 회피 행동을 집중하여 GMDH 기법을 기초로 한 인간의 운전 행동 분석을 나타내고 있다. 운전 데이터는 3D 시각정보를 제공하는 CAVE 기반의 3차원 운전 시뮬레이터를 사용하여 취득하였다. 운전 행동의 수학적 모델을 구축하기 위해 GMDH를 도입하여 측정된 데이터를 GMDH에 적용하였다. 획득한 모델로부터, 3D 환경 하에서의 충돌 회피 행동에서 전후 차간 거리($x_1$), 전후 차간 상대속도 ($x_2$) 및 좌우 상대위치 ($x_4$)가 중요한 역할을 한다는 것을 알 수 있었다.
