Abstract

Expressway network which plays an important role on land transportation system, have been developing quantitatively and qualitatively with $7{\times}9$ structure. To cope with complex geometric condition, guidance lane marking has been installed to induce safer lane-changing maneuver. However, there is no standard on guidance lane marking and its effectiveness is also verified with limited scope. The major purpose of this research is to clarify its effectiveness in terms of driving safety aspect using virtual driving simulator and to suggest standard on the proper length. To carry this out, preference data from subjects was collected and lane-changing pattern within virtual driving environment was investigated. In addition, in order to quantify the level of comfort, Electroencephalogram data was collected and validated using statistical test. Finally, it is expected that this research can be used to establish standard on guidance lane marking.

국내 육상교통망의 중추적인 역할을 하는 고속도로는 $7{\times}9$ 형태로 양적, 질적 성장을 거듭하고 있다. 점차 복잡해지는 고속도로 기하구조에 대응하고자 차로유도선을 설치하여 운전자들의 보다 원활한 차로 변경을 유도하고 있으나 해당 시설의 설치기준이 부재하고, 그 효과 검증 또한 제한적으로 시행되고 있는 실정이다. 본 연구는 도로주행 시뮬레이터를 활용하여 주행안전성 측면에서 차로유도선의 효과를 재조명하고, 적정 연장 설치기준을 수립하는데 주된 초점을 맞추고 있다. 이를 위해, 피험자의 선호도를 조사하고, 가상의 주행환경에서 운전자의 차로 변경 행태를 분석하였다. 또한, 피험자가 차로변경 시 느끼는 편안함 정도를 계량화하기 위해 뇌파분석을 실시하였고, 도출된 결과에 대한 통계적 검증을 수행하였다. 본 연구는 차로유도선 설치기준 수립 시 기반자료로 활용될 것으로 기대한다.
