Abstract

Effective installation and operations of traffic safety signs in the advance warning area is of considerable interest for safer traffic management at freeway work zones. This study evaluated the feasibility of traffic safety sign installation based on a driving simulation experiment to take drivers' responsive characteristics into consideration. Both the compliance rate for speed limit and a lane-changing safety index were used for evaluating a set of driving simulation scenarios. It was identified that providing speed limit signs to reduce speed in advance and afterward guiding lane-changing could lead to safer maneuvering of vehicles entering work zones. The outcomes of this study are expected to be useful for revising freeway work zone management policies toward crash prevention.

고속도로 공사장 교통관리구간 중 주의구간은 공사구간으로 진입하는 차량이 차로 변경을 수행해야 하는 구간으로 감속과 함께 안전한 차로변경이 가능하도록 교통안전표지가 설치되어야 한다. 본 연구에서는 주행시뮬레이션 분석을 통해 주의구간 내 운전자의 반응특성으로 고려한 교통안전표지 설치의 적정성을 평가하였다. 교통안전표지 위치 변경 및 제거를 통해 시나리오를 구성하고, 시나리오 별 교통안전표지의 설치 위치 적정성을 제한속도 순응률과 차로변경 안전도를 통해 비교 평가하였다. 분석 결과 제한속도 규제표지를 주의구간 상류부에 설치하여 공사구간 진입차량의 속도를 미리 감소키시고, 차로변경 주의표지를 주의구간 하류부에 설치하여 차로 변경을 최종적으로 유도하는 것이 운전자의 인지도 및 순응도 향상에 있어서 가장 효과적인 대안인 것으로 확인되었다. 본 연구의 결과는 향후 고속도로 공사장에서 발생하는 교통사고 예방을 위해 교통관리기준의 개정 시 유용하게 사용될 수 있을 것으로 기대된다.
