초록

본 연구에서는 차량신호등용 잔여시간 표시장치에 대한 시범운영을 통해 잔여시간 제공에 따른 교통안전 측면에서 운전자의 교차로 운행 행태 분석을 진행하였다. 효과분석은 녹색 잔여시간 제공에 따른 교통안전 측면에서 평가지표인 신호 위반율, 정지선 준수율, 정지선 통과속도 및 속도 편차 등을 활용하였으며, 레이더 검지기 설치를 통해 데이터를 수집하였다. 분석 결과, 차량신호 잔여시간을 제공함에 따라 신호 위반율은 감소하였으나, 정지선 미준수율은 증가하였으며, 교차로에 진입하는 접근 속도가 높아지고, 개별 차량의 속도 편차가 증가하는 것으로 분석되었다. 차량신호등용 잔여시간 표시장치에 대한 효과분석 결과, 비용 대비 효과 및 ITS의 발전 추세 등을 고려할 때 도입에 신중할 필요가 있다.

In this study, through a pilot operation of the traffic signal countdown timer(TSCT), the driver's intersection driving behaviour was analyzed regarding traffic safety according to operating the TSCT. In terms of traffic safety, the evaluation indicators such as signal violation rate, stop-line compliance rate, stop-line passing speed and standard deviation of speed were used for the effect analysis. Data were collected using a radar detector. As a result of the study, it was confirmed that the signal violation rate decreased as the remaining time was provided. This was also confirmed by the number of red-light camera installed on the pilot operation sites. However, the rate of stop-line compliance decreased, especially at the site where the red-light cameras was installed. In addition, it was analyzed that the access speed to the intersection increased, and the standard deviation of speed also increased. As a result of the effect analysis on the operation of the TSCT, it was confirmed that there were more negative than positive factors in traffic safety. In recent years, a navigation system that can receive real-time signal information through a connected car service has been developed. Therefore, it is necessary to be careful about introducing the TSCT when considering the result of effective analysis, cost-effectiveness and ITS development trend.
