초록

본 연구는 운전자에게 차량속도와 횡단보도 인근 보행자 존재 유무에 대한 정보를 제공하는 차량정보안내시스템의 설치 전·후에 대한 효과평가를 수행했다. 시나리오는 운전자에게 정보를 제공하지 않는 경우(S1), 차량주행속도만 제공하였을 경우(S2), 횡단보도에 보행자의 존재 유무와 차량주행속도를 모두 제공하였을 경우(S3) 등 3가지로 구성했다. 조사결과 시나리오 S1보다 운전자에게 정보를 제공하는 S2, S3에서 차량의 속도감속률이 약 0.4~0.7km 큰 것으로 나타났다. 또한 시나리오 S3에서 횡단보도 인근에 보행자가 있는 경우에 없는 경우보다 속도 감속률이 0.2km 높아 차량 속도를 더 줄이는 것으로 나타났다. 통계분석 결과에서도 시나리오 3개에 대한 평균 차량의 속도감속률에 차이가 있는 것으로 분석됐고, 보행자가 있는 경우 속도 감속률이 큰 것으로 나타났다.

This study conducted an effect evaluation before and after the installation of a vehicle information guidance system that provides drivers with information about vehicle speed and the presence or absence of pedestrians near pedestrian crossings. There are three types of scenarios: when no information is provided to the driver (S1), when only the vehicle driving speed is provided (S2), and when pedestrians are present on the pedestrian crossing and when both vehicle driving speeds are provided (S3). did. As a result of the survey, the speed reduction rate of the vehicle was found to be about 0.4~0.7km greater in S2 and S3 that provide information to the driver than in scenario S1. In addition, in the scenario S3, the speed reduction rate is 0.2km higher than that in the case where there are pedestrians near the pedestrian crossing, which further reduces the vehicle speed. Statistical analysis also showed that there was a difference in the speed reduction rate of the average vehicle for the three scenarios, and that the speed reduction rate was large in the presence of pedestrians.
