Evaluation of Filed Application for the Night-time Visibility Assessment System for Road
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 11
Abstract
In the case of night-time accidents with high mortality rate during a traffic accident, there is a high probability that it will occur in a section where the visibility is degraded. Therefore, KICT developed the NVASo (Nighttime Visibility Assessment System for Road) in order to easily evaluate the poor visibility of the road. NVASo is a system that converts the RGB values on image pixels to YUV and evaluates the visibility of night roads with the Y value indicating brightness. It is necessary to verify the functionality and usability in order to utilize them in actual field. The evaluation was conducted by internal researchers and external experts, and the items were set with reference to the road safety diagnosis item in Korea. As a result of the evaluation, 78 out of 115 points were satisfied with 67.8% satisfaction. In the future, we will improve the function to be able to evaluate in various road geometry conditions and various lighting conditions, and we will perform the basic research on monitoring for comparative analysis before and after using the NVASo to reduce traffic accidents, And economic feasibility study.
