Reviewer 2 Report

It is judged to be a research paper that analyzed a lot of accident data and analyzed it statistically.

The analysis was performed based on lighting, weather, infrastructure condition, human factor, vehicle type, and vehicle color.

 

In accident analysis, accidents are more likely to be caused by the simultaneous action of multiple factors than by a single factor. Lighting, weather, and vehicle color may have mutual influences. First, in consideration of this aspect, the review results for each factor factor, including multicollinearity analysis for each category item used in the analysis, should be presented.

 

As a result of multicollinearity analysis, it is judged that there are mutually influencing factors that do not appear in the numerical values ​​even for variables that do not have a mutual influence. It is judged that it would be good if a qualitative review opinion on such a part would be presented together. It is judged that it can lead to good enough results if a logical review opinion is presented even for qualitative opinions.

 

The present content focuses on interpreting and presenting the results of statistical analysis. If additional content can be drawn from the result, it is also judged that this needs to be presented together. This may be the direction of facility improvement to reduce accidents. If there is no such content, it is judged that the individual parts of the present content are the same as the results of the previous study (eg, a white vehicle is glass for accident avoidance, etc.), so it is judged that supplementation is necessary.

Round 2

Reviewer 2 Report

As a result of reviewing the author's opinion and revised manuscript, it is judged that appropriate revisions and opinions have been presented to the previously presented opinions.

As suggested in the conclusion and discussion, it is judged that additional research is needed on the interaction and influence between factors that were not considered in this study. As it has already been suggested in the conclusion that such contents will be implemented in additional studies, we hope that additional studies will be conducted separately from this paper. We hope that additional research results will also be submitted in the form of a thesis so that they can be shared with other researchers.

It is judged that it is not necessary to supplement the contents any more, but it is judged that it would be better after re-examining the words and sentences for the purpose of enhancing the reader's understanding.

Finally, on the issue relating to procedure of proofreading, it has already checked by the native speaker and revisions have applied to the previous version of the manuscript in the tracked form of word document, as the editor recommended.
