Author Response

1. The contribution of studying the factors of collision severity lies in reducing the occurrence of traffic accidents and reducing the degree of casualties in accidents;
2. The quotation error in this article has been corrected;
3. In the literature review, the influencing factors of road collision accidents, such as traffic attributes, road characteristics and environmental conditions, are expounded;
4. In the part of literature review, it has been rewritten by adding relevant references and reducing references with weak relevance;
5. The summary, conclusion and grammar of the article are modified.

Reviewer 2 Report

-The paper writing should be significantly improved.

 

-The literature review section should be significantly improved. The citation style does not meet the journal requirement. Instead of listing the literature, the authors are suggested to summarize the research in this field in chronological order.

 

-       Some important information of the study site is missing. For example, how long is this study site? What is the AADT? How is the number of lanes? etc. These key information plays a significant role in modeling the traffic accidents.

 

-       The analysis is rough and lacks the key influencing factors.

 

 

-       With the deployment of connected and autonomous vehicles, the traffic accidents may be reduced. Some studies on this topic should be reviewed and this work should be listed as the future work. For example, see: Operation analysis of freeway mixed traffic flow based on catch-up coordination platoon. Accident Analysis & Prevention, 175, 106780. Enhancing mixed traffic flow safety via connected and autonomous vehicle trajectory planning with a reinforcement learning approach. Journal of Advanced Transportation, 2021.

Author Response

1. The literature review part has been revised according to the reviewer's requirements;
2. The road mileage and vehicle road of the study road have been explained in this paper;
3. The analysis content is supplemented;
4. In the abstract part, the influence of automatic driving technology on road traffic accidents is introduced.

Reviewer 3 Report

In the reviewed paper, the Authors presented the research on influencing factors of urban road traffic casualties through a support vector machine and a recursive feature elimination. The paper is dedicated to the analysis of the influencing factors of the degree of traffic accident casualty. The article is written a bit chaotic and requires some refinement:

- no abbreviations (like SVM-RFE) should be used in the title of the article. For better readability, it is recommended to give the full name in the title instead of abbreviations,

- there is no information in the title that the work concerns accidents "caused by vehicles moving on rainy days" - such information is available in the abstract section. This should be clarified in all places. In all places should be the same information,

- in the "abstract" section, the Authors wrote at the end as follows ... "Preventive measures are proposed given the distribution and causes of urban road traffic accidents on rainy days." ... This is a very general statement and it would be advisable at this point, briefly indicate what preventive measures the Authors propose,

- in the "keywords" section, please add the keyword "sustainable transportation",

 - the article should be carefully checked by a professional Native Speaker before publication,

- the Authors should use the paper template proposed by the Sustainability journal,

- all acronyms used the first time in the paper text, should be previously explained. As far now, we can find in the paper text acronyms without explanation, e.g. SVM, BWM, PSO, etc.,

- the Authors wrote as follows: ..." The results showed that self-sinking accidents, fishing boat accidents, and accidents occurring in autumn are prone to cause greater casualties."... Is it a mistake?

- "C5.0 algorithm model" - this algorithm should be explained,

- at the end of the Introduction section, the Authors wrote what was the main aim of the paper. It is very good, but at the end of the Introduction section, the Authors should also shortly write what was contained in each paper section,

- there is a lack of a "Literature review" section (as a second section in the paper, after the Introduction section). What is right, a short review of the scientific literature on the subject is presented in the Introduction section, but it would be easier and better to expand the Introduction section by presenting the background for the paper, and in the second section, a comprehensive, solid review of the research literature should be presented,

- in the Introduction section, there is a lack of solid presentation of the background of the paper. The Authors cover accidents and injuries in accidents in this article, but in the Introduction section, there are no ways to limit their number. The first main way is to build a safe road infrastructure, efficient monitoring, and traffic management, and conduct many information and preventive campaigns. Authors should mention these possibilities in the Introduction section, thus referring to the latest scientific literature in this field, i.e. building safe transport infrastructure - building roundabouts as elements that slow down traffic effectively - "The Comparison of Models for Follow-up Headway at Roundabouts", doi 10.1007 / 978-3-319-64084-6_2; "Safety Evaluation of Turbo-Roundabouts with and without Internal Traffic Separations Considering Autonomous Vehicles Operation", doi.org/10.3390/su13168810; "Analysis of driver behavior at roundabouts in Tokyo and the Tokyo surroundings", doi 10.1007 / 978-3-030-34069-8_17. One short paragraph in the Introduction section will be enough,

- in the subsection called "2.1. Data" the Authors wrote like follows: ..."The urban traffic accident data in this paper was selected from the traffic accident data of some sections of Jingshi Road in Jinan city "... Why the Authors not used all gathered data but "select" them? It needs further explanation,

- "Figure 1. Part of Jingshi Road" Do the Authors have written permission for further use of this map? Usually, publishing houses required during the publishing process submission written permission for using all tables/figures/graphics, etc. of the third Author. The Authors should think about it,

- in the subsection called "2.2. Feature Screening", the question is: why the Authors used only 6 features? not all?

- on the figure called "Figure 5. Distribution of traffic accident casualties of different vehicle types" the names and units of the axis "x" and axis "y" should be added. The same remark is dedicated to figure 6,

- the "4. Conclusions" is written in a very general way and should be extended by adding some detailed conclusions from the presented in the paper research.

Author Response

1. The title of the article has been revised;
2. In the summary, the preventive measures of urban road traffic accidents in rainy days have been briefly supplemented;
3. The article has been examined by English professionals;
4. The acronyms in the text have been explained;
5. ..." The results showed that self-sinking accidents, fishing boat accidents, and accidents occurring in autumn are prone to cause greater casualties."...This part has been deleted;
6. At the end of the introduction, the contents of each part of the article have been briefly explained;
7. The literature review has been rewritten;
8. In the introduction part, the background of measures to limit the degree of road accident casualties has been supplemented, such as road infrastructure, automatic driving technology and so on;
9. The data part used in the article means that Jingshi Road in a narrow sense, it has included all the data;
10. Figure 1 has been replaced with the graphic drawn by the author. There is no copyright problem;
11. The reason for using six types of features is that only six types of information are contained in the data;
12. Two charts have been modified;
13. The conclusion has been supplemented.

Finally, thank the teacher for his guidance.

Round 2

Reviewer 1 Report

The reviewer comments have been addressed, and the paper is recommended for publication conditional on that the following minor issue has been overcome.

As to the section “Policy management”, several factors influencing vehicle conflicts has been found by previous studies such as A multivariate method for evaluating safety from conflict extremes in real time, and Using traffic flow characteristics to predict real-time conflict risk: A novel method for trajectory data analysis. These relevant studies should be mentioned in this section.
