Influencing Factors of Human Errors in Metro Construction Based on Structural Equation Modeling (SEM)
and Caiyun Cui 3,*
Round 1
Reviewer 1 Report
The authors analyzed the influencing factors of human error in Chinese metro construction industry and provided some valuable conclusions. However, there are some points that need to be solved suitably as follows.
1.The sentences in line 40-43 and line 214 need to be referenced.
2. The sentence in line 70-72 is not correct. Actually, quantitative studies on human errors are numerous.
3.In table 1, the factor self-efficacy should belong to mental factors rather than technical factors.
4.In the part of literature review, the research gap or value of this study was not listed clearly. Please add it.
5.In the part of hypothesis, the referred words and conclusions of some references are not correctly stated, such as “mental capital” and the conclusion in line 131. Please revise them.
6.The statement of the sentence in line 147 is not accurate. Physiological condition has an positive effect on reducing human errors rather than on human errors.
7.Some words are confusing, such as human causal errors, human-caused errors. They should be replaced with more normal words, such as human errors. Please check the paper thoroughly and revise them.
8.The words used in H5b and H5c (such as individual skills, safety climate) in lines 182-185 are not consistent with those in Figure 1. the same problem also exists in H6d.
9.The research was conducted in 12 provinces, but the numbers of the valid samples surveyed from each province should be stated.
10.In table 2, the sum of the percentages for “length of service” is not equal to 1. please check and revise other percentage values in this table.
11.In figure 2, the arrow from OF to EF does not emerge in other parts of the study. Please check and revise.
12.In line 320, it is stated that A total of four new covariate relationships were added. However, there are 5 covariate relationships in Figure 3. Please check and revise.
13.The meanings of triple stars in table 3 should be noted.
14.The statement in line 369, “this study examined the insights of the two types of human errors separately”, is just confusing. Please explain the insights of which two two types of human errors. Besides, behavioral level factors do not seem to be analyzed in this study.
15.In the part of references, some journal names are abbreviated while others are not. Please keep them the same type. Besides, the author names of reference 37 seems to be wrongly spelled, please check and revise.

Reviewer 2 Report
The topic is interesting, and the content’s structure is efficient.
- In the introduction, the authors should illustrate the safety issues in metro construction and then illustrate the human error.
- how do the authors categorize the facotrs? Based on previous studies or they do factor analysis?
- The authors should mention the software used in the analysis.
- Why did the author distribute 300 questionnaires why not 200 or more than 300? should mention for previous studies about the sample size
