Reviewer 2 Report
As the authors discover appropriately - With the development of traffic network in recent decades, the layout of the traffic detector becomes very complicated because of the complexity of traffic network structure and state.
Accordingly, the authors target in this paper monitoring the traffic network considering the traffic detector layout.
And, as the authors claim - An innovative method is put forward, which offers a new idea for optimization of the traffic detector layout. It not only provides a valuable reference for practical engineering but also provides scientific decision-making basis for traffic managers.
Furthermore, it provides practical guidance for the construction of intelligent transportation and smart city. Besides, it provides promotes the sustainable development of the city.
Further, the authors develop in this paper an optimal layout method of traffic detector based on network centrality using the complex network theory. The numerical experiments conducted based on data from the Sioux Falls network shows that the model has a practical value. The TNCM can be helpful to reduce the investment cost but also improves the monitoring revenue of the traffic network in complex scenarios, which offers a promising way of thinking for the optimization of the traffic detector layout scheme.
Besides, the authors explore and analyze limitations - TNCM does not consider the solution of multiple detectors located in a single road section in the detector failure scenario, which need to study deeply. Also, gain factor describes the influence of different factors on the link centrality, how to introduce more factors into TNCM reasonably is necessary to investigate.
The paper is well organized with clear goals.
The related approaches to the traffic detector layout and the centrality theory of complex network are explored and described.
The model is developed suitably.
The deployment results in different situations, such as static network, dynamic network and detector failure are provided.
The results are discussed and summarize the conclusions.

Thanks very much for taking time to review this manuscript. We checked the grammar and wording and made some changes.
Reviewer 3 Report
Title of the paper: Please add the word “Theory” at the end of the title.
Abstract, line 19 : Please explain what do you mean by saying “investment cost”.
Section 1, line 36: Please change the specific sentence (Europe is not a country).
Section 1: There a many cases where the meaning of a sentence is almost the same with the meaning of another sentence (e.g., lines 50 and 51, line 60 and line 66). Please try to reduce the number of these sentences.
Page 2, line 78: Please delete the word “previous”.
Page 2, line 84: Please change the sentence “……..summarize the conclusions".
Page 3, line 145: Why do you use capital letters for “Technical Route” ?
Page 4, line 166: Please use “UK” instead of “Britain”.
Page 5, Section 3 (Materials and Methods): Please insert a Data Flow Diagram describing the detailed steps followed in your research. This will be very helpful for the reader to better understand your methodology.
Page 5, line 220: Please provide a detailed justification for the sentence “In this paper, the OD matrix is optional” at this specific point of the paper.
Page 6, lines 253 and 254: Please explain what do you mean by “OD demand” ?
Please use another height for the letters “Figure” throughout the text (e.g., page 10, line 395, page 11, line 408, page 17, line 520 etc.).
Page 18: It is not so clear what do you mean by saying “….is provided for relevant departments”. Did you actually validate your method in Hefei ?
Page 18, Section 6 (Conclusions): Please clearly state the constraints and limitations of your research.
Page 18, Section 6 (Conclusions): Since you refer to “traffic detector construction cost” (line 584) please provide some indication on the real cost reduction (amount of money).
Finally, please check your paper for English grammar and syntax errors.
