University Campus as a Complex Pedestrian Dynamic Network: A Case Study of Walkability Patterns at Texas Tech University^†

Round 1

Reviewer 1 Report

This paper is dedicated to studying the pedestrian network in TTU through the lens of statistical mechanics. The characteristics of the network (e.g. isolation and integration) are evaluated, which reflects the accessibility and navigability of the network. The study is interesting, comprehensive, and sound. The results are clearly presented and are likely to be useful for decision-makers. Overall, I found this paper ready for publication.

We profoundly thank our referees for helping us to improve the quality of our manuscript.

Following their suggestions, the paper was thoroughly rewritten, starting from the Abstract, the new materials and formulas have been added to the text, the multiple typo corrections and editing have been done to the text, the new figures have been added, and the already existing figures have been modified to improve the visualization of the materials. All editing made to the text is highlighted in blue color.

To be specific,

• The Abstract was supplied with the list of our advancements and developed concenpts.
• In the Method section
  1. the Method introduction has been enriched by a discussion on the eigenvector centrality and future content;
  2. the relation between the eigenvector centrality and entropic pressure has been clarified;
  3. the notations for the entropic force and quantities have been changed;
  4. multiple explanations have been added throughout the text;
  5. the relation between the Ruelle-Bowen random walks and the entropic force has been clarified;
  6. the notations for the Isolation and Integration indices have been changed;
  7. the formulas for the random target access times and first-passage times have been clarified;
  8. the new figure illustrating the role of stereographic projection for the first attaining quantities have been added to the section
  9. the paragraphs concerning the average quantities and first-passage time for the random walks of different strategies have been rewritten;
  10. the subsection devoted to the Grand Canonical ensembles of infinitely long walks has been re-written from scratch.
  11. the new subsection has been added to Methods comprising the completely new material on Transportation Network Geometry Distortion under the Conditions of Traffic Noise and Fluctuating Transportation Capacity
• In the Results section
  1. the shortest paths morphology subsection has been supplied with a conclusion;
  2. Based on the new subsection on Transportation Network Geometry Distortion under the Conditions of Traffic Noise and Fluctuating Transportation Capacity, the campus morphology has been formulated as an interplay between the core and periphery of the campus spatial graph;
  3. the new figures we drawn and added to the text;
  4. the new material and figures on the relation between the predictable and unpredictable information (navigability and strive) has been added to the relevant subsection;
  5. The new figures representing energy and fugacity have been added to the last subsection

As a result, paper acquires the new sounding and profound meaning for the future research.

We thank our referees again for their invaluable help.

Reviewer 2 Report

-The abstract writing is not complete. Consider to present the research problem, objective, result, etc.
-The manuscript does not proposed a new formula. The author only study the  spatial morphology of a campus pedestrian network(CPN).
-It is not clear how the experiment was carried out. Because this journal is mathematical, mathematical modeling takes precedence over studying according to case studies.
-This manuscript is very contextual based on a case study and it's probably not easy to re-examine.
