Post-Earthquake Traffic Simulation Considering Road Traversability
Round 1
Reviewer 1 Report
This manuscript proposes a post-earthquake traffic simulation method considering road traversability. It takes into account the influence of the building collapse and fires caused by the earthquake when considering road traversability. The model is verified by the measured data. After that, an example is given to demonstrate the utilization and effect. From the results, the method can provide post-earthquake traffic conditions, and can help the evacuation and rescue decision after the earthquake. The subject of the manuscript is interesting. The reviewer’s comments are following:
1. The relationship between earthquake and fire should be discussed and analyzed. The author calculated fire quantity by Equation (3). In fact, whether the earthquake caused the fire was uncertain. Why building collapse and fires are considered simultaneously the impact range study?
2. In Section 3.1， in order to highlight the impact of building collapse and fires, the maximum effect is considered. Under this premise, whether the determined Fmax will be too large; in addition, Fmax is used to determine the traffic conditions of different roads, then what is the qualitative impact of the size of Fmax on the following results. It would be better to clarify the units of Formula (1) and (2).
3.When considering the proportion of vehicle travel among traffic travel modes k, will this value be affected and decreased before and after the earthquake?
4.Are the data in Tab.7 measured after the earthquake? If not, how could the models be verified?
5.Lines 248 and 416, “Error! Reference source not found.” Some pictures are too small to see the content clearly (figure 1, figure 5) resulting in poor reading experience.

Reviewer 2 Report
The authors proposed a post-earthquake traffic simulation method that considers road traversability. The proposed method can provide post-earthquake traffic conditions, which benefits the decision-making of post-earthquake evacuation and rescue. Overall, this study is well written and organized generally. Before recommending publication, some small issues need to improve. Details are listed as follows.
1. Can the authors explain why the model proposed by Nishino [17] was employed in this study to calculate the effective impact range of collapse debris?
2. Check the citation format in line 38, 248, 416.
3. Check the typo errors in line 373 (43 881), and in equations (5), (6), and (8).
4. Please present more clearly Table 2.
5. Table 7 should be shown in a larger scale.
6. Zoom in the legend of Figure 10 and 11.

Reviewer 3 Report
The paper proposes an approach to predict the traffic flow in a post-earthquake environment considering the collapse of buildings and fire following.
The topic looks original to me. There is a gap in knowledge in this area which is addressed by this paper.
It appears that modeling traffic flow in the aftermath of an earthquake taking into account fire-following and the collapse of buildings is a unique aspect of the work.
The formulas presented throughout the manuscript, in some cases, were not very clear for me to review. For example, Equation (5) appears to have some issues in typesetting.
In addition to the collapse of buildings, the cordon of buildings appears to be essential for decision-making in the post-earthquake environment. The authors may want to discuss more explicitly the inclusion of the cordon of buildings in the proposed model.
The conclusion seems adequate to me, addressing the central question posed by the authors.
References also seem adequate to me.
Tables and figures seem acceptable to me. Figures 10 and 11 can be improved.
