An Extended Car-Following Model Based on Visual Angle and Electronic Throttle Effect
Round 1
Reviewer 1 Report
The authors proposed a car-following model using the angle of the electronic throttle of the preceding vehicle to aim at the study that cars can perform more precise in control and thus, traffic flow can be improved. The stability conditions are obtained through linear stability
analysis and the so-called TDGL equation and mKdV equation are
derived, as well as the relationship between the two is obtained . The numerical simulation results showed the effectiveness of the model.
Overall, the research is interesting. However, the presentation of the paper should be improved by correcting so many grammatical errors in the current version of the paper. The authors should work carefully with someone who is good at English writing to correct grammatical errors, improve expressions, and present more clearly and effectively in the descriptions of the paper. Here are some examples that the sentences are not completed or the descriptions are not clear in the paper (please carefully go through the entire paper for corrections/rewriting):
lines 109-116, line 155, line 193 ...
Please explain "n" in the Equation (1). In fact, some explanations to the Equation (2) should be moved up to the Equation (1).
At the place near line 122, the authors should state the main research purpose of the paper, then outline the structure of the paper by the following paragraph.
Add punctuations after math equations.

Reviewer 2 Report
Considering that the electronic throttle can be applied to the vehicle for accurate control, the author proposes an extended car following model based on visual angle model by supplementing the electronic throttle angle. The stability conditions of the system are obtained by linear stability analysis. Through nonlinear analysis, the TDGL equation is obtained, and then the mKdV equation is derived. Finally, the effectiveness of the model is verified by the simulation results of MATLAB software, which shows that the angle of view and electronic throttle can improve traffic stability. Relevant scholars are concerned about the topic of vehicle stability, and the research results are of reference significance. Therefore, I think this article can be published in this journal if the author carefully modifies it according to the following questions：
- What is the physical meaning corresponding to stability conditions?
- What is the ‘electronic throttle angle’? The authors should be clear in section 2.
- The chart is named incorrectly, please check and correct them.
For example:
Page 11, “Phase diagram in the headway-sensitivity for and .” needs to be corrected to “The phase diagram in the headway-sensitivity for different values of and .”
