A Study on the Psychological Field Model of Drivers in Traffic Conflict Environments

Round 1

Reviewer 1 Report

The author analyzed the mechanism of the effect of three factors on the driver's psychological field, namely road environment, driver characteristics, and conflict object. The psychological model is validated by experimental data. In general, the manuscript is logically structured and well-written, and it needs minor revision before it can be accepted.

(1)    The content of Section 2 is way too much. It is suggested that the introduction to previous work be shortened and incorporated into Section 1.

(2)    The author mentioned that "most of the current traffic safety evaluations using traffic conflict techniques are based on the principles of vehicle dynamics and kinematics." Can the author analyze and compare with the analysis results of traditional models in the form of data or graphs?

(3)    The variables in some formulas are not fully explained or misexpressed; please check carefully by the author.

(4)    In Section 7, it is recommended to describe the application of the conclusions obtained from this paper rather than to elaborate on the shortcomings of the research.

Reviewer 2 Report

Interesting article from the perspective of field force in psychological theory and field strength

In the introduction (lines 59-63), the authors claim to have developed a new method for psychological modeling of drivers. The conclusion (line 490) states, "The author used the traffic conflict technique and regression analysis method to investigate the mechanism of the influences from drivers of different temperament types on the psychological field under four traffic conflict scenarios." The new method is not mentioned in this sentence or in the entire conclusion. This requires clarification.

The literature review is relevant and based on current research findings, which are presented in detail.

The assertion that "...most of the current traffic conflict studies explore the mechanism of traffic conflict generation, evolution and application from the laws of kinematics without considering the psychological change of drivers" (lines 53 - 55) needs additional review. There are relevant studies that consider drivers' psychological conditions (e.g., Impacts of Drivers' Physiological and Psychological Characteristics on Road Traffic Safety Based on Traffic Safety Management Database, DOI 10.1088/1755-1315/638/1/012001).

For the 60 - 100 beats per minute heartbeat range of subjects specified for the method (line 215) reduce individual differences that are important to the experiment conducted? What are the bad driving habits (line 217)? This requires additional explanation. On the other hand, the methodology used to determine the drivers' temperament is well explained.

In my opinion, additional explanation in 3.3. Experimental Scenarios (line 250) is needed. Is there a reason for a reference for this particular scenario? Are those scenarios related to [57] or to the road environment?

The influence of the road environment is explained in 4.1.1. But what were the actual parameters of weather, adhesion coefficient of the road surface condition and the curvature and slope influence of the road in the experiments? For the relevance of the research conducted, perhaps the parameter of visibility in the scenarios would be of interest, as well as the room temperature during the experiment (may have an impact on heart rate and driver behavior).
