Correlation Analysis between Young Driver Characteristics and Visual/Physiological Attributes at Expressway Exit Ramp
, Fei Chen 3 and Jianchuan Cheng 3Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe manuscript presents the results of an experiment that focuses on the correlation between young drivers' characteristics and visual and physiological characteristics at the expressway exit. It is well-written paper.
The sample is quite small, so the results are not so strong to explain, only some directions may be presented. The literature review may be extended to provide some references from Europe or USA. This analysis will not be presented in the introduction but in a different section.
The scope of the paper is not clearly analysed. Figure 1 may be deleted.
Table 4 should be explained. It is proposed a screenshot of the FOVs that analysed in each participant be presented in order for someone to understand what the authors examine.
In the conclusions, it is mentioned different factors that have a strong correlation. Based on which analysis do these results come out?

Response:
The authors are appreciative of the reviewer’s comments.
- The sample is quite small, so the results are not so strong to explain, only some directions may be presented. The literature review may be extended to provide some references from Europe or USA. This analysis will not be presented in the introduction but in a different section.
Response:
The literature review section has been added to be one separate section.
Some references have been added in Table 1:
“The effectiveness of dynamic speed feedback signs (DSFSs) as a speed reduction countermeasure is evaluated.”

“To the authors’ best knowledge, limited studies have addressed the young driver’s workload in the areas with different distances to the expressway exit. Thus, current study tends to explore the effects of visual and physiological attributes of young drivers at the expressway exit segments.”
- Table 4 should be explained. It is proposed a screenshot of the FOVs that analysed in each participant be presented in order for someone to understand what the authors examine.
Response:
More explanation has been added as follows:

Reviewer 2 Report
Comments and Suggestions for AuthorsThe currents study analyzed the correlation among the young driver and work state at expressway exit ramp. This paper is good in sense that it applied eye-trackers while performing simulation system.
Here are some comments for this study:
- It would be more interesting to summarize the findings and research gaps regarding the recent research efforts.
-Figure 1 could be presented in form of tables, including descriptive details like mean and standard deviation.
- More clarification should be added to the experimental design to be included in one new section, maybe named as “Material”.
- For figures 4-8, Please add the title name to the horizontal and vertical axis. Moreover, it would be consistent to make the fonts in such figures as the same size.
- Regarding the discussion section, some supportive reference should be cited, and more interpretation could be added to such section.

- It would be more interesting to summarize the findings and research gaps regarding the recent research efforts.
Response:
The literature review section has been created and research gaps have been added as follows:
Page 2, Ln 51-54.
“To the authors’ best knowledge, limited studies have addressed the young driver’s workload in the areas with different distances to the expressway exit. Thus, current study tends to explore the effects of visual and physiological attributes of young drivers at the expressway exit segments.”
Otherwise, the findings are summarized in Table 1.
- Figure 1 could be presented in form of tables, including descriptive details like mean and standard deviation.
Response:
Figure 1 has been deleted and following discussion is based on the gender, driving experiences, and driving mileage.
- More clarification should be added to the experimental design to be included in one new section, maybe named as “Material”.
Response:
The related section has been added as follows:
“3.2. Material
The experimental platform comprises UC-Win/Road scene modeling software, a driving simulator, a driver, an eye tracker, a biofeedback instrument, and an Ergolab human-machine environment synchronization platform. Among them, UC-Win/Road is mainly used to construct road scenes and road alignments conducive to driving fatigue. The driving simulator used in this experiment is shown in Figure 2. The instrument comprises three display panels, real car body instruments, and other parts. At the same time, the actual scene simulation system, the operation system, the sound simulation system, the vehicle dynamics simulation system, and the data recording system constitute the experimental platform. Ergolab human-machine environment synchronization (HMI) is a platform for simultaneous data collection and analysis of human-machine-environmental data. It is essential in experimental design, data collection, statistical analysis, and human behavior research.

The biofeedback instrument can collect the driver's physiological and psychological signals in the driving experiment. In this paper, an eight-channel multi-parameter biofeedback instrument is used to collect the heart rate data of the experimenter. The biofeedback instrument is small and light, so it will not cause much interference to the driver. The eye tracker model adopted is Tobii Pro Glasses2, which can obtain eye movement signals for subsequent research and analysis.”
- For figures 4-8, Please add the title name to the horizontal and vertical axis. Moreover, it would be consistent to make the fonts in such figures as the same size.
Response:
The figures 4-8 have been re-constructed.
- Regarding the discussion section, some supportive reference should be cited, and more interpretation could be added to such section.
Response:
Related discussion has been added as follows:
Page 8, Ln 215.
“This is consistent with recent studies (20).”
