Reviewer 2 Report
This article is a study of a pedestrians' response to automated vehicle.
The article is well structured: it is well introduced, the method is clearly described and the experimental design is appropriate, although it exists some cultural biases, and biases due to the type of scenario used in the study.
As this limitation is honestly endorsed by the author, I believe this article is good.

Reviewer 3 Report
A video-based eye-tracking experiment was conducted to investigate the effect of eHMI modalities, locations and other factors on the pedestrian-AV interaction. The study is quite comprehensive, and the presentation is clear and easy to follow. I'd like to congratulate the authors for the interesting work. Here I only have a few comments.
- Please re-organize this sentence in the abstract as it is awkward and too long for reading:
“Through a video-based eye-tracking experiment, this research investigated the effect of 6 eHMI modalities (flashing text, flashing smiley, flashing light band, sweeping pedestrian icon, sweeping arrow, and sweeping light bar) in three locations (grill, windshield, and roof of the AV) and pedestrian-related factors (e.g., gender, sensation-seeking, and traffic accident involvement).”
- Line 102, research->researches
- The pictures in Figure 1 can be improved in future studies.
- A descriptive statistics of the important dependent variables should be provided.
