PLOS ONE

Dear Dr. Mahmoud Masoud,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

We would appreciate receiving your revised manuscript by Jan 18 2020 11:59PM. When you are ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter.

To enhance the reproducibility of your results, we recommend that if applicable you deposit your laboratory protocols in protocols.io, where a protocol can be assigned its own identifier (DOI) such that it can be cited independently in the future. For instructions see: http://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols

Please include the following items when submitting your revised manuscript:

  • A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). This letter should be uploaded as separate file and labeled 'Response to Reviewers'.
  • A marked-up copy of your manuscript that highlights changes made to the original version. This file should be uploaded as separate file and labeled 'Revised Manuscript with Track Changes'.
  • An unmarked version of your revised paper without tracked changes. This file should be uploaded as separate file and labeled 'Manuscript'.

Please note while forming your response, if your article is accepted, you may have the opportunity to make the peer review history publicly available. The record will include editor decision letters (with reviews) and your responses to reviewer comments. If eligible, we will contact you to opt in or out.

We look forward to receiving your revised manuscript.

9. L123: .,

10. L128: use abbreviated version.

11. So many existing works are listed with excess details

12. The weakness of existing works

13. Why the proposed framework is better to others.

17. Use abbreviated versions after explained. For example L 164 and many other places.

18. L224: Description of dataset is too long.

19. L 252: a noun is not a sentence.

20. How could random forest DOES NOT suffer from overfitting?

21. L 274: Have the authors proofread this script before submitting?

22. L 277: of and?

Revision 1

Response Letter for “PONE-D-19-28884”

Reviewer#1, Concern # 1: Line 18: however?

Author response: Thank you, fixed.

Reviewer#1, Concern # 2: L 30: too many specific countries.

Author response: Thank you. We reduced the number of the specific countries that we mentioned as an example of countries involved in the research and development of ITS.

Reviewer#1, Concern # 3: L 37: what do CEN, ISO, and ETST stand for?

Author response: Thank you, fixed. We replaced “The interaction between ITS components is based on several standards such as CEN[2], ISO[3], ETST [4], depending on the jurisdiction.” By “The interaction between ITS components is based on several standards developed by different organizations such as European Committee for Standardization (CEN) [2], the International Organization for Standardization (ISO) [3], the European Telecommunications Standards Institute (ETST) [4], depending on the jurisdiction.”

Reviewer#1, Concern # 4: L 46: Is it necessary to list many projects?

Author response: Thank you. To our mind, listing these projects is important to show the widespread of these projects around the world. Moreover, the interested reader can find references to these important projects.

Reviewer#1, Concern # 5: L 72: what does LIDAR stand for?

Author response: Thank you. LIDAR stands for “LIght Detection and Ranging”. We updated the paper accordingly

Reviewer#1, Concern # 6: Please keep the reference style consistent through the whole script.

Author response: Mahmoud task PLEASE CHECK

Reviewer#1, Concern # 7: L 109; state of THE art.

Author response: Thank you, fixed

Reviewer#1, Concern # 8: L 112: proposed

Author response: Thank you, fixed

Reviewer#1, Concern # 9: L121: remove,.

Author response: thank you, fixed.

Reviewer#1, Concern # 10: L128: use the abbreviated version.

Author response: Thank you, fixed. We replaced “the three raw physiological signals” by “the ECG, GSR and RR signals.”

Reviewer#1, Concern # 11: So many existing works are listed with excess details

Author response: We mentioned much-existing work with some details to show that the previous work used data modalities that are not available in our FOT.

Reviewer#1, Concern # 12: The weakness of existing works

Author response: When we described much existing work, our goal was to clarify that they used different data modalities that are not available in our case. Moreover, to the best of our knowledge, we are the first who proposed using data collected from the C-ITS and the IMU to test the independence between lane change and cooperative intelligent transportation system without using other data modalities such as videos.

Reviewer#1, Concern # 13: Why the proposed framework is better for others.

Author response: As mentioned at the end of the introduction section “The present paper is different from earlier research in that it developed a framework consisting of the following:

1- Training a lane change/lane-keeping machine learning classifier using a limited number of sensing modalities (i.e. longitudinal acceleration, lateral acceleration, roll, and yaw)

2- Overcoming the uncertainty of machine learning classifier if it classifies one data point by summing up the output probabilities of the trained classifier of the whole collected data (i.e. all data points) to construct the 2x2 contingency table.

3- Estimating the null hypothesis of the test statistic using the proposed permutation test.

This framework enables us to test the independence between the lane change and the C-ITS warning without collecting expensive data modalities such as videos to train accurate machine learning classifier. In other words, the proposed framework allows us to test the hypotheses that assume C-ITS warnings at safety-critical situation help the drivers changing lane safely compared to the drivers who do not receive C-ITS warnings.”

Reviewer#1, Concern # 14: L138: a classifier for what? Should be specific.

Author response: Thank you, fixed. A classifier for lane change/lane-keeping.

Reviewer#1, Concern # 15: L 140: hard to understand.

Author response: We replaced the word pooling by the word summing up to make the statement more clear.

Reviewer#1, Concern # 16: L 143: statement is too general.

Author response: We made it more specific “This framework enables us to test the independence between the lane change and the C-ITS warning without collecting expensive data modalities such as videos to train accurate machine learning classifier. In other words, the proposed framework allows us to test the hypotheses that assume C-ITS warnings at safety-critical situation help the drivers changing lane safely compared to the drivers who do not receive C-ITS warnings.”

Reviewer#1, Concern # 17: Use abbreviated versions after explained. For example, L 164 and many other places.

Author response: Thank you, fixed.

Reviewer#1, Concern # 18: L224: Description of dataset is too long.

Author response: Thank you, fixed. We reduced the description of the dataset

Reviewer#1, Concern # 19: L 252: a noun is not a sentence.

Author response:

Reviewer#1, Concern #20: How could a random forest DOES NOT suffer from overfitting?

Author response: Thank you. In the random forest subsection, we stated that “The most significant advantage of the RF approach is that it does not suffer from overfitting because of the Law of Large Numbers, where the error rate of RF will get smaller as more CARTs are added. By adding more CATRs, the error rate will be saturated but will never get larger no matter how many CARTs are added.”

Reviewer#1, Concern #21: L 274: Have the authors proofread this script before submitting?

Author response: Yes, thank you.

Reviewer#1, Concern #2222. L 277: of and?

Author response: thank you, fixed

Reviewer#1, Concern #23: L 284: its length?

Author response: thank you,fixed

Reviewer#1, Concern #24: L 345: dds?

Author response: thank you, fixed

Reviewer#1, Concern #25: L 510: use words rather than variables in conclusion.

Author response: thank you, fixed.
