Summary
This document is a peer review report evaluating a research paper titled "Can Human Drivers and Connected Autonomous Vehicles Co-exist in Lane-Free Traffic? A Microscopic Simulation Perspective." The review, conducted by A. S.M. Bakibillah from the Tokyo Institute of Technology, assesses the methodological rigor, clarity, and contribution of the original study, which investigates the interaction between human-driven vehicles (HDVs) and connected autonomous vehicles (CAVs) in lane-free traffic environments using microscopic traffic simulations. The reviewer identifies significant ambiguities in the paper’s theoretical framework and definitions. Specifically, the role of CAVs as controllers in lane-free traffic is unclear, particularly regarding the definition and function of the "PL" controller. The reviewer questions how these controllers are modified to ensure safe velocities and avoid collisions, noting that the distinction between collision avoidance with HDVs and other mechanisms is not sufficiently explained. Furthermore, the interaction dynamics between CAVs and HDVs sharing the same lane are poorly defined, with the "APL" controller remaining unexplained. The reviewer also challenges the novelty of the study, pointing out that numerous existing works address mixed traffic environments, and argues that the specific research gaps and contributions of this paper are ambiguous. Methodological concerns are raised regarding the vehicle modeling and simulation design. The reviewer questions whether lateral dynamics were adequately considered in the modeling, given the use of car-following modes for HDVs, and asks if lane-changing behaviors were included. There is also criticism regarding the control strategies employed; the reviewer finds it unclear why the authors limited their analysis to cruise control rather than Cooperative Adaptive Cruise Control (CACC), especially since the traffic environment includes CAVs. Additionally, the reviewer notes technical errors, including missing equations (specifically Equation 11) and typos, which detract from the paper’s precision. The review also critiques the presentation and results interpretation. The reviewer describes the article as excessively lengthy for a technical paper, recommending that the authors summarize their main concepts and formulations more concisely. Regarding the findings, the simulation results for mean lateral speed in Figure 5 are deemed insignificant. The reviewer further advises that the discussion section lacks proper summarization for each finding, hindering the clarity of the conclusions. Based on these substantial issues regarding clarity, methodology, and presentation, the reviewer recommends a "Major Revision" for the manuscript. The review declares no potential competing interests.
