Outline
To clarify the limitations and development direction of the research on Collaborative Intersection Collision Warning (CICW), CICW research progress was reviewed systematically. Firstly, the advantages and disadvantages of the existing intersection traffic conflict detection methods were analyzed. Secondly, the applicability of different warning levels, mechanisms, and modes was summarized. Thirdly, the effectiveness and safety evaluation indexes of CICW were identified, and a comparison was made between simulation, real vehicle and virtual-real fusion testing. Then, the influence of driver uncertainty and unreliable communication on CICW and its optimization were analyzed. Finally, the future development direction of CICW was prospected. The results show that the traffic risk field model presents a feasible solution to solve the comprehensive characterization of risk and conflict severity in the existing CICW conflict detection methods. However, further research is needed to establish appropriate environmental parameters, risk indicators, and determination. Moreover, modeling, forecasting, and online identification of driver’s behavior in CICW application scenarios and the adaptive construction of CICW warning modes offer viable solutions to designing reliable and effective CICW applications. Achieving a comprehensive objective evaluation of CICW in all aspects depends on the research and establishment of a comprehensive evaluation mechanism and a large-scale experimental platform. The unreliable Internet Of Vehicle (IOV) communication seriously affects the effectiveness of CICW, so it is necessary to further study the channel congestion control mechanism and CICW fault-tolerant mechanism based on communication failure/failure prediction.
