Message Prediction Method and Application Based on V2X Interactive Data Completeness

With the rapid development of V2X (Vehicle-to-Everything) technology, traffic safety under vehicle-connected communication environment has become a research hotspot. This paper focuses on how to reduce the impact of occlusion effect on the data integrity of communication node interaction, and proposes a V2X interactive data integrity evaluation index based on C-V2X (Cellular Vehicle-to-everything) technology. At the same time, an information completion mechanism based on information integrity evaluation, pipelining mechanism, is proposed to complete missing messages. Finally, SUMO and NS3 joint simulation verified the reliability of the evaluation index and the accuracy of the pipeline mechanism.
