Traffic Signal State Broadcasting Over C-V2X Communication Technique for Autonomous Shuttle Service.

For conventional autonomous vehicle development, image detection plays an essential role in perception tasks. The more comprehensive detection scenarios to cover, the more computing power to consume. In this paper, we proposed an implementation work to demonstrate the traffic signal state broadcasting for an end-to-end autonomous shuttle service. According to the experimental result, the proposed system can significantly offload the image detection task in obtaining the traffic signal state. Additionally, the non-line-of-sight traffic signal state perception is effectively available via the C-V2X wireless communication technique to secure the safety of an end-to-end autonomous shuttle transportation service.
