Roadside-Assisted V2V Messaging for Connected Autonomous Vehicle

International audienceVehicle-to-vehicle (V2V) messaging is an indispensable tool for real-time dynamic information sharing in cooperative Intelligent Transportation Systems (ITSs). Although V2V standards are specified in the European Union, United States, and Japan, all such standards suffer from a set of common drawbacks. In this paper, we first analyze these issues and derive a problem statement. We then propose a roadside-assisted V2V messaging scheme in which roadside units construct a database of dynamic information obtained from sensors and transmit data to nearby and remote vehicles. We also design a common solution to the problem of differing regional standards by making the system independent of any specific set of standards. Finally, we analyze the potential requirements for designing a specification of roadside-assisted V2V messaging. The proposed system is designed to be technically compatible with 5G mobile edge computing
