Information sharing is essential for autonomous driving supported by communicationsand smart traffic driven by big data. It enables the acquisition of knowledge in cooperative intelligent transport systems (C-ITS), which ultimately increases the integrity and accuracy of road environmental data and thereby improves the efficiency, safety and comfort of the traffic system. Moreover, many cloud services and applications, such as self-healing HD Maps, demand massive information sharing by means of vehicle-to-X (V2X) communications. In this paper, we review two existing frameworks for information sharing in C-ITS, which are open, standardized and commonly accepted: SENSORIS primarily targets at data sharing with and among clouds, specifically for digital maps. V2X-Messaging focuses on road safety and traffic efficiency based on ad hoc communications amongC-ITS-Stations (C-ITS-S), including vehicles, the roadside infrastructure and backends. Then, we analyze both frameworks considering various technical criteria and involved use cases. Finally, we propose a hybrid software architecture that combines both information sharing approaches and facilitates interworking between SENSORIS and V2X-Messaging in order to enhance C-ITS application.
