In Japan, the practical use of Cooperative Driving Safety Supp ort Systems (DSSS) and ITS Spot Service as V2I technology was the first of its kind in the world. The global community is not only making efforts to implement this V2 I technology, but also carrying out demonstration tests to realize V2X connectivity technology. On the other hand, big data processing, security measures, and AI technology such as deep learning are becoming the new core of connectivity technology for autonomous driving systems. The world's efforts to realize new values and services will be introduced here. Among them, I will introduce examples of cases where the car probe data of private companies are aggregated and utilized as road traffic information during times of disaster.
