“…NTT Human Informatics Laboratories is developing a real-time spatiotemporal data-management system, Axispot TM*1 [1,2], which stores data sent simultaneously from a large number of moving objects and searches the data in real time for moving objects present within a certain area at any specific time (Fig. 1).…”

To enable the obstacle-detection use case, in which vehicles approaching an obstacle (e.g., falling object) on the road are immediately notified of the obstacle, and the lane-specific congestion detection use case, in which the number of vehicles in each lane on the road is determined, it is necessary to store data sent simultaneously from a large number of connected vehicles, search the data in real time for vehicles present within a certain area (mesh area, road, parking lot, etc.) at any specific time, and determine the number of these vehicles. This article describes the real-time spatiotemporal data-management technology (Axispot TM ) that we are developing to meet these requirements.
