Abstract: The present disclosure makes it possible to effectively reduce power consumption of a roadside wireless communication apparatus. A determination means (21) determines whether a moving body exists on a roadway leading to an intersection. A control means (22) controls a transmission output of a wireless signal being output from a wireless communication apparatus (30), based on a lighting state of a traffic light installed at the intersection and a determination result of the determination means (21).

Abstract: Maintaining the detection accuracy of a mobile object(s) around a vehicle(s) and efficient information notification are both achieved. An information provision server includes: determination means for determining, based on primary information acquired from an individual one of a plurality of sensors, each of which senses a predetermined range of a road, whether or not to provide secondary information created by using the primary information acquired from the plurality of sensors to a first mobile object running on the road; information creation means for creating, if the determination means determines to provide the secondary information to the first mobile object, the secondary information by using the primary information acquired from the plurality of sensors; and transmission means for transmitting the secondary information to the first mobile object.

Abstract: An information processing system includes an event analyzer that detects an occurrence of an event on a basis of data measured by a predetermined sensor; a storage that stores a security policy that defines a user attribute allowed to access to each type of the event; and an access controller that controls whether or not an access from a user to data on which the event is occurring is permitted on a basis of the security policy.
