Abstract: A driving assist system executes driving assist control for avoiding a collision with a target ahead of a vehicle. The driving assist control operates when the target exists within an assist area. A crossing target is the target crossing a roadway area ahead of the vehicle from a first side toward a second side. The assist area for the crossing target is divided into a plurality of divided assist areas including a first assist area located on the first side as viewed from the vehicle and a second assist area located on the second side as viewed from the vehicle. When the crossing target exists in the second assist area, the driving assist system decreases a control strength of the driving assist control as compared with a case where the crossing target exists in the first assist area.

Abstract: A communication server 200 acquires a request specifying a desired location for content creation from a requester terminal 310, and provides a notification of the request to an accepter terminal 300 accepting the content creation. The notification history managing unit 206 stores, as notification history, the distance from an accepter terminal to be provided with the notification to the desired recoding location and acceptance information. Upon acquisition of a new request, a request notification terminal selecting unit 203 selects a accepter terminal 300 that is likely to accept the request according to the notification history, and the request notifying unit 204 provides the selected accepter terminal 300 with the notification.
