ABSTRACT:
A local public information system can deliver public information to appropriate target persons in a local area at appropriate times, and make it possible for the persons to reconfirm the information once delivered, without incurring communication expenses and noise. The system includes an information delivery server and an on-board device for dedicated short-range radio communication both installed on a vehicle, a roadside device installed in the neighborhood of a road on which the vehicle is traveling; and a facility equipped with a base station server and an information output device connected to the roadside device. The vehicle with the information delivery server and the on-board device installed thereon circulates through the local area, so that public information or the like is delivered from the information delivery server to the base station server in the facility on a living quarter side through dedicated short-range radio communication between the on-board device and the roadside device.
