Abstract
An ITS vehicle-mounted device (17) sends/receives data in multi-content form. As a vehicle enters the communication area of a roadside apparatus (11), past drop-in place information is sent to the device (17) so that the driver can receive beneficial advertisement information. Places where the power of the ITS vehicle-mounted device (17) is turned off may be registered as past drop-in places contained in said past drop-in place information, and places of an idling stop may also be registered in the past drop-in place information. Highly accurate past drop-in place information can be produced by not registering when the stop time is short at a place where the power of the ITS vehicle-mounted device (17) is turned off or when a place is on the road right before an intersection as indicated by comparison with map data.
