First Claim
1. A parking-site reservation control system comprising:
- a vehicle-mounted device for requesting usage of a parking site by a vehicle in which the vehicle-mounted device is mounted;
a plurality of roadside units each disposed alone a roadway, each roadside unit having a communication area of a predetermined size that does not overlap with adjacent roadside unit communication areas, and that defines an area for communication between the respective roadside unit and the vehicle-mounted device, the plurality of roadside units including a first roadside unit disposed on a roadway for receiving a request from the vehicle-mounted device; and
usage allocating means for receiving the request from the first roadside unit and for controlling a usage state of the parking site based on the request;
wherein said system further comprising session continuation means for continuing communication with an adjacent one of the plurality of roadside units when the vehicle-mounted unit is no longer in a communication area of the first roadside unit and communication with the first roadside unit is not yet completed.

Abstract
To enable placement of a reservation at a parking site even from a remote site, communication is performed between an overhead road device disposed above a road and a vehicle-mounted device installed on a vehicle, and placement of a reservation at a parking site is performed in an integrated control computer. The integrated control computer is connected to several parking-site control computers, obtains parking-site information indicating a state of usage of a parking site from the parking-site control computers, controls the state of usage of respective parking sites, and at a time when a reservation at a parking site has been made, transmits information thereof to the parking-site control computer designated for the reservation.
