When the user enters a reservation number into the input unit 270 of the parking lot management device 200 when the reserved vehicle arrives at the reserved parking lot, the control unit 295 compares and matches the reservation number with the reservation management information D2. In this case, the access control means 220 is controlled to permit entry of the vehicle.

According to the above configuration, the user can easily reserve a parking lot using the information terminal device 400. Similar reservations may be made from a personal computer or the like connected to the Internet via the WWW server 520. When a CATV communication line is used as the communication line 300, a CATV terminal device and a television receiver are used. A similar reservation may be made by using an information terminal device constituted by a device.

According to the above configuration, the parking lot information center 5
The management information database 531 stores management information collected in detail by the parking lot management device 200 installed in each parking lot.
32 stores detailed usage information regarding the parking lot. Therefore, by providing the management information and the use information to the information terminal device 400 via the communication line 300, an environment in which the user of the parking lot can easily obtain detailed information on the parking lot is realized. Therefore, the utilization rate of the parking lot can be improved.

Further, in the above configuration, among the management information Dm collected by the parking lot information center 500, the burglar monitoring information D5, failure information D4, image information D3, vacancy information D6 and identification information Di are sent to the security maintenance company. If provided, it can be effectively used for crime prevention and maintenance work. Further, if the sales information D1 and the identification information Di of the management information Dm collected by the parking lot information center 500 are provided to the parking lot operating company, it can be effectively used for the business of sales totaling.

The “parking lot information” in the claims refers to the parking lot managing device 200, the parking lot information center 5.
00 and the information terminal device 400 correspond to information including at least one of usage information and management information communicated via the communication line 300.
