[0034] 1. First Embodiment Hereinafter, a first embodiment of the present invention will be described with reference to Figures 1 to 6.

[0035] As shown in Figure 1, the parking lot entry / exit management system of this embodiment (hereinafter referred to as "System S1") includes a roadside device 10 and a server 20. The roadside device 10 and the server 20 are connected via a communication network N (hereinafter referred to as "network N"). As shown in Figure 3, the server 20 is connected to the entrance / exit gate control device 30 (hereinafter referred to as "gate device 30") and the display device 40 via a network N, and is configured to enable mutual data output and acquisition with these external devices.

[0036] In system S1, the roadside device 10 acquires vehicle identification information from the ETC onboard unit 1 installed in the vehicle C entering and exiting the parking lot, and outputs it to the server 20. The roadside device 10 is preferably installed in the vicinity of the gate device 30. The server 20 compares the vehicle identification information obtained from the roadside device 10 with the vehicle identification information stored in advance. If the comparison results match, it outputs a traffic permission instruction to the gate device 30 and displays individual notification information identified from attribute information stored in association with the pre-stored vehicle identification information on the display device 40.

[0037] As a result, system S1 can appropriately perform individual management for each vehicle C entering and exiting the parking lot, and can also present individual notification information to vehicle C, i.e., to the driver, according to the attribute information associated with vehicle C.

[0038] Network N is a wireless communication method, or a combination of a wireless communication method and a wired communication method.

[0039] (1) Composition Roadside equipment 10 As shown in Figure 2, the roadside device 10 comprises a processing unit 11, a storage unit 12, a DSRC communication unit 13, a communication unit 14, an input unit 15, and an output unit 16, which are connected by a bus line. Some or all of these may be connected by other means such as wireless communication instead of a bus line.

[0040] The processing unit 11 is a device that performs various calculations and control processing, such as a CPU (Central Processing Unit) and an MPU (Micro Processing Unit). There may be multiple processing units 11.

[0041] The processing unit 11 executes the program 121 stored in the memory unit 12 and controls the DSRC communication unit 13 to obtain vehicle identification information of vehicle C from the ETC onboard unit 1 (roadside device identification information acquisition means), and also functions as a means to output the obtained vehicle identification information to the server 20 via the communication unit 14 (roadside device output means). The processing unit 11 may output information other than vehicle identification information to the server 20 along with the vehicle identification information.

[0042] Furthermore, the processing unit 11 has the function of appropriately storing (including temporary storage) information generated within the roadside device 10 and information acquired from external devices such as the server 20 in the storage unit 12.

[0043] The memory unit 12 is a device for storing information and is composed of, for example, RAM, ROM, and storage. Note that some or all of the memory unit 12 may be externally attached to the roadside device 10.

[0044] The memory unit 12 stores the program 121 and other information. Vehicle identification information acquired from the ETC onboard unit 1 is also stored in the memory unit 12 as appropriate.

[0045] Vehicle identification information includes the Wireless Call Number (a unique identification number individually assigned to each ETC onboard unit, hereinafter referred to as "WCN"). Furthermore, the vehicle identification information may also include vehicle registration information (setup information). Vehicle registration information may include information such as the vehicle number, vehicle height, vehicle width, vehicle length, vehicle maximum load capacity, vehicle weight, vehicle characteristics (type, use (private, commercial, emergency vehicle, etc.), shape, etc.), passenger capacity, engine displacement, fuel type, and chassis number, and some or all of this information may be output to the server 20.

[0046] The DSRC communication unit 13 includes an ETC antenna and is a communication means for the roadside device 10 to communicate with the ETC onboard unit 1. Its communication frequency is, for example, 5.8 GHz (active method). In system S1, it is preferable to employ a spot radio wave method to prevent interference with adjacent lanes.

[0047] The communication unit 14 is a communication means that connects the roadside device 10 to the network N to perform communication with an external device (such as a server 20). Communication may be performed via wired or wireless connection. The communication protocol is also not particularly limited.

[0048] The input unit 15 is a device that accepts input such as operations, and can be, for example, a mouse, buttons, a keyboard, a scanner, a microphone capable of voice input, or a touch panel integrated with the output unit 16. The input unit 15 may be installed inside the roadside device 10 or it may be externally attached.

[0049] The output unit 16 is a device that outputs information (including screen display, audio output, and print output), and is, for example, a display (including the touch panel mentioned above), a speaker, and a printer. The output unit 16 may be installed inside the roadside device 10 or it may be externally attached.

[0050] Server 20 The server 20 is an information processing device, and as shown in Figure 3, it comprises a processing unit 21, a storage unit 22, and a communication unit 23, which are connected by a bus line. Some or all of these may be connected by other means, such as wireless communication, instead of a bus line.

[0051] Furthermore, server 20 may consist of a single server, or it may consist of multiple server groups distributed according to function (for example, a database server, an application server, and a distributed system on a cloud environment).

[0052] The processing unit 21 is a device that performs various calculations and control processing, such as a CPU and an MPU. There may be multiple processing units 21.

[0053] The processing unit 21 executes the server parking lot entry / exit management program 221 stored in the memory unit 22, and also functions as the following means. • Information processing device identification information acquisition means: means for acquiring vehicle identification information from the roadside device 10. • Verification means: A means for verifying vehicle identification information obtained from the roadside device 10 with vehicle identification information 222 stored in the storage unit 22. • Instruction information output means: A means for outputting instruction information (control signal) for permission to pass to the gate device 30 when the result of the verification by the verification means matches. • Display instruction information output means: means for generating individual notification information based on attribute information 223 and outputting instruction information for displaying said individual notification information on the display device 40. In this specification, "generation" is not limited to generating new information, but also includes selecting specific information from multiple pieces of information, or extracting specific information from multiple pieces of information.

[0054] Furthermore, the processing unit 21 has the function of appropriately storing (including temporary storage) information generated within the server 20 and information acquired from external devices such as roadside equipment 10 in the storage unit 22.

[0055] The memory unit 22 is a device for storing information and consists of, for example, RAM, ROM, and storage. Note that some or all of the memory unit 22 may be stored in other external devices connected to the server 20 via the network N.

[0056] The memory unit 22 stores the server parking lot entry / exit management program 221, vehicle identification information 222, attribute information 223, and individual notification information 224, etc.

[0057] The vehicle identification information 222 and attribute information 223 are information that has been stored in the storage unit 22 in advance and have been acquired by the server 20 from other external devices beforehand. The vehicle identification information 222 is of the same type as the vehicle identification information obtained from the roadside device 10, but may contain different information other than the WCN. In other words, the configuration is not particularly limited as long as the processing unit 21 can perform a comparison between the WCN obtained from the roadside device 10 and the WCN included in the vehicle identification information 222.

[0058] Attribute information 223 is information associated with the WCN and includes, for example, the following information. However, attribute information 223 is not limited to these, and some of this information may be considered as attribute information 223. Attribute categories include, for example, "employee," "visitor," "purpose," "patient," "visitor," and "emergency." However, attribute categories can be set arbitrarily, and you may also set priority-based categories such as "VIP," "emergency," and "normal."

[0059] • In the case of a company parking lot Employee information: Employee's name, department, employee number, vehicle number, vehicle type, and attribute classification, etc. Visitor information: Visitor's name, affiliation, vehicle number, vehicle type, and attribute category, etc.

[0060] • In the case of a factory parking lot Usage information: Name of registered driver, affiliation, purpose of use, vehicle number, vehicle type and attribute classification, etc.

[0061] • In the case of a hospital parking lot Employee information: Employee's name, department, employee number, vehicle number, vehicle type, and attribute classification, etc. Patient information: Patient's name, medical department, vehicle number, vehicle type, and attribute category, etc. Visitor Information: Name of registered driver, name of patient being visited, vehicle license plate number, vehicle type and attribute classification, etc. Emergency information: Emergency vehicle jurisdiction, vehicle number, vehicle type and attribute classification, etc.

[0062] Furthermore, the memory unit 22 may store management information for vehicle C, including entry and exit logs such as entry record information, exit record information, entry time information, and exit time information (including frequency information) for each vehicle C that enters and exits the parking lot.

[0063] Individual notification information 224 is information generated by the processing unit 21 based on attribute information 223, and is displayed on the display device 40 for the driver of vehicle C to see. Examples of individual notification information 224 include personal identification information such as the driver's name (or employee's name), department and affiliation, as well as greetings such as "Good morning," "Let's do our best today," "Thank you for your hard work," "Welcome," and "Welcome." In other words, the individual notification information 224 is information that can be changed according to the driver's attributes, and can be said to be an individual message that the system wants to convey to the driver via the display device 40. Furthermore, the individual notification information 224 may be information directed not only to the driver, but also to passengers in vehicle C, etc.

[0064] The communication unit 23 is a communication means for the server 20 to communicate with external devices, including the roadside equipment 10, via the network N, and supports wireless communication, etc.

[0065] Gate device 30 The gate device 30 is installed at the entrance and exit of the parking lot and is a device that physically controls the passage of vehicle C. The gate device 30 includes, for example, a gate bar that blocks or opens the passage of vehicle C, and a gate control unit that controls the driving of the gate. Note that a mechanism other than a gate bar may be used as long as the entry of vehicle C can be physically controlled. Furthermore, the gate control unit is configured to drive the gate bar to allow vehicle C to pass when it receives instruction information (control signal) for passage permission from the server 20.

[0066] Display device 40 The display device 40 is, for example, a device equipped with a display such as digital signage, and is configured to display the individual notification information 224 output from the server 20 when it receives the display instruction information for the individual notification information 224. The display device 40 is installed, for example, near the gate device 30, in a position where the driver can see the display content from the driver's seat.

[0067] (2) Processing The following describes the flow of the parking lot entry and exit management process for vehicle C, as executed by system S1 according to each program, with reference to Figures 4 and 5.

[0068] Information is registered for each vehicle C by storing vehicle identification information 222 and attribute information 223 for each vehicle C in the storage unit 22 of the server 20 (step S210). The method of storing this information in the server 20 is not particularly limited; for example, it may be stored via information terminal devices installed in each department of the company.

[0069] After the information is registered, when vehicle C attempts to enter the parking lot, that is, when vehicle C approaches the gate device 30 from the entrance road, the processing unit 11 of the roadside device 10 communicates with the ETC onboard unit 1 installed in vehicle C via the DSRC communication unit 13 and obtains vehicle identification information (step S110). The processing unit 11 also outputs the obtained vehicle identification information to the server 20 via the communication unit 14 (step S120).

[0070] When the processing unit 21 of the server 20 obtains vehicle identification information from the roadside device 10 (step S220), it checks whether the obtained vehicle identification information matches the vehicle identification information 222 stored in the storage unit 22 (steps S230, S232). Then, if the results of the verification match, that is, if vehicle C is a registered vehicle (Y in step S232), the processing unit 21 outputs information to the gate device 30 granting permission to pass, opening the gate bar and making it possible for vehicle C to pass (step S240).

[0071] If, as a result of the above comparison, the two do not match, that is, if vehicle C is a vehicle whose information is not registered (hereinafter referred to as "unregistered vehicle") (N in step S232), the processing unit 21 performs an alert process, such as outputting "information that an unregistered vehicle is attempting to enter" to the administrator terminal device (not shown) (step S234).

[0072] Furthermore, the processing unit 21 reads attribute information 223 associated with the matching vehicle identification information from the storage unit 22 and generates individual notification information 224 based on predetermined conditions (step S250). In other words, for example, if attribute information 223 is "Employee (General Affairs Department, Taro Yamada)", then individual notification information 224 would include information such as "General Affairs Department, Taro Yamada, let's do our best today!" (see Figure 6). Furthermore, if attribute information 223 is "Visitor (VIP) Hanako Yamada, Senior Managing Director, A Corporation," then individual notification information 224 will include information such as "Welcome, Ms. Hanako Yamada, Senior Managing Director, A Corporation. All employees warmly welcome you."

[0073] Furthermore, if the above matching results match, the processing unit 21 may associate the "entry record information" and "entry time information" with the vehicle identification information 222 of vehicle C and store this information in the storage unit 22.

[0074] The processing unit 21 outputs instruction information for displaying the generated individual notification information 224 to the display device 40 via the communication unit 23 (step S260). Based on the acquired display instruction information, the display device 40 outputs and displays the individual notification information 224 on the display using a predetermined display method (step S180). In addition to outputting to the display, the display device 40 may also perform other forms of output, such as audio output and print output.

[0075] Furthermore, when vehicle C attempts to exit the parking lot, that is, when vehicle C approaches the gate device 30 from the exit road, steps S110 to S120 and steps S210 to S260 are executed again. Note that steps S250 and S260 may be omitted when exiting.

[0076] Furthermore, if the matching result in step S230 matches, the processing unit 21 may associate the "exit record information" and "exit time information" with the vehicle identification information of vehicle C and store this information in the storage unit 22.

[0077] The order of the above steps may be changed as appropriate.

[0078] As described above, System S1 not only opens and closes the gate device 30, but also displays individual notification information 224, which differs for each driver, on the display device 40 based on attribute information 223 (employee, visitor, contractor, VIP, etc.) associated with vehicle identification information 222. This makes it possible to implement highly hospitable entry and exit management tailored to the driver's attributes, such as displaying words of appreciation to employees and a welcome message to VIP guests.

[0079] Furthermore, since the driver can see the message directed to them (individual notification information 224), they can easily understand not only that the entry / exit process was executed without any problems, but also any individual messages.

[0080] Furthermore, with system S1, there is no need for security guards to be stationed at the gate device 30 or to verify the identity of the driver, thus significantly reducing costs such as personnel expenses.

[0081] Furthermore, since the entry and exit of vehicle C to and from the parking lot are managed in conjunction with vehicle identification information, security risks can be reduced and traceability after the fact can be ensured.

[0082] 2. Variations A modified example of system S1 will be explained using Figure 7. Note that the same reference numerals are used for components that are identical or similar to those in the above embodiment, and detailed explanations of components other than those that differ are omitted.

[0083] Server 20 In this modified example, the processing unit 21 of the server 20 also functions as the following means. • Calculation means: A means for calculating the latest number of available parking spaces for each parking zone based on information on the number of vehicles C that have entered and exited the parking lot, attribute information 223 associated with the vehicle identification information 222 of each vehicle C (hereinafter sometimes simply referred to as "attribute information of vehicle C"), and information on the maximum number of available parking spaces for each parking zone stored in the storage unit 22. Furthermore, when each vehicle C enters or leaves the parking lot, the processing unit 21 stores the entry / exit log in the storage unit 22, associating it with the vehicle identification information 222 of vehicle C.

[0084] The memory unit 22 stores a parking zone management table that defines the parking zones available to each vehicle C (parking areas available for each attribute information 223, such as "zones where employees can park" and "zones where visitors can park," etc., parking zones according to attribute classifications), and also stores "maximum number of parking spaces available information" and "latest number of parking spaces available information" for each parking zone.

[0085] The latest parking availability information is updated according to the entry and exit of vehicle C. Specifically, the processing unit 21 subtracts the number of available parking spaces in the parking zone corresponding to the attribute information 223 of vehicle C when vehicle C enters the parking lot based on the entry and exit log, and adds the number of available parking spaces in the same parking zone when vehicle C exits the parking lot, thereby updating the latest occupancy status for each parking zone, i.e., the latest parking availability information.

[0086] Then, in step S250 when vehicle C enters, the processing unit 21 generates individual notification information 224 including the latest parking capacity information by referring to the latest parking capacity information of the corresponding parking zone from the storage unit 22 based on the attribute information 223 of vehicle C, and in step S260, outputs instruction information to the display device 40 to display the individual notification information 224.

[0087] Furthermore, the individual notification information 224, which includes the latest information on the number of available parking spaces, may also include the following information: If the current number of available parking spaces in the employee parking zone is 5: "Please proceed to the employee parking space (5 spaces available)" (see Figure 7). In this case, the individual notification information 224 may include guidance information such as the location and direction of travel of the employee parking space. If the current number of available parking spaces in the employee parking zone is close to full (for example, if the current number of available parking spaces falls below a threshold): "Employee parking space full." In this case, the individual notification information 224 may also include alternative information such as "Please go to Zone B (temporary parking lot)." In this case, the processing unit 21 may also be configured to output an alert notification to an administrator terminal device or the like.

[0088] 3. Other variations The present invention is not limited to the embodiments and modifications described above, and the following modifications are possible. (i) The server 20 may be configured to output entry / exit logs and the like to an administrator terminal device in association with the vehicle identification information 222 of vehicle C. In this case, the administrator terminal device is installed in the guardhouse and management center, and is configured to display entry and exit logs acquired from the server 20 in real time on a display or other device. This allows administrators of system S1 (e.g., the company's administrative department) to remotely monitor parking lot entry and exit status.

[0089] (ii) In addition to the attribute information 223, the server 20 may set parking zones based on the "physical size (height, width, and length)" and "vehicle type (mini car, large SUV, truck, etc.)" of vehicle C. Specifically, the server 20 acquires information such as the size and shape of vehicles C entering and exiting the road from sensors such as an imaging unit (camera) and LiDAR (Light Detection and Ranging) separately installed on the roadside device 10. The processing unit 21 of the server 20 compares the attribute information 223, as well as information such as the size and shape of vehicle C obtained from the imaging unit, with the information of each parking zone, including restriction information (height limit and width limit, etc.), stored in the storage unit 22. Then, the processing unit 21 generates individual notification information 224 that guides tall vehicle C to "zone B of the flat parking lot," and individual notification information 224 that guides short vehicle C to "the second floor of the multi-story parking lot." This prevents vehicle C from being mistakenly guided to a parking zone that is physically inaccessible.

[0090] (iii) System S1 may be configured to link the entry time information and exit time information (entry and exit time information) from the entry and exit logs stored in the storage unit 22 of server 20 with an external attendance management system. For example, server 20 may output the entry and exit time information in CSV format to the management server of the attendance management system, or it may be configured to automatically reflect the employee's entry and exit time information as attendance time through data linkage via API (Application Programming Interface). This can reduce the effort and errors that employees may make when punching time cards.

[0091] (iv) System S1 may be configured to work with employee and visitor information terminals (e.g., smartphones). For example, when a vehicle C driven by an employee enters the parking lot, a notification of "entry record complete" may be sent via application software.

[0092] (v) The roadside device 10 may further include an imaging unit. The imaging unit captures images of the vehicle C showing its license plate, appearance, and direction of travel, and outputs these as image data or analysis data to the server 20. In this case, the server 20 may be configured to perform two-factor authentication using vehicle identification information, as well as vehicle number and vehicle type information identified from image data or analysis data. Furthermore, if vehicle C is an unregistered vehicle, the server 20 may be configured to output the vehicle number and vehicle type information to the administrator terminal device so that the administrator terminal device can view the video of vehicle C. This reduces the burden of visual verification on the administrator.

[0093] (vi) The storage unit 22 of the server 20 may store a list (blacklist) of vehicles that have illegally parked in the past and vehicles that should be prohibited from entering, associated with the vehicle identification information 222. Then, in step S230, the processing unit 21 of the server 20 checks whether the acquired vehicle identification information is included in the blacklist, that is, whether vehicle C is included in the blacklist and should be prohibited from entering. If the acquired vehicle identification information is included in the blacklist, the processing unit 21 may be configured to output instruction information to the display device 40 to display a warning message such as "Entry is not permitted. Please contact the management office," and to immediately output alert information of "Unauthorized vehicle detected" to the administrator terminal device.

[0094] Furthermore, in this case, the server 20 may be configured to acquire image data of vehicle C captured by an imaging unit or the like installed in the roadside device 10 from the roadside device 10, store information such as the license plate of vehicle C identified from the image data in the storage unit 22, and output this information to the administrator terminal device. This allows the administrator to take security measures such as guiding vehicle C to leave the premises at an early stage.

[0095] 4. Second Embodiment Hereinafter, a second embodiment of the present invention will be described with reference to Figures 8 to 12. Note that the same reference numerals are used for components identical or similar to those in the first embodiment, and detailed descriptions of components other than those that differ will be omitted.

[0096] In the parking lot entry / exit management system of this embodiment (hereinafter referred to as "System S2"), the server 20 is further connected to the attribute information acquisition device 50 via a network N, and is configured to enable mutual data output and acquisition with the attribute information acquisition device 50 (see Figures 8 and 9).

[0097] In system S2, the server 20 compares vehicle identification information acquired from the roadside device 10 with pre-stored vehicle identification information. If the comparison results match, it outputs a traffic permission instruction to the gate device 30 and displays individual notification information identified from attribute information stored in association with the pre-stored vehicle identification information on the display device 40. Furthermore, if the above matching results do not match at the time of entry, the server 20 separately acquires attribute information from the attribute information acquisition device 50 and records the acquired attribute information in association with the vehicle identification information.

[0098] This allows system S2 to add vehicle C, which is an unregistered vehicle, to the parking lot entry and exit management system.

[0099] (1) Composition

[0100] The processing unit 21 also functions as the following means by executing the server parking lot entry / exit management program 221 stored in the memory unit 22. • Attribute information acquisition means: A means for acquiring attribute information from the attribute information acquisition device 50 when the matching result by the matching means does not match during entry. • Recording means: A means for recording (storing) attribute information acquired from the attribute information acquisition device 50 and vehicle identification information acquired from the roadside device 10 in association with each other in the storage unit 22. In this embodiment, the instruction information output means is configured to output instruction information (control signal) for permission to pass to the gate device 30 when the attribute information acquisition means acquires attribute information from the attribute information acquisition device 50.

[0101] Furthermore, the processing unit 21 is configured to output instruction information to the attribute information acquisition device 50 to display information for acquiring attribute information if the matching result by the matching means does not match during entry.

[0102] The storage unit 22 is configured to store vehicle identification information acquired from the roadside device 10 as vehicle identification information 222, and attribute information acquired from the attribute information acquisition device 50 as attribute information 223, through the recording process of the processing unit 21.

[0103] Attribute information acquisition device 50 The attribute information acquisition device 50 is an information processing device and is installed at the entrance and exit of the parking lot. The attribute information acquisition device 50 is a device that acquires attribute information through the driver's operation, and includes, for example, an input mechanism such as a touch panel display, a keyboard, a camera, and a voice input microphone. The attribute information acquisition device 50 is configured to output the acquired attribute information to the server 20 once it has acquired it.

[0104] (2) Processing The following describes the flow of the parking lot entry and exit management process for vehicle C, as executed by system S2 according to each program, with reference to Figures 10 and 11. Note that the following description primarily focuses on the process when vehicle C is an unregistered vehicle.

[0105] When the processing unit 21 of the server 20 obtains vehicle identification information from the roadside device 10 (step S220), it checks whether the obtained vehicle identification information matches the vehicle identification information 222 stored in the storage unit 22 (steps S230, S232).

[0106] If, as a result of the above comparison, the two do not match, that is, if vehicle C is an unregistered vehicle (N in step S232), the processing unit 21 performs attribute information acquisition processing (step S270).

[0107] In other words, the processing unit 21 outputs information (registration guidance screen display information) to the attribute information acquisition device 50 for displaying a registration guidance screen in order to acquire attribute information of vehicle C, which is an unregistered vehicle. The attribute information acquisition device 50, which has obtained the registration guidance screen display information, displays the registration guidance screen on the touch panel display. As an example of the registration guidance screen, as shown in Figure 12, a message such as "This is an unregistered vehicle. Do you want to register for temporary use?" is displayed, along with buttons to select or enter attributes (employee, visitor, and business, etc.) and a name input field. When the driver operates the touch panel display to input attribute information, the attribute information acquisition device 50 outputs the input attribute information to the server 20.

[0108] The processing unit 21 of the server 20 records the attribute information acquired from the attribute information acquisition device 50 in the storage unit 22 in association with the vehicle identification information acquired from the roadside device 10 (step S280).

[0109] Furthermore, the processing unit 21 outputs instruction information granting passage permission to the gate device 30, causing the gate bar to open and making it possible for vehicle C to pass (step S240). In addition, in system S2, the generation of individual notification information 224 and its display on the display device 40 when vehicle C is an unregistered vehicle may be omitted.

[0110] Furthermore, the vehicle identification information and attribute information of vehicle C are recorded in the storage unit 22 as vehicle identification information 222 and attribute information 223, respectively, in step S280. Therefore, when exiting the road, the vehicle identification information acquired by the server 20 from the roadside device 10 will match the vehicle identification information 222 stored in the storage unit 22 (Y in step S232). In this case, the processing unit 21 will not execute step S270 and will execute from step S240 onward. However, steps S250 and S260 at the time of exiting the road may be omitted.

[0111] As described above, with system S2, even if an unregistered vehicle, such as an unexpected visitor or delivery person, approaches the gate device 30, information can be registered using the vehicle identification information and attribute information acquired on the spot. This reduces the workload for administrators and allows for the smooth integration of unregistered vehicles into the entry and exit management system.

[0112] 5. Variations (i) When the processing unit 21 of the server 20 records attribute information acquired from the attribute information acquisition device 50 and vehicle identification information acquired from the roadside device 10 in association with each other in the storage unit 22, it may be configured to record "expiration date information (information on the period during which entry and exit are permitted)" in association with these pieces of information. The expiration date information can be set as, for example, "Valid only on the day of issue," "Valid only once (for exit)," or "Valid for one week."

[0113] Furthermore, the processing unit 21 may be configured to automatically delete the vehicle identification information and attribute information of the target vehicle from the storage unit 22 when it determines that the associated recorded expiration date has expired (or that the specified number of uses have been completed). This prevents information on temporarily permitted vehicles from remaining on file for extended periods, saving data capacity and improving security.

[0114] (ii) In step S230 upon entry, the processing unit 21 may be configured to output an alert message "Unregistered vehicle detected" to the administrator terminal device. In this case, the administrator confirms that vehicle C is an unregistered vehicle using the administrator terminal device, and if they approve entry, they operate the administrator terminal device. In response, the administrator terminal device is configured to output instruction information to the gate device 30 to release the gate bar, and to output information to the server 20 instructing it to "acquire attribute information".

[0115] Server 20, having received instruction information for acquiring attribute information from the administrator terminal device, is configured to output instruction information to the attribute information acquisition device 50 for displaying information necessary for acquiring attribute information. In this case, the administrator can verify the safety of vehicle C and then release the gate bar, allowing for flexible operation such as prompting the driver to input attribute information afterward (or concurrently).

[0116] (iii) Attribute information may be obtained, for example, from information terminal devices installed in each department of the company (which also function as attribute information acquisition devices 50). Alternatively, the administrator terminal device may function as an attribute information acquisition device 50, and the administrator may input information that they have heard verbally from the driver on their behalf. Furthermore, if the display device 40 is equipped with a touch panel function, the display device 40 may also be used as an attribute information acquisition device 50, and the driver may input the information.

[0117] (iv) Attribute information may be obtained via an information terminal device carried by the driver. In other words, if vehicle C is an unregistered vehicle, the processing unit 21 of the server 20 may be configured to display a "QR code" on the display device 40 that contains predetermined URL information, as well as identification information such as vehicle identification information and session ID obtained from the roadside device 10. When the driver reads the QR code using an information terminal device, a web form for inputting attribute information is displayed on the information terminal device. Then, when the driver inputs attribute information into the web form and outputs it to the server 20, the server 20 can acquire the attribute information. This method allows for the smooth acquisition of attribute information without the need to install a dedicated attribute information acquisition device 50. Furthermore, other types of two-dimensional codes besides QR codes can be used if they can embed the required information. The same applies to the following. Furthermore, attribute information may be configured to be acquired from an information terminal device via application software.

[0118] (v) Furthermore, attribute information may be verified using a storage medium with an embedded IC chip, such as an employee ID card (e.g., an IC card). In this case, an "IC card reader" is installed as an attribute information acquisition device 50 near the gate device 30 (in a position where the driver can operate it from the driver's seat). If vehicle C is an unregistered vehicle, the server 20 does not immediately make a decision to permit or deny, for example, but instead enters a waiting state to read the storage medium.

[0119] Then, when the driver (employee) touches their employee ID card (IC card) to the attribute information acquisition device 50, the attribute information acquisition device 50 outputs the attribute information (e.g., employee information such as employee ID) read from the employee ID card to the server 20. The processing unit 21 of the server 20 refers to the storage unit 22 and determines the validity of the employee information obtained from the attribute information acquisition device 50.

[0120] Then, if the processing unit 21 determines that the employee information is valid (eligible for permission) (e.g., stored in the memory unit 22), it associates the "vehicle identification information" obtained from the roadside device 10 (or the information obtained in the corresponding lane if there are multiple lanes) with the "employee information" and records it in the memory unit 22 (e.g., by adding or overwriting the record), and outputs an instruction to the gate device 30 to permit passage (open the gate).

[0121] On the other hand, if employee information is invalid (e.g., employee information is not stored in the storage unit 22 because the employee has left the company), or if employee information is not read for a predetermined period of time, the processing unit 21 may be configured to output an alert message "Unregistered vehicle detected" to the administrator terminal device.

[0122] Furthermore, for example, if employee information stored in the memory unit 22 is associated with "information on whether or not the employee is permitted to use the parking lot of a specific facility," the processing unit 21 may be configured to output an alert message of "unregistered vehicle detected" to the administrator terminal device if, as a result of referencing the employee information obtained from the attribute information acquisition device 50 with the memory unit 22, it determines that the employee in question "is not permitted to use the parking lot of the facility."

[0123] According to a modified version of this configuration, for example, if an employee replaces a company car or personal vehicle, or even if they temporarily commute using a rental car, the association between attribute information and vehicle identification information, as well as entry permission, can be completed on the spot with a simple operation such as scanning the employee ID card. Furthermore, the same process can be applied when obtaining attribute information by reading a QR code.

[0124] (vi) The processing unit 21 of the server 20 may be configured to record information including attribute information in the storage unit 22 in advance and to issue a QR code based on said information. Specifically, employees of the company's relevant department or the visitors themselves register their visit information in advance through a web reservation system or similar. When server 20 obtains this visit information, it generates a QR code corresponding to that visit information and outputs it to a designated notification destination (e.g., the visitor's email address, or via push notification through another server). At this point, vehicle identification information is not yet registered. Then, on the day of arrival, when vehicle C approaches the gate device 30, and the server 20 obtains vehicle identification information of vehicle C via the roadside device 10 and performs a verification, if the result of the verification is a mismatch, the processing unit 21 does not immediately perform a decision on whether to permit or deny, for example, but instead enters a waiting state for reading the QR code.

[0125] In this case, when the driver holds an information terminal device displaying the QR code over the imaging unit installed in or connected to the attribute information acquisition device 50 (QR code reader), the attribute information acquisition device 50 acquires attribute information from the QR code and sends it to the server 20.

[0126] If the attribute information acquired from the attribute information acquisition device 50 matches the visitor information stored in the storage unit 22, the processing unit 21 of the server 20 records the vehicle identification information of vehicle C acquired from the roadside device 10 (or the information acquired in the corresponding lane if there are multiple lanes) in association with the visitor information in the storage unit 22, and also outputs instruction information to the gate device 30 to permit passage (open the gate).

[0127] In this modified example, the attribute information acquisition device 50 may be an imaging unit installed in the roadside device 10. In this case, by having the driver display the above QR code on the screen and placing the information terminal device on the dashboard of vehicle C, the attribute information acquisition device 50 can acquire attribute information from the above QR code.

[0128] This configuration allows for both pre-arranged visit reservations, smooth entry and exit on the day, and recording of vehicle identification numbers, even when the company's relevant department does not have access to the visitor's vehicle identification information (for example, for first-time visitors or those using rental cars / car-sharing services).

[0129] (vii) The acquisition of attribute information in the above modified example can also be applied to acquiring attribute information of vehicle C that is not equipped with an ETC onboard unit. In other words, if vehicle C is not equipped with an ETC onboard unit, the attribute information acquisition device 50 acquires attribute information such as the driver using the method described above. The attribute information acquisition device 50 also outputs the acquired attribute information to the server 20. The processing unit 21 of the server 20 records the acquired attribute information in the storage unit 22.

[0130] For example, if the attribute information is acquired by reading the QR code upon entry, the gate bar of the gate device 30 may be opened upon exit simply by having the attribute information acquisition device 50 read the QR code again. In other words, when exiting the vehicle, if the attribute information read from the QR code by the driver's operation or the like and output to the server 20 matches the attribute information stored in the storage unit 22 of the server 20, the processing unit 21 may be configured to output instruction information to the gate device 30 to open the gate bar. This makes it possible to achieve both smooth entry and exit and acquisition of attribute information for vehicles C that are not equipped with an ETC onboard unit.

[0131] (viii) In addition, when acquiring attribute information of a vehicle C that is not equipped with an ETC onboard unit, the server 20 may be configured to associate the vehicle number identified from the image data of vehicle C acquired from an imaging unit separately installed on the roadside device 10 with the acquired attribute information and record it in the storage unit 22. Furthermore, when the vehicle is exiting the vehicle, if the vehicle number identified from the image data of vehicle C acquired again from the imaging unit separately installed on the roadside device 10 matches the vehicle number stored in the storage unit 22, the processing unit 21 may be configured to output instruction information to the gate device 30 to open the gate bar. This allows for smooth entry and exit even for vehicle C, which is not equipped with an ETC device.

[0132] (ix) The variations of the first and second embodiments are interchangeable.

[0133] It should be noted that the present invention is not limited to the embodiments described above, and various modifications are possible without departing from the spirit of the invention. [Explanation of Symbols]
