[Figure 9] This is a sequence diagram showing the processing of the system according to the same embodiment. [Modes for carrying out the invention]

[0033] Hereinafter, one embodiment of the present invention will be described with reference to Figures 1 to 5.

[0034] 1. First Embodiment As shown in Figure 1, the vehicle-specific traffic analysis system of this embodiment (hereinafter referred to as "System S1") has an ETC onboard unit 10 mounted on a vehicle 1 and an ETC roadside device 2 connected via DSRC communication, and the ETC roadside device 2 and a server 4 are connected via a communication network 3 (hereinafter referred to as "Network 3"). Network 3 is a wireless communication means, or a combination of a wireless communication means and a wired communication means.

[0035] In this embodiment, Vehicle 1 refers to an automobile (for example, a light vehicle, a passenger car, a bus, or a truck).

[0036] In system S1, the ETC roadside device 2 communicates with the ETC on-board unit 10 via DSRC communication to obtain vehicle identification information of vehicle 1, including setup information, and information such as the time and location of passage on highways and parking lots. The ETC roadside device 2 also obtains images of vehicle 1. The ETC roadside device 2 then transmits the traffic information (including at least one of the setup information and the captured images, as well as the time and location information of passage) to the server 4 via the network 3. If the traffic information acquired from the ETC roadside device 2 includes setup information, Server 4 generates vehicle-specific traffic analysis information using the vehicle type information included in the setup information. On the other hand, if the traffic information acquired from the ETC roadside device 2 does not include setup information, Server 4 acquires vehicle type identification information for Vehicle 1 based on the acquired captured image and generates vehicle-specific traffic analysis information using the vehicle type identification information. The vehicle-specific traffic analysis information generated by Server 4 may also be output to an external device 5 connected to Server 4.

[0037] As a result, system S1 can easily generate vehicle-specific traffic analysis information using vehicle type information included in the setup information on server 4. Furthermore, even if server 4 cannot obtain the setup information, it can generate vehicle-specific traffic analysis information using vehicle type identification information based on captured images, thus enabling stable and highly accurate vehicle-specific traffic analysis.

[0071] Vehicle type identification information 424 is vehicle type identification information of a vehicle acquired by the processing unit 41 when the traffic information acquired from the ETC roadside device 2 does not include setup information but does include a captured image, and is stored in the storage unit 42.

[0072] The vehicle passage information 425 is the passage time information and location information included in the passage information acquired by the processing unit 41 from the ETC roadside device 2, and is stored in the storage unit 42.

[0073] The vehicle-specific traffic analysis information 426 is vehicle-specific traffic analysis information generated by the processing unit 41 and stored in the storage unit 42.

[0074] The communication unit 43 is a communication means for the server 4 to communicate with the ETC roadside device 2, and supports wireless communication, etc. The communication method of the communication unit 43 is not particularly limited.

[0075] (2) Processing The following describes the flow of traffic analysis processing performed by system S1 using each program, with reference to Figure 5.

[0076] The ETC roadside device 2 is installed at the entrance and exit of roads, etc., and communicates with the ETC on-board unit 10 at each location. First, when vehicle 1 enters the vicinity of an ETC roadside device 2 installed at the entrance of a road or the like, the ETC onboard unit 10 communicates with the ETC roadside device 2 and performs a general verification process. However, this verification process is optional.

[0077] Furthermore, the processing unit 11 of the ETC on-board unit 10 communicates with the ETC roadside device 2 via the DSRC communication unit 13 and transmits vehicle identification information 122, including setup information 1221, to the ETC roadside device 2 (step S110). Other information besides the vehicle identification information 122 (such as user identification information 123) may also be transmitted to the ETC roadside device 2.

[0078] The processing unit 21 of the ETC roadside device 2 acquires vehicle identification information 122, which includes setup information 1221 (step S210).

[0079] Furthermore, the processing unit 21 acquires the time when communication with the ETC onboard unit 10 is established as passage time information (step S230).

[0080] Furthermore, if the location information of the ETC roadside device 2 is stored in the vehicle passage information 224 of the storage unit 22, the processing unit 21 acquires the location information from the storage unit 22 (step S250). If the location information of the ETC roadside device 2 is not stored in the vehicle passage information 224 of the storage unit 22, the processing unit 21 may acquire the location information from an external device, or acquire the location information by positioning using a GPS receiver (not shown) optionally provided on the ETC roadside device 2.

[0081] Furthermore, the processing unit 21 acquires the image of vehicle 1 captured by camera C (step S270).

[0082] Steps S210 to S270 may be performed simultaneously, or their order may be changed as appropriate.

[0083] The processing unit 21 transmits to the server 4 traffic information including at least one of the vehicle identification information 122 including setup information 1221 and the captured image, as well as time of passage information and location information (step S290). In other words, If the ETC roadside device 2 is controlled to not transmit setup information 1221 externally, the processing unit 21 transmits traffic information, including captured images, passage time information, and location information, to the server 4. If the ETC roadside device 2 does not control the external transmission of setup information 1221, the processing unit 21 transmits (i) traffic information including setup information 1221, passage time information and location information, or (ii) traffic information including setup information 1221, captured image, passage time information and location information to the server 4. The setup information 1221 sent to server 4 only needs to include vehicle information.

[0084] The processing unit 41 of server 4 acquires traffic information from the ETC roadside device 2 (step S310).

[0085] If the traffic information to be acquired does not include the setup information 1221, the processing unit 41 determines the type of vehicle 1 from the captured image and acquires it as vehicle type identification information (step S320). For example, the processing unit 41 analyzes the captured image and extracts the external characteristics of vehicle 1 (size, shape, height and width of the vehicle body, etc.) and the license plate to acquire vehicle type identification information. The processing unit 41 may also perform the analysis of the captured image using an image analysis AI program stored in the memory unit 42, or it may acquire vehicle type identification information via an external device such as an image analysis AI device.

[0086] Then, if the traffic information to be acquired includes setup information 1221, the processing unit 41 generates vehicle-specific traffic analysis information using the setup information 1221, the time of passage information, and the location information. If the traffic information to be acquired does not include setup information 1221, the processing unit 41 generates vehicle-specific traffic analysis information using vehicle identification information, the time of passage information, and the location information (step S330).

[0087] Furthermore, if the traffic information includes setup information 1221, captured images, passage time information, and location information, the processing unit 41 may acquire vehicle type identification information based on the captured images in step S320, compare the vehicle type information included in the setup information 1221 with the vehicle type identification information in step S330, and generate vehicle-specific traffic analysis information only if the two match.

[0088] Furthermore, when vehicle 1 enters the vicinity of ETC roadside device 2 located at the exit of a road or other area, each of the steps described above is executed again. As a result, the server 4 associates the information obtained from the entrance-side ETC roadside device 2 with the information obtained from the exit-side ETC roadside device 2.

[0089] Server 4 may optionally output the generated vehicle-specific traffic analysis information to an external device 5. Examples of external devices 5 include display devices (such as electronic billboards) and audio output devices installed on roads, and display devices within facilities.

[0090] Furthermore, the vehicle-specific traffic analysis information generated by server 4 may be transmitted to ETC roadside device 2. In this case, ETC roadside device 2 may output the vehicle-specific traffic analysis information to a connected display device, or may appropriately transmit the vehicle-specific traffic analysis information to ETC onboard unit 10 that has passed (communicated with) ETC roadside device 2. In the latter case, ETC onboard unit 10 can provide the driver of vehicle 1 with vehicle-specific traffic analysis information with minimal time lag by outputting the acquired vehicle-specific traffic analysis information from output unit 15.

[0091] Traffic analysis information by vehicle type includes, for example, the following:

[0092] Road traffic information: Information regarding traffic conditions on roads, including, for example, the following: This includes information on: cross-sectional traffic volume (the number of vehicles passing through a certain cross-section per unit time), average travel time for a section (the average time required to pass through a section), average speed in that section, area inflow / outflow volume (the number of vehicles entering and leaving a specific area), average stay time within that area, and the degree of traffic congestion and crowding. • Information regarding the detection of anomalies such as road closures due to accidents and disasters. This information is included in the alert information. Note that information regarding road closures, etc., is generated by Server 4 based on the relevant information obtained from the external device 5.

[0093] • Parking lot survey information: Analytical information for understanding the actual usage of at least one of the following: parking lots, vehicle traffic facilities, and facilities where vehicles can park or stop. For example, this includes the following information: • Usage status of the above facilities, including the number of available spaces, whether the parking lot is full or empty, the number of vehicles entering and exiting, and the level of congestion. • Information on usage trends by day of the week, time of day, or weather, as well as usage trends by purpose or region. Each piece of weather-related information is generated based on weather information acquired by server 4 from external device 5. • Average parking time and average usage time. • Repeat usage rate • Parking lot usage data linked to road traffic volume surveys before and after the construction of the above-mentioned facilities.

[0094] Parking operation information: This refers to analytical information that contributes to the operation or management of at least one of the following: parking lots, vehicle traffic facilities, and facilities where parking is permitted. For example, it includes the following information: • Information regarding the determination of whether or not a vehicle can pass through the entry / exit gate, and information regarding the opening and closing control of the gate for pre-registered vehicles. • Detection information for vehicles parked for extended periods and abandoned vehicles, and information regarding gate opening during disasters. A vehicle is determined to be a vehicle parked for extended periods if it does not pass through the ETC roadside device installed at the exit even after a certain period of time has elapsed since it passed through the ETC roadside device installed at the entrance. This detection information is generated based on predetermined conditions stored in the memory unit 42 and is included in the alert information. • Information regarding parking control when the parking lot is full and guidance when it is empty.

[0095] Parking Capacity Information: Information relating to the number of vehicles that can currently or under specified conditions park in at least one of the following: parking lots, vehicle traffic facilities, and facilities where parking is permitted. This includes capacity information categorized by use, registered area, etc., and also includes information such as determining whether a parking lot is full or empty, and estimating the number of available spaces.

[0096] In summary, with System S1, Server 4 can easily generate vehicle-specific traffic analysis information using vehicle information included in the setup information. Furthermore, even if Server 4 cannot obtain the setup information, it can generate vehicle-specific traffic analysis information using vehicle identification information based on captured images, thus enabling stable and highly accurate vehicle-specific traffic analysis.

[0097] Furthermore, system S1 can generate road traffic information in real time, such as traffic congestion information, travel time for each section, and average speed.

[0098] Furthermore, System S1 allows for accurate acquisition of parking survey information, such as the number of available spaces, occupancy status, and average parking time, for parking lots, vehicle traffic facilities, and facilities where parking and stopping are permitted.

[0099] Furthermore, System S1 can acquire parking lot operation information such as whether or not entry / exit gates can be passed and detection of long-term parking, thereby enabling efficient management and operation of the parking lot. In addition, System S1 can quickly provide the generated alert information to the driver of Vehicle 1, contributing to improved traffic safety.

[0100] Furthermore, according to system S1, server 4 transmits vehicle identification information and vehicle passage information obtained from ETC roadside device 2 to management servers such as hotels, parking lots, and other facilities. From these management servers, server 4 can obtain hotel room availability information and facility coupon information, etc., by referring to the location information of ETC roadside device 2 included in the vehicle passage information. In this case, server 4 can also perform parking reservation processing, etc., by referring to the vehicle identification information, etc.

[0101] 2. Second Embodiment The second embodiment will be described with reference to Figures 6 and 7. 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 are omitted.

[0102] In the vehicle-specific traffic analysis system of this embodiment (hereinafter referred to as "System S2"), the ETC roadside device 2 acquires a captured image of vehicle 1 and acquires vehicle type identification information based on the acquired image. The ETC roadside device 2 then transmits traffic information (including at least one of setup information and vehicle type identification information, as well as passage time information and location information) to the server 4 via the network 3. If the information acquired from the ETC roadside device 2 includes setup information, Server 4 generates vehicle-specific traffic analysis information using the vehicle type information included in that setup information. On the other hand, if the information acquired from the ETC roadside device 2 does not include setup information, Server 4 generates vehicle-specific traffic analysis information using the acquired vehicle type identification information.

[0103] (1) Composition

[0104] ETC roadside device 2 The processing unit 21 executes the ETC roadside device program 221 stored in the memory unit 22 and also functions as a means for acquiring vehicle type identification information of vehicle 1 from the captured image (vehicle type identification information acquisition means). The processing unit 21 transmits the vehicle type identification information to the server 4 instead of the captured image.

[0105] The memory unit 22 further stores vehicle type identification information acquired by the processing unit 21.

[0106] Server 4

[0107] The processing unit 41 functions as a means (traffic analysis information generation means) to generate vehicle-specific traffic analysis information using the passage time information, location information, and vehicle type information included in the setup information if the acquired traffic information includes setup information, and to generate vehicle-specific traffic analysis information using the passage time information, location information, and vehicle type identification information acquired from the ETC roadside device 2 if the acquired traffic information does not include setup information. These functions are implemented by the server program 421.

[0108] The memory unit 42 stores server programs 421, vehicle identification information 422, vehicle type identification information 424, vehicle passage information 425, and vehicle type-specific traffic analysis information 426, etc.

[0109] The vehicle type identification information 424 is vehicle type identification information included in the traffic information acquired by the processing unit 41 from the ETC roadside device 2, and is stored in the storage unit 42.

[0110] (2) Processing The following describes the flow of traffic analysis processing performed by system S2 using each program, with reference to Figure 7. Steps identical or similar to those in the first embodiment are denoted by the same reference numerals, and detailed explanations of parts other than the differences are omitted.

[0111] The processing unit 21 of the ETC roadside device 2 determines the type of vehicle 1 from the image of vehicle 1 captured by camera C and acquires the result as vehicle type identification information (step S280). The method by which the processing unit 21 acquires the vehicle type identification information of vehicle 1 may be the same as the method by which the processing unit 41 acquires the vehicle type identification information of vehicle 1 in step S320 of the first embodiment.

[0112] The processing unit 21 transmits to the server 4 at least one of the vehicle identification information 122 including setup information 1221 and vehicle type identification information, as well as traffic information including time of passage and location information (step S290). In other words, If the ETC roadside device 2 is controlled to not transmit setup information 1221 externally, the processing unit 21 transmits traffic information, including vehicle type identification information, passage time information, and location information, to the server 4. If the ETC roadside device 2 does not control the external transmission of setup information 1221, the processing unit 21 transmits (i) traffic information including setup information 1221, passage time information and location information, or (ii) traffic information including setup information 1221, vehicle type identification information, passage time information and location information to the server 4.

[0113] If the traffic information to be acquired includes setup information 1221, the processing unit 41 of server 4 generates vehicle-specific traffic analysis information using the setup information 1221, the time of passage information, and the location information. If the traffic information to be acquired does not include setup information 1221, it generates vehicle-specific traffic analysis information using the vehicle identification information, the time of passage information, and the location information acquired from the ETC roadside device 2 (step S330).

[0114] In step S330, the processing unit 41 may, if the traffic information to be acquired includes setup information 1221 and vehicle type identification information, compare the vehicle type information included in the setup information 1221 with the vehicle type identification information, and generate vehicle-specific traffic analysis information only if the two match.

[0115] Furthermore, when vehicle 1 enters the vicinity of an ETC roadside device 2 installed at an exit of a road or the like, each of the steps described above is executed again.

[0116] As described above, according to system S2, vehicle type identification information is acquired by the ETC roadside device 2, thus reducing the burden on server 4 in generating vehicle-specific traffic analysis information.

[0117] 3. Third Embodiment A third embodiment will be described with reference to Figures 8 and 9. 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 are omitted.

[0118] In the vehicle-specific traffic analysis system of this embodiment (hereinafter referred to as "System S3"), the ETC roadside device 2 acquires vehicle type identification information for vehicle 1 based on the captured image of vehicle 1. The ETC roadside device 2 then transmits traffic information (including at least one of setup information, captured image, and vehicle type identification information, as well as passage time information and location information) to the server 4 via the network 3. However, if setup information is not included, the captured image and vehicle type identification information are transmitted together. If the information acquired from the ETC roadside device 2 includes setup information, Server 4 uses the vehicle type information included in the setup information to generate vehicle-specific traffic analysis information. On the other hand, if the information acquired from the ETC roadside device 2 does not include setup information, Server 4 acquires vehicle type identification information based on the acquired captured images, compares the vehicle type identification information acquired from the ETC roadside device 2 with the vehicle type identification information acquired by Server 4, and if they match, uses the vehicle type identification information to generate vehicle-specific traffic analysis information.

[0119] (1) Composition

[0120] ETC roadside device 2 The processing unit 21 executes the ETC roadside device program 221 stored in the memory unit 22 and also functions as a means for acquiring vehicle type identification information of vehicle 1 from the captured image (vehicle type identification information acquisition means). (i) Setup Information 1221 (ii) Setup information 1221, captured images and vehicle identification information (iii) Captured images and vehicle identification information One of the above, along with the time of passage and location information, is sent to Server 4.

[0121] The memory unit 22 further stores vehicle type identification information acquired by the processing unit 21.

[0122] Server 4 The processing unit 41 executes the server program 421 and, if the traffic information acquired from the ETC roadside device 2 includes setup information, generates vehicle-specific traffic analysis information using the passage time information, location information, and vehicle type information included in the setup information. If the acquired traffic information does not include setup information, it acquires vehicle type identification information based on the captured image acquired from the ETC roadside device 2, compares the vehicle type identification information acquired from the ETC roadside device 2 with the vehicle type identification information acquired by the processing unit 41, and functions as a means (traffic analysis information generation means) to generate vehicle-specific traffic analysis information using the vehicle type identification information if they match.

[0123] Vehicle type identification information 424 is stored in the storage unit 42 when the vehicle type identification information obtained from the ETC roadside device 2 matches the vehicle type identification information obtained by the processing unit 41.

[0124] (2) Processing The following describes the flow of traffic analysis processing performed by system S3 using each program, with reference to Figure 8. Steps identical or similar to those in the first and second embodiments are denoted by the same reference numerals, and detailed explanations of parts other than the differences are omitted.

[0125] The processing unit 21 determines the type of vehicle 1 from the image of vehicle 1 captured by camera C, and acquires the result as vehicle type identification information (step S280).

[0126] The processing unit 21 transmits to the server 4 either (i) setup information 1221, (ii) setup information 1221, captured image and vehicle type identification information, or (iii) captured image and vehicle type identification information, as well as traffic information including time of passage and location information (step S290).

[0127] If the traffic information to be acquired does not include the setup information 1221, the processing unit 41 of server 4 determines the type of vehicle 1 from the captured image and acquires it as vehicle type identification information (step S320).

[0128] If the traffic information to be acquired includes setup information 1221, the processing unit 41 of server 4 generates vehicle-specific traffic analysis information using the setup information 1221, the time of passage information, and the location information. If the traffic information to be acquired does not include setup information 1221, the processing unit 41 compares the vehicle identification information acquired from the ETC roadside device 2 with the vehicle identification information acquired by the processing unit 41, and if they match, generates vehicle-specific traffic analysis information using the vehicle identification information, the time of passage information, and the location information (step S330).

[0129] Furthermore, when vehicle 1 enters the vicinity of an ETC roadside device 2 installed at an exit of a road or the like, each of the steps described above is executed again.

[0130] As described above, according to system S3, even if server 4 cannot obtain setup information, vehicle type identification information obtained by ETC roadside device 2 and vehicle type identification information obtained by server 4 are compared to generate vehicle type-specific traffic analysis information. Therefore, highly accurate and stable vehicle type-specific traffic analysis becomes possible.

[0131] 4. Variations (i) The ETC roadside device 2 may transmit user identification information to the server 4 when, for example, performing payment processing for road usage fees. In this case, the server 4 may perform payment processing for usage fees via a payment server (not shown).

In this case, highly secure communication can be achieved.

[0133] (iii) The DSRC communication unit 25 and the communication unit 26 of the ETC roadside device 2 may be configured by a single communication device. When the ETC roadside device 2 communicates with the ETC on-board unit 10, the processing unit 21 sets the communication frequency of the communication device to a frequency compatible with the DSRC communication method. This enables DSRC communication with the ETC on-board unit 10. Also, when the ETC roadside device 2 communicates with the server 4, the processing unit 21 sets the communication frequency of the communication device to a frequency compatible with wireless communication or cellular communication. This enables communication between the ETC roadside device 2 and the server 4.

[0134] (iv) Server 4 may consist of multiple information processing devices.

[0135] (v) The processing unit 41 of the server 4 may function as a means for determining whether or not a vehicle can pass through an entrance / exit gate provided at a parking lot or parking facility, based on the time of passage information, location information, and vehicle type information or vehicle type identification information (passage eligibility determination means). In this case, the processing unit 41 is configured to send the passage eligibility determination result to the entrance / exit gate.

[0136] (vi) The information used to generate vehicle-specific traffic analysis information may include information other than time of passage information, location information, and vehicle type information or vehicle type identification information. Furthermore, the information transmitted and received by the ETC onboard unit 10, the ETC roadside device 2, and the server 4 may be modified as appropriate, provided that it does not hinder the effects of the present invention.
