DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The vehicles according to the present disclosure include various types of vehicles with different drive sources, such as internal combustion engine vehicles (vehicles powered only by an internal combustion engine), HEVs (Hybrid Electric Vehicles), PHEVs (Plug-in Hybrid Electric Vehicles), BEVs (Battery Electric Vehicles), and FCEVs (Fuel Cell Electric Vehicles). In a given area, a plurality of such various types of vehicles are running.

[0011] In addition, roads in a predetermined area are divided into a plurality of road links in advance. Then, the control unit of the information processing device according to the present disclosure acquires the average fuel efficiency of traveling vehicles in a first predetermined period for each road link in the predetermined area (hereinafter, sometimes referred to as "link fuel efficiency"). That is, when a plurality of vehicles travel a road link in a first predetermined period, the control unit acquires the link fuel efficiency calculated as the average fuel efficiency of the plurality of vehicles traveling on the road link. Note that the "fuel efficiency" is a value defined as the traveling distance of a vehicle per unit fuel consumption. In addition, since BEVs and FCEVs use only an electric motor as a driving source, they do not consume fuel while traveling. Therefore, BEVs and FCEVs do not need to be counted as the number of traveling vehicles when calculating the link fuel efficiency.

[0012] Here, even if the traveling vehicle is the same, the link fuel efficiency of each road link will be different depending on the condition of each road link. In other words, the link fuel efficiency will be a value corresponding to the condition of the road link. Therefore, when there is a specific road link whose link fuel efficiency in the first predetermined period is smaller than the first threshold, the control unit restricts the passage of internal combustion engine vehicles on the specific road link after the first predetermined period.

[0013] A specific road link with a link fuel efficiency smaller than the first threshold value can be determined to be a road link in a situation where the fuel efficiency of a traveling vehicle is likely to deteriorate. An internal combustion engine vehicle has the lowest fuel efficiency under the same conditions. By restricting the traffic of internal combustion engine vehicles on a specific road link, it is possible to encourage internal combustion engine vehicles to travel on road links other than the specific road link in a specified area.

[0014] According to this, after the first predetermined period, it is possible to suppress the deterioration of the fuel efficiency of an internal combustion engine vehicle traveling in a predetermined area due to the internal combustion engine vehicle traveling on the specific road link. Also, by restricting the passage of the specific road link only to internal combustion engine vehicles after the first predetermined period, it is possible to suppress the impact on the traffic situation of the vehicle 10 in the predetermined area compared to a case in which the passage of other types of vehicles is also restricted. Therefore, according to the present disclosure, it is possible to more suitably suppress the total fuel consumption of a plurality of vehicles traveling in a predetermined area.

[0015] Hereinafter, specific embodiments of the present disclosure will be described with reference to the drawings. The dimensions, materials, shapes, and relative positions of the components described in the present embodiments are not intended to limit the technical scope of the present disclosure unless otherwise specified.

[0016] First Embodiment (System Configuration) 1 is a diagram showing a schematic configuration of a control system according to this embodiment. The control system 1 is a system for controlling vehicle traffic in a predetermined area E1. The predetermined area E1 may be, for example, an administrative district such as a city, town, or village.

[0017] In the control system 1, a management server 100 is connected to a plurality of vehicles 10 traveling within a predetermined area E1 via a network N1. Here, as the network N1, for example, a WAN (Wide Area Network) that is a global public communication network such as the Internet, or a telephone communication network such as a mobile phone may be adopted. Furthermore, the plurality of vehicles 10 traveling within the predetermined area E1 include various types of vehicles with different drive sources, such as internal combustion engine vehicles, HEVs, PHEVs, BEVs, and FCEVs. In the following, when an internal combustion engine vehicle is described to be distinguished from other types of vehicles, the reference number is "10a."

[0018] In this embodiment, roads in a predetermined area E1 are divided into a plurality of road links in advance. FIG. 2 is a diagram showing a schematic diagram of a plurality of road links in the predetermined area E1. As shown in FIG. 2, a plurality of nodes (black circles) are set on roads in the predetermined area E1. A road between two nodes is set as one road link. A road link ID is assigned to each of the plurality of road links in the predetermined area E1. The road link ID is identification information for identifying the road link. It is assumed that a plurality of vehicles 10 will travel on each road link in the predetermined area E1.

[0019] The management server 100 includes a general computer. The computer that constitutes the management server 100 includes a processor 101, a communication interface (communication I / F) 102, a main memory unit 103, and an auxiliary memory unit 104.

[0020] Here, the processor 101 may be, for example, a CPU (Central Processing Unit) or a D The communication I / F 102 is an interface for performing wireless communication via the network N1 according to the same wireless communication standard as that of the communication I / F 12 of the vehicle 10. The communication I / F 102 is, for example, a local area network (LAN) interface board, or a wireless communication circuit for wireless communication. The main memory unit 103 is, for example, a random access memory (RAM). The auxiliary memory unit 104 is, for example, a read only memory (ROM), a hard disk drive (HDD), or a flash memory. The auxiliary storage unit 104 may also include a removable medium (portable recording medium). Here, the removable medium is, for example, a USB memory, an SD card, or a disc recording medium such as a CD-ROM, a DVD disc, or a Blu-ray disc.

[0021] The auxiliary storage unit 104 stores an operating system (OS), various programs, various information tables, and the like. The processor 101 loads the programs stored in the auxiliary storage unit 104 into the main storage unit 103 and executes them to realize processing for controlling the passage of a plurality of vehicles 10 within a predetermined area E1, as described below. However, some or all of the functions of the management server 100 may be realized by hardware circuits such as ASIC and FPGA. Note that the management server 100 does not necessarily have to be realized by a single physical configuration, and may be configured by a plurality of computers that cooperate with each other.

[0022] The management server 100 receives vehicle information transmitted from each vehicle 10 traveling within a predetermined area E1. Fig. 3 is a diagram showing an example of a table configuration of the vehicle information transmitted from the vehicle 10. As shown in Fig. 3, the vehicle information has a vehicle ID field, a type field, a road link ID field, and a date and time field.

[0023] In the vehicle ID field, a vehicle ID is input, which is identification information for identifying the vehicle 10 that is the transmission source of the vehicle information. In addition, in the type field, information indicating the type of the vehicle 10 is input. The type of vehicle here is a type that is distinguished by the driving source of the vehicle as described above. Therefore, in the type field, information indicating the type, such as an internal combustion engine vehicle, HEV, PHEV, BEV, or FCEV, is input.

[0024] In the road link ID field, the road link ID of the road link on which the vehicle 10 has traveled is input. Each vehicle 10 can identify the road link on which it is traveling based on the vehicle's own position information and map information of a predetermined area E1. In addition, in the date and time field, date and time information indicating the date and time when the vehicle 10 traveled the road link corresponding to the road link ID input in the road link ID field is input.

[0025] Furthermore, if the vehicle 10 is a vehicle that uses an internal combustion engine as a driving source (i.e., an internal combustion engine vehicle, an HEV, or a PHEV), the vehicle information of the vehicle 10 also includes a fuel efficiency field, as shown in FIG. 3. In the fuel efficiency field, fuel efficiency data indicating the fuel efficiency of the vehicle 10 when the vehicle 10 is traveling on a road link corresponding to the road link ID entered in the road link ID field is entered. In other words, the fuel efficiency data entered in the fuel efficiency field is data indicating the fuel efficiency calculated for each road link traveled by the vehicle 10. The fuel efficiency data is indicated by the travel distance of the vehicle 10 per unit fuel consumption. Also, a BEV and an FCEV have only an electric motor as a driving source and do not consume fuel while traveling. Therefore, if the vehicle 10 is a BEV or an FCEV, the vehicle information of the vehicle 10 does not include a fuel efficiency field.

[0026] Each vehicle 10 traveling within a predetermined area E transmits vehicle information to the management server 100 every time the road link on which the vehicle 10 is traveling changes.

[0027] (Functional configuration) Next, the functional configuration of the management server 100 will be described with reference to Fig. 4. Fig. 4 is a block diagram illustrating an example of the functional configuration of the management server 100 according to this embodiment. In this embodiment, the management server 100 corresponds to an information processing device according to the first aspect of the present disclosure.

[0028] The management server 100 includes a communication unit 110, a control unit 120, and a vehicle information database (vehicle information The management server 100 has as its functional units a link fuel efficiency database (link fuel efficiency DB) 130 and a link fuel efficiency database (link fuel efficiency DB) 140. The communication unit 110 has a function of connecting the management server 100 to the network N1. The communication unit 110 can be realized by the communication I / F 102.

[0029] The control unit 120 has a function of performing arithmetic processing for controlling the management server 100. The control unit 120 can be realized by the processor 101. The control unit 120 performs a process of receiving the vehicle information transmitted from each vehicle 10 using the communication unit 110. Furthermore, the control unit 120 performs a process of storing the vehicle information received from each vehicle 10 in the vehicle information DB 130. The vehicle information DB 130 is constructed in the auxiliary storage unit 104.

[0030] The control unit 120 also includes a calculation unit 121 and a restriction unit 122. The calculation unit 121 calculates the link fuel efficiency for each road link in the predetermined area E1 in a first predetermined period based on the vehicle information of each vehicle 10 stored in the vehicle information DB 130. The link fuel efficiency is the average fuel efficiency of a traveling vehicle on one road link. As described above, the vehicle information of the vehicle 10 using an internal combustion engine as a driving source includes fuel efficiency data. Therefore, when calculating the link fuel efficiency of one road link, the calculation unit 121 extracts the vehicle information of the vehicle 10 that has traveled on the one road link in the first predetermined period from the vehicle information DB 130. The vehicle information includes a road link ID and date and time information. Therefore, based on these pieces of information, the vehicle information of the vehicle 10 that has traveled on the one road link in the first predetermined period can be extracted. Furthermore, the calculation unit 121 extracts the vehicle information including the fuel efficiency data from the extracted vehicle information of the vehicle 10. Then, calculation unit 121 calculates the average value of the fuel efficiency data included in the extracted vehicle information of vehicle 10 as the link fuel efficiency for the first predetermined period of the one road link. By calculating the link fuel efficiency in this manner, even if a BEV or FCEV is traveling on the one road link during the first predetermined period, the number of BEVs and FCEVs is not counted as the number of traveling vehicles when calculating the link fuel efficiency.

[0031] The control unit 120 performs a process of storing the link fuel efficiency for each road link in the first predetermined period calculated by the calculation unit 121 in the link fuel efficiency DB 140. The link fuel efficiency DB 140 is constructed in the auxiliary storage unit 104, similar to the vehicle information DB 130. The link fuel efficiency for each road link stored in the link fuel efficiency DB 140 allows the status of each road link to be understood.

[0032] Therefore, the limiting unit 122 identifies a specific road link based on the link fuel efficiency of each road link stored in the link fuel efficiency DB 140. The specific road link is a road link whose link fuel efficiency in a first predetermined period is smaller than a first threshold value. Such a specific road link can be determined to be a road link in which the fuel efficiency of a traveling vehicle is likely to deteriorate. For example, a road link that is a slope and has more vehicle traffic on the uphill lane than on the downhill lane is considered to be in a situation where the fuel efficiency of a traveling vehicle is likely to deteriorate. In addition, when the uphill lane and the downhill lane on a slope are distinguished as different road links, the road link corresponding to the uphill lane is considered to be highly likely to be in a situation where the fuel efficiency of a traveling vehicle is likely to deteriorate.

[0033] Then, when the specific road link is identified, the restricting unit 122 executes a process for restricting the passage of the internal combustion engine vehicle 10a on the specific road link after a first predetermined period. Specifically, the restricting unit 122 notifies the internal combustion engine vehicle 10a traveling in the specific area E1 that the passage of the internal combustion engine vehicle 10a on the road link identified as the specific road link is prohibited after a first predetermined period. Note that whether or not a certain vehicle 10 traveling in the specific area E1 is an internal combustion engine vehicle can be determined based on information indicating the type of the certain vehicle 10 included in the vehicle information received from the certain vehicle 10. The notification by the restricting unit 122 to the internal combustion engine vehicle 10a traveling in the specific area E1 is executed via the communication unit 110.

[0034] (Information Processing) Next, the flow of information processing executed in the management server 100 according to this embodiment will be described with reference to Fig. 5. Fig. 5 is a flowchart showing the flow of information processing executed by the restriction unit 122 to restrict the passage of the internal combustion engine vehicle 10a on a specific road link. This flow is executed after the first predetermined period has elapsed and in a state in which the link fuel efficiency for each road link is stored in the link fuel efficiency DB 140.

[0035] In this flow, first, in S101, the link fuel efficiency in a first predetermined period is acquired for each road link stored in the link fuel efficiency DB 140. Next, in S102, based on the information acquired in S101, it is determined whether or not a specific road link exists, that is, whether or not a road link exists whose link fuel efficiency is smaller than a first threshold value. Note that the first threshold value is a preset value.

[0036] If a negative determination is made in S102, there is no need to restrict the passage of the internal combustion engine vehicle 10a in the specified area E1 in distinction from other types of vehicles 10. Therefore, in this case, execution of this flow is terminated. On the other hand, if a positive determination is made in S102, processing in S103 is then executed. In S103, a prohibition notice is transmitted to the internal combustion engine vehicle 10a traveling in the specified area E1, notifying that the internal combustion engine vehicle 10a is prohibited from passing on the road link specified as the specific road link. As a result, the passage of the internal combustion engine vehicle 10a on the specific road link is restricted.

[0037] (Action and effect) Among various types of vehicles 10 with different drive sources, the internal combustion engine vehicle 10a has the smallest fuel efficiency under the same conditions. By restricting the passage of the internal combustion engine vehicle 10a on the specific road link, the internal combustion engine vehicle 10a can be encouraged to travel on road links other than the specific road link in the specified area E1.

[0038] According to this, after the first predetermined period, it is possible to suppress deterioration in fuel efficiency of the internal combustion engine vehicle 10a traveling in the predetermined area E1 due to the internal combustion engine vehicle 10a traveling on the specific road link. By suppressing deterioration in fuel efficiency of the internal combustion engine vehicle 10a traveling in the predetermined area E1, it is possible to reduce the total fuel consumption of the entire plurality of vehicles 10 traveling in the predetermined area E1.

[0039] Furthermore, by restricting the passage of the specific road link only to internal combustion engine vehicles 10a after the first predetermined period, the impact on the traffic situation of the vehicles 10 in the specified area E1 can be reduced compared to a case in which the passage of other types of vehicles 10 is also restricted. Therefore, according to the control system 1 of this embodiment, the total fuel consumption of the multiple vehicles 10 traveling in the specified area E1 can be more suitably reduced.

[0040] (Variation 1) A first modified example of this embodiment will be described below. In this modified example as well, if a specific road link exists, the passage of the internal combustion engine vehicle 10a on the specific road link is restricted after a first predetermined period. To this end, the management server 100 transmits a prohibition notification to the internal combustion engine vehicle 10a traveling within the specified area E1, notifying that the internal combustion engine vehicle 10a is prohibited from traveling on the road link identified as the specific road link. However, in this modified example, the management server 100 excludes some of the internal combustion engine vehicles 10a traveling within the specified area E1 from the notification targets.

[0041] More specifically, among the internal combustion engine vehicles 10a traveling in a predetermined area E1, There may be a case where the road links identified as specific road links include vehicles that have a history of traveling the road links identified as specific road links a predetermined number of times or more. Such vehicles can be determined to frequently travel the road links identified as specific road links. Therefore, if such vehicles are prohibited from traveling the road links identified as specific road links, inconvenience may occur.

[0042] Therefore, in this modified example, the management server 100 identifies as permitted vehicles those internal combustion engine vehicles 10a that have a history of traveling a road link identified as a specific road link a predetermined number of times or more during the first specified period. Then, the management server 100 transmits a prohibition notice to vehicles other than the permitted vehicles among the internal combustion engine vehicles 10a traveling within the specified area E1. In other words, a prohibition notice is not transmitted to permitted vehicles. In other words, permitted vehicles are not prohibited from traveling on the road link identified as the specific road link. As a result, permitted vehicles can travel on the specific road link even after the first specified period has passed.

[0043] 6 is a flowchart showing a flow of information processing executed by the restriction unit 122 to restrict the passage of the internal combustion engine vehicle 10a on a specific road link according to this modification. Note that the processing executed in S101 and S102 in this flow is similar to the processing executed in the steps indicated by the same reference numbers in the flow shown in FIG.

[0044] In this flow, if a positive determination is made in S102, the process of S202 is then executed. In S202, permitted vehicles are identified. Here, permitted vehicles are identified based on the vehicle information of each vehicle 10 stored in the vehicle information DB 130. The vehicle information includes a road link ID and date and time information. Therefore, based on this information, it is possible to know how many times the vehicle 10 has traveled along a certain road link during a first predetermined period. Next, in S203, a prohibition notice is transmitted to vehicles other than permitted vehicles among the internal combustion engine vehicles 10a traveling within the predetermined area E1.

[0045] (Variation 2) A second modified example of this embodiment will be described below. In this modified example as well, if a specific road link exists, the passage of the internal combustion engine vehicle 10a on the specific road link is restricted after a first predetermined period of time has elapsed. However, in this modified example, the management server 100 notifies the roadside device, rather than the internal combustion engine vehicle 10a, that the passage of the internal combustion engine vehicle 10a on the road link identified as the specific road link is prohibited.

[0046] 7 is a flowchart showing a flow of information processing executed by the restriction unit 122 to restrict the passage of the internal combustion engine vehicle 10a on a specific road link according to this modification. Note that the processing executed in S101 and S102 in this flow is similar to the processing executed in the steps indicated by the same reference numbers in the flow shown in FIG.

[0047] In this flow, if a positive determination is made in S102, the process of S302 is then executed. In S302, roadside devices installed within a predetermined range including the road link identified as the specific road link are searched for. The roadside devices searched for at this time are devices equipped with digital signage. In this modified example, location information of each roadside device installed in the specified area E1 is stored in advance in the management server 100. Also, each roadside device installed in the specified area E1 is connected to the management server 100 via a network N1.

[0048] Next, in S303, a command to display on a digital signage a message that the internal combustion engine vehicle 10a is prohibited from passing on the road link identified as the specific road link is transmitted to the roadside device found in S302.

[0049] According to this, the passage of combustion engine vehicles on road links specified as specific road links is prohibited. A message that the vehicle is stopped is displayed on a digital sign of a roadside device installed in the vicinity of the road link. As a result, it is possible to restrict the passage of the internal combustion engine vehicle 10a on the specific road link.

[0050] <Second embodiment> The schematic configuration of the control system 1 according to this embodiment is the same as that of the first embodiment. Also, in this embodiment, when a specific road link exists, the passage of the internal combustion engine vehicle 10a on the specific road link is restricted after a first predetermined period. Here, when the passage of the internal combustion engine vehicle 10a on the specific road link is restricted, the internal combustion engine vehicle 10a is prompted to travel on road links other than the specific road link. Therefore, it is considered that the traffic volume on road links other than the specific road link in the specified area E1 increases. As a result, there is a risk that the congestion degree on road links other than the specific road link will increase. Therefore, in this embodiment, the traffic restriction on the internal combustion engine vehicle 10a on the specific road link is released based on the increase rate of the congestion degree on road links other than the specific road link.

[0051] 8 is a block diagram showing an example of a functional configuration of the management server 100 according to the present embodiment. In the present embodiment, the management server 100 has a traffic congestion degree database (traffic congestion degree DB) 150 as a functional unit in addition to the vehicle information DB 130 and the link fuel efficiency DB 140.

[0052] The management server 100 acquires the congestion degree of each road link in the specified area E1. At this time, the management server 100 may receive position information and speed information from each vehicle 10 traveling in the specified area E1. Then, the control unit 120 may calculate the congestion degree of each road link based on the position information and speed information of each vehicle 10. In addition, the management server 100 may receive the congestion degree of each road link from another server device or the like. Then, the congestion degree DB 150 stores the congestion degree of each road link during a first specified period.

[0053] Furthermore, the control unit 120 acquires the congestion degree of each road link when the passage of the internal combustion engine vehicle 10a on the specific road link is restricted after the first predetermined period. Furthermore, the control unit 120 calculates the change rate of the congestion degree of each road link from the first predetermined period after the first predetermined period. At this time, the control unit 120 acquires the congestion degree of each road link during the first predetermined period from the congestion degree DB 150 and calculates the change rate of the congestion degree. Then, when there is a road link in which the increase rate of the congestion degree from the first predetermined period is equal to or greater than a predetermined rate, the control unit 120 releases the restriction on the passage of the internal combustion engine vehicle 10a on the specific road link. Specifically, the control unit 120 transmits a release notification to the internal combustion engine vehicle 10a traveling within the specified area E1 to notify that the prohibition on the internal combustion engine vehicle 10a on the road link identified as the specific road link has been released. Note that the predetermined rate may be a fixed value or may be a value set for each road link.

[0054] When the traffic restriction on the internal combustion engine vehicle 10a on the specific road link is lifted, the internal combustion engine vehicle 10a will be able to travel on the road link that was specified as the specific road link, as in the first specified period. Therefore, it is possible to reduce the degree of congestion on the road link whose congestion degree has increased by a predetermined rate or more since the first specified period.

[0055] 9 is a flowchart showing a flow of information processing executed by the restriction unit 122 to release the traffic restriction of the internal combustion engine vehicle 10a on the specific road link according to this embodiment. This flow is executed by the restriction unit 122 when the traffic of the internal combustion engine vehicle 10a on the specific road link is restricted after a first predetermined period.

[0056] In this flow, in S401, a change rate of the congestion degree of each road link is calculated based on the current congestion degree of each road link and the congestion degree of each road link during a first predetermined period. Next, in S402, it is determined whether or not there is a road link whose congestion degree has increased by a predetermined rate or more since the first predetermined period. If a negative determination is made in S402, the execution of this flow is terminated. In this case, the traffic restriction of the internal combustion engine vehicle 10a on the specific road link is continued.

[0057] On the other hand, if the determination in S402 is affirmative, the process of S403 is then executed. In S403, a lift notification is transmitted to the internal combustion engine vehicle 10a traveling in the predetermined area E1, notifying that the travel ban on the internal combustion engine vehicle 10a on the road link identified as the specific road link has been lifted. As a result, the travel restriction on the internal combustion engine vehicle 10a on the specific road link is lifted.

[0058] (Modification) A modified example of this embodiment will be described below. In the control system 1, there are cases where the passage of the internal combustion engine vehicle 10a is restricted on a plurality of specific road links. In such a case, in this modified example, the restricting unit 122 selects, after the first specified period, a specific road link that has a correlation in terms of vehicle traffic volume with a road link in which the congestion degree has increased by a specified percentage or more since the first specified period. Here, the correlation in terms of traffic volume refers to a correlation between road links such that when the vehicle traffic volume on one road link increases, the vehicle traffic volume on the other road link decreases.

[0059] Then, the restricting unit 122 releases the traffic restriction on the internal combustion engine vehicle 10a on the selected specific road link. Even in this case, it is considered that the traffic volume of vehicles on the road link where the congestion degree has increased by more than a predetermined percentage since the first specified period will decrease. Therefore, it is possible to reduce the congestion degree of the road link where the congestion degree has increased by more than a predetermined percentage since the first specified period. On the other hand, the traffic restriction on the internal combustion engine vehicle 10a is continued for road links other than the selected specific road link among the multiple specific road links. Therefore, it is possible to reduce the total fuel consumption of the multiple vehicles 10 traveling in the specified area E1 as a whole, compared to the case where the traffic restriction on the internal combustion engine vehicle 10a is released on all of the multiple specific road links.

[0060] <Third embodiment> The schematic configuration of the control system 1 according to this embodiment is similar to that of the first embodiment. Hereinafter, the flow of information processing executed in the management server 100 according to this embodiment will be described with reference to FIGS.

[0061] 10 is a flowchart showing a flow of information processing executed by the restricting unit 122 to restrict the passage of the internal combustion engine vehicle 10a on a specific road link according to this embodiment. This flow is executed after the first predetermined period has elapsed and in a state in which the link fuel efficiency for each road link is stored in the link fuel efficiency DB 140. Note that the processes executed in S101, S102, and S103 in this flow are similar to the processes executed in the steps indicated by the same reference numbers in the flow shown in FIG.

[0062] In this flow, when the link fuel efficiency for each road link in the first predetermined period is acquired in S101, the process of S501 is executed next. In S501, the average value Lav of the link fuel efficiency for each road link in the first predetermined period in the predetermined area E1 (hereinafter, sometimes referred to as "average link fuel efficiency Lav") is calculated.

[0063] Next, in S502, it is determined whether the average link fuel efficiency Lav calculated in S501 is smaller than the second threshold value L2. If the determination in S502 is affirmative, the process of S102 is performed next. On the other hand, if a negative determination is made in S502, the execution of this flow is stopped.

[0064] According to this flow, if the average link fuel efficiency Lav in the first specified period in the specified area E1 is equal to or greater than the second threshold, traffic restrictions are not implemented for the internal combustion engine vehicle 10a on the specific road link even if the specific road link exists. If the average link fuel efficiency Lav in the first specified period in the specified area E1 is smaller than the second threshold, traffic restrictions are implemented for the internal combustion engine vehicle 10a on the specific road link if the specific road link exists.

[0065] 11 is a flowchart showing a flow of information processing executed by the restriction unit 122 to release the traffic restriction on the internal combustion engine vehicle 10a on the specific road link according to this embodiment. This flow is executed by the restriction unit 122 when the traffic of the internal combustion engine vehicle 10a on the specific road link is restricted after a first predetermined period.

[0066] In this flow, in S601, the average link fuel efficiency Lav after the first predetermined period in the predetermined area E1 is calculated. Next, in S602, it is determined whether the average link fuel efficiency Lav after the first predetermined period in the predetermined area E1 calculated in S601 is equal to or greater than the third threshold value. If a negative determination is made in S602, the execution of this flow is terminated. In this case, the travel restriction of the internal combustion engine vehicle 10a on the specific road link is continued.

[0067] On the other hand, if the determination in S602 is affirmative, the process of S603 is then executed. In S603, a lift notification is transmitted to the internal combustion engine vehicle 10a traveling in the predetermined area E1, notifying that the travel ban on the internal combustion engine vehicle 10a on the road link identified as the specific road link has been lifted. As a result, the travel restriction on the internal combustion engine vehicle 10a on the specific road link is lifted.

[0068] According to this flow, when a traffic restriction on the internal combustion engine vehicle 10a on a specific road link is implemented and the average link fuel efficiency Lav after a first specified period in a specific area E1 improves to a third threshold value or greater, the traffic restriction on the internal combustion engine vehicle 10a on the specific road link is lifted.

[0069] According to this embodiment, only when the average link fuel efficiency Lav in the predetermined area E1 is small to a certain extent, the traffic restriction of the internal combustion engine vehicle 10a on the specific road link is implemented. Therefore, it is possible to suppress the influence on the traffic situation of the vehicle 10 in the predetermined area E1 caused by the restriction of the traffic of the internal combustion engine vehicle 10a on the specific road link.

[0070] In the second and third embodiments described above, a method similar to that of the second modified example of the first embodiment can be adopted as a method for restricting the passage of the internal combustion engine vehicle 10a on a specific road link. In this case, when the restriction on the passage of the internal combustion engine vehicle 10a on a specific road link is lifted, a command is transmitted to the roadside device to display on a digital signage that the prohibition on the passage of the internal combustion engine vehicle 10a on the road link identified as the specific road link has been lifted.

[0071] <Other embodiments> The above embodiment is merely an example, and the present disclosure may be modified as appropriate without departing from the spirit and scope of the present disclosure. Furthermore, the processes and means described in the present disclosure may be freely combined and implemented as long as no technical contradiction occurs.

[0072] Furthermore, a process described as being performed by one device may be shared and executed by multiple devices. Alternatively, a process described as being performed by different devices may be executed by one device. In a computer system, the hardware configuration (server configuration) by which each function is realized can be flexibly changed.

[0073] The present disclosure can also be realized by supplying a computer program implementing the functions described in the above embodiments to a computer, and having one or more processors of the computer read and execute the program. Such a computer program may be provided to the computer by a non-transitory computer-readable storage medium connectable to the system bus of the computer, or may be provided to the computer via a network. The non-transitory computer-readable storage medium includes any type of medium suitable for storing electronic instructions, such as, for example, a magnetic disk (e.g., a floppy disk, a hard disk drive (HDD), etc.), an optical disk (e.g., a CD-ROM, a DVD disk, a Blu-ray disk, etc.), a read-only memory (ROM), a random access memory (RAM), an EPROM, an EEPROM, a magnetic card, a flash memory, or an optical card.
