[0009] Hereinafter, the information processing device, the information processing method, and the information processing program according to the present application will be described in detail with reference to the drawings. Note that the information processing device, the information processing method, and the information processing program according to the present application are not limited to the embodiments. In addition, the same parts in the following embodiments are given the same reference numerals, and duplicated descriptions are omitted.

[0010] (Embodiment) First, the process executed by the information processing device according to the embodiment will be described with reference to Fig. 1A and Fig. 1B. Fig. 1A is a diagram showing a first process executed by the information processing device according to the embodiment. Fig. 1B is a diagram showing a second process executed by the information processing device according to the embodiment. Fig. 1A and Fig. 1B show an example of the operation of an information processing system S including an information processing device 1 according to the embodiment.

[0011] First, a first process executed by the information processing system S will be described with reference to FIG. 1A.

[0012] 1A, an information processing system S according to an embodiment includes an information processing device 1, a vehicle 50, and a user terminal 100. In addition, hereinafter, the vehicle 50 that is the notification target of the information processing device 1 may be referred to as a target vehicle 50.

[0013] As shown in FIG. 1A, the information processing system S of the embodiment estimates an appropriate speed for a vehicle 50 (target vehicle 50) to pass through a specified area based on people flow information in the specified area, and notifies the target vehicle 50 that is scheduled to pass through the specified area of ​​its passage through the specified area based on the estimated appropriate speed.

[0014] The predetermined area here is an area where people or other moving objects exist, such as facilities such as parks, schools, kindergartens, nursery schools, shopping malls, etc. In other words, the predetermined area is an area where the driver needs to pay attention when the vehicle passes through. Note that the predetermined area is not limited to facilities, and may be specific locations such as crosswalks, intersections, school routes, etc.

[0015] In the process 1 shown in FIG. 1A, the information processing device 1 first acquires driving information of the target vehicle from the target vehicle 50 that is the target of notification (step S1). The driving information acquired includes, for example, the current position, the current speed, the road being driven, the lane being driven, and a guide route to a destination set by a navigation device (step S1). Note that the driving information acquired may be, for example, driving information acquired by a navigation device or a vehicle control device mounted on the target vehicle 50, or driving information acquired by a terminal device such as a smartphone carried by a passenger of the target vehicle 50.

[0016] Next, the information processing device 1 identifies a predetermined area corresponding to the position of the target vehicle 50 based on the acquired travel information of the target vehicle 50 (step S2). For example, the information processing device 1 predicts a planned travel route from the current position of the target vehicle 50, and obtains the predetermined area located on the planned travel route as a identified result. In addition, the information processing device 1 identifies a planned time when the target vehicle 50 will pass through the identified predetermined area.

[0017] Next, the information processing device 1 acquires user location information from the user via the user terminal 100 (step S3). Such users are users who are not in a vehicle (a vehicle other than the target vehicle 50), and are pedestrians, users riding bicycles, etc. In other words, such users are users who may temporarily pass by the road on which the vehicle 50 is traveling.

[0018] Next, the information processing device 1 estimates people flow information in the specified area based on the acquired position information (step S4). The people flow information is information indicating the future flow (location transition) of users in the specified area. For example, the information processing device 1 estimates people flow information for each user at the scheduled time by predicting the transition of location information up to the scheduled time from the history of the acquired location information.

[0019] Next, the information processing device 1 estimates an appropriate speed when the target vehicle 50 passes through a predetermined area based on the estimated pedestrian flow information (step S5). For example, the information processing device 1 estimates the appropriate speed based on feature information extracted from the pedestrian flow information, such as the number of users present in the predetermined area at the scheduled time, the number of users moving in the predetermined area, the number of users passing through a road present in the predetermined area, the number of users walking or riding bicycles in the predetermined area, and attribute information (such as age) of each user present in the predetermined area. Specifically, the information processing device 1 estimates a danger level indicating the possibility that a user will approach the target vehicle 50 when the target vehicle 50 passes through the predetermined area based on the feature information, and estimates the appropriate speed according to the danger level. More specifically, the information processing device 1 determines how much slower the appropriate speed is relative to the legal speed in the predetermined area based on the danger level. That is, the higher the danger level (the higher the risk), the more the information processing device 1 estimates an appropriate speed that is greater in reduction from the legal speed. Note that the estimation of the appropriate speed (or danger level) may use a model generated by machine learning. Specifically, the information processing device 1 performs learning using the above-mentioned feature information extracted from the people flow information as an explanatory variable and the appropriate speed (or danger level) as a target variable to generate and use a model.

[0020] Next, the information processing device 1 compares the current speed of the target vehicle 50 with the estimated appropriate speed (step S6). Specifically, the information processing device 1 acquires a speed difference between the current speed and the appropriate speed as a comparison result. Alternatively, the information processing device 1 may acquire as a comparison result whether the current speed is higher than the appropriate speed.

[0021] Next, the information processing device 1 determines the notification content to be sent to the target vehicle 50 based on the comparison result (step S7). For example, when the current speed is higher than the appropriate speed and the speed difference is equal to or greater than a predetermined value, the information processing device 1 determines the notification content to instruct the target vehicle 50 to slow down to the appropriate speed. When the current speed is higher than the appropriate speed and the speed difference is less than a predetermined value, the information processing device 1 determines the notification content to notify the target vehicle 50 that a user present in a predetermined area is likely to approach the target vehicle 50, or the notification content to notify the position of a user who may pass through the road based on the pedestrian flow information. In other words, when the speed difference is less than a predetermined value, the information processing device 1 determines the notification content to notify information about a user present in a predetermined area.

[0022] In addition, when the current speed is lower than the appropriate speed, the information processing device 1 determines the notification content to inform users in a specified area that there is a high possibility that they will approach the target vehicle 50, and the notification content to inform the users of the positions of users who may be passing through the road based on the people flow information.

[0023] Next, the information processing device 1 notifies the target vehicle 50 scheduled to pass through the predetermined area of ​​the notification regarding the passing of the predetermined area with the determined notification content (step S8). Specifically, the information processing device 1 notifies the target vehicle 50 of the notification content indicating an instruction to slow down the speed to an appropriate speed, the notification content notifying the target vehicle 50 that a user existing in the predetermined area is highly likely to approach the target vehicle 50, and the notification content notifying the position of a user who may pass through the road based on the people flow information.

[0024] In this way, the information processing device 1 according to the embodiment can notify the driver based on the appropriate speed estimated based on the people flow information, allowing the driver to pass through a predetermined area more safely. In other words, the information processing device 1 according to the embodiment can provide the driver with a more appropriate notification in accordance with the surrounding situation (people flow information).

[0025] Note that the information processing device 1 may notify information about the appropriate speed to a system that distributes traffic information, such as VICS (Vehicle Information and Communication System: registered trademark), other than when notifying the target vehicle 50. In addition, the information processing device 1 may notify information about the appropriate speed to an external agency, such as the police. Alternatively, when the target vehicle 50 is an autonomous vehicle, the information processing device 1 may remotely control the target vehicle 50 to keep it at an appropriate speed.

[0026] Next, a second process executed by the information processing system S will be described with reference to Fig. 1B. Note that the second process shown in Fig. 1B may be performed in parallel with the first process shown in Fig. 1A.

[0027] 1B, an information processing system S according to the embodiment includes an information processing device 1, a vehicle 50, and a user terminal 100. In addition, hereinafter, the vehicle 50 that is the notification target of the information processing device 1 may be referred to as a target vehicle 50.

[0028] As shown in FIG. 1B, the information processing system S of the embodiment estimates an appropriate passing method for a target vehicle 50 to pass through a specified area based on the vehicle conditions in the specified area, and notifies a vehicle 50 (target vehicle 50) that is scheduled to pass through the specified area regarding its passage through the specified area based on the estimated passing method.

[0029] In the process 2 shown in FIG. 1B, the information processing device 1 first acquires travel information of the target vehicle 50 from the target vehicle 50 that is the subject of notification (step S1). The travel information acquired includes, for example, the current position, the current speed, the road on which the vehicle is traveling, the lane on which the vehicle is traveling, and a guide route to a destination set by a navigation device (step S1). Note that the travel information acquired may be, for example, travel information acquired by a navigation device or a vehicle control device mounted on the target vehicle 50, or travel information acquired by a terminal device such as a smartphone carried by a passenger of the target vehicle 50.

[0030] Next, the information processing device 1 identifies a predetermined area corresponding to the position of the target vehicle 50 based on the acquired travel information of the target vehicle 50 (step S2). For example, the information processing device 1 predicts a planned travel route from the current position of the target vehicle 50, and obtains the predetermined area located on the planned travel route as a identified result. In addition, the information processing device 1 identifies a planned time when the target vehicle 50 will pass through the identified predetermined area.

[0031] Next, the information processing device 1 acquires location information of a user (another vehicle) from a user who is an occupant of a vehicle other than the target vehicle 50 via the user terminal 100 (step S3). Note that the location information of the other vehicle is not limited to being acquired from the user terminal 100, and may be acquired from a navigation device, a vehicle control device, or the like installed in the other vehicle.

[0032] Next, the information processing device 1 estimates the vehicle status of the other vehicles in the specified area based on the acquired position information of the other vehicles (step S4). The vehicle status is information indicating the future flow (position transition) of the other vehicles in the specified area. For example, the information processing device 1 estimates the vehicle status of each other vehicle at the scheduled time by predicting the transition of the position information up to the scheduled time from the history of the acquired position information.

[0033] Next, the information processing device 1 estimates an appropriate passing method for the target vehicle 50 in the predetermined area based on the estimated vehicle status (step S5). For example, when the predetermined area is an intersection, the information processing device 1 estimates an appropriate passing method based on the position (lane in which the target vehicle 50 is traveling) and speed of the target vehicle 50 and the positions and speeds of other vehicles, depending on whether the target vehicle 50 can go straight through the intersection and whether the target vehicle 50 can turn right or left at the intersection. When the information processing device 1 determines that the target vehicle 50 can go through the intersection and that the target vehicle 50 can turn right at the intersection, the information processing device 1 estimates going straight and turning right as appropriate passing methods. When the information processing device 1 determines that the target vehicle 50 can go through the intersection and that the target vehicle 50 can turn right at the intersection, the information processing device 1 estimates that the appropriate passing methods are going straight and turning right. When the information processing device 1 determines that the target vehicle 50 can change lanes to each lane and that the lane change is possible, the information processing device 1 estimates that the appropriate passing methods are changing lanes and not changing lanes. When the information processing device 1 determines that the target vehicle 50 can enter the predetermined facility and that the target vehicle 50 can enter the facility and passing through the entrance (not entering the facility) as appropriate passing methods.

[0034] Next, the information processing device 1 compares the estimated appropriate passing method with the guide route in the predetermined area set in the target vehicle 50 (step S6). Specifically, the information processing device 1 determines whether the appropriate passing method includes the guide route in the predetermined area. For example, when the guide route at the intersection is a right turn, the information processing device 1 determines whether the appropriate passing method includes a right turn.

[0035] Next, the information processing device 1 determines the notification contents to the target vehicle 50 based on the comparison result (step S7). For example, when the appropriate passing methods include a guide route in a predetermined area, the information processing device 1 determines the notification contents to notify the passing method guided in the guide route. Also, when the appropriate passing methods do not include a guide route in a predetermined area, that is, when it is not appropriate to perform the passing method guided in the guide route, the information processing device 1 determines the notification contents to notify that the passing method guided in the guide route should not be performed. In this case, the information processing device 1 may determine the notification contents to notify a passing method other than the guide route (appropriate passing method). Note that, when there are multiple passing methods other than the guide route, the information processing device 1 may specify a driving level indicating the ease of driving for each passing method, and determine the notification contents to notify the passing method with the highest driving level (highest ease). Alternatively, when there are multiple passing methods other than the guide route, the information processing device 1 may determine the notification contents to notify the passing method with the shortest arrival time to the destination.

[0036] Next, the information processing device 1 notifies the target vehicle 50 scheduled to pass through the predetermined area of ​​the notification regarding the passing of the predetermined area with the determined notification content (step S8). For example, in the case of the notification content notifying the passing method guided by the guide route, the information processing device 1 notifies the passing method guided by the guide route. For example, in the case where the guide route is a right turn, the information processing device 1 notifies the route of turning right in the predetermined area.

[0037] In addition, in the case of notification contents notifying that the passing method guided in the guided route should not be used, the information processing device 1 notifies that the passing method guided in the guided route should not be used. For example, in the case of a guided route being a right turn, the information processing device 1 notifies that it is recommended not to follow the guided route, such as "right turn is not recommended due to the situation of other vehicles". In addition, in the case of notification contents notifying of a passing method (appropriate passing method) other than the guided route, the information processing device 1 notifies of the passing method (appropriate passing method) other than the guided route. For example, in the case of an intersection where the guided route is a right turn and the appropriate passing method is going straight, the information processing device 1 notifies that it is recommended to use an appropriate passing method, such as "right turn is difficult at the upcoming intersection, so going straight is recommended". In addition, in the case of notifying of a passing method with the highest driving level from among a plurality of passing methods, the information processing device 1 notifies of a driving level, such as "right turn is difficult at the upcoming intersection, so going straight is recommended, which is easy to drive". Furthermore, when notifying the driver of the passing method with the shortest arrival time to the destination from among a plurality of passing methods, the information processing device 1 notifies the driver of the arrival time to the destination, such as "Because it is difficult to turn right at the upcoming intersection, we recommend that you go straight, although the arrival time to the destination will be X minutes longer. " When notifying the driver of a passing method other than the guided route, the information processing device 1 may search in advance for a new guided route in case of passing through using a passing method other than the guided route, and notify the driver of the new guided route immediately when the driver passes through using a passing method other than the guided route.

[0038] In this way, the information processing device 1 according to the embodiment notifies the driver of an appropriate passing method estimated based on the vehicle conditions of other vehicles, thereby enabling the driver to pass through a predetermined area more safely. That is, the information processing device 1 according to the embodiment can provide the driver with a more appropriate notification in accordance with the surrounding conditions (vehicle conditions).

[0039] Note that the information processing device 1 may notify a system that distributes traffic information, such as VICS (registered trademark), of information about an appropriate passing method other than when notifying the target vehicle 50. In addition, the information processing device 1 may notify an external agency, such as the police, of information about an appropriate passing method. Alternatively, when the target vehicle 50 is an autonomous vehicle, the information processing device 1 may remotely control the target vehicle 50 to pass by using an appropriate passing method.

[0040] Next, a configuration example of an information processing system S according to an embodiment will be described with reference to Fig. 2. Fig. 2 is a block diagram showing a configuration example of an information processing system S according to an embodiment. As shown in Fig. 2, in the information processing system S according to the embodiment, an information processing device 1, a plurality of vehicles 50, and a plurality of user terminals 100 are connected to a network N by wire or wirelessly. The network N is, for example, a network such as the Internet, a Wide Area Network (WAN), or a Local Area Network (LAN).

[0041] The information processing device 1 is a server device that executes an information processing method according to the embodiment.

[0042] In addition, the information processing device 1 is an information processing device that cooperates with multiple vehicles 50 and multiple user terminals 100 and provides the multiple vehicles 50 and the multiple user terminals 100 with API (Application Programming Interface) services for various applications (hereinafter, apps), etc., as well as various data, and is realized by a server device, a cloud system, etc.

[0043] The information processing device 1 may also be an information processing device that provides some kind of online Web service to a plurality of vehicles 50 and a plurality of user terminals 100. For example, the information processing device 1 may provide services such as Internet connection, search service, SNS (Social Networking Service), electronic commerce (EC), electronic payment, online games, online banking, online trading, hotel and ticket reservations, video and music distribution, news, maps, route search, route guidance, line information, operation information, and weather forecasts as Web services. In practice, the information processing device 1 may cooperate with various servers that provide the above-mentioned Web services and act as an intermediary for the Web services or be responsible for processing the Web services.

[0044] The vehicle 50 is a vehicle traveling on a road, and is configured to be capable of two-way communication with the information processing device 1 via a network N. Note that the connection with the information processing device 1 may be an in-vehicle device provided in the vehicle 50. The in-vehicle device is, for example, a navigation device, a vehicle control device, or the like.

[0045] The user terminal 100 is a terminal device carried by a user. The user terminal 100 may be any type of terminal device, such as a smartphone, a desktop PC, a notebook PC, or a tablet PC. The user terminal 100 transmits various types of information to the information processing device 1 or the like, and receives information provided by the information processing device 1 or the like.

[0046] Next, an example of the configuration of the information processing device 1 will be described with reference to FIG.

[0047] Fig. 3 is a diagram showing an example of the configuration of an information processing device 1 according to an embodiment. As shown in Fig. 3, the information processing device 1 has a communication unit 2, a control unit 3, and a storage unit 4. The control unit 3 includes an acquisition unit 31, an identification unit 32, an estimation unit 33, a comparison unit 34, a determination unit 35, and a notification unit 36. The storage unit 4 stores user information 41 and area information 42.

[0048] The communication unit 2 is realized by, for example, a network interface card (NIC) etc. The communication unit 2 is connected to a network by wire or wirelessly.

[0049] The control unit 3 is a controller, and is realized by, for example, a processor such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) executing various programs (corresponding to an example of an information processing program) stored in a storage device inside the information processing device 1 using a RAM or the like as a working area. The control unit 3 is also a controller, and may be realized by, for example, an integrated circuit such as an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a GPGPU (General Purpose Graphic Processing Unit).

[0050] The storage unit 4 is realized by, for example, a semiconductor memory element such as a random access memory (RAM) or a flash memory, or a storage device such as a hard disk or an optical disk.

[0051] User information 41 is information related to a user. Fig. 4 is a diagram showing an example of user information 41. As shown in Fig. 4, user information 41 includes items such as "user ID", "attribute information", and "location history".

[0052] The "user ID" is identification information for identifying a user. The "attribute information" is information about the attributes of the user, including, for example, psychographic attributes and demographic attributes. The "location history" is information indicating the history of the user's location information.

[0053] The area information 42 is information related to a predetermined area. Fig. 5 is a diagram showing an example of the area information 42. As shown in Fig. 5, the area information 42 includes items such as "area ID" and "facility type".

[0054] The "area ID" is identification information for identifying an area. The "area type" is information indicating the type of a specific area. The "area type" is, for example, the type of facility present in the area, such as a school, kindergarten, nursing home, hospital, etc., or the type of road present in the specific area, such as an intersection, a road with multiple lanes, etc. The type may be the type of person who uses the facility, or the type of service provided by the facility such as a hospital or kindergarten.

[0055] Next, each function (acquisition unit 31, identification unit 32, estimation unit 33, comparison unit 34, determination unit 35, and notification unit 36) of the control unit 3 of the information processing device 1 will be described.

[0056] The acquisition unit 31 acquires various information. For example, the acquisition unit 31 acquires driving information of the target vehicle 50. The acquisition unit 31 also acquires position information of users riding in vehicles other than the target vehicle 50, and position information of users not riding in the target vehicle 50 or other vehicles.

[0057] The identification unit 32 identifies a predetermined area corresponding to the position of the target vehicle 50 based on the acquired travel information of the target vehicle 50. For example, the identification unit 32 predicts a planned travel route from the current position of the target vehicle 50, and obtains a predetermined area located on the planned travel route as an identification result. In addition, the identification unit 32 identifies a planned time when the target vehicle 50 will pass through the identified predetermined area.

[0058] The estimation unit 33 estimates people flow information in the specified area based on the acquired position information. The people flow information is information indicating the future flow (location transition) of users in the specified area. For example, the estimation unit 33 estimates people flow information for each user at the scheduled time by predicting the transition of location information up to the scheduled time from the history of the acquired location information.

[0059] Next, the estimation unit 33 estimates an appropriate speed when the target vehicle 50 passes through a predetermined area based on the estimated pedestrian flow information. For example, the estimation unit 33 estimates the appropriate speed based on characteristic information extracted from the pedestrian flow information, such as the number of users present in the predetermined area at the scheduled time, the number of users moving in the predetermined area, the number of users passing through a road present in the predetermined area, the number of users walking or riding bicycles in the predetermined area, and attribute information (such as age) of each user present in the predetermined area. Specifically, the estimation unit 33 estimates a danger level indicating the possibility that a user will approach the target vehicle 50 when the target vehicle 50 passes through the predetermined area based on the characteristic information, and estimates the appropriate speed according to the danger level. More specifically, the estimation unit 33 determines how much slower the appropriate speed is compared to the legal speed in the predetermined area based on the danger level. That is, the higher the danger level (the higher the risk), the more the estimation unit 33 estimates an appropriate speed that is greater in reduction from the legal speed. Note that the estimation of the appropriate speed (or danger level) may use a model generated by machine learning. Specifically, the information processing device 1 performs learning using the above-mentioned feature information extracted from the people flow information as an explanatory variable and the appropriate speed (or danger level) as a target variable to generate and use a model.

[0060] Furthermore, the estimation unit 33 estimates the vehicle status of the other vehicles in the specified area based on the acquired position information of the other vehicles. The vehicle status is information indicating the future flow (position transition) of the other vehicles in the specified area. For example, the estimation unit 33 estimates the vehicle status of each other vehicle at the scheduled time by predicting the transition of the position information up to the scheduled time from the history of the acquired position information.

[0061] Next, the estimation unit 33 estimates an appropriate passing method for the target vehicle 50 in the predetermined area based on the estimated vehicle status. For example, when the predetermined area is an intersection, the estimation unit 33 estimates an appropriate passing method based on the position (lane in which the target vehicle 50 is traveling) and speed of the target vehicle 50 and the positions and speeds of other vehicles, depending on whether the intersection can be passed straight or whether the intersection can be turned right or left. If the estimation unit 33 determines that the intersection is possible and that the intersection can be turned right, it estimates going straight and turning right as appropriate passing methods. If the predetermined area is a road with multiple lanes, the estimation unit 33 determines whether lane changing to each lane is possible, and if it determines that lane changing is possible, it estimates lane changing and no lane changing as appropriate passing methods. If the predetermined area is an entrance / exit of a predetermined facility, the estimation unit 33 determines whether entry into the predetermined facility is possible, and if it determines that entry is possible, it estimates entry into the predetermined facility and passing through the entrance (not entering) as appropriate passing methods.

[0062] The comparison unit 34 compares the current speed of the target vehicle 50 with the estimated appropriate speed. Specifically, the comparison unit 34 acquires a speed difference between the current speed and the appropriate speed as a comparison result. Alternatively, the information processing device 1 may acquire as a comparison result whether or not the current speed is higher than the appropriate speed.

[0063] Furthermore, the comparison unit 34 compares the estimated appropriate passing method with a guide route in a predetermined area set in the target vehicle 50. Specifically, the comparison unit 34 determines whether or not the appropriate passing methods include the guide route in the predetermined area. For example, when the guide route at an intersection is a right turn, the comparison unit 34 determines whether or not a right turn is included in the appropriate passing methods.

[0064] The determination unit 35 determines the notification content to the target vehicle based on the comparison result. For example, when the current speed is higher than the appropriate speed and the speed difference is equal to or greater than a predetermined value, the determination unit 35 determines the notification content to instruct the target vehicle to slow down to the appropriate speed. In addition, when the current speed is higher than the appropriate speed and the speed difference is less than a predetermined value, the determination unit 35 determines the notification content to inform the target vehicle 50 that a user in a predetermined area is likely to approach the target vehicle 50 or the notification content to inform the target vehicle 50 of the position of a user who may pass through the road based on the pedestrian flow information.

[0065] In addition, when the current speed is lower than the appropriate speed, the determination unit 35 determines the notification content to notify users in a specified area that there is a high possibility that they will approach the target vehicle 50, and the notification content to notify the positions of users who may be passing through the road based on pedestrian flow information.

[0066] Furthermore, when the appropriate passing methods include a guided route in a predetermined area, the determination unit 35 determines the notification content for notifying the user of the passing method guided in the guided route. Furthermore, when the appropriate passing methods do not include a guided route in a predetermined area, that is, when it is not appropriate to use the passing method guided in the guided route, the determination unit 35 determines the notification content for notifying the user that the passing method guided in the guided route should not be used. In this case, the determination unit 35 may determine the notification content for notifying the user of a passing method other than the guided route (an appropriate passing method). Note that, when there are multiple passing methods other than the guided route, the determination unit 35 may specify a driving level indicating the ease of driving for each passing method, and determine the notification content for notifying the user of the passing method with the highest driving level (highest ease). Alternatively, when there are multiple passing methods other than the guided route, the determination unit 35 may determine the notification content for notifying the user of the passing method with the shortest arrival time to the destination.

[0067] The notification unit 36 ​​notifies the target vehicle 50 scheduled to pass through the predetermined area of ​​the notification regarding the passage of the predetermined area with the determined notification content. Specifically, the notification unit 36 ​​notifies the target vehicle 50 of the notification content indicating an instruction to slow down the speed to an appropriate speed, the notification content notifying the target vehicle 50 that a user present in the predetermined area is likely to approach the target vehicle 50, and the notification content notifying the position of a user who may pass through the road based on people flow information.

[0068] In addition, when the notification content is to notify the passing method guided by the guide route, the notification unit 36 ​​notifies the passing method guided by the guide route. For example, when the guide route is a right turn, the notification unit 36 ​​notifies the user of a route that makes a right turn in a predetermined area.

[0069] In addition, in the case of notification contents notifying that the passing method guided in the guided route should not be used, the notification unit 36 ​​notifies that the passing method guided in the guided route should not be used. For example, in the case of a guided route being a right turn, the notification unit 36 ​​issues a notification recommending not following the guided route, such as "right turn is not recommended due to the situation of other vehicles." In addition, in the case of notification contents notifying of a passing method (appropriate passing method) other than the guided route, the notification unit 36 ​​issues a notification recommending a passing method (appropriate passing method) other than the guided route. For example, in the case of an intersection where the guided route is a right turn and the appropriate passing method is going straight, the notification unit 36 ​​issues a notification recommending the appropriate passing method, such as "right turn is difficult at the upcoming intersection, so going straight is recommended." In addition, in the case of notifying of a passing method with the highest driving level from among a plurality of passing methods, the notification unit 36 ​​issues a notification regarding the driving level, such as "right turn is difficult at the upcoming intersection, so going straight is recommended, which is easy to drive." Furthermore, when notifying the driver of the passing method that has the shortest arrival time to the destination from among a plurality of passing methods, the notification unit 36 ​​notifies the driver of the arrival time to the destination, such as "Because it is difficult to turn right at the upcoming intersection, we recommend that you go straight, although the arrival time to the destination will be X minutes longer." Note that, when notifying the driver of a passing method other than the guided route, the notification unit 36 ​​may search in advance for a new guided route in case of passing through using a passing method other than the guided route, and may immediately notify the driver of the new guided route when the driver passes through using a passing method other than the guided route.
