[Overall configuration of wireless communication system]
FIG. 1 is a schematic diagram illustrating an overall configuration of a wireless communication system according to an embodiment. Referring to FIG. 1, a wireless communication system includes a plurality of communication terminals 1A to 1D capable of wireless communication, one or more base stations 2 that wirelessly communicate with communication terminals 1A to 1D, and wired or wirelessly to base station 2. It includes one or more edge servers 3 that communicate with each other and one or more core servers 4 that communicate with the edge servers 3 in a wired or wireless manner. Communication terminals 1A to 1D are also referred to as communication terminals 1 as representative.

The core server 4 is installed in the core data center (DC) of the core network. The edge server 3 is installed in a distributed data center (DC) of a metro network. A metro network is a communication network constructed for each city, for example. Each metro network is connected to a core network. The base station 2 is communicably connected to any edge server 3 of the distributed data center included in the metro network.

The core server 4 is communicably connected to the core network. The edge server 3 is communicably connected to the metro network. Therefore, the core server 4 can communicate with the edge server 3 and the base station 2 belonging to each metro network via the core network and the metro network. The base station 2 includes at least one of a macro cell base station, a micro cell base station, and a pico cell base station.

In the wireless communication system of the present embodiment, the edge server 3 and the core server 4 are general-purpose servers capable of SDN (Software-Defined Networking). The base station 2 and a relay device such as a repeater (not shown) are transport devices capable of SDN. Therefore, a plurality of virtual networks (network slices) S1 to S4 satisfying conflicting service request conditions such as low-latency communication and large-capacity communication can be defined as physical devices of the wireless communication system by network virtualization technology.

The above-mentioned network virtualization technology is a basic concept of “5th generation mobile communication system” (hereinafter abbreviated as “5G”), which is currently being standardized. Therefore, the wireless communication system according to the present embodiment is compliant with 5G, for example.
However, the radio communication system according to the present embodiment may be a mobile communication system capable of defining a plurality of network slices (hereinafter also referred to as “slices”) S1 to S4 according to predetermined service request conditions such as a delay time. What is necessary is just and it is not limited to 5G. Moreover, the hierarchy of slices to be defined is not limited to four, but may be five or more.

In the example of FIG. 1, each network slice S1 to S4 is defined as follows. The slice S1 is a network slice defined so that the communication terminals 1A to 1D communicate directly. The communication terminals 1A to 1D that directly communicate in the slice S1 are also referred to as “node N1”.

The slice S2 is a network slice defined so that the communication terminals 1A to 1D communicate with the base station 2. The highest communication node in the slice S2 (base station 2 in the illustrated example) is also referred to as “node N2”.

The slice S3 is a network slice defined so that the communication terminals 1A to 1D communicate with the edge server 3 via the base station 2. The highest communication node (edge server 3 in the example) in the slice S3 is also referred to as “node N3”. In the slice S3, the node N2 becomes a relay node. That is, data communication is performed through an uplink path of node N1 → node N2 → node N3 and a downlink path of node N3 → node N2 → node N1.

The slice S4 is a network slice defined so that the communication terminals 1A to 1D communicate with the core server 4 via the base station 2 and the edge server 3. The highest communication node in the slice S4 (core server 4 in the figure) is also referred to as “node N4”. In the slice S4, the node N2 and the node N3 are relay nodes. That is, data communication is performed by the uplink path of node N1 → node N2 → node N3 → node N4 and the downlink path of node N4 → node N3 → node N2 → node N1.

In the slice S4, there is a case where the routing does not use the edge server 3 as a relay node. In this case, data communication is performed through the uplink path of node N1 → node N2 → node N4 and the downlink path of node N4 → node N2 → node N1.

When a plurality of base stations 2 (node N2) are included in the slice S2, routing for tracing communication between the

base stations

2 and 2 is also possible. Similarly, when a plurality of edge servers 3 (node N3) are included in the slice S3, routing for tracing communication between the

edge servers

3 and 3 is also possible. When a plurality of core servers 4 (nodes N4) are included in the slice S4, routing that traces communication between the

core servers

4 and 4 is also possible.

The communication terminal 1A is a wireless communication device mounted on the vehicle 5. The vehicles 5 include not only ordinary passenger cars but also public vehicles such as route buses and emergency vehicles. The vehicle 5 may be a two-wheeled vehicle (motorcycle) as well as a four-wheeled vehicle. The drive system of the vehicle 5 may be any of engine drive, electric motor drive, and hybrid system. The driving method of the vehicle 5 may be any of normal driving in which the passenger performs operations such as acceleration / deceleration and steering of the steering wheel, and automatic driving in which the operation is performed by software.

The communication terminal 1 A of the vehicle 5 may be an existing wireless communication device in the vehicle 5, or may be a portable terminal brought into the vehicle 5 by a passenger. The passenger's mobile terminal is temporarily connected to the in-vehicle LAN (Local Area Network) of the vehicle 5 to become an in-vehicle wireless communication device.

The communication terminal 1B is a portable terminal (pedestrian terminal) carried by the pedestrian 7. The pedestrian 7 is a person who moves on foot such as outdoors on roads and parking lots and indoors such as in buildings and underground shopping streets. The pedestrian 7 includes not only a person walking but also a person who rides on a bicycle having no power source.

The communication terminal 1 C is a wireless communication device mounted on the roadside sensor 8. The roadside sensor 8 is an image type vehicle detector installed on the road, a security camera installed outdoors or indoors, and the like. The communication terminal 1D is a wireless communication device mounted on the traffic signal controller 9 at the intersection.

The service request conditions for slices S1 to S4 are as follows. Delay times D1 to D4 allowed for the slices S1 to S4 are defined such that D1 <D2 <D3 <D4. For example, D1 = 1 ms, D2 = 10 ms, D3 = 100 ms, and D4 = 1 s. Data communication amounts C1 to C4 per predetermined period (for example, one day) allowed for the slices S1 to S4 are defined such that C1 <C2 <C3 <C4. For example, C1 = 20 GB, C2 = 100 GB, C3 = 2 TB, C4 = 10 TB.

As described above, in the wireless communication system of FIG. 1, direct wireless communication in the slice S1 (for example, “vehicle-to-vehicle communication” in which the communication terminal 1A of the vehicle 5 directly communicates) and the slice that passes through the base station 2 S2 wireless communication is possible. However, in this embodiment, there is an information providing service for users included in a relatively wide service area (for example, an area including a municipality or a prefecture) using the slice S3 and the slice S4 in the wireless communication system of FIG. is assumed.

The storage unit 34 includes a non-volatile memory element such as a flash memory or an EEPROM (Electrically Erasable Programmable Read Only Memory), or a magnetic storage device such as a hard disk.

The communication unit 35 has a function of communicating with the core server 4 and the base station 2 via the metro network. The communication unit 35 transmits the information given from the control unit 31 to the external device via the metro network and gives the information received via the metro network to the control unit 31.

The storage unit 34 stores a dynamic information map (hereinafter also simply referred to as “map”) M1 as dynamic map information. The map M1 is an aggregate (virtual database) of data in which dynamic information that changes every moment is superimposed on a high-definition digital map that is static information.
The information constituting the map M1 includes the following “dynamic information” and “static information”.

“Dynamic information” refers to dynamic data that requires a delay time of 1 second or less. For example, the position information and signal information of mobile bodies (such as vehicles and pedestrians) that are utilized as ITS (Intelligent Transport Systems) prefetch information correspond to dynamic information.
In addition, the position information of the moving body included in the dynamic information does not have a wireless communication function in addition to the position information of the vehicle 5 and the pedestrian 7 that can perform wireless communication by having the

communication terminals

1A and 1B. Position information of the vehicle 5 and the pedestrian 7 is also included.

“Static information” refers to static data that allows a delay time of one month or less. For example, road surface information, lane information, and three-dimensional structure data correspond to static information.

The control unit 31 of the edge server 3 updates the dynamic information of the map M1 stored in the storage unit 34 every predetermined update cycle (update process). Specifically, the control unit 31 collects, from each communication terminal 1A to 1D, various sensor information acquired by the vehicle 5, the roadside sensor 8, and the like within the service area of its own device at every predetermined update period. The dynamic information of the map M1 is updated based on the collected sensor information.

When receiving the dynamic information request message from the

communication terminal

1A, 1B of the predetermined user, the control unit 31 sends the latest dynamic information to the

communication terminal

1A, 1B that is the transmission source of the request message for each predetermined distribution cycle. Distribute (distribution process).
The control unit 31 collects traffic information and weather information of each location in the service area from the traffic control center and the private weather service support center, and updates the dynamic information or static information of the map M1 based on the collected information. May be.

2, the core server 4 includes a control unit 41 including a CPU, a ROM 42, a RAM 43, a storage unit 44, and a communication unit 45.

The control unit 41 reads one or more programs stored in advance in the ROM 32 into the RAM 43 and executes them to control the operation of each hardware and function as a core server 4 capable of communicating with the edge server 3. Let

The RAM 43 is composed of a volatile memory element such as SRAM or DRAM, and temporarily stores a program executed by the control unit 41 and data necessary for the execution.

The storage unit 44 is configured by a nonvolatile memory element such as a flash memory or an EEPROM, or a magnetic storage device such as a hard disk.

The communication unit 45 has a function of communicating with the edge server 3 and the base station 2 via the core network. The communication unit 45 transmits information given from the control unit 41 to the external device via the core network, and gives information received via the core network to the control unit 41.

As shown in FIG. 2, the storage unit 44 of the core server 4 stores an information map M2. The data structure of the map M2 (data structure including dynamic information and static information) is the same as the data structure of the map M1. The map M2 may be a map of the same service area as the map M1 of the specific edge server 3, or may be a wider area map in which the maps M1 held by the plurality of edge servers 3 are integrated.

Similar to the edge server 3, the control unit 41 of the core server 4 updates the dynamic information of the map M2 stored in the storage unit 44, and the distribution process of distributing the dynamic information in response to the request message. And may be performed. That is, the control unit 41 can perform update processing and distribution processing based on the map M2 of the own device independently of the edge server 3.
That is, the control unit 41 can independently execute dynamic information update processing and distribution processing based on the map M2 of its own device separately from the edge server 3.

However, the core server 4 belonging to the slice S4 has a longer communication delay time with the communication terminals 1A to 1D than the edge server 3 belonging to the slice S3.
For this reason, even if the core server 4 independently updates the dynamic information of the map M2, it is inferior in real time as compared to the dynamic information of the map M1 managed by the edge server 3.
Therefore, for example, it is preferable that the control unit 31 of the edge server 3 and the control unit 41 of the core server 4 perform dynamic information update processing and distribution processing in a distributed manner according to the priority defined for each predetermined area. .

Moreover, if the roadside sensor 8 produces | generates the change point information of own sensor information within the delivery period U1, it will transmit the produced | generated change point information to the edge server 3 (step S6).

When the edge server 3 receives the change point information from the pedestrian terminal 70, the in-vehicle device 50, and the roadside sensor 8 within the update cycle U1, the edge server 3 updates the dynamic information reflecting the change point information (step S7). The updated dynamic information is distributed to the pedestrian terminal 70 and the in-vehicle device 50 (step S8).

For example, when only the in-vehicle device 50 generates change point information within the distribution cycle U1, only the change point information generated by the in-vehicle device 50 in step S4 is transmitted to the edge server 3 (step S6), and the change point The dynamic information that reflects only the information is updated (step S7).
If the pedestrian terminal 70, the in-vehicle device 50, and the roadside sensor 8 do not perform change point information within the distribution cycle U1, the processes of steps S3 to S7 are not executed, and the dynamic information for the previous transmission is transmitted. The same dynamic information as (Step S2) is distributed to the pedestrian terminal 70 and the in-vehicle device 50 (Step S8).
Thus, the edge server 3 updates the dynamic information in step S7 based on the change point information transmitted within the distribution cycle U1.

The pedestrian terminal 70 that has received the dynamic information distributed in step S8 generates change point information within the distribution cycle U2 (step S9), and transmits the generated change point information to the edge server 3 (step S12). ).
The in-vehicle device 50 that has received the dynamic information distributed in step S8 generates change point information from the comparison result between the dynamic information and its own sensor information within the distribution cycle U2 (step S10), and the generated change. The point information is transmitted to the edge server 3 (step S12).
Moreover, if the roadside sensor 8 produces | generates the change point information of own sensor information within the delivery period U2, it will transmit the produced | generated change point information to the edge server 3 (step S12).

When receiving the change point information from the in-vehicle device 50 and the roadside sensor 8 within the distribution cycle U2, the edge server 3 updates the dynamic information reflecting the change point information (step S13), and the updated dynamic information. Is distributed to the pedestrian terminal 70 and the vehicle-mounted device 50 (step S14).
Thus, the edge server 3 updates the dynamic information in step S13 based on the change point information transmitted within the distribution cycle U2.

The processing after step S14 is performed until either the dynamic information distribution stop request message is received from both the pedestrian terminal 70 and the vehicle 5 or the communication between the pedestrian terminal 70 and the vehicle 5 is interrupted. And the same sequence is repeated.

As shown in FIG. 9, the moving body information generated by the detection unit 31d is registered in the moving body database 34a.
The mobile database 34a is managed and updated by the detection unit 31d.
The detection unit 31d refers to the dynamic information map M1, and when the position information of a new moving body (pedestrian 7, vehicle 5) is registered in the dynamic information, the moving body ID is given to the moving body, The mobile body information corresponding to the mobile body ID is generated and registered in the mobile body database 34a. As described above, the detection unit 31d detects a moving body whose position information is registered in the dynamic information map M1, and assigns a moving body ID to each moving body to generate moving body information.

The moving body information includes information such as information on presence / absence of a communication function, vehicle ID (mobile ID), moving body attribute information, position information, direction information indicating a moving direction, and speed information indicating a moving speed. The attribute information is information indicating the type of the moving object, for example, information indicating whether the moving object is a vehicle or a pedestrian.

Thereby, the moving body information registered in the moving body database 34a is maintained in the latest information.

In addition, the evaluation value database 34b in FIG. 8 is a database for registering the evaluation value of the predicted traffic situation obtained by the calculation unit 31a. The evaluation value database 34b will be described later.

[Evaluation value calculation]
FIG. 10 is a flowchart illustrating an example of a calculation process of the evaluation value of the predicted traffic situation by the calculation unit 31a.
As shown in FIG. 10, first, the computing unit 31a reads the mobile object database 34a (step S51), and specifies a mobile object having a communication function as an evaluation target (step S52). Information relating to the predicted traffic situation can be provided to a mobile body having the pedestrian terminal 70 and the in-vehicle device 50. Therefore, the calculating part 31a specifies the mobile body which has the pedestrian terminal 70 and the vehicle-mounted apparatus 50 as an evaluation object which calculates | requires an evaluation value.
That is, the evaluation target refers to a mobile terminal whose evaluation value is obtained by the calculation unit 31a.
In the following description, the evaluation object is a movement having the pedestrian terminal 70 or the in-vehicle device 50 that is the evaluation object in addition to the pedestrian terminal 70 or the in-vehicle device 50 that is carried or mounted on the moving body. It may refer to the body (target moving body).

Next, the calculation unit 31a performs evaluation value calculation processing (step S53).
In the evaluation value calculation process, the calculation unit 31a sequentially executes the process for each of the specified evaluation targets, and repeats the process until it is processed for all the evaluation targets.
In the evaluation value calculation process, the calculation unit 31a first determines whether or not the attribute to be evaluated is a vehicle (step S54).

When it is determined that the attribute to be evaluated is a vehicle (step S54), the calculation unit 31a proceeds to step S55 and performs a calculation process for the vehicle. The calculation unit 31a obtains an evaluation value to be evaluated in the vehicle calculation process (step S55).

FIG. 11 is a flowchart showing an example of the vehicle calculation process in step S55 in FIG.
As illustrated in FIG. 11, the calculation unit 31a identifies a moving body (another moving body) other than the evaluation target (step S61), and a collision between the evaluation target (target moving body) and a moving body other than the evaluation target. The predicted time is calculated for each mobile object other than the evaluation target (step S62).

When the calculation unit 31a refers to the moving object database 34a and the evaluation object and the moving object other than the evaluation object collide with each other from the position information, the azimuth information, and the speed information of the evaluation object and the moving object other than the evaluation object, The estimated collision time is obtained.
When there is no possibility of a collision from the position information and the direction information, the calculation unit 31a sets the collision prediction time to an extremely large predetermined value (for example, 5 minutes). In addition, the calculation unit 31a sets the collision prediction time to the predetermined value even when the calculated collision prediction time is equal to or longer than the predetermined value.

As described above, the calculation unit 31a predicts a collision between the evaluation object and a mobile body other than the evaluation object based on the dynamic information map M1, and obtains a collision prediction time as a prediction result (predicted traffic situation) of the collision prediction. .

The computing unit 31a identifies the mobile body having the shortest predicted collision time among the predicted collision times calculated for each of the mobile bodies other than the evaluation target as a collision prediction target (step S63).
Here, it can be determined that the moving object with the shortest collision prediction time is most likely to collide with the evaluation target. For this reason, the calculating part 31a specifies the mobile body of the shortest collision prediction time as a collision prediction object.

Next, the computing unit 31a obtains an evaluation value of the prediction result (collision prediction result) based on the collision prediction time between the evaluation object and the collision prediction object (step S64).
The calculation unit 31a obtains an evaluation value of the prediction result according to the following rule with respect to the collision prediction time. For example, the setting is as follows, but the present invention is not limited to this.
Collision prediction time is 10 seconds or more: Evaluation value = 0
Collision prediction time is less than 10 seconds: Evaluation value = 20
Collision prediction time is less than 5 seconds: Evaluation value = 100
Collision prediction time is less than 3 seconds: Evaluation value = 200
Collision prediction time is less than 1 second: Evaluation value = 500
The evaluation value is set such that the larger the value, the higher the factor that hinders the safety of the evaluation target. That is, the evaluation value is a value for evaluating the degree of safety of each evaluation object.
The calculation unit 31a sets “0” as the evaluation value for the moving body other than the collision prediction target.

As described above, the calculation unit 31a obtains an evaluation value for each moving object based on the collision prediction time that is a prediction result of the collision prediction between the evaluation object and the moving object other than the evaluation object.
Thereby, the evaluation value of the collision prediction between the evaluation object and the moving object other than the evaluation object can be obtained.

More specifically, the calculation unit 31a selects a mobile body (collision prediction target) that is predicted to collide with the evaluation target among the mobile bodies other than the evaluation target based on the collision prediction time that is a prediction result of the collision prediction. And an evaluation value is obtained based on the collision prediction time for the collision prediction target.
Thereby, it is possible to obtain an evaluation value related to a collision prediction of an evaluation target predicted to collide.

Next, the calculation unit 31a proceeds to step S65, and determines whether or not there is a blind spot factor that causes a blind spot between the evaluation target and the collision prediction target (step S65).
The presence or absence of a blind spot factor between the evaluation target and the collision prediction target is determined by the calculation unit 31a referring to the dynamic information map M1. The computing unit 31a refers to the dynamic information map M1 and determines the presence or absence of a building or other moving body that blocks the prospects of both between the evaluation target and the collision prediction target. When such a building or other moving body exists between the evaluation target and the collision prediction target, the calculation unit 31a determines that there is a blind spot factor between the evaluation target and the collision prediction target. On the other hand, if there is nothing that blocks the line of sight between the evaluation target and the collision prediction target, the calculation unit 31a determines that there is no blind spot factor.

If it is determined in step S65 that there is a blind spot factor between the evaluation target and the collision prediction target, the computing unit 31a adds to the evaluation value obtained in step S64 (step S66), and proceeds to step S67.
On the other hand, when it is determined that there is no blind spot factor between the evaluation target and the collision prediction target (step S65), the calculation unit 31a proceeds to step S67 without performing addition to the evaluation value.

As described above, the evaluation value is set such that the larger the value, the higher the factor that hinders the safety of the evaluation target.
When there is a blind spot factor between the evaluation target and the collision prediction target, the safety is further inhibited in the evaluation target. Therefore, when it determines with there being a blind spot factor, the calculating part 31a adds to an evaluation value.
The added value added to the evaluation value in step S66 is “100”, for example. This added value is an example and is not limited to this. The same applies to the added values shown below.

As described above, the calculation unit 31a determines the presence / absence of a blind spot factor that causes a blind spot between the evaluation target and the collision prediction target, and adds the determination result of the presence / absence of the blind spot factor to the evaluation value.
In this case, the presence / absence of the blind spot factor can be reflected in the evaluation value, and can be reflected in the execution determination of providing information to the evaluation target described later.

Next, in step S67, the calculation unit 31a determines whether or not the collision prediction target is a pedestrian (step S67).
When the collision prediction target (the moving body) is the pedestrian 7, the calculation unit 31a proceeds to step S68, determines the situation of the pedestrian 7 that is the collision prediction target, and finishes the process.

On the other hand, when the collision prediction target (the moving body) is not the pedestrian 7, the collision prediction target is the vehicle 5, and thus the calculation unit 31 a finishes the vehicle calculation process without determining the situation of the pedestrian 7.

FIG. 12 is a flowchart showing an example of the situation determination process for the pedestrian 7 in FIG.
As illustrated in FIG. 12, the calculation unit 31 a determines whether or not the pedestrian 7 subject to collision prediction is walking on a pedestrian crossing or a sidewalk (step S 71).
Whether or not the pedestrian 7 subject to collision prediction is walking on a pedestrian crossing or a sidewalk is determined by referring to the dynamic information map M1 by the calculation unit 31a. The computing unit 31a compares the position information of the pedestrian crossing and the sidewalk included in the static information of the dynamic information map M1 with the position information of the pedestrian 7, so that the pedestrian 7 walks the pedestrian crossing or the sidewalk. It can be determined whether or not.

In step S71, when it determines with the pedestrian 7 of collision prediction object not walking the pedestrian crossing or a sidewalk, the calculating part 31a adds to an evaluation value (step S72), and progresses to step S73.
On the other hand, when it determines with the pedestrian 7 of collision prediction object walking the pedestrian crossing or a sidewalk (step S71), the calculating part 31a progresses to step S73, without performing addition with respect to an evaluation value.

When the pedestrian 7 subject to collision prediction is not walking on a pedestrian crossing or a sidewalk, safety is further inhibited in the evaluation target. Therefore, when it determines with the pedestrian 7 of collision prediction object not walking the pedestrian crossing or a sidewalk, the calculating part 31a adds to an evaluation value.
Note that the added value added to the evaluation value in step S72 is, for example, “100”.

Next, the computing unit 31a determines whether or not the walking speed of the pedestrian 7 to be predicted for collision is slower than a predetermined value (step S73).
Whether or not the walking speed of the pedestrian 7 subject to collision prediction is slower than a predetermined value can be determined by referring to the mobile database 34a.
The predetermined value to be compared with the walking speed is set, for example, every 3.6 km as a general pedestrian speed.

In step S73, when it determines with the walking speed of the pedestrian 7 of collision prediction object being slower than predetermined value, the calculating part 31a adds to an evaluation value (step S74), and progresses to step S75.
On the other hand, when it determines with the walking speed of the pedestrian 7 of collision prediction object not being slower than predetermined value (step S73), the calculating part 31a progresses to step S75, without adding with respect to an evaluation value.

For example, when the pedestrian 7 subject to collision prediction is crossing a pedestrian crossing and the walking speed of the pedestrian 7 is slower than a predetermined value, the pedestrian 7 may not cross the pedestrian crossing during the green light. Considering the fact that there is, there is a safety hindrance factor in the evaluation target. Therefore, when it determines with the walking speed of the pedestrian 7 being slower than a predetermined value, the calculating part 31a adds to an evaluation value.
Note that the added value added to the evaluation value in step S74 is, for example, “100”.

Next, the computing unit 31a determines whether or not the attribute of the pedestrian 7 to be predicted for collision is a child (step S75).
Whether or not the attribute of the pedestrian 7 to be predicted for collision is a child can be determined by referring to the mobile database 34a.

In step S75, when it determines with the attribute of the pedestrian 7 of collision prediction object being a child, the calculating part 31a adds to an evaluation value (step S76), and progresses to step S77.
On the other hand, when it determines with the attribute of the pedestrian 7 of collision prediction object not being a child (step S75), the calculating part 31a progresses to step S77, without performing addition with respect to an evaluation value.

When the pedestrian 7 subject to collision prediction is a child, it becomes an obstacle to safety in the evaluation target. Therefore, when the attribute of the pedestrian 7 subject to collision prediction is determined to be a child, the calculation unit 31a adds to the evaluation value.
The added value added to the evaluation value in step S76 is “100”, for example.

Next, the calculation unit 31a determines whether or not the pedestrian 7 subject to collision prediction is meandering (step S77).
Whether or not the pedestrian 7 subject to collision prediction is meandering can be determined based on a time-dependent change in the position information of the moving body included in the moving body database 34a or the dynamic information map M1.

In step S77, when it is determined that the pedestrian 7 subject to collision prediction is meandering, the calculation unit 31a adds the evaluation value (step S78), and proceeds to step S79.
On the other hand, when it determines with the pedestrian 7 of collision prediction object not meandering (step S77), the calculating part 31a progresses to step S79, without performing addition with respect to an evaluation value.

When the pedestrian 7 subject to collision prediction is meandering, it becomes an obstacle to safety in the evaluation target. Therefore, when it determines with the pedestrian 7 of a collision prediction object meandering, the calculating part 31a adds to an evaluation value.
The added value added to the evaluation value in step S78 is, for example, “100”.

Next, the calculation unit 31a determines whether or not the pedestrian 7 to be predicted for collision is ignoring the signal (step S79).
Whether or not the pedestrian 7 subject to collision prediction ignores the signal can be determined based on the signal information included in the dynamic information of the dynamic information map M1 and the position information of the moving body.

In step S79, when it is determined that the pedestrian 7 subject to collision prediction ignores the signal, the calculation unit 31a adds to the evaluation value (step S80), and ends the vehicle calculation process (FIG. 11).
On the other hand, when it determines with the pedestrian 7 of collision prediction object not ignoring a signal (step S79), the calculating part 31a complete | finishes the calculation process for vehicles (FIG. 11), without adding with respect to an evaluation value.

When the pedestrian 7 subject to collision prediction ignores the signal, it becomes an obstacle to safety in the evaluation target. Therefore, when it determines with the pedestrian 7 of collision prediction object ignoring a signal, the calculating part 31a adds to an evaluation value.
Note that the addition value added to the evaluation value in step S79 is, for example, “100”.

Thus, in the situation determination process, the calculation unit 31a acquires the situation regarding the pedestrian 7, and adds the added value as the adjustment value according to the acquired situation of the pedestrian 7 to the evaluation value.

As described above, the calculation unit 31a performs the vehicle calculation process (step S55 in FIG. 10) to obtain the evaluation value to be evaluated.

On the other hand, when it is determined in step S54 in FIG. 10 that the attribute to be evaluated is not a vehicle (step S54), the calculation unit 31a proceeds to step S56 and performs a pedestrian calculation process. The computing unit 31a obtains an evaluation value to be evaluated in the pedestrian computation process (step S56).

FIG. 13 is a flowchart showing an example of the pedestrian calculation process in FIG.
In FIG. 13, Step 61 to Step S 66 are the same processes as those in FIG. 11 except for whether the evaluation target is a vehicle or a pedestrian. Therefore, description of step 61 to step S66 is omitted.

In FIG. 13, when the process of step S65 or step S66 is completed, the arithmetic unit 31a proceeds to step S82.
In step 82, the calculation unit 31a determines whether or not the collision prediction target is a vehicle (step S82).
When it determines with a collision prediction object (its mobile body) being a vehicle, the calculating part 31a progresses to step S83, performs the situation determination of the pedestrian 7 which is an evaluation object, and complete | finishes the calculation process for pedestrians.
Here, the situation determination process of the pedestrian 7 to be evaluated is the same as in FIG.

On the other hand, when it is determined that the collision prediction target (the moving body) is not a vehicle, the calculation unit 31a finishes the pedestrian calculation process without determining the situation of the evaluation target pedestrian 7.
In the calculation process for pedestrians, the rule regarding the evaluation value according to the collision prediction time and the addition value added to the evaluation value by each determination are the calculation process for the vehicle in consideration of being a pedestrian. Set to a different value.

Note that the calculation unit 31a determines whether or not the collision prediction target is a pedestrian in step S67 in FIG. 11 showing the vehicle calculation process, and only when the collision prediction target (the moving body) is the pedestrian 7. Then, the situation of the pedestrian 7 that is a collision prediction target is determined.
Similarly, in step S82 in FIG. 13 showing the pedestrian calculation process, the calculation unit 31a determines whether or not the collision prediction target is a vehicle, and determines that the collision prediction target (the moving body) is a vehicle. Only when it does, the situation determination of the pedestrian 7 which is an evaluation object is performed.

As described above, when either one of the evaluation object and the moving body predicted to collide with the evaluation object is a pedestrian, the calculation unit 31a acquires the situation related to the pedestrian and acquires the acquired pedestrian. 7 is added to the evaluation value.
In this case, the situation unique to the pedestrian can be reflected in the evaluation value, and can be reflected in the execution determination for providing information to the evaluation target described later.

Returning to FIG. 10, when the evaluation value of the evaluation target is obtained by the vehicle calculation process of step S55 or the pedestrian calculation process of step S56, the calculation unit 31a proceeds to step S57 and uses the calculated evaluation value as the evaluation value. Registration in the database 34b (step S57).

The calculation unit 31a sequentially performs the processing from step S54 to step S57 in FIG. 10 on the specified evaluation target, and repeats the processing until all the evaluation targets are processed.
When the calculation unit 31a obtains evaluation values for all the specified evaluation targets and registers them in the database 34b, the calculation unit 31a returns to step S51 again and repeats the same processing.

Therefore, the calculation unit 31a repeatedly calculates and registers the evaluation value of each specified evaluation target by repeating the calculation process, and updates the registration content of the evaluation value database 34b as needed.

FIG. 14 is a diagram illustrating an example of the evaluation value database 34b.
As shown in FIG. 14, in the evaluation value database 34b, the mobile object ID to be evaluated and the evaluation values of mobile objects other than the evaluation object are registered in association with each other.

The evaluation value database 34b is provided with a mobile object ID field to be evaluated, a vehicle ID (mobile ID) field, and a mobile object evaluation value field other than the evaluation object.
The mobile object ID of the mobile object specified as the evaluation object is registered in the column of the evaluation object mobile object ID.
In the column of vehicle ID (mobile ID), the vehicle ID (mobile ID) of the mobile terminal pedestrian terminal 70 or the in-vehicle device 50 included in the mobile object to be evaluated is registered.

The column of the evaluation value of the mobile body other than the evaluation target includes a mobile body ID column of each mobile body other than the evaluation target. Thereby, the evaluation value of each of the plurality of mobile objects is registered in the column of the evaluation value of the mobile object other than the evaluation object.
As described above, the evaluation value for the moving object other than the collision prediction target is set to “0”.
Therefore, a mobile body other than the evaluation target in which a value other than “0” is registered as the evaluation value of the mobile body other than the evaluation target indicates that the evaluation target is a collision prediction target.

For example, in FIG. 14, in the evaluation value of the evaluation target with the mobile object ID “1006”, the column corresponding to “1004” in the mobile object ID among the evaluation value fields of the mobile objects other than the evaluation object is evaluated. “500” is registered as a value, and “0” is registered in other cases. From this, it can be seen that the moving object with the moving object ID “1004” is specified as the evaluation target collision prediction target with the moving object ID “1006”.
Thus, the collision prediction object of each evaluation object can be specified by referring to the evaluation value database 34b.

[Evaluation value judgment process]
FIG. 15 is a flowchart illustrating an example of a determination process performed by the determination unit 31b.
As illustrated in FIG. 15, the determination unit 31b refers to the evaluation value database 34b and determines whether there is an evaluation target whose evaluation value is equal to or greater than a preset threshold value (step S85).
If it determines with there being no evaluation object whose evaluation value is more than a threshold value in step S85, the determination part 31b will repeat step S85 further. Therefore, the determination unit 31b repeats Step S85 until it is determined that there is an evaluation target whose evaluation value is equal to or greater than the threshold value.

If it is determined in step S85 that there is an evaluation object whose evaluation value is equal to or greater than the threshold value, the determination unit 31b proceeds to step S86 and determines to notify the evaluation object of information related to the collision prediction result of the collision prediction object. Return to step S85.

The determination unit 31b refers to the evaluation value of each evaluation object, and if there are a plurality of evaluation objects whose evaluation values are equal to or greater than the threshold value, determines the notification of information related to the collision prediction result of the collision prediction object to all the evaluation objects. .
As described above, the determination unit 31b determines, for each evaluation target, whether or not to notify the evaluation target of information related to the prediction result of each evaluation target based on the evaluation value.

That is, in this embodiment, whether or not to notify information related to the collision prediction result (information related to the predicted traffic situation) is determined for each of the evaluation targets (the pedestrian terminal 70, the in-vehicle device 50, or the mobile body having these). Since it determines for every evaluation object based on the evaluation value of a prediction result, required information can be appropriately provided to each evaluation object.
In addition, since the dynamic information map M1 on which dynamic information on a plurality of moving objects is superimposed is used in order to obtain the evaluation value of the prediction result of the collision prediction of each evaluation target, there is also a moving object on which no mobile terminal is mounted. In addition, the evaluation value of the predicted traffic situation can be obtained, and the traffic situation appropriately predicted for each evaluation target can be expressed as the evaluation value.
Thus, according to the said structure, the information regarding the prediction result appropriately collided can be appropriately provided to each evaluation object.

[Notification processing]
When the determination unit 31b determines to notify the evaluation target of information related to the collision prediction result, the notification unit 31c determines the collision prediction result between the evaluation target and the collision prediction target to the evaluation target for which the determination unit 31b has determined the notification. Notify information about.
Thereby, it is possible to provide information only to the mobile terminal that is determined to need information on the prediction result of the collision prediction based on the evaluation value.
The information related to the collision prediction result notified to the evaluation target by the notification unit 31c includes the attribute of the collision prediction target, the direction in which the collision prediction target approaches, the collision prediction time, and the like.

The mobile terminal (the pedestrian terminal 70 and the in-vehicle device 50) to be evaluated that has received the notification by the notification unit 31c outputs information on the notified prediction result to the user of the mobile terminal.

[About scenario 1]
Next, the operation of the information providing system of the present embodiment will be described according to a scenario assumed on the road.
FIG. 16 is a diagram illustrating a situation around an intersection according to scenario 1. FIG.
In FIG. 16, pedestrians 7 A and 7 B get off the vehicle 5 C parked at a position immediately after passing the pedestrian crossing P and cross the pedestrian crossing P. The pedestrian 7A is an adult, and the pedestrian 7B is a child.
At the timing when the

pedestrians

7A and 7B started to cross the pedestrian crossing P, the light color of the signal of the pedestrian crossing P was flashing blue.

On the other hand, at the timing when the

pedestrians

7A and 7B start crossing the pedestrian crossing P, the light color of the signal of the route on which the vehicle 5A travels is red, but the signal of the pedestrian crossing P is blinking blue. The vehicle 5A approaching the pedestrian crossing P recognizes that it will soon turn blue. For this reason, it is assumed that the vehicle 5A attempts to pass through the intersection without stopping.
It is assumed that the

pedestrians

7A and 7B cannot see the vehicle 5A due to the presence of the vehicle 5C.
Further, a vehicle 5B further travels behind the vehicle 5A.

The

vehicles

5A, 5B, 5C and

pedestrians

7A, 7B are registered as moving bodies in the dynamic information map M1 and the moving body database 34a by the system.
Further, it is assumed that the

vehicles

5A and 5B are equipped with the in-vehicle device 50, and the

pedestrians

7A and 7B carry the pedestrian terminal 70.

Here, it is assumed that in the middle of the pedestrian crossing P, the signal color of the pedestrian crossing P changes to red, and the

pedestrians

7A and 7B hurry to cross the pedestrian crossing P as they are.

At this time, the vehicle 5A and the

pedestrians

7A and 7B may collide at the pedestrian crossing P. Therefore, the edge server 3 (the computing unit 31a thereof) specifies the

pedestrians

7A and 7B as the collision prediction targets of the vehicle 5A and specifies the vehicle 5A as the collision prediction targets of the

pedestrians

7A and 7B. The

pedestrians

7A and 7B have a child attribute (only the pedestrian 7B) and ignore the signal. Furthermore, a vehicle 5C that is a blind spot factor exists between the vehicle 5A and the

pedestrians

7A and 7B.

In such a case, when the edge server 3 obtains an evaluation value when the vehicle 5A is an evaluation object, the pedestrian situation determination is taken into consideration in addition to the collision prediction time. In this scenario, an additional value is added to the evaluation value due to blind spot factor, pedestrian attributes, and signal ignorance.
The threshold value used for determining whether or not to notify the prediction result is set smaller than the evaluation value in the case where factors that inhibit safety overlap as in this scenario. Therefore, in the case of this scenario, the evaluation values of the

pedestrians

7A and 7B in the vehicle 5A are larger than the threshold value. For this reason, the edge server 3 notifies the information regarding the collision prediction result of the

pedestrians

7A and 7B in the vehicle 5A to the vehicle 5A.

Moreover, the edge server 3 also considers the pedestrian's situation determination in addition to the collision prediction time when obtaining the evaluation value when the

pedestrians

7A and 7B are evaluated. Therefore, the evaluation value of the vehicle 5A in the

pedestrians

7A and 7B becomes a value larger than the threshold value, and the edge server 3 notifies the

pedestrians

7A and 7B of the information related to the collision prediction result of the vehicle 5A in the

pedestrians

7A and 7B. .

Furthermore, also in the vehicle 5B, the speed decreases as the vehicle 5A approaches the pedestrian crossing P, and when both vehicles approach, the edge server 3 specifies the vehicle 5A as a collision prediction target of the vehicle 5B. As a result of the collision prediction, if the collision prediction time is short, the evaluation value is set to a large value. As a result, the edge server 3 notifies the vehicle 5B of information related to the collision prediction result of the vehicle 5A in the vehicle 5B.

As described above, the edge server 3 can appropriately provide necessary information to each mobile terminal.
The in-vehicle device 50 of the

vehicles

5A and 5B and the pedestrian terminal 70 of the

pedestrians

7A and 7B output information on the collision prediction result to the user of the own device based on the notification from the edge server 3.

In FIG. 16, on the output screen V1 of the in-vehicle device 50 of the vehicle 5A, a display D1 indicating that a pedestrian appears from the right side of the pedestrian crossing P in front of the host vehicle, an arrow D2 indicating the traveling direction of the pedestrian, and the like. Is displayed.
Thereby, the edge server 3 can make the user of the vehicle 5A recognize in advance that a pedestrian appears from the right side of the pedestrian crossing P ahead.
Here, the

pedestrians

7A and 7B are displayed without specifying them. However, for example, the display method may be different depending on whether the attribute of the pedestrian 7 is a child or an adult. . This is because pedestrians need more attention if they are children.

That is, in this system, the output mode of the information related to the collision prediction result may be controlled differently according to the attribute of the collision prediction target. Thereby, information can be output to a user in the output mode according to the feature of the attribute of a collision prediction object.

The output screen V2 of the pedestrian terminals 70 of the

pedestrians

7A and 7B includes a display D3 indicating that the vehicle A appears from the left side of the front pedestrian crossing P, an arrow D4 indicating the traveling direction of the vehicle 5A, and the like. Is displayed.
Thereby, the edge server 3 can make the

pedestrians

7A and 7B recognize in advance that the vehicle appears from the left side of the pedestrian crossing P ahead.

In addition, on the output screen V3 of the in-vehicle device 50 of the vehicle 5B, a display D5 or the like indicating a warning to the vehicle 5A traveling in front of the host vehicle is displayed.
Thereby, the edge server 3 can make the user of the vehicle 5B recognize in advance that the vehicle 5A traveling ahead stops and approaches.

In this way, the edge server 3 can avoid collision between the moving bodies by causing the in-vehicle device 50 of the

vehicles

5A and 5B and the pedestrian terminal 70 of the

pedestrians

7A and 7B to output to the user. it can.

In addition, the output of the information regarding the collision prediction result by the pedestrian terminal 70 and the vehicle-mounted apparatus 50 is controlled by the output control part which the control part 71 and the control part 51 of the pedestrian terminal 70 and the vehicle-mounted apparatus 50 have.
Moreover, when the control part 31 of the edge server 3 has an output control part which can control the output toward the user by the pedestrian terminal 70 and the vehicle-mounted apparatus 50, the output control part of the edge server 3 is You may control the output to the user by the pedestrian terminal 70 and the vehicle-mounted apparatus 50. FIG.

[About scenario 2]
FIG. 17 is a diagram illustrating a situation around an intersection according to scenario 2.
In FIG. 17, the settings of the

vehicles

5A and 5B and the

pedestrians

7A and 7B are the same as in the scenario 1. In scenario 2, there is no scenario 5 vehicle 5C.
In scenario 2, the

pedestrians

7A and 7B cross the pedestrian crossing P at a speed lower than a general walking speed (3.6 km / hour).

Since the

pedestrians

7A and 7B slowly cross the pedestrian crossing P, the signal color of the pedestrian crossing P was flashing blue at the timing when the

pedestrians

7A and 7B started to cross the pedestrian crossing P. In the middle of the pedestrian crossing P, the signal color of the pedestrian crossing P turns red, and the

pedestrians

7A and 7B slowly cross the pedestrian crossing P at the same walking speed.

In this case, as in scenario 1, there is no blind spot factor between the vehicle 5A and the

pedestrians

7A and 7B.
Moreover, since the

pedestrians

7A and 7B slowly cross the pedestrian crossing P, the light color of the signal of the pedestrian crossing P, which was flashing in blue, turns red in the middle of the pedestrian crossing P, and the

pedestrians

7A and 7B Is slowly crossing the pedestrian crossing P at the same walking speed.
Here, the vehicle 5A and the

pedestrians

7A and 7B may collide on the pedestrian crossing. Therefore, the edge server 3 specifies the

pedestrians

7A and 7B as the collision prediction targets of the vehicle 5A, and specifies the vehicle 5A as the collision prediction targets of the

pedestrians

7A and 7B.

At this time, when the edge server 3 obtains an evaluation value when the vehicle 5A is an evaluation object, the pedestrian attribute, the speed of the pedestrian, and an addition value obtained by ignoring the signal are added to the evaluation value obtained from the collision prediction time. to add.
Thereby, the evaluation value of the

pedestrians

7A and 7B in the vehicle 5A becomes a value larger than the threshold value, and the edge server 3 notifies the vehicle 5A of information regarding the collision prediction result of the

pedestrians

7A and 7B in the vehicle 5A.

In addition, the edge server 3 also considers the pedestrian's situation determination in addition to the collision prediction when obtaining the evaluation value when the

pedestrians

7A and 7B becomes a value larger than the threshold value, and the edge server 3 sends the information regarding the prediction result of the collision prediction of the vehicle 5A in the

pedestrians

7A and 7B to the

pedestrians

7A and 7B. Notice.

As described above, the in-vehicle device 50 of the

vehicles

5A and 5B and the pedestrian terminal 70 of the

pedestrians

7A and 7B output information on the collision prediction result to the user of the own device based on the notification from the edge server 3.
Thereby, the edge server 3 can make the user of the vehicle 5A recognize in advance that a pedestrian appears from the right side of the pedestrian crossing P ahead.
Further, the edge server 3 can make the

pedestrians

7A and 7B recognize in advance that a vehicle appears from the left side of the front crosswalk P.

Thereby, the edge server 3 can avoid the collision of each moving body by making the vehicle-mounted apparatus 50 of

vehicle

5A, 5B and the pedestrian terminal 70 of

pedestrian

7A, 7B perform an output to a user. .

[About scenario 3]
FIG. 18 is a diagram illustrating a situation around an intersection according to scenario 3.
In FIG. 18,

pedestrians

7A and 7B walk along the sidewalk H, and there is an obstacle G1 on the sidewalk H. The

pedestrians

7A and 7B are walking on the roadway avoiding the obstacle G1. The pedestrian 7A is an adult, and the pedestrian 7B is a child.

Here, there is a possibility of collision between the vehicle 5A and the

pedestrians

7A and 7B on the roadway. Therefore, the edge server 3 specifies the

pedestrians

7A and 7B. In addition, the attributes of the

pedestrians

7A and 7B are children (only the pedestrian 7B) and do not walk on the sidewalk.

At this time, when the edge server 3 obtains the evaluation value of the

pedestrians

7A and 7B when the vehicle 5A is the evaluation target, the attribute of the pedestrian and the pedestrian walk to the evaluation value obtained from the predicted collision time. Add the value depending on where you are (whether you are walking on a pedestrian crossing or sidewalk).
Thereby, the evaluation value of the

pedestrians

7A and 7B in the vehicle 5A.

pedestrians

7A and 7B. .

Also, if the vehicle 5A tries to protrude to the opposite lane side while avoiding the

pedestrians

7A and 7B, the vehicle 5B traveling in the opposite lane may collide with the vehicle 5A. Therefore, in this case, the edge server 3 specifies the vehicle 5A as a collision prediction target of the vehicle 5B. Further, a vehicle 5D that is a blind spot factor exists between the vehicle 5B and the vehicle 5A.

When the edge server 3 obtains an evaluation value when the vehicle 5B is an evaluation object, the edge server 3 adds an addition value based on the presence or absence of a blind spot factor to the evaluation value obtained from the collision prediction time.
If the evaluation value of the vehicle 5A in the vehicle 5B is larger than the threshold value, the edge server 3 notifies the vehicle 5B of information related to the collision prediction result of the vehicle 5A in the vehicle 5B.

Also, in the vehicle 5C, when the vehicle 5B reduces the speed due to the protrusion of the vehicle 5A and both vehicles approach, the edge server 3 specifies the vehicle 5B as a collision prediction target of the vehicle C. As a result of the collision prediction, if the collision prediction time is short, the evaluation value is set to a large value. As a result, the edge server 3 notifies the vehicle 5C of information related to the collision prediction result of the vehicle 5B in the vehicle 5C.

Thereby, the edge server 3 makes the in-vehicle device 50 of the

vehicles

5A, 5B, and 5C and the pedestrian terminal 70 of the

pedestrians

7A and 7B perform the output to the user, thereby avoiding collision between the moving bodies. Can do.

[About scenario 4]
FIG. 19 is a diagram illustrating a situation around an intersection according to scenario 4.
In FIG. 19, as

pedestrians

7A and 7B walk along the sidewalk H, they are walking between the parked vehicle 5C and the vehicle 5D and are not crosswalks to cross the roadway. The pedestrian 7A is an adult, and the pedestrian 7B is a child.

Here, there is a possibility of collision between the vehicle 5A traveling in the opposite lane and the

pedestrians

7A and 7B on the roadway. Therefore, the edge server 3 specifies the

pedestrians

7A and 7B. The attributes of the

pedestrians

7A and 7B are children (only the pedestrian 7B) and do not walk on the sidewalks and pedestrian crossings. Further, a vehicle 5D that is a blind spot factor exists between the vehicle 5A and the

pedestrians

7A and 7B.

At this time, when the edge server 3 calculates the evaluation value of the

pedestrians

7A and 7B when the vehicle 5A is the evaluation target, in addition to the collision prediction time, the attribute of the pedestrian, the place where the pedestrian is walking (crossing) The added value is added to the evaluation value depending on whether there is a sidewalk or whether or not walking on the sidewalk and whether there is a blind spot factor.
Thereby, the evaluation value of the

pedestrians

7A and 7B in the vehicle 5A.

pedestrians

7A and 7B. .

Also in the vehicle 5B, when the vehicle 5A drops its speed due to the crossing of the roadway of the

pedestrians

7A and 7B and both vehicles approach, the edge server 3 specifies the vehicle 5A as a collision prediction target of the vehicle 5B. As a result of the collision prediction, if the collision prediction time is short, the evaluation value is set to a large value. As a result, the edge server 3 notifies the vehicle 5B of information related to the collision prediction result of the vehicle 5A in the vehicle 5B.

In addition, as a method of detecting a moving body (pedestrian) that slips between the vehicles 5 as in this scenario, in-vehicle device that includes the in-vehicle camera 59 in the vehicle 5 through which the pedestrian slips, in addition to detection by the roadside sensor 8. If 50 is mounted, the vehicle-mounted camera 59 can also detect it.

[About scenario 5]
FIG. 20 is a diagram illustrating a situation around an intersection according to scenario 5. In FIG.
In FIG. 20,

pedestrians

7A and 7B meander along the sidewalk H and walk. The pedestrian 7A is an adult, and the pedestrian 7B is a child.

If the

pedestrians

7A and 7B meander along the sidewalk H and protrude from the roadway, the vehicle 5A and the

pedestrians

7A and 7B may collide on the roadway. Therefore, the edge server 3 specifies the

pedestrians

7A and 7B. In addition, the attributes of the

pedestrians

7A and 7B are children (only the pedestrian 7B), and when the pedestrians protrude from the roadway, they are not walking on the sidewalk.

At this time, when the edge server 3 obtains the evaluation value of the

pedestrians

7A and 7B when the vehicle 5A is the evaluation target, the evaluation value obtained from the collision prediction time includes the attribute of the pedestrian, the walking state of the pedestrian ( Addition value depending on whether or not meandering and a place where a pedestrian is walking (whether or not walking on a pedestrian crossing or a sidewalk).
Thereby, the evaluation value of the

pedestrians

7A and 7B in the vehicle 5A.

pedestrians

7A and 7B. .

pedestrians

7A and 7B, the vehicle 5B traveling in the opposite lane may collide with the vehicle 5A. Therefore, in this case, the edge server 3 specifies the vehicle 5A as a collision prediction target of the vehicle 5B.

The edge server 3 calculates | requires the evaluation value when the vehicle 5B is made into evaluation object based on the collision prediction time between

pedestrians

7A and 7B.
If the evaluation value of the vehicle 5A in the vehicle 5B is larger than the threshold value, the edge server 3 notifies the vehicle 5B of information related to the collision prediction result of the vehicle 5A in the vehicle 5B.

[About scenario 6]
FIG. 21 is a diagram illustrating a situation around an intersection according to scenario 6. In FIG.
In FIG. 21,

pedestrians

7A and 7B cross a pedestrian crossing P that crosses a route R1. At the timing when the

pedestrians

7A and 7B start to cross the pedestrian crossing P, the signal color of the pedestrian crossing P was flashing blue. The color changes to red, and the

pedestrians

7A and 7B hurry to cross the pedestrian crossing P as they are. The pedestrian 7A is an adult, and the pedestrian 7B is a child.

The vehicle 5A enters the intersection from the route R2, turns left, and travels in the intersection toward the route R1. Further, the vehicle 5B travels following the vehicle 5A. Since the lamp color of the signal of the pedestrian crossing P changes from flashing blue to red, the lights of the

vehicles

5A and 5B and the traffic lights ahead are also switched from blue to yellow and red. Therefore, the

vehicles

5A and 5B are rushing to pass through the intersection.
Furthermore, there is a building G2 between the route R2 and the route R1 and at the corner of the intersection that blocks the view of the route R1 and the route R2.

Here, there is a possibility of collision between the vehicle 5A turning left at the intersection toward the route R1 and the

pedestrians

7A and 7B on the roadway. In particular, since there is a building G2 that blocks the line of sight between the route R1 and the route R2, it is difficult to notice each other until the vehicle 5A and the

pedestrians

7A and 7B approach each other. .

If the vehicle 5A turns left and travels toward the

pedestrians

7A and 7B, the edge server 3 specifies the

pedestrians

7A and 7B as the collision prediction targets of the vehicle 5A and the collision prediction targets of the

pedestrians

7A and 7B. As a result, the vehicle 5A is specified. In addition, the attributes of the

pedestrians

7A and 7B are children (only the pedestrian 7B), and the signals are ignored. Furthermore, there is a building G2 that is a blind spot factor between the vehicle 5A and the

pedestrians

7A and 7B.

At this time, when the edge server 3 obtains an evaluation value when the vehicle 5A is an evaluation object, the pedestrian attribute, the presence / absence of a blind spot factor, and an addition value by signal ignorance are added to the evaluation value obtained from the collision prediction time. to add.
Thereby, the evaluation value of the

pedestrians

7A and 7B in the vehicle 5A.

pedestrians

7A and 7B to the

pedestrians

7A and 7B. Notice.

Further, also in the vehicle 5B, when the vehicle 5A notices the

pedestrians

7A and 7B on the pedestrian crossing P and decreases the speed, and both vehicles approach, the edge server 3 identifies the vehicle 5A as a collision prediction target of the vehicle 5B. As a result of the collision prediction, if the collision prediction time is short, the evaluation value is set to a large value. As a result, the edge server 3 notifies the vehicle 5B of information related to the collision prediction result of the vehicle 5A in the vehicle 5B.

As described above, the in-vehicle device 50 of the

vehicles

5A and 5B and the pedestrian terminal 70 of the

pedestrians

7A and 7B output information on the collision prediction result to the user of the own device based on the notification from the edge server 3.
Thereby, the edge server 3 can make the user of the vehicle 5A recognize in advance that a pedestrian crosses the pedestrian crossing P.
Further, the edge server 3 can make the

pedestrians

7A and 7B recognize in advance that the vehicle 5A appears from the right side of the pedestrian crossing P.

[Other Embodiments]
FIG. 22 is a diagram illustrating an aspect of information provision executed by a system according to another embodiment.
FIG. 22 is a flowchart illustrating an example of arithmetic processing according to another embodiment.
The edge server 3 of the present embodiment is configured to evaluate the comfort of movement of each evaluation object based on the dynamic information map M1 and obtain an evaluation value based on the comfort of future movement of each evaluation object. Has been. That is, the predicted traffic situation of each evaluation object predicted by the calculation unit 31a of the present embodiment is a situation indicating whether or not the future movement of the evaluation object is a comfortable movement.

More specifically, the edge server 3 divides each route in the service area into a plurality of unit areas, determines whether there is a factor that impairs comfort in each unit area, and determines comfort. Identify non-comfortable areas that have more than a certain amount of damage. The edge server 3 registers the determination result in the database and updates it as needed.
In the present embodiment, the factor that impairs comfort is, for example, the occurrence of traffic jams or the presence of a meandering pedestrian. If these factors exist above a certain level, the edge server 3 identifies the unit area as a non-comfort area.

Furthermore, the edge server 3 calculates | requires an evaluation value based on the positional relationship of an evaluation object and a non-comfort area. For example, the evaluation value is set according to the distance between the evaluation target and the non-comfort area.
This evaluation value is set to a larger value as the evaluation target and the non-comfort area are closer. When the evaluation target and the non-comfort area are close to each other, there is a high possibility that the evaluation target passes through the non-comfort area, and the comfort of future movement may be impaired. That is, the evaluation value of the present embodiment is set according to the possibility that the evaluation target passes through the non-comfort area.

When the evaluation value is equal to or greater than a predetermined threshold, the determination unit 31b notifies the evaluation target of information related to the non-comfort area.
And when approaching a non-comfort area, the in-vehicle device 50 of

vehicles

5A and 5B and the pedestrian terminal 70 of

pedestrians

7A and 7B send information about the non-comfort area based on the notification from the edge server 3. To the user.

In FIG. 22, each route R10, R11, R12, R13, R14 delimited by the intersection constitutes a unit area.
Of each route, a traffic jam occurs in route R11, and meandering

pedestrians

7A and 7B exist. With these events, the edge server 3 identifies the route R11 as a non-comfort area. It is assumed that other routes are not specified as non-comfort areas.

Here, the vehicle 5A traveling along the route R10 toward the intersection where the route R11 and the route R12 are connected is approaching the route R11 which is a non-comfort area. Then, it is assumed that the evaluation value of the vehicle 5A as the evaluation target increases as it approaches the route R11 that is a non-comfort area, and becomes equal to or higher than a predetermined threshold value.
In this case, the edge server 3 notifies the vehicle 5A, which is the evaluation target, of information related to the non-comfort area.

Further, the vehicle 5B traveling along the route R13 toward the intersection where the route R11 and the route R14 are connected is approaching the route R11 which is a non-comfort area. Then, it is assumed that the evaluation value of the vehicle 5B as the evaluation target increases as it approaches the route R11 that is a non-comfort area, and becomes equal to or greater than a predetermined threshold value.
Also in this case, the edge server 3 notifies the information regarding the non-comfort area to the vehicle 5B which is the evaluation target.

Based on the notification from the edge server 3, the in-vehicle device 50 of the vehicle 5 A or 5 B outputs information on the non-comfort area that is likely to pass in the future to the user of the own device as information on the predicted traffic information.

In FIG. 22, on the output screen V10 of the in-vehicle device 50 of the vehicle 5A, when entering the route R11, a display D10 indicating that a non-comfort area exists, an arrow D11 indicating a detour avoiding the non-comfort area, and the like Is displayed.
Further, on the output screen V11 of the in-vehicle device 50 of the vehicle 5B, when entering the route R13, a display D12 indicating that a non-comfort area exists, an arrow D13 indicating a detour avoiding the non-comfort area, and the like are displayed. Is done.

Thus, the edge server 3 can make the user of the vehicle 5A recognize in advance that a non-comfort area appears, and can maintain the comfort during movement for each evaluation object.
