  Next, the processing unit 2 determines whether or not to end the update processing of the area information AR according to the embodiment, for example, by turning off the power switch of the server device SV (step S6). (Step S6: YES), the update process is terminated as it is. On the other hand, in the determination of step S6, when the area information AR update process for another risk management area is continued (step S6: NO), the processing unit 2 returns to step S1 and step S2 and repeats the process described above. .

  Next, step S4 and step S5 will be specifically described.

That is, in step S4 and step S5, the processing unit 2 determines the area information based on the behavior data UPV and behavior data UPP transmitted from each vehicle-mounted device V and each pedestrian device P, for example, as follows. The AR itself and the corresponding transmission frequency information 59-1 are updated.
(A) Regarding the risk indicated by the risk information 59, the risk D as the area information AR is set to the accident rate set in advance corresponding to the child existing in the risk management area. Update to the multiplied value (see step S4).
(A) The risk level D is updated to a value obtained by multiplying the number of elderly people by an accident rate set in advance corresponding to the elderly people existing in the risk management area (see step S4).
(C) The area of the risk management area indicated by the risk management area information 52 is updated more widely as the risk D is higher (see step S4).
(D) The area of the risk management area is updated narrower as the risk D is lower (see step S4).
(E) With respect to the transmission frequency indicated by the transmission frequency information 59-1, the higher the risk level D is, the more the accident tendency information of the corresponding risk management area is transmitted to each in-vehicle device V or each pedestrian device P. The frequency is updated high (see step S5).
(F) Regarding the transmission frequency, the lower the risk level D is, the lower the frequency of transmitting the accident tendency information and the like of the corresponding risk management area to each in-vehicle device V or each pedestrian device P (step S5). reference).

  Here, with respect to step S4 and step S5, for example, the update table T illustrated in FIG. 7C is recorded in advance in the recording unit 5 of the server apparatus SV, and the processing unit is referred to the update table T. 2 may be configured to execute.

  That is, as the update item T1 for the “danger management area” itself, the above-described update of the risk D (above (A) to (I)) and the update of the area (above (U) and (E)). May be described, and the above-described step S4 may be executed with reference to this. In addition to the nursing home, elementary school or driving school, the kindergarten, park, and shopping street are described as the update item T2 for “facility”, and the above-described step S4 is executed with reference to this. May be. In addition, as an update item T3 for “time zone”, for example, the restriction of the traffic direction due to the change of the time zone of the lane restriction and the restriction of the approach direction to the intersection are described, and the above-described step S4 is executed with reference to this. You may comprise.

  Also, as a different aspect, as an update item T4 for “calling frequency”, depending on the rank of the risk D set in advance, a warning in the vehicle-mounted device V or the pedestrian device P (more specifically, a warning call) Information to change the frequency of the accident tendency information or the like is transmitted from the server device SV to the in-vehicle device V or the pedestrian device P. You may comprise. In addition, as the update item T5 for the “calling timing”, information for making the in-vehicle device V or the pedestrian device P alert more distantly as the rank of the risk D is higher in the accident tendency information or the like. In addition, the server device SV may be configured to transmit to the in-vehicle device V or the pedestrian device P. Furthermore, as an update item T6 for “movement speed”, when the speed of the vehicle on which the in-vehicle device V is mounted reaches a speed corresponding to the first near-miss information or the second near-miss information, the in-vehicle device V Information for alerting may be included in the accident tendency information or the like and transmitted from the server device SV to the in-vehicle device V. Finally, as an update item T7 for “direction”, the relationship between the position of the vehicle on which the in-vehicle device V is mounted and the position of the pedestrian carrying the pedestrian device P is the first near information or the first information. Information for making the vehicle-mounted device V and the pedestrian device P alert each other when the positional relationship corresponding to 2 near-miss information is included in the accident tendency information and the like from the server device SV. You may comprise so that it may transmit to V and the said pedestrian apparatus P.

(III) Traffic Accident Prevention Processing According to Embodiment Next, the traffic accident prevention processing according to the embodiment, which is executed in the traffic accident prevention system SS according to the above-described embodiment, will be specifically described with reference to FIG. To do.

  The traffic accident prevention process according to the embodiment is executed centering on the processing unit 2 of the server device SV, the processing unit 11 of the in-vehicle device V, and the processing unit 21 of the pedestrian device P. For example, a preset time Every time, the processing unit 2, the processing unit 11, and the processing unit 21 are started.

  The flowchart is shown in FIG. As the traffic accident prevention process according to the embodiment, first, the processing unit 21 of the pedestrian device P first requires a risk management area required for the pedestrian device P (for example, a risk management area in front of the traveling direction). The area information AR (refer to FIG. 4) and a designated area information request for requesting vehicle information VI for vehicles existing in and around the danger management area at that time are transmitted to the server SV (step S40). S10). On the other hand, the processing unit 11 of the in-vehicle device V includes the area information AR (see FIG. 4) of a risk management area (for example, a risk management area in front of the traveling direction) required in the in-vehicle device V at that time, At that time, a designated area information request for requesting vehicle information VI and pedestrian information PI for vehicles and pedestrians in and around the danger management area is transmitted to the server SV (step S30).

  Next, the processing unit 2 of the server device SV that has received the specified area information request from the in-vehicle device V or the pedestrian device P searches the recording unit 5 for the area information AR and the like indicated by each specified area information request. And the said search result is transmitted to the vehicle-mounted apparatus V or the pedestrian apparatus P which is the transmission origin of the said designation | designated area information request | requirement as designation | designated area information (step S26). Thereafter, the processing unit 2 determines whether or not to end the traffic accident prevention processing according to the embodiment, for example, when the power switch of the server device SV is turned off (step S27), and when it ends (step S27). : YES), the traffic accident prevention process is terminated as it is. On the other hand, when the traffic accident prevention process is continued in the determination in step S27 (step S27: NO), the processing unit 2 returns to step S25 and repeats the above-described process.

  On the other hand, the processing unit 21 of the pedestrian apparatus P that has received the specified area information (step S11) indicates an accident tendency or the like in the risk management area ahead in the traveling direction based on the received specified area information. Prior notice to be displayed on P is executed (step S12). Thereafter, the processing unit 21 monitors whether or not a pedestrian carrying the pedestrian device P has entered the danger management area (step S13). When the pedestrian has not yet entered the danger management area in the monitoring in step S13 (step S13: NO), the processing unit 21 executes the advance notification in step S12, for example, at regular intervals. On the other hand, when the pedestrian has entered the danger management area in the monitoring in step S13 (step S13: YES), the processing unit 21 is based on the risk information 59 included in the area information AR received in step S11. The risk level related process in the risk management area at that time is executed (step S14).

  Here, specifically, as the step S14, the processing unit 21 indicates, for example, that the vehicle information VI received in step S11 indicates that there is a vehicle moving at high speed in the danger management area, for example. As a value obtained by multiplying a vehicle parameter set in advance as a vehicle by an accident rate set in advance for the vehicle and dividing it by the distance between the pedestrian carrying the pedestrian device P and the vehicle, The risk level D (or alert level) as the risk management area at that time is calculated. Thereafter, the processing unit 21 determines whether or not the calculated degree of risk D (or alert level) is equal to or higher than a preset notification threshold. The fact is notified as the accident tendency using the display on the display 22, for example.

  Thereafter, the processing unit 21 proceeds to step S21 described later.

  On the other hand, the processing unit 11 of the in-vehicle device V that has received the specified area information (step S31) indicates an accident tendency or the like in the risk management area ahead of the traveling direction on the in-vehicle device V based on the received specified area information. Prior notice to be displayed is executed (step S32). At this time, the processing unit 11 may be configured to display the accident tendency information and the like on the display 12 together with the map corresponding to the received accident tendency information and the like. Thereafter, the processing unit 11 monitors whether or not the vehicle on which the in-vehicle device V is mounted has entered the danger management area (step S33). When the vehicle has not yet entered the danger management area in the monitoring in step S33 (step S33: NO), the processing unit 11 executes the advance notification in step S32, for example, at regular intervals. On the other hand, when the pedestrian has entered the risk management area in the monitoring in step S33 (step S33: YES), the processing unit 11 is based on the risk information 59 included in the area information AR received in step S31. The risk related processing in the risk management area at that time is executed (step S34).

  Here, specifically as the step S34, the processing unit 11 indicates that the pedestrian information PI received in step S31 indicates that, for example, children and elderly persons exist as pedestrians in the risk management area. The pedestrian parameter preset as the child and the accident rate preset for the child are respectively calculated to calculate the first multiplication value, and the pedestrian preset as the elderly A second multiplication value is calculated by multiplying the parameter and the accident rate set in advance for the elderly. Next, the processing unit 11 calculates a first division value obtained by dividing the first multiplication value by the distance between the vehicle on which the in-vehicle device V is mounted and the child, and the distance between the vehicle and the elderly person. To calculate a second division value obtained by dividing the second multiplication value. Thereafter, the processing unit 11 calculates a risk level D (or alert level) as the risk management area at that time as a value obtained by adding the calculated first divided value and the second divided value. Thereafter, the processing unit 11 determines whether or not the calculated risk D (or alert level) is equal to or higher than a preset notification threshold, and if it is equal to or higher than the notification threshold, The fact is notified as the accident tendency information using the display on the display 12, for example.

  Thereafter, the processing unit 11 proceeds to step S41 described later.

  Next, the processing unit 21 of the pedestrian device P monitors whether or not there is an in-vehicle device V capable of directly communicating with the pedestrian device P in parallel with the above steps S10 to S14. (Step S15). When the vehicle-mounted device V does not exist in the monitoring of step S15 (step S15: NO), the processing unit 21 proceeds to step S21 described later.

  On the other hand, the processing unit 11 of the in-vehicle device V monitors whether or not there is a pedestrian device P capable of directly communicating with the in-vehicle device V in parallel with the above steps S30 to S34 (steps). S35). When the said pedestrian apparatus P does not exist in the monitoring of step S35 (step S35: NO), the process part 11 transfers to step S41 mentioned later.

  On the other hand, when the in-vehicle device V and the pedestrian device P capable of directly communicating with each other are found in the monitoring in the step S15 and the step S35 (step S15: YES, step S35: YES), the direct communication is possible. The processing unit 21 of the pedestrian apparatus P and the processing unit 11 of the in-vehicle apparatus V start communication with each other, and confirm each other's existence and attributes (step S16, step S36).

  And the process part 21 of the pedestrian apparatus P compares the result of the said direct communication with the vehicle information VI received by said step S11, and the other party's vehicle currently communicating directly has preset requirements. It is determined whether or not the vehicle is a dangerous vehicle (step S17). As the determination in step S17, for example, a vehicle or the like moving at high speed in the direction of a pedestrian carrying the pedestrian apparatus P is determined as a dangerous vehicle (step S17: YES). If it is determined in step S17 that the partner vehicle currently in direct communication is not a dangerous vehicle (step S17: NO), the processing unit 21 proceeds to step S21 described later. On the other hand, if it is determined in step S17 that the other party's vehicle currently in direct communication is a dangerous vehicle (step S17: YES), the processing unit 21 next performs, for example, the update item T4, the update item T5, or the update item. A determination similar to the content described as one of T7 (see FIG. 7C) is made based on the vehicle information VI received in step S11, and whether or not the alerting timing for the dangerous vehicle has arrived. Determination is made (step S18). If it is determined in step S18 that the alerting timing has not yet arrived (step S18: NO), the processing unit 21 returns to step S16 and continues direct communication. On the other hand, when the alerting timing has come in the determination of step S18 (step S18: YES), the processing unit 21 performs necessary alerting using, for example, the display 22 (step S19). Thereafter, the processing unit 21 monitors whether or not the dangerous vehicle has been avoided by, for example, passing the dangerous vehicle (step S20). In the monitoring of step S20, when the dangerous vehicle is not avoided (step S20: NO), the processing unit 21 calls the attention continuously or intermittently (step S19). When the dangerous vehicle is avoided in the monitoring in step S20 (step S20: YES), the processing unit 21 prevents the traffic accident according to the embodiment by turning off the power switch of the pedestrian device P, for example. It is determined whether or not the process is to be ended (step S21). When the process is to be ended (step S21: YES), the traffic accident prevention process is ended as it is. On the other hand, when the traffic accident prevention process is continued in the determination of step S21 (step S21: NO), the processing unit 21 returns to step S10 and step S15 and repeats the above-described process.

  On the other hand, the processing unit 11 of the in-vehicle device V compares the result of the direct communication in step S36 with the pedestrian information PI received in step S31, and the other pedestrian who is currently communicating directly sets in advance. It is determined whether or not the person is a dangerous pedestrian having the required requirements (step S37). As the determination in step S37, for example, when a child or an elderly person is present in the traveling direction of the vehicle on which the vehicle-mounted device V is mounted, the child or the elderly person is determined as a dangerous pedestrian (step S37: YES). If it is determined in step S37 that the pedestrian of the other party who is currently communicating directly is not a dangerous pedestrian (step S37: NO), the processing unit 11 proceeds to step S41 described later. On the other hand, if it is determined in step S37 that the pedestrian of the other party who is currently communicating directly is a dangerous pedestrian (step S37: YES), the processing unit 11 then selects any of the update items T4 to T7, for example. (See FIG. 7C), the same determination as that described above is performed based on the pedestrian information PI received in step S31, and it is determined whether or not the alerting timing for the dangerous pedestrian has arrived. (Step S38). If it is determined in step S38 that the alerting timing has not yet arrived (step S38: NO), the processing unit 11 returns to step S36 and continues the direct communication. On the other hand, when the alerting timing has come in the determination of step S38 (step S38: YES), the processing unit 11 performs the necessary alerting using, for example, the display 12 (step S39). Thereafter, the processing unit 11 monitors whether or not the dangerous pedestrian has been avoided, for example, when the dangerous pedestrian has passed (step S40). In the monitoring of step S40, when the dangerous pedestrian is not avoided (step S40: NO), the processing unit 11 continuously or intermittently alerts the user (step S39). Further, in the monitoring of step S40, when the dangerous vehicle is avoided (step S40: YES), the processing unit 11 performs the traffic accident prevention processing according to the embodiment by turning off the power switch of the in-vehicle device V, for example. Is determined (step S41), and if it is to be ended (step S41: YES), the traffic accident prevention process is ended as it is. On the other hand, in the determination of step S41, when the traffic accident prevention process is continued (step S41: NO), the processing unit 11 returns to step S30 and step S35 and repeats the above-described process.

  Next, the effect of the area information AR update process according to the embodiment and the traffic accident prevention process according to the embodiment will be specifically described with reference to FIGS. 9 and 10.

  First, the effect of the update process of the area information AR according to the embodiment will be described with reference to FIG. Here, in the case where there is a road R as illustrated in FIG. 9A, when the vehicle C1 enters the intersection CR, for example, if a pedestrian warning W1 is displayed, the area information AR according to the embodiment If the update process is not executed, even if the vehicle C1 safely passes through the intersection CR, if the vehicle C1 enters the intersection CR again after that, the same warning W1 is displayed in the vehicle C1. It will be. Further, although a warning W2 for the pedestrian PS1 is displayed in the vehicle C2 that makes a left turn at the intersection CR, for example, when a new building BD is constructed, the pedestrian PS2 that appears from the shadow of the pedestrian PS2 is not in the vehicle C3. There is no alerting, and the vehicle C3 is “near” in relation to the pedestrian PS2.

  On the other hand, behavior data UPV (FIG. 7 (a)) indicating that the vehicle C1 has safely passed the intersection CR is transmitted to the server device SV. As a result, when the area information AR is updated, FIG. As illustrated in b), when the vehicle C1 enters the intersection CR again after that, the warning W1 is not displayed on the vehicle C1. In addition, the behavior data UPV and the behavior data UPP (see FIG. 7B) are transmitted to the server device SV that the vehicles C3 and the pedestrian PS2 have “near” experiences, and the area information AR is updated accordingly. Then, as illustrated in FIG. 9B, when there is a vehicle C3 that approaches the building BD again after that, a warning W3 for the pedestrian PS2 is newly displayed.

  Next, the effect of the traffic accident prevention process according to the embodiment will be described with reference to FIG. Here, when the risk management area A illustrated in FIG. 10A is set / displayed on the map displayed on the display 12, an elderly pedestrian PSO that can be a dangerous pedestrian is included therein. When the vehicle C is moving along the route R passing through the risk management area A, a warning W4 as illustrated in FIG. 10A is displayed as a prior notice in step S32. Is done. When a route change is requested along the warning W4, the processing unit 11 of the in-vehicle device V mounted on the vehicle C re-sets a new route RR avoiding the danger management area A, for example. May be.

  When the vehicle C advances from the state illustrated in FIG. 10A and moves to the position illustrated in FIG. 10B, the in-vehicle device V of the vehicle C is, for example, a walking carried by an elderly pedestrian PSO. Direct communication with the person terminal P (see step S16 and step S36 in FIG. 8) is started, and thereafter the alerting (step S17 to step S20 and step S37 to step S40 in FIG. 8) described with reference to FIG. 8 is executed. Thus, the vehicle C can safely pass through the danger management area A.

  As described above, according to the traffic accident prevention process according to the embodiment, the current position data indicating the position of each of a plurality of pedestrians and the above risk management before entering the risk management area to be careful about traffic. Area information AR related to the area is acquired by the in-vehicle device V, the risk management area corresponding to the area information AR is superimposed on the map and displayed on the display 12, and the risk management is performed based on each acquired current position data. When deciding whether to output an alert within the area, the alert can be output appropriately before and after entering the danger management area.

  Moreover, since the pedestrian information PI corresponding to a pedestrian is further acquired and it is determined whether warning output is output within a risk management area further based on the pedestrian apparatus PI, the output of the said warning is more appropriately displayed. Can be determined.

  Furthermore, since there is a possibility of contact between each pedestrian and the vehicle based on the current position data of each pedestrian, and when the pedestrian is an elderly person, an alert is issued more appropriately and effectively. Can be output.

  Furthermore, the area information AR including the weather, time zone, day of the week, and month / day is acquired, and based on these, it is determined whether or not to call attention in the risk management area, so that more appropriate warning is given. Or not. In addition, you may put temperature in this determination factor.

  In addition, since it is determined that alerting is performed when the degree of risk D (attention alerting level) is equal to or greater than the notification threshold, alerting can be appropriately performed according to the characteristics of the risk management area. The notification threshold may be configured to be set according to at least one of the current weather, time zone, day of the week, date, and temperature, for example. In this case, it is possible to call attention more appropriately.

  Furthermore, since the area information AR includes the accident tendency information, it is possible to call attention in a state in accordance with the actual situation regarding traffic.

  Moreover, since data, such as a mutual attribute, are exchanged by the direct communication between the pedestrian terminal P and the vehicle-mounted terminal V, it can be determined whether alerting is promptly performed in real time.

  In addition, the area information AR according to the embodiment may include event information indicating an event held in the corresponding area, information regarding events unique to the area, and the like. In this case, a warning can be output in a state of being more closely attached to the area.

  In the above-described embodiment, the direct communication is determined to be executed between the pedestrian device P and the vehicle-mounted device V without the server device SV being involved (step S15 in FIG. 8). In addition to this, by transmitting to the in-vehicle device V and the pedestrian device P information indicating that the direct communication should be started and information indicating the in-vehicle device V and the pedestrian device P as the other party. The server equipment SV may be configured to execute direct communication between the pedestrian device P and the vehicle-mounted device V.

  A program corresponding to the flowcharts shown in FIGS. 6 and 8 is recorded on a recording medium such as an optical disk or a hard disk, or obtained via a network such as the Internet, and this is used as a general-purpose microcomputer. It is also possible to cause the microcomputer or the like to function as the processing unit 2, the processing unit 11, or the processing unit 21 according to the embodiment.
