(2) In this case, it is preferable that the moving means identifying means identifies the type of the moving means from a vehicle having four or more wheels, and the association data identifies the type of the moving means from the vehicle, and associates the type of the moving means with the alert target person.

(3) In this case, it is preferable that the moving means identifying means identifies the type of the moving means from the saddle-ridden vehicle, the automobile, the bicycle, and the pedestrian, and the association data identifies the saddle-ridden vehicle, the automobile, the bicycle, and the pedestrian, and associates the type of the moving means with the alarm target person.

(4) In this case, it is preferable that the movement means identification means identifies the type of the movement means by distinguishing a registered vehicle in which the user is registered as a driver from a non-registered vehicle in which the user is not registered as a driver, and the alarm control means does not operate the alarm means when the identified type of the movement means is the non-registered vehicle.

(5) In this case, it is preferable that the moving means identification means, the positional information acquisition means, the storage means, and the alarm control means are constituted by a portable information terminal (for example, a portable information terminal 5,51,52,53 described later) owned by the user, the alarm means include an in-vehicle alarm device (for example, an in-vehicle navigation system 21 and an in-vehicle multifunction meter 31 described later) mounted on the registered vehicle, and the moving means identification means identifies the type of the moving means as the registered vehicle when the moving means can communicate with the in-vehicle alarm device in a short-range wireless manner.

(6) In this case, it is preferable that the alarm means includes a portable alarm device (for example, a wearable device 41 described later) to be worn by the user, and the alarm control means operates the portable alarm device when the type of the moving means is recognized as the bicycle or the hiking.

(8) In this case, the alarm control means preferably changes the operation mode of the alarm means based on the identification result and the position information.

(effects of the invention)

(1) In the present invention, the storage means stores association data associating a warning target person specified for a specific warning area with a type of movement means and a movement path in the warning area, the movement means identification means identifies the type of movement means of a user who is a traffic participant, and the position information acquisition means acquires position information on the position and the traveling direction of the user. When the user moves in the alert area and the alert object person is associated with the identification result and the position information of the type of the moving means at that time by the association data, the alert control means operates the alert means moving together with the user, thereby promoting the safety traffic of the user in the alert area. In particular, in the present invention, the category and the movement path of the movement means in the alert area are associated with the alert target person by the association data. Thus, for example, when the user moves by using a movement means of a category not associated with the alarm target person or when the user moves at a position not associated with the alarm target person, the alarm control means does not operate the alarm means. Thus, according to the present invention, unnecessary operation of the alarm means can be suppressed, so that safe traffic in the alert area can be assisted without annoying the user.

(2) In the present invention, the moving means identifying means identifies the type of moving means at the time of the user by distinguishing the saddle-type vehicle from the car, and the related data distinguishes the saddle-type vehicle from the car, and associates the type of moving means with the alarm target person. Thus, according to the present invention, unnecessary operations of the warning means of the user moving by the saddle-type vehicle or the warning means of the user moving by the car can be suppressed, and thus, the safety traffic in the guard area can be assisted without annoying the user.

(3) In the present invention, the moving means identifying means identifies the type of moving means of the user at the time of the step, and the related data identifies the type of the step, the car, the bicycle, and the step, and the type of the moving means is related to the alarm target person. Thus, according to the present invention, unnecessary operations of the warning means of the user moving by the saddle-type vehicle, the warning means of the user moving by the car, the warning means of the user moving by the bicycle, or the warning means of the user moving by the pedestrian can be suppressed, and thus the safety traffic in the guard area can be assisted without annoying the user.

(4) In the present invention, the mobile means identification means identifies the type of mobile means of the user at that time, by distinguishing between a registered vehicle in which the user is registered as a driver and a non-registered vehicle in which the user is not registered as a driver. Here, the registered vehicle is, for example, a private car. In addition, the unregistered vehicle is a public transportation vehicle such as a bus and a taxi. The warning control means does not operate the warning means when the type of the recognized moving means is a non-registered vehicle, that is, when the recognized user gets on the non-registered vehicle. Thus, according to the present invention, unnecessary work of the alarm means of the user who moves by the unregistered vehicle can be suppressed, so that the user does not feel tired.

(5) In the present invention, the mobile means identification means, the positional information acquisition means, the storage means, and the alarm control means are constituted by a portable information terminal owned by a user, and the alarm means includes an in-vehicle alarm device mounted on the registered vehicle, and the mobile means identification means identifies the type of the mobile means as the registered vehicle when the mobile means identification means can communicate with the in-vehicle alarm device in a short-distance wireless manner. Thus, according to the present invention, as long as the user holds the portable information terminal and enters the registered vehicle, the type of the moving means at that time is recognized as the registered vehicle, so that convenience can be improved.

(6) In the present invention, the alarm control means operates the portable alarm device worn by the user when the type of the identified moving means is a bicycle or a hiking. Thus, it is possible to assist the safe traffic of the user moving in the guard area by the bicycle or the hiking as the moving means.

(7) In the present invention, the portable information terminal includes a mobile means identification means, a location information acquisition means, a storage means, an alarm control means, and a communication means for transmitting and receiving information to and from the traffic management server. The traffic management server acquires a predetermined movement path of the user based on the position information transmitted by the communication means, extracts an area existing on the predetermined movement path from among the plurality of registered traffic areas as a warning area, and transmits association data predetermined for the warning area to the communication means. Thus, since only the associated data of the guard area existing on the predetermined moving path at that time is stored in the storage means of the portable information terminal, the necessary storage area can be minimized. In the present invention, the information on the plurality of registered traffic areas and the database storing the association data defined for each registered traffic area are managed by the traffic management server capable of wireless communication with the portable information terminals owned by the plurality of users, and thus the database can be updated in order, so that the latest association data can be provided to the portable information terminals of the respective users.

(8) In the invention, the alarm control means changes the working mode of the alarm means according to the identification result and the position information. Thus, the alarm means can be operated in an appropriate manner in accordance with the type of the movement means of the user at that time or the movement path in the guard area, so that the safety traffic in the guard area can be assisted to avoid an accident in the guard area.

Detailed Description

A traffic safety assistance system according to an embodiment of the present invention will be described below with reference to the drawings.

Fig. 1 is a diagram schematically showing a configuration of a traffic safety support system 1 according to the present embodiment and a part of a traffic area in which users 2,3,4, which are auxiliary objects of the traffic safety support system 1, move as traffic participants.

In the present embodiment, the traffic participant means a person who moves in a traffic area such as a road or a pedestrian by using any moving means such as a vehicle or a hiking. In fig. 1, the user 2 is a traffic participant moving in the lanes 55a,55b or the intersection 56 by using a four-wheel car as a moving means, the user 3 is a traffic participant moving in the lane 55a or the intersection 56 by using a motorcycle as a moving means, and the user 4 is a traffic participant moving in the pedestrian path 57 or the crosswalk 58 by using a pedestrian as a moving means.

In the present embodiment, the user is a traffic participant who has a portable information terminal (for example, a smart phone) to which an alert application program described later is installed and which can perform wireless communication with a traffic management server 6 described later, and who moves in a traffic area by using any moving means.

In the following description, a so-called left-hand traffic zone (that is, a traffic zone in which a vehicle must travel on the left side from the center of a road) is defined as an example, but the present invention is not limited thereto. That is, the present invention can also be applied to a traffic area in which a so-called right-hand traffic is defined (i.e., a traffic area in which a vehicle must travel on the right-hand side from the center of a road).

While the users 2,3,4 as traffic participants are moving in the guard area 9, which is a local traffic area including the past accident site a (for example, an area through which a person can pass for a few seconds when traveling at a legal speed such as an intersection, crosswalk, or junction), by using any moving means, the traffic safety support system 1 operates the alarm means that moves together with the users 2,3,4 according to specific conditions, thereby reminding the users 2,3,4 to pay attention and supporting safe and smooth traffic in the guard area 9.

In the example shown in fig. 1, the warning area 9 includes an intersection 56 where the lanes 55a,55b of the single-sided, single-lane, orthogonal to each other intersect, a portion in the vicinity of the intersection 56 among the lanes 55a,55b, and a crosswalk 58 existing in the vicinity of the intersection 56. In the guard area 9, there is a lot of accidents at the point a of a specific time period, and therefore, the traffic participants moving in the guard area 9 in the specific time period need to pay attention.

The traffic safety assistance system 1 includes: a mobile terminal group 20 including a portable information terminal owned by a user 2 using a four-wheel car as a moving means and a plurality of in-vehicle devices moving together with the user 2; a mobile terminal group 30 including a portable information terminal owned by a user 3 using a motorcycle as a moving means and an in-vehicle device moving together with the user 3; a mobile terminal group 40 including a portable information terminal owned by the user 4 taking a hiking as a moving means and a wearable terminal worn by the user 4; and a traffic management server 6 connected to the mobile terminal groups 20,30,40 so as to be capable of wireless traffic.

The traffic management server 6 is constituted by one or more computers communicably connected to the above-mentioned plurality of mobile terminal groups 20,30,40 (hereinafter, they will also be collectively referred to as "area terminals") that move together with the respective users 2,3,4 via a base station 59. More specifically, the traffic management server 6 is configured by a server connected to a plurality of area terminals via a base station 59, a network core, and the internet, an edge server connected to a plurality of area terminals via a base station 59 and a multi-access edge computing (Mulch-access Edge Computing, MEC) core, and the like.

Fig. 2 is a block diagram showing the construction of the traffic management server 6 and a plurality of mobile terminal groups 20,30,40 communicably connected to the traffic management server 6.

The mobile terminal group 20 that moves together with the user 2 using the four-wheel car as a moving means includes, for example, a portable information terminal 52 owned by the user 2, and a car navigation system 21 that registers the user 2 as a driver in advance in an alert application installed in the portable information terminal 52.

The in-vehicle navigation system 21 is configured by, for example, a global navigation satellite system (Global Navigation Satelite System, GNSS) receiver that determines the current position of the host vehicle based on signals received from the GNSS satellites, a storage device that stores map information, a navigation electronic control unit (Electronic Control Unit, ECU) that creates a movement path from the current position of the host vehicle to a destination, and makes the driver aware of information about the movement path by operating a display or a speaker, and the like.

As described above, the navigation ECU of the in-vehicle navigation system 21 can transmit and receive various information by short-range wireless communication (for example, wireless fidelity (Wi-Fi), bluetooth (registered trademark), and the like) with the portable information terminal 52 of the user 2 registered as the driver of the four-wheeled vehicle on which the navigation ECU is mounted. Accordingly, in a state where the user 2 holds the portable information terminal 52 while riding the four-wheeled vehicle, the functions of the portable information terminal 52 and the functions of the car navigation system 21 can be coordinated by the above-described short-range wireless communication. More specifically, various information may be shared between the portable information terminal 52 and the in-vehicle navigation system 21, or the in-vehicle navigation system 21 may be used as an in-vehicle warning device that operates in accordance with an instruction from the portable information terminal 52.

The mobile terminal group 30 that moves together with the user 3 using the motorcycle as a moving means includes, for example, a portable information terminal 53 owned by the user 3, and the in-vehicle multifunctional meter 31 that registers the user 3 as the driver's motorcycle in advance in an alarm application installed in the portable information terminal 53.

The in-vehicle multifunctional instrument 31 is configured by a digital display provided at a position that can be visually confirmed by the driver, a speaker provided in the vicinity of the digital display, a control device that allows the driver to know information on the state of the vehicle, such as the speed and gear of the vehicle, by operating the digital display or the speaker.

As described above, the control device of the in-vehicle multifunctional meter 31 can transmit and receive various information by short-range wireless communication (for example, wireless fidelity (Wi-Fi), bluetooth (registered trademark), and the like) with the portable information terminal 53 of the user 3 registered as the driver of the motorcycle on which the control device is mounted. Thus, in a state where the user 3 is riding on the motorcycle with the portable information terminal 53, the functions of the portable information terminal 53 can be cooperated with the functions of the in-vehicle multifunctional meter 31 by utilizing the above-mentioned short-range wireless communication.

More specifically, various information can be shared, for example, between the portable information terminal 53 and the in-vehicle multifunctional meter 31. Thus, the driver can use the mobile phone function of the portable information terminal 53 via the in-vehicle multifunctional meter 31, or can display map information or the like acquired by the navigation function of the portable information terminal 53 on the digital display. Further, the in-vehicle multifunctional meter 31 may be used as an in-vehicle alarm device that operates in accordance with an instruction from the portable information terminal 53.

The mobile terminal group 40 that moves together with the user 4 by walking includes, for example, a portable information terminal 54 owned by the user 4, and a wearable device 41 (e.g., glasses type, watch type, etc.) that registers the user 4 as a wearer in advance in an alarm application installed on the portable information terminal 54.

As described above, the wearable device 41 can transmit and receive various information by short-range wireless communication (for example, wireless fidelity (Wi-Fi), bluetooth (registered trademark), and the like) with the portable information terminal 54 of the user 4 registered as its wearer. Thus, in a state where the user 4 holds the portable information terminal 54 and wears the wearable device 41, the functions of the portable information terminal 54 and the functions of the wearable device 41 can cooperate with each other by using the above-described short-range wireless communication. More specifically, various information may be shared between the portable information terminal 54 and the wearable device 41, or the wearable device 41 may be used as a portable alarm device that operates according to an instruction from the portable information terminal 54.

The traffic management server 6 includes: a registered traffic area database 61 that holds information on a plurality of registered traffic areas registered in advance; and a communication unit 62 for transmitting and receiving various information to and from the mobile terminal groups 20,30,40 moving together with the respective users 2,3,4 moving in the traffic area as traffic participants.

The registered traffic area database 61 stores information on a plurality of registered traffic areas registered in advance and associated data specified for each of the registered traffic areas. In the registered traffic area database 61, a local traffic area (for example, an area through which a person can travel at a legal speed such as an intersection, a crosswalk, or a merge section, and the like, and which is defined within a specific distance from the past accident occurrence point) including the past accident occurrence point in a jurisdiction area (for example, a wide traffic area including a city, a prefecture, a single region, or the like) of the traffic management server 6 is registered as a registered traffic area.

Fig. 3 is a diagram schematically showing a part of the content of the registered traffic area database 61. As shown in fig. 3, the registered traffic area database 61 is composed of area base information on a plurality of registered traffic areas, and associated data specified for each of these registered traffic areas. Here, the area base information is constituted by, for example, a registration number, a name, a position, a road shape, and the like of the registered traffic area.

The association data defined for each registered traffic area associates one or more alert subjects defined for the registered traffic area with time periods, types of moving means, moving paths, and alert contents in the registered traffic area. The content of the related data will be described below with reference to fig. 4A and 4B.

Fig. 4A is a diagram schematically showing a registered traffic area 91 (named "Σ") registered as registration number 1 in the registered traffic area database 61 of fig. 3.

As shown in fig. 4A, the registered traffic region 91 includes an intersection 913 where a single-sided single-lane 911 extending north and south intersects a single-sided single-lane 912 extending east and west, a portion near the intersection 913 among the lanes 911,912, and a crosswalk 914 crossing the lane 912 in the north and south of the east side of the intersection 913.

In the registered traffic area 91, contact accidents between specific types of moving means occur at a point A1 in a specific time zone (as shown in fig. 3, points a to b). More specifically, there are many contact accidents (so-called right turn straight accidents) between vehicles including automobiles and straddle-type vehicles that enter the intersection 913 from the west and turn to the south and straddle-type vehicles that are going straight from the east to the west at the intersection 913. This is considered to be because, in a specific period of time (point a to point b), the driver of the vehicle entering the intersection 913 from the west can see the sun behind the vehicle entering the intersection 913 from the east, and thus it is particularly difficult to visually confirm a saddle-ride type vehicle smaller than an automobile.

Therefore, in the example shown in fig. 4A, it is necessary to alert both the user 2a of the four-wheel car that is to enter the intersection 913 from the west side and turn to the south side and the user 3a of the motorcycle that is to enter the intersection 913 from the east side and go straight to the west side, among the plurality of users 2a to 2e,3a to 3b,4A moving in the registered traffic area 91, in particular, to pay attention. In contrast, in the example shown in fig. 4A, regarding the user 2b who enters the intersection 913 from the north, the user 3b who enters the motorcycle at the intersection 913 from the north, the user 2c who enters the four-wheel vehicle at the intersection 913 from the south, the user 2d who enters the intersection 913 from the west and travels straight to the east, the user 2e who enters the intersection 913 from the east and travels straight to the west, the user 4A who is the pedestrian who is going to cross the crosswalk 914, and the like, it is considered that the possibility of occurrence of an accident is low even in a specific period of time, and therefore, the necessity of alerting these users 2b to 2e,3b,4A is low.

Accordingly, as shown in fig. 3, a first alert target person corresponding to the user 2a in the example of fig. 4A and a second alert target person corresponding to the user 3a in the example of fig. 4A are defined for the registered traffic zone 91. In addition, by means of the association data, the first alert object person and the time period for the registered traffic zone 91: a point to b point, and a moving path: right turn car entering from the west side, moving means: all vehicles including automobiles and straddle-type vehicles, and warning contents: note that a straight-ahead straddle-type vehicle is associated. In addition, by means of the association data, the second alert object person and the time period for the registered traffic zone 91: a point to b point, and a moving path: straight-going vehicles entering from the east side, moving means: saddle-ride type vehicle, and warning content: note that the vehicle is turning right in front, an association is established.

Fig. 4B is a diagram schematically showing a registered traffic area 92 (named "××intersection") registered as registration number 2 in the registered traffic area database 61 of fig. 3.

As shown in fig. 4B, the registered traffic area 92 includes an intersection 923 where a lane 921 of a single-side double lane extending north and south crosses a lane 922 of a single-side three lane extending east and west, a portion near the intersection 923 among the lanes 921,922, a portion near the intersection 923 among the sidewalk 924 adjacent to the lanes 921,922, and a crosswalk 925 crossing the lane 921 at the east and west of the intersection 923. As shown in fig. 4B, the implant 926 is provided between a lane 922 which enters from the east side with respect to the intersection 923 and a walk 924 adjacent to the lane 922.

In the registered traffic area 92, contact accidents between specific types of moving means are frequent at a point A2 near the east-side walkway 924 among the crosswalks 925. More specifically, there are many contact accidents (so-called left turn-around accidents) between a vehicle including an automobile and a straddle-type vehicle, which is to enter an intersection 923 from the east side and turn to the south side, and a bicycle or a pedestrian, which is to enter a crosswalk 925 from a sidewalk 924 from the east side and cross a lane 921. This is considered to be because, as shown in fig. 4B, the planting 926 is provided between the lane 922 and the pedestrian 924, and therefore it is difficult for the driver of the vehicle entering the intersection 923 from the east side on the lane 922 to visually confirm the bicycles or pedestrians moving in the same direction on the pedestrian 924, and it is also difficult for the driver of the bicycles or pedestrians moving on the pedestrian 924 to visually confirm the vehicle traveling on the lane 922.

Therefore, in the example shown in fig. 4B, it is necessary to alert, in particular, both the user 2f of the four-wheel car to enter the intersection 923 from the east side and turn to the south side and the user 4B of the bicycle to enter the crosswalk 925 from the east side walk 924 and cross the lane 921 from the east side to the west side, among the plurality of users 2f to 2g,3c,4B to 4c moving in the registered traffic area 92, to pay attention. On the other hand, in the example shown in fig. 4B, it is considered that the influence of the planting 926 as described above is small and the possibility of occurrence of an accident is low, and therefore, the necessity of warning these users 2g,3c,4c is low, regarding the user 2g of the four-wheel vehicle which is to enter the intersection 923 from the east side and turn right, the user 3c of the motorcycle which is to enter the intersection 923 from the east side and travel straight, the user 4c which is a pedestrian who is to traverse the crosswalk 925 from the west side to the east side, and the like.

Accordingly, as shown in fig. 3, a first alert target person corresponding to the user 2f in the example of fig. 4B and a second alert target person corresponding to the user 4B in the example of fig. 4B are defined for the registered traffic zone 92. In addition, by means of the association data, for the first alert object and time period of the registered traffic zone 92: from early to late, movement path: left-turn person entering from east side, moving means: all vehicles including automobiles and straddle-type vehicles, and warning contents: note the involvement in the left turn, and an association is established. In addition, by associating data, for a second alert object of the registered traffic zone 92, with a time period: from early to late, movement path: crosswalk traversers from east to west, and alarm content: note that the vehicle emerging from the right hand side, an association is established.

As described above, the types of moving means are classified into, for example, four types of hiking, bicycles, straddle-type vehicles (motorcycles, straddle-type three-wheeled vehicles, straddle-type four-wheeled vehicles, and the like) and automobiles (vehicles having four or more wheels, specifically, four-wheeled vehicles, buses, trucks, trailers, and the like) among the associated data stored in the registered traffic area database 61, and the types of moving means are associated with the alert target person.

Returning to fig. 2, the communication unit 62 of the traffic management server 6 acquires the predetermined movement paths of the respective users 2 to 4 based on the position information transmitted by the portable information terminals 52,53,54 owned by the respective users 2,3,4 existing in the jurisdiction. Further, the communication unit 62 extracts, from among the plurality of registered traffic areas registered in the registered traffic area database 61, a registered traffic area existing on the acquired predetermined movement path of each user 2 to 4, that is, a registered traffic area predicted to be moved by each user 2 to 4 in the near future, as a warning area for each user 2 to 4. The communication unit 62 transmits, from among the data stored in the registered traffic area database 61, area base information and associated data (hereinafter, collectively referred to as "alert area data") defined for the extracted alert area to the communication means 503 (see fig. 5 described below) of the portable information terminals 52 to 54 of the respective users 2 to 4.

Next, the functions of the portable information terminals 52 to 54 and the like will be described. Various applications such as a telephone application for realizing a mobile phone function, a navigation application for realizing a navigation function, and an alarm application for realizing an alarm function are installed in these portable information terminals 52 to 54. Thus, by activating the telephone application program in these portable information terminals 52 to 54 and the like, the mobile phone function is exhibited, and each of the users 2 to 4 can realize a voice call with another portable information terminal. In addition, in these portable information terminals 52 to 54, by starting the navigation application program, the navigation function is performed, and it is possible to acquire information on the current position, the traveling direction, and the like of each of the users 2 to 4, to create a predetermined moving path from the current position to a specific destination, or to use images, voices, and the like to cause each of the users 2 to 4 to recognize information on the created predetermined moving path.

Fig. 5 is a functional block diagram of an alert function realized by starting an alert application in the portable information terminal 5 in which the alert application is installed. In fig. 5, the mobile phone function implemented by the telephone application and the navigation function implemented by the navigation application are not shown.

The portable information terminal 5, which has activated the alert application, includes a moving means identification means 501, a position information acquisition means 502, a communication means 503, a storage means 504, and an alert control means 505.

The moving means identifying means 501 identifies the type of the current moving means of the user who owns the portable information terminal 5 by executing moving means identifying processing described later with reference to fig. 8A and 8B. The moving means identifying means 501 identifies the category of the moving means by dividing the category into four categories, such as hiking, bicycle, car and straddle type vehicle. The moving means identifying means 501 identifies a registered vehicle in which the user having the portable information terminal 5 is registered as a driver and a non-registered vehicle in which the user is not registered as a driver for the vehicle and the straddle-type vehicle.

The position information acquisition means 502 acquires information (hereinafter, they will also be collectively referred to as "position information") concerning the current position, the current traveling direction, the predetermined traveling path, and the like of the user who owns the portable information terminal 5. More specifically, the positional information acquisition means 502 acquires positional information by using, for example, the navigation function of the portable information terminal 5. As described with reference to fig. 2, the position information acquiring means 502 may acquire position information by using the function of the car navigation system 21 when cooperating with the function of the car navigation system 21.

The communication means 503 transmits the current location information of the user acquired by the location information acquisition means 502 to the communication unit 62 of the traffic management server 6. The communication means 503 receives the alert zone data of the alert zone transmitted by the communication means 62 of the traffic management server 6 as described above, and transmits the alert zone data to the storage means 504.

The storage means 504 stores the alert zone data of the alert zone transmitted by the communication means 503. The storage means 504 erases the stored guard area data after the user is separated from the guard area by a predetermined distance or more.

When the user moves within the alert area stored in the storage means 504, the alert control means 505 searches the associated data stored in the storage means 504 based on the current time, the identification result of the type of the moving means by the moving means identification means 501, the position information acquired by the position information acquisition means 502, and the like, thereby determining whether or not the user matches one of the one or more alert subjects specified for the alert area. In other words, the alarm control means 505 determines whether or not the user is moving in the guard area, and determines whether or not the user is associated with any one of the one or more alarm subjects defined for each guard area, based on the current time, the identification result of the type of the moving means, and the associated data of the position information.

When the user moves in the alert area and associates with the alert target person specified for the alert area, the alert control means 505 causes the alert means that moves together with the user to operate in accordance with the alert content specified by the association data. The alarm control means 505 does not operate the alarm means when the user does not move in the alert area, when it is determined that the user does not match the alarm target person, or when the type of the moving means is recognized as a non-registered vehicle by the moving means recognition means 501.

The alarm control means 505 causes the car navigation system 21 or the car multifunctional instrument 31 to operate as an alarm means when the mobile information terminal 5 and the car navigation system 21 or the car multifunctional instrument 31 can perform short-range wireless communication as described above. The alarm control means 505 causes the wearable device 41 to operate as an alarm means when the portable information terminal 5 and the wearable device 41 can perform the short-range wireless communication as described above, and causes a display or a speaker provided in the portable information terminal 5 to operate as an alarm means when the portable information terminal 5 and the wearable device 41 cannot perform the short-range wireless communication.

Fig. 6 and 7 are flowcharts showing a specific flow of alarm processing realized by starting an alarm application in the portable information terminal 5. After the alarm application is started, the alarm processing is repeatedly executed in the portable information terminal 5 at a specific control cycle.

First, in step ST1, the position information acquisition means 502 acquires position information of the user who owns the portable information terminal 5, and the process proceeds to step ST2. In step ST2, the positional information acquisition means 502 determines whether the user is moving based on the positional information acquired in step ST 1. If the determination result in step ST2 is YES, the position information acquisition means 502 proceeds to step ST3, and if NO, the alarm processing shown in fig. 6 and 7 ends.

In step ST3, the moving means identifying means 501 performs moving means identifying processing in accordance with the flow described later with reference to fig. 7, and shifts to step ST4. As will be described later, by executing this movement means identification process, the movement means identification means 501 can identify the category of the current movement means of the user as five categories, i.e., hiking, bicycle, registered car in which the user is registered as a driver, registered straddle-type vehicle in which the user is registered as a driver, and unregistered vehicle in which the user is not registered as a driver.

In step ST4, the moving means identifying means 501 determines whether or not the result of the moving means identifying process in step ST3 identifies that the type of the moving means is a non-registered vehicle. When the determination result in step ST4 is yes, that is, when it is determined that the user has mounted a public transportation vehicle as a non-registered vehicle, the moving means identifying means 501 ends the alarm processing shown in fig. 6 and 7 without operating the alarm means. If the determination result in step ST4 is no, that is, if the type of the moving means is a hiking, a bicycle, a registered car, or a straddle-type vehicle, the moving means identifying means 501 proceeds to step ST5.

In step ST5, the communication means 503 transmits the position information acquired in step ST1 to the communication unit 62 of the traffic management server 6, and shifts to step ST6. As described above, the communication unit 62 of the traffic management server 6 acquires the predetermined movement path of the user based on the position information transmitted by the portable information terminal 5, and extracts, as the alert area, an area existing on the predetermined movement path from among the plurality of registered traffic areas stored in the registered traffic area database 61. The communication unit 62 also returns alert zone data defined for the extracted alert zone to the communication means 503.

In step ST6, the communication means 503 determines whether or not the alert area data is received from the communication unit 62 of the traffic management server 6. If the determination result in step ST6 is no, the communication means 503 ends the alarm processing shown in fig. 6 and 7, and if yes, the process proceeds to step ST7.

In step ST7, the storage means 504 stores the alert area data received by the communication means 503, and proceeds to step ST8.

In step ST8, the alarm control means 505 determines whether the user is moving within the guard area by referring to the position information acquired in step ST1 and the guard area data stored in step ST7. If the determination result in step ST8 is no, the alarm control means 505 proceeds to step ST9, and if yes, proceeds to step ST11.

In step ST9, the alarm control means 505 determines whether or not the user is separated from the guard region by a specific distance or more by referring to the position information acquired in step ST1 and the guard region data stored in step ST7. If the determination result in step ST9 is no, the alarm control means 505 ends the alarm processing shown in fig. 6 and 7, and if the determination result in step ST9 is yes, the process proceeds to step ST10. In step ST10, the storage means 504 erases the warning area data stored in step ST7, and ends the alarm processing shown in fig. 6 and 7.

In step ST11, the alarm control means 505 acquires the current time, and proceeds to step ST12. In step ST12, the alarm control means 505 determines whether or not the identification result of the type of the moving means by the current time acquired in step ST11, the moving means identification process of step ST3, and the position information acquired in step ST1 are associated with any one of the one or more alarm subjects specified for the warning area by the association data stored in step ST 7. In other words, the alarm control means 505 searches the associated data based on the identification result of the current time and the type of the moving means and the position information, and thereby determines whether or not the user meets one or more alarm subjects specified for the alert area. If the determination result in step ST12 is no, that is, if the user does not match the alarm target person in the alert area during the current movement, the alarm control means 505 ends the alarm processing shown in fig. 6 and 7 without operating the alarm means.

If the determination result in step ST12 is yes, that is, if the user matches the alarm target person in the alert area during the current movement, the alarm control means 505 proceeds to step ST13. In step ST13, the alarm control unit 505 acquires, from the association data, the alarm content associated with the alarm target person determined to be in line with the user, and proceeds to step ST14. In step ST14, the alarm control means 505 causes the alarm means to operate in accordance with the alarm content acquired in step ST13. Here, the alarm control means 505 causes the wearable device 41 communicably connected to the portable information terminal 5 to operate as an alarm means when the type of the current user's movement means is identified as a walking or a bicycle, and causes the car navigation system 21 communicably connected to the portable information terminal 5 to operate as an alarm means when the type of the current user's movement means is identified as a registered car. When the type of the current user's movement means is recognized as the registered straddle-type vehicle, the warning control means 505 causes the in-vehicle multifunctional instrument 31 communicably connected to the portable information terminal 5 to function as a warning means.

Here, a specific example of the alarm processing shown in fig. 6 and 7 will be described by taking the situation shown in fig. 4A and 4B as an example.

In the alarm processing shown in fig. 6 and 7, when the user having the portable information terminal 5 is, for example, the user 2a of the four-wheel car in fig. 4A who is about to enter the intersection 913 from the west and turn right to the south, the alarm control means 505 determines that the user 2a matches the first alarm target person specified in the warning area of the registration number 1 from the associated data shown in fig. 3. In this case, the alarm control means 505 causes the car navigation system 21 to operate in accordance with the alarm content associated with the first alarm target person by the association data. More specifically, the warning control means 505 displays a message indicating that the user 2a is paying attention to the saddle-ride type vehicle traveling straight ahead on the display of the car navigation system 21 or sounds the message.

In the alarm processing shown in fig. 6 and 7, when the user having the portable information terminal 5 is, for example, the user 3a of the motorcycle in fig. 4A who is going to enter the intersection 913 from the east side and go straight to the west side, the alarm control means 505 judges that the user 3a matches the second alarm target person specified in the guard region of the registration number 1 by the associated data shown in fig. 3. In this case, the alarm control means 505 causes the in-vehicle multifunctional instrument 31 to operate in a manner corresponding to the alarm content with which the second alarm subject person has been associated by the association data. More specifically, the warning control means 505 displays a message of "notice vehicle in front right turn" on the display of the in-vehicle multifunctional meter 31 or sounds in voice, thereby reminding the user 3a of the notice.

In the alarm processing shown in fig. 6 and 7, when the user having the portable information terminal 5 is, for example, the user 2f of the four-wheel car in fig. 4B who is going to enter the intersection 923 from the east side and turns to the south side and turns to the left, the alarm control means 505 determines that the user 2f matches the first alarm target person specified for the warning area of the registration number 2, based on the associated data shown in fig. 3. In this case, the alarm control means 505 causes the car navigation system 21 to operate in accordance with the alarm content associated with the first alarm target person by the association data. More specifically, the warning control means 505 displays a message of "catch in left turn" on the display of the car navigation system 21 or sounds it in voice, thereby reminding the user 2f of the notice.

In the alarm processing shown in fig. 6 and 7, when the user having the portable information terminal 5 is, for example, the user 4B who is going to enter the crosswalk 925 from the east-side walk 924 and cross the bicycle on the lane 921 from the east to the west in fig. 4B, the alarm control means 505 determines that the user 4B matches the second alarm target person defined for the warning area of the registration number 2 based on the associated data shown in fig. 3. In this case, the alarm control means 505 causes the wearable device 41 to operate in a manner corresponding to the alarm content with which the second alarm subject person has been associated by the association data. More specifically, the alarm control means 505 displays a message of the content "notice vehicle appearing from the right-hand side" on the display of the wearable device 41 or sounds in voice, thereby reminding the user 4b of the notice.

As described above, in the alarm processing shown in fig. 6 and 7, it is preferable that the alarm control means 505 changes the operation mode according to the time, the identification result, and the position information when the alarm means is operated.

Fig. 8A and 8B are flowcharts showing a specific flow of the mobile means recognition processing.

First, in step ST21, the moving means identifying means 501 first determines whether or not a specific time has elapsed since the moving means identifying process was executed. When the determination result in step ST21 is yes, the moving means recognition means 501 ends the moving means recognition processing shown in fig. 8A and 8B so as to maintain the recognition result of the last moving means recognition processing performed. If the determination result in step ST21 is no, the moving means identifying means 501 proceeds to step ST22.

In step ST22, the moving means identifying means 501 calculates the current moving speed of the user based on the position information acquired in step ST1, and determines whether or not the moving speed is equal to or higher than a specific first speed threshold. The first speed threshold is a threshold defined for the movement speed in order to determine whether the user is moving by using the car or the straddle-type vehicle as a moving means. If the determination result in step ST22 is yes, the moving means identifying means 501 proceeds to step ST23, and if no, proceeds to step ST41.

In step ST23, the moving means identifying means 501 acquires the output of the acceleration sensor provided on the portable information terminal 5, and shifts to step ST24. In step ST24, the movement means recognition means 501 determines whether or not the engine sound or vibration specific to the saddle-ride type vehicle is detected based on the output of the acceleration sensor acquired in step ST 23. If the determination result in step ST24 is yes, the moving means identifying means 501 proceeds to step ST25, and if no, proceeds to step ST27.

In step ST25, the movement means identifying means 501 identifies that the type of the movement means is a saddle-ride type vehicle, and proceeds to step ST26. In step ST26, the mobile means recognition means 501 attempts to perform short-range wireless communication with the in-vehicle multifunctional meter 31, and proceeds to step ST30.

In step ST27, the moving means identifying means 501 identifies that the type of the moving means is an automobile, and proceeds to step ST28. In step ST28, the mobile means identification means 501 attempts to perform short-range wireless communication with the car navigation system 21, and proceeds to step ST30.

In step ST30, the moving means identifying means 501 determines whether or not the state of enabling the short-range wireless communication with the in-vehicle navigation system 21 or the in-vehicle multifunctional instrument 31 is established. If the determination result in step ST30 is yes, the moving means identifying means 501 proceeds to step ST31. In step ST31, the moving means identifying means 501 identifies the category of the moving means as a registered vehicle in which the user is registered as the driver, and proceeds to step ST32. In step ST32, the mobile means recognition means 501 sets an in-vehicle alarm device (i.e., the in-vehicle navigation system 21 or the in-vehicle multifunctional meter 31) capable of performing short-range wireless communication with the portable information terminal 5 as an alarm means, and ends the mobile means recognition process. If the determination result in step ST30 is no, the moving means identifying means 501 proceeds to step ST33. In step ST33, the moving means identifying means 501 identifies that the type of the moving means is a non-registered vehicle in which the user is not registered as a driver, and ends the moving means identifying process.

In step ST41, the movement means identifying means 501 calculates the current movement speed of the user based on the position information acquired in step ST1, and determines whether or not the movement speed is equal to or greater than a second speed threshold value defined lower than the first speed threshold value. The second speed threshold is a threshold defined for the movement speed in order to determine whether the user is moving by walking or by a bicycle. If the determination result in step ST41 is yes, the moving means identifying means 501 proceeds to step ST42, and if no, proceeds to step ST43.

In step ST42, the moving means identifying means 501 identifies that the type of the moving means is a bicycle, and the process proceeds to step ST44. In step ST43, the moving means identifying means 501 identifies that the type of the moving means is hiking, and the process proceeds to step ST44.

In step ST44, the mobile means identification means 501 attempts to perform short-range wireless communication with the wearable device 41, and proceeds to step ST45. In step ST45, the moving means identifying means 501 determines whether or not the state of enabling the near field communication with the wearable device 41 is established. If the determination result in step ST45 is yes, the moving means identifying means 501 proceeds to step ST46. In step ST46, the movement means recognition means 501 sets the wearable device 41 as the alarm means, and ends the movement means recognition processing. If the determination result in step ST45 is no, the moving means identifying means 501 proceeds to step ST47. In step ST47, the moving means recognition means 501 sets at least one of the display and the speaker provided in the portable information terminal 5 as the alarm means, and ends the moving means recognition processing.

According to the traffic safety support system 1 of the present embodiment, the following effects are achieved.

(1) In the traffic safety support system 1, the storage means 504 of the portable information terminal 5 stores association data associating a warning target person specified for a specific warning area with a type of movement means and a movement path in the warning area, the movement means identification means 501 identifies the type of movement means of a user as a traffic participant, and the position information acquisition means 502 acquires position information on the position and the traveling direction of the user. The alarm control means 505 is configured to operate the alarm means that moves together with the user when the user moves in the alert area and associates the identification result and the position information of the type of the moving means at that time with the alarm target person by the association data, thereby promoting the safety traffic of the user in the alert area. In particular, in the traffic safety support system 1, the category and the movement path of the movement means in the alert area are associated with the alert target person by the association data. Thus, for example, when the user moves by using a movement means of a category not associated with the alarm target person or when the user moves at a position not associated with the alarm target person, the alarm control means 505 does not operate the alarm means. Thus, according to the traffic safety support system 1, unnecessary operation of the alarm means can be suppressed, so that safe traffic in the guard area can be supported without annoying the user.

(2) In the traffic safety support system 1, the movement means identification means 501 identifies the type of movement means of the user at the time of identification from the vehicle, and the association data identifies the type of movement means from the vehicle, and associates the type of movement means with the person to be alerted. Thus, according to the traffic safety support system 1, unnecessary operations of the warning means of the user moving by the saddle-type vehicle or the warning means of the user moving by the car can be suppressed, and thus the safety traffic in the guard area can be supported without annoying the user.

(3) In the traffic safety support system 1, the movement means identification means 501 identifies the type of movement means of the user at the time of the user by the saddle-type vehicle, the car, the bicycle, and the pedestrian, and the related data identifies the saddle-type vehicle, the car, the bicycle, and the pedestrian, and associates the type of movement means with the alert target person. Thus, according to the traffic safety support system 1, unnecessary operations of the warning means of the user moving by the saddle-type vehicle, the warning means of the user moving by the car, the warning means of the user moving by the bicycle, or the warning means of the user moving by the pedestrian can be suppressed, so that the safety traffic in the guard area can be supported without annoying the user.

(4) In the traffic safety support system 1, the moving means identifying means 501 identifies the type of moving means of the user at that time, by distinguishing a registered vehicle in which the user is registered as a driver from a non-registered vehicle in which the user is not registered as a driver. Here, the registered vehicle is, for example, a private car. In addition, the unregistered vehicle is a public transportation vehicle such as a bus and a taxi. The warning control means does not operate the warning means when the type of the recognized moving means is a non-registered vehicle, that is, when the recognized user gets on the non-registered vehicle. Thus, according to the traffic safety support system 1, unnecessary work of the warning means of the user who moves by the unregistered vehicle can be suppressed, so that the user does not feel tired.

(5) In the traffic safety support system 1, the mobile means identification means 501, the positional information acquisition means 502, the storage means 504, and the warning control means 505 are constituted by the portable information terminal 5 owned by the user, and the warning means includes the in-vehicle warning devices such as the in-vehicle navigation system 21 and the in-vehicle multifunction meter 31 mounted on the registered vehicle, and the mobile means identification means 501 identifies the type of the mobile means as the registered vehicle when the mobile means can communicate with these in-vehicle warning devices in a short-range wireless manner. Thus, according to the traffic safety support system 1, if the user holds the portable information terminal and enters the registered vehicle, the type of the moving means at that time is recognized as the registered vehicle, so that convenience can be improved.

(6) In the traffic safety support system 1, when the identified type of the moving means is a bicycle or a hiking, the alarm control means 505 operates the wearable device 41 worn by the user. Thus, it is possible to assist the safe traffic of the user moving in the guard area by the bicycle or the hiking as the moving means.

(7) In the traffic safety support system 1, the portable information terminal 5 includes a moving means identification means 501, a position information acquisition means 502, a storage means 504, an alarm control means 505, and a communication means 503 for transmitting and receiving information to and from the traffic management server 6. The traffic management server 6 acquires a predetermined movement path of the user based on the position information transmitted by the communication means 503, extracts an area existing on the predetermined movement path from among the plurality of registered traffic areas as a warning area, and transmits association data predetermined for the warning area to the communication means 503. Accordingly, since only the associated data of the guard area existing on the predetermined moving path at that time is stored in the storage means 504 of the portable information terminal 5, the necessary storage area can be minimized. In the traffic safety support system 1, the registered traffic area database 61 storing information on a plurality of registered traffic areas and associated data defined for each registered traffic area is managed by the traffic management server 6 capable of wireless communication with the portable information terminals 5 owned by a plurality of users, whereby the registered traffic area database 61 can be updated in sequence, so that the latest associated data can be provided to the portable information terminals 5 of the respective users.

(8) In the traffic safety support system 1, the alarm control means 505 changes the operation mode of the alarm means based on the identification result and the position information. Thus, the alarm means can be operated in an appropriate manner in accordance with the type of the movement means of the user at that time or the movement path in the guard area, so that the safety traffic in the guard area can be assisted to avoid an accident in the guard area.

While the above description has been given of the embodiment of the present invention, the present invention is not limited to this. The construction of the details may be appropriately changed within the gist of the invention.
