In the following, disaster is a general term for fires, accidents, etc., and emergency vehicles (fire engines, ambulances, police cars, etc.) need to be dispatched.

  FIG. 1 is a configuration diagram of a disaster response system 1000 according to the embodiment. The disaster response system 1000 includes a road traffic control device 1 and a vehicle control device 2.

  The expressway entrance 3 is provided with an ETC (Electronic Toll Collection) radio device 31, an expressway entrance camera 32, and an expressway entrance control device 33. The ETC wireless device 31 reads vehicle identification information (for example, onboard equipment ID (Identifier)), which is information for identifying the vehicle C, from the vehicle C. The highway entrance camera 32 photographs the vehicle C. The highway entrance control device 33 transmits the vehicle identification information read by the ETC wireless device 31 and the image taken by the highway entrance camera 32 to the road traffic control device 1.

  Further, a tunnel entrance roadside wireless device 41, a tunnel entrance camera 42, and a tunnel entrance control device 43 are provided beside the road R at the entrance of the tunnel # 1 (roadside). The tunnel entrance roadside apparatus 41 reads the vehicle identification information from the vehicle C. The tunnel entrance camera 42 photographs the vehicle C. The tunnel entrance control device 43 transmits the vehicle identification information read by the tunnel entrance roadside wireless device 41 and the image taken by the tunnel entrance camera 42 to the road traffic control device 1.

  A tunnel exit roadside wireless device 51, a tunnel exit camera 52, and a tunnel exit control device 53 are provided beside the road R at the exit of the tunnel # 1 (roadside). The tunnel exit roadside apparatus 51 reads vehicle identification information from the vehicle C. The tunnel exit camera 52 photographs the vehicle C. The tunnel exit control device 53 transmits the vehicle identification information read by the tunnel exit roadside wireless device 51 and the image taken by the tunnel exit camera 52 to the road traffic control device 1.

  The road traffic control device 1 is, for example, a computer system generally called a road traffic control system. Although the road traffic control device 1 is shown as a single computer device in FIG. 1 for the sake of brevity of explanation, it may be realized by a plurality of computer devices. The road traffic control device 1 includes a processing unit 11, a storage unit 12, a display unit 13, an input unit 14, and a communication unit 15.

  The processing unit 11 controls the overall operation of the road traffic control device 1 and realizes various functions of the road traffic control device 1. The processing unit 11 includes, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). The CPU comprehensively controls the operation of the road traffic control device 1. The ROM is a storage medium that stores various programs and data. The RAM is a storage medium for temporarily storing various programs and rewriting various data. The CPU executes a program stored in the ROM, the storage unit 12 or the like using the RAM as a work area (working area). The processing unit 11 includes a feature amount calculation unit 111, a vehicle identification unit 112, a vehicle management information creation unit 113, a vehicle position estimation unit 114, a disaster position identification unit 115, a correspondence information creation unit 116, a communication control unit 117, and display control. Part 118 is provided.

  The feature amount calculation unit 111 calculates the feature amount of the vehicle C based on the captured image of the vehicle C transmitted from the expressway entrance control device 33. As the characteristic amount of the vehicle C, for example, the color and shape of the vehicle body, the license plate, the number of passengers, the age, the estimated value of sex, and the like can be cited. Similarly, the feature quantity calculation unit 111 is based on the photographed image of the vehicle C transmitted from the tunnel entrance control device 43 and the photographed image of the vehicle C transmitted from the tunnel exit control device 53. Calculate the amount.

  The vehicle identification unit 112 identifies the vehicle C using the feature amount calculated by the feature amount calculation unit 111. For example, the vehicle identification unit 112 calculates the feature amount calculated from the captured image of the vehicle C transmitted from the tunnel entrance control device 43 and the captured image of the vehicle C transmitted from the tunnel exit control device 53 thereafter. If the obtained feature amounts are the same (including those close to a certain extent, the same applies hereinafter), the vehicles C are identified as the same.

  The vehicle management information creation unit 113 uses the information of the vehicle C identified by the vehicle identification unit 112 to determine the passing date and time for each vehicle C at each point where the cameras 32, 42, 52 on the road R are installed. Create vehicle management information to manage.

  Here, FIG. 2 is a data configuration diagram of the vehicle management information of the embodiment. As shown in FIG. 2, the vehicle management information according to the embodiment includes items of a vehicle ID, a feature amount, and a passage date and time at each point.

  The vehicle ID is an identification number for uniquely identifying the vehicle C. The vehicle management information creation unit 113 stores the feature amount calculated by the feature amount calculation unit 111 in the feature amount item. Further, the vehicle management information creation unit 113 determines the passage date and time of each point (highway entrance, tunnel # 1 entrance, tunnel # 1 exit,...), The expressway entrance control device 33, the tunnel entrance control device 43, the tunnel. Based on information (vehicle identification information, captured image) transmitted from the exit control device 53 and information identified by the vehicle identification unit 112, information on the date and time when each vehicle C passed through each point is stored. The vehicle management information is stored in the storage unit 12.

  Returning to FIG. 1, the vehicle position estimation unit 114 estimates the position of each vehicle C present in the tunnel # 1. Specifically, the vehicle position estimation unit 114 estimates the position of each vehicle C existing in the tunnel # 1 using the vehicle management information described above. For example, the vehicle position estimation unit 114 calculates an average speed for each time zone from the time when each vehicle C passes through the tunnel # 1 and the distance of the tunnel # 1, and exists in the tunnel # 1 using the average speed. The position for each vehicle C is estimated.

  The disaster location identifying unit 115 identifies the location of the disaster that occurred in tunnel # 1. Specifically, the disaster location specifying unit 115 occurred in tunnel # 1 based on information obtained from a camera in tunnel # 1 (in-tunnel camera 81 in FIG. 3), a fire detector (not shown), and the like. Identify the location of the disaster.

  Here, FIG. 3 is an explanatory diagram illustrating a situation when a fire occurs in the tunnel # 1 in the embodiment. As shown in FIG. 3, when a fire occurs in the tunnel # 1, it is considered better to divide the tunnel # 1 into a plurality of areas in the traveling direction of the vehicle C and to divide the correspondence for each area. Of the vehicles C, vehicles C5 and C6 are inflamed due to a traffic accident. Also, smoke is generated along with the fire.

  First, regarding the vehicle C7 in the front area A3 before the fire occurrence position (right in FIG. 3), it is preferable to continue traveling and exit from the tunnel # 1. The vehicle C8 has already exited from the tunnel # 1. Further, for the vehicle C existing behind the fire occurrence position (left in FIG. 3), the vehicle C1 in the vehicle non-dense area A1 with low vehicle density does not hinder the progress of the emergency vehicle. Vehicles C2, C3, and C4 in the high-density vehicle dense area A2 hinder the progress of the emergency vehicle.

  Based on such circumstances, the correspondence information creation unit 116 is based on at least one of the distance from the position of the fire (disaster) in the tunnel # 1 and the density of the vehicle C in the tunnel # 1. Thus, for each area in the tunnel # 1, correspondence information in which correspondence control for the on-site arrival of the emergency vehicle with respect to the vehicle C is set. The correspondence control includes, for example, control for unlocking the door of the vehicle C and control for moving the vehicle C to the end of the road by automatic driving. The correspondence information is stored in the storage unit 12.

  Here, FIG. 4 is a data configuration diagram of correspondence information according to the embodiment. As shown in FIG. 4, the correspondence information of the embodiment includes the distance from the entrance of the tunnel # 1 (0 to 100 m (vehicle non-dense area A1), 100 to 400 m (vehicle dense area A2), 400 to 700 m (front). Area A3)) is composed of the following items: dense / non-dense (only behind the fire occurrence position), presence / absence of an unlock / automatic operation instruction as response control, and a display message.

  The correspondence information creation unit 116 determines the tunnel # 1 based on the position of each vehicle C existing in the tunnel # 1 estimated by the vehicle position estimation unit 114 and the position of the fire identified by the disaster position identification unit 115. The interior can be divided into a vehicle non-dense area A1, a vehicle dense area A2, and a front area A3.

  The correspondence information creation unit 116 sets the item of presence / absence of an instruction of unlocking / automatic driving to “none” for the non-crowded area A1. This is because this area is far from the location where the fire occurred and it is not necessary for the passengers of the vehicle C to get off, and the congestion of the vehicles C is low, so that each vehicle C prevents the emergency vehicles from arriving on site. This is due to the low necessity for response control. Correspondingly, the correspondence information creation unit 116 displays a display message for the vehicle non-crowded area A1 as “It is far from the fire. Please bring the vehicle to the end of the road so that emergency vehicles can pass easily.” Set.

  Also, the correspondence information creation unit 116 sets the item of presence / absence of an instruction of unlocking / automated driving to “present” for the vehicle crowded area A2. This is because this area is close to the location where the fire occurred and the passengers of the vehicle C need to get off, and because the density of the vehicles C is high, each vehicle C prevents the emergency vehicles from arriving at the scene. This is because there is a high need for response control. Correspondingly, the correspondence information creation unit 116 sets the display message “Close to fire. Please get off the vehicle and evacuate with the key on.” For the vehicle congestion area A2.

  Also, the correspondence information creation unit 116 sets the item of presence / absence of an instruction of unlocking / automated driving to “None” for the front area A3. This is because this area is ahead of the fire occurrence position, and the vehicle C existing here should continue to travel and exit from the tunnel # 1. Correspondingly, the correspondence information creation unit 116 sets the display message “fire is behind. Please drive the vehicle and get out of the tunnel” for the front area A3.

  Returning to FIG. 1, the communication control unit 117 controls communication with an external device by the communication unit 15. For example, the communication control unit 117 transmits the correspondence information in the storage unit 12 to the vehicle C in the tunnel # 1. Here, as shown in FIG. 3, a mobile radio base station 6 and an in-tunnel radio base station 7 (radio re-broadcasting facility or the like) are provided near the entrance of tunnel # 1 (left side in FIG. 3).

  The mobile radio base station 6 transmits / receives information to / from a mobile terminal (smart phone, tablet terminal, etc.) possessed by a passenger of the vehicle C in the tunnel # 1 by mobile radio communication. The in-tunnel radio base station 7 communicates with a communication device (vehicle control device 2) mounted on the vehicle C in the tunnel # 1 by in-tunnel radio communication using the in-tunnel radio antenna 71 installed in the tunnel # 1. Etc.) and send / receive information.

  And the communication control part 117 transmits the corresponding information of the memory | storage part 12 to the vehicle C in tunnel # 1 using in-tunnel wireless communication, or the passenger | crew of the vehicle C in tunnel # 1 using mobile wireless communication Can be transmitted to a mobile terminal owned by. Note that the correspondence information received by the mobile terminal may be transferred to the vehicle control device 2.

  Further, the communication control unit 117 obtains information for each area of the correspondence information from the information board 82 (FIG. 3) installed in the corresponding area in the tunnel # 1 and the corresponding area in the tunnel # 1. May be transmitted to at least one of the portable terminals owned by the passengers of the vehicle C existing in the vehicle. For example, the communication control unit 117 transmits the information of the display message of the vehicle non-dense area A1 in the correspondence information to the information board 82 installed in the corresponding area in the tunnel # 1. Then, on the information board 82 installed in the non-congested area A1, the message “It is far from the fire. Please bring the vehicle to the end of the road so that emergency vehicles can pass easily” is displayed. The driver or the like of the vehicle C in the area A1 can act appropriately by looking at the display.

  Further, for example, the communication control unit 117 transmits the information of the display message of the vehicle crowded area A2 in the correspondence information to the mobile terminal possessed by the passenger of the vehicle C existing in the corresponding area in the tunnel # 1. Then, it will be displayed on the mobile device as “It is close to the fire. Please get off the vehicle with the key on and evacuate”, and the passenger who owns the mobile device will act appropriately by looking at the display. can do.

  Further, for example, the communication control unit 117 transmits the information of the display message of the front area A3 in the correspondence information to the portable terminal possessed by the passenger of the vehicle C existing in the corresponding area in the tunnel # 1. Then, “The fire is behind. Please drive the vehicle and get out of the tunnel.” Is displayed on the mobile terminal, and the passenger (driver, etc.) who owns the mobile terminal sees the display and Can act.

  The display control unit 118 performs control to display various information on the display unit 13.

  The storage unit 12 is a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive). The storage unit 12 stores vehicle management information, correspondence information, vehicle video information (described later in FIG. 6), and the like.

  The display unit 13 is a means for displaying information, and is, for example, a liquid crystal display device (LCD (Liquid Crystal Display)), an organic EL (Electro-Luminescence) display device, or the like. The input unit 14 is a unit that receives a user operation, and is, for example, a keyboard, a mouse, or the like. The communication unit 15 is a communication interface for communicating with an external device.

  Next, the vehicle control device 2 will be described. The vehicle control device 2 is a computer device mounted on the vehicle C, and includes a processing unit 21, a storage unit 22, a display unit 23, an input unit 24, a communication unit 25, and a photographing unit 26. .

  The processing unit 21 controls the overall operation of the vehicle control device 2 and realizes various functions of the vehicle control device 2. The processing unit 21 includes, for example, a CPU, a ROM, and a RAM. The CPU comprehensively controls the operation of the vehicle control device 2. The ROM is a storage medium that stores various programs and data. The RAM is a storage medium for temporarily storing various programs and rewriting various data. The CPU executes a program stored in the ROM, the storage unit 22 or the like using the RAM as a work area (working area). The processing unit 21 includes a host vehicle position calculation unit 211, a correspondence determination unit 212, an unlock control unit 213, an automatic operation control unit 214, an imaging control unit 215, a communication control unit 216, and a display control unit 217.

  The own vehicle position calculation unit 211 calculates the position of the own vehicle in the tunnel # 1. The own vehicle position calculation unit 211 calculates the position of the own vehicle in the tunnel # 1 through communication with the in-tunnel wireless base station 7 via the in-tunnel wireless antenna 71, but is not limited thereto.

  The correspondence determination unit 212 determines the presence / absence of correspondence control of the host vehicle based on the correspondence information stored in the storage unit 22 and the position of the host vehicle calculated by the host vehicle position calculation unit 211. For example, if the correspondence information is shown in FIG. 4 and the position of the own vehicle is 50 m from the entrance of the tunnel # 1, the own vehicle exists in the non-crowded area A1 having a distance from the entrance of 0 to 100 m. Since the presence / absence of the unlock / automatic driving instruction is “None”, the correspondence determination unit 212 determines that there is no corresponding control of the own vehicle. Further, for example, when the correspondence information is shown in FIG. 4 and the position of the own vehicle is 350 m from the entrance of the tunnel # 1, the own vehicle exists in the vehicle dense area A2 having a distance of 100 to 400 m from the entrance. Thus, since the presence / absence of the unlock / automatic driving instruction is “present”, the correspondence determination unit 212 determines that the corresponding control of the own vehicle is present.

  The unlocking control unit 213 executes control for unlocking the door of the own vehicle when the correspondence determining unit 212 determines that the corresponding control of the own vehicle is present.

  The automatic driving control unit 214 executes control for moving the own vehicle to the end of the road by automatic driving when the correspondence determining unit 212 determines that the corresponding control of the own vehicle is present. The automatic driving control unit 214 is possible when the own vehicle originally has an automatic driving function.

  The imaging control unit 215 controls the imaging unit 26 to acquire an image. The photographing unit 26 is a means for photographing the surroundings, for example, a digital camera.

  The communication control unit 216 controls communication with an external device by the communication unit 25. The communication control unit 216 receives the correspondence information from the road traffic control device 1 using, for example, either in-tunnel wireless communication or mobile wireless communication, and stores it in the storage unit 22. In addition, the communication control unit 216 transmits an image captured by the imaging unit 26 to the road traffic control device 1.

  The display control unit 217 performs control to display various information on the display unit 23.

  The storage unit 22 is a storage device such as an HDD or an SSD. The storage unit 22 stores correspondence information and the like. The display unit 23 is a means for displaying information, such as a liquid crystal display device or an organic EL display device. The input unit 24 is a unit that receives a user operation, and is, for example, a button or a touch panel. The communication unit 25 is a communication interface for communicating with an external device.

  Next, the process which the vehicle control apparatus 2 performs is demonstrated. FIG. 5 is a flowchart illustrating processing executed by the vehicle control device 2 according to the embodiment. When a fire occurs in the tunnel # 1, in the road traffic control device 1, the vehicle position estimating unit 114 estimates the position of each vehicle C existing in the tunnel # 1, and the disaster position specifying unit 115 determines the position of the fire. The correspondence information creation unit 116 creates correspondence information (FIG. 4), and the communication control unit 117 transmits the correspondence information to the vehicle control device 2 via the communication unit 15.

  In the vehicle control device 2, the communication control unit 216 receives the correspondence information from the road traffic control device 1 via the communication unit 25 and stores it in the storage unit 22 (step S1).

  Next, the own vehicle position calculation unit 211 calculates the position of the own vehicle (step S2).

  Next, the correspondence determination unit 212 determines the presence / absence of correspondence control of the host vehicle based on the correspondence information stored in the storage unit 22 and the position of the host vehicle calculated by the host vehicle position calculation unit 211. (Step S3) If “Yes”, the process proceeds to Step S4. If “No”, the process is terminated.

  In step S4, the vehicle control device 2 executes response control. For example, the unlock control unit 213 performs control to unlock the door of the host vehicle. In addition, the automatic driving control unit 214 executes control for moving the own vehicle to the end of the road by automatic driving.

  Next, with reference to FIG. 6, a case where the vehicle C captures the surroundings in the tunnel # 1 and transmits the image to the road traffic control device 1 will be described. FIG. 6 is an explanatory diagram illustrating a situation in which the vehicle C photographs the surroundings in the tunnel # 1 and transmits the image to the road traffic control device 1 in the embodiment.

  In the example illustrated in FIG. 6, in the vehicle C3, the shooting control unit 215 controls the shooting unit 26 to acquire an image of fire in the tunnel # 1. And the communication control part 216 of the vehicle C3 transmits the image image | photographed by the imaging | photography part 26 to the road traffic control apparatus 1 via the radio | wireless antenna 83 in a tunnel, and the control apparatus 84 in a tunnel. The trigger that the vehicle C3 acquires an image and transmits it to the road traffic control device 1 in this way may be, for example, an image transmission request from the road traffic control device 1 to the vehicle C3, but is not limited thereto.

  Next, with reference to FIG. 7, the case where an emergency vehicle heads for the fire scene in tunnel # 1 is demonstrated. FIG. 7 is an explanatory diagram illustrating a state in which the emergency vehicle C9 heads for the fire in tunnel # 1 in the embodiment.

  In the example of FIG. 7, the vehicle C1 moves to the end of the road R by the driver. Of the vehicles C2 to C4, for example, the vehicle C2 has no automatic driving function, and the vehicles C3 and C4 have an automatic driving function. Then, the vehicles C3 and C4 move to the end of the road R by automatic driving. The vehicle C2 does not have an automatic driving function and cannot move to the end of the road R by automatic driving, but the door is unlocked by unlocking control. Therefore, the member M who gets off the emergency vehicle C9 can get on the vehicle C2 whose door is unlocked with the key attached, and can move the vehicle C2 to the end of the road R.

  Thus, according to the disaster response system 1000 of this embodiment, when a disaster occurs in the tunnel # 1 for the vehicle, it is possible to support the smooth on-site arrival of the emergency vehicle C9. Hereinafter, first, the operation and effect of the disaster response system 1000 of this embodiment when compared with the prior art will be described.

  In the prior art, for example, a plurality of fire detection means are provided at predetermined intervals in the tunnel, and the vehicle number is read by a camera placed at the entrance of the tunnel to estimate the position of the vehicle in the tunnel at the time of the tunnel fire. There is a method of performing appropriate evacuation guidance for a driver or the like with a plurality of various information terminals provided in the vehicle. However, this method has the following three problems.

(1) If a fire or the like occurs in the tunnel, the driver can be evacuated, but the vehicle cannot be controlled. For this reason, a driver | operator evacuates with the door of a vehicle locked, and possibility that the vehicle may become the hindrance to the spot arrival of an emergency vehicle cannot be reduced.
(2) Flexible evacuation guidance according to the density of vehicles in the tunnel and the distance from the fire is not provided, but only uniform evacuation guidance is provided.
(3) As information transmission means to the vehicle, there are a radio, a mobile phone, a car navigation device, and the like.

  On the other hand, according to the disaster response system 1000 of the present embodiment, the following effects are obtained. First, regarding the above (1), when a fire or the like occurs in the tunnel # 1, the vehicle unlock control and the automatic operation control can be performed so that the emergency vehicle can easily reach the site. Therefore, a vehicle driver who encounters a disaster in tunnel # 1 need only consider his / her evacuation, and does not need to be aware of vehicle unlocking confirmation or moving to the end of the road. There are advantages.

  Further, regarding (2) above, it is possible to flexibly respond to the density of vehicles in the tunnel # 1 and the distance from the fire. Further, regarding (3) above, in tunnel # 1, communication is reliably performed between the road traffic control device 1 and the vehicle control device 2 by using either in-tunnel wireless communication or mobile wireless communication. It can be carried out.

  In addition, the following effects can be obtained. For example, by using the correspondence information in which the correspondence control for the on-site arrival of the emergency vehicle with respect to the vehicle C is used for each area in the tunnel # 1, the correspondence control is performed only for the vehicle C having a high necessity for the correspondence control. be able to. For example, it is not preferable from the viewpoint of theft prevention or the like to perform the unlocking control even to the vehicle C where the necessity of the corresponding control is low.

  Further, the road traffic control device 1 uses the information board 82 (FIG. 3) installed in the corresponding area in the tunnel # 1 and the corresponding information in the tunnel # 1 in the corresponding information in the tunnel # 1. By transmitting to at least one of the portable terminals possessed by the passengers of the vehicle C existing in the area, the person who sees the information can act appropriately.

  Further, in order to identify the vehicle C, it is possible to more reliably identify the vehicle C by using a feature amount including a plurality of pieces of information such as the color, shape, and license plate of the vehicle body.

  In addition, when the vehicle C existing in the tunnel # 1 captures a fire image and transmits it to the road traffic control device 1, particularly when the image captured by the tunnel camera 81 (FIG. 3) is unclear due to smoke or the like. It can be used as useful information.

  The program executed by the road traffic control device 1 and the vehicle control device 2 of the present embodiment is a file in an installable format or an executable format, such as a CD (Compact Disc) -ROM (Read Only Memory), a flexible disc. (FD), CD-R (Recordable), DVD (Digital Versatile Disk) and the like can be provided by being recorded on a recording medium readable by a computer device. Moreover, you may make it provide or distribute the program run with the road traffic control apparatus 1 and the vehicle control apparatus 2 of this embodiment via networks, such as the internet.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.

  For example, in order to specify the position of each vehicle C in the tunnel # 1, information of an image captured by the in-tunnel camera 81 may be used.

  Further, when displaying an evacuation exit (not shown) on the information board 82 (FIG. 3) in the tunnel # 1, for example, the information board 82 (not shown in FIG. 3) in the vehicle crowded area A2 (FIG. 3) is the most. A large evacuation exit may be displayed nearby, and a different evacuation exit may be displayed on the information board 82 in the non-crowded area A1. In this way, efficient and safer evacuation can be realized.

  Further, the correspondence control is not limited to the unlock control and the automatic operation control, and may be, for example, a hazard lamp lighting control.

  In addition, the communication method used in the tunnel # 1 by the mobile terminal possessed by the vehicle control device 2 or the vehicle C passenger may be Wi-Fi (registered trademark), Bluetooth (registered trademark), or the like.

  In the correspondence information shown in FIG. 4, “presence / absence of unlocking / automatic driving instruction” is divided into “presence / absence of unlocking instruction” and “presence / absence of automatic driving instruction”, and the presence / absence of these is independent. May be set separately.
