Description

  The present invention relates to a vehicle movement adjustment device that adjusts movement of a plurality of vehicles at the time of disaster.

  Conventionally, at the time of disaster, by using a vehicle, it is possible to evacuate from a dangerous place to a safe evacuation place quickly. However, when a plurality of vehicles go to the same evacuation site, the plurality of vehicles may concentrate on the evacuation site and the target route, and traffic congestion may occur. As a result, it may be difficult to properly evacuate from disasters.

  Therefore, in Patent Document 1, using a disaster information, a position information, and a map information, a branch path existing in a direction that is less susceptible to the disaster than the current location of the target vehicle is determined as a destination. The route from the current location of the target vehicle to the determined destination is determined as the target route using the traffic information and the map information, and the information of the determined destination and the target route to the on-vehicle device of the target vehicle The destination of each of a plurality of vehicles is selected from among a plurality of other branch roads which are transmitted and immediately before the target vehicle arrives at the current destination, and are in a direction less susceptible to the disaster than the current destination. A disaster path providing apparatus is disclosed that selects one branch to be dispersed and determines it as a new destination. According to such a disaster route providing apparatus, it is possible to provide a more appropriate target route at the time of evacuation from a disaster.

(Overview of Vehicle Movement Adjustment System)
First, an outline of a vehicle movement adjustment system for authenticating a user to which the present invention is applied will be described. The vehicle movement adjustment system is a system that adjusts movement of a plurality of vehicles at the time of disaster.

  FIG. 1 is a view for explaining the concept of a vehicle movement adjustment system 1 to which the present invention is applied.

  The vehicle movement adjustment system 1 includes a plurality of vehicle movement adjustment devices 10 respectively loaded on a plurality of vehicles (A to E in the example shown in FIG. 1).

  In the present embodiment, the vehicles A to E may be vehicles equipped with a known system for automatic driving, or a staff member who operates the vehicle movement adjustment system 1 or a user who has got on the vehicle (hereinafter also referred to as a “driver”). It may be a vehicle traveling by the operation of.).

  In the case of a disaster, for example, when the public network is down and communication via the Internet can not be performed, the vehicle movement adjustment system 1 directly communicates with a plurality of vehicle movement adjustment devices 10 in a range in which they can directly communicate with each other. This is a system that enables a plurality of vehicles to cooperate by performing (for example, ad hoc communication and the like). Here, “directly communicate with each other” does not necessarily mean one-to-one communication, and it is substantially effective that vehicles that can communicate with each other indirectly communicate with each other using a mesh network. May be the same as direct communication (same below). For example, when there are a vehicle A, a vehicle B, a vehicle C, and a vehicle D, direct communication is impossible between the vehicle A and the vehicle E, but it is possible to transmit information as A → B → C → D → E. As a result, information sharing by direct communication becomes possible. The position of the vehicle and the communication range at this time are shown in FIG. Here, the dotted circle in the figure indicates the communication distance, but as indicated by the dotted arrow in the figure, only the vehicle B is the vehicle A, the vehicle B is the vehicle A and the vehicle C, and the vehicle C is the vehicle B and Vehicle D, Vehicle D can communicate with Vehicle C and Vehicle E, Vehicle E can only communicate with Vehicle D, but all vehicles can communicate substantially "directly" via other vehicles in the network. Is possible. The vehicle of the present system can recognize a plurality of vehicles capable of such "direct communication" as a "group", which will be described later.

  In the vehicle movement adjustment system 1, a plurality of vehicle movement adjustment devices 10 present in a range in which they can directly communicate with each other have identification information (for example, information for identifying the vehicle movement adjustment device 10) in the other vehicle movement adjustment devices 10. Send.

  In the example shown in FIG. 1, in the vehicle movement adjustment system 1, a plurality of vehicles (for example, as shown in FIG. 1) exist in the range Aa where the vehicle movement adjustment devices 10 loaded on the vehicle A can directly communicate with each other. In the example shown, the timing of departure to the evacuation site B to D) is determined. Hereinafter, “timing to depart” or “timing to depart” refers to timing at which the moving object starts moving or resumes moving toward the evacuation site. The vehicle movement adjustment device 10 determines the timings of departure of a plurality of vehicles (A to D in the example shown in FIG. 1) to different timings. Specifically, in the example shown in FIG. 1, the vehicle movement adjustment device 10 sets the timing of the departure of the vehicle A five minutes after the timing of the departure of the vehicle A starting from the timing of the departure of the vehicle C 10 minutes after the timing of the departure of the vehicle B , 15 minutes after the timing of the departure of the vehicle D is determined.

  Moreover, although it may be any of the several vehicle movement adjustment apparatuses 10 which exist in the range which can communicate directly mutually, this timing is determined, for example, the priority set beforehand (for example, prescribed by identification information) The vehicle movement adjustment device 10 may be high.

  The vehicle movement adjustment device 10 loaded on the vehicle A transmits departure timing information related to the determined departure timing to another vehicle (B to D in the example shown in FIG. 1).

  The vehicle movement adjustment device 10 loaded on another vehicle (B to D in the example shown in FIG. 1) receives the departure timing information transmitted from the vehicle movement adjustment device 10 loaded on the vehicle A. A control means for controlling the movement of the vehicle in each vehicle and a person who operates each vehicle issue the vehicle to the evacuation site based on the departure timing information.

  Further, in the example shown in FIG. 1, although it is out of the range Aa in which direct communication with the vehicle movement adjustment device 10 loaded in the vehicle A is possible, the range Da in direct communication with the vehicle movement adjustment device 10 loaded in the vehicle D Inside, there is a vehicle E.

  In such a case, the vehicle movement adjustment device 10 loaded on the vehicle D determines the timing at which the vehicle E leaves the evacuation site. For example, the vehicle movement adjustment device 10 loaded on the vehicle D determines the timing of departure of the vehicle E in accordance with the departure timing information received from the vehicle movement adjustment device 10 loaded on the vehicle A. For example, the vehicle movement adjustment device 10 loaded on the vehicle D is the departure timing indicated by the departure timing information received from the vehicle movement adjustment device 10 loaded on the vehicle A (in the example shown in FIG. It determines at the timing (in the example shown in FIG. 1, 20 minutes after the departure of the vehicle C) different from the time after the minute.

  The vehicle movement adjustment device 10 loaded on the vehicle D transmits departure timing information related to the determined departure timing to another vehicle (E in the example illustrated in FIG. 1). The vehicle movement adjustment device 10 loaded on the other vehicle (E in the example shown in FIG. 1) receives the departure timing information transmitted from the vehicle movement adjustment device 10 loaded on the vehicle D. The control means for controlling the movement of the vehicle in the vehicle D and the person operating the vehicle D issue the vehicle to the evacuation site based on the departure timing information.

  According to such a vehicle movement adjustment device 10, it is possible to make the timings of departure to the evacuation places of a plurality of vehicles present in a range where direct communication with each other is possible mutually different. Therefore, it is possible to provide a vehicle movement adjustment device capable of distributing a plurality of vehicles heading for the evacuation site. In addition, by sending and receiving departure timing information regarding the timing of departure to the evacuation site directly between multiple vehicles, for example, even when the public network goes down and communication via the Internet is not possible, a plurality of heading to the evacuation site It is possible to disperse the vehicles of

(Functional configuration)
FIG. 2 is a diagram showing a functional configuration of the vehicle movement adjustment device 10 in the vehicle movement adjustment system 1 according to the embodiment of the present invention. The vehicle movement adjustment system 1 is configured by a plurality of vehicle movement adjustment devices 10 present in a range in which direct communication with each other is possible.

(Configuration of vehicle movement adjustment device 10)
The vehicle movement adjustment device 10 is provided in a vehicle, and includes disaster information acquisition means 11, transmission means 12, reception means 13, evacuation site determination means 14, movable distance calculation means 15, movement distance calculation means 16, and the like. A passenger number detecting means 17, a passenger available number calculating means 18, a transfer vehicle extraction means 19, a suggestion means 20, a departure timing determination means 21, a display means 22, and a time correction means 23.

  The disaster information acquisition unit 11 is information from the outside (for example, a server of a public organization such as the Japan Meteorological Agency) before the public network goes down (for example, immediately after the occurrence of a disaster etc.) Acquire certain disaster information. Moreover, the disaster information acquisition means 11 may have an imaging means (for example, a camera etc.) which image | photographs the circumference | surroundings of a vehicle, and may acquire the image information which imaged the condition etc. of disaster by this imaging means. The image information obtained by imaging the situation and the like of the disaster acquired by the disaster information acquiring unit 11 may be transmitted to the outside (a server such as an organization that performs disaster countermeasure, etc.) via, for example, a public network.

  When the disaster information acquisition unit 11 acquires disaster information, the transmission unit 12 transmits the disaster information to the vehicle movement adjustment device 10 of another vehicle existing in the direct communicable range (for example, the ad hoc communicable range). Do. Further, the disaster information to be transmitted here is not limited to the information acquired by the disaster information acquisition means 11, but may be an image captured by the vehicle or information converted from an image into characters. Thus, for example, since the disaster information can be provided to the vehicle movement adjustment apparatus 10 that could not receive disaster information because the public network went down after the disaster occurred, disaster information is transmitted even when the public network goes down. It is possible to

  In addition, the transmission means 12 includes information on possible number of people to be able to get on and off, departure timing information on the timing of departure, and information on the number of people to be transferred in addition to the identification information of the vehicle. It transmits directly to the vehicle movement adjustment device 10 of the vehicle.

  The receiving unit 13 directly receives disaster information from the vehicle movement adjustment device 10 of another vehicle that has acquired the disaster information. In addition, the reception means 13 may be the vehicle movement adjustment device 10 for other vehicles, including the available people number information indicating the possible number of passengers, which will be described later, the transferred people number information indicating the number of passengers to be transferred, etc. Receive directly from Moreover, the receiving means 13 directly receives departure timing information from the vehicle movement adjustment device 10 of another vehicle which has determined the timing of departure.

  As described above, the transmitting unit 12 and the receiving unit 13 can confirm to which “group” the own vehicle belongs by repeating communication with other vehicles. Here, the transmitting means 12 transmits an identifier of the vehicle at predetermined time intervals, and the receiving means 12 receives an identifier from another vehicle. As a result, a pair (pair) of vehicles capable of direct communication (having a history of communicating within a predetermined time) within the communication distance is grasped. The transmitting means 12 further detects, every predetermined time, that the reception result including the identifier from the other vehicle outside the communication distance is sent indirectly, and the receiving means 13 receives the other one outside the communication distance. It detects that the vehicle identifier has been received indirectly. As a plurality of vehicles repeat this, a group of whole images in the network are sequentially synthesized, and the whole image is indirectly shared by communicable vehicles. At this time, for each vehicle, a list or a position diagram (representing a pair) of identifiers of vehicles capable of direct communication, and a list or a location diagram of identifiers of vehicles capable of indirect communication (substantially direct communication) (Representing a group) is displayed as shown in FIG.

  The evacuation site determination means 14 determines an evacuation site based on the disaster information acquired by the disaster information acquisition means 11. The evacuation site determination means 14 may determine the nearest preset evacuation site from the current position as the evacuation site to which the vehicle is heading, or place an area which is a predetermined distance away from the place where the disaster occurred. You may decide. In addition, the evacuation site determination means 14 may determine that the evacuation sites are different among a group of communicable vehicles. For example, in the case where both the vehicle A and the vehicle B aim at the evacuation site 1 initially, it may be determined that the vehicle A moves to the evacuation site 2 when the possibility that the evacuation site 1 is congested is acquired. In addition, the freshness of the information held by each car may be different regarding evacuation site information (such as the number of people accommodated) and the passage unnecessary place information. Therefore, as for the evacuation site information and the impassable part information acquired by the vehicle, it is desirable to compare the time of the information and mutually update the possessed information.

  Further, when there are a plurality of candidates for evacuation places, the evacuation place determination means 14 may determine any evacuation places according to the type of disaster. For example, if the disaster is a tsunami, the evacuation site determination means 14 determines a site relatively away from the sea and a relatively high altitude as an evacuation site.

  The movable distance calculation means 15 calculates the movable distance which is the distance in which the vehicle can move. In detail, the movable distance calculation means 15 is previously set to the remaining amount of fuel of the vehicle (for example, the remaining amount of battery if the vehicle is an electric vehicle, the remaining amount of gasoline if a gasoline vehicle, etc.) Alternatively, the movable distance is calculated by multiplying the travel distance per unit fuel of the vehicle measured in advance. However, the calculation of the movable distance may not be the exact distance to the evacuation site, but may be the distance to a nearby location appropriate for the vehicle to drop the passenger. It is also possible to move on foot from the nearby location to the evacuation site.

  The movement distance calculation means 16 calculates the movement distance which is the distance from the current position of the vehicle to the evacuation site determined by the evacuation site determination means 14. The vehicle movement adjustment apparatus 10 uses GPS (Global Positioning System) of its own or a car navigation system of a vehicle or a vehicle to obtain positional information (for example, information indicated by latitude, longitude, etc.) between the current position and the evacuation site. The movement distance is calculated based on the acquired position information.

  The passenger number detection means 17 detects the number of passengers, which is the number of passengers getting on the vehicle. The passenger number detecting means 17 has a sensor for detecting the number of passengers, such as a human sensor or a weight sensor, and detects the number of passengers getting on the vehicle by this sensor.

  The possible number of people calculation means 18 subtracts the number of people detected by the number of people detection means 17 from the maximum number of people (maximum possible number of people) of the vehicle set in advance, and determines how many more people can get on the vehicle Calculate the number of possible passengers shown (the number of extra passengers). In addition, the possible passenger number calculation means 18 directly receives, from the vehicle movement adjustment device 10 of another vehicle, the transfer person number information indicating the number of the passengers to be transferred, together with the identification information of the other vehicles. In this case, the maximum number of passengers of the vehicle set in advance is reduced by adding the number of people indicated by the transfer number information received by the reception means 13 to the number of people detected by the number of people detection means 17 Calculate

  The transmitting means 12 directly transmits the boardable person number information indicating the possible boarding number calculated by the possible boarding number calculating means 18 to the vehicle movement adjustment device 10 of the other vehicle together with the identification information of the vehicle. Further, the receiving means 13 directly receives the boardable person number information from the vehicle movement adjustment device 10 of the other vehicle together with the identification information of the other vehicle.

  The transferable vehicle extraction unit 19 is configured such that the movable distance calculated by the movable distance calculation unit 15 is equal to or less than the movement distance calculated by the movement distance calculation unit 16 or the number of passengers of the own vehicle detected by the passenger number detection unit 17 If the number of passengers is not the maximum number of passengers, the driver extracts other vehicles that can be transferred to the vehicle. In detail, the transfer vehicle extraction means 19 includes the boardable person number information transmitted from the vehicle movement adjustment device 10 of the other vehicle received by the reception means 13 and the number of passengers detected by the boarding number detection means 17. Based on that, the other vehicle that the passenger can change is extracted.

  The transmission means 12 moves the vehicle of the vehicle which the transfer vehicle extraction means 19 has extracted, together with the identification information of the relevant vehicle, transfer person number information indicating the number of passengers of the transfer person (the number of the passengers detected by the number of people detector 17). Transmit directly to the coordinator 10. Also, the receiving means 13 directly receives the transfer person number information from the vehicle movement adjustment device 10 of the other vehicle together with the identification information of the other vehicle.

  The suggestion means 20 includes, for example, a display means constituted by a display or the like, a speech means constituted by a speaker or the like, etc., and by these means, it is suggested to the passenger to change to another vehicle. . Here, when the movable distance calculated by the movable distance calculation unit 15 is equal to or less than the movement distance calculated by the movement distance calculation unit 16, the suggestion unit 20 can move the vehicle to the evacuation site. When the distance is exceeded, it is suggested that the passenger switches to another vehicle (the vehicle extracted by the transfer vehicle extraction means 19). In addition, the suggestion means 20 suggests that the passenger of another vehicle is to switch to the vehicle if the number of passengers of the vehicle detected by the number of people detection device 17 is not the maximum number of passengers.

  That is, the suggestion means 20 is based on the movable distance of the vehicle and the movement distance to the evacuation site (taking into consideration the moving distance), and / or on the basis of the number of passengers of the own vehicle and other vehicles Taking into consideration the number of passengers), extract the vehicles that can be transferred, and suggest the transfer to the passengers of the vehicles. That is, when the host vehicle can not move to the evacuation site due to lack of fuel, etc., other vehicles heading to the same evacuation site that can be transferred are extracted to suggest transfer to the rider of the host vehicle. If the number of possible passengers of the host vehicle is large, another vehicle which can be switched to the host vehicle is extracted to suggest that the passenger of the vehicle should switch. Also, when suggesting a transfer, move the car to the vicinity of the transfer candidate car. By suggesting this kind of transfer, it is possible to reduce the number of vehicles heading for the evacuation site as much as possible, and to reduce the possibility of congestion.

  Further, the suggestion unit 20 may compare the number of passengers in a vehicle with the number of passengers in another vehicle to determine which vehicle is more efficient to switch to which vehicle. For example, when there are two vehicles for "five for five" and "three for five", it is better for two to move, but it is better for three to change (especially, In the case of a single road, a road with one lane, etc., it may be determined that the vehicle on which two people ride is ahead. In addition, the suggestion unit 20 may obtain information on a passenger and determine a vehicle that suggests a change of passenger. For example, if it is exchanged that a person who is difficult to transfer, such as a person with a legged person, is on board, it may be possible that the person does not reach the transfer suggestion.

  Further, in this case, the suggestion means 20 transmits the position information of a replenishment location such as a gas station or a charging station capable of refilling the nearest fuel to the control means for controlling the movement of the vehicle after the passenger gets off. Good. This allows the vehicle to move to the nearest supply location.

  Furthermore, in this case, the suggestion unit 20 may transmit, to the control unit that controls the movement of the vehicle, position information such as a road shoulder that does not interfere with the traveling of another vehicle after the passenger gets off. This makes it possible to move a vehicle that can not move to the evacuation site to a road shoulder or the like, thereby preventing a vehicle that can not be used to evacuate from obstructing the traveling of the vehicle that can be used to evacuate.

  The departure timing determination means 21 determines the timing at which a plurality of vehicles present in a range in which they can directly communicate with each other depart for the evacuation site. The departure timing determination means 21 determines the timings of departure of a plurality of vehicles to be different from each other. The departure timing determination means 21 determines the timing of departure of another vehicle that has received the available passenger number information received by the reception means 13. For example, the departure timing determination means 21 may issue departure times at predetermined intervals (for example, five minutes in the example shown in FIG. 1) in order from vehicles (vehicles with a large number of passengers) having the smallest possible number of passengers indicated by the available people information. At the delayed timing, the timing at which each vehicle starts is determined. Alternatively, a time obtained by adding a predetermined time to the received departure timing may be determined as the departure timing. Alternatively, the departure timing may be determined based on the movement distance to the evacuation site.

  The transmission means 12 of the vehicle movement adjustment device 10 having determined the timing of departure determines the departure timing information (information indicating the time for departure to the evacuation site) regarding the timing determined by the departure timing determination means 21 at the timing of the departure timing information. It directly transmits to the vehicle movement adjustment device 10 of the vehicle to be released. The receiving unit 13 of the vehicle movement adjustment device 10 of the vehicle directly receives the departure timing information. The control means for controlling the movement of the vehicle in the vehicle and the person operating the vehicle cause the vehicle to depart to the evacuation site based on the departure timing information. Note that the departure timing determined once may be changed and rescheduled. For example, every time direct communication (such as ad hoc communication) between vehicles is established and information is exchanged, the information held by each vehicle may change. In that case, the departure timing and the destination are changed mutually. It is also good.

  The display means 22 displays the timing of the departure determined by the departure timing determination means 21 in the car, and displays the information suggested by the suggestion means 20 in the car. The reason for displaying the timing of departure is because it is not clear when the passenger will depart.

  The time correction means 23 receives time information from a standard radio wave (standard frequency radio wave) or GPS satellites when disaster information is received or the like, and automatically corrects an error of the on-vehicle clock. Alternatively, the times of the on-board clocks of a plurality of vehicles may be exchanged with each other, and the time may be adjusted to the on-board clock as a reference. In order to determine the departure timing, it is necessary for the clocks of each vehicle to be aligned, and at least for vehicles heading for the same evacuation site.

  The functional configuration of the above-described present system described above is merely an example, and one functional block (database and functional processing unit) may be divided or a plurality of functional blocks may be collectively configured as one functional block. It is also good. Each function processing unit is a computer program (for example, a computer program) stored in a storage device such as a ROM (Read Only Memory), a flash memory, an SSD (Solid State Drive), or a hard disk. , Core software etc.), and realized by a computer program executed by the CPU. That is, each function processing unit reads and writes necessary data such as a table from a database (DB) stored in a storage device or a storage area on a memory, and in some cases, the computer program It is realized by controlling hardware (for example, an input / output device, a display device, a communication interface device). Further, the database (DB) in the embodiment of the present invention may be a commercial database, but also means a mere collection of tables and files, and the internal structure of the database itself is not limited.

(Processing flow)
FIG. 4 is a diagram showing a transfer suggestion (when it is not possible to move) process flow executed by the vehicle movement adjustment device 10 according to the embodiment of the present invention. In the following process flow diagram (flow chart), the processing order of each step may be interchanged as long as the relationship between the input and the output of each step is not impaired.

  In step S1, the disaster information acquisition means 11 acquires disaster information which is information relating to a disaster from, for example, the vehicle movement adjustment device 10 provided on the outside or another vehicle via a public network.

  In step S2, the evacuation site determination means 14 determines an evacuation site based on the disaster information acquired by the disaster information acquisition means 11 in step S1.

  In step S3, the movable distance calculation means 15 calculates the movable distance which is the distance in which the vehicle can move.

  In step S4, the movement distance calculation means 16 calculates the movement distance which is the distance from the current position of the vehicle to the evacuation site determined by the evacuation site determination means 14 in step S2.

  In step S5, the vehicle movement adjustment device 10 determines whether the movable distance calculated by the movable distance calculation means 15 in step S3 is equal to or less than the movement distance calculated by the movement distance calculation means 16 in step S4. If it is determined that the distance is equal to or less than, the process proceeds to step S6. If it is not determined that the distance is equal to or less than the movement distance, the process ends.

  In step S6, the receiving means 13 receives, from other vehicles, the boardable number information indicating the possible number of boardings of the vehicle together with the identification information of the vehicle.

  In step S7, the boarding number detection unit 17 detects the number of boarding persons, which is the number of boarding persons boarding the vehicle.

  In step S8, the transfer vehicle extraction means 19 changes the passenger based on the possible number of people information and identification information received by the reception means 13 in step S6 and the number of people detected by the number of people detection means 17 in step S7. Extract other vehicles that can be. Specifically, for example, if the number of passengers is two, the transfer vehicle extraction unit 19 extracts vehicles having two or more people who can ride. The transmission means 12 moves the vehicle of the vehicle which the transfer vehicle extraction means 19 has extracted, together with the identification information of the relevant vehicle, transfer person number information indicating the number of passengers of the transfer person (the number of the passengers detected by the number of people detector 17). Transmit directly to the coordinator 10.

  In step S9, the suggestion means 20 suggests the passenger to switch to the vehicle extracted by the transfer vehicle extraction means 19 in step S8 by the display means or the like.

  FIG. 5 is a diagram showing a process flow of transfer suggestion (when the maximum number of passengers is not reached) executed by the vehicle movement adjustment device 10 according to the embodiment of the present invention.

  In step S11, the disaster information acquisition unit 11 acquires, for example, disaster information that is information related to a disaster from the vehicle movement adjustment device 10 provided on the outside or another vehicle via a public network.

  In step S12, the boarding number detection unit 17 detects the number of boarding persons, which is the number of boarding persons boarding the vehicle.

  In step S13, the possible boarding number calculating means 18 subtracts the number of boarding persons detected by the boarding number detecting means 17 in step S12 from the maximum number of boarding persons of the vehicle set in advance, and is the number of persons able to board the vehicle. Calculate the possible number of passengers.

  In step S14, the transmitting means 12 directly transmits the boardable people number information indicating the possible number of boarders calculated by the possible boarding number calculating means 18 in step S13 to the vehicle movement adjustment device 10 of another vehicle together with the identification information of the vehicle. Send.

  In step S15, the vehicle movement adjustment device 10 determines whether the number of passengers detected by the number-of-passengers detection unit 17 in step S12 is smaller than the maximum number of passengers of the vehicle set in advance. If it is determined that the number of passengers is less than the maximum number of passengers (if the maximum number of people is on board), the process ends.

  In step S16, the vehicle movement adjustment device 10 determines whether the reception means 13 directly receives the transfer person number information from the vehicle movement adjustment device 10 of the other vehicle together with the identification information of the other vehicle. If it is determined that the transfer number information is received, the process proceeds to step S16A. If it is determined that the transfer number information is not received, the process proceeds to step S17. When it is determined that the boarding possible number of people calculating means 18 receives the boarding number information, in the process of step S16A, the boarding possible number of people is subtracted from the number of persons indicated by the boarding number information received by the receiving means 13 Update the possible number of people. Thereafter, the process proceeds to step S14. Specifically, for example, if the maximum number of passengers of the vehicle set in advance is four and the number of passengers detected in step S12 is two, the number of possible passengers at that time is one. However, when there is one person indicated by the transfer person number information received by the receiving means 13, the transferable number of people is subtracted to update the number of possible passengers to one.

  In step S17, the receiving unit 13 receives, from other vehicles, the boardable number information indicating the possible number of boardings of the vehicle together with the identification information of the vehicle.

  In step S18, the transfer vehicle extraction means 19 receives the possible passenger number information and identification information received by the reception means 13 in step S17, the number of passengers detected by the number of people detection means 17 in step S13, and the reception means 13 in step S16. Based on the information on the number of persons transferred, the driver extracts other vehicles that the passenger can change.

  In step S19, the suggestion means 20 suggests the passenger to switch to the vehicle extracted by the transfer vehicle extraction means 19 in step S18 by the display means or the like.

  FIG. 6 is a diagram showing a vehicle movement adjustment process flow executed by the vehicle movement adjustment device 10 according to the embodiment of the present invention.

  In step S21, the disaster information acquisition unit 11 acquires, for example, disaster information that is information related to a disaster from the vehicle movement adjustment device 10 provided on the outside or another vehicle via a public network.

  In step S22, the receiving unit 13 receives, from the other vehicles, the boardable number information indicating the number of boardable persons of the vehicle together with the identification information of the vehicle.

  In step S23, the departure timing determination means 21 determines the timing at which a plurality of vehicles present in the range in which they can directly communicate with each other depart for the evacuation site. The departure timing determination means 21 determines the timing of departure of each vehicle at a timing at which the departure time is delayed at a predetermined interval, in order from the vehicle with the smallest possible number of passengers indicated by the available people information.

  In step S24, the transmission means 12 transmits the departure timing information on the timing determined by the departure timing determination means 21 in step S23, together with the identification information of the vehicle to be launched at the timing of the departure timing information, the vehicle movement adjustment device 10 for the vehicle. Send directly to The receiving means 13 of the vehicle movement adjustment device 10 of the vehicle directly receives the departure timing information, and the control means for controlling the movement of the vehicle and the person who operates the vehicle evacuate the vehicle based on the departure timing information. Drive to the place.

  For example, in the example shown in FIG. 1, the number of possible passengers of the vehicle A is one, the number of possible carriages of the vehicle B is two, the number of possible carriages of the vehicle C is zero, and the carriage of the vehicle D is possible. This is an example in which the number of persons is three and the number of accessible persons of the vehicle E is four. In this case, for example, the departure timing determination means 21 of the vehicle movement adjustment device 10 of the vehicle A sets the vehicle B in 5 minutes after the timing of departure of the vehicle A starting from the timing of departure of the vehicle C in the processing of step S23. 10 minutes after the timing of departure of the vehicle, and 15 minutes after the timing of departure of the vehicle D. Further, the departure timing determination means 21 of the vehicle movement adjustment device 10 of the vehicle D indicates the departure timing of the vehicle E as indicated by the departure timing information transmitted from the vehicle movement adjustment device 10 of the vehicle A by the process of step S24. The timing is determined after 20 minutes which is different from the timing after 15 minutes.

(Effect of the embodiment)
According to the present embodiment, it is possible to make the timings of departure of vehicles of a plurality of vehicles present in a range in which they can directly communicate with each other different from each other. Therefore, it is possible to provide a vehicle movement adjustment device, a vehicle movement adjustment method, and a program capable of distributing a plurality of vehicles heading for an evacuation site. In addition, by sending and receiving departure timing information regarding the timing of departure to the evacuation site directly between multiple vehicles, for example, even when the public network goes down and communication via the Internet is not possible, a plurality of heading to the evacuation site It is possible to disperse the vehicles of

  Also, if the movable distance of the vehicle is equal to or less than the moving distance from the current position to the evacuation site, it suggests the passenger to switch to another vehicle, so the fuel is on the way to the evacuation site. It is possible to avoid the situation where you can not stop at the evacuation site because you are stuck in the end. Therefore, it becomes possible to make a passenger arrive at a refuge place reliably.

  In addition, when the number of passengers of a certain vehicle is not the maximum number of passengers, another vehicle that allows the passenger to transfer to that vehicle is extracted, suggesting a transfer to another vehicle, so the vehicle is transferred by transfer. It is possible to use more efficiently and carry more people to evacuation sites.

  Further, by providing the time correction means, it is possible to eliminate the occurrence of inconsistencies in the determination of the departure timing in each vehicle.

  Although the present invention has been described above using the embodiment, it goes without saying that the technical scope of the present invention is not limited to the scope described in the above embodiment. It is apparent to those skilled in the art that various changes or modifications can be added to the above embodiment. It is also apparent from the scope of the claims that the embodiments added with such alterations or improvements can be included in the technical scope of the present invention.
