JP 2007-206803 A

  During an evacuation simulation, you may want to check the route a pedestrian has taken. Therefore, we want to display the movement route on the walking area of the pedestrian.

  On the other hand, in the evacuation simulation, a pedestrian may be moving but not walking. For example, there is a warp area that warps the evacuating pedestrian to another position, which is used when the pedestrian is moved to the floor and moved to another floor drawing.

  In the case of a complicated map / design drawing, it is difficult to know from which warp area the pedestrian has moved to which warp area simply by displaying the movement trajectory on the walking area.

  In addition, it is desired to display a trajectory indicating from which warp area the pedestrian has moved to which warp area, but this trajectory is different from the movement trajectory in which the pedestrian has actually walked and moved. For this reason, for example, a simple diagram with a small warp area may not be displayed.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a mechanism that can easily display a position related to evacuation of an evacuee according to information on a history of positions.

  According to the present invention, first deciding means for deciding the next position of the refugee according to the information of the refugee to perform an evacuation simulation of the refugee, and the refugee has reached a predetermined point An information processing apparatus comprising: a second determination unit that determines a next position of the evacuee according to information on the predetermined point, wherein the first determination unit and the second determination unit From the position before the next position is determined by the first determining means to the next position determined by the first determining means, which is specified based on the history of the positions of the evacuees determined by Control means for controlling the display of the first section which is a section of the first section.

  The information processing apparatus 100 in this embodiment is a PC, and the CAD software 110 is CAD (Computer-Aided Design) application software installed in the information processing apparatus. The evacuation simulation software 120 is software that performs an evacuation simulation using CAD graphics (objects) and stores and manages the result, which functions as a plug-in of CAD application software.

  The evacuation simulation software 120 includes a simulation engine. Using the simulation engine, the evacuation simulation software 120 uses a pedestrian icon (walking) placed in a walking area (an object indicating an area where the pedestrian icon is allowed to walk) on the map created by the CAD software 110. Simulation processing for evacuating a person's object) to an evacuation place (evacuation destination) on the map.

  More specifically, the evacuation simulation software 120 advances the simulation time from the start of the simulation at regular intervals, and performs a simulation process for moving the pedestrian icon toward the evacuation site as time passes. .

  The evacuation simulation software 120 can perform an evacuation simulation assuming various disasters. For example, the evacuation simulation software 120 can perform an evacuation simulation assuming the occurrence of water disasters such as tsunami, flood, river flooding, fire, earth and sand disasters. The above is the description of FIG.

  Next, an example of the hardware configuration of the information processing apparatus 100 in the embodiment of the present invention will be described with reference to FIG.

  The information processing apparatus 100 includes a CPU 201, a ROM 202, a RAM 203, an input controller 205, a video controller 206, a memory controller 207, and a communication I / F controller 208. The CPU 201, ROM 202, RAM 203, input controller 205, video controller 206, memory controller 207, and communication I / F controller 208 are connected to each other via a system bus 204.

  The CPU 201 is a central processing unit that controls each device and controller connected via the system bus 204. The ROM 202 is a storage device that stores various programs such as BIOS (Basic Input / Output System) that is a control program of the CPU 201, various data, and the like.

  A RAM 203 is a storage device that functions as a main memory, work area, and the like of the CPU 201. The CPU 201 implements various operations by loading a program or the like necessary for executing the processing from the ROM 202 or the external memory 211 to the RAM 203 and executing the loaded program.

  The input controller 205 is a controller that controls input from the input device 209. The input device 209 is an input device such as a pointing device such as a keyboard (KB) or a mouse. The video controller 206 is a controller that controls display on the display device 210. The display device 210 is a display device such as a CRT display (CRT). The display device 210 may be other display devices such as a liquid crystal display as well as a CRT.

  The memory controller 207 is a controller that controls access to the external memory 211. The external memory 211 is a storage device such as a hard disk (HD) or a flexible disk (FD) that stores an operating system program (hereinafter referred to as OS), various setting information, and the like. The external memory 211 stores a boot program, various application programs, font data, user files, editing files, various data, and the like. The memory controller 207 can also control access to the external memory 211 such as a flash memory type memory card connected to the PCMCIA card slot via an adapter.

  The communication I / F controller 208 is a controller used for connection / communication with an external device via a network such as a LAN or the Internet, and executes communication processing via the network. The communication I / F controller 208 can communicate with an external device using TCP / IP, for example.

  The CPU 201 enables display on the display device 210 by executing outline font rasterization processing on a display information area in the RAM 203, for example. Further, the CPU 201 can accept a user instruction via a mouse cursor or the like on the display device 210.

  Although various programs for realizing the processing of the present embodiment are stored in the external memory 211, they may be stored in the ROM 202. In addition, the definition file and various information tables used when executing the program are stored in the external memory 211, but may be stored in the ROM 202.

  The display device 210 is an example of an output unit that displays and outputs an object generated by the CAD software 110 in response to an instruction from the evacuation simulation software 120 (for example, a new road object that connects a building and a road). The above is the description of FIG.

  When the CPU 201 executes a process based on a program stored in the ROM 202 or the external memory 211, the function of the information processing apparatus 100 described later with reference to FIG.

  FIG. 3 is a diagram illustrating an example of a functional configuration of the information processing apparatus 100. The information processing apparatus 100 includes CAD software 110 (CAD drawing function unit) and evacuation simulation software 120 (evacuation simulation function unit).

  The object generation unit 311 generates an object that is a CAD figure in response to a user operation on the CAD software 110 or an instruction from the evacuation simulation software 120.

  The object storage management unit 312 is a functional unit that stores and manages a generated object in an external memory. An example of the object is shown in the object information 400 of FIG.

  Each object has information of an object ID 401 that is object identification information, and vertex coordinates 402 (X and Y coordinates on a CAD file (on the drawing)) of the object. The shape connecting the vertices in turn is the shape of the object.

  Further, as shown in the attribute 403, an attribute indicating what the object is is stored in association with each other. Attributes include, for example, roads, buildings, obstacles, walking areas, pedestrians, walking speeds, and the like.

  The area indicated by the object to which the attribute of the walking area is given indicates that the pedestrian (evacuee) can walk in the evacuation simulation. An object (building object) to which a building attribute is assigned indicates a building. An object to which a road attribute is assigned (a road object) indicates a road.

  For example, reference numeral 601 in FIG. 6 is an object indicating one floor of one building, and has an attribute of a walking area. Reference numerals 603 and 606 denote objects having a staircase attribute, and are given a walking area attribute. Reference numeral 606 denotes an object created for confirming the state of movement of the pedestrian on the stairs between the floors.

  An object to which an attribute of an obstacle is given (obstacle object) indicates an obstacle that defines an area where a pedestrian cannot pass. When objects in the walking area are in contact with each other or overlapping, the pedestrian can freely move between the objects in contact with or overlapping each other.

  If the obstacle object and the pedestrian icon overlap, the pedestrian icon is made immovable and fixed at the position where the obstacle object overlaps. As an example of the obstacle object, there is a tsunami object whose shape is determined from data of a tsunami inundation area. Also, debris that falls due to the collapse of a building is an obstacle object.

  Attribute 403 = Pedestrian object is a pedestrian icon. In the present embodiment, it is assumed that the pedestrian icon is already arranged on the drawing (initial position is registered) as indicated by 602 in FIG.

  Here, the drawing is a CAD file that can be developed by the CAD software 110, and is a file in which figures (objects) are arranged. The evacuation simulation software 120 executes an evacuation simulation using, for example, a drawing developed by the CAD software 110.

  From the vertex coordinates of the pedestrian icon, the center position of the pedestrian icon can be specified. The center position is the initial position of the pedestrian icon before evacuation.

  The speed (m / sec) of the pedestrian icon is a moving speed at which each pedestrian icon moves toward the destination in the evacuation simulation.

  An object having a warp ID in the attribute 403 is an object indicating the warp area (warp area itself). In the present embodiment, two objects having the same warp ID are created for each warp ID, and objects having the same warp ID are created and stored as objects of the same shape.

  The evacuation simulation software 120 warps another warp area having the same warp ID as the warp area when a pedestrian icon overlaps an object in one warp area, that is, when the pedestrian reaches the warp area. Identified as the previous warp area. Then, the same position in the warp area of the warp destination as the position in the warp area where the pedestrian icon has reached is determined as the next position (warp destination position) of the pedestrian icon. An example of an object in the warp area is shown at 604, 607, etc. in FIG.

  In addition, it is assumed that the evacuation destination is already generated and arranged on the drawing as an object having the attribute of the evacuation destination. An example of the destination object is shown in 605, 608, 609, etc. in FIG.

  The attribute 403 includes color setting and transparency setting for each object. The above is the description of the object information 400.

  Returning to the description of FIG. The object display setting unit 313 stores, updates, and changes settings related to object display. For example, part or all of the object instructed from the evacuation simulation software is hidden or the color setting is changed.

  The object display unit 314 arranges and outputs an object on the drawing according to the color and transparency set by the object display setting unit 313, and displays the object on the display screen.

  The simulation execution unit 321 is a processing unit that performs a simulation of evacuating a pedestrian icon for evacuation purposes. For example, the simulation is performed by determining the position of the next movement destination of the pedestrian from the position and speed of the pedestrian every predetermined time (for example, every 0.1 second from the start of the simulation).

  The simulation is performed from the start of simulation until a predetermined time later. It is assumed that the information on the predetermined time is stored in advance in an external memory.

  When a pedestrian enters the warp area, the other warp area that is paired with the warp area is specified, and a predetermined position on the other warp area is moved to the next destination of the pedestrian icon. Determine the position. And the history of the position of these pedestrians is outputted as a simulation result.

  The position history storage unit 322 stores the pedestrian position history information output from the simulation execution unit 321 from the simulation start to the end. An example of position history information is shown in route data 410 in FIG.

  The route data 410 is newly generated every time the evacuation simulation is executed and stored in the external memory.

  The date and time 411 indicates the data recording date and time. Time 412 is the elapsed time from the start of the simulation. The position 414 is the position (X and Y coordinates on the drawing) of the pedestrian icon with the icon ID 413 at the date 411 and the time 412.

  For example, the normal section specifying unit 323 specifies the walking section in which the pedestrian icon has moved according to the attribute information of the pedestrian icon itself. For example, when the pedestrian icon has entered the warp area and moved to another warp area position, the warp section specifying unit 324 specifies the section of the position before and after the movement as the warp section.

  Specifically, when a distance between two consecutive positions of one pedestrian is a predetermined distance (eg, 1.5 m) or more, a section between these two positions is specified as a warp section. . When the distance is less than 1.5 m, the section between these two positions is specified as a normal section.

  Here, a distance of 1.5 m is given as an example of the predetermined distance. Drawings with different floors are often drawn at regular distance intervals (for example, distance intervals of 1.5 m or more), so when the straight line distance of one section is 1.5 m or more, the floor is used between warp areas. It is because it is thought that it is moving. In addition, from the setting of the pedestrian movement speed in the evacuation simulation of this embodiment, it is difficult to think that the pedestrian icon walks 1.5 m in 0.1 seconds, so 1.5 m is set as a reference value. doing.

  The value of the predetermined distance can be arbitrarily set / changed on a setting screen (not shown) of the evacuation simulation software 120, and the set / changed value is stored in the external memory 211.

  The object display control unit 325 is a control unit that instructs the CAD software 110 to create and display an object in a normal section and an object in a warp section and control display of the object.

  For example, the CAD software is instructed to display only the normal section, or instructed to identify and display the object in the normal section and the object in the warp section. The above is the description of FIG.

  Next, with reference to FIG. 5, the flow of simulation execution in the embodiment of the present invention will be described.

  In step S <b> 501, the CAD software 110 is activated in response to an operation by the user via the input device 209.

  Further, the CAD software 110 reads drawing data from the external memory 211 or the like in response to a user operation via the input device 209, and develops and stores information on the read drawing data on the RAM 203. For example, it is assumed that drawing data that is a set of objects as shown in the object information 400 is read.

  Then, the CAD software 110 displays an object (a drawing including the object) corresponding to the drawing data stored on the RAM 203 on the display screen of the CAD software 110 displayed on the display device 210.

  For example, as shown at 600 in FIG. 6, the drawing is displayed on a window displayed by the CAD software. In 600 of FIG. 6, the CAD software 110 reads the drawing information (for example, the object information 400) into the RAM 203 and arranges it on the screen of the CAD software 110 displayed on the display device 210 according to the value of the vertex coordinate 402. doing.

  In step S <b> 502, the CAD software 110 activates the evacuation simulation software 120 in response to a user operation via the input device 209. When the evacuation simulation software 120 has already been activated, the CAD software 110 displays the setting screen of the evacuation simulation software 120 with respect to the activated evacuation simulation software 120 in response to a user operation via the input device 209. Instruct the display.

  In step S503, the evacuation simulation software 120 is activated by the activation instruction from the CAD software 110 in step S503, and displays the setting screen of the evacuation simulation software 120 on the display screen displayed by the CAD software 110.

  Specifically, the CAD software 110 activates the evacuation simulation software 120 by selecting “evacuation simulation” in the button list 610 displayed by the CAD software 110 when the tool tab of the CAD software 110 is pressed. Put out. The evacuation simulation software 120 that has received the activation instruction displays a setting screen 620 (illustrated in FIG. 6) in step S503.

  In step S504, the evacuation simulation software 120 receives an evacuation simulation execution instruction (start instruction) based on a screen displayed on the display device 210 or a user operation via the input device 209.

  For example, the evacuation simulation software 120 receives an instruction to execute an evacuation simulation by receiving selection of an “execution” button on the setting screen 620 based on a user operation via the input device 209.

  In step S505, the evacuation simulation software 120 acquires information on the pedestrian icons arranged on the drawing opened by the CAD software 110. For example, the CAD software 110 is requested for a list of icon IDs of pedestrian icons included in the drawing (object information 400) being developed.

  The CAD software 110 that has received the request acquires the ID list of the pedestrian icons in the drawing being developed from the memory and transmits it to the evacuation simulation software 120, which receives and acquires the evacuation simulation software 120.

  In step S505, the evacuation simulation software 120 applies the processing in steps S506 to S512 to all unfixed pedestrian icons (not overlapping obstacles) every 0.1 second.

  In step S506, the evacuation simulation software 120 acquires one pedestrian icon to which the process has not been applied. And it is determined whether the said pedestrian icon has overlapped with the obstruction object (for example, tsunami object).

  Specifically, by using the API of the CAD software 110, a list of obstacle objects is requested and acquired from the CAD software 110, and the obstacle object frame specified by the vertex coordinates 402 of the obstacle object is included in the frame. When the vertex coordinates 402 of the pedestrian icon being processed overlap, it is determined that the pedestrian icon overlaps the obstacle object.

  If it is determined that the pedestrian icon being processed overlaps an obstacle object, the pedestrian icon that overlaps the obstacle object is identified as a pedestrian (refugee) who has escaped late (failed to evacuate) Thereafter, the position of the pedestrian icon is fixed until the simulation is completed (step S512).

  Specifically, the position of the pedestrian icon when the pedestrian icon overlaps the obstacle object is recorded in the position 414 of the pedestrian icon for each time 412 in the route data 410 until the simulation is completed. Keep doing. That is, the position is continuously stored until the simulation is completed.

  If it is determined in step 507 that the pedestrian icon does not overlap the obstacle object, the process proceeds to step S508.

  In step S508, the evacuation simulation software determines whether the pedestrian icon being processed is located within the warp area. Specifically, using the API of the CAD software 110, a list of objects having warp IDs in the attributes 403 (objects of the warp area) is requested and acquired from the CAD software 110.

  When the vertex coordinate 402 of the pedestrian icon being processed overlaps the frame (in the warp region) of the object in the warp region identified from the vertex coordinate 402 of the object in the warp region, the pedestrian icon is displayed in the warp region. It is determined that it is located within.

  If the evacuation simulation software 120 determines that the pedestrian icon being processed is located within the warp area, the process proceeds to step S509. If it is determined that the pedestrian icon being processed is located outside the warp area, the process proceeds to step S510.

  Even if it is determined that the current position of the pedestrian is within the warp area, if the previous position is within the same warp area, for example, the warp has already been warped from another warp area. It is determined that a pedestrian is walking out of the area, and the process proceeds to step S510. Thereby, after the pedestrian enters the warp area, a wasteful process of warping to the other warp area every time the pedestrian moves to the next position can be omitted. Therefore, even when creating a moving route object, which will be described later, a clear moving locus object can be created and presented to the user without creating and displaying a useless moving locus that reciprocates in the same warp area.

  In step S509, the evacuation simulation software 120 identifies the object in the warp area where the pedestrian icon is located, and identifies another object having the same warp ID as the object in the warp area as an object in the warp destination warp area. .

  Objects in the warp area having the same warp ID are paired (paired) areas that are the movement source / destination of the pedestrian icon. Assume that the objects in the paired warp regions have the same shape.

  In step S511, the evacuation simulation software 120 determines the position in the warp area that is the warp destination, which is the same as the position in the warp area where the pedestrian icon is located, as the position of the next movement destination of the pedestrian icon. The position (X, Y) on the drawing of the movement destination is stored above.

  Specifically, when the route data 410 related to the currently executed evacuation simulation is not generated on the RAM, the route data 410 for the evacuation simulation is newly generated on the RAM, and 0 seconds after the start Insert the initial position of the pedestrian icon in the data. Then, a record of the pedestrian icon being processed is added to the data of the next time (for example, after 0.1 second) of the route data 410, and the position in the warp area of the warp destination is inserted into the position 414. Remember. If the route data 410 for the evacuation simulation already exists on the RAM, processing for adding the record to the route data 410 and storing the position is performed. In addition, according to the drawing of FIG. 6, since the warp area is created larger than the destination, the pedestrian icon moving toward the destination is warped area before reaching the destination of each floor. And warp to another warp area at the warp destination.

  On the other hand, in step S510, the evacuation simulation software 120 acquires information on the moving speed of the pedestrian icon being processed, and calculates the position of the pedestrian after a predetermined time.

  For example, a passing point to be passed to the evacuation destination is calculated, a straight line from the current position of the pedestrian icon to the calculated passing point is virtually created, and the speed of the pedestrian icon (eg, 1 m / second) ), The position X at the next time (after a predetermined time / example: after 0.1 second) when moving on the straight line toward the passing point is calculated as the position of the pedestrian.

  In step S511, the evacuation simulation software 120 determines the calculated next position as the next position of the pedestrian icon and stores it in the memory. For example, the record of the pedestrian icon is added to the data of the next time 412 of the route data 410 on the RAM, and the position X that is the next position is stored in the position 414.

  In addition, the calculation method of the next position of a pedestrian is not restricted to this. The calculation method of the next position differs depending on the calculation method of the simulation engine. However, in this embodiment, the next position of the pedestrian when the process is shifted from step S510 to S511 is calculated and determined based on the moving speed of the pedestrian himself acquired in step S510.

  Note that the processes in steps S506 to S512 for each pedestrian icon are performed in parallel as much as possible. The evacuation simulation software 120 applies the process from step S506 to S512 to all pedestrian icons, and the process proceeds to step S513.

  In step S513, the evacuation simulation software 120 determines whether the simulation end condition is satisfied. The simulation end condition is, for example, a condition such as whether or not a predetermined time (in this case, 300 seconds in the simulation) has elapsed since the simulation started.

  In the present embodiment, it is determined that the simulation end condition is satisfied when 300 seconds elapse after the simulation starts.

  Note that the simulation end condition is not limited to time. For example, it may be determined that all the pedestrian icons have reached the evacuation destination as an end condition, and it is determined that the end condition is satisfied when all the pedestrian icons have reached the evacuation destination.

  If the end condition is not satisfied, the process proceeds before step S505, and the pedestrian icon movement process (evacuation simulation process) is continued. If the end condition is satisfied, the process of FIG. 5 is ended and the evacuation simulation is completed. Then, the evacuation simulation software 120 stores the route data 410 stored on the RAM in the external memory 211 in association with an ID newly assigned for each evacuation simulation. The above is the description of FIG.

  Next, with reference to FIG. 7, the flow of a root object creation process in the embodiment of the present invention will be described.

  The route object is an object that indicates a movement trajectory of a pedestrian, and an object that indicates a history of a position for each pedestrian in the evacuation simulation.

  In step S701, the CAD software 110 receives a user operation. For example, a user operation is accepted on the screen 600 shown in FIG. 9 is the same screen as the screen 600 in FIG.

  In step S <b> 702, the CAD software 110 determines whether the received user operation is a command execution operation for plotting a movement trajectory.

  Specifically, when an operation for selecting a button for a walking trajectory plot command is received from the menu of the CAD software 110 indicated by reference numeral 610 in FIG. 9, it is determined that a command execution operation for plotting the moving trajectory has been performed.

  There are other operations that the CAD software 110 can accept. For example, an object selection operation. For example, by accepting a mouse click operation while the mouse cursor is over the object, the CAD software 110 accepts the object selection / deselection operation, and determines / stores the object selection state according to the operation.

  For example, for example, by accepting an operation of placing a mouse cursor on an arbitrary pedestrian icon and clicking, the selection of the clicked pedestrian is accepted, and the pedestrian icon is set in a selected state. The selected pedestrian icon is stored in a list of selected objects (not shown) stored in the memory, and manages the selected pedestrian object.

  In step S703, the CAD software 110 instructs the evacuation simulation software 120 to execute a command. In step S704, the evacuation simulation software 120 accepts a command execution instruction.

  In step S705, the evacuation simulation software 120 accepts the command execution instruction and displays a route creation target selection screen (not shown). On the selection screen, the route data stored when the simulation of FIG. 5 is completed is displayed in a list in parallel with the ID of the evacuation simulation. The evacuation simulation software 120 accepts a user operation for selecting route data for which a route object is to be created from the route data displayed in the list on the selection screen.

  Then, the selected route data is read out on the RAM, and using the selected route data, a route object creation process for the past position of the pedestrian icon is executed. In the description of this figure, it is assumed that the route data 410 is selected, read out and stored in the RAM.

  After receiving the selection of the route data 410, the evacuation simulation software 120 displays a dialog as shown by 900 in FIG. 9 on the display screen.

  In step S706, the evacuation simulation software 120 accepts a user operation on the dialog 900.

  In step S707, it is determined whether the operation accepted in step S706 is a root object creation execution operation. Specifically, when an operation for selecting an “OK” button 901 in the dialog is accepted, it is determined that an operation for executing the root object creation has been performed.

  If it is determined that a root object creation execution operation has been performed, the process proceeds to step S708. If the operation accepted in step S706 is not a root object creation execution operation, for example, if the operation is a “cancel” button selection operation, the process ends.

  Note that if the evacuation simulation software 120 determines that a route object creation execution operation has been performed in step S707, the evacuation simulation software 120 performs a pedestrian determination process and a storage process for a route object creation target.

  For example, the evacuation simulation software 120 determines whether the operation accepted in step S706 is an operation for creating a route object only for a pedestrian (pedestrian icon) currently selected on the CAD software 110 drawing, or for all pedestrians. Determine whether the target operation.

  Specifically, the check state of the “draw only selected person” check box 902 in the dialog 900 when the “OK” button 901 is pressed is confirmed. The evacuation simulation software 120 performs a process of checking / unchecking by accepting a click operation of the check box 902.

  The evacuation simulation software 120 creates a route object only for the currently selected pedestrian when the “OK” button 901 is pressed when the “draw only selected person” check box 902 is checked. It is determined that an object creation execution operation has been performed.

  When an operation for processing only the selected pedestrian is performed, the evacuation simulation software 120 inquires of the CAD software 110 whether there is a selected pedestrian. Specifically, the CAD software 110 is requested to search for the pedestrian selected on the CAD software 110, and information on the presence or absence of the selected pedestrian is acquired from the CAD software 110.

  If there is a selected pedestrian icon, the CAD software transmits a list of object IDs of the selected pedestrian icon to the evacuation simulation software 120 as information indicating that the selected pedestrian is present. If there is no pedestrian icon selected, an empty object ID list is transmitted to the evacuation simulation software 120 as information indicating that no pedestrian is selected.

  The evacuation simulation software 120 refers to the information on the presence or absence of a pedestrian acquired from the CAD software 110, and determines whether there is a selected pedestrian icon. When there is a selected pedestrian icon, the object ID list of the selected pedestrian icon is stored on the RAM as a list of pedestrians to be processed.

  If there is no pedestrian icon being selected, all pedestrians are processed. Specifically, a list of object IDs of all pedestrian icons included in the route data 410 is read and stored on the RAM as a list of pedestrians to be processed.

  In addition, when the “OK” button 901 is pressed in a state where the “draw only selected person” check box 902 is not checked, object creation execution is executed for all pedestrians as the root object creation targets. It is determined that an operation has been performed. Here, all pedestrians are all pedestrian icons included in the route data 410.

  When an operation for processing all pedestrians is performed, the evacuation simulation software 120 reads and stores the object ID list of all the pedestrian icons on the RAM as a list of pedestrians to be processed.

  In step S708, the evacuation simulation software 120 specifies the route data 410 on the RAM selected by the user. That is, route data for all times is acquired.

  The evacuation simulation software 120 repeats the following process for all pedestrian icons included in the route data 410.

  In step S709, the evacuation simulation software 120 acquires one object ID of a pedestrian icon to which the process of step S711 has not been applied (unprocessed) from the route data 410. If there is no unprocessed pedestrian icon, the process proceeds to step S716.

  In step S710, the evacuation simulation software 120 determines whether the acquired pedestrian object ID is an ID of a pedestrian icon that is a route object creation processing target.

  Note that the list of IDs of the pedestrians for which the route object is to be created is determined and stored in the above-described pedestrian determination process and storage process for the route object creation target. If the evacuation simulation software 120 is included in the case where the object ID of the pedestrian acquired in step S709 matches one of the object IDs in the list of pedestrians to be processed, the evacuation simulation software 120 It is determined that the pedestrian icon is a processing target pedestrian.

  If it is determined that it is a processing target pedestrian, the process proceeds to step S711. If it is determined that it is not a processing target, the processing of steps S710 to S715 is skipped for the corresponding pedestrian. It returns to step S709.

  In the following description of FIG. 7, it is assumed that only a pedestrian selected on the CAD software 110 is selected as a route object creation target and stored on the RAM.

  If the object ID of the pedestrian icon acquired in step S709 is the ID of the pedestrian targeted for route object creation processing, the evacuation simulation software 120 moves the process to step S711. Here, when the object ID of the pedestrian icon being selected on the CAD software 110 is determined, the process proceeds to step S711.

  In step S711, the evacuation simulation software 120 determines whether there is a group of objects of the acquired pedestrian icon, and if not, instructs the CAD software 110 to create an object group of the movement route of the pedestrian. To do.

  The group of pedestrian objects is a data format for managing all objects created from a certain pedestrian route data 410 as a group for each pedestrian, for example, shown at 830 in FIG. That is, it is a group concerning the movement route of a pedestrian.

  For example, the evacuation simulation software 120 moves the pedestrian icon based on the attribute set to the pedestrian icon itself or additional information (speed stored in the attribute 403 in FIG. 4). This group is a group of route objects indicating a section and route objects of a section where the evacuation simulation software has moved the pedestrian icon based on other factors that do not depend on the attribute or additional information of the pedestrian icon.

  The other factor here is, for example, that the pedestrian icon has reached the warp area. A section between the two warp areas when the pedestrian icon has reached a certain warp area and moved to another warp area is called a warp section.

  A warp area is an area on a drawing that is particularly necessary when performing an evacuation simulation on a two-dimensional drawing, and is used as a pair of a warp source area and a warp destination area. In the case of a two-dimensional drawing, for example, drawings of rooms on the first floor and the second floor are drawn and created separately.

  In order to move the pedestrian icon from the first floor to the second floor, from the second floor to the first floor, for example, a warp area is set on the stair object in the drawing of each floor, and the pedestrian icon that has reached the warp area is moved to the other floor. It is necessary to move to the floor plan where the warp area is located.

  This is an example of the case where the evacuation simulation software moves the pedestrian icon based on other factors that do not depend on the attribute or additional information of the pedestrian icon.

  Also, especially on drawings with many floors and many stairs, the pedestrian icon will indicate which warp to make it easier to see which stairs have moved from which warp area to which stairs. It can be clarified by displaying as a root object which warp area has been moved from the area (position change / update).

  Also, by grouping these moving route objects, a plurality of objects created from the movement history of one pedestrian can be selected and operated for each pedestrian at once on the CAD software 110. Will be able to.

An example of a group is shown in group information 830 (FIG. 8). The group ID 831 is an identification ID of a group of travel routes for each pedestrian. The evacuation simulation software 120 inserts the object ID of the pedestrian icon of the route object belonging to the group into the group ID 831, and instructs the CAD software 110 to create and store the group.
That is, the group ID 831 is an ID indicating which pedestrian group the object of each object ID 832 is.

  1732 is an ID of an object created from the route data of the corresponding pedestrian. As shown in FIG. 8, the group information 830 is created for each pedestrian and stored in an external memory.

  Reference numeral 833 denotes a set of coordinates of one section of the vertex constituting the object. In the case of the route object, the coordinates of the two vertices of the line object (or polygonal object) indicating the movement trajectory of the pedestrian specified from the history of the position of the pedestrian are inserted.

  Reference numeral 834 denotes an attribute of the vertex 1 section of the object. In the case of a root object, for example, an RGB value and transparency of the object color are inserted into 834.

  In step S719, the CAD software 110 accepts an instruction to create a group of pedestrian movement routes.

  In step S720, the CAD software 110 creates a group of pedestrian travel routes. For example, when an instruction to create a group of a pedestrian icon with object ID = U00001 is received, a group of a moving route of pedestrian U00001 in 830 of FIG. 8 is newly created, and the value of U00001 is inserted into 831. At this time, data 832 to 834 are empty.

  The evacuation simulation software 120 acquires the pedestrian all route data 410 determined as the processing target in step S710. And the process to step S712-S715 is performed with respect to all the route data 410 of the said pedestrian.

  In step S712, the evacuation simulation software 120 identifies and acquires the route of one section of the pedestrian. The route of one section is a set of two positions where recording time (time 412 or date and time 411) of one pedestrian is continuous.

  For example, it is a set of positions where the elapsed time 0 second and 0.1 second of U00001 referred to as 410 in FIG.

  In step S713, the evacuation simulation software 120 determines whether the route of one section acquired in step S712 is a warp section.

  Specifically, it is determined whether the straight line distance of the one section is a predetermined distance or more. For example, when the distance is 1.5 m or more, it is determined that the route of one section acquired in step S712 is a route between warp regions. When the distance is less than 1.5 m, it is determined that it is a normal section (a pair of positions indicating that the pedestrian icon is walking and moving based on its own attribute).

  This is, for example, the distance on the two-dimensional drawing of CAD displayed at 600 in FIG. Since drawings with different floors are often drawn at certain distance intervals (for example, every 1.5 m or more), in this embodiment, when the straight line distance of one section is 1.5 m or more, the section concerned Is determined to be a warp section, but the predetermined distance is not limited to 1.5 m.

  For example, it can be set and changed to an arbitrary distance by accepting a user operation on a setting screen for a predetermined distance (not shown) provided by the evacuation simulation software 120. The predetermined distance value is stored in the external memory 211.

  If one section acquired in step S712 is not a warp section but a normal section, the process proceeds to step S714. If the route of one section acquired in step S712 is a warp section, the process proceeds to step S715.

  In step S714, the evacuation simulation software 120 stores the route data (position pair) for one section acquired in step S712 on the RAM as the route for the normal section. For example, a new number 811 is assigned to 812 in the normal section 810 in FIG. 8 and stored.

  In step S715, the evacuation simulation software 120 stores the route of one section acquired in step S712 on the RAM as the route of the warp section. For example, a new number 821 is assigned to 822 in the warp section 820 of FIG. 8 and stored.

  The evacuation simulation software 120 applies the processing up to step S714 or S715 to all the route data of the pedestrian icon determined as the processing target pedestrian in step S710, and then moves the processing to step S716.

  In step S716, the evacuation simulation software 120 passes the information on the positions of the normal section 810 and the warp section 820 stored in the RAM in step S714 to the CAD software 110, and connects the position data as vertices in order of time series. Instructs to draw a figure (polygon object).

  In addition, an instruction is given to set the color of the polygonal figure to gray 1. Further, the first class on the polygonal CAD software is set as the object ID (for example, “U00001”) of the pedestrian icon being processed, and the second class is instructed to be set to “normal section”.

  At the same time, information on the position of the warp section 820 stored in the RAM in step S715 is transferred to the CAD software 110, and among the vertices of the polygon, the vertices at the position of the warp section are made transparent (transparency is set to 100%). Instruct them to do so.

  A class is one of the units that can select and display a plurality of objects collectively on the CAD software 110. For example, when an operation for selecting an object of the “normal section” class is received on the CAD software 110, the CAD software 110 does not have any pedestrian group object, and all “normal sections” managed by itself. Can be selected at once.

  In step S717, the evacuation simulation software 120 passes the position information of the warp section 820 stored in the RAM in step S715 to the CAD software 110, and draws a line segment (line segment object) having the position data as a vertex for each section. Instruct them to do so.

  In addition, the line segment is instructed to have a gray color of 2. In addition, the first class on the CAD software of the line segment is set as the object ID (for example, “U00001”) of the pedestrian icon being processed, and the second class is instructed to be set to the “warp section”.

  In step S721, the CAD software 110 accepts an object creation instruction. In step S722, a polygon for the normal section is created in accordance with the received object creation instruction for the normal section. And between the vertices of the warp section in the polygon of the normal section is made transparent and displayed on the display screen. In addition, a warp segment line segment is created and displayed in accordance with the received warp segment object creation instruction.

  Specifically, a new object is added to the object information 400 as shown in the object information 420 in FIG.

  In step S718, the evacuation simulation software 120 instructs the CAD software 110 to register the object instructed in steps S716 and S717 in the group of pedestrian icons being processed acquired in step S709. The instruction includes the object ID of the pedestrian icon.

  In step S723, the CAD software 110 receives the instruction. In step S724, the CAD software 110 adds the polygon and line segment objects created in step S722 to the pedestrian group and stores them, as indicated by 830 in FIG. That is, the process which groups an object for every pedestrian is performed. The above is the description of FIG.

  FIG. 10 shows an example of a screen on which the route objects for the warp section and the normal section are created and displayed. Reference numerals 1001 and 1002 denote route objects in the normal section. Reference numerals 1003 and 1004 denote route objects in the warp section.

  As shown at 1010 in FIG. 10, the CAD software 110 receives the click operation of the root object in the 1003 warp section, and thereby the first class of the selected object (the class that has priority over the second class). Select objects of the same class as

  That is, for each pedestrian, it is possible to select an object related to the position history, for example, a route object.

  The class priority can be changed and set in any order on the class order change screen (not shown) of the CAD software 110.

  Moreover, not only grouping as an object of one pedestrian but also assigning different classes to the normal section and the warp section, it is possible to select objects for each of the normal section and the warp section.

  In other words, the evacuation simulation software 120 instructs the CAD software to generate separate route objects for the normal section and the warp section, so that the root object for the normal section and the root object for the warp section can be selected separately. I have control. In addition, control is performed so that display / non-display can be switched collectively.

  For example, as shown in FIG. 11, the CAD software 110 displays a class display setting screen as shown in 1101 and 1111 in response to a user operation.

  Then, as indicated by 1200 in FIG. 12, a “select” button indicated by 1201 is displayed by accepting a right-click operation of the mouse on the display of the normal section, and a press of the “select” button 1201 is accepted. , Select only objects of class in the normal section. A selection frame is shown at 1202.

  In addition, as indicated by 1210 in FIG. 12, a “select” button indicated by 1211 is displayed by accepting a right-click operation of the mouse on the display of the warp section, and a press of the “select” button 1211 is accepted. Select only objects of class in the warp section. A selection frame is shown at 1212.

  In addition to grouping as a single pedestrian object, different classes can be assigned to the normal section and the warp section to enable switching between display and non-display for each of the normal section and the warp section. Become.

  For example, as shown in FIG. 11, the CAD software 110 accepts a click operation for a display / non-display switching check box corresponding to each class on the class display setting screen as shown in 1101 and 1111 to turn on / off the check. Switch the OFF state, and display only objects of the checked class on the drawing.

  11 shows an example in which only the root object in the normal section is displayed. 1110 shows an example of a state in which only the root object in the warp section is displayed.

  In other words, the evacuation simulation software 120 instructs the CAD software to generate separate route objects for the normal section and the warp section, so that the root object for the normal section and the root object for the warp section can be selected separately. I have control.

  Also, by instructing the colors of the root object of the normal section and the root object of the warp section to be different colors, different colors are set for the root object of the normal section and the root object of the warp section, and the root of the normal section Control is performed so that the object and the root object in the warp section are displayed in an identifiable manner.

  In addition, by making the warp section line transparent among the polygonal root objects in the normal section, the warp section object and the normal section object do not appear to overlap each other. This has the effect of making it easier to recognize.

  As described above, according to the first embodiment of the present invention, it is possible to provide a mechanism that makes it possible to easily display the position related to the evacuation of the evacuees according to the position history information.

  For example, it is possible to generate information on a position related to evacuation of the evacuees so that the normal section and the warp section can be selected separately.

  Moreover, it can be set as the information on the position for the evacuation of the difficult person that can switch the display of the normal section and the warp section at once.

  Further, the normal section and the warp section can be displayed in a recognizable manner.

<Second Embodiment>
The evacuation simulation is generally executed for a plurality of pedestrians at once. Therefore, pedestrians may become clogged depending on the evacuation site. When the pedestrian is clogged, the pedestrian coming later cannot move forward, so the evacuation simulation software 120 stops the pedestrian icon coming later.

  In addition, when a plurality of pedestrians are changed in angle and moved, and a pedestrian icon coming later comes into contact with another pedestrian icon, the pedestrian icons do not overlap each other, for example, The position of the icon of the pedestrian who came later may be moved backward (pushed back).

  When the process of moving the pedestrian icon backward is performed near the warp area, for example, as shown by 1310 in FIG. 13, after the pedestrian icon 1313 moves to the warp area 1311 to 1312 and exits from the warp area 1312, As indicated by 1320, the pedestrian icon may return to the warp area 1312.

  Then, the evacuation simulation software 120 determines that a pedestrian has newly entered the warp area, and moves the pedestrian icon 1313 to the warp area 1311. That is, a pedestrian makes a round trip in the same warp area.

  In order to move the pedestrian icon 1313 to the warp area 1312 again, it is necessary to take the pedestrian icon out of the warp area 1311 and enter the warp area 1311 again. Thus, the accuracy of the evacuation simulation is reduced (by removing the pedestrian from the warp area and reentering it). Therefore, a pedestrian staying in the same warp area for a certain time (for example, 1 second) may be warped again to the other warp area that is a pair of the warp area. The longer the stay, the more round trips between warp areas. As a result, when a route object is created according to the simulation result, as shown by reference numeral 1301 in FIG. 13, an unnecessarily large number of route objects indicating reciprocation between warp areas are generated and displayed. Since the root object between the warp areas is for confirming from which warp area the pedestrian icon has moved to which warp area, one route object is sufficient for each pair of warp areas.

  In the second embodiment, an object is to provide a mechanism that can appropriately display a root object in a warp section.

  Note that descriptions of processes, data, and screens common to the first embodiment are omitted.

  If it is determined in step S713 in FIG. 7 that the section acquired in step S712 is a warp section, the evacuation simulation software 120 requests the CAD to acquire a warp area object list and stores it in the RAM. Then, it is determined with reference to the warp section 820 whether there is a warp section that spans between the same warp areas as the two warp areas where the coordinates of both ends of the warp section are located within a predetermined time in the past (for example, within one second). .

  If there is a warp section that spans the same warp area, that is, a section (warp) indicating that the section acquired in step S712 is moving again between the same warp areas as two warp areas that have been warped in the past. In the case of a return trip in the round trip between areas or the second outgoing trip), the section information acquired in step S712 is discarded without being stored in the warp section 820, and the process proceeds to step S712.

  With this process, it is possible to reduce the possibility of generating a plurality of root objects by reciprocating between the same warp areas.

  Therefore, it is possible to provide a mechanism that can appropriately display the root object in the warp section, for example, as indicated by 1000 in FIG. 10 without creating and displaying a complicated object as indicated by 1300.

<Third Embodiment>
The evacuation simulation is generally executed for a plurality of pedestrians at once. Therefore, although it can move at a normal walking speed depending on the place, the walking speed may decrease in a place where pedestrians are jammed.

  Possible causes of pedestrian clogging include narrow roads, door size and design, and lead wires for movement. The user of the evacuation simulation software may confirm the result of the evacuation simulation and consider the design of the building or road so as to improve such factors as the narrowness of the road.

  In the third embodiment, it is an object to provide a mechanism that can easily display a position related to evacuation of an evacuee according to speed information specified from a position history.

  Hereinafter, the third embodiment of the present invention will be described with reference to FIGS. 14 and 15. Note that descriptions of processes, data, and screens common to the first and second embodiments are omitted.

  The evacuation simulation software 120 executes the process of FIG. 14 instead of step S716 of FIG.

  In step S <b> 1401, the evacuation simulation software 120 acquires unprocessed head data (data that has elapsed earliest from the start of simulation) in the normal section 810.

  In step S1402, the evacuation simulation software 120 specifies the speed of the pedestrian who has moved the length of the acquired section. For example, the speed of the pedestrian when the section is moved within 0.1 seconds is specified. And it is determined whether the speed of the pedestrian of the said area is more than predetermined speed. The predetermined speed is assumed to be a normal movement speed of the pedestrian. When the speed of the pedestrian in the section is equal to or higher than the predetermined speed, the process proceeds to step S1403.

  The section data indicates the position of the movement source and the movement destination per unit time (for example, per 0.1 second). That is, the determination of whether or not the movement speed of the pedestrian in the section is equal to or higher than the normal movement speed of the pedestrian means that the distance in the section moves when the pedestrian moves at the normal movement speed. This is the determination. If the distance is shorter than the distance traveled when the pedestrian moves at a normal moving speed, it means that the section has moved at a speed slower than the normal moving speed.

  In step S1403, the evacuation simulation software 120 determines the data of the section as data of a section in which the pedestrian has moved at a speed (first speed) equal to or higher than the normal moving speed and stores the data on the RAM. For example, it memorize | stores in the area information list of the 1st speed group not shown.

  When the speed of the pedestrian in the section is less than the normal movement speed (first speed) of the pedestrian, the data in the section is compared with the speed that the pedestrian is slower than the normal movement speed (second Is determined as data of a section moved at a speed of (5)) and stored in the RAM. For example, it is stored in the section information list of the second speed group (not shown) (step S1404).

  In step S1405, the evacuation simulation software 120 passes the information on the position of the first speed section, the information on the position of the second speed section, and the information on the position of the warp section 820 to the CAD software 110. Instructs to draw one polygon figure (polygon object) connecting the position data as vertices in order.

  Also, the color is set to gray 3, the pedestrian ID is set to the first class, “normal section” is set to the second class, and “first speed” is set to the third class. Instruct.

  In addition, an instruction is given to set the transparency of the second segment and the warp segment among the line segments in the polygon to 100%.

  The CAD software 110 accepts the instruction in step S721, and creates and displays a route object for the first section according to the accepted instruction (step S722).

  In step S1406, the evacuation simulation software 120 delivers the position information of the first speed section, the position information of the second speed section, and the position information of the warp section 820 to the CAD software 110, and performs time series. Instructs to draw one polygon figure (polygon object) connecting the position data as vertices in order.

  Also, the color is set to gray 4, the pedestrian ID is set to the first class, “normal section” is set to the second class, and “second speed” is set to the third class. Instruct. Thereafter, the process proceeds to step S717 in FIG.

  In addition, an instruction is given to set the transparency of the first segment and the warp segment out of line segments in the polygon to 100%.

  The CAD software 110 accepts the instruction in step S721, and creates and displays a route object for the first section according to the accepted instruction (step S722).

  By the processing in steps S1405 and S1406, a route object corresponding to the pedestrian icon is created so as to be separately selectable according to the moving speed (walking speed) of the pedestrian.

  In addition, the route object corresponding to the pedestrian icon can be identified and displayed according to the moving speed (walking speed) of the pedestrian.

  Therefore, the user of the evacuation simulation software can easily confirm the place where the speed of the pedestrian has decreased and the place of the normal speed as a result of the evacuation simulation in the design examination.

  An example of creating and displaying an object for each speed is shown in FIG. For example, 1501 is a root object of the first speed group, and 1502 is a root object of the second speed group.

  As described above, according to the third embodiment of the present invention, there is provided a mechanism that can easily display the position related to the evacuation of the evacuees according to the speed information specified from the position history. can do.

  As described above, according to the present invention, it is possible to provide a mechanism that makes it possible to easily display a position related to the evacuation of an evacuee according to information on a position history.

<Other embodiments>
In the above-described embodiment, the evacuee is described as a pedestrian, but the evacuee is not necessarily limited to a pedestrian. For example, when a person icon is moved on a vehicle, the icon of the person appearing on the vehicle indicates an refugee.

  Further, in the above-described embodiment, in consideration of reducing the labor for selecting an object, the root object of the normal section is generated as a polygon and the process of making the warp section transparent is performed. A plurality of squares may be generated for each warp section. Specifically, the evacuation simulation software 120 passes only the data of the normal section 810 to the CAD software 110 in step S716, and instructs to create a plurality of polygons that connect consecutive sections. Thereby, the process which makes only the line segment of a warp area transparent can be abbreviate | omitted.

  Further, in the above-described embodiment, it is instructed to set the object ID of the pedestrian icon, the normal section, and the class of the warp section to each root object. However, for example, each object is selected or displayed / displayed using a layer. You may make it easy to switch non-display. Specifically, the evacuation simulation software 120 instructs the CAD software 110 to create a “normal section” layer for the drawing in step S716, and the route object of the normal section is created in the created “normal section” layer. The CAD software 110 is instructed to belong. In step S717, the CAD software 110 is instructed to create a “warp section” layer for the drawing, and the CAD software 110 is instructed to make the root object of the warp section belong to the created “warp section” layer. To do. The CAD software 110 creates an object and each layer according to the instruction, and stores each root object in association with each layer. The CAD software 110 is provided with a function for switching the display / non-display of objects for each layer and a function for selecting only objects belonging to a specific layer at a time. The root object of the warp section can be selected separately. In addition, the root object of the normal section and the root object of the warp section can be displayed / hidden all at once.

  In addition, the root object in the warp section indicates from which warp area the pedestrian has moved to which warp area. For this reason, for example, a simple diagram with a small warp area may not be displayed.

  Therefore, for example, the root object in the warp section may be initially hidden. Specifically, in step S717, the evacuation simulation software 120 instructs the CAD software 110 to hide the created warp section route object, and the CAD software 110 removes the warp section root object according to the instruction. Display only the root object of the normal section. In the CAD software 110, it is possible to select a class for selecting the root object in the warp section and switch between display and non-display. This allows the user to confirm that there are two different sections, which are the section where the pedestrian is not walking and the section where the pedestrian has walked.

  In addition, in the case of a simple diagram in which the number of root objects in the warp section is small, that is, the warp area is small, the root objects in the warp section may be hidden. Specifically, in step S717, the evacuation simulation software 120 counts the number of objects in the warp section instructed to create and determines whether the number is equal to or less than a predetermined number. It is assumed that the predetermined number of values is stored in advance in the external memory (for example, 10). The evacuation simulation software 120 instructs the CAD software 110 to hide the generated warp section route object when the number of root objects in the warped section instructed to create is less than a predetermined number. According to the instruction, the root object in the warp section is hidden and only the root object in the normal section is displayed. When the number of root objects in the warp section instructed for creation is greater than a predetermined number, the CAD software 110 is instructed to display the root objects in the created warp section. The CAD software 110 displays the root object in the warp section according to the instruction.
