(1-3-2) Software Configuration FIG. 3B is a block diagram showing the software configuration of the barrier-free information providing server 20 in association with the hardware configuration shown in FIG. 3A.

The control device 220 is composed of the hardware processor 220A and the program memory 220B, and includes a user-corresponding processing unit 221, a passage difficulty data calculation unit 222, a correction value setting processing unit 223, and a correction value setting processing unit 223 as processing function units by software. It is equipped with a barrier-free information providing unit 224. All of these processing function units are realized by causing the hardware processor 220A to execute a program stored in the program memory 220B. It should be noted that these processing function units may be realized by separate hardware processors. That is, the barrier-free information providing server 20 may include a plurality of hardware processors. In addition, at least a part of these control functions is a variety of other hardware circuits including integrated circuits such as ASIC (Application Specific Integrated Circuit), FPGA (field-programmable gate array), and GPU (Graphics Processing Unit). It may be realized in the form of.

The storage device 230 is provided with a user data storage unit 231, a collected data storage unit 232, a score data storage unit 233, and a passage difficulty data storage unit 234.

As will be described in detail later, the user-corresponding processing unit 221 exchanges various data with the information supply terminal 10 via the data transmission network NW using the communication interface device 210, and the user data storage unit 231 and the user data storage unit 231 for that purpose. Data is stored and read out to the collected data storage unit 232.

The user data storage unit 231 stores the information of the information provider who provides the measurement data by using the information supply terminal 10. FIG. 4A is a diagram showing an example of the stored contents of the user data storage unit 231. Here, it is shown in a table format, but it goes without saying that it is not limited to this. The user data storage unit 231 sets each information provider as one record, for example, user ID, authentication information, category, acquired points, unsent points, cooperation flag (indicated as cooperation F in the figure), and continuation flag (continuation in the figure). (Indicated as F), etc. are memorized.

The user ID is a unique number assigned to each information provider to identify the information provider. The authentication information is a personal identification number arbitrarily set by the information provider in advance. The user handling processing unit 221 authenticates the information provider by determining a match between the authentication information transmitted from the information supply terminal 10 and the stored authentication information. The category is information on the provider category, and corresponds to the user category based on the difficulty of passage of service users who require barrier-free information such as walking, wheelchairs, strollers, and bicycles. .. This provider category is also data arbitrarily set by the information provider in advance, but can be changed, for example, one information provider can walk at a certain point, bicycle at a certain point, and stroller at a certain point. It is data. The user correspondence processing unit 221 rewrites this category in response to a setting instruction from the information supply terminal 10.

The earned points indicate the total number of points earned by the information provider so far. The user-corresponding processing unit 221 assigns points according to the amount of measurement data transmitted from the information supply terminal 10 of the information provider, and adds and updates the points of the information provider.

The unsent point indicates a point value that has not yet been transmitted to the map providing server 30 or another point management server. The user-corresponding processing unit 221 transmits the unsent points to the map providing server 30 or another point management server at the point transmission timing every few seconds to several minutes, and then clears the unsent points.

The cooperation flag is a flag indicating whether or not there has been a survey cooperation application for an uninvestigated point from the relevant information provider. When the user correspondence processing unit 221 determines that the communication interface device 210 has received the investigation cooperation application from the information supply terminal 10 via the data transmission network NW, the user correspondence processing unit 221 sets this cooperation flag (the circle mark in the figure is in the set state). (The same applies to other flags). The continuation flag is a flag indicating whether or not an uninvestigated point is being investigated in response to an application for cooperation in investigation. The user response processing unit 221 determines whether or not the uninvestigated point is being investigated in response to the investigation cooperation application, and sets this continuation flag.

The collected data storage unit 232 stores the collected data collected from a plurality of information providers. FIG. 4B is a diagram showing an example of the stored contents of the collected data storage unit 232. Here, it is shown in a table format, but it goes without saying that it is not limited to this. The collected data storage unit 232 sets each measurement data as one record, for example, measurement date and time, latitude / longitude data representing a position, measurement values of acceleration x-axis, y-axis, and z-axis, x-axis of angular velocity, and y-axis. , Z-axis measured values, provider category, caution information, low reliability flag (indicated as continuation F in the figure), etc. are stored.

The low reliability flag is a flag indicating whether or not the collected data of the record is collected data older than a certain period from the current date and time. The user correspondence processing unit 221 compares the current date and time with the measurement date and time of the collected data, and sets this low reliability flag as the old data is considered to be unreliable.

The caution information is information designated by the information provider by operating the information supply terminal 10, and the user correspondence processing unit 221 is designated by the information supply terminal 10 via the data transmission network NW received by the communication interface device 210. This caution information is stored in the collected data storage unit 232 according to the above. The caution information includes information predetermined as options such as steps, slopes, sidewalk widths, and detours, and a plurality of, for example, three stages of information can be stored according to the degree of caution in the state. Further, the caution information can include character information in which the information provider freely inputs a state to be noted that is not included in the options.

When the free input character information is stored as caution information in the collected data storage unit 232, the correction value setting processing unit 223 displays the character information on the display device 250, and the administrator of the barrier-free information providing server 20. However, the content displayed on the display device 250 is confirmed, and the correction coefficient input from the input device 240 according to the content is stored in the collected data storage unit 232. If the administrator is configured to confirm the character information and input the correction coefficient via the data transmission network NW by a tablet terminal or the like, the barrier-free information providing server 20 includes an input device 240 and a display device 250. It doesn't have to be. Alternatively, the correction value setting processing unit 223 may derive the correction coefficient from the character information by using AI or the like, and even in such a configuration, the barrier-free information providing server 20 may use the input device 240. And the display device 250 may not be provided.

The passage difficulty data calculation unit 222 calculates the passage difficulty data based on the collected data stored in the collected data storage unit 232.

The score data storage unit 233 stores the variation score data for each area mesh for each of the provider categories. FIG. 4C is a diagram showing an example of the stored contents of the score data storage unit 233. Here, it is shown in a table format, but it goes without saying that it is not limited to this. The score data storage unit 233 sets each area mesh as one record for each provider category, for example, area mesh position, acceleration x-axis, y-axis, z-axis variation score data, and angular velocity x-axis, y-axis. , Z-axis variation score data is stored.

The area mesh is a geographical area divided into a mesh shape having a predetermined size. The score data storage unit 233 stores the area mesh position as the latitude / longitude of the northwestern end thereof. The variation score data is a plurality of aggregated acceleration and angular velocity measured values stored in the collected data storage unit 232 when aggregated for each area mesh corresponding to the measured values for each provider category. It represents the degree of variation in the movement of the information supply terminal 10 included in the measured value. The variation score data is calculated by the passage difficulty data calculation unit 222 based on the collected data stored in the collected data storage unit 232 and stored in the score data storage unit 233.

The passage difficulty data storage unit 234 stores data representing the passage difficulty in each provider category for each area mesh. FIG. 4D is a diagram showing an example of the storage contents of the passage difficulty level data storage unit 234. Here, it is shown in a table format, but it goes without saying that it is not limited to this. The passage difficulty data storage unit 234 stores the passage difficulty data of each provider category with each area mesh as one record.

The passage difficulty level data is the variation score of the calculated variation score when the average value of the variation score of each provider category is calculated for each area mesh based on the variation score data stored in the score data storage unit 233. It is an average value. The passage difficulty level data is calculated by the passage difficulty level data calculation unit 222 based on the variation score data stored in the score data storage unit 233, and stored in the passage difficulty level data storage unit 234.

The barrier-free information providing unit 224 is stored in the passage difficulty level data storage unit 234 in response to a request from the map providing server 30 via the data transmission network NW using the communication interface device 210, as will be described in detail later. Barrier-free information is generated based on the traffic difficulty level data, and the generated barrier-free information is transmitted to the map providing server 30 via the data transmission network NW by the communication interface device 210.

The communication interface device 310, the program memory 320B, and the storage device 330 are connected to the hardware processor 320A via the bus 340.

The communication interface device 310 includes, for example, one or more wired or wireless communication interface units, and according to the communication protocol used in the data transmission network NW, the barrier-free information providing server 20, the service providing store terminal 40, and the service use. It enables transmission and reception of various information with the user terminal 50 and other external devices (not shown). As the wired interface, for example, a wired LAN is used, and as the wireless interface, for example, a wireless LAN, an interface adopting a low power wireless data communication standard such as Bluetooth, or the like is used.

The program memory 320B uses, for example, a non-volatile memory such as an HDD or SSD that can be written and read at any time and a non-volatile memory such as a ROM as a storage medium, and is a hardware processor 320A such as a CPU. Stores the programs required to execute various control processes by executing.

It is used to store various data acquired and created in the process of performing.

The storage device 330 is provided with a user data storage unit 331, a store data storage unit 332, a map data storage unit 333, and a route data storage unit 334. The user data storage unit 331 stores the information of the service user who uses the guidance information by the service user terminal 50. The store data storage unit 332 stores the information of the contract store. The map data storage unit 333 stores map data. It is not necessary to include the map data storage unit 333 by acquiring and using the map data from an external map system that provides the map data. The route data storage unit 334 was calculated based on the barrier-free information acquired from the barrier-free information providing server 20 via the data transmission network NW using the communication interface device 310 and the map data stored in the map data storage unit 333. Store route data.

(2) Operation Next, the operation of the barrier-free route providing system configured as described above will be described.

(2-1) Data Collection FIG. 6A is a flowchart showing a processing procedure of background processing executed in the information supply terminal 10. In the smartphone SP, a barrier-free investigation cooperation application for making the smartphone SP stored in the storage device 130 function as the information supply terminal 10 is executed by the hardware processor 120A, and when a predetermined authentication operation is completed, the hardware processor 120A Continues to perform this background processing regardless of the startup status of other applications. Further, in the sensor terminal ST, the barrier-free investigation cooperation program stored in the program memory 120B can be executed by the hardware processor 120A when the power is turned on.

In this background processing, the hardware processor 120A determines whether or not the collection timing has come (step S101). The collection timing can be, for example, every 20 milliseconds. If it is determined that the collection timing has come, the hardware processor 120A detects the acceleration data and the angular velocity data by the inertial sensor 170 (step S102), and also detects the position data by the position sensor 180 (step S103). In the smartphone SP not provided with the inertial sensor 170 or the position sensor 180, the acceleration data and the angular velocity data or the position data may be detected from the sensor SD via the communication interface device 110. Then, the hardware processor 120A performs the measurement data including the detected measurement data and the position data and the current date and time data measured by the clock (not shown) together with the information indicating the information provider of the information supply terminal 10 together with the communication interface device 110. Is transmitted to the barrier-free information providing server 20 via the data transmission network NW (step S104).

After that, the hardware processor 120A determines whether or not a predetermined end operation has been performed (step S105), and if it determines that the end operation has not been performed, repeats the process from step S101. If it is determined that the end operation has been performed, this background processing is terminated.

In this way, the information supply terminal 10 transmits measurement data to the barrier-free information providing server 20 at regular time intervals (for example, 20 milliseconds).

FIG. 6B is a flowchart showing a processing procedure of the main processing of the barrier-free investigation cooperation application or the barrier-free investigation cooperation program executed in the information supply terminal 10. When the barrier-free survey cooperation application or program is started, the hardware processor 120A inquires about the current user status from the barrier-free information providing server 20 via the data transmission network NW using the communication interface device 110 (step S111). .. That is, it inquires what the current state of the information provider of the information supply terminal 10 is. In response to this inquiry, the barrier-free information providing server 20 returns the total points earned by the information provider up to the present and the information of the provider category. The hardware processor 120A receives this from the communication interface device 110 and displays it on the liquid crystal display 140 (step S112).

FIG. 7A is a diagram showing an example of a main screen presented to the information provider at this time. As shown in the figure, the main screen 141 has a point display area 1411 for displaying the points earned by the information provider up to now, and a category display area 1412 for displaying the provider category of the information provider. .. Further, the main screen 141 displays a category change button 1413, a cooperation button 1414, and a caution button 1415 as buttons operated by the information provider. The category change button 1413 is a button for instructing the change of the provider category. The cooperation button 1414 is a button for indicating the intention to cooperate in the investigation of the uninvestigated point. The attention button 1415 is a button for positively reporting a state to be noted.

After displaying the points earned and the provider category up to now in step S112, the hardware processor 120A waits for the operation of these buttons 1413 to 1415. That is, the hardware processor 120A first determines whether or not the category change button 1413 has been operated (step S113). If it is determined that the category change button 1413 has not been operated, the hardware processor 120A determines whether or not the cooperation button 1414 has been operated (step S114). If it is determined that the cooperation button 1414 has not been operated, the hardware processor 120A determines whether or not the caution button 1415 has been operated (step S115). If it is determined that the caution button 1415 is also not operated, the hardware processor 120A repeats the process from step S111. As a result, the hardware processor 120A inquires about the current state of the user to the barrier-free information providing server 20, acquires the information of the changed points in the above step S121, and displays it on the liquid crystal display 140. it can. That is, the measurement data is transmitted to the barrier-free information providing server 20 at regular intervals by the background processing described above, and the information provider can easily confirm the updated points in the point display area 1411. it can.

Then, if it is determined in step S113 that the category change button 1413 has been operated, the hardware processor 120A causes the liquid crystal display 140 to display the category selection screen (step S116). Although this category selection screen is not shown in particular, a predetermined list of provider categories is displayed as options so that the information provider can select a new provider category. Alternatively, instead of switching to the category selection screen, the provider category options may be displayed as a pull-down menu below the category change button 1413. When the hardware processor 120A receives the selection input of the new provider category (step S117), the hardware processor 120A uses the communication interface device 110 to transfer the selected provider category to the barrier-free information providing server 20 via the data transmission network NW. (Step S118). After that, the hardware processor 120A inquires about the current state of the user to the barrier-free information providing server 20 by returning the process to step S111, and acquires the information of the changed provider category in step S121. , It can be displayed on the liquid crystal display 140.

Further, if it is determined in step S114 that the cooperation button 1414 has been operated, the hardware processor 120A uses the communication interface device 110 to send a cooperation inquiry to the barrier-free information providing server 20 via the data transmission network NW. Transmit (step S119). This cooperation inquiry includes position information indicating the position of the information supply terminal 10. In response to this cooperation inquiry, the barrier-free information providing server 20 returns map information for the cooperation screen. The hardware processor 120A receives this by the communication interface device 110, and displays the cooperation screen using the map information on the liquid crystal display 140 (step S120).

FIG. 7B is a diagram showing an example of a cooperation screen presented to the information provider at this time. As shown in the figure, the cooperation screen 142 displays a map display area 1421 and a back button 1422. The map information displayed in the map display area 1421 is the current position mark 1423 indicating the current position of the information supply terminal 10, that is, the information provider, and the point where the measurement data has already been collected on the map near the information supply terminal 10. It is a superimposition of the collected mark 1424 indicating. By confirming the map information displayed in the map display area 1421, the information provider can know the points where the measurement data has not been collected. In this example, the collected points are identified and displayed, but conversely, the uncollected points may be identified and displayed. In the present embodiment, as will be described later, the information provider is more likely to transmit the measurement data of the uncollected points than when the measurement data of the collected points is transmitted to the barrier-free information providing server 20. The points are given to the information provider so as to motivate them to collect the measurement data of the uncollected points. Further, the uncollected points can include not only the cases where the data is not actually collected but also the points where the data is out of date even if the data has been collected. The back button 1422 is a button for instructing to return to the main screen 141 which is the previous screen.

After displaying the cooperation screen 142 on the liquid crystal display 140 in step S120, the hardware processor 120A is waiting for the operation of the back button 1422 (step S121). When it is determined that the back button 1422 has been operated, the hardware processor 120A returns to the display of the main screen 141 by returning the process to step S111.

If it is determined in step S115 that the caution button 1415 has been operated, the hardware processor 120A causes the liquid crystal display 140 to display the caution content selection screen (step S122).

FIG. 7C is a diagram showing an example of this caution content selection screen. As shown in the figure, the caution content selection screen 143 displays a plurality of selection buttons 1432 according to the degree of caution for each predetermined caution content option 1431, and here, the three-stage selection button 1432 is not included in the options. It displays a character information input area 1433 for the information provider to freely input a state to be noted. Note that the contents of the caution content option 1431 and each selection button 1432 may be configured to be changed according to the provider category.

When the caution content is selected by operating any of the selection buttons 1432 on the caution content selection screen 143 or the character information of the caution content is input to the character information input area 1433 (step S123), the hardware processor 120A communicates. Using the interface device 110, the caution content is transmitted to the barrier-free information providing server 20 via the data transmission network NW (step S124). After that, the hardware processor 120A returns to the display of the main screen 141 by returning the process to step S111.

FIG. 8A is a flowchart showing a processing procedure of information collection processing executed by the user-corresponding processing unit 221 of the barrier-free information providing server 20.

The user-corresponding processing unit 221 first waits for the communication interface device 210 to receive measurement data from any of the information supply terminals 10 via the data transmission network NW (step S201). As described above, the information supply terminal 10 transmits measurement data at regular intervals.

When it is determined that the measurement data from any of the information supply terminals 10 has been received, the user response processing unit 221 uses the user according to the information indicating the information provider of the information supply terminal 10 of the provider transmitted together with the measurement data. The provider category of the information provider is acquired from the data storage unit 231 and the measurement data received together with the provider category is stored in the collection data storage unit 232 (step S202). Further, the user correspondence processing unit 221 gives points according to the provider category to the information provider (step S203). That is, in the present embodiment, points are given by weighting according to the provider category. This is because the data collected from a person who has a high degree of difficulty in passing, such as a wheelchair, and whose measurement data cannot be easily obtained, is more useful information for the service user. The user-corresponding processing unit 221 adds the points to be given to the acquired points and undelivered points of the information provider stored in the user data storage unit 231.

After that, the user correspondence processing unit 221 determines whether or not this measurement data is a new collection point (step S204). When it is determined that it is not a new collection point, the user correspondence processing unit 221 determines whether or not the continuation flag of the information provider in the user data storage unit 231 is set (step S205).

When it is determined that the continuation flag is not set, the user response processing unit 221 compares the measurement date and time of each measurement data stored in the collected data storage unit 232 with the current date and time measured by a clock (not shown). It is determined whether or not there is collected data, that is, unreliable information that is older than a certain period from the current date and time (step S206). If there is low reliability information, the low reliability flag is set for the measurement data (step S207).

After that, or when it is determined in step S206 that there is no low reliability information, the user-corresponding processing unit 221 determines whether or not a certain amount of collected data has been acquired in the collected data storage unit 232, that is, a certain amount of measurement data is stored. It is determined whether or not it has been accumulated (step S208). At this time, the measurement data for which the low reliability flag is set may be excluded from the accumulated amount of the measurement data. Here, when it is determined that a certain amount of measurement data has not yet been accumulated, the user correspondence processing unit 221 determines whether or not the point transmission timing has come (step S209). If it is determined that it is not the point transmission timing, the user correspondence processing unit 221 returns the processing to the above step S201.

On the other hand, when it is determined that it is the point transmission timing, the user correspondence processing unit 221 uses the communication interface device 210 to transmit the untransmitted points of each information provider stored in the user data storage unit 231 to the data transmission network. It is transmitted to the map providing server 30 or another point management server via the NW (step S210). Then, after deleting the transmitted points from the user data storage unit 231 (step S211), the processing is returned to the above step S201.

Further, when it is determined in step S204 that it is a new collection point, the user correspondence processing unit 221 determines whether or not the cooperation flag of the information provider in the user data storage unit 231 is set (step). S212). If it is determined that the cooperation flag is not set, the user correspondence processing unit 221 proceeds to the process in step S206.

In this way, the user correspondence processing unit 221 collects the measurement data transmitted by the background processing of each information supply terminal 10.

FIG. 8B is a flowchart showing a processing procedure of user-corresponding processing executed by the user-corresponding processing unit 221 of the barrier-free information providing server 20. The user correspondence processing unit 221 can execute this user correspondence processing in parallel with the information collection processing.

In this user correspondence process, the user correspondence processing unit 221 determines whether or not the communication interface device 210 has received the user status inquiry from any information supply terminal 10 via the data transmission network NW (step S231). .. As described above, the information supply terminal 10 transmits a user status inquiry in the step S111 of the main process. When it is determined that the user status inquiry has been received, the user response processing unit 221 reads the acquisition points and the provider category of the information provider of the information supply terminal 10 from the user data storage unit 231 and data by the communication interface device 210. It is transmitted to the information supply terminal 10 of the inquiry source via the transmission network NW (step S232).

After that, or when it is determined in step S231 that the user status inquiry has not been received, the user response processing unit 221 selects from any information supply terminal 10 via the data transmission network NW by the communication interface device 210. It is determined whether or not the category has been received (step S233). As described above, the information supply terminal 10 may transmit the selected category in the step S118 of the main process. When it is determined that the selected category has been received, the user handling processing unit 221 updates the provider category of the information provider stored in the information supply terminal 10 to the selected category (step S234).

After that, or when it is determined in step S233 that the selected category has not been received, the user response processing unit 221 makes a cooperative inquiry from any information supply terminal 10 via the data transmission network NW by the communication interface device 210. Is determined (step S235). As described above, the information supply terminal 10 may transmit a cooperation inquiry in the step S119 of the main process.

Here, when it is determined that the cooperation inquiry has not been received, has the user response processing unit 221 received the caution content from any information supply terminal 10 via the data transmission network NW by the communication interface device 210? It is determined whether or not (step S236). As described above, the information supply terminal 10 may transmit the caution content in the step S124 of the main process. When it is determined that the caution content has been received, the user response processing unit 221 stores the received caution content in correspondence with the measurement data of the corresponding position in the collected data storage unit 232 (step S237). Then, the point of the information provider of the information supply terminal 10 of the transmission source of the caution content is updated (step S238). That is, the granted points are added to the acquired points and unsent points of the information provider stored in the user data storage unit 231.

After that, or when it is determined in step S236 that the caution content has not been received, the user response processing unit 221 returns the process to step S231.

FIG. 8C is a flowchart showing a processing procedure of the correction value setting process executed by the correction value setting processing unit 223 of the barrier-free information providing server 20.

As described above, the caution information stored in the collected data storage unit 232 by the user correspondence processing unit 221 in the step S237 is stored in the character information input area 1433 of the caution content selection screen 143 by the information provider in the information supply terminal 10. It may include textual information of the entered caution content. Therefore, the correction value setting processing unit 223 reads out the caution content stored as free input of the caution information from the collected data storage unit 232 (step S251) and displays it on the display device 250 (step S252). Then, the administrator of the barrier-free information providing server 20 who has confirmed this character information inputs the correction value using the input device 240 (step S253). The correction value setting processing unit 223 stores the input correction value in the collected data storage unit 232 in correspondence with the character information (step S254).

In this way, the barrier-free information providing server 20 collects measurement data from each information supply terminal 10.

(2-2) Data collection at uncollected points As described above, from the information supply terminal 10 in step S119 of the main process of the information supply terminal 10 for the purpose of cooperating with the information provider in collecting data at the uncollected points. You can send a cooperation inquiry.

When it is determined in step S235 of the user correspondence process shown in FIG. 8B that the cooperation inquiry has been received, the user correspondence processing unit 221 uses the communication interface device 210 to send the map providing server 30 to the map providing server 30 via the data transmission network NW. Request the transmission of map data near the position of the information supply terminal 10 of the cooperation inquiry source (step S239). Then, the user correspondence processing unit 221 acquires the map data transmitted from the map providing server 30 via the data transmission network NW in response to the request (step S240). That is, the map data received by the communication interface device 210 is stored in a temporary storage area (not shown) of the storage device 230. After that, the user-corresponding processing unit 221 refers to the collected data storage unit 232 and determines, among the points included in the map data, the points for which the measurement data has been collected (step S241). At this time, the measurement data for which the low reliability flag is set may be excluded from the collected points. Then, the identification data representing the determined collected points is superimposed on the map data (step S242), and is transmitted by the communication interface device 210 to the information supply terminal 10 of the cooperation inquiry source via the data transmission network NW (step S243). ). As a result, the information supply terminal 10 can display the map information in the map display area 1421 on the cooperation screen 142 as shown in FIG. 7B. The information supply terminal 10, that is, the current position of the information provider may be superimposed on the map transmitted by the user handling processing unit 221, or the information supply terminal 10 may superimpose the own position. Then, the user correspondence processing unit 221 sets the cooperation flag of the corresponding information provider of the user data storage unit 231 (step S244). After that, the user-corresponding processing unit 221 proceeds to the process in step S236.

In this way, the information provider who confirmed the uncollected points by the information supply terminal 10 of the cooperation inquiry source passes through the uncollected points, and the measurement data is distributed to the barrier-free information providing server by the background processing of the information supply terminal 10. It is sent to 20.

Then, in step S204 of the information collection process shown in FIG. 8A, the user correspondence processing unit 221 determines that it is a new collection point. In this case, as described above, the user correspondence processing unit 221 determines in step S212 whether or not the cooperation flag of the information provider in the user data storage unit 231 is set. When receiving a cooperation inquiry from the information supply terminal 10, the cooperation flag of the corresponding information provider of the user data storage unit 231 is set in step S244. Therefore, here, it is determined that the cooperation flag is set. When it is determined that the cooperation flag is set, the user correspondence processing unit 221 sets the continuation flag of the corresponding information provider of the user data storage unit 231 (step S213). An information provider who has confirmed an uncollected point by the information supply terminal 10 tries to pass through the uncollected point, but must pass through the point where the measurement data has been collected before reaching the uncollected point. In some cases. Therefore, when the uncollected point is reached, a flag is set to indicate that the measurement data of the uncollected point is being collected by the cooperation inquiry. After that, the user-corresponding processing unit 221 grants additional points in addition to the normal point grant in step S203 (step S214). As a result, the information provider can be motivated to collect the measurement data of the uncollected points. After that, the user-corresponding processing unit 221 proceeds to the process in step S206.

In this way, when the information provider passes through the uncollected point, it reaches the point where the measurement data has already been collected. From here, it is necessary to switch to normal point awarding without additional points. Therefore, when it is determined in step S204 that it is not a new collection point, the user response processing unit 221 determines in step S205 whether or not the continuation flag of the information provider in the user data storage unit 231 is set. To do. Then, when it is determined that the continuation flag is set, the user correspondence processing unit 221 resets the cooperation flag and the continuation flag of the information provider in the user data storage unit 231 (step S215). After that, the user-responsive processing unit 221 displays a message of thanks for cooperation on the display device 250 (step S216), and proceeds to the process in step S206.

(2-3) Calculation of Passage Difficulty Data When it is determined in step S208 of the information collection process shown in FIG. 8A that a certain amount of measurement data has been accumulated in the collected data storage unit 232, the user response processing unit 221 determines. Have the passage difficulty data calculation unit 222 calculate the passage difficulty data. The passage difficulty data calculation unit 222 calculates the passage difficulty data by using, for example, the method disclosed in Patent Document 1.

That is, the passage difficulty data calculation unit 222 divides the measurement data stored in the collection data storage unit 232 into each area mesh (step S217). This is a process of associating each measurement data with any of the predefined area meshes, in other words, aggregating the measurement data measured at the same position. The area mesh is, for example, a geographical area having a latitude of 0.0001 and a longitude of 0.0001 on one side.

Then, the passage difficulty data calculation unit 222 calculates the variation score for each area mesh for each provider category, and stores the calculated variation score in the score data storage unit 233 (step S218). That is, the passage difficulty data calculation unit 222 aggregates the measurement data continuously measured by the movement of the same information provider in the same mesh as one unit based on the position data included in the measurement data. To do. Next, for each aggregated measurement data, the measurement data generated by the passage of each information provider for each area mesh is merged for each provider category, and the variation of the measurement data is calculated for each area mesh. Then, a process for calculating the variation score is executed based on the variation measurement data. For example, normalization is used as a method for calculating the variation score. In this way, as shown in FIG. 4C, the score data storage unit 233 stores the variation score for each area mesh for each provider category. At this time, the measurement data for which the low reliability flag is set may be excluded from the target of this score calculation.

Next, the passage difficulty data calculation unit 222 calculates the passage difficulty data for each area mesh for each category, and stores the calculated passage difficulty data in the passage difficulty data storage unit 234 (step S219). That is, the passage difficulty data calculation unit 222 calculates the average value of the scores for each category for each area mesh based on the variation score data stored in the score data storage unit 233, and the calculated average value for each category is calculated. For example, the average value of the scores is stored in the passage difficulty data storage unit 234 as the passage difficulty data indicating the passage difficulty of the area mesh. In this way, as shown in FIG. 4D, the passage difficulty data storage unit 234 stores the passage difficulty data for each provider category for each area mesh.

After that, the passage difficulty data calculation unit 222 corrects the passage difficulty data for each provider category based on the caution information, and updates the stored contents of the passage difficulty data storage unit 234 with the correction result (step S220). .. That is, the passage difficulty data calculation unit 222 refers to each point stored in the collected data storage unit 232 with respect to the passage difficulty data for each provider category stored in the passage difficulty data storage unit 234. Add correction based on the caution information of. In this correction, the correction coefficient according to the number of steps is applied to the caution information selected from a plurality of predetermined steps such as steps and inclinations, and the caution information based on the freely input character information is corrected. The correction coefficient set by the value setting processing unit 223 is applied. In this way, the traffic difficulty data calculated from the measurement data automatically measured by the information supply terminal 10 in the background processing is corrected by the precautions confirmed by the information provider with confidence, so that the data is more reliable. Can be.

After that, the passage difficulty level data calculation unit 222 notifies the user correspondence processing unit 221 of the end of the processing, and the user correspondence processing unit 221 returns the processing to the step S201. However, since the user correspondence processing unit 221 can operate in parallel with the processing of the passage difficulty data calculation unit 222, the notification of the end of processing from the passage difficulty data calculation unit 222 to the user correspondence processing unit 221 is not necessarily given. Not necessary.

(2-4) Barrier-free information provision The barrier-free information providing server 20 provides barrier-free information in response to a location data request from the map providing server 30 via the data transmission network NW.

FIG. 8D is a flowchart showing a processing procedure of the barrier-free information providing process executed by the barrier-free information providing unit 224 of the barrier-free information providing server 20.

The barrier-free information providing unit 224 first waits for the communication interface device 210 to receive the position data request from the map providing server 30 via the data transmission network NW (step S261).

Then, when it is determined that the location data request has been received from the map providing server 30, the barrier-free information providing unit 224 determines the target area mesh included in the location data request and the designated user category, and is difficult to pass. From the degree data storage unit 234, the passage difficulty level data of the provider category corresponding to the designated user category of the corresponding area mesh is read out (step S262). Here, since the target area mesh is used for the route search from the departure point to the destination point, a plurality of target area meshes are specified, and therefore, a plurality of passage difficulty data to be read are also required.

Next, the barrier-free information providing unit 224 extracts from the read-out plurality of passage difficulty data those having a passage difficulty equal to or higher than the threshold value (step S263). This threshold value may be a constant value regardless of the provider category, but it is desirable that the threshold value is different for each provider category. For example, since it is more difficult to pass in a wheelchair than on foot, the threshold value for the wheelchair provider category is set lower than the threshold value for the wheelchair provider category.

Then, the barrier-free information providing unit 224 transmits the position data (latitude / longitude of the area mesh) in the passage difficulty data extracted as the threshold value or more as the barrier-free information indicating the difficult passage position by the communication interface device 210. It is transmitted to the map providing server 30 via the network NW (step S264).

Further, the barrier-free information providing unit 224 can execute the charging process of the barrier-free information providing fee to the map providing server 30 (step S265). This is a process required when charging each time the status such as the amount of data and the number of times is provided, and may not be required when charging is performed based on another standard such as the number of days of use.

After that, the barrier-free information providing unit 224 returns the process to step S261.

FIG. 9 is a flowchart showing a processing procedure of route guidance processing executed by the map providing server 30. Here, it is assumed that the service user authentication process has already been completed by another process. Further, since the application for searching the store and guiding the route on the service user terminal 50 is a known application, the description thereof will be omitted.

The hardware processor 320A of the map providing server 30 acquires the user category, location, and preference of the service user (step S301). For example, the position and preference are acquired by the hardware processor 320A by receiving the position data and preference data transmitted from the service user terminal 50 via the data transmission network NW service by the communication interface device 310. be able to. Further, the user category of the service user can be acquired by the hardware processor 320A by reading the information of the corresponding service user stored in the user data storage unit 331.

Then, the hardware processor 320A proposes a recommended store to the service user based on the acquired user category, position, and preference (step S302). For example, the hardware processor 320A searches for a recommended store from the store data storage unit 332 based on the acquired user category, location data, and preference data, and data transmission of the recommended store information by the communication interface device 310. By transmitting data to the service-using user terminal 50 via the network NW, the data is displayed on the liquid crystal display 140 of the service-using user terminal 50. In addition, the hardware processor 320A can perform billing processing on the store proposed as the recommended store (step S303).

After that, the hardware processor 320A determines whether or not the communication interface device 310 has received the store determination information indicating that the store determination operation has been performed from the service user terminal 50 via the data transmission network NW service. (Step S304). If it is determined that the store determination information has not been received, the hardware processor 320A returns the process to step S302 and proposes another recommended store.

On the other hand, when it is determined that the store determination information has been received, the hardware processor 320A sets the position of the service user terminal 50 as the starting point and the determined store position as the destination (). Step S305). The location of the store can be obtained from the address of the store stored in the store data storage unit 332. Then, the hardware processor 320A selects an area mesh from the map data storage unit 333 based on the set points (step S306). This selection is performed, for example, by connecting the starting point and the target point with a straight line and selecting an area mesh within a range of several km on both sides of the straight line. Then, the hardware processor 320A transmits the position data request including the selected plurality of area meshes to the barrier-free information providing server 20 by the communication interface device 310 via the data transmission network NW service (step S307). As described above, the barrier-free information providing unit 224 of the barrier-free information providing server 20 assumes that the position data request is received in the above-mentioned step S261 of the barrier-free information providing process, and the difficult-to-pass position data extracted in the above-mentioned step S264. Will be returned as barrier-free information.

The hardware processor 320A acquires the returned difficult-to-pass position data (step S308). That is, the difficult-to-pass position data received by the communication interface device 310 is stored in a temporary storage area (not shown) of the storage device 330. Then, the hardware processor 320A calculates a route avoiding the difficult passage point based on the difficult passage position data, and stores the route data indicating the route in the route data storage unit 334 (step S309).

After that, the hardware processor 320A starts route guidance based on the route data stored in the route data storage unit 334. That is, the hardware processor 320A reads the map data near the user position, that is, the position of the service user terminal 50, from the map data storage unit 333, and uses the read map data among the route data stored in the route data storage unit 334. Guidance information is created by superimposing the route data of the corresponding portion on the map data (step S310). Then, the hardware processor 320A transmits this guidance information to the corresponding service user terminal 50 via the data transmission network NW by the communication interface device 310 (step S311). After that, the hardware processor 320A acquires the position of the service user terminal 50, that is, the user position (step S312) via the data transmission network NW by the communication interface device 310, and the service user sets it as the destination. It is determined whether or not the user has arrived at the recommended store (step S313). Here, if it is determined that the destination has not yet arrived, the hardware processor 320A returns the process to step S310 and creates updated guidance information corresponding to the user position.

In this way, when it is determined that the service user has arrived at the recommended store set as the destination, the hardware processor 320A can charge the store for the guidance fee (step S314).

In this way, by estimating the passage difficulty data for each provider category, it is possible to exclude the measurement data having different categories, and it is possible to estimate the passage difficulty data with high accuracy for each provider category.

Further, the information supply terminal 10 can transmit the caution information input by the information provider, the collected data storage unit 232 also accumulates the caution information, and the passage difficulty data calculation unit 222 estimates the passage difficulty. The degree data is corrected based on the caution information accumulated in the collected data storage unit 232. In this way, in addition to the measurement data passively collected, the caution information actively provided by the information provider is used, so that more accurate barrier-free information can be generated.

Further, the information supply terminal 10 can transmit caution information consisting of arbitrary character information, and the correction value setting processing unit 223 converts the character information into a correction coefficient. As a result, other than predetermined caution information can be used, and more accurate barrier-free information can be generated.

Further, the user correspondence processing unit 221 gives an additional point when the caution information is transmitted from the information supply terminal 10. Therefore, it is possible to give the information provider motivation to provide cautionary information.

Further, in the barrier-free route providing system according to one embodiment, a plurality of information supply terminals 10, a barrier-free information providing server 20 that communicates with each of the plurality of information supply terminals 10, and a user are provided. The service-using user terminal 50 and the map providing server 30 for transmitting guidance information to the service-using user terminal 50 are provided, and the barrier-free information providing server 20 has a plurality of passage difficulty data calculation units 222 and barrier-free information providing units 224. Based on the measurement data from the information supply terminal 10 of the above, the map providing server 30 generates barrier-free information according to the user category of the user of the service-using user terminal 50, and the map providing server 30 aims based on this barrier-free information. The route data is calculated according to the user category to the point, and the user is guided. Therefore, it is possible to provide route guidance corresponding to the difficulty of passage of the user.

Further, each of the information providers has a provider category corresponding to the user category, and the user correspondence processing unit 221 of the barrier-free information providing server 20 indicates the provider category of the information provider who provided the measurement data. The measurement data is accumulated in the data storage unit 232 in association with the information, and the passage difficulty data calculation unit 222 estimates the passage difficulty data for each user category based on the provider category, and the barrier-free information provision unit 224. Generates barrier-free information from the traffic difficulty data for each user category according to the user category. Therefore, barrier-free information can be easily calculated from the passage difficulty data according to the category of the user who needs route guidance.

Further, the service use user terminal 50 can include a traction force presenting device DD that presents a traction force that tractions the user in a direction to be moved according to the guidance information transmitted from the map providing server 30. Therefore, by using the traction force presenting device DD, it is possible to guide the route without visual perception.
