[0003] [Patent Document 1] JP 2001-280992 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, even if a pedestrian route could be obtained, there were problems with the conventional method, such as the following: For example, when a user who is not confident in his or her physical strength tries to walk in an unfamiliar place, it is difficult for the user to know whether the route is walkable given his or her physical strength and physical condition. The present invention has been made in consideration of the above-mentioned problems, and has an object to provide a technique that enables a user to easily recognize the travel load amount of a route obtained by the user through a search. [Means for solving the problem]

[0005] In order to achieve the above object, the travel load guidance system includes a searched route acquisition unit that acquires a searched route searched by a user, a first travel load acquisition unit that acquires a first travel load amount which is a travel load amount when traveling along the searched route, a past route acquisition unit that acquires a past route traveled by the user in the past, a second travel load acquisition unit that acquires a second travel load amount which is a travel load amount of the past route, and a comparison unit that compares the first travel load amount with the second travel load amount and informs the user of the comparison result.

[0006] That is, the travel load guidance system acquires the travel load (first travel load) of a route (searched route) obtained by a user through a search, and further acquires the travel load (second travel load) of a route (past route) traveled by the user in the past. Then, the system informs the user of a comparison result between the first travel load and the second travel load. Therefore, the user can easily recognize the travel load of the route obtained by the search by referring to the comparison result. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Here, the embodiments of the present invention will be described in the following order. (1) Overall configuration: (1-1) User terminal configuration: (1-2) Configuration of the moving load information system: (2) Transport load information processing: (3) Other embodiments:

[0009] (1) Overall configuration: 1 is a block diagram showing the overall configuration including a travel load guidance system 10 according to the present invention. In this embodiment, the travel load guidance system 10 has a function of comparing the travel load when traveling on foot along a searched route searched by a user with the travel load of a previous route that the user actually traveled on foot in the past, and providing guidance thereon. The user terminal 100 is a terminal used by a user who uses this function to input instructions and view processing results.

[0010] (1-1) User terminal configuration: The user terminal 100 is a terminal operated by a user of the travel load information system 10, and in this embodiment, is a portable terminal such as a smartphone or a tablet. The user terminal 100 includes a communication unit 140, a GNSS receiving unit 141, a UI unit 142, and a control unit 120. The communication unit 140 includes a circuit for communicating with other devices. The user terminal 100 can communicate with the travel load information system 10 via the communication unit 140.

[0011] The GNSS receiver 141 is a device that receives signals of the Global Navigation Satellite System. The GNSS receiver 141 receives radio waves from navigation satellites and outputs signals for calculating the position of the user terminal 100. The control unit 120 acquires the signals and acquires the position of the user terminal 100.

[0012] The UI unit 142 is an interface unit for receiving instructions from a user and providing various information to the user, and includes a touch panel display, switches, a speaker, a microphone, etc. The control unit 120 includes a CPU, RAM, and ROM, and can execute various programs recorded on a recording medium or in the ROM. In this embodiment, the control unit 120 periodically identifies the current location and time based on the output of the GNSS receiving unit 141. The control unit 120 associates the history of the current location and time with a user ID, and transmits them to the travel load information system 10 at a predetermined timing.

[0013] The control unit 120 also causes the display of the UI unit 142 to display a screen for route search, accepts the destination and departure point input by the user, and transmits them to the travel load guidance system 10. At least one of the departure point and destination may be the current location of the user terminal 100 (if the departure point and destination are the same, input of a stopover point is accepted). The control unit 120 also causes the display of the UI unit 142 to display information indicating the searched route returned from the travel load guidance system 10 and the comparison result of the travel load amount.

[0014] (1-2) Configuration of the moving load information system: The travel load information system 10 includes a control unit 20 having a CPU, RAM, ROM, etc., a recording medium 30, and a communication unit 40, and the control unit 20 can execute a program stored in the recording medium 30 or the ROM. In this embodiment, a travel load information program 21 can be executed as this program. The communication unit 40 includes a circuit for communicating with other devices, and the travel load information system 10 can communicate with a user terminal 100 via the communication unit 40.

[0015] Map information 30a and movement history 30b are recorded in the recording medium 30. In this embodiment, the map information 30a is for pedestrians. The map information 30a includes node data indicating the positions of nodes set on roads on which pedestrians pass, shape interpolation point data indicating the positions of shape interpolation points for identifying the shapes of roads between nodes, link data indicating connections between nodes, facility data indicating the positions of facilities on roads and in their surroundings, and the like.

[0016] The positions of nodes and shape interpolation points include altitude in addition to latitude and longitude. Link data also includes information indicating the link and gradient. Furthermore, if a step is included in the link, information indicating the position of the step is included in the link data. Furthermore, if a staircase is included in the link, the positions of both end points of the staircase (latitude, longitude, altitude) are included, and the horizontal distance, vertical distance, and gradient of the staircase can be obtained from the positions of both end points. A step refers to a deviation in the road surface in the height direction, and a staircase refers to a state in which multiple steps are consecutive.

[0017] The travel history 30b is a history of the position and time of the user terminal 100 of the user indicated by the user ID, which is recorded in association with the user ID. The travel history 30b is updated as needed during the operation of the travel load information system 10. From the history of the position and time of the user terminal 100, a stay point (including the user's home) where the user stayed for a predetermined time or more, a link where the user traveled by a means of travel other than walking, and a link where the user traveled on foot are identified. If the travel speed indicates walking, it can be identified that the history is one where the user traveled on foot, and the control unit 20 acquires the past route by connecting the links indicated by the history of travel by walking in chronological order. In addition, the control unit 20 regards the start point of travel by walking as the departure point, and the end point as the destination. Alternatively, if the user traveled on a route obtained by route search in the past and arrived at the destination of the route, the control unit 20 regards the destination as the destination of the route, and regards the start point of travel after route search as the departure point.

[0018] The control unit 20 executes a travel load amount guidance program 21 to realize a function of comparing the travel load amount of a searched route searched by a user with the travel load amount of a past route and providing guidance. By executing the travel load amount guidance program 21, the control unit 20 functions as a searched route acquisition unit 21a, a first travel load amount acquisition unit 21b, a past route acquisition unit 21c, a second travel load amount acquisition unit 21d, and a comparison unit 21e.

[0019] By the function of the searched route acquisition unit 21a, the control unit 20 acquires the searched route searched by the user. That is, when the control unit 20 receives the starting point and the destination from the user terminal 100, it searches for a pedestrian route from the starting point to the destination and acquires the searched route.

[0020] Using the function of the first movement load amount acquisition unit 21b, the control unit 20 acquires a first movement load amount, which is a movement load amount when moving along the searched route. In this embodiment, the movement load amount is represented by the route length of the searched route, the distance of a section with a gradient equal to or greater than a predetermined gradient value, and the presence or absence of stairs.

[0021] Using the function of the first travel load acquisition unit 21b, the control unit 20 refers to the map information 30a and identifies the route length of the searched route, the distance of the gradient section with a gradient value equal to or greater than the default gradient value included in the searched route, and the presence or absence of stairs. Specifically, the control unit 20 calculates the total length of the searched route as the total length of the searched route. The link length is acquired based on the positions of the nodes at both ends of the link. The control unit 20 also identifies gradient sections with a gradient value equal to or greater than the default gradient value (for example, an absolute value of 5 degrees in this embodiment) in the searched route and calculates the total distance of the gradient sections. The control unit 20 also determines the presence or absence of stairs for each link that constitutes the searched route, and if stairs exist, acquires their position (for example, the position of the midpoint between the start point and the end point of the stairs). In this embodiment, the control unit 20 is configured to determine the presence or absence of stairs with an absolute value of a gradient value equal to or greater than a predetermined value, which is identified from the horizontal distance and vertical distance of the stair section.

[0022] By the function of the past route acquisition unit 21c, the control unit 20 acquires the past route that the user has traveled in the past. That is, in this embodiment, the control unit 20 acquires the past route of the user who requested the route search based on the travel history 30b corresponding to the user ID of the user, and if there is a past route (condition 1) whose destination matches the destination of the current search route and a past route (condition 2) whose route length matches the search route by a predetermined ratio (for example, 50%) or more, it is considered that the user can estimate the travel load from his / her past travel experience, and in this embodiment, the travel load is not compared with the past route. In this embodiment, if there is no past route that satisfies both conditions 1 and 2, the past route (whose match rate is less than a predetermined ratio or whose destination is different) is set as the target for acquiring the travel load. In this way, when a route whose destination is a point that the user has never set as a destination in the past or a route whose match rate with the past route is less than a predetermined ratio is obtained as a result of the search, the user can be informed of the comparison result with the past route and made aware of it.

[0023] By the function of the second movement load amount acquiring unit 21d, the control unit 20 acquires the second movement load amount, which is the movement load amount of the past route. That is, the control unit 20 acquires the route length, the distance of the gradient section with a gradient value equal to or greater than the predetermined gradient value, and the presence or absence of stairs for each past route that is the target of acquisition of the second movement load amount by the past route acquiring unit 21c. The specific processing contents are the same as the processing contents in the first movement load amount acquiring unit 21b.

[0024] By the function of the comparison unit 21e, the control unit 20 compares the first movement load amount with the second movement load amount and informs the user of the comparison result. That is, the control unit 20 extracts a past route having a second movement load amount similar to the first movement load amount, and informs the user of the past route. With respect to the route length, the control unit 20 extracts a past route having a second movement load amount equivalent to a preset ratio of the first movement load amount. More specifically, assuming that the route length of the search route is L1, the route length of the past route is L2, and the preset ratio is a, the control unit 20 extracts a past route such that L1×a≒L2. Although a may be a value greater than 0 (for example, 0.5, 1, 1.5, 2, 3, etc.), in this embodiment, the explanation will be continued assuming that a is an integer greater than or equal to 1, assuming that the user can easily imagine. That is, when there is a past route whose route length is similar to an integer multiple of the search route, the control unit 20 compares the route length of the past route with that of the search route, and informs the user of the comparison result. In this embodiment, if there is a previous route with a similar route length (i.e., L1 ≒ L2 (in this case a = 1)), guidance is provided indicating the difference in route length (corresponding to the difference between the first and second travel load amounts), and if there is a previous route with a route length similar to an integer multiple a (L1 × a ≒ L2 (in this case a = an integer greater than or equal to 2)), guidance is provided indicating the value a.

[0025] In this embodiment, the control unit 20 compares the section lengths of gradient sections with gradients equal to or greater than a preset gradient value for gradient sections, and compares the presence or absence (number) of stairs for gradient sections. The control unit 20 then provides guidance indicating the difference in gradient section lengths (corresponding to the difference between the first travel load amount and the second travel load amount) and the presence or absence of stairs. The control unit 20 generates such display data and returns it to the user terminal 100. The user terminal 100 displays it on the display of the UI unit 142 based on the display data transmitted from the travel load amount guidance system 10.

[0026] In this way, by guiding a past route having a second travel load amount equivalent to a preset ratio of the first travel load amount, the user can recognize a past route having a second travel load amount equivalent to a preset ratio of the first travel load amount, and it is possible to easily imagine the travel load amount of the currently searched route. Also, by providing guidance showing the difference in travel load amount from the past route, the user can recognize the difference in travel load amount from the past route, and it is possible to easily imagine the travel load amount of the currently searched route.

[0027] As described above, the travel load information system 10 of the present embodiment informs the user of the comparison result between the travel load (first travel load) of a route (searched route) obtained by the user through a search and the travel load (second travel load) of a route (past route) traveled by the user in the past. Therefore, the travel load information system 10 can make it easier for the user to recognize the travel load of a route (searched route) newly obtained by the user through a search by referring to the comparison result.

[0028] (2) Transport load information processing: Next, the travel load guidance process executed by the control unit 20 will be described with reference to Fig. 2. The travel load guidance process is executed when a route search request is received from the user terminal 100 along with the departure point and destination. When the travel load guidance process is started, the control unit 20 searches for a route using the function of the searched route acquisition unit 21a (step S100). That is, the control unit 20 searches for a pedestrian route from the departure point to the destination and acquires the searched route.

[0029] Next, the past route acquisition unit 21c determines whether the searched route includes a past movement history (step S105). In this embodiment, when there is a past route that satisfies both the above-mentioned conditions 1 and 2, the control unit 20 determines that the searched route includes a past movement history.

[0030] If it is not determined in step S105 that the past routes of the user are included, the control unit 20 performs the process of steps S110 to S125 for all past routes of the user. First, the control unit 20 performs a comparison process based on route length (step S110). FIG. 3A is a flowchart of the comparison process based on route length. In the comparison process based on route length, the control unit 20 acquires a searched route using the function of the first travel load amount acquisition unit 21b (step S200), and acquires the route length of the searched route (step S205). That is, the control unit 20 acquires information indicating the searched route obtained by the search in step S100 of FIG. 2, and acquires the route length of the searched route based on the link lengths of the links constituting the searched route, the position of the starting point, and the position of the destination.

[0031] Next, the control unit 20 uses the function of the past route acquisition unit 21c to determine whether or not there is a past route whose route length is similar to that of the search route (step S210). That is, the control unit 20 acquires the route length for each past route, and determines whether or not there is a past route whose route length is within a range of ±5% of the route length of the search route multiplied by a (here, a=1).

[0032] If it is determined in step S210 that the searched route exists, the control unit 20 acquires the comparison result based on the distance with the corresponding past route using the function of the comparison unit 21e (step S215). That is, the control unit 20 acquires the difference between the route length of the searched route and the route length of a past route similar to the route length of the searched route, and the past route as the comparison result. Note that, if there are multiple past routes that serve as the basis for Y determination in step S210, all of them may be acquired as the guidance target for the user, or the past route with the closest route length may be acquired as the guidance target, or the most recent past route may be acquired as the guidance target.

[0033] If it is determined in step S210 that there is no such route, the control unit 20 determines whether or not there is a past route whose route length corresponds to a preset ratio of the searched route by using the function of the past route acquisition unit 21c (step S220). That is, the control unit 20 determines whether or not there is a past route whose route length is within a range of ±5% of a value equivalent to a times the route length of the searched route (here, a is an integer of 2 or more).

[0034] If it is determined in step S220 that the past route exists, the control unit 20 executes step S215. If step S220 is determined to be Y and step S215 is executed, the control unit 20 acquires the corresponding past route and "a times" as a comparison result. If it is not determined in step S220 that the past route exists, the control unit 20 considers the past route to be incomparable.

[0035] After completing the comparison process based on the route length in FIG. 3A, the control unit 20 performs a comparison process based on gradient sections (FIG. 2, step S115). FIG. 3B is a flowchart of the comparison process based on gradient sections. In the comparison process based on gradient sections, the control unit 20 acquires information indicating the searched route by using the function of the first travel load acquisition unit 21b (step S300), and acquires the section lengths of gradient sections included in the searched route that have a gradient value equal to or greater than a preset gradient value (for example, an absolute value of 5 degrees in this embodiment) (step S305). That is, the control unit 20 refers to the map information 30a and acquires gradient information of each link of the searched route. Note that in this embodiment, the description will continue assuming that uphill and downhill are not distinguished. The control unit 20 identifies gradient sections with a gradient value equal to or greater than the preset gradient value in the searched route, and calculates the total value of the section lengths of the gradient sections.

[0036] Next, the control unit 20 acquires the section lengths of sections with gradients equal to or greater than the default gradient value included in the past route using the function of the first travel load acquisition unit 21b (step S310). That is, the control unit 20 performs a process of acquiring gradient information for each link of the past route for each past route. The control unit 20 identifies sections with gradients equal to or greater than the default gradient value on the past route and performs a process of calculating the total value of the gradient sections for each past route.

[0037] Next, the control unit 20 determines whether or not there is a previous route whose gradient section length is similar to the gradient section length of the searched route (step S315). Specifically, it is determined whether or not there is a previous route whose gradient section length is within a range of ± a preset value (e.g., 5%) of the gradient section length of the searched route acquired in step S305.

[0038] If it is determined in step S315 that there is a past route with a similar gradient section length, the control unit 20 acquires the corresponding past route and the comparison result based on the gradient section length by the function of the comparison unit 21e (step S320). That is, the control unit 20 acquires a past route having a gradient section length similar to the gradient section length of the search route and the difference in gradient section length between both routes. If there are multiple corresponding past routes, the control unit 20 may acquire all of them, may acquire the past route with the smallest difference in gradient section length, or may acquire the most recent past route. If it is not determined in step S315 that there is a similar past route, the control unit 20 considers them incomparable (step S325).

[0039] Returning to FIG. 2, the control unit 20 then acquires the location of stairs on the searched route using the function of the first travel load amount acquisition unit 21b (step S120). That is, the control unit 20 determines whether or not there are stairs for each link constituting the searched route, and acquires the location of stairs (for example, the midpoint between the fulcrum and the end point of the stairs) if there are stairs. Next, the control unit 20 acquires the location of stairs on the past route to be compared using the function of the second travel load amount acquisition unit 21d (step S125). In this embodiment, the past route to be compared is the past route acquired in step S215 of FIG. 3A and / or step S320 of FIG. 3B. The control unit 20 also acquires the location of stairs on the past route to be compared in the same manner as in step S120.

[0040] After step S125 is completed, or if step S105 is judged as Y, the control unit 20 uses the function of the comparison unit 21e to generate display data for outputting the results, and returns the data to the user terminal 100 (step S130). The user terminal 100 that has received the display data displays a guide showing the searched route and its travel load on the display of the UI unit 142, based on the display data.

[0041] Fig. 4 is a diagram showing an example of guidance in the user terminal 100. In the guidance example of Fig. 4, the searched route and its travel load (first travel load) are displayed in an area 301, and a past route acquired as a comparison target based on route length and gradient section length and its travel load (second travel load) are displayed in an area 302. In the example of Fig. 4, an example is shown in which the past route to be compared in the comparison based on route length and the past route to be compared in the comparison based on gradient section length are the same, but of course, different past routes may be acquired for both. In the case where they are different, a past route similar (to be compared) in terms of route length and a past route similar (to be compared) in terms of gradient section length are separately guided.

[0042] In the example of guidance in FIG. 4, the difference between the route length of the searched route and the route length of the past route is clearly indicated, but it is also possible to simply present the route length of the searched route and the route length of the past route (the user can recognize the difference between the two from the difference between the two values). Also, as shown in the example of FIG. 4, the route length (walking distance) of the searched route may be converted into the number of steps or walking time and displayed, and the difference between the number of steps or walking time of the past route may be presented. In FIG. 4, the line showing the route indicates the degree of gradient by the gradation of density. The darker the color, the steeper the gradient. Bar 303 indicates the correspondence relationship between the degree of gradient of the slope and the density of the gradation. Also, at the point where there are stairs, a speech bubble indicating the position of the stairs is displayed. The user can grasp the position and number of stairs from this display. If stairs are not displayed, the user can recognize that there are no stairs on the route. Regarding the gradient, as shown in FIG. 5, the gradient transition of both routes may be illustrated, and the ratio of the section length with a gradient equal to or greater than a predetermined gradient value to the total length of the route may be presented.

[0043] It should be noted that if the determination in step S105 is YES, or if step S225 or step S325 is executed, the control unit 20 provides guidance on the searched route in response to the route search request, and does not present the comparison result with the past route.

[0044] (3) Other embodiments: The above embodiment is an example for implementing the present invention, and various other embodiments can be adopted. For example, a user terminal for collecting a user's movement history and a user terminal for making a route search request and viewing the results may be the same or different. If they are different, when the terminal for making the route search request and viewing the results is different from the user terminal for collecting the movement history, the former is not limited to being a portable terminal.

[0045] The travel load information system may be a device realized by a plurality of devices (for example, a client and a server, or a plurality of servers). At least some of the searched route acquisition unit 21a, the first travel load acquisition unit 21b, the past route acquisition unit 21c, the second travel load acquisition unit 21d, and the comparison unit 21e constituting the travel load information system may be present separately in a plurality of devices. For example, the search function of the searched route acquisition unit 21a may be performed by a different route search server. Also, for example, the function of accumulating the travel history of the past route acquisition unit 21c may be performed by a different travel history accumulation server. Also, the travel load information system may be realized as a standalone in a user terminal. Some of the configurations of the above-mentioned embodiments may be omitted, and the order of processing may be changed or omitted.

[0046] The searched route acquisition unit may be capable of searching not only routes for walking, but also routes for wheelchairs and electric carts. In the latter case, the searched route acquisition unit may be configured to search for a route without stairs or steps. In the case of a wheelchair, the searched route acquisition unit may be configured to search for a route with a gradient less than a predetermined gradient value.

[0047] In the past route acquisition unit, past routes to be compared with the searched route may simply be past routes whose matching rate with the searched route (the proportion of matching sections in the route length of the searched route) is less than a predetermined ratio.

[0048] The travel load may include the ratio of sections with gradients equal to or greater than a preset gradient value to the entire route (slope inclusion ratio). The gradient value may be divided into a plurality of levels, and the ratio of sections of each level to the entire route may be obtained. Specifically, for example, the gradient may be divided into five levels from 0 to 4, with level 0 being flat and level 4 being the steepest, and the gradient sections of level 4 may be counted as A%, level 3 being B%, and so on, and the inclusion ratio in both the searched route and the past route may be compared for each level.

[0049] The travel load may include not only the presence or absence of stairs, but also the number of stairs and the gradient of the stairs. Also, the travel load may be divided into a plurality of levels for the number of stairs and the gradient of the stairs, and the user may be informed of which level of stairs is included in the route. Also, in the above embodiment, the presence or absence of stairs is compared, but the presence or absence of steps may be compared, and the comparison result may be informed.

[0050] As for the gradient, as in the above embodiment, a comparison may be made between gradient sections with a gradient value equal to or greater than a preset gradient value without distinguishing between uphill and downhill, or a comparison may be made between uphill and downhill sections. Uphill and downhill sections are distinguished based on the traveling direction of the route. When distinguishing between uphill and downhill, only uphill sections may be compared, or a comparison may be made between uphill sections and downhill sections. Similarly, for stairs and steps, only stairs and steps in the upward direction may be compared, or a comparison may be made between stairs and steps in the upward direction and steps in the downward direction.

[0051] The travel load amount in the case where the comparison unit is configured to guide a past route having a second travel load amount equivalent to a predetermined ratio of the first travel load amount is not limited to the route length. For example, the comparison unit may be configured to guide a past route having a gradient section length that is a times (a is greater than 0) the gradient section length of a predetermined gradient value or more in the searched route, together with the fact that it is a times. Alternatively, the comparison unit may be configured to guide a past route having a number of steps of stairs in the searched route that is a times (a is greater than 0) the number of steps of stairs included in the past route.

[0052] In the above embodiment, the comparison process based on the route length in Fig. 3A and the comparison process based on the gradient section in Fig. 3B are configured to be performed independently of each other, but the two may be performed in association with each other. For example, if it is determined in step S210 of the comparison process based on the route length in Fig. 3A that there is a previous route whose route length is similar to that of the search route, the comparison process based on the gradient section in Fig. 3B may be performed on that previous route.

[0053] Furthermore, the technique of the present invention can also be applied as a program or method. The above-mentioned system, program, and method may be realized as a single device or may be realized by using parts shared with each part provided in the vehicle, and include various aspects.
