Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, it is rare for a user's movement to be carried out solely by an action such as walking, a private car, or public transportation, and it is carried out such that a plurality of actions are connected. Therefore, simply showing the total amount of decarbonization does not make it easy to understand which action contributes to decarbonization.

[0005] The present invention has been made in view of the above problems, and its main object is to provide a support system, a support method, and a program capable of relatively easily visualizing the decarbonization effects of a plurality of actions.

Means for Solving the Problems

[0006] To solve the above problems, a support system according to one aspect of the present invention includes: an acquisition unit that acquires location data of a terminal held by a user; a movement determination unit that determines the means of movement for each of a plurality of actions included in the movement history of the terminal based on the location data; an eco determination unit that determines whether each of the plurality of actions corresponds to a decarbonization action that contributes to reducing carbon dioxide emissions, and calculates a decarbonization amount representing the amount of reduction in carbon dioxide emissions for the action that corresponds to the decarbonization action; and a display unit that displays a display element representing the means of movement and the decarbonization amount for each of the plurality of actions on the terminal screen that displays the plurality of actions in a list.

[0007] Furthermore, another aspect of the present invention provides a support method which involves acquiring location data of a terminal owned by a user, determining the means of transportation for each of a plurality of actions included in the terminal's movement history based on the location data, determining whether each of the plurality of actions corresponds to a decarbonization action that contributes to reducing carbon dioxide emissions, calculating a decarbonization amount representing the amount of carbon dioxide emissions reduced for the action that corresponds to the decarbonization action, and displaying a display element representing the means of transportation and the decarbonization amount for each of the plurality of actions on the terminal screen which displays the plurality of actions in a list.

[0008] Furthermore, a program in another aspect of the present invention causes the computer of a terminal owned by the user to perform the following actions: acquire location data of the terminal, and, on the screen of the terminal which displays a list of multiple actions included in the terminal's movement history based on the location data, to display for each of the multiple actions a display element representing the means of transportation and a decarbonization amount representing the amount of carbon dioxide emissions reduced. [Effects of the Invention]

[0009] According to the present invention, it becomes possible to easily visualize and compare the decarbonization effects of multiple actions. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0011] Embodiments of the present invention will be described below with reference to the drawings. In this specification and in each drawing, elements similar to those described above in relation to previously shown drawings will be denoted by the same reference numerals, and detailed descriptions may be omitted as appropriate.

[0012] Figure 1 shows an example of a support system 100. The support system 100 comprises a support device 1 and a terminal 2 owned by a user UZ. The support device 1 and terminal 2 are connected to a communication network NT, such as the Internet, and can communicate with each other via the network. The support device 1 is a server. Terminal 2 is, for example, a smartphone or a tablet computer.

[0013] The support system 100 is a system designed to encourage behavioral change in users by easily visualizing the decarbonization effects of multiple actions included in the user's travel history, and by making users aware of which actions contribute to decarbonization.

[0014] The movement history of user UZ includes multiple actions such as movement on foot, movement by private car CR, or movement by train TR. These actions are carried out in combination like a string of beads.

[0015] For example, user UZ may use a private car CR to move from home to the nearest station, park there, and then transfer to public transportation such as train TR and move to a destination such as a workplace in the city center. Such a movement pattern is called "park and ride".

[0016] Public transportation includes, for example, trains, buses, or subways. A private car is an automobile other than a commercial vehicle that有偿 transports passengers or goods, specifically, an automobile used by the user himself for his own purposes, including a carless vehicle or a rental car.

[0017] A private car is not limited to a gasoline vehicle and may also be an eco-car. Eco-cars include, for example, electric vehicles, hybrid vehicles, plug-in hybrid vehicles, fuel cell vehicles, natural gas vehicles, hydrogen vehicles, or clean diesel vehicles.

[0018] Figure 2 is a block diagram showing a configuration example of the support device 1. The support device 1 is a computer including a processing unit 11, a storage unit 12, and a communication unit 13.

[0019] The processing unit 11 includes a CPU and executes information processing according to a program stored in the storage unit 12. The storage unit 12 includes a RAM, a ROM, and a non-volatile memory, etc. The communication unit 13 is an interface that connects the support device 1 to the communication network NT.

[0020] The program may be provided to the support device 1 via a non-temporary storage medium or may be provided to the support device 1 via a communication line.

[0021] Figure 3 is a block diagram showing an example configuration of terminal 2. Terminal 2, like support device 1, is a computer equipped with a processing unit 21, a storage unit 22, and a communication unit 23. Terminal 2 further includes a touch panel 24, a GNSS receiver 25, and an acceleration sensor 26.

[0022] The communication unit 23 includes a communication unit that implements a mobile communication or wireless LAN communication method for connecting terminal 2 to the communication network NT, as well as a communication unit that implements short-range wireless communication such as Bluetooth®.

[0023] The touch panel 24 integrates the display unit and the operation unit. The GNSS receiver 25 detects the position of the terminal 2 based on radio waves received from the GNSS (Global Navigation Satellite System).

[0024] Figure 4 is a block diagram showing an example of the functional configuration of terminal 2. The processing unit 21 of terminal 2 includes a location data acquisition unit 31, a step counting unit 32, a beacon receiving unit 33, an eco-car usage determination unit 34, a movement determination unit 35, an eco-determination unit 36, a data transmission / reception unit 37, and a display control unit 38. These functional units 31 to 38 are realized by the processing unit 21 executing information processing according to a program.

[0025] Furthermore, the processing unit 21 can access the location database 41, the BL (Bluetooth®) database 42, and the step count database 43. These databases 41 to 43 may be stored in the storage unit 22 or in an external storage device.

[0026] The location data acquisition unit 31 acquires location data of terminal 2 from the GNSS receiver 25 and registers it in the location database 41. The location database 41 stores the location of terminal 2 at each time point.

[0027] The step counting unit 32 calculates the user UZ's steps based on the vibration of the terminal 2 detected by the acceleration sensor 26 and registers it in the step count database 43. The step count database 43 stores the user UZ's step count history.

[0028] The beacon receiver 33 receives signals (hereinafter referred to as "beacons") transmitted from transmitters installed in public transportation and registers the time of beacon reception in the BL database 42. The BL database 42 stores the beacon reception history.

[0029] The transmitter periodically transmits a beacon containing device-specific ID information via short-range wireless communication such as Bluetooth®. The transmitter is installed, for example, inside a bus or at a subway ticket gate.

[0030] The eco-car usage determination unit 34 determines whether or not an eco-car is being used. The use of an eco-car is determined, for example, based on vehicle type data acquired from the in-vehicle device through an application program for vehicle-to-device communication (so-called V2D).

[0031] Furthermore, the eco-car usage determination unit 34 may, for example, associate the receipt of a Bluetooth® signal transmitted from an in-vehicle device of an eco-car with the fact that it is an eco-car, and then determine that the receipt of that signal constitutes the use of an eco-car. The reception history of signals from the in-vehicle device is also registered in the BL database 42.

[0032] The movement determination unit 35 calculates the movement history of terminal 2 based on the position of terminal 2 at each time point, which is stored in the position database 41. The movement history of terminal 2 includes multiple actions, which are distinguished according to the speed of movement. The movement determination unit 35 also calculates the distance traveled for each of these multiple actions.

[0033] The movement determination unit 35 then determines the mode of transportation for each of the multiple actions included in the movement history of terminal 2. At this time, the movement determination unit 35 determines actions using public transportation depending on whether or not a beacon is received, and determines actions using an eco-car depending on whether or not an eco-car is used.

[0034] For example, the movement determination unit 35 determines an action as "walking" if the average movement speed is less than a first threshold (e.g., 8 km / h) and there is a step count history during that period, and determines an action as "cycling" if the average movement speed is between the first threshold and the second threshold (e.g., 21 km / h). If the average movement speed is 0, it is determined to be "staying put".

[0035] Furthermore, the movement determination unit 35 identifies actions whose average movement speed is equal to or greater than the second threshold as either "automobile" or "train". Specifically, among actions whose average movement speed is equal to or greater than the second threshold, actions in which the movement path of terminal 2 overlaps with a railway line on the map data are identified as "train".

[0036] Among actions with an average travel speed of 2 or higher, actions other than "trains" are classified as "automobiles." In particular, actions that repeatedly receive beacons during the period, i.e., actions that continuously receive beacons from transmitters installed inside buses, are classified as "buses," while all other actions are classified as "private cars."

[0037] Furthermore, among actions identified as "private vehicle," those that have a history of using an eco-car during that period will be identified as "eco-car." In other words, "private vehicle" is distinguished into "private vehicle (non-eco-car)" and "eco-car."

[0038] In addition, the movement determination unit 35 determines that an action is "subway" if it includes a period during which the location of terminal 2 is unknown, from the time it receives a beacon from one transmitter to the time it receives a beacon from another transmitter, that is, from the time it receives a beacon at the ticket gate before boarding to the time it receives a beacon at the ticket gate after boarding.

[0039] The eco-determination unit 36 ​​determines whether each of the multiple actions for which the means of transportation has been identified corresponds to a decarbonization action, and calculates the amount of decarbonization for the actions that correspond to a decarbonization action. A decarbonization action is an action that contributes to the reduction of carbon dioxide emissions, and the amount of decarbonization represents the amount of reduction in carbon dioxide emissions.

[0040] Specifically, the eco-determination unit 36 ​​determines whether an action using "public transportation (train, bus, or subway)" or an action using an "eco-car" qualifies as a decarbonization action and calculates the amount of decarbonization. The amount of decarbonization is calculated by multiplying the distance traveled in the action by a conversion rate corresponding to the mode of transportation.

[0041] Furthermore, the eco-determination unit 36 ​​determines that actions using "walking" or "bicycle" where the straight-line distance from the starting point to the destination is greater than a predetermined amount (for example, 0.75 km or more) also qualify as decarbonization actions, and calculates the amount of carbon decarbonization.

[0042] On the other hand, the eco-determination unit 36 ​​determines that an action using a "private car (non-eco car)" does not qualify as a decarbonization action, and sets the amount of decarbonization to 0.

[0043] Furthermore, the eco-determination unit 36 ​​determines that actions using "walking" or "bicycle" where the straight-line distance from the starting point to the destination is less than a predetermined amount (for example, less than 0.75 km) do not qualify as decarbonization actions, and sets the amount of decarbonization to 0.

[0044] Furthermore, the eco-determination unit 36 ​​identifies certain actions, including decarbonization actions, that are performed in a specific order from among the multiple actions included in the movement history of terminal 2 as special decarbonization actions. For example, the eco-determination unit 36 ​​determines that an action using a private car and an action using public transportation are performed in a specific order, which qualifies as "park and ride".

[0045] When an action using a private car and an action using public transport are performed in this order, it corresponds to the outbound leg of a park-and-ride. On the other hand, when an action using public transport and an action using a private car are performed in this order, it corresponds to the return leg of a park-and-ride.

[0046] Actions using a private vehicle and actions using public transport may include walking, equivalent to the distance from the parking lot to the station. Furthermore, the requirement for distinguishing an action using a private vehicle from a pre-registered parking lot, or from an action using public transport from a pre-registered station, may be used to identify park-and-ride activities.

[0047] The eco-determination unit 36 ​​may calculate the amount of decarbonization using a special calculation method for a particular decarbonization action. For example, the amount of decarbonization may be calculated using a special calculation method prepared for park-and-ride, that is, a calculation method different from the usual calculation method that calculates the amount of decarbonization individually for each action.

[0048] The data transmission / reception unit 37 transmits history data representing the movement history of terminal 2 to the support device 1. The history data includes data for multiple actions, and the data for each action includes the distance traveled, the means of transportation, and the amount of carbon decarbonization. The data transmission / reception unit 37 also receives notifications of decarbonization points transmitted by the support device 1.

[0049] The display control unit 38 displays a movement history screen on terminal 2 to show a list of multiple actions included in terminal 2's movement history. A specific example of the movement history screen will be described in detail later.

[0050] The above describes an example of the functional configuration of terminal 2, but it is not limited to this, and some functional units, such as the movement determination unit 35 or the eco determination unit 36, may be implemented in the processing unit 11 of the support device 1.

[0051] Figure 5 is a block diagram showing an example of the functional configuration of the support device 1. The processing unit 11 of the support device 1 includes a history data acquisition unit 51, a movement history storage unit 52, a point registration unit 53, and a point notification unit 54. These functional units 51 to 54 are realized by the processing unit 11 executing information processing according to a program.

[0052] Furthermore, the processing unit 11 can access the movement history database 61 and the point database 62. These databases 61 and 62 may be stored in the storage unit 12 or in an external storage device.

[0053] The history data acquisition unit 51 acquires the history data transmitted by the terminal 2. The movement history storage unit 52 registers the acquired history data in the movement history database 61.

[0054] As shown in Figure 6, in the movement history database 61, the movement history of terminal 2 is divided into multiple actions, and each action is associated with the distance traveled, the means of transportation, and the amount of carbon decarbonization. The movement history of terminal 2 is created, for example, on a daily basis.

[0055] The movement history database 61 includes the fields "Action ID", "Location", "Time", "Distance Traveled", "Means of Transportation", "Decarbonization Action", "Combination", and "Decarbonization Amount".

[0056] "Action ID" is the identifier for the action. "Location" and "Time" represent the movement of terminal 2 during the action; that is, they represent the temporal change in the location of terminal 2 or the movement path of terminal 2. "Distance traveled" represents the distance traveled by terminal 2 during the action.

[0057] "Means of transportation" refers to the means of transportation identified for the action. Examples of means of transportation include walking, cycling, train, bus, subway, private car (non-eco-car), or eco-car. "Decarbonization action" indicates whether or not the action qualifies as a decarbonization action.

[0058] "Combination" indicates whether a particular decarbonization action, such as park-and-ride, is applicable. In other words, it indicates whether a specific set of actions, including a decarbonization action, were performed in a specific order. "Decarbonization Amount" represents the amount of carbon decarbonization achieved by the action.

[0059] The point registration unit 53 registers decarbonization points corresponding to the amount of decarbonization calculated for the movement history of terminal 2 in the point database 62, associating them with the user data of user UZ. The point notification unit 54 notifies terminal 2 of the registered decarbonization points.

[0060] Specifically, the point registration unit 53 converts the amount of decarbonization at a predetermined conversion rate to determine the decarbonization points. The amount of decarbonization and the decarbonization points are converted at a conversion rate of, for example, 1g:1 point. The point conversion rate is not limited to this and can be set as appropriate.

[0061] Furthermore, the point registration unit 53 may award special decarbonization points for special decarbonization actions such as park-and-ride. For example, more decarbonization points than usual may be awarded by changing the point conversion rate or adding additional points.

[0062] Figures 7 and 8 show examples of the movement history screen G displayed on terminal 2. The movement history screen G displays the movement history of terminal 2 on a daily basis. The movement history screen G includes a string TDC representing the total decarbonization amount for the selected date, and a list display field LST that displays a list of multiple actions included in the movement history.

[0063] The list display area LST shows a list of symbols SB and strings MN representing the means of transportation for each of the multiple actions. These symbols SB and strings MN are examples of display elements that represent means of transportation.

[0064] Multiple Symbol SBs are arranged in a single line in the order they were implemented. In the example shown, the Symbol SBs are arranged horizontally across the screen. The list display area LST is scrollable horizontally, allowing all Symbol SBs to be displayed by scrolling. Note that Symbol SBs may also be arranged vertically.

[0065] For actions that qualify as decarbonization actions among multiple actions, the symbol SC representing decarbonization actions will be displayed. The symbol SC representing decarbonization actions is added to, for example, the symbol SB representing transportation.

[0066] This is not limited to this example; the symbol SC representing decarbonization actions may be integrated with the symbol SB representing means of transportation. In other words, the symbol SB representing means of transportation itself may also represent decarbonization actions depending on how it is displayed.

[0067] For example, the symbol SB representing a means of transportation could be displayed in a color that represents decarbonization action (e.g., green), or, as shown in the eco-car symbol SB in Figure 8, the design of the symbol SB could be used to indicate that it is a decarbonization action.

[0068] In addition, the LST list display area shows the string KR representing the distance traveled and the string DC representing the amount of carbon decarbonization for each of the multiple actions. These strings KR and DC are displayed together with the symbols SB and MN representing the means of transportation.

[0069] The string "DC," which represents the amount of carbon decarbonization, is displayed for all actions. That is, the string "DC" representing the amount of carbon decarbonization is displayed not only for actions that qualify as carbon decarbonization actions, but also for actions that do not qualify as carbon decarbonization actions. The string "DC" displayed for actions that do not qualify as carbon decarbonization actions will contain characters such as 0 or a hyphen, indicating that the amount of carbon decarbonization is 0.

[0070] Furthermore, in the list display area LST, if a combination of multiple actions corresponds to a special decarbonization action such as park-and-ride, the string CBN indicating that it is a special decarbonization action and the string CDC indicating the amount of carbon decarbonization may be further displayed for those multiple actions.

[0071] In addition, the movement history screen G may also display decarbonization points notified by the support device 1.

[0072] As explained above, by visualizing and comparing multiple actions included in the movement history screen G displayed on terminal 2, along with their respective decarbonization amounts, users UZ can visually understand the impact of individual actions on decarbonization, thereby encouraging behavioral changes toward effective decarbonization actions.

[0073] Furthermore, by displaying the distance traveled along with the amount of carbon decarbonization for multiple actions, users (UZ) will be able to better understand the impact of individual actions on carbon decarbonization.

[0074] Furthermore, by displaying a message indicating when a combination of multiple actions constitutes a special decarbonization action such as park-and-ride, users (UZs) will be able to visually understand the impact of these special decarbonization actions on decarbonization.

[0075] Furthermore, by making the decarbonization points awarded to users (UZ) according to their decarbonization efforts exchangeable for rewards offered within communities such as local governments, it becomes possible to increase the motivation of users (UZ) to accumulate decarbonization points and further encourage behavioral change among them.

[0076] Figure 9 is a flowchart showing an example of the procedure for the support method implemented in the support system 100. The processing unit 11 of the support device 1 executes processes S11 to S14 shown in the right half of the figure according to the program. The processing unit 21 of the terminal 2 executes processes S21 to S26 shown in the left half of the figure according to the program.

[0077] First, terminal 2 calculates its movement history based on its position at each time point, which is stored in the location database 41 (S21, processing by the movement determination unit 35).

[0078] Next, terminal 2 determines the means of movement for each of the multiple actions included in the calculated movement history of terminal 2 (S22, processing as movement determination unit 35).

[0079] Next, terminal 2 calculates the amount of carbon decarbonization for the action that corresponds to the decarbonization action among the multiple actions (S23, processing as eco determination unit 36).

[0080] Next, terminal 2 transmits history data representing the movement history of terminal 2 to the support device 1 (S24, processing as data transmission / reception unit 37).

[0081] The calculation of movement history and transmission of history data (S21-S24) are performed, for example, each time the application program is launched, each time an individual action is completed, or at regular intervals such as every few hours or every day.

[0082] Subsequently, terminal 2 displays the movement history screen G (see Figure 7 or Figure 8) in response to user UZ's display request operation (S25, processing by the display control unit 38).

[0083] When history data is transmitted from terminal 2, the support device 1 acquires the history data transmitted by terminal 2 (S11, processing as history data acquisition unit 51).

[0084] Next, the support device 1 saves the acquired history data to the movement history database 61 (S12, processing as movement history storage unit 52).

[0085] Next, the support device 1 registers decarbonization points corresponding to the amount of decarbonization in the movement history of terminal 2 (S13, processing as point registration unit 53).

[0086] Next, the support device 1 notifies terminal 2 of the registered decarbonization points (S14, processing as point notification unit 54).

[0087] Registration and notification of decarbonization points (S13, S14) are performed, for example, when a point inquiry request is received from terminal 2, or at regular intervals such as every few hours or every day.

[0088] When support device 1 notifies terminal 2 of a decarbonization point, terminal 2 displays the decarbonization point notified by support device 1 on its screen (S26). This completes the series of steps in the support method.

[0089] Although embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and various modifications are of course possible for those skilled in the art.

[0090] In the above embodiment, "park and ride" was given as an example of a special decarbonization action (a set of specific actions performed in a specific order, including a decarbonization action). However, other actions such as "modal shift," which involves shifting freight transport from vehicles such as trucks to the use of rail or ship, which have a lower environmental impact, may also be identified as special decarbonization actions.

[0091] The following are some representative embodiments.

[0092] In a first embodiment, the support system includes: an acquisition unit that acquires location data of a terminal owned by the user; a movement determination unit that determines the means of movement for each of a plurality of actions included in the movement history of the terminal based on the location data; an eco determination unit that determines whether each of the plurality of actions is a decarbonization action that contributes to reducing carbon dioxide emissions, and calculates a decarbonization amount representing the amount of reduction in carbon dioxide emissions for the action that is a decarbonization action; and a display unit that displays a display element representing the means of movement and the decarbonization amount for each of the plurality of actions on the terminal screen that displays the plurality of actions in a list. This makes it possible to easily visualize and compare the decarbonization effects of multiple actions.

[0093] In a second embodiment, in the first embodiment, the movement determination unit may calculate the movement distance of each of the multiple actions, and the display unit may further display the movement distance for each of the multiple actions. This makes it easier to understand the relationship between the amount of carbon decarbonization of an action and the movement distance.

[0094] In a third embodiment, the system may further include a usage determination unit that determines whether or not an eco-car is being used, the movement determination unit may determine an action using the eco-car according to whether or not the eco-car is being used, and the eco-determination unit may determine that the action using the eco-car corresponds to the decarbonization action and calculate the amount of decarbonization. This makes it possible to visualize the amount of decarbonization from actions using eco-cars.

[0095] In a fourth embodiment, in the first embodiment, the terminal may include a receiving unit that receives signals transmitted from transmitters installed in public transportation, the movement discrimination unit may determine whether or not the signal has been received whether or not the action has been taken using public transportation, and the eco discrimination unit may determine that the action taking place using public transportation corresponds to the decarbonization action and calculate the amount of decarbonization. This makes it possible to visualize the amount of decarbonization achieved by actions taking place using public transportation.

[0096] In a fifth embodiment, in the first embodiment, the eco determination unit may determine that a specific set of actions, including the decarbonization action, are performed in a specific order from among the set of actions, and call them a specific decarbonization action. This makes it possible to visualize the amount of decarbonization achieved by the specific decarbonization action.

[0097] In a sixth embodiment, in the first embodiment, the eco-determination unit may determine that an action using a private vehicle and an action using public transportation constitute park-and-ride. This makes it possible to visualize the amount of carbon decarbonization achieved through park-and-ride.

[0098] In a seventh embodiment, in the fifth embodiment, the eco-determination unit may calculate the amount of decarbonization using a specific calculation method for the specific decarbonization action. This makes it possible to calculate the amount of decarbonization using a specific calculation method for the specific decarbonization action.

[0099] In the eighth aspect, the support method acquires location data of a terminal owned by the user, identifies the means of transportation for each of the multiple actions included in the terminal's movement history based on the location data, determines whether each of the multiple actions corresponds to a decarbonization action that contributes to reducing carbon dioxide emissions, calculates the amount of decarbonization representing the amount of carbon dioxide emissions reduced for the actions that correspond to the decarbonization action, and displays a display element representing the means of transportation and the amount of decarbonization for each of the multiple actions on the terminal screen that displays the multiple actions in a list. This makes it possible to easily visualize and compare the decarbonization effects of multiple actions.

[0100] In the ninth aspect, the program causes the computer of a terminal owned by the user to acquire location data of the terminal, and to display, on the terminal's screen which lists multiple actions included in the terminal's movement history based on the location data, a display element representing the means of transportation and a decarbonization amount representing the amount of carbon dioxide emissions reduced for each of the multiple actions. This makes it possible to easily visualize and compare the decarbonization effects of multiple actions. [Explanation of symbols]
