Description

[Technical field]

[0001] The present invention relates to a route information providing device, a route information providing system, a route information providing method, and a computer-readable medium. [Background technology]

[0002] 2. Description of the Related Art With the aim of ensuring smooth operation of transportation means such as trains and buses, technologies are being developed to effectively alleviate congestion in transportation facilities such as train stations.

[0003] For example, an information processing system (Patent Document 1) acquires congestion information for candidate stations extracted by a candidate station extraction means, and if the candidate station is congested, acquires an alternative route that uses an alternative station that can replace the congested candidate station.

[0004] The people flow guidance system (Patent Document 2) obtains the number of people that can board at each station from the line's operation status, calculates the number of people that cannot board at each station as the required waiting area, and distributes guidance information to guide people to the selected destination waiting area.

[0005] The route search tool (Patent Document 3) dynamically searches for route candidates when it receives search conditions including the departure station, destination station, and the allowable walking time that indicates the time the user can tolerate for walking. In this case, if an intermediate station is accessible on foot and the station-to-station travel time associated with the station is equal to or less than the allowable walking time, it is possible to search for route candidates including the walking section connecting the station and a nearby station. If the route candidates identified by the route search include a walking section, the walking section is clearly indicated and output on the map information around the station.

[0014] The present invention will be described below through the embodiments of the invention, but the invention according to the claims is not limited to the following embodiments. In addition, not all of the configurations described in the embodiments are necessarily essential as means for solving the problems. For clarity of explanation, the following description and drawings are omitted and simplified as appropriate. In each drawing, the same elements are given the same reference numerals, and duplicate explanations are omitted as necessary.

[0015] <Embodiment 1> Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a route information providing device 10 according to the first embodiment. The route information providing device 10 according to the present embodiment is communicably connected to a user terminal carried by a user. The route information providing device 10 presents routes to transportation facilities in the vicinity of the user's location to the user terminal. The route information providing device 10 mainly includes a user information acquiring unit 111, a route candidate acquiring unit 112, a congestion degree calculating unit 113, a route information generating unit 114, and an output unit 115.

[0016] The user information acquisition unit 111 acquires user information from a user terminal. The user information includes location information of the user terminal carried by the user. The user information may include an identifier of the user terminal and a signal indicating a request for route guidance. When the user information acquisition unit 111 acquires the user information, it supplies the acquired user information to the route candidate acquisition unit 112.

[0017] The route candidate acquisition unit 112 acquires information on one or more route candidates connecting the location of the user terminal and a boarding location of a means of transportation in the vicinity of the user terminal from the location information included in the user information. The boarding location of a means of transportation is, for example, a train station, a bus stop, or a taxi stand. The information on the route candidates includes a route connecting the location of the user terminal (current location) to the boarding location of the means of transportation, and an estimated time required to travel along the route at a predetermined speed. The predetermined speed is, for example, the walking speed of a typical human being. The predetermined speed may be set for each user terminal.

[0018] The route candidate acquisition unit 112 may have map information and a route search program. In this case, the route candidate acquisition unit 112 searches for boarding locations of transportation facilities located around the latitude and longitude of the user terminal, for example, and searches for a route to the boarding location using the map information.

[0019] The route candidate acquisition unit 112 may communicate with a route search device that exists outside the route information providing device 10 and acquire route candidates from the route search device. In this case, the route candidate acquisition unit 112 transmits position information of the user terminal to the route search device and requests route candidates. Then, when the route search device generates information on the route candidates, the route candidate acquisition unit 112 acquires the route candidates from the route search device.

[0020] When the route candidate acquisition unit 112 acquires route candidates by the above-mentioned method, the route candidate acquisition unit 112 supplies information on the acquired route candidates to the route information generation unit 114 .

[0021] The congestion degree calculation unit 113 uses the person data on the route candidate to calculate the congestion degree of the route candidate. The person data on the route candidate is acquired by a sensor installed on the route candidate. That is, the route information providing device 10 is communicably connected to the sensor installed on the route candidate. The person data on the route candidate is data for knowing the degree of congestion of people on a passageway such as a road or concourse that is a route candidate.

[0022] The person data is, for example, image data of a route candidate. When the person data includes image data, the congestion degree calculation unit 113 can calculate the congestion degree of the location where the image data was acquired by measuring the number of people included in the image data. The congestion degree calculation unit 113 may measure the distance between people from the image data, and calculate that the congestion degree of the location is relatively high when the distance between people is relatively small.

[0023] The person data may also indicate the number of mobile devices carried by each person on the route candidate. In this case, for example, the sensor acquires identifiers and location information transmitted by the mobile devices to generate data that can estimate the number of people on a given route candidate. In addition, the format, manner, and manner of the sensor that generates the person data are not limited to those described above.

[0024] The congestion degree calculated by the congestion degree calculation unit 113 is an index for relatively identifying the congestion state of people in a given location. For example, the congestion degree is indicated by a numerical value from 0 percent to 100 percent. In this case, a congestion degree of 0 percent indicates a state in which no people are detected in the location where the sensor is installed. A congestion degree of 100 percent indicates a state in which the density of people (e.g., the number of people per unit area) in the location where the sensor is installed exceeds a predetermined threshold. After calculating the congestion degree, the congestion degree calculation unit 113 supplies the calculated congestion degree to the route information generation unit 114.

[0025] The route information generating unit 114 generates route information from the congestion degree received from the congestion degree calculating unit 113 and information on the route candidates received from the route candidate acquiring unit 112. The route information includes information on a recommended route.

[0026] More specifically, for example, the route information generating unit 114 may select, as the recommended route, one of the multiple route candidates that has a low degree of congestion. Also, the route information generating unit 114 may select, as the recommended route, one of the multiple route candidates that takes a short time to reach the boarding location of the transportation means that is the destination. In this case, the route information generating unit 114 may correct the required time by taking into account the degree of congestion of the route candidate in relation to the estimated required time included in the information on the route candidate.

[0027] How the route information generating unit 114 selects a recommended route may be set in advance or may be set when generating the route information. The route information may include multiple recommended routes, and multiple recommended routes may be prioritized. The route information may also include information on route candidates that were not selected as recommended routes. After generating the route information, the route information generating unit 114 supplies the generated route information to the output unit 115.

[0028] The output unit 115 receives the route information from the route information generation unit 114 and outputs the received route information. More specifically, the output unit 115 transmits the route information to, for example, a user terminal that is communicatively connected.

[0029] Next, a route information providing method performed by the route information providing device 10 will be described with reference to Fig. 2. Fig. 2 is a flowchart showing the route information providing method according to the first embodiment. The flowchart shown in Fig. 2 is started by starting up the route information providing device 10, for example.

[0030] First, the user information acquisition unit 111 acquires user information including location information of a user terminal carried by a user (step S11).

[0031] Next, the route candidate acquisition unit 112 acquires one or more route candidates connecting the current position of the user terminal and boarding locations of transportation facilities in the vicinity of the user terminal based on the position information (step S12).

[0032] Next, the congestion degree calculation unit 113 acquires person data on people present on the route candidate from sensors installed on the route candidate (step S13).

[0033] The congestion degree calculation unit 113 calculates the degree of congestion of people on the route candidate from the acquired person data (step S14).

[0034] The route information generating unit 114 generates route information regarding a recommended route from the route candidates based on the congestion degree (step S15).

[0035] The output unit 115 outputs the route information (step S16). When the output unit 115 outputs the route information, the route information providing device 10 ends the series of processes.

[0036] The route information providing device and the information processing method according to the first embodiment have been described above. The route information providing device 10 has a processor and a storage device as components not shown. The storage device of the route information providing device 10 includes a storage device including a non-volatile memory such as a flash memory or an SSD (Solid State Drive). In this case, the storage device of the route information providing device 10 stores a computer program (hereinafter also simply referred to as a program) for executing the above-mentioned image processing method. The processor also reads the computer program from the storage device into a buffer memory such as a DRAM (Dynamic Random Access Memory) and executes the program.

[0037] Each of the components of the route information providing device 10 may be realized by dedicated hardware. In addition, a part or all of each component may be realized by a general-purpose or dedicated circuit, processor, or a combination of these. These may be configured by a single chip, or may be configured by multiple chips connected via a bus. A part or all of each component of each device may be realized by a combination of the above-mentioned circuits, etc. and a program. In addition, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an FPGA (field-programmable gate array), etc. can be used as a processor. The description of the configuration described here may also be applied to other devices or systems described below in this disclosure.

[0038] Furthermore, when some or all of the components of the route information providing device 10 are realized by a plurality of route information providing devices, circuits, etc., the plurality of route information providing devices, circuits, etc. may be centrally arranged or distributed. For example, the route information providing devices, circuits, etc. may be realized as a client-server system, a cloud computing system, etc., in a form in which each is connected via a communication network. Furthermore, the function of the route information providing device 10 may be provided in a SaaS (Software as a Service) format.

[0039] The above describes the embodiment 1. According to the embodiment 1, it is possible to provide a route information providing device and the like that can accurately determine a congestion degree with a simple configuration.

[0040] <Embodiment 2> Next, a description will be given of embodiment 2. Fig. 3 is a block diagram of a route information providing system according to embodiment 2. Fig. 3 shows a state in which a route information providing system 1, a camera 50, and a user terminal 400 are each communicatively connected to a network N1.

[0041] The route information providing system 1 includes a route information providing device 20 and a route search device 300. The route information providing system 1 according to this embodiment is communicably connected to a user terminal 400 carried by a user U and a plurality of cameras 50. The route information providing system 1 acquires user information from the user terminal 400 carried by the user U, and acquires image data from the camera 50. The route information providing system 1 presents to the user terminal 400 a route to a transportation facility in the vicinity of a location where the user U is located, based on the acquired user information and image data. The route information providing system 1 may include the camera 50.

[0042] The camera 50 captures the scenery of the place where the camera 50 is installed, generates image data, and supplies the generated image data to the route information providing system 1 via the network N1. The camera 50 includes an image sensor 51. That is, the camera 50 is one embodiment of a sensor installed on a route candidate so that the route information providing system 1 calculates the degree of congestion of people at the place where the camera 50 is installed. Each camera 50 has a unique identifier. When the camera 50 generates image data, the camera 50 supplies the image data to the route information providing system 1 in a manner that allows the identifier of each camera 50 to be identified. This allows the route information providing system 1 to link each camera 50 with the place where the camera is installed.

[0043] Next, the route information providing device 20 included in the route information providing system 1 will be described with reference to Fig. 4. Fig. 4 is a block diagram of the route information providing device 20 according to the second embodiment. The route information providing device 20 differs from the route information providing device 10 according to the first embodiment in that it includes an update unit 116 and a storage unit 120.

[0044] The update unit 116 causes the congestion degree calculation unit 113 to update the congestion degree of the route candidate in response to a predetermined request signal. The predetermined request signal may be, for example, a request signal received from the user terminal 400, or may be set as a predetermined interval (for example, 30 seconds, 60 seconds, or 90 seconds). When the update unit 116 receives the predetermined request signal, it supplies a signal to the congestion degree calculation unit 113 instructing it to update the congestion degree. When the congestion degree calculation unit 113 receives an instruction from the update unit 116, it acquires person data from a sensor installed on the route candidate, calculates the congestion degree, and supplies the calculated congestion degree to the route information generation unit 114. In this case, the route information generation unit 114 generates route information including the updated congestion degree and supplies the updated route information to the output unit 115. Furthermore, the output unit 115 outputs the updated route information. This allows the route information providing device 20 to suitably present the congestion degree of the route candidate to the user U.

[0045] The route candidate acquisition unit 112 in this embodiment is communicatively connected to the route search device 300, and acquires information about route candidates from the route search device 300. In this case, the route candidate acquisition unit 112 transmits position information of the user terminal to the route search device and requests route candidates. Then, when the route search device generates information about the route candidates, the route candidate acquisition unit 112 acquires the route candidates from the route search device.

[0046] The user information acquired by the user information acquisition unit 111 in this embodiment may include a time tolerance regarding the time required that the user is willing to accept. The time tolerance is an index regarding the time that the user is willing to accept until arriving at the boarding location of a specified means of transportation. In this case, the route information generation unit 114 generates route information by using the user information including the time tolerance in addition to the congestion degree.

[0047] The time tolerance may be a specific time such as 10 minutes, 30 minutes, etc. In this case, the route information generating unit 114 selects, as a recommended route, a route candidate that has an estimated required time shorter than the time specified as the time tolerance in addition to the congestion degree.

[0048] The time tolerance may be an abstract and relative identification symbol such as "hurry" or "slowly". For example, when the time tolerance is "hurry", the route information generating unit 114 selects a route candidate with a short estimated required time as a recommended route. On the other hand, when the time tolerance is "slow", the route information generating unit 114 extracts multiple route candidates in order from the route candidate with the shortest estimated required time, and selects a recommended route by taking into account the degree of congestion of the extracted multiple route candidates.

[0049] In addition, the user information acquired by the user information acquisition unit 111 in this embodiment may include priority information indicating either one of a required time priority and a congestion avoidance priority. In this case, the route information generation unit 114 generates route information by using the congestion degree and the priority information included in the user information.

[0050] In this case, when the route information generating unit 114 has acquired information indicating a priority on required time as the priority information, the route information generating unit 114 selects a route candidate with a relatively short required time as the recommended route. When the route information generating unit 114 has acquired information indicating a priority on avoiding congestion as the priority information, the route information generating unit 114 selects a route candidate with a relatively low degree of congestion as the recommended route.

[0051] The congestion degree calculation unit 113 in this embodiment acquires image data of a scene of a route candidate from the camera 50 as person data. The congestion degree calculation unit 113 may, for example, recognize a person image included in this image data, and calculate the congestion degree by counting the number of people present in the scene captured from the recognized person image. The congestion degree calculation unit 113 may also have a trained model trained to derive the congestion degree from this image data, and calculate the congestion degree by inputting the image data into this trained model. The congestion degree calculation unit 113 may also recognize a traffic area such as a road or concourse where people pass, and calculate the congestion degree from the number of people in this traffic area.

[0052] Furthermore, the congestion degree calculation unit 113 may use image data generated at multiple different times to measure the moving speed of people included in the image data, and use the measured moving speed to calculate the congestion degree. That is, for example, the congestion degree calculation unit 113 sets the congestion degree when the moving speed of people in an image containing a certain number of people X1 is relatively fast to a lower congestion degree than the congestion degree when the moving speed of people in an image containing the same number of people X1 is relatively slow. On the other hand, the congestion degree calculation unit 113 sets the congestion degree when the moving speed of people is relatively slow to a higher congestion degree than the congestion degree when the moving speed is relatively fast.

[0053] The congestion degree calculation unit 113 may also measure the distance between people (person-to-person distance) included in the image data and calculate the congestion degree using the measured person-to-person distance. For example, the congestion degree calculation unit 113 measures the distance between people who are closest to each other and calculates the average of these. The congestion degree calculation unit 113 then uses the calculated average value of the person-to-person distance when calculating the congestion degree. For example, when the average value of the person-to-person distance in an image in which a certain number of people X1 exists is relatively small, people exist more densely than when the average value of the person-to-person distance in an image in which the number of people X1 exists is relatively large. Therefore, in this case, the congestion degree calculation unit 113 sets the congestion degree when the person-to-person distance is relatively small to be higher than the congestion degree when the person-to-person distance is relatively large.

[0054] The route information generated by the route information generating unit 114 in this embodiment includes route congestion degree information regarding the congestion degree of multiple route candidates including the recommended route. This allows the route information providing device 20 to appropriately present the surrounding congestion situation to the user U. Furthermore, the user U who uses the route information providing system 1 can receive information regarding multiple route candidates including the recommended route and actively select a route. This allows the route information providing device 20 to provide highly convenient route information.

[0055] The route information generated by the route information generating unit 114 may include superimposed image data in which map information related to route candidates and information related to the congestion degree of the route are superimposed. This allows the route information providing device 20 to provide route information that is easy to recognize. In other words, the user U can visually recognize information on the user terminal 400 in which the user's location, boarding locations of nearby transportation facilities, and route candidates including the congestion degree are superimposed on a map.

[0056] Next, an example of the process performed by the congestion degree calculation unit 113 will be described with reference to FIG. 5. FIG. 5 is a diagram showing an example of the process performed by the congestion degree calculation unit 113 according to the second embodiment. The diagram shows a data group input to the congestion degree calculation unit 113 and a data group output by the congestion degree calculation unit 113. In the example shown in FIG. 5, the congestion degree calculation unit 113 accepts, as an input data group, image data generated by the camera 50, position information linked to the camera 50, and the time when the camera 50 captured the image related to the image data. That is, the input data group is person data. The congestion degree calculation unit 113 outputs the congestion degree, position information, and time from these input data groups as an output data group. The congestion degree calculation unit 113 supplies the output data group to the route information generation unit 114.

[0057] In the example shown in Fig. 5, the congestion degree calculation unit 113 acquires image data supplied from the camera 50 as person data, but the person data is not limited to this. For example, the person data acquired by the congestion degree calculation unit 113 may include position data of a mobile device carried by a person on the route candidate. In this case, a sensor installed on the route candidate receives position information and a unique identifier transmitted by a mobile device present in the vicinity of the sensor. As a result, the congestion degree calculation unit 113 estimates the number of people present in the vicinity of the sensor, their moving speeds, and the like, and calculates the congestion degree.

[0058] The person data acquired by the congestion degree calculation unit 113 may include measurement data of temperature or humidity on the route candidate. In this case, a sensor installed on the route candidate measures the temperature or humidity on the route where the person passes, and acquires the temperature or humidity in the surrounding area of ​​the route. In this way, the congestion degree calculation unit 113 measures whether the temperature or humidity on the route has risen higher than the surrounding temperature or humidity, and calculates the congestion degree from the temperature difference or humidity difference.

[0059] The person data acquired by the congestion degree calculation unit 113 may include voice data of voices uttered by people on the route candidate. In this case, a sensor installed on the route candidate collects voice data such as speech uttered by people passing through the passage and footsteps when walking. As a result, the congestion degree calculation unit 113 calculates the congestion degree by measuring the volume of the voices on the passage.

[0060] Furthermore, the person data acquired by the congestion degree calculation unit 113 may include data on the number and frequency of postings of specific text information related to the congestion degree among text information posted on a social network service (SNS) or a predetermined website. The person data may include a plurality of the above-mentioned data.

[0061] Next, the route search device 300 will be described with reference to Fig. 6. Fig. 6 is a block diagram of the route search device 300 according to the second embodiment. The route search device 300 uses user information of the user terminal 400 to search for a route connecting the user terminal 400 and a boarding location of a transportation facility in the vicinity thereof to generate route candidates, and supplies information on the generated route candidates to the route information providing device 20. The route search device 300 may be a personal computer, a server, a calculation processing device for route search, or the like. The route search device 300 mainly includes a communication unit 311, a route search unit 312, a control unit 313, and a storage unit 320.

[0062] The communication unit 311 is an interface for communication between the route search device 300 and the route information providing device 20. For example, the communication unit 311 receives position information of the user terminal 400 from the route information providing device 20 via the network N1. The communication unit 311 also transmits information related to the generated route candidates to the route information providing device 20 via the network N1.

[0063] The route search unit 312 searches for one or more routes from the location information of the user terminal 400 to a boarding location of a means of transportation in the vicinity of the user terminal 400, and generates information on route candidates.

[0064] The control unit 313 includes a calculation device such as a CPU, and controls each component of the route search device 300. The control unit 414 reads a program from the storage unit 420, and realizes a predetermined function according to this embodiment in accordance with the read program.

[0065] The storage unit 320 is a storage device including a non-volatile memory, and stores at least a program for causing the route search device 300 to realize the functions of this embodiment and map information.

[0066] Next, the user terminal 400 will be described with reference to Fig. 7. Fig. 7 is a block diagram of the user terminal 400 according to the second embodiment. The user terminal 400 may be a mobile phone, a smartphone, a tablet terminal, or the like. The user terminal 400 has a display unit 411, a position information generating unit 412, a communication unit 413, a control unit 414, and a storage unit 420 as main components.

[0067] The display unit 411 is a display device including, for example, a liquid crystal panel or an organic electroluminescence panel, and displays predetermined information in a manner that is visible to the user. The display unit 411 displays, for example, route information that the route information providing system 1 outputs to the user terminal 400.

[0068] The position information generating unit 412 generates information relating to the position of the user terminal 400. For example, the position information generating unit 412 may obtain position information from a global navigation satellite system (GNSS).

[0069] The communication unit 413 is an interface for communication between the user terminal 400 and the route information providing system 1. For example, the communication unit 413 transmits position information of the user terminal 400, an identifier of the user terminal 400, and the like to the route information providing system 1 via the network N1. Also, for example, the communication unit 413 receives route information output by the route information providing system 1.

[0070] The control unit 414 includes a calculation device such as a CPU, and controls each component of the user terminal 400. The control unit 414 reads a program from the storage unit 420, and realizes a predetermined function according to this embodiment in accordance with the read program.

[0071] The storage unit 420 is a storage device including a non-volatile memory, and stores at least a program for realizing the functions of the present embodiment in the user terminal 400. Such a program may include, for example, an application program for the user terminal 400 to display route information.

[0072] Next, the process performed by the route information providing system 1 will be described with reference to a specific example. Fig. 8 is a diagram showing a specific example of the process performed by the route search device. Fig. 8 shows a map of the surrounding area where a user U is located. The user U is located near a building A10. The building A10 is a place where many people gather, such as a concert hall or a stadium. After the event is over, the user U plans to use nearby public transportation to return home from here.

[0073] A first railway line C10 and a second railway line C20 are shown in the vicinity of the user U. The first railway line C10 includes a first station B10. The second railway line C20 includes a second station B20. The first railway line C10 and the second railway line C20 merge at a third station B30 and continue beyond that point. Of the above-mentioned stations, the stations relatively close to the location of the user U are the first station B1 and the second station B20.

[0074] A first route R10 and a second route R20 exist as routes connecting the location of the user U to the first station B20. A third route R30 and a fourth route R40 exist as routes connecting the location of the user U to the second station B20. A plurality of cameras 50 are installed on the first route R10, the second route R20, the third route R30, and the fourth route R40.

[0075] In such a situation, the user U uses the route information providing system 1 by using the user terminal 400. The user U performs an operation to request the route information providing system 1 to provide guidance on a route to a boarding location for nearby transportation facilities.

[0076] Fig. 9 is a first diagram showing an example of route information. Fig. 9 shows a first image P11 displayed on the display device of the user terminal 400. The image P11 shows an icon U10 representing the user U, a building A10, a first station B10, and a second station B20 superimposed on a map of the surrounding area of ​​the location where the user U is present.

[0077] The first image P11 also displays a button labeled "Travel time" and a button labeled "Avoid congestion" along with messages such as "Searching for routes to nearby stations" and "Which would you like to prioritize?" When searching for a route, the user U selects one of the above-mentioned buttons. The route information providing system 1 generates route information that prioritizes travel time or avoiding congestion, depending on the user U's selection.

[0078] Fig. 10 is a second diagram showing an example of route information. Fig. 10 shows a second image P12 displayed on the display device of the user terminal 400. The second image P12 shows a state in which the route information providing system 1 generates route information and the user terminal 400 displays the route information after the user U selects "avoid congestion" in the first image P11 shown in Fig. 9.

[0079] 10, the first route R10, the second route R20, and the third route R30 are indicated by dotted lines, and the fourth route R40 is indicated by a thick solid line. In addition, in each route candidate, a circular symbol with a different diameter is attached to the location where the camera 50 is installed. In addition, the second image P12 displays messages such as "Route found" and "Route candidates and recommended route are displayed."

[0080] In the above situation, the circular symbols shown in the second image P12 indicate the degree of congestion at each location where the camera 50 is installed. In this example, the diameter of the circle is associated with the degree of congestion. That is, the larger the diameter of the circular symbol, the higher the degree of congestion at that location. According to the second screen P12, the diameter of the circular symbol attached to the fourth route R40 is smaller than that of the other route candidates. That is, the fourth route R40 has a lower degree of congestion than the other route candidates. Therefore, the route information providing system 1 selects the fourth route R40 as a recommended route and displays it by a solid line.

[0081] FIG. 11 is a third diagram showing an example of route information. FIG. 11 shows a third image P13 displayed by the display device of the user terminal 400. The third image P13 shows a state in which the user U who has seen the second image P12 shown in FIG. 10 has selected the fourth route R40 and is proceeding. In FIG. 11, an icon U10 representing the user U is located in the middle of the fourth route R40. The route connecting the icon U10 and the second station B20 is shown by a thick solid line. Also, route candidates not selected by the user U are shown by a thick white line. Also, the third image P13 displays a message saying "The latest congestion status is displayed."

[0082] In Fig. 11, the congestion degree at the location where the camera 50 is installed has changed from the second image P12 shown in Fig. 10. That is, in the route information providing system 1, the update unit 116 of the route information providing device 20 generates a signal to update the congestion degree, for example, every 30 seconds. In response to this, the route information generating unit 114 generates route information including the updated congestion degree. This route information also includes the congestion degree of route candidates not selected by the user U. With this configuration, the route information providing system 1 generates information according to the change in the situation and presents it to the user U. Therefore, the user U can use the route guidance while recognizing the updated information.

[0083] The embodiment has been described above. Note that the route information providing system 1 according to the embodiment is not limited to the above-mentioned configuration. For example, in the route information providing system 1, the user information acquiring unit 111 may further acquire information regarding the destination to which the user is heading. In this case, the route candidate acquiring unit 112 acquires, as route candidates, routes to the destination by the user using transportation. In this case, for example, the user U requests route guidance for a route to a destination such as a home or an office. In response to this, the route information providing system 1 provides guidance on a route to the destination via transportation.

[0084] The above has described the embodiment 2. According to the route information providing system 1 or the route information providing device 20 according to the embodiment 2, it is possible to provide a route information providing device, a route information providing method, and a program for efficiently using transportation facilities.
