Embodiments according to the present invention will be specifically described below with reference to the drawings.
(First embodiment)
FIG. 1 is a block diagram showing a schematic configuration of an information processing system 100 according to the first embodiment of the present invention. The information processing system 100 includes a terminal device 1 and a server 2.

  The terminal device 1 is used by a user, and is an electronic device such as a mobile phone, a smartphone, a tablet, or a notebook computer. At least a part of the terminal device 1 and the server 2 is realized by a computer. The terminal device 1 communicates with the server 2 via the network 3.

  The terminal device 1 includes a communication unit 11, an operation input unit 12, an output unit 13, a position positioning unit 14, and a control unit 15.

  The communication unit 11 is an interface that transmits and receives information between the control unit 15 and the server 2 via the network 3.

  The operation input unit 12 is an interface for a user to input an operation to the terminal device 1, and is, for example, a touch panel or a microphone in a mobile electronic device, or a keyboard or a touch pad in a notebook computer.

  The output unit 13 is an interface that outputs various information from the terminal device 1 to the user, and is, for example, a liquid crystal display that displays video. Specifically, the output unit 13 displays a GUI (Graphical User Interface) for receiving an operation from the user, route information to be described later, and the like. Alternatively, the output unit 13 may be a speaker that outputs sound.

  Further, the output unit 13 may not directly present information to the user. For example, the output unit 13 may be an interface that outputs a video signal and / or an audio signal to an externally connected display unit and / or audio reproduction unit, or outputs data to an externally connected printing device. It may be an interface that outputs data to the terminal device 1 or an external storage device (not shown). Hereinafter, the description will be continued assuming that the output unit 13 is a display.

  The position positioning unit 14 measures the position of the terminal device 1. The position positioning unit 14 may include, for example, a GPS (Global Positioning System) receiver (not shown), and may position the position based on the received GPS satellite signal. In addition to the GPS positioning, the position positioning unit 14 performs base station positioning based on received radio wave intensity from a communicating base station, Wi-Fi positioning based on a Wi-Fi (registered trademark) access point, and the like. You may measure the position of. Alternatively, positioning may be performed by a plurality of methods, and the one having the highest accuracy among them may be selectively used.

  The position of the terminal device 1 can be expressed by latitude and longitude. While the user is using the terminal device 1, the position of the terminal device 1 substantially matches the position of the user. However, the position positioning unit 14 may not be able to accurately measure the position of the terminal device 1, and the current position obtained by positioning may include some errors.

  The control unit 15 includes a search condition setting unit 151, an information transmission unit 152, and an information reception unit 153. Each of these units may be a function obtained by a processor (not shown) in the terminal device 1 executing a predetermined program.

  The search condition setting unit 151 sets search conditions. The search condition setting unit 151 can set a search condition by receiving conditions such as information regarding a departure place, a destination, and time from the user via the operation input unit 12. Alternatively, the search condition setting unit 151 may set at least a part of the search conditions from other than user input. For example, the position of the terminal device 1 measured by the position positioning unit 14 is set as the departure place, or the current time is set as the departure time. Or you may. The search condition may include more detailed conditions such as whether to use an elevator or an escalator for movement.

  The information transmission unit 152 transmits information such as search conditions to the server 2 via the communication unit 11 and the network 3.

  The information receiving unit 153 receives information such as route information from the server 2 via the network 3 and the communication unit 11.

  On the other hand, the server 2 includes a communication unit 21, a storage unit 22, and a control unit 23.

  The communication unit 21 is an interface that transmits and receives information between the control unit 23 and the terminal device 1 via the network 3.

  The storage unit 22 is a fixed storage such as a hard disk, and stores a route network information database 221, a timetable information database 222, and a station premises information database 223. Information in each database can be used by the control unit 23.

  The route network information database 221 includes, for example, map information and traffic network information as route network information.

  The map information includes map data such as road maps of the whole country and each region, and map object information associated with the map data. The map data is a map representing an actual road. The map object information includes shape information about the shape of the facility displayed on the map, note information about the note displayed on the map, symbol information about the symbol displayed on the map, and the like.

  The traffic network information is information that defines a traffic network and a road network.

  The information of the transportation network includes route information of the transportation facility, fee information, and the like. Hereinafter, an example in which the transportation is a train will be mainly described. However, the present embodiment can be applied to other transportation such as a bus, an airplane, and a ship.

  The information on the road network is expressed by a combination of node data that is a node on the road network expression such as an intersection and link data that is a road section between nodes. The node is specified by latitude and longitude, for example, and corresponds to the position of the detailed map.

  The timetable information database 222 includes information about the timetable of the transportation facility included in the traffic network information as timetable information. For example, the timetable information indicates the departure time of each station for a train included in the traffic network information.

  The station premises information database 223 includes information about stations included in the traffic network information as station premises information.

  The station premises information includes information regarding facilities in the station premises for each station. Facility information, a facility name, and facility location information are associated with station facility information. Examples of facilities in the station include ticket gates, shops, toilets, stairs, elevators, escalators, waiting rooms, smoking areas, restaurants, rest rooms, shops, vending machines, benches, roofs, and electric bulletin boards.

  The station premises information includes information on the passage network within the station premises. The information on this passage network is also expressed by a combination of nodes and links. Nodes can be set at both ends of the link, as well as in the above facilities where people pass. In addition to the passage itself, the link includes a link connecting the stair node on the platform and the stair node on the floor to which the stair goes. Further, the links include those connecting the elevator node on the home and the elevator node on the elevator destination floor, and those connecting the escalator node on the home and the elevator node on the escalator destination floor. You may go out.

  Furthermore, the relationship between each facility and the stop position of the train may be associated with the station premises information. As a specific example, a staircase at a certain position on the platform is associated with a vehicle nearest to the staircase. Here, information such as the route, the direction (up and down, XX line), and the vehicle number is included for the nearest vehicle. The vehicle number may be an absolute number such as “No. 4 car” or a relative number such as “fourth car from the front”. Moreover, it replaces with the nearest vehicle and the door of the nearest vehicle may be linked | related. In addition, the positional relationship between the elevator or the escalator and the stop position of the train may be associated.

  For convenience of explanation, it is called “station”, but if the transportation facility is a ship, the station premises information may be information on the port premises, and if the transportation facility is an aircraft, the station premises information May be information on the airport premises.

  Here, at least a part of each database in the storage unit 22 may be stored in an external device connected to the server 2 via the network 3.

  The control unit 23 includes an information reception unit 231, a movement information acquisition unit 232, a position specification unit 233, a movement time estimation unit 234, a route search unit 235, and an information transmission unit 236. Each of these units may be a function obtained when a processor (not shown) in the server 2 executes a predetermined program.

  The information receiving unit 231 receives information such as search conditions from the terminal device 1 via the network 3 and the communication unit 21. The information receiving unit 231 receives route network information, timetable information, and station premises information from the storage unit 22. Each received information is used by the control unit 23.

  The movement information acquisition unit 232 acquires movement information from the departure place to the destination. The movement information is information indicating a “path” for how to move from the departure place to the destination. In the present embodiment, it is assumed that at least a part of the vehicle travels using a transportation facility (hereinafter, a train will be described). However, the movement information does not have to include a specific time such as when to use a train that departs from a certain station.

  The movement information acquisition unit 232 may acquire predetermined movement information such as from home to work location. Alternatively, the movement information acquisition unit 232 may acquire the movement information by performing a route search using the route network information and the station premises information as necessary based on the departure place and the destination included in the search conditions. . When a route search within a station premises is performed, station premises information is used. An average search may be performed during route search to obtain an average time required for movement.

  The position specifying unit 233 predicts and specifies the position where the user gets on the transportation and / or the position where the user gets off from the transportation included in the movement information, and generates position information indicating the specified position. When the transportation is a train, the former is called a boarding position and the latter is called a getting-off position. The boarding position and the getting-off position may be rough such as “frontward” and “rearward” of the train, may be a vehicle unit such as “car 3”, “fourth from the front”, or “one of car 3” It may be finer than a door unit such as “eye door”.

  Various methods for specifying the position are conceivable. As an example, a vehicle that stops at a position close to a predetermined facility such as a ticket gate or an elevator may be specified as a boarding position or a getting-off position based on station premises information. Alternatively, the user may specify the boarding position or the getting-off position. Moreover, when there is a transfer, it may be specified based on a combination of a route before transfer and a route after transfer. A more specific example will be described later.

  The travel time estimation unit 234 estimates travel time from the transportation facility to a predetermined location based on the position information. This predetermined location is preferably on the “path” to the destination. In this case, at least a part of the travel time from the position of getting off the transportation to the destination is estimated. The travel time estimation unit 234 can estimate the travel time by searching for a route from the transportation facility to a predetermined location.

  As a specific example, the travel time may be the transfer time required for the travel from the getting-off platform (home of the route before transfer) to the transfer home (home of the route after transfer) in transfer. The transfer time varies depending on where you get off at the platform (for example, ahead or behind). In addition, when the station or transportation changes due to transfer (transfer from a train to a bus, etc.), the travel time may be the transfer time required for travel from the getting-off place to the boarding place. As another example, the travel time may be the time required to travel from the position of getting off to the station exit or the ticket gate.

  The route search unit 235 considers the estimated travel time, searches for a route that travels from the departure point to the destination using at least a part of the above transportation, and generates route information. In route search, route network information, timetable information, and station premises information can be used as necessary. Unlike the movement information indicating the “route”, the route information includes specific times such as when to use a train that departs from a certain station at what hour and how many minutes to arrive at a destination.

  The information transmission unit 236 transmits the generated route information to the terminal device 1 from the communication unit 21 via the network 3.

  FIG. 2 is a sequence diagram illustrating an example of a processing operation of the information processing system 100 in FIG. First, the search condition setting unit 151 of the terminal device 1 sets a search condition. The search condition is transmitted to the server 2 by the information transmission unit 152 (step S1).

  In response to this, the information receiving unit 231 of the server 2 receives the search condition (step S11). Then, the movement information acquisition unit 232 performs a route search based on the search condition, and acquires movement information indicating a “path” from the departure point to the destination (step S12).

  FIG. 3 is a diagram schematically illustrating an example of movement information. In the figure, it is assumed that the user U1 requests a route search from the departure point O1 to the destination D, and the user U2 performs a route search from the departure point O2 to the destination D. It is assumed that the nearest stations of departure points O1 and O2 are both A stations. However, the ticket gate g1 of the A station is close to the departure point O1, and the ticket gate g2 of the A station is close to the departure point O2. Such a thing is grasped from the route network information and the station premises information.

  In this case, the travel information for the user U1 goes from the departure point O1 to the ticket gate g1, walks from the A station to the B station on the P line, changes to the Q line train at the B station, and goes to the C station. Going, getting off at station C, going to destination D on foot from station C. On the other hand, the movement information for the user U2 goes on foot from the departure point O2 to the ticket gate g2, and thereafter, the movement information is the same as the movement information for the user U1.

  In this way, the movement information indicates a route such as what kind of place should be routed and which transportation means should be used.

  Returning to FIG. 2, the position specifying unit 233 specifies the boarding position and / or the getting-off position of the train included in the movement information (step S13). Thereby, position information indicating the specified position is generated.

  FIG. 4 is a diagram for explaining an example of the position specifying method, and corresponds to FIG. As shown in FIG. 4, according to the station premises information, it is assumed that the ticket gate g1 is close to the stop position of the fourth car of the P-line train at the station A. Further, it is assumed that the ticket gate g2 is close to the stop position of the first car of the P-line train.

  In the movement information, the user U1 enters the station A platform from the ticket gate g1. The ticket gate g1 is close to the stop position of the fourth car, and the user is likely to get on the fourth car. Therefore, the position specifying unit 233 specifies the boarding position of the user U1's P-line train as “No. 4 car”. As another example, the position specifying unit 233 may specify the boarding position as “behind the train” or “door behind the fourth car”.

  On the other hand, in the movement information, the user U2 enters the platform of the A station from the ticket gate g2. The ticket gate g2 is close to the stop position of the first car, and the user is likely to get on the first car. Therefore, the position specifying unit 233 specifies the boarding position of the user U2's P-line train as “No. 1 car”. As another example, the position specifying unit 233 may specify the boarding position as “front of the train” or “door in front of the first car”.

  Returning to FIG. 2, the travel time estimation unit 234 estimates the travel time after getting off the transportation facility in consideration of the position information (step S <b> 14).

  FIG. 5 is a diagram for explaining an example of the travel time estimation method, and corresponds to FIG. As shown in FIG. 5, according to the station premises information, the stairs ST1 is in the vicinity of the stop position of the fourth car of the train in the platform of the P-line B station (FIG. 5 (a)). This staircase ST1 is connected to the platform staircase ST2 of the Q line B station. On the platform of the Q-line B station (FIG. 5B), the staircase ST2 is near the stop position of the fourth car on the train. Therefore, the user who comes from the stairs ST2 is likely to get on the fourth train of the Q line train.

  In the position information, since the boarding position of the user U1 is the fourth car, it is considered that the user U1 gets off from the fourth car as it is at the B station. As shown to Fig.5 (a), it is near from the 4th car to staircase ST1. Considering this, it is estimated that the travel time required for the user U1 to change from the P-line train to the Q-line train at station B is relatively short 3 minutes.

  On the other hand, in the position information, since the boarding position of the user U2 is the first car, it is considered that the user gets off from the first car at the B station as it is. As shown in FIG. 5 (a), it is far from the first car to the staircase ST1. Considering this, it is estimated that the travel time required for the user U2 to change from the P-line train to the Q-line train at station B is a relatively long 10 minutes.

  Such a specific travel time may be calculated by the travel time estimation unit 234 performing a route search using the station premises information. Or you may memorize | store in the station premises information database 223 beforehand the movement time with respect to each of the alighting position in P line B station. Also, the traveling time required for transfer may be longer during morning and evening rush hours.

  FIG. 5 shows an example in which the transfer route has only one route that passes through stairs ST1 and ST2. On the other hand, when there are a plurality of transfer routes, the travel time estimation unit 234 may employ the longest travel time among the multiple travel times estimated for each transfer route, or the shortest travel time. May be adopted.

  As shown in FIG. 5B, since the users U1 and U2 are likely to get on the fourth car of the Q line train, the position specifying unit 233 specifies the boarding position of the Q line as "No. 4 car". May be. Then, the travel time estimation unit 234 may further estimate the travel time required to get off the No. 4 car on the Q line and travel to the exit of the C station (or the destination D).

  Returning to FIG. 2, the route search unit 235 searches for the optimum route from the departure point to the destination according to the estimated travel time (step S15). Thereby, route information indicating the route obtained by the search is generated.

  FIG. 6 is a diagram illustrating an example of route information, and corresponds to FIG. The departure time is assumed to be 10:00 for both users U1 and U2.

  FIG. 6A shows the following route information of the user U1. Depart from O1 at 10 o'clock, walk to station A, and pass through ticket gate g1 to arrive at the platform at 10:15. Then, take the P-line train (No. 4 car) that departs from station A at 10:20 and get off at station B at 10:40. Here, according to FIG. 5, since the travel time required for the transfer at the station B of the user U1 is 3 minutes, the train rides on the Q-line train leaving the station B at 10:45. Eventually, it will arrive at destination D at 10:55. When the travel time estimation unit 234 estimates the travel time after getting off the train on the Q line, route information considering this can be generated.

  FIG. 6B shows the route information of the user U2 as follows. Depart from O2 at 10 o'clock, walk to station A, and pass through ticket gate g2 to arrive at the platform at 10:15. Then, take the P-line train (No. 1 car) that departs from station A at 10:20 and get off at station B at 10:40. This getting-off time is the same as the getting-off time in the route information of the user U1.

  Here, according to FIG. 5, the travel time required for the transfer at the station B of the user U2 is 10 minutes. Therefore, the user U2 cannot get on the train of the Q line which leaves B station at 10:45. So, at 10:55, take the Q-line train that departs from station B. Eventually, it will arrive at destination D at 11:05.

  As can be seen from a comparison of FIGS. 6A and 6B, the users U1 and U2 have the same getting-off time at the P-line B station, but the travel times required for the transfer are different. In the present embodiment, the route search unit 235 searches for a route in consideration of the travel time required for this transfer. As a result, route information that is different between the users U1 and U2, that is, route information optimal for the users U1 and U2 is generated.

  Returning to FIG. 2, the generated route information is transmitted to the terminal device 1 by the information transmitting unit 236 (step S16). In response to this, the information receiving unit 153 of the terminal device 1 receives the route information. Then, the route information is output from the output unit 13 (step S2).

  In addition, when a plurality of transportation facilities are included in the movement information, in step S13, the position specifying unit 233 preferably specifies the boarding position and / or the getting-off position for all of them. In step S14, it is desirable that the movement time estimation unit 234 estimates the movement time for each of the specified positions. Further, in step S15, the route search unit 235 preferably performs route search in consideration of all travel times.

Furthermore, the movement information may be a part of the route from the starting point to the destination, not the entire route. For example, the movement information may be a route in a combination of the transportation before the transfer and the transportation after the transfer, a combination of the platform and the ticket gate, and a combination of the platform and the exit of the station.
Then, while the route search unit 235 searches for a route, that is, while spreading the route search from the departure place to the destination, the travel time is estimated for the above combination, and the estimated travel time is taken into consideration. (For example, as a node cost at a transfer station node), subsequent route search diffusion may be continued.

  Moreover, although the example which specifies a boarding position and estimates movement time was shown, you may specify a getting-off position and estimate movement time. The getting-off position may be directly specified by some method. As described above, the getting-off position may be specified as the getting-off position on the assumption that the getting-off position is as it is from the getting-on position.

  That is, in order to estimate the travel time required to transfer from the P-line train (train before transfer) to the Q-line train (train after transfer) shown in FIG. What is necessary is just to specify at least one position among a position, the boarding position of a Q line train, and the alighting position.

  As described above, in the first embodiment, the route search is performed in consideration of the position to get on the transportation facility and the position to get off the transportation facility. Therefore, it is possible to estimate the travel time such as transfer time more accurately and generate appropriate route information.

Hereinafter, some examples of methods for specifying the boarding position or the getting-off position by the position specifying unit 233 will be described.
As a first example, the position specifying unit 233 can use the station premise information to specify the position based on the position of the facility in the station premise or the structure of the station.

  For example, FIG. 4 shows an example in which a vehicle that stops near the ticket gate is specified as the boarding position. In addition, a stairway connected to the platform, an elevator, an escalator, and a vehicle that stops near the transfer gate may be used as the boarding position. In particular, if the search conditions are set to “use” an elevator or escalator, the vehicle that stops near the elevator or escalator is set as the boarding position, and “not used” is set. It is effective to use a vehicle that stops near the stairs as the boarding position.

  When there are a plurality of ticket gates or the like, the boarding position may be specified based on the boarding probability for each boarding position determined in advance. The boarding probability can be determined according to the size of the ticket gate (number of automatic ticket gates, etc.).

  Moreover, about a staircase and an escalator, you may consider not only a position but direction. For example, if the staircase is between the stop position of car 1 and the stop position of car 2 and the lead of the stairs faces the stop position side of car 1, car 1 may be the boarding position. it can. Further, if the passage from the stairs to the stop position of the third car is wide but the passage to the stop position of the fourth car is narrow, the third car can be set as the boarding position.

  As a second example, the position specifying unit 233 can specify a position based on an input from a user. For this purpose, the position set by the user via the operation input unit 12 may be included in the search condition. In this case, it is convenient that the operation input unit 12 is a touch panel arranged on the display.

  FIG. 7 is a diagram illustrating an example of a screen for accepting an input of a boarding position from a user. This screen is displayed on the output unit 13 by the search condition setting unit 151 when the search condition is set.

  In the center of the displayed screen, there is a schematic display 51a showing an outline of the station to be used (the nearest station of departure, the transfer (via) station, the nearest station of the destination, the nearest station from the current position, etc.). Be placed. The outline display 51a includes a mark 51b that imitates a azimuth magnet so that east, west, north, and south can be grasped. You may show how many stories a station is and what floor of a station is displayed on the schematic display 51a (code | symbol 51c). In the case of the figure, reference numeral 51c indicates that the station has a first basement floor (B1F), a first floor (1F), a second floor (2F), and a rooftop, and the current first basement floor (B1F) is indicated on the schematic display 51a by diagonal lines. It has been shown.

  The outline display 51a of the station schematically or faithfully shows the structures such as the platform 51d and the track 51e. Furthermore, facilities on the home such as the stairs 51f may be displayed. It is desirable for the display to be able to grasp the location of the facility within the station. Moreover, you may specify that the stairs 51f leads to the 1st floor (1F). In addition, you may display other facilities, such as an elevator and an escalator.

  If the outline of the station does not fit in the outline display 51a, an icon 51g for scrolling the screen may be displayed. In the figure, when the user touches the icon 51g, the north of the station is displayed.

  On the displayed screen, a station route 52a is arranged above the station outline display 51a. The route 52a indicates a schematic route from the entrance / exit 52b of the station to the platform 52c of the route of the transportation facility to be used (a route designated by the user). The schematic display 52a in the figure is that there is a ticket gate 52d at a position 10m from the A4 entrance 52b of the station, a down stairway 52e at a position 10m from the ticket gate 52d, and an eighth platform 52c at a position 6m from the staircase 52e. Is shown.

  A drum roll 53a for setting the boarding position is arranged at the bottom of the displayed screen. This figure shows a state in which “5th from front” is selected. By rotating the drum roll 53a by flicking or the like, another car can be selected. Further, a recommended car (recommended position) may be clearly indicated (reference numeral 53b). The recommended car is a car that can shorten the travel time (the travel cost can be reduced) such as the position closest to the stairs 52e.

  When the user selects a “complete” icon arranged above the drum roll 53a in a state where a certain car is selected as the boarding position, the selected car is set as the boarding position. Then, the search condition setting unit 151 sets this boarding position as a search condition. By transmitting such a search condition to the server 2, the position specifying unit 233 can specify the boarding position. When the user selects the “Cancel” icon, this screen disappears.

  The screen as shown in the figure can be generated when the information receiving unit 153 acquires the station premises information from the station premises information database 223 when a certain station is designated.

  FIG. 8 is a diagram illustrating another example of a screen for accepting an input of a boarding position from a user. In the drum roll 53a in the figure, an icon 52c indicating that there is an escalator near the 12th vehicle from the front, an icon 52d indicating that there is a stairs near the 12th vehicle from the front, and an elevator near the 13th vehicle from the front. An icon 52e indicating that there is is included. Thus, by showing the positional relationship between each vehicle and the facility, the user may be assisted in selecting the boarding position.

  As shown in FIG. 7 and FIG. 8, the convenience of the user can be improved by displaying the position of a facility such as a recommended car or an escalator as additional information.

  7 and 8 are examples of screens for the user to set the boarding position, but a similar screen for inputting the getting-off position may be displayed on the output unit 13. For example, when going to a restaurant in a getting-off platform, it is desirable that the user can specify the getting-off position.

  As a third example, the position specifying unit 233 can specify a position based on a combination of a route before transfer in a transfer, a transfer station, and a route after transfer. More specifically, as shown in FIG. 5, the boarding position and the getting-off position may be specified from the relationship between the facility such as stairs used for transfer and the stop position of the train, and the boarding for each combination. The position and the getting off position may be stored in advance.

  The travel time required for the transfer is the positional relationship between the boarding position (or getting off position) of the train before transfer and the facility used for transferring, and the boarding position (or getting off of the train after transfer) and the facility used for transferring. It can be estimated based on at least one of the positional relationship with the (position).

  As a fourth example, the position specifying unit 233 can specify a position based on a user attribute. For example, if the user is an elderly person, a pregnant woman, an injured person, or a pacemaker, a vehicle with a priority seat may be specified as the boarding position, and if a user in a wheelchair, a vehicle with a wheelchair space may be specified as the boarding position. Further, if the user is a young woman, a female-only vehicle may be specified as the boarding position. Such user attributes may be registered in advance in the server 2 by the user or may be included in the search conditions.

  As a fifth example, the position specifying unit 233 may specify the position based on the user's preference. For example, when the user is a smoker, a vehicle near the smoking area may be set as the boarding position. Alternatively, the determination may be made based on whether or not a woman-only vehicle is desired, whether or not a green vehicle is desired, whether or not a weakly-cooled vehicle is desired, whether or not a vehicle with priority seats is desired, or whether or not a smoking vehicle is desired. Such user preferences may be registered in advance in the server 2 by the user, or the server 2 may estimate the user preferences from the user's behavior history.

  As another example, the position may be specified in consideration of the weather and the season. For example, in the case of rain or fine weather in summer, there is a high possibility that the user gets on from a vehicle that stops in a range where the roof on the platform is located. Therefore, you may specify the vehicle which stops in the range with a roof in a platform as a boarding position. When the season is summer, a vehicle that stops near the cooling outlet in the home or a vehicle that stops in a range where the roof is on the home may be specified as the boarding position. On the other hand, when the season is winter, a vehicle that stops near the waiting room installed on the platform may be specified as the boarding position.

  In order to improve the accuracy of position specification, the above-described examples may be combined, or the boarding position and the getting-off position may be specified by other methods.

(Second Embodiment)
In the second embodiment described below, a route that arrives at the destination earlier after the route search is searched again. Hereinafter, a description will be given focusing on differences from the first embodiment.

  FIG. 9 is a flowchart showing another example of the processing operation of the information processing system 100 of FIG. Hereinafter, description will be given using the route information of the user U2 shown in FIGS.

  Steps S1, S2, S11 to S16 are the same as those in the first embodiment. After performing the route search in step S15, the route search unit 235 determines whether or not the destination can be reached earlier if the travel time required for transfer is shortened. More specifically, the route search unit 235 can shorten the travel time required for transfer by changing the boarding (alighting) position, and as a result, determines whether or not one or more previous trains can be boarded (step S17). ).

  In the example shown in FIGS. 3 to 6, the user U2 arrives at the B station at 10:40, and the travel time required for the transfer is 10 minutes. For this reason, the route information generated in step S15 indicates that the train departs at 10:55. However, if this travel time is reduced to less than 5 minutes, you can get on the 10:45 train. Therefore, the route search unit 235 determines that the destination can be reached earlier if the travel time required for transfer is shortened.

  Returning to FIG. 9, when such a determination is made (YES in step S <b> 17), the route search unit 235 searches again for a route for arriving at the destination earlier using the previous train (step). S18).

  In the example shown in FIGS. 3 to 6, a route on a train that departs from station B at 10:45 is obtained by route search. In order to get on this train, it is necessary to make the travel time required for transfer less than 5 minutes. Therefore, the route search unit 235 also determines how to move. Referring to FIG. 5, at station B, if you get off from car No. 4 of the P-line train, the travel time required to transfer to the Q-line train can be reduced to 3 minutes.

  Therefore, the route search part 235 produces | generates the route information which shows getting off from the 4th car of a P-line train in B station. More specifically, the route information may indicate that the user takes the fourth car (not the first car shown in FIG. 4) of the P-line train at the A station. Alternatively, the route information may indicate that the user takes the first car on the P-line train at the A station, moves in the train before arriving at the Q station, and gets off at the fourth car.

  When new route information is generated, the information transmission unit 236 transmits information indicating that there is a route that arrives earlier and new route information to the terminal device 1 (step S19). The information transmission unit 236 may push such information to the terminal device 1.

  In response to this, the information receiving unit 153 of the terminal device 1 receives information indicating that there is a route that arrives earlier and new route information (step S3). Then, a screen for inquiring the user whether or not to switch to new route information is displayed on the output unit 13. When the user designates switching to new route information via the operation input unit 12 (YES in step S4), new route information is output to the output unit 13 (step S5).

  Thereby, the user can know the route for arriving at the destination earlier.

  In addition, various deformation | transformation can be considered in FIG. For example, when it is determined in step S17 that there is a route that arrives at the destination earlier, it may be transmitted to the terminal device 1 before performing the route search again. Then, when the user requests new route information, the route search unit 235 may search for a new route.

  As described above, in the second embodiment, the route search is performed again in consideration of the position on the transportation facility, so that the route arriving at the destination earlier can be presented to the user.

(Third embodiment)
In the first and second embodiments described above, a position where the user gets on (or gets out of) the transportation facility is specified, and a route search corresponding to the position is performed. On the other hand, in the third embodiment described below, a position where the user gets on the transportation facility (or gets off the transportation facility) during the route guidance is specified, and the route guidance according to the position is performed.

  FIG. 10 is a block diagram showing a schematic configuration of an information processing system 100a according to the third embodiment of the present invention. Hereinafter, the difference from FIG. 1 will be mainly described.

  The control unit 15a of the terminal device 1a includes a route guide unit 154. The route guidance unit 154 provides route guidance to the user based on the guidance information generated by the server 2a. As an example, when the position of the terminal device 1a measured by the position measurement unit 14 matches the guidance point set in the guidance information, the route guidance unit 154 displays the right / left turn timing and the facility serving as a mark on the output unit 13. . The route guidance unit 154 performs such route guidance until the position of the terminal device 1a matches the destination.

  The control unit 23a of the server 2a includes a route information acquisition unit 241, a guidance information generation unit 242, a position specification unit 243, and a travel time estimation unit 244 in addition to the information reception unit 231 and the information transmission unit 236.

  The route information acquisition unit 241 performs route search using information stored in each database, and acquires route information indicating a route from the departure point to the destination set in the search condition. In the present embodiment, it is assumed that transportation such as a train is used for at least a part of the route and that there is a transfer. The route information includes a specific time such as using a train that departs from a certain station at what hour and minute. The route information acquisition unit 241 may acquire predetermined route information such as a commute route without performing route search.

  The guide information generation unit 242 generates guide information for guiding the user to the destination along the route based on the route information. The guidance information includes guidance points set at nodes and the like and guidance contents at the guidance points. The guidance information is transmitted to the terminal device 1a by the information transmission unit 236.

  The position specifying unit 243 specifies the position where the user actually gets on the transportation facility included in the route information and / or the position where the user actually got off during the route guidance, and displays the position information indicating the identified position. Generate. When the transportation is a train, the former is called a boarding position and the latter is called a getting-off position.

  Various methods for specifying the position are conceivable. Similarly to the first embodiment, the boarding position or the getting-off position may be specified based on the station premises information. Or during a route guidance, a screen as shown in Drawing 7 may be outputted from output part 13, and a user may specify a boarding position or a getting-off position. Moreover, you may specify based on the combination of the route before transfer, and the route after transfer.

  As another method, a boarding position may be specified by providing a radio device in a train and connecting the radio device and the terminal device 1a. Or you may identify a boarding position by the terminal device 1a receiving the identification signal which pinpoints a boarding position from the radio | wireless apparatus in a train.

  Moreover, you may identify a boarding position based on the position of the terminal device 1a which the position positioning part 14 measured. Furthermore, when the terminal device 1a has an acceleration sensor, the boarding position may be calculated by autonomous navigation based on the acceleration information. More specifically, it is possible to detect that the staircase has been fully climbed (or descended) based on the acceleration information, and the boarding position can be specified based on the moving distance from that point. You may identify a boarding position using both the acceleration of the terminal device 1a, and its position.

  When specifying the boarding position using the acceleration and position of the terminal device 1a, the boarding position and the getting-off position may be specified in the terminal device 1a, and the obtained position information may be transmitted to the position specifying unit 243 of the server 2a. . Alternatively, information indicating the acceleration and position of the terminal device 1a may be transmitted to the position specifying unit 243 of the server 2a, and the position specifying unit 243 may specify the position.

  In addition, each example described in the first embodiment may be applied.

  Based on the specified position, the travel time estimation unit 244 travels from the transportation facility to a predetermined position on the route being route-guided, particularly from the route before transfer to the route after transfer. Estimate the travel time of. A specific estimation method is the same as that of the travel time estimation unit 234 in FIG.

  Further, the guidance information generation unit 242 determines whether or not it is in time for a transfer on the route being route-guided based on the travel time estimated by the travel time estimation unit 244. More specifically, the guidance information generation unit 242 determines whether or not the user can move to the platform on the post-transfer route by the departure time of the train on the post-transfer route. And the guidance information containing the information of whether it is in time is newly produced | generated, and it transmits to the terminal device 1a from the information transmission part 236. Since the travel time is estimated from the specified position, the guide information generating unit 242 generates guide information according to the specified position.

  FIG. 11 is a sequence diagram illustrating an example of a processing operation of the information processing system 100a in FIG. First, the search condition setting unit 151 of the terminal device 1a sets a search condition. The search condition is transmitted to the server 2a by the information transmission unit 152 (step S21).

  In response to this, the information receiving unit 231 of the server 2a receives the search condition (step S31). Then, the route information acquisition unit 241 performs a route search based on the search condition, and acquires route information indicating a route from the departure place to the destination (step S32). Here, the travel time such as the transfer time in the route information may be an average time without considering the boarding position. Alternatively, as described in the first embodiment, it may be a more accurate time considering the boarding position and the like.

  Further, the guide information generating unit 242 generates guide information based on the route information (step S33). And the information transmission part 236 transmits this guidance information to the terminal device 1a (step S34). The information receiving unit 153 of the terminal device 1a receives guidance information (step S22). Thus, the terminal device 1a and the server 2a are in the route guidance mode.

  In the route guidance mode, the route guidance unit 154 of the terminal device 1a provides route guidance to the user based on the guidance information and the position of the terminal device 1a measured by the position positioning unit 14 (step S23).

  On the other hand, if there is a transfer to the destination in the route guidance mode (YES in step S35), the position specifying unit 243 of the server 2a specifies the user's actual boarding position or getting-off position for the train before transfer. (Step S36). Then, based on the identified position, the movement time estimation unit 244 estimates the movement time required for transfer (step S37). Furthermore, the guidance information generation unit 242 compares the route information being guided with the estimated travel time, and generates guidance information including information on whether or not to make a transfer (step S33). This guidance information is transmitted to the terminal device 1a (step S34), and whether or not the transfer is in time is presented to the user as part of the route guidance (steps S22 and S23).

  The above processing is repeated until there is no transfer on the route (NO in step S35). When the user arrives at the destination, in other words, when the position of the terminal device 1a coincides with the destination (YES in step S24), the route guidance ends.

  FIG. 12 is a diagram illustrating an example of route guidance indicating whether or not to make a transfer. When it is not in time for the transfer at the specified boarding position, the output unit 13 may simply display that it is not in time for the transfer. Moreover, when it is not in time to get off from the boarding position, it may be displayed how the travel time is shortened. For example, you may urge to move to the vicinity of the recommended car in time for the transfer. In addition, it may be urged to change quickly instead of the normal speed.

  Moreover, when it is in time for a transfer at the specified boarding position, it may be simply displayed on the output unit 13 that it is in time for the transfer. Moreover, although it is in time for the transfer, a point to be noted in the transfer may be notified. For example, when getting off from the boarding position, since the stairs of the transfer station platform are crowded, it may be notified that the movement is expected to take time.

  Thus, in the third embodiment, the position where the user got on the train (the position where the user got off) is specified, and it is determined whether or not it is in time for the transfer. Therefore, it can be shown to a user whether it is in time for a transfer, and suitable route guidance according to a user's position can be performed.

  In the third embodiment described above, guidance information is generated according to whether or not it is in time for the transfer. In addition, you may generate | occur | produce the guidance information according to whether it gets off from transportation and it arrives at the arrival time to the destination set to the search conditions. In this case, the travel time estimation unit 244 may estimate the travel time from the transportation facility to the destination.

(Fourth embodiment)
In the third embodiment described above, the user is notified whether the transfer is in time. On the other hand, the fourth embodiment described below performs reroute in consideration of the user's actual boarding position and getting-off position.

  FIG. 13 is a sequence diagram illustrating another example of the processing operation of the information processing system 100a in FIG. Hereinafter, the difference from FIG. 11 will be mainly described.

  When there is a transfer on the route to the destination (YES in step S35), the position specifying unit 243 of the server 2a specifies the user's actual boarding position or getting-off position for the train before transfer (step S36). Then, the route information acquisition unit 241 performs route search again in consideration of the specified position (step S32).

  Specifically, the route information acquisition unit 241 may get off at the transfer station from the specified boarding position, and search for the route in the transfer station premises again using this place of departure as the departure point.

  Alternatively, the travel time estimation unit 244 estimates the travel time required for the transfer in that case, assuming that the train gets off at the transfer station from the specified boarding position. Then, the route information acquisition unit 241 may search for a route including a train in time for the transfer again based on the travel time.

  For example, in consideration of the travel time based on the actual boarding position, there may be cases where the train obtained by the first route search is not in time. In this case, a route using one or several trains after that or a route using another transportation means can be obtained.

  In addition, in consideration of the travel time based on the actual boarding position, there is a case where a train preceding the train obtained by the first route search can be boarded. In this case, a route that arrives at the destination earlier can be obtained using the previous train.

  And the guidance information generation part 242 produces | generates new guidance information based on new route information (step S33). Then, route guidance based on new guidance information is performed (steps S34, S22 to S24).

  Thus, in the fourth embodiment, the boarding position is specified and a new route is searched. Therefore, it is possible to perform appropriate route guidance according to the user's boarding position.

  In the third and fourth embodiments, the example of specifying the boarding position has been mainly described, but the same processing may be performed by specifying the getting-off position.

  At least a part of the information processing system described in the above-described embodiment may be configured by hardware or software. When configured by software, a program for realizing at least a part of the functions of the information processing system may be stored in a recording medium such as a flexible disk or a CD-ROM, and read and executed by a computer. The recording medium is not limited to a removable medium such as a magnetic disk or an optical disk, but may be a fixed recording medium such as a hard disk device or a memory.

  Further, a program that realizes at least a part of the functions of the information processing system may be distributed via a communication line (including wireless communication) such as the Internet. Further, the program may be distributed in a state where the program is encrypted, modulated or compressed, and stored in a recording medium via a wired line such as the Internet or a wireless line.

  Further, the information processing system may be functioned by one or a plurality of information processing apparatuses. When a plurality of information processing apparatuses are used, one of the information processing apparatuses may be a computer, and the function may be realized as at least one means of the information processing system by the computer executing a predetermined program.
