Hereinafter, a traffic information presentation device according to an embodiment of the present invention will be described with reference to the drawings as necessary.

FIG. 1 shows a schematic configuration of a traffic information presentation apparatus according to an embodiment of the present invention. The traffic information presentation device shown in FIG. 1 is realized on a mobile device including an acceleration sensor 101 and a GPS (Global Positioning System) unit 102, for example. Mobile devices can be, for example, mobile phones and personal digital assistants (PDAs). The GPS unit 102 is appropriately operated as needed and periodically, receives a signal transmitted from a positioning satellite, and indicates a moving position of the mobile device, that is, coordinates indicating a moving position of a user carrying the mobile device ( (Latitude and longitude) is calculated, and position information regarding the movement position is acquired. Alternatively, the GPS unit 102 transmits a signal received from the positioning satellite to a GPS server (not shown) connected via a communication network such as the Internet, and receives position information (latitude and longitude) regarding the moving position from the GPS server. You may receive it.

In the present embodiment, an example is described in which a mobile device includes a GPS unit as an example of a position information acquisition unit that acquires position information. However, the position information acquisition unit is not limited to the GPS system, and is not portable. Location information is acquired using a base station positioning method using a received signal from a base station in a telephone network, a Wi-Fi based positioning method using a received signal from a wireless LAN base station, or a combination thereof. May be.

The acceleration sensor 101 detects triaxial acceleration acting on the mobile device as the user moves, and transmits acceleration information indicating the detected triaxial acceleration to the movement state estimation unit 103. When the movement status estimation unit 103 receives the acceleration information from the acceleration sensor 101, the movement status estimation unit 103 estimates the movement status of the user carrying the mobile device based on the received acceleration information. More specifically, the movement state estimation unit 103 extracts feature amounts that change according to the user's movement state from the detected three-axis accelerations, classifies the extracted feature amounts by a neural network, and moves the user. Estimate the situation. The moving state includes a stationary state indicating that the user is stationary, a riding state indicating that the user is on a vehicle such as a train and a bus (also referred to as transportation), and a state where the user is walking. A walking state is included.

In the description of the embodiment, trains and buses are specifically described as examples of transportation facilities for which traffic information is to be presented. However, transportation facilities for which traffic information is to be presented are limited to this. First, trains, buses, ships, airplanes, etc. operated according to a predetermined diagram can be included. In the present embodiment, transportation facilities such as trains, buses, ships, and airplanes are referred to as vehicles, and facilities such as railway stations, bus stops, and airports where users get on and off the vehicles are referred to as stations.

From the movement state estimation unit 103, movement state information indicating the movement state of the user is transmitted to the boarding / alighting determination unit 104 and the movement distance estimation unit 111. The boarding / alighting determination unit 104 detects a transition of the user's movement status from the movement status information, and determines whether the user has boarded the vehicle or got off the vehicle. The boarding / alighting determination unit 104 determines that the user has boarded the vehicle when the movement state has changed from the walking state to the boarding state, and transmits boarding time information indicating the time when the user has boarded the vehicle to the boarding route holding unit 105. . Further, when the moving state transitions from the boarding state to the walking state, the boarding / alighting determination unit 104 determines that the user has got off the vehicle, and receives the boarding time information indicating the time when the user got off the vehicle from the boarding route holding unit 105. Send.

The boarding route holding unit 105 stores a station POI database 106 that stores station POI (Point of Interest) data in which station names (including bus stops), route names, and station positions (latitude and longitude) are described in association with each other. I have. When the boarding route holding unit 105 receives the boarding time information from the boarding / alighting determination unit 104, the boarding route holding unit 105 receives from the GPS unit 102 the position at the boarding time, that is, the position information indicating the boarding position. Subsequently, the boarding route holding unit 105 refers to the station POI data based on the received position information, specifies the station (boarding station) on which the user boarded, and holds the specified boarding station as first route information. The first route information may include information on the boarding position estimated by the boarding route holding unit together with the boarding station name.

Further, when the boarding route holding unit 105 receives the getting-off time information from the getting-on / off judging unit, the boarding route holding unit 105 receives the position at the getting-off time, that is, the position information indicating the getting-off position from the GPS unit 102. Subsequently, the boarding route holding unit 105 refers to the station POI data based on the received position information, specifies the station where the user got off (alighting station), and holds the specified getting-off station as second route information. The second route information may include the boarding station name and the getting-off station name of the vehicle that the user has boarded immediately before. The second route information may include information on the boarding position and the getting-off position estimated by the boarding route holding unit together with the boarding station name and the getting-off station name.

The boarding route holding unit 105 holds at least one of the first and second route information as the boarding route information, and thus holds at least one of the boarding station name and the getting-off station name. The second route information is transmitted from the boarding route holding unit 105 to the history holding unit 107.

The history holding unit 107 holds boarding route history data including a history of routes used by the user so far, and adds second route information received from the boarding route holding unit 105 to the boarding route history data. The boarding route history data is stored in the history database 108.

The route candidate selection unit (also referred to as a route selection unit) 109 uses the first or second route information held by the boarding route holding unit 105 and the boarding route history data held by the history holding unit 107, so that the user can Next, select the transportation route candidate to be used. The route candidate selection unit 109 includes station timetable data included in the station POI data, and causes the display unit 110 as a user interface to display timetable data related to the selected route candidate of the transportation facility.

The movement distance estimation unit 111 receives the movement state information from the movement state estimation unit 103, and estimates the movement distance of the user using the received movement state information. A boarding / alighting position correction unit (also referred to as a position correction unit) 112 corrects the boarding / alighting position when position information cannot be acquired at the time of boarding or alighting or when the positioning accuracy of the GPS unit 102 is low. For the correction of the position information, the position information acquired by the GPS unit 102 before and after the boarding time or the getting-off time and the movement distance estimated by the movement distance determination unit 111 are used. The history correction unit 113 corrects the boarding route history data using a route name or the like included in the station POI data.

Referring to FIG. 2, a method of estimating the getting-off station in boarding route holding unit 105 will be described. As shown in FIG. 2, the movement state estimation unit 103 generates time-series data indicating the movement state of the user using the acceleration information from the acceleration sensor. In the example shown in FIG. 2, the user is in the riding state from time t0 to time t1, and is in the walking state after time t1. The boarding / alighting determination unit 104 detects that the moving state transitions from the boarding state to the walking state at time t1, and determines that the user has got off the vehicle. When it is determined that the user has got off the vehicle, the GPS unit 102 acquires position information at the getting-off time t1. The boarding / alighting line holding unit 105 refers to the station POI data with the acquired position information, and identifies the station closest to the getting-off position as the getting-off station.

Also, identification of the boarding station is executed in the same manner as identification of the getting-off station. The boarding / alighting determination unit 104 determines that the user has boarded the vehicle when it detects that the moving state changes from the walking state to the boarding state. When the boarding / alighting determination unit 104 determines that the user has boarded the vehicle, position information at the boarding time is acquired by the GPS unit 102. The boarding / alighting line holding unit 105 refers to the station POI data at the obtained boarding position, and estimates the station closest to the boarding position as the boarding station. Here, the judgment of getting on and getting off is performed by ignoring the stationary state generated between the boarding state and the walking state.

In stations such as terminal stations underground or indoor, the GPS unit 102 cannot acquire position information because it cannot receive a signal from a positioning satellite, or even if it can be acquired, positioning accuracy may be low. . In this case, in order to specify the boarding or getting off station, it is necessary to correct the boarding or getting off position. A method for correcting the boarding and getting-off positions will be described later.

In addition, when the movement state estimation unit 104 can determine the type of vehicle on which the user is riding (for example, train, bus, etc.) by analyzing the acceleration information, the route information holding unit 105 is determined. A boarding station and an alighting station may be narrowed down using classification.

FIG. 3 shows an example of boarding route history data held by the history holding unit 107. As shown in FIG. 3, the boarding route history data includes a set of boarding stations and alighting stations, and a history ID as information on routes that the user has used so far. The history ID is a unique value given to the data in the order in which the data is added to the boarding route history data. Although not shown in FIG. 3, when the user continues to walk for more than a certain time after getting off the vehicle, the history holding unit 107 determines that the user's movement using the transportation has ended, and the movement ends. Can be described in the boarding route history data. In the example of FIG. 3, the user travels from Hamadayama Station to Shibuya Station by train, transfers at Shibuya Station, travels from Shibuya Station to Gotanda Station, and then travels from Gotanda Station to Toshiba Science Center Station by bus. The series of movements from Hamadayama Station to Toshiba Science Museum Mae Station has been completed. In the boarding route history data in FIG. 3, the next movement starts from the movement from Kawasaki to Tokyo.

Referring to FIG. 4, a method for estimating a route candidate of the next transportation system on which the user gets on will be described. Here, an example will be described in which information about route candidates for transportation is presented to the user after the user has moved from Hamadayama Station to Shibuya Station by train. The boarding route holding unit 105 generates second route information indicating that the boarding station is Hamadayama Station and the boarding station is Shibuya Station after the user gets off the train at Shibuya Station. The route candidate selection unit 109 searches the boarding route history data for data that matches the boarding station and the getting-off station indicated by the second route information, and acquires the history ID of the data. Subsequently, the route candidate selection unit 109 extracts data having a history ID next to the history ID as a route of a transportation facility that the user uses next. In the example shown in FIG. 4, data with

history IDs

0002, 0009, and 0014 are extracted as the next transportation route, that is, the route candidate selection unit 109 immediately after moving from Hamadayama Station to Shibuya Station. Routes from Omotesando Station to Shimbashi Station, routes from Shibuya Station to Komazawa University Station, and routes from Shibuya Station to Gotanda Station, which are transportation routes, are selected as the next transportation route candidates. The display unit 110 presents information related to these selected routes to the user.

Further, when the user is on the vehicle, the first route information held by the boarding route holding unit 105 is used to select route candidates for the next transportation to be used by the user. In this case, data matching the boarding station indicated by the first route information is acquired from the boarding route history data, and the next data after the acquired data is selected as a route candidate for the next transportation.

FIG. 5 shows an example of information presented to the user related to route candidates for transportation. As shown in FIG. 5, the display unit 110 displays timetable data for each route selected by the route candidate selection unit 109. The displayed timetable data can include, for example, departure time, required time, arrival time, and the like. When the candidate route candidate is acquired using the second route information, the timetable of the time zone immediately after the current time is displayed, and the next candidate route candidate is acquired using the first route information The timetable of the time zone in which the transfer is possible at the station where the user is assumed to get off is displayed. In this embodiment, since both the boarding station and the getting-off station are determined as the next movement of the user, it is a timetable of the station where the user gets next, and the direction from the boarding station to the getting-off station The timetable can be presented to the user, and information relating to trains that do not stop at the destination station (for example, limited express etc.) is not displayed on the timetable, or the color is displayed in a different color to alert the user to attention. . In addition, the display unit 110 may preferentially present information about a vehicle that arrives at the getting-off station early. Furthermore, the order of the timetable displayed on the display unit 110 may be the order in which history IDs are large, that is, the order in which the history is new, the order in which the boarding frequency is high, or another order.

FIG. 6 shows an example of a processing procedure for presenting traffic information to the user. As shown in step S601 of FIG. 6, the movement state estimation unit 103 estimates the movement state of the user based on the acceleration information from the acceleration sensor. In step S602, the boarding / alighting determination unit 104 detects a transition of the movement status. If it is determined by the getting-on / off determining unit 104 that the user has got on the vehicle or the user has got off the vehicle, the procedure proceeds to step S603, and otherwise, steps S601 and S602 are repeatedly executed.

When the user's boarding or getting-off operation is detected in step S602, it is determined in step S603 whether or not the user is currently on the vehicle. When the user is not in the boarding state, the boarding route holding unit 105 specifies the getting-off station based on the position information acquired by the GPS unit 102 in step S604. In this case, the boarding route holding | maintenance part 105 has specified the boarding station corresponding to this alighting station in advance. In step S605, the boarding route holding | maintenance part 105 produces | generates the 2nd route information which shows a boarding station and an alighting station. In step S <b> 606, the history holding unit 107 adds the second route information to the boarding route history database 108. In step S607, the route candidate selection unit 109 searches for data in the boarding route history database 108 that matches the boarding station and the getting-off station included in the second route information. In step S611, the route candidate selection unit 109 presents to the user information related to the route indicated by the data next to the boarding station and the getting-off station included in the second route information.

When it is determined in step S603 that the user is on board, the boarding route holding unit 105 specifies the boarding station from the position information acquired from the GPS unit 102 in step S608. Subsequently, in step S609, the boarding route holding unit 105 generates first route information indicating a boarding station on the currently boarding route. In step S610, the route candidate selection unit 109 searches for data in the boarding route history database 108 that matches the boarding station included in the first route information. In step S611, the route candidate selection unit 109 presents the user with information related to the route indicated by the data next to the boarding station included in the first route information.

As described above, in the present embodiment, information related to the transportation facility that the user is supposed to get on next is presented to the user. The presented traffic information may be displayed on, for example, a standby screen of a mobile phone.

Next, a method of estimating the boarding station and the getting-off station when the position information cannot be obtained at the boarding time and the getting-off time or when the positioning accuracy is low even if it can be obtained will be described.

Referring to FIG. 7, a method for estimating the getting-off position when position information at the getting-off time cannot be obtained will be specifically described. In the example shown in FIG. 7, the user is in the riding state from time t0 to time t2, and is in the walking state after time t2. In this example, the getting-off position cannot be acquired at time t2 when it is determined that the user has got off, but the position information is acquired at times t1 and t3 before and after the getting-off time t2. In this case, the boarding / alighting point correction unit 112 assumes that the getting-off position is on a straight line connecting the position acquired immediately before getting off and the position acquired immediately after getting off, and the estimated moving distance from time t1 to time t2. The getting-off position is estimated from the ratio with the estimated moving distance from time t2 to time t3. The estimated movement distance is calculated by the movement distance estimation unit 111. The calculation of the estimated moving distance is executed on the assumption that the vehicle moves at a speed of 4 km / h when walking and moves at a speed of 30 km / h when getting on. The movement distance estimation unit 111 calculates a rough movement distance by multiplying the movement speed according to the movement situation of the user and the elapsed time in the movement situation. As described above, when the getting-off position cannot be obtained, or even if the getting-off position can be obtained, if the positioning accuracy is low, the position information obtained before and after the getting-off time, the moving distance during the ride, and the walking The getting-off position is estimated using the travel distance, and the getting-off station is estimated by the boarding route holding unit 105 using the getting-off position estimated by the getting-on / off position estimating unit 112.

It should be noted that the movement state estimation unit 103 can determine the other movement states described above (that is, the stationary state, the riding state, the walking state), for example, the state of riding on a train, a bus, a bicycle, or the like. In this case, a different moving speed may be set for each of the moving situations, and the moving distance of the user may be estimated.

Further, when executing these corrections, the display unit 110 is used to notify the user that corrections are to be performed, and a plurality of correction candidate stations are presented to allow the user to select an appropriate boarding station or alighting station. You may do it.

FIG. 8 shows an example of a processing procedure for correcting the getting-off position (boarding position) and estimating the getting-off station (boarding station). The procedure for correcting the boarding position and estimating the getting-off station is executed in the same procedure as the processing procedure for correcting the getting-off position and estimating the getting-off station. As shown in step S801 of FIG. 8, the position information obtained by the GPS unit 102 and the estimated movement distance calculated by the movement distance estimation unit 111 are continuously stored. In step S802, the boarding / alighting determination unit 104 detects a transition of the movement status. If it is determined by the getting-on / off judging unit 104 that the user has got off the vehicle (get on the vehicle), the procedure proceeds to step S803. Otherwise, steps S801 and S802 are repeatedly executed.

In step S803, if it is determined that the user gets off the vehicle (gets on the vehicle), the position at the time immediately before the time of getting off (boarding) and the estimated travel distance from the time immediately before to the time of getting off (boarding) Is memorized. Next, in step S804, the GPS unit 102 is operated and continuously operated until position information is acquired (step S805). In the acquisition of the position information shown in steps S804 and S805, the position information with low positioning accuracy calculated based on the received signals from a small number (for example, two) of positioning satellites is discarded without using it. It may be. In order to reduce power consumption, the interval at which the GPS unit 102 is operated may be intentionally wide.

In step S806, the position information acquired by the GPS unit 102 in steps S804 and S805 and the estimated travel distance from the getting-off (boarding) time to the time when the position information is acquired are recorded. In step S807, the position of getting off (riding) is calculated using the position information before and after the getting-off (riding) time and the estimated moving distance. In step S808, the station POI data is referred to by the calculated getting-off (riding) position. As a result, the exit station (boarding station) is corrected.

As described above, in the present embodiment, the boarding station and the getting-off station can be estimated even when the GPS unit 102 cannot obtain the position information at the boarding and getting-off time.

Next, a method for correcting the boarding route history data will be described. In a station such as a terminal station that is underground or indoor, the position information may not be obtained by the GPS unit 102 at the time of getting on or off, and the position information after the user has moved to a position where a signal from the positioning satellite can be received. May be acquired. Moreover, the positioning accuracy by the GPS unit 102 is low, and an error may be included in the acquired position information. As a result, the boarding station or the getting-off station may be erroneously estimated, and erroneous data is added to the boarding route history data.

A method of correcting the boarding route history data will be described with reference to a specific example of FIG. FIG. 9 shows a moving route in which a user gets on the Inokashira Line from Hamadayama Station 901 to Shibuya Station (Inokashira Line) 902, transfers at Shibuya Station and gets on the Yamanote Line from Shibuya Station (Yamanote Line) 904 to Gotanda Station 906. An example is shown. In the example of FIG. 9, when changing at Shibuya Station, an unloading position 908 is acquired around Shibuya Station 903 on the Fukutoshin Line instead of Shibuya Station 902 on the Inokashira Line due to the error of the GPS unit 102. A position 909 is acquired around Ebisu Station 905. In this example, it is assumed that the boarding position 907 at Hamadayama Station 901 and the boarding position 910 at Gotanda Station 906 are acquired with high accuracy, and the boarding station and the boarding station are correctly identified.

The correction of the boarding route history data is executed after the user gets off the vehicle and the position information is acquired. When correcting the getting-off station in the boarding route history data, a plurality of stations within a certain distance from the getting-off position are extracted from the station POI data, and the route name described in association with the extracted station is the name of the boarding station. A station that matches is identified as a disembarking station. The boarding route history data is rewritten and corrected at the specified getting-off station. When correcting the boarding station of boarding route history data, it is performed by the same method as the correction of the getting-off station of boarding route history data. When correcting both the boarding station and the getting-off station in the boarding route history data, a combination having the same route name among a station existing within a certain distance of the boarding position and a station existing within a certain distance of the getting-off position It is specified as a boarding station and an exit station, respectively. In addition, when it is estimated that there is a transfer between stations within a certain distance from the above movement situation, the station closest to the boarding position at the time of transfer is selected as the disembarkation station before transfer among the multiple stations on the route before transfer Of the plurality of stations on the route after transfer, the station closest to the alighting position at the time of transfer is selected as the boarding station after transfer.

In the example of FIG. 9, in the correction at the time of getting off at Shibuya Station 902 on the Inokashira Line, as stations within a certain distance from the estimated getting off position 908, Shibuya Station 902 on the Inokashira Line, Shibuya Station 903 on the Fukutoshin Line, The Shibuya station 904 on the Yamanote line is extracted, and among these, the Shibuya station 902 on the Inokashira line, whose route name is the Inokashira line, is specified as the exit station. Moreover, in the correction at the time of getting off at Gotanda Station 906, the station of Yamanote Line around the boarding position 909 is searched, Shibuya Station 904 and Ebisu Station 905 are extracted, and Shibuya Station of Inokashira Line which is a boarding line before transfer. A station on the Yamanote line near 902, that is, Shibuya station 904 is specified as a correct boarding station.

When executing these corrections, the user may be notified that correction is to be performed using the display unit 110, or a plurality of correction candidate stations may be presented for selection by the user.

FIG. 10 shows an example of a procedure for correcting the boarding route history data. As shown in step S1001 of FIG. 10, the correction of the boarding route history data is started when the user's getting-off position is determined after the user gets off the first route. In step S1002, the history correction unit 113 searches for a plurality of stations within a certain distance from each of the first boarding position and the first getting-off position using the station POI data. In step S1003, the history correction unit 113 determines whether there is a combination in which a station around the first boarding position and a station around the first getting-off position have the same route name. When there is a combination of stations having the same route name, the process proceeds to step S1004, and when there is no combination of stations having the same route name, the process proceeds to step S1005. In step S1004, the history correction unit 113 selects a combination having the same route name as the first boarding station and the first getting-off station.

In step S1005, the history correction unit 113 determines whether or not the user is walking for a predetermined time after getting off, for example, 10 minutes or more. That is, in step S1005, it is determined whether or not to change from the first route to the second route at the station where the user got off. If it is determined that the movement has been completed instead of a transfer, this procedure ends. When it is determined that the user has boarded the vehicle within a predetermined time after getting off, position information indicating the second boarding position after the transfer is acquired by the GPS unit 102, and the second boarding station is obtained by the boarding route holding unit 105. The process proceeds to step S1006. In step S1006, the user's movement on the second route ends, and in step S1007, the second getting-off station is estimated. In step S1008, the history correction unit 113 searches for a station on the first route near the first getting-off position and a station on the second route near the second getting-on position, and near the first getting-off position. Among the combinations of the station on the first route and the station on the second route in the vicinity of the second boarding position, it is determined whether there is a combination in which the distance between the stations is within a certain distance. If there is no combination in which the distance between the stations is within a certain distance, the boarding route history data is not corrected and the processing ends. When there is a combination in which the distance between the stations is within a certain distance, the process proceeds to step S1009, and in step S1009, the stations where the distance between the stations is within the certain distance are designated as the first getting-off station and the second boarding station, respectively. The boarding route history data is corrected as follows. In step S1009, when there are a plurality of combinations in which the distance between the stations is within a certain distance, the combination of the stations having the smallest distance between the stations is selected as the first disembarking station and the second boarding station.
