Description

The present invention relates to a technology for providing information to route bus passengers. In particular, this technique is useful when the passenger is a foreigner (passenger who does not understand the local language).
Here, the route bus is a transportation means for which a traveling route is determined and which targets unspecified passengers.

With globalization in recent years, languages used by visiting foreigners are becoming more diverse.
Trains, taxis and buses can be considered as means of transportation when such foreigners move.
In the case of a train, before getting on the train, the person in charge of the dedicated window can issue a ticket in response to a foreigner. On the other hand, in the case of a bus, drivers who are not necessarily strong in foreign languages can not but deal with foreigners as unspecified passengers. And, if it takes time to respond to the problem, getting in and out of other passengers may be hindered, or it may lead to a delay in bus operation.

Such a situation is considered to be likely to occur in a route bus traveling in a sightseeing spot.
In the case of taxis, the driver will be able to respond to foreigners, but it is only necessary to deal with that particular passenger, without causing inconvenience to other passengers due to delays in operation.
As a technology for responding to foreigners as such a passenger, there is, for example, the technology described in the technical document 1. This technology relates to an on-vehicle device mounted on a car, and a foreigner sitting in the back seat selects a language from a row of multiple languages on the back display, and then turns the destination where he wants to go to the back display talk. Then, the translated content is translated into Japanese based on the language used by the translation unit. Then, the Japanese translation is output from the front speaker, and the guidance from the current position to the destination is made to correspond to the current position, and is output from the rear speaker in the use language described above.

JP, 2014-182049, A

In the case of a taxi, it is possible to take time to select the language used and confirm the destination without being aware of other passengers as much as a bus, but in the case of a bus it is a quick passenger Response is required.
It is also assumed that the first utterance of a foreigner after selecting a language from a plurality of languages is not an utterance about a destination to which the user wants to go, and it is also assumed that it takes time to determine the destination. Moreover, the above-mentioned technique may require a translation system with high translation accuracy.
The present invention has been made focusing on the above-described points, and a guide device capable of responding to multiple languages more quickly even if it is a foreigner who does not understand the local language and a route bus equipped with the guide device The purpose is to provide

  In order to solve the problem, one aspect of the present invention is a guidance device installed on a route bus, which displays a world map on a touch panel type display unit and the above display unit, and the desired position of the world map A region selecting unit that enables the user to touch, a language estimating unit that estimates the corresponding language from the position on the world map selected by the touch, and a response in the corresponding language estimated by the language estimating unit; And a guidance presenting unit for presenting guidance information consisting of at least one of a stop and a charge.

  At this time, the guidance presentation unit acquires a voice via the voice input unit according to the notification of the destination confirmation unit that performs notification to inquire the destination in the corresponding language estimated by the language estimation unit and the notification of the destination confirmation unit. A voice acquisition unit, a destination estimation unit that estimates a destination based on the voice acquired by the voice acquisition unit, a charge to a stop corresponding to the destination estimated by the destination estimation unit, or at least one information of the stop is notified And a guidance information notification unit.

According to the aspect of the present invention, by allowing the user to select a language from an image-friendly world map, the passenger can easily present a language that he or she can handle. As a result, it is possible to quickly respond to the language for bus guidance without placing a burden on the bus driver.
Here, if the device side first inquires the destination in the selected corresponding language, the range of the response contents of the passenger is limited to the location information, and the location where the passenger wants to go with simple translation processing and with high accuracy It becomes possible to acquire This leads to the prompting of the guidance presentation.

Next, embodiments of the present invention will be described with reference to the drawings.
The route bus 1 travels along a preset travel route. Several stops are installed along the travel route. The driver of the route bus 1 visually recognizes a passenger assumed to get on the bus 1 in the vicinity of the next stop, or the stop button 11 installed on the route bus 1 is pressed to light the next stop lamp 10 When the user visually recognizes, the local bus 1 is stopped at the next stop, the door is opened, and passengers from the local bus 1 get on and off.

  Here, there are a plurality of methods for getting on and off the bus 1 and getting off. In the case of flat fares, it is often the case that the front and rear pay-as-you-go systems are used by getting in from the front door to pay the fare and leaving from the rear or center door. On the other hand, if the fare changes according to the distance (to the kilometer system / section system), you get on the rear or center door and pay the fare when you get out of the front door. The method is often adopted. In addition, for route buses that travel long distances, buses with only the front door are often adopted because they have long boarding times and a small number of boarding / landing times, and also have the purpose of providing as many seats as possible. In this case, the entrance and exit will be on the front door only, and it will be a pre-ride / pre-advanced post-payment system, but even in this case there may be a case of advance payment. In addition, in the case of postpaid, when taking a ride, take a numbered ticket printed with a number corresponding to the riding place, or hold a predetermined magnetic card over a reading device to obtain boarding information in the magnetic card, thereby driving Person can confirm the fare to be paid.

The present invention is applicable to any boarding route bus as described above.
In the present embodiment, the case where the present invention is applied to the route bus 1 of the front rider / pre-ahead fare type will be described as an example.
In the route bus 1 of the present embodiment, as shown in FIG. 1, the driver's seat 2 is present on the front right side in the vehicle compartment and the toll box 3 is installed on the left side of the driver's seat 2 in top view. A lift door 4 is provided on the side of the driver's seat 2 (the front of the vehicle).

In addition, a plurality of passenger seats (not shown) are installed in a passenger area AREA behind the driver's seat 2. In the passenger compartment, a stop button 11 operable by a passenger is installed, and a next stop lamp 10 for notifying that the stop button 11 is pressed is installed. In addition, a speaker 12 for guidance broadcasting is installed in the vehicle compartment.
Further, a guiding device 5 is installed on the route bus 1 of the present embodiment.

As shown in FIG. 2, the guiding device 5 includes a touch panel type display unit 6, an audio input unit 7 including a microphone, an audio output unit 8 including a speaker, a control unit 9, and a storage unit 13.
The display unit 6 is disposed near the driver's seat 2. Although FIG. 1 illustrates an example in which the display unit 6 is disposed beside the elevator door 4, the display unit 6 may be provided in the toll box 3. In the case of the method of getting on from the rear door away from the driver's seat, the display unit 6 is disposed in the vicinity of the rear door such as the ticket acquisition position.

The display unit 6 has a touch panel type screen, and can supply coordinate data of a touch position to the control unit 9.
As shown in FIG. 3, the storage unit 13 is map position-language map information 13A, an inquiry sentence example 13B, stop identification data 13C, charge list map data 13D, alighting information 13E, stop guidance broadcast data And 13F.

The control part 9 is provided with the area selection part 9A, the language estimation part 9B, and the guidance presentation part 9C, as shown in FIG.
The area selection unit 9A displays a world map as shown in FIG. 5 on the display unit 6 and performs processing for prompting a touch on a desired position of the world map.
The process of the area selection unit 9A will be described with reference to FIG.

  When the region selection unit 9A detects a touch on the display unit 6, as shown in FIG. 6, first, the world map as shown in FIG. 5 is displayed on the display unit 6 (step S10). Prompt the touch. The prompt for the touch (meaning touch on the screen) may also be performed by an image display that displays, for example, the thumb and guides the touch with the finger. The occupant may urge a touch by gesture. It is determined whether there is a touch (touch) on the display unit 6 (step S20), and if there is a touch, coordinate data of the touch position is acquired (step S30).

The language estimation unit 9B performs processing to estimate the corresponding language from the touch position.
While displaying the world map, the language estimation unit 9B specifies the position on the world map corresponding to the touched position from the coordinates of the touch position of the display unit 6. Depending on the touch position, an enlarged map of the area may be displayed to prompt the touch again.
Here, the storage unit 13 has map information 13A of map position-language in which each position (coordinates) of the world map is associated with a specific language.

Next, the process of the language estimation unit 9B will be described with reference to FIG.
The language estimation unit 9B refers to the map information 13A to specify the language related to the area on the world map corresponding to the touched position as a candidate language (step S100).
Next, language estimation unit 9B determines whether there is a plurality of related languages (step S110), and when there are a plurality of candidate languages, the plurality of languages are displayed on the display unit as candidates for the language used. At step S120, a touch for selecting a language to be used is prompted. Thus, even in the case of displaying a plurality of languages, the number of languages to be presented is limited as compared with the case of presenting a large number of language strings in advance, and selection can be performed simply and quickly. is there.

Then, when the user touches the language selection or OK (step S130), the language estimation unit 9B sets the selected language as the corresponding language (step S170). At this time, when neither language nor language candidate is selected, the process proceeds to the process of the area selection unit 9A to prompt the selection again (step S160).
When it is determined in step S110 that the language corresponding to the map position is determined to be one language, language estimation unit 9B displays the language (step S140) and performs selective display of OK / NG (step S150). . In the case of OK, the process proceeds to step S170, and the language is set as a corresponding language. In the case of NG, the process proceeds to the process of the area selection unit 9A to urge the selection again (step S160).

The guidance presentation unit 9C responds to the corresponding language estimated by the language estimation unit 9B through the display unit 6 and the voice output unit 8 to present guidance information consisting of at least one of the bus stop and the fare to the user.
As shown in FIG. 8, the guidance presentation unit 9C of the present embodiment includes a destination confirmation unit 9Ca, a voice acquisition unit 9Cb, a destination estimation unit 9Cd, and a guidance information notification unit 9Ce.

  The destination confirmation unit 9Ca performs notification to inquire the destination in the corresponding language estimated by the language estimation unit 9B. The notification is performed by both the audio output unit 8 and the display on the display unit 6. The contents of the inquiry are, for example, the contents such as “Where are you going? That is, in the storage unit 13, a sentence example 13B of the query is stored for each corresponding language.

The voice acquisition unit 9Cb obtains voice from the notification via the voice input unit 7 according to the notification from the destination confirmation unit 9Ca.
The destination estimation unit 9Cd estimates the destination based on the voice acquired by the voice acquisition unit 9Cb.
The destination estimation unit 9Cd includes a translation unit 20, a syntax analysis unit 21, and a stop identification unit 22, as shown in FIG.

The translation unit 20 translates the voice acquired by the voice acquisition unit 9Cb into Japanese. The translation process may employ a known translation system. The speech content is limited as it translates the response to the query.
The syntax analysis unit 21 analyzes the Japanese syntax translated by the translation unit 20 and specifies a word indicating a destination. Because of the syntax of the response to the query, it is considered that parsing will not be complicated either.

The stop identification unit 22 identifies a stop corresponding to the word indicating the destination identified by the syntax analysis unit 21.
Here, for each stop, the name of the stop and the name of a view point such as a tourist attraction existing near the stop are stored in the storage unit 13 as stop identification data 13C. The vicinity is, for example, within the range of a radius of 500 m from the stop, and the name straddling the two stops is associated with one stop in terms of distance and ease of access.

For tourist spots, it is preferable to store names of structures such as temples and ponds in the tourist spots in association with the stops.
The stop identification data 13C is, for example, as shown in FIG. 11, a data group consisting of a set of a place name and a stop number uniquely assigned to the stop.
The process of the stop identification unit 22 will be described with reference to FIG.

  The stop identifying unit 22 acquires the word indicating the destination identified by the syntax analysis unit 21 (step S200), and the stop identifying data 13C is searched using the word as a key (step S210), and the word is matched with the word Alternatively, it is determined whether there is data of an approximate name (step S220). Abbreviations of various names may be stored instead of the approximation determination.

  When it is determined in step S220 that the stop identification unit 22 extracts the matched stop identification data 13C, the process proceeds to step S230, and the stop number of the data corresponds to the stop of the bus 1 of itself. If it is not the stop of its own bus 1, information of the corresponding bus including the boarding position to the other corresponding bus is displayed (step S250). Here, when a plurality of route buses stop at the same stop, the stop number may be different even if the same stop is used for each route bus. In this case, a plurality of stop numbers may be made to correspond to the place name.

On the other hand, if it is determined in step S230 that the stop number of the data is a number corresponding to the stop number of its own bus 1, the stop of the stop number is determined as the getting-off stop (step S240).
On the other hand, when it is determined in step S220 that there is no corresponding data in the stop identification data 13C, the process proceeds to the destination confirmation unit 9Ca.

The guidance information notification unit 9Ce refers to the map data 13D of the toll list to obtain the charge from the current stop to the stop of the get-off identified by the stop identification unit 22, and the obtained charge and the stop for getting off The notification is made through the voice output unit 8 and the display unit 6.
The guidance information notification unit 9Ce stores the corresponding language estimated by the language estimation unit 9B and the information on the stop to alight from the current stop in the storage unit 13 as alighting information 13E.

  The getting-off information 13E has, for example, a data structure as shown in FIG. That is, it is data in which a stop number for boarding, a stop number for getting off, and a language number assigned to the corresponding language are paired. Here, in the case of the route bus 1, the stop numbers are usually assigned in order (although it may fly), so if the boarding stop number and the getting-off stop number are known, It can be determined.

  Here, the guidance information notification unit 9Ce may output a printed matter in which the stop to which the user has got off and the amount of money up to the stop are displayed in addition to the notification. The printed matter is presented in both Japanese (local language) and the corresponding language. In this case, at the time of getting off, the driver may be presented with this printed matter to pay a fee. As it is written in Japanese, it can be understood by the driver, and since it is written in the corresponding language, it can be understood by the corresponding passenger.

In addition, the route bus 1 is provided with a guide broadcasting system that performs stop guide broadcasting at each stop as shown in FIG.
The guidance broadcast system stores stop guidance broadcast data 13F for the stop in the storage unit 13 for each stop. In the present embodiment, data on stop guidance in a plurality of languages is included as data on stop guidance broadcasting.

The guidance broadcast system of the present embodiment includes a guidance broadcast processing unit 30.
The guide broadcast processing unit 30 executes a process of determining and broadcasting a guide broadcast for the next stop.
The processing of the guidance broadcast processing unit 30 will be described with reference to FIG.
The guide broadcast processing unit 30 of the guide broadcast system acquires information on the next stop (step S300). For example, in the case of a system in which the driver performs guidance broadcasting by sequentially pressing a predetermined button, information on the next stop which can be known from the stopping order can be acquired by pressing the button for the guidance broadcasting.

Next, the guidance broadcast processing unit 30 refers to the getting-off information 13E stored in the storage unit 13, and the next stop is data in the range from the boarding stop to the getting-off stop among the data of the getting-off information 13E. It is determined whether it exists (step S320), and if it exists, the corresponding language of the data of the getting-off information 13E is specified as the language for broadcasting (step S340). If there is a plurality of data, it corresponds to the corresponding language of the plurality of data.
Then, the guide broadcast processing unit 30 temporarily creates the stop guide broadcast in the corresponding language specified, the voice data of the guide broadcast to be broadcast after the stop guide broadcast in Japanese (step S350), and performs the broadcast (step S350) Step S360).

When it is determined in step S320 that there is no corresponding getting-off information 13E in step S320, the guide broadcast processing unit 30 acquires a Japanese guide broadcast in step S330 and performs the broadcast (step S360). .
The control unit 9 also includes an automatic get-off intention display unit 40. If it is determined that the stop next is the same stop as the getting-off stop of the getting-off information 13E stored in the storage unit 13 based on the get-off information 13E stored in the storing unit 13, the automatic stop intention display unit 40 The relay of the lamp 10 is operated so that the passenger presses the stop button 11.

That is, the automatic get-off intention display unit 40 refers to the get-off information 13E and searches the storage unit 13 for information on a stop to get off that matches the next stop, and stops at the stop that matches the next stop. If it is determined that the getting-off information 13E having the information exists, the same signal as the pressing of the stop button 11 that the passenger contacts or presses to indicate that the next stop will be given is supplied to the relay. Execute the same process as when the push button is pressed. When this execution process is performed, even when the passenger does not press the stop button 11, the next stop lamp 10 (explicit lamp) which clearly indicates that the stop button 11 is pressed is lit.
When the next stop lamp 10 is on, the driver stops the bus 1 at the stop and opens the lift door 4.
