Embodiments of the present invention will be described below in detail with reference to the drawings.
[First Embodiment]
FIG. 1 is an explanatory diagram of an information processing apparatus as an example of a route map display system according to the first embodiment. FIG. 1A is an external view of the information processing apparatus 1, and FIG. 1B is a hardware configuration diagram of the information processing apparatus 1. The information processing apparatus 1 is realized by, for example, a smartphone, a tablet terminal, a future phone, a personal computer, or the like.

  The information processing apparatus 1 includes a touch panel 2 in which a display device and an input device are combined. For example, the touch panel 2 is configured by providing a transparent sheet-like position input device as an input device on a display screen of a flat panel display as a display device. The touch panel 2 displays an instruction input screen for inputting various instructions and a route map representing connection of nodes such as a station and a bus stop. The information processing apparatus 1 performs processing according to an instruction input by a user's touch operation on the touch panel 2. The information processing apparatus 1 includes a CPU (Central Processing Unit) 11, a RAM (Random Access Memory) 12, a ROM (Read Only Memory) 13, a storage 14, a communication interface 15, and an IO interface 16. These components of the information processing apparatus 1 are connected via a bus B so that they can communicate with each other.

  The CPU 11 controls the operation of the information processing apparatus 1 by reading a computer program from the ROM 13 and executing it using the RAM 12 as a work area. In the present embodiment, the CPU 11 realizes a versatile route map display mode by executing a computer program.

  The storage 14 is a large-capacity auxiliary storage device, and is realized by a hard disk, an SSD (Solid State Drive) or the like. The storage 14 may be an external storage device connected via an interface such as USB (Universal Serial Bus) or a network such as the Internet. The storage 14 stores various data for displaying a route map. The communication interface 15 is a wired or wireless communication device for connecting to a network such as the Internet, a public line, or a LAN (Local Area Network). The IO interface 16 performs interface control with the touch panel 2. An instruction input from the touch panel 2 is transmitted to the CPU 11 by the IO interface 16, and an image or the like is displayed on the touch panel 2 by the CPU 11.

  FIG. 2 is a functional block diagram for displaying a route map on the touch panel 2 in the information processing apparatus 1 having such a configuration. Each function is realized by the CPU 11 executing a computer program and in cooperation with other components. The information processing apparatus 1 functions as a control unit 121, a data acquisition unit 122, a memory 123, and a data storage unit 124.

The control unit 121 performs a process for editing and displaying a route map in accordance with an instruction from the input device 101. In this embodiment, the route instructed by the user is highlighted to facilitate visual recognition. The highlighting means that the portion is in a display mode that can be visually recognized more intuitively than the surrounding display portions. In this embodiment, the relative position relationship between the highlighted portions is displayed by making the route instructed by the user the above display mode while not displaying the surrounding route map but displaying it in a light color. Is intuitively understood.
The data acquisition unit 122 acquires a user instruction from the input device 101 of the touch panel 2. The user instruction includes the name of the route to be displayed or the name of the area where the route to be displayed exists. The memory 123 stores the area (display area) of the display area of the display device 102 of the touch panel 2. Further, the memory 123 classifies and stores data such as various codes to be described later so that only the highlighted route and the surrounding display portion can be partially displayed or output later. .

  The data storage unit 124 is constructed in the storage 14 and stores various data used for editing the route map. When the data classified as described above is stored, the data is stored for each classification. For this purpose, the data storage unit 124 is provided with storage areas for a code storage unit 125, a route map storage unit 126, and a guide information storage unit 127.

  The code storage unit 125 stores a link code, a route code, and a region code. If the classified data exists, the classification code and the like are also stored. The link code is information for uniquely identifying a link connecting nodes representing a station or a bus stop. For example, a link code is assigned to each link in order to identify a link between stations such as a link connecting Tokyo Station and Kanda Station, a link connecting Kanda Station and Ochanomizu Station, and so on. A route constituted by a combination of a plurality of links is identified by the route code. For example, a link between Tokyo Station and Kanda Station, a link between Kanda Station and Ochanomizu Station, etc. can be combined to form a “Chuo Line Rapid” route. The route code is assigned to the route configured as described above. The region where the route exists is identified by the region code. A region code is assigned to each unit region such as a station or bus stop area, a city, a prefecture, or a prefecture. For example, in the case of “Chuo Line Rapid”, a region code is assigned to each region of “Chiyoda Ward”, “Shinjuku Ward”, “Shibuya Ward”, “Nakano Ward”, “Suginami Ward”,. A combination of various codes classified by the classification code is identified.

  For example, the control unit 121 acquires a route network of transportation from an external server through the communication interface 15, and adds a link code, a route name to a node name (station name, bus stop name), a route name, and a region name where the route exists. Assign a code and region code. Then, these codes are stored in the code storage unit 125. The control unit 121 may construct the code storage unit 125 by installing an application program. By specifying the region code, a route name (route code) existing in the region is specified. By specifying the route code, the links and node names (station, bus stop) constituting the route are specified.

  The route map storage unit 126 stores each route map of a plurality of routes existing in each region in association with the route code and the region code. A route map is prepared for each route and region. Links between nodes included in the route map are drawn with lines or bands of a size determined based on geographical location, distance, and station over-density for each display area of the information terminal 30 (display area). It is possible. The route or the route map of the region is specified by the route code or the region code.

  For example, the control unit 121 acquires a route network and a map of a transportation facility from an external server through the communication interface 15, and generates a route map based on a geographical position and a distance based on the map for each route included in the route network. To do. The control unit 121 assigns a route code and a region code to the generated route map and stores them in the route map storage unit 126. The control unit 121 may construct the route map storage unit 126 by installing an application program.

  The guide information storage unit 127 stores guide information for each node or each route name. The guide information is, for example, sightseeing spots around the node or route, recommended information, advertisements, and the like. The guidance information is read out by the control unit 121 as necessary, and is superimposed on the route map.

  The control unit 121 acquires guide information together with a station name, a bus stop name, and a route name from an external server via the input device 101 or the communication interface 15 and stores them in the guide information storage unit 127. The control unit 121 updates the guide information already stored in the guide information storage unit 127 with the guide information acquired from the external server through the communication interface 15. Thereby, the latest guidance information is always provided to the user.

  FIG. 3 is a flowchart showing route map display processing using the information processing apparatus 1 configured as described above. The information processing device 1 starts this process when the user inputs the name of the area or route in which the route map is to be displayed from the input device 101 of the touch panel 2.

  The data acquisition unit 122 acquires a region name or route name input by the user from the input device 101, and transmits the region code or route code assigned to the acquired region name or route name to the control unit 121. The control unit 121 acquires a route code representing a region code or a route name from the data acquisition unit 122 (S11). The control unit 121 confirms the display area of the display device 102 stored in the memory 123 (S12).

  The control unit 121 creates a route map to be displayed on the display device 102 of the touch panel 2 based on the acquired area code or route code and the display area. For this purpose, the control unit 121 first reads a route map related to the acquired area code or route code from the route map storage unit 126 (S13). The read route map is, for example, drawn in a predetermined video memory in a light color whose saturation is equal to or lower than a predetermined saturation and whose lightness is equal to or higher than a predetermined brightness. That is, by drawing all the routes that can be displayed in the display area in a light color, it can be used as a white map of a so-called route map.

  The control unit 121 edits the read route map according to the display area (S14). The control unit 121 draws the links included in the route map with lines or bands having a size determined based on the overdensity of the nodes (stations and bus stops) in the display area. In addition, the control unit 121 highlights only the route (station, bus stop, link) in the designated area or the designated route (station, bus stop, link), and the remaining part of the route map remains light in color. Redraw in memory. In addition, the control part 121 may determine the size of a link based on the operation required time for every link, or the number of links in a display area instead of the overdensity of a node. The control unit 121 partially saves the part of the route map highlighted in the memory 123. For example, the control unit 121 superimposes and draws characters or figures having these names on nodes, links, and routes on the route map.

  The control unit 121 displays the edited route map on the display device 102 (S15). FIG. 4 is an exemplary diagram of a route map displayed on the display device 102. In the example of FIG. 4, in order for the user to input “center line rapid” by the input device 101, the information processing apparatus 1 highlights the input “center line rapid” and displays other routes in a light color. . In addition, when the user inputs “Tokyo Station” and “Shinjuku Station” using the input device 101, the information processing apparatus 1 highlights the input “Tokyo Station” and “Shinjuku Station”.

  Part or all of the displayed route map is drawn as a vector image, and the display mode of the links included in the route map can be changed individually and flexibly according to the purpose of use. Therefore, the control part 121 can change the part drawn by the vector image of a route map at arbitrary timings. In addition, the control unit 121 draws the node name and the route name on the route map using, for example, a web font. Therefore, the display size of the node name and the route name is kept constant even when the route map is enlarged and displayed.

  The control unit 121 may superimpose and display the route guidance information to be displayed on the route map. For example, when a route map is displayed, the user instructs to click a node name or a route name display area of the displayed route map. The content of the click instruction is input from the input device 101. The control unit 121 detects the clicked node name or route name display area from the content of the click instruction, and reads the corresponding guide information from the guide information storage unit 127. The control unit 121 superimposes the read guidance information on the route map and displays it on the display device 102.

  In the above processing, the information processing apparatus 1 can provide the user with the route and the node highlighted in accordance with the user input based on the route map displayed in a light color. At that time, the link is drawn with a line or a band having a size determined based on an over-density of the station according to an actual geographical position, a distance between the stations, and a display area on the display device. Therefore, the user can intuitively recognize the actual geographical position between nodes (between stations, between bus stops, and between stations and bus stops) and the distance between stations. In addition, since the route map displays the connection of routes between a plurality of railway companies and bus companies in an integrated manner, the mutual connection becomes clear.

  Further, since all route maps drawn based on various codes can be used as so-called white maps, the highlighted portion can be individually and flexibly changed according to the purpose of use. Furthermore, since only the portion highlighted by the user and its peripheral portion can be individually stored, it is possible to exclude unnecessary data and use only the necessary portion later.

[Second Embodiment]
Next, a route map display system according to a second embodiment of the present invention will be described. In this embodiment, an example in which the present invention is applied to a network type route search system that enables a route search service for portable information terminals is shown.

  FIG. 5 is an overall configuration diagram of the route search system according to the second embodiment, in which characteristic portions are posted. This route search system includes a route search server 10 connected to a digital network N such as the Internet, and an operation information DB 20 that stores operation information for route search, for example, data such as train diagrams and map information around the station. Consists of. An information terminal 30 such as a smartphone, a tablet terminal, a future phone, or a personal computer can be connected to the digital network N. The information terminals 30 can be directly connected to the digital network N if they have data communication and data processing functions. Unlike the information terminal 1 of the first embodiment, the information terminal 30 functions as an input device and a display device. Then, a search condition for route search is input and a route map representing the route search result is displayed.

[Route search server]
The route search server 10 is a server including a CPU, a RAM, a ROM, a storage, a communication interface, an I / O interface, and the like. The route search server 10 is realized by cooperation between the server body and a computer program. That is, the CPU of the server main body reads the computer program from the ROM and the storage and executes it, thereby causing the server main body to function as the data communication interface 100 and the route search tool 110 and execute information processing for route search. enable.

  The data communication interface 100 enables bidirectional communication with the information terminals 30 having data communication and data processing functions, and provides a hierarchical page screen that can be browsed by these information terminals 30. This hierarchical page screen is for performing a route search Web service, and by specifying a precise route search condition interactively between the system side and the user (user), a condition intended by the user is obtained. Provides an environment for searching for routes. The result of route search can also be displayed on this hierarchical page screen.

  The route search tool 110 has functions of a search condition reception unit 111, a route map display unit 112, and a route search engine 113.

  The search condition receiving unit 111 receives a route search condition including a departure station and a destination station. As for at least one of the departure station and the destination station, what is directly input (designated) by the user may be specified as it is as the route search condition, or specified by presenting and selecting a pre-registered one. Also good. The search condition registered in advance includes, for example, what conditions are used for searching when searching for a route. Such search conditions include “low fare”, “fast time”, “low transfer”, “low walking”, and the like. By adding “less walking” to the search conditions, for example, if there are multiple routes from the departure station to the destination station, and the stations to be transferred differ for each route, it is the shortest walking distance to change at which station It is possible to search for a route in consideration of the above. The search condition reception unit 111 generates a departure station condition from the departure station and a destination station condition from the destination station, and adds entrance / exit and ticket gate usage restriction information and a search condition specified by the user as necessary.

The route search engine 113 repeats the process of including the transfer station as a node constituting the route network of the transportation facility and sequentially linking each node from the departure station to the destination station. Thereby, the route search engine 113 searches for one or a plurality of route candidates according to the route search condition, and sets the best match to the route search condition.
The route search engine 113 is also equipped with a known inference engine. If this inference engine finds that the route will not be realistic during the route search, that is, in the process of pasting the link, it will search for the next candidate node for that route candidate at that time. stop. For example, the search after the next node for the route candidate is stopped when it becomes larger than the threshold value stored in the memory in advance.
The route search engine 113 also calculates the total travel cost from the departure station to the destination station for each of a plurality of route candidates, for example, the total required time from the viewpoint of considering the time as the travel cost. Sort multiple routes in ascending order of required time. Further, when there is an entrance or a ticket gate whose use is restricted in the route, the route candidate is specified after the route is excluded.
The basic function portion of the route search engine 113 can use route search software “Electric Spatial” (registered trademark) provided by the present applicant.

  The route map display unit 112 is the route map display system of the present invention, and creates a route map for displaying the route search result by the route search engine 113 on the display device of the information terminal 30. The route map created by the route map display unit 112 is transmitted via the digital network N by the data communication interface 100 to the information terminal 30 that is the input source of the route search condition.

  FIG. 6 is a functional block diagram of the route map display unit 112. The route map display unit 112 has the functions of the control unit 121, the data acquisition unit 122, the memory 123, and the data storage unit 124 shown in FIG.

  The control unit 121 performs processing for editing and displaying a route map by the route map display unit 112. In the present embodiment, the route obtained as a result of the route search is highlighted in the route map so that the user can easily see the route search result. The data acquisition unit 122 acquires a route search result from the route search engine 113. Further, the data acquisition unit 122 acquires the display area of the display device from the information terminal 30. This is the same as the first embodiment in that only the route map to be highlighted and its peripheral portion can be partially saved.

The data stored in the data storage unit 124 is as described in FIG. The data storage unit 124 includes a code storage unit 125, a route map storage unit 126, and a guide information storage unit 127.
For example, the control unit 121 acquires a route network of transportation from the operation information DB 20, assigns a link code, a route code, and a region code to a station, a bus stop, a route name, and a region where the route is included in the route network. Store in the storage unit 125. For example, the control unit 121 acquires a route network and a map of transportation from the operation information DB 20, and generates a route map based on the geographical position and distance from the map for each route included in the route network. A route code and a region code are assigned to the route map storage unit 126 and stored in the route map storage unit 126. The control unit 121 acquires guide information together with a station name, a bus stop name, and a route name from an input device such as a keyboard (not shown) or an external device via the digital network N, and stores it in the guide information storage unit 127.
The data storage unit 124 may be configured in the operation information DB 20. Further, the classified data described above may be stored on the information terminal 30 side in a form that can be read using a code for identifying them as a key.

  FIG. 7 is a flowchart showing a route search using the route search server 10 having such a configuration and a route map display process showing a search result.

  The route search tool 110 receives the route search conditions including the departure station and the destination station through the search condition reception unit 111 (S21). The search condition receiving unit 111 receives a route search condition transmitted from the data communication interface 100 via the digital network N by the information terminal 30. The route search engine 113 performs route search processing using the operation information DB 20 based on the route search condition received by the search condition reception unit 111 (S22). As a result, a route search result representing the optimum route between the departure station and the destination station that meets the route search conditions is obtained. The route search result includes a route code.

  The route map display unit 112 acquires a route search result from the route search engine 113 by the data acquisition unit 122. In addition, the route map display unit 112 acquires the display area of the information terminal 30 from the information terminal 30 that has transmitted the route search condition by the data acquisition unit 122 (S23). In addition, the route map display unit 112 may acquire the display area at a timing when the search condition is received and store the acquired display area in the memory 123. In this case, the information terminal 30 transmits the route search condition and the display area at a time.

  The control unit 121 of the route map display unit 112 creates a route map to be displayed on the display device of the information terminal 30 based on the route search result and the display area. For this purpose, the control unit 121 first reads a route map related to the route code included in the route search result from the route map storage unit 126 (S24). The control unit 121 edits the read route map according to the display area (S25). The editing contents are the same as the processing in S14 of FIG. The route map display unit 112 displays the edited route map on the information terminal 30 that has transmitted the route search condition (S26). For this purpose, the route map display unit 112 transmits route map data representing the edited route map to the information terminal 30 via the data communication interface 100 and the digital network N. Through the above processing, the route map in which the route that is the route search result is highlighted is displayed on the display device of the information terminal 30.

  In the above processing, the route search result can be presented to the user in an easy-to-understand manner by displaying a route map highlighting the route obtained as a result of the route search. The user can intuitively recognize the geographical position and distance between nodes (between stations, between bus stops, and between station and bus stops) from the route map as a result of the route search. Further, even if the route search result is a route that spans transportation between a plurality of railway companies and bus companies, the connection between the routes is integrated and displayed by the route map, so that the mutual connection becomes clear.

  All route maps drawn based on various codes can be used as so-called white maps, the highlighted part can be individually and flexibly changed according to the purpose of use, and the user can emphasize It is the same as in the first embodiment that only the displayed part and its peripheral part can be saved individually. In the second embodiment, the result of the route search can be highlighted in a manner according to the actual geographical position and the distance between stations.
