Here, the first route search unit 202b may search for the first route that satisfies the route search condition based on the traffic information stored in the traffic information database 206c. For example, the first route search unit 202b searches for the first route satisfying the route search condition using the network data stored in the network database 206a while referring to the traffic information stored in the traffic information database 206c. Also good. As an example, the first route search unit 202b, based on network data, calculates the link cost from the starting point to the destination of the route search condition and spreads the search route to obtain the cumulative value of the link cost. Based on this, an optimal route may be calculated. The search may be performed using a known route search method such as the Dijkstra method or the A * (Aster) search algorithm, and other known service area search methods may be used. In the Dijkstra method, the connected link is sequentially traced from the reference origin position (generally, a node close to the origin position) to reach the next node, and the link cost (distance and The time required for passing the link is integrated, and the search route is expanded until the end condition is reached while managing the link group (search route) to be followed next so as to minimize the link cost. For example, the first route search unit 202b may perform a route search while calculating link costs (required time and the like) in consideration of traffic jam information, delay information, and the like.

  Here, the first route search unit 202b may perform a re-search for the first route at the timing when the influence degree based on the traffic information becomes greater than or equal to a predetermined value in the vehicle route of the first route. The degree of influence may be based on the degree of traffic information update (congestion or traffic closure, increase in degree of congestion, etc.), or may be the influence on the already searched first route (change in required time, etc.). . Furthermore, the first route search unit 202b determines the influence degree based on the history of the current position information included in the route search condition received by the route search condition reception unit 202a and the timetable information stored in the network database 206a. (Delay from regular service) may be calculated. Here, the first route search unit 202b resets the departure point in the case of re-searching the first route based on the route search condition including the updated current position information received by the route search condition reception unit 202a. Alternatively, the current location may be estimated and set based on timetable data included in the network data of the first route searched earlier.

As an example, when the vehicle route searched by the first route search unit 202b is a bus route, the second route search unit 202c displays node data representing a bus stop of the route network data of the search result of the first route. Based on the above, the second route may be searched by setting a part of the vehicle route as a bus stop. Since the search method is the same as that of the first route search unit 202b, the description thereof is omitted. In addition, the second route search unit 202c may search for the second route at the timing when the influence degree based on the traffic information becomes greater than or equal to a predetermined value in the vehicle route of the first route. For example, the second route search unit 202c detects traffic congestion on the vehicle route of the first route based on the traffic information, and at the timing when the influence degree (increased required time, etc.) due to the traffic congestion exceeds a predetermined value, The second route may be searched.

Here, the route guidance information generation unit 102e is configured to select a route (first route or second route) selected by the user via the input unit 116 based on the comparison information output by the comparison information output unit 102d. Route guidance information may be generated. Note that the route guidance information generation unit 102e may generate route guidance information for the guidance route based on the guidance information stored in the guidance database 106a.

  The route guidance unit 102f is route guidance means for performing route guidance based on the route guidance information generated by the route guidance information generation unit 102e. For example, the route guidance unit 102f may execute voice guidance and display guidance based on route guidance information for the guidance route. In addition, when performing route guidance, the route guidance unit 102f causes the output unit 114 to display display information such as route information, map information, and / or TBT included in the guidance information included in the route guidance information. May be. Further, the route guide unit 102f may further output the current position information updated by the current position information acquisition unit 102a to the output unit 114. For example, the route guidance unit 102f causes the output unit 114 to display the route information included in the route guidance information and / or the current location of the user of the terminal device 100 on the map information included in the route guidance information. May be. In addition, the route guidance unit 102f outputs, to the output unit 114, voice information corresponding to the display screen (such as voice guidance information associated with a traveling direction at a branch point on the guidance route included in the route guidance information). May be.

  Above, description of an example of a structure of the comparison information provision system in 1st Embodiment is finished.

[Processing of comparison information provision system]
Next, processing of the comparison information providing system according to the first embodiment configured as described above will be described in detail with reference to FIGS.

[Basic processing]
First, an example of the basic processing of the comparison information providing system in the first embodiment will be described below with reference to FIGS. FIG. 2 is a flowchart showing an example of basic processing of the comparison information providing system in the first embodiment.

  As shown in FIG. 2, first, the route search condition transmitting unit 102b of the terminal device 100 sets a route search condition (step SA-1). For example, the route search condition transmission unit 102b may set a route search condition including at least a departure place and a destination. Note that the route search condition transmission unit 102b may set the current position based on the current position information acquired by the current position information acquisition unit 102a as the departure point of the route search condition. Further, the route search condition may further include a transit point, moving means, departure time, transit time, arrival time, and / or date. Here, the departure time may be the current time. Note that the route search condition transmission unit 102b may cause the user to input route search conditions via the input unit 116 of the terminal device 100.

  Then, the route search condition transmission unit 102b of the terminal device 100 transmits the set route search condition to the server device 200 (step SA-2). Even after this processing, the route search condition transmitting unit 102b may transmit the route search condition including the updated current position information to the server device 200 periodically or every update.

  Then, the route search condition receiving unit 202a of the server device 200 receives the route search condition transmitted from the terminal device 100 (step SA-3).

  Then, the first route search unit 202b of the server device 200 includes a vehicle route that satisfies the route search condition received by the route search condition reception unit 202a based on the network data stored in the network database 206a. (Step SA-4). For example, the first route search unit 202b may search for a first route including the bus route as the vehicle route based on the bus route network data stored in the network database 206a.

  And the 2nd route search part 202c of the server apparatus 200 is based on the network data memorize | stored in the network database 206a, and in the predetermined area from the one part location of the vehicle route searched by the 1st route search part 202b, A second route using a moving means other than the vehicle is searched (step SA-5). For example, the second route searching unit 202c uses the second route for walking by using network data (for example, road network data) of other moving means other than the bus route network data by the first route searching unit 202b. May be searched. Here, the second route search unit 202c sets a predetermined section from a part of the vehicle route (such as a bus stop) to the arrival point of the vehicle route (such as a bus stop that provides guidance for getting off on the first route). Two routes may be searched. In addition, the second route search unit 202c may search for the second route with a predetermined section from a part of the vehicle route (such as a bus stop) to the destination of the route search condition. As an example, when the vehicle route searched by the first route search unit 202b is a bus route, the second route search unit 202c displays node data indicating a bus stop in the route network data of the search result of the first route. Based on the above, the second route may be searched by setting the bus stop as a part of the vehicle route. Note that the first route search unit 202b may search for the second route at a timing when the degree of influence based on traffic information in the vehicle route of the first route becomes greater than or equal to a predetermined value. Here, FIG. 3 is a diagram schematically illustrating an example of a first route including a bus route and a second route including a walking route. R1 represents the first route, R2 represents the second route, and BS0 to BS4 represent bus stops.

  As illustrated in FIG. 3, when the first route search unit 202b searches for a first route including a bus route passing through the bus stops BS0 to BS4, the second route search unit 202c may select a part of the bus route. The second route from the bus stop BS1 to the destination station is searched. In this example, the route from only the bus stop BS1 is shown. However, the second route search unit 202c may search for candidates for the second route from each bus stop BS0 to BS3 to the destination (station). Of course, an appropriate candidate may be selected as the second route based on the link cost such as the required time. Further, as shown as a traffic jam section in FIG. 3, the second route search unit 202c searches for the second route at a timing when the influence degree becomes a predetermined level or more, such as when a traffic jam occurs in a bus zone on the first route. May be. In that case, the 1st route search part 202b may perform a re-search of the 1st route in consideration of traffic jam.

  Returning to FIG. 2 again, the comparison information generation unit 202d of the server device 200 can compare the first route searched by the first route search unit 202b and the second route searched by the second route search unit 202c. The comparison information is generated (step SA-6). The comparison information generation unit 202d is calculated as the link cost by the first route search unit 202b and the second route search unit 202c, as well as the time required for each route, the travel distance, the charge, the congestion level, and the discomfort level. Further, comparison parameters such as a user preference suitability degree and a weather influence degree may be calculated. For example, the first route search unit 202b may calculate a fee based on the use fare fee data stored in the network database 206a, and may calculate the congestion degree (postpay) based on the congestion degree data stored in the traffic information database 206c. In this case, the waiting time or the like) and the degree of discomfort (such as a delay from the timetable) may be calculated. Further, the first route search unit 202b may calculate the user preference suitability level based on the POI information stored in the map database 206b depending on whether there is a POI on the route that matches the user preference. Good. Further, the first route search unit 202b may calculate a weather influence degree (such as an index to be wet with rain) based on weather information downloaded from an external device 600 (a server such as the Japan Meteorological Agency or a private weather service). Then, the comparison information generation unit 202d may generate, as comparison information, information that presents the comparison parameter calculated in this manner so that the comparison parameter can be compared between the first route and the second route. Further, the comparison information generated by the comparison information generation unit 202d may be information obtained by graphing the first route and the second route so that they can be compared.

  Then, the comparison information transmission unit 202e of the server device 200 transmits the comparison information generated by the comparison information generation unit 202d to the terminal device 100 (Step SA-7).

  Then, the comparison information receiving unit 102c of the terminal device 100 receives the comparison information transmitted from the server device 200 (step SA-8). Here, the comparison information receiving unit 102 c may store the comparison information and route information in the storage unit 106.

  Then, the comparison information output unit 102d of the terminal device 100 outputs the comparison information received by the comparison information receiving unit 102c to the output unit 114 (step SA-9).

  The above is an example of the basic processing of the comparison information providing system in the first embodiment. When a route is selected by the user via the input unit 116 after the comparison information is output, the route guidance information generation unit 102e stores the route as the guidance route in the guidance database 106a. The route guidance information for the guidance route may be generated based on the guidance information, and the route guidance unit 102f may perform the route guidance based on the generated route guidance information.

[Timing control processing]
Next, an example of the timing control process in the basic process of the comparison information providing system in the first embodiment described above will be described below with reference to FIGS. Here, FIG. 4 is a flowchart illustrating an example of timing control processing of the server device 200 in the comparison information providing system of the first embodiment. In this timing control process, the second route is not searched following the search for the first route, but at the timing when the influence degree becomes a predetermined level or more, such as when a traffic jam occurs on the first route. Will be described in detail.

  As shown in FIG. 4, the first route search unit 202b includes a vehicle route that satisfies the route search condition based on the network data stored in the network database 206a, as in step SA-4 described above. A route is searched (step SB-1). Note that the first route search unit 202b may generate a combination of link data indicating the searched first route as route information, and an image in which the first route is superimposed on the map data stored in the map database 206b. Data or the like may be generated as route information. Here, FIG. 5 is a diagram illustrating a display example of search information of the first route searched by the first route search unit 202b.

  As shown in FIG. 5, in this example, when a route search condition is set in which the departure place is “A Athletic Field” and the destination is “D Station”, the first route search unit 202b generates The route information of one route is shown. As shown in the figure, the first route includes a bus stop “in front of A athletic field” to a bus stop “B station west exit” as a vehicle route. Note that MA-1 is a warning icon indicating the occurrence of a traffic jam and the like, and is not initially displayed. However, as will be described later, MA-1 is displayed when a notification is received from the server device 200 based on traffic information update or the like.

  Returning to FIG. 4 again, the comparison information transmission unit 202e transmits the route information of the first route searched by the first route search unit 202b to the terminal device 100, whereby the first route is sent to the output unit 114 of the terminal device 100. Is output (step SB-2). For example, the terminal device 100 generates route guidance information based on the route information of the first route by the processing of the route guidance information generation unit 102e, and executes the route guidance of the first route by the processing of the route guidance unit 102f. Also good.

  Then, the second route search unit 202c determines whether or not a traffic jam has occurred on the first route based on traffic information such as traffic jam information updated by the traffic information acquisition unit 202f (step SB-3). . Here, FIG. 6 is a diagram showing a traffic jam section that occurs on the vehicle route of the first route. BS10 to BS14 indicate the bus stops before the bus stop “B station west exit” at the arrival place on the bus vehicle route.

  As shown in FIG. 6, when the arrival place “B station west exit” of the vehicle route is a rotary in front of the station, traffic congestion is likely to occur frequently. In that case, it may be quicker to get off at the bus stop in front (for example, the bus stop BS14) and walk to the B station rather than continue to take the bus to the arrival stop. In particular, when there is a possibility that the user will miss the train on the first route that was initially searched, such information is required. Therefore, the second route search unit 202c determines the timing for searching for the second route to get off at a part of the vehicle route. Note that the second route search unit 202c is not limited to determining the occurrence of traffic congestion on the first route, and the second route search unit 202c determines whether or not the degree of influence based on traffic information or the like in the vehicle route of the first route is greater than or equal to a predetermined value. You may judge. For example, the degree of influence may be based on the degree of traffic information update (congestion or traffic closure, increase in congestion, etc.), and is an influence on the already searched first route (change in required time, etc.) Also good. As an example, the first route search unit 202b performs a regular search based on the history of the current position information included in the route search condition received by the route search condition reception unit 202a and the timetable information stored in the network database 206a. The delay from the operation may be calculated as the degree of influence.

  Returning to FIG. 4 again, when the second route search unit 202c determines that a traffic jam has occurred (Yes in step SB-3), the second route search unit 202c sets a predetermined section for searching for the second route and comparing with the first route. (Step SB-4). As an example, the starting point of the predetermined section is a part of the vehicle route, the current position based on the current position information received and updated by the route search condition reception unit 202a, the guidance point, and the current position on the traveling direction side. Each stop position such as a certain station or bus stop may be used. A plurality of predetermined sections may be set so that the user can select where to get on and where to get off. In addition, the end point of the predetermined section may be the arrival point of the vehicle route, the destination or waypoint of the entire route set in the route search condition, or a transfer station. As an example, when the vehicle route searched by the first route search unit 202b is a bus route, the second route search unit 202c displays node data representing a bus stop of the route network data of the search result of the first route. Based on the above, a bus stop on the vehicle route may be set as the starting point of the predetermined section. These predetermined sections may be defined in advance in the server device 200 or may be defined in the route search condition. At the timing of step SB-4, the comparison information transmission unit 202e may transmit notification information for notifying that a traffic jam has occurred to the terminal device 100. Thereby, as an example, the comparison information output unit 102d of the terminal device 100 displays the warning icon MA-1 indicating the occurrence of the traffic jam illustrated in FIG. Note that if the second route search unit 202c determines that no congestion has occurred even after a predetermined time has elapsed (for example, the arrival time of the first route to the arrival point of the vehicle route) (step SB). -3, No), and finishes the timing control process.

  Then, the second route search unit 202c searches for the second route using the moving means other than the bus in the set predetermined section based on the network data stored in the network database 206a (step SB-5). . At that time, the first route search unit 202b performs a re-search of the first route. Here, the first route search unit 202b resets the departure point in the case of re-searching the first route based on the route search condition including the updated current position information received by the route search condition reception unit 202a. May be. In addition, the first route search unit 202b updates the first route satisfying the route search condition including the updated departure place with the latest traffic information updated by the traffic information acquisition unit 202f (running before the bus being boarded). A search may be made with reference to network history stored in the network database 206a and the travel history of the bus that is present, traffic jam prediction information, and the like. For example, the first route search unit 202b may perform a route search for the first route while calculating link cost (required time, etc.) in consideration of traffic jam information, delay information, and the like.

  Then, the comparison information generation unit 202d calculates the required time based on the first route and the second route searched by the first route search unit 202b and the second route search unit 202c (step SB-6). For example, the comparison information generation unit 202d may obtain the required time by dividing the moving distance based on the route by the average speed of the moving means. When the required time is calculated as the link cost by the first route searching unit 202b and the second route searching unit 202c during the route search, the comparison information generating unit 202d acquires information on the required time as the route search result.

  Then, the comparison information generation unit 202d generates comparison information that enables comparison between the first route re-searched by the first route search unit 202b and the second route searched by the second route search unit 202c. (Step SB-7). Here, FIG. 7 is a diagram illustrating an example of comparison information generated by the comparison information generation unit 202d.

  As shown in FIG. 7, the comparison information generated by the comparison information generating unit 202d is, for example, getting off at the bus stops BS10 to BS14 in front of the bus stop “B station west exit” at the arrival point on the bus vehicle route and walking. This is information for displaying the required time of the second route traveling in step (b) and the required time of the first route that continues to ride on the bus side by side for comparison. Here, as shown in the figure, the comparison information generation unit 202d generates comparison information for comparing the first route and the second route and highlighting the shorter required time with bold characters or surrounding characters. May be. In addition, the comparison information generation unit 202d may generate comparison information that displays the fare in the case where the user continues to get on the bus in a comparable manner. Further, as indicated by the dashed arrows, a traffic jam section on the bus route may be clearly indicated. Here, FIG. 8 is a diagram illustrating an example of comparison information in a graph format generated by the comparison information generation unit 202d.

  As shown in FIG. 8, the comparison information generation unit 202d graphed the comparison parameters such as the required time for the first route and the comparison parameters such as the required time for the second route so that they can be easily compared visually. Comparison information may be generated. For example, as shown in the figure, the comparison information generation unit 202d is a graph in which the required time is plotted on the vertical axis and the stop position from the bus stop BS10, which is a part of the first route, to the bus stop “B Station West Exit” is plotted on the horizontal axis. May be generated as comparison information. As shown in FIG. 8, in this example, if you get off and walk at the bus stop BS13 and the bus stop BS14, it takes a shorter time than going to the bus stop “B station west exit” and getting on quickly. I can grasp. Here, FIG. 9 is a diagram illustrating an example of comparison information of a route search result to the destination for the first route and the second route.

  As shown in FIG. 9, in this example, the comparison information generating unit 202d includes a plurality of getting-off candidate bus stops BS to the destination when getting off at the recommended bus stop BS14 based on the required time or the like. Comparison information may be generated that displays the two routes so as to be comparable to the original first route. If it displays in this way, the train (12 o'clock) that is earlier than the train (12:30 departure) that is scheduled to board the first route on the first route, as soon as you get off at the B station of the train boarding station because you got off at the bus stop on the way 25 minutes) and can prompt the user to arrive at the destination (station D) as soon as possible.

  Returning to FIG. 4 again, the comparison information transmission unit 202e transmits the comparison information generated by the comparison information generation unit 202d as described above to the terminal device 100 (step SB-8). Here, the comparison information transmission unit 202e receives the comparison information when receiving a comparison information transmission request transmitted from the terminal device 100 when the user presses the warning icon MA-1 via the input unit 116. You may transmit to the terminal device 100.

  The above is an example of the timing control process of the comparison information providing system in the first embodiment.

[Simulation function]
Subsequently, as an example of the comparison information generated in the processing of the comparison information providing system in the first embodiment described above, the case where the first route is advanced and the case where the second route is advanced can be compared on the map. An example of simulation will be described with reference to FIG. In other words, in this simulation example, icons that travel on the first route and icons that travel on the second route are displayed on a map in a time series to provide comparative information that is easy for the user to grasp dynamically. To do. Here, FIG. 10 is a diagram illustrating a display example of comparison information for executing the simulation. The solid line arrow represents the first path, and the broken line arrow represents the second path.

  As shown in FIG. 10, the comparison information generating unit 202d performs a simulation on the map so that the case of traveling the first route and the case of traveling the second route can be compared. Comparison information such as moving image data for displaying the icon representing the moving body moving forward and the icon representing the moving body moving along the second route at the same time along the time axis is generated. MA-15 in FIG. 10 is a playback button, and when pressed via the input unit 116, a bus icon MA-13, character icons MA-10 to MA-12, and a train icon MA-14 are displayed on the map. Move and stop when the stop button MA-16 is pressed.

  At this time, it is configured to move in time series, and when the bus icon MA-13 passes the bus stop BS20 on the first route, the character icon MA-10 appears in the vicinity of the bus stop BS20 accordingly, and E station It starts moving at walking speed towards. Similarly, when the bus icon MA-13 passes the bus stop BS21 on the first route, the character icon MA-11 appears and moves near the bus stop BS21, and when the bus icon BS-12 passes the bus stop BS22, the character icon MA-12 appears near the bus stop BS22. Move towards E station. As a result, the user visually grasps which is faster when he gets on the bus to E station and gets off at each of the bus stops BS20 to BS22 on the way to E station. can do. In the case of a vehicle such as a private car as well as a bus, the comparison information generation unit 202d may generate comparison information so that the walking character starts to move before and after a traffic jam or at the timing of passing a traffic light. Further, as illustrated in FIG. 10, the comparison information generation unit 202d may generate comparison information in which a balloon display indicating a required time is superimposed.

  Above, description of the process of the comparison information provision system in 1st Embodiment is finished.

  Here, in the above-described example, the case where the route search of the second route in the predetermined section is executed when the traffic jam occurs is not limited to this, but the second route search unit 202c arrives at the bus stop every predetermined time. The second route may be searched at another timing such as the timing of the above. This is because the bus section can be delayed due to a large number of passengers at the bus stop even if there is no traffic jam.

  In the above example, the example of comparing the predetermined time when using the bus with the predetermined time when using the walk has been described in particular. However, the present invention is not limited to this. Information such as whether it is necessary to do so may be included in the comparison information. Further, display control such as highlighting of comparison information may be performed according to the user history of the user, user attributes, and the like.

  As described above, according to the present embodiment, the user appropriately determines whether to continue using the current moving means or to move using another moving means on the route to the same destination. The information you get can be provided. In particular, bus operation is subject to uncertainties, so the situation tends to fluctuate. One of the uncertainties is that it is easily influenced by the weather, and when it rains, the number of users increases more than on a clear day, and it takes time to get on and off due to folding of an umbrella or the like. In addition, it is easily affected by the situation of traffic, and when traffic jams occur due to events, road construction, accidents, etc., it is easy to get involved suddenly. In addition, even if it is operated according to the timetable, there are routes that pass through a narrow shopping street in front of the station, and repeatedly turn right and left while getting caught in the traffic light, and the distance between the bus stops is so far away Since there are many walking distances without any problems, it is faster to get off at the bus stop in front of the station. The present embodiment has been developed to overcome the uncertain factors as described above. The bus route is not limited to the timetable, and is considered as a second factor in consideration of various factors such as weather and road conditions. Since the route is presented so as to be comparable to the first route, it is possible to provide information that can be appropriately determined to the user.

[Second Embodiment]
Next, a second embodiment of the present invention (comparison information providing apparatus 400 (stand-alone type)) will be described with reference to FIGS. 11 and 12. Here, FIG. 11 is a block diagram showing an example of the configuration of the comparison information providing apparatus 400 in the second embodiment, and conceptually shows only the part related to the present invention in the configuration.

  In the second embodiment, all functions are collected in the comparison information providing apparatus 400, and a first route including a vehicle route that satisfies a route search condition is searched based on network data that defines a traffic network. Based on the network data, a second route using a moving means other than the vehicle in a predetermined section from a part of the vehicle route is searched, and the first route and the second route can be compared. It has a function of generating and outputting comparison information. As described above, the second embodiment is different from the other embodiments in that the comparison information providing apparatus 400 is configured as a stand-alone type and performs processing alone.

[Configuration of comparison information providing apparatus 400 (stand-alone type)]
First, an example of the configuration of the comparison information providing apparatus 400 (stand-alone type) in the second embodiment will be described with reference to FIG.

  As illustrated in FIG. 11, the comparison information providing apparatus 400 according to the second exemplary embodiment of the present invention includes a position acquisition unit 412, an output unit 414, an input unit 416, a control unit 402, and a storage unit 406. Each unit of the comparison information providing apparatus 400 may be communicably connected via an arbitrary communication path. The comparison information providing apparatus 400 is, for example, various navigation terminals such as PND (Portable Navigation Device) and WND (Wireless Navigation Device), various information processing apparatuses such as notebook personal computers, or mobile phones, PHS, PDAs and the like. It may be a mobile terminal device or the like. Further, the comparison information providing apparatus 400 may be connected to the external device 600 so as to be able to communicate with each other via the network 300 via the communication control interface unit 404.

  In FIG. 11, the functions of the input / output control interface unit 408, the position acquisition unit 412, the output unit 414, and the input unit 416 are the same as those in the first embodiment and the second embodiment, and thus description thereof is omitted. . Further, each part of the storage unit 406 (network database 406a, map database 406b, traffic information database 406c, guidance database 406d, etc.) is also provided in the comparison information providing apparatus 400, not the server apparatus 200, Since each function is the same as that of the first embodiment and the second embodiment, description thereof is omitted.

  In addition, as for each part of the control unit 402, each function is the same as that of the first embodiment except that the comparison information providing apparatus 400 of the present embodiment is a stand-alone type and the control unit 402 does not include each transmission / reception unit. Basically the same.

  In FIG. 11, the control unit 402 has an internal memory for storing a control program such as an OS, a program defining various processing procedures, and necessary data. And the control part 402 performs the information processing for performing various processes with these programs. The control unit 402 is functionally conceptually configured as a current position information acquisition unit 402a, a route search condition setting unit 402b, a first route search unit 402c, a second route search unit 402d, a comparison information generation unit 402e, a comparison information output unit 402f, A traffic information acquisition unit 402g, a route guidance information generation unit 402h, and a route guidance unit 402j are provided. Among these, the functions of the second route search unit 402d, the comparison information generation unit 402e, the traffic information acquisition unit 402g, the route guidance information generation unit 402h, and the route guidance unit 402j are the same as those in the first embodiment, and will be described. Is omitted.

  Among these, the current position information acquisition unit 402 a is a current position information acquisition unit that acquires the current position information of the user of the comparison information providing apparatus 400. Here, the current position information acquisition unit 402a may acquire the current position information of the user of the comparison information providing apparatus 400 at every predetermined period (for example, every 1 second or every 3 minutes). Further, the current position information acquisition unit 402a may acquire the position information calculated from the position information signal received from the position transmission device 500 by the position acquisition unit 412 as the current position information of the user of the comparison information providing device 400. .

  Also, the current position information acquisition unit 402a may acquire position information such as position coordinates about the current position input by the user via the input unit 416 as the current position information of the user of the comparison information providing apparatus 400. Good. Here, the current position based on the current position information input by the user via the input unit 416 may be a position where the user actually exists, or a virtual current position arbitrarily selected by the user. (As an example, it may be an arbitrary point such as an Osaka station or airport selected by a user in Tokyo). For example, the current position information acquisition unit 402a is designated on the display screen based on the map information displayed on the output unit 414 by the user via the input unit 416 (for example, designation operation on the touch panel type output unit 414). The coordinates obtained may be acquired as the current position information of the user of the comparison information providing apparatus 400.

  The route search condition setting unit 402b is route search condition setting means for setting route search conditions. Here, the route search condition may be a route search condition including at least a departure place and a destination. The departure point of the route search condition may be the current location of the user of the comparison information providing apparatus 400 based on the current location information updated by the current location information acquisition unit 402a. Here, the route search condition setting unit 402b may periodically acquire route search conditions including updated current position information and reset the departure place. Further, the route search condition may further include a transit point, moving means, departure time, transit time, arrival time, and / or date. Here, the departure time may be the current time. The route search condition setting unit 402b may cause the user to input these route search conditions via the input unit 416.

  The first route search unit 402c searches for a route that satisfies the route search condition received by the route search condition setting unit 402b by using the network data stored in the network database 406a, and the searched route is the first route. As a first route search means. In the present embodiment, the first route search unit 402c searches for a route including the vehicle route as the first route. Here, the first route search unit 402c may search for the first route that satisfies the route search condition based on the traffic information stored in the traffic information database 406c. For example, the first route search unit 402c searches for the first route satisfying the route search condition using the network data stored in the network database 406a while referring to the traffic information stored in the traffic information database 406c. Also good. As an example, the first route search unit 402c, based on the network data, spreads the search route from the starting point to the destination of the route search condition while calculating the link cost, thereby obtaining the accumulated link cost. Based on this, an optimal route may be calculated. The search may be performed using a known route search method such as the Dijkstra method or the A * (Aster) search algorithm, and other known service area search methods may be used. In the Dijkstra method, the connected link is sequentially traced from the reference origin position (generally, a node close to the origin position) to reach the next node, and the link cost (distance and The time required for passing the link is integrated, and the search route is expanded until the end condition is reached while managing the link group (search route) to be followed next so as to minimize the link cost. For example, the first route search unit 402c may perform a route search while calculating link costs (required time and the like) in consideration of traffic jam information, delay information, and the like.

  Here, the first route search unit 402c may re-search for the first route at the timing when the influence degree based on the traffic information becomes greater than or equal to a predetermined value in the vehicle route of the first route. The degree of influence may be based on the degree of traffic information update (congestion or traffic closure, increase in degree of congestion, etc.), or may be the influence on the already searched first route (change in required time, etc.). . Further, the first route search unit 402c determines the influence degree based on the history of the current position information included in the route search condition set by the route search condition setting unit 402b and the timetable information stored in the network database 406a. (Delay from regular service) may be calculated. Here, the first route search unit 402c may reset the departure point in the case of re-searching the first route based on the current position information updated by the current position information acquisition unit 402a. The present location may be estimated and set based on timetable data included in the network data of the first route. Here, the first route search unit 402c may search for the first route including the bus route as the vehicle route based on the bus route network data stored in the network database 406a. In this case, the first route search unit 402c may calculate the time required for regular operation based on the timetable data included in the route network data, but the traffic information stored in the traffic information database 406c. For example, when it is determined that a regular operation is not performed, the required time may be calculated in consideration of traffic information. The route information may be a combination of link data indicating the searched route, and may include route position information, image data indicating the route (for example, a polyline), and the like.

  The comparison information output unit 402f is a comparison information output unit that outputs the comparison information received by the comparison information generation unit 402e to the output unit 414. For example, the comparison information output unit 402e may perform display or audio output via the output unit 414 based on the comparison information received by the comparison information generation unit 402e.

  Above, description of an example of a structure of the comparison information provision apparatus 400 in 2nd Embodiment is finished.

[Processing of comparison information providing apparatus 400 (stand-alone type)]
Next, an example of the process of the comparison information providing apparatus 400 according to the second embodiment configured as described above will be described in detail with reference to FIG. FIG. 12 is a flowchart illustrating an example of processing of the comparison information providing apparatus 400 according to the second embodiment. In addition, about the description similar to 1st Embodiment mentioned above, it may abbreviate | omit.

  As shown in FIG. 12, first, the route search condition setting unit 402b sets route search conditions (step SC-1). For example, the route search condition setting unit 402b may set a route search condition including at least a departure place and a destination. Note that the route search condition setting unit 402b may set the current position based on the current position information acquired by the current position information acquisition unit 402a as the departure point of the route search condition. Further, the route search condition may further include a transit point, moving means, departure time, transit time, arrival time, and / or date. Here, the departure time may be the current time. Note that the route search condition setting unit 402b may cause the user to input route search conditions via the input unit 416.

  Then, the first route search unit 402c searches for a first route including a vehicle route that satisfies the route search condition received by the route search condition setting unit 402b based on the network data stored in the network database 406a ( Step SC-2). For example, the first route search unit 402c may search for the first route including the bus route as the vehicle route based on the bus route network data stored in the network database 406a.

  Then, the second route search unit 402d is based on the network data stored in the network database 406a and other than the vehicle in a predetermined section from a part of the vehicle route searched by the first route search unit 402c. The second route using the moving means is searched (step SC-3). For example, the second route searching unit 402d uses the network data (for example, road network data) of other moving means other than the bus route network data by the first route searching unit 402c to use the second route for walking. May be searched. Here, the second route search unit 402d sets a predetermined section from a part of the vehicle route (such as a bus stop) to an arrival point of the vehicle route (such as a bus stop that provides guidance for getting off on the first route). Two routes may be searched. In addition, the second route search unit 402d may search for the second route with a predetermined section from a part of the vehicle route (such as a bus stop) to the destination of the route search condition. As an example, when the vehicle route searched by the first route search unit 402c is a bus route, the second route search unit 402d displays node data representing a bus stop in the route network data of the search result of the first route. Based on the above, the second route may be searched by setting the bus stop as a part of the vehicle route. Note that the first route search unit 402c may search for the second route at the timing when the degree of influence based on traffic information in the vehicle route of the first route becomes greater than or equal to a predetermined value. In that case, the 1st route search part 402c may perform a re-search of the 1st route based on traffic information, such as traffic jam.

  Then, the comparison information generation unit 402e generates comparison information that makes it possible to compare the first route searched by the first route search unit 402c and the second route searched by the second route search unit 402d ( Step SC-4). Note that the comparison information generation unit 402e is calculated as the link cost by the first route search unit 402c and the second route search unit 402d, as well as the time required for each route, the travel distance, the charge, the congestion level, and the discomfort level. Further, comparison parameters such as a user preference suitability degree and a weather influence degree may be calculated. For example, the first route search unit 402c may calculate a fee based on the use fare fee data stored in the network database 406a, and may calculate the congestion degree (postpayment) based on the congestion degree data stored in the traffic information database 406c. In this case, the waiting time or the like) and the degree of discomfort (such as a delay from the timetable) may be calculated. Also, the first route search unit 402c may calculate the user preference suitability level based on the POI information stored in the map database 406b depending on whether there is a POI on the route that matches the user preference. Good. In addition, the first route search unit 402c may calculate a weather influence level (such as an index to get wet with rain) based on weather information downloaded from an external device 600 (a server such as the Japan Meteorological Agency or a private weather service). Then, the comparison information generation unit 402e may generate, as comparison information, information that presents the comparison parameter calculated in this manner so that the comparison parameter can be compared between the first route and the second route. Further, the comparison information generated by the comparison information generation unit 402e may be information obtained by graphing the first route and the second route so that they can be compared.

  Then, the comparison information output unit 402f outputs the comparison information generated by the comparison information generation unit 402e to the output unit 414 (Step SC-5).

  The above is an example of the process of the comparison information providing apparatus 400 in the second embodiment. When a route is selected by the user via the input unit 416 after the comparison information is output, the route guidance information generation unit 402h stores the route as the guidance route and is stored in the guidance database 406a. Based on the guidance information, route guidance information for the guidance route may be generated, and the route guidance unit 402j may perform route guidance based on the generated route guidance information. In addition, the comparison information providing apparatus 400 may execute the timing control process using the above-described process as a basic process, and generate comparison information having a simulation function, as in the first embodiment.

  Above, description of an example of the process of the comparison information provision apparatus 400 in 2nd Embodiment is finished.
