  The present invention relates to a route information distribution system in which a terminal device distributes to a terminal device traffic information relating to a guide route including a route section using a transportation from an arbitrary departure point to a destination acquired from a route information guide server or the like. In particular, the information on the guide route and the information on the traffic information distribution destination are registered in the route information guide server from the terminal device, and the route information guide server is based on the information on the guide route registered, The present invention relates to a route information distribution system that discriminates a time zone in which traffic information related to the guidance route is distributed and distributes traffic information related to the guidance route in that time zone only to the registered distribution destination.

  2. Description of the Related Art Conventionally, navigation devices and navigation systems that guide a user by searching for a route from a desired departure point to a destination using map data and road data are known. Such navigation devices and navigation systems are known. As a car navigation device that is installed in an automobile and guides the route to the driver, a communication type that uses a mobile phone as a navigation terminal to send a route search request to the route search server, receives the result, and receives route guidance Navigation systems have been put to practical use.

  In particular, the communication-type navigation system is a system that uses a mobile terminal such as a mobile phone as a navigation terminal, and is also used as a navigation system for pedestrians. As a navigation system for pedestrians, it is preferable to add a route guidance function including transportation, and in addition to searching and guidance for walking routes, the route search server accumulates routes and operation time data of transportation, There is also a navigation system having a function of guiding a route from a desired departure station to a desired destination station (boarding candidate train) in addition to searching for a walking route and guidance. There is also a traffic guidance system that receives and displays information such as routes, timetables of transportation facilities, and trains that can be boarded from an information distribution server without searching for walking routes.

  A general navigation device, a route search device and a route search method used in a communication navigation system are disclosed in, for example, the following Patent Document 1 (Japanese Patent Laid-Open No. 2001-165681). This navigation system is configured to send information on a departure point and a destination from a portable navigation terminal to an information distribution server, and the information distribution server searches and guides a route that matches a search condition from road network and traffic network data. Has been. As the search condition, there are means for moving from the departure place to the destination, for example, walking, automobile, combined use of railroad and walking, and the route is searched as one of the search conditions.

  The information distribution server has roads (routes) of map data as nodes and nodes as the positions of inflection points, links connecting the nodes as links, and cost information (distance and required time) of all links as a database. ing. Then, the information distribution server sequentially searches for a link from the departure node to the destination node with reference to the database, and traces the node and link with the smallest cost information of the link as a guide route. The shortest route can be guided to the portable navigation terminal. As such a route search method, a method called label determination method or Dijkstra method is used. Patent Document 1 also discloses a route search method using this Dijkstra method.

  A route search system that searches for routes that use transportation is a database of operation time data of each transportation based on route search conditions such as departure date, departure location, destination, arrival time specified by the user. It has a time database and data that makes the traffic network a database based on this. Then, referring to these databases, each available means of transportation (individual trains and route buses) connecting the departure point and destination, including connections (transfers), is sequentially traced to meet the route search conditions. It is configured to present one or a plurality of candidates for a guide route (departure station, destination station, route, train, etc.). As route search conditions, it is generally possible to specify conditions such as required time, number of transfers, and fares.

  In addition, as a system for conducting searches and guidance related to transportation facilities, a terminal device such as a mobile phone is connected to an information distribution server for guiding route information and timetable information of transportation facilities, and a desired departure station, departure time, destination station, etc. There is also provided a guidance system that can specify information, receive information on routes, trains, trains and other transportation means that can be boarded, and display them on a terminal device. In general, when such use is performed from a terminal device, address information such as a URL (Uniform Resource Locator) or a domain name for specifying a location where information to be downloaded exists is input to the terminal device and specified by the address. The information distribution server (information site) is accessed to download desired information.

  The route search data in the navigation system for route search and route guidance using the transportation system is the same as the road network data in the in-vehicle navigation system and the pedestrian navigation system. In addition to data networked as a two-way link, the operation time and required time of each link are added as link cost data for each means of transportation operated on each traffic route. Furthermore, there is a system in which fare data is added and the fare of the searched guide route is guided together.

  In route search using transportation facilities, there is a problem of a margin time of a route and a delay of transportation means such as a train with respect to a desired arrival time at a destination. In particular, in transportation means such as trains, there are delays due to weather and congestion in addition to delays due to accidents and breakdowns. When a traffic accident or delay occurs, the user cannot move according to the scheduled time according to the route guided by the route search server or the like. Various methods for providing traffic information related to transportation to users have been studied.

  For example, in the following Patent Document 2 (Japanese Patent Laid-Open No. 2002-342425), for a halfway station included in the route from the current position to the destination, a margin time at each station is calculated and presented to the user. An invention of a route presentation service system is disclosed.

  In this route presentation service system, the start point-end point search / result storage unit searches the arrival and departure times at each station according to the timetable in the forward direction from the current position of the user's mobile terminal to the destination, and starts from the destination. Search for departure / arrival times that must arrive at each station according to the timetable in the reverse direction to the station, and the main control unit obtains the arrival / departure times at each station obtained by the forward search of the start point-end point search / result storage unit. In addition, according to the end point-start point search / reverse direction search of the storage unit, the surplus time at each station is calculated, and the user's mobile phone terminal surplus time is notified. It is.

  Further, in Patent Document 3 (Japanese Patent Laid-Open No. 2001-325393) described below, information on a place where the user should be located at the current time point and a train accident is acquired on the route from the current position to the destination. And an invention of a travel time management method for grasping a detour route in real time.

  According to the travel time management method of the present invention, a route search unit searches for a train route to reach the destination according to a destination and a target arrival time input in advance by the user, and the user who is moving Based on the route, the mobile communication means to be carried, such as a point where the user should be present to arrive at the destination according to the target arrival time, and a train accident occurring on the route, etc. According to the information, at least one of the detour routes searched by the route search means in order to avoid train delay due to the train accident or the like is transmitted in real time.

JP 2001-165681 A (FIGS. 1 and 2) JP 2002-342425 A (FIGS. 5 and 7) JP 2001-325393 A (FIGS. 2 and 3)

  According to the technique of the above-mentioned Patent Document 2, it is possible to know how much time is left at a transfer station or the like on the route of the route being guided, but when the train is delayed, the notified time is shifted. In that case, if the technique of the above-mentioned Patent Document 3 is applied, a detour route for avoiding the delay can be obtained when the train is delayed. However, even when a train delay is detected, there are various causes for the delay. Failures and accidents may cause delays in operation and significant delays, and there may be minor delays due to disruption of operation schedules due to weather, congestion, and transfer due to delays in operation on other routes.

  In the latter case, even if a train delay is detected, the delay time is small, so that the delay is within the allowable range for the user, and in many cases it is substantially equivalent to no delay. Such a phenomenon is a place that many people experience well on a daily basis. In such a case, according to the technique of Patent Document 3, the delay information is acquired using the communication means, the search for the detour path, and the reception of the detour path. There was a problem that the processing load of the server was increased unnecessarily.

  Furthermore, according to the technique of Patent Document 3, the user can grasp a detour route in consideration of current information such as a train accident in real time when the user is behind the planned movement. However, this technology requires that the user always acquire the current position and transmit the current position to the server. With a device with a limited charging capacity, such as a mobile phone, the travel time from the departure point to the destination is very long. If it is long, there is a problem that it is difficult to realize. In addition, for example, when a signal for acquiring the current position cannot be appropriately acquired in a tunnel or underground, and the current position cannot be transmitted to the server, information according to the user's current position cannot be distributed to the user. The problem arises.

  As a result of various studies to solve the above problems, the inventor of the present application has made a request for a route search from the terminal device to the route information guidance server to the route information guidance server or a route search request to the route information guidance server.

Enter one of the following. Any of the above sort conditions may be selected from a pull-down menu. When the candidate route sorting condition is not set, a search request for the optimum route (the route with the shortest required time) is made. In FIG. 3, the order in which the number of times of transfer is small is set as the sorting condition.

  When the terminal device 20 wants to receive a traffic information distribution service according to the present invention from the route information guidance server 30 for a desired route including a route section using a transportation facility, the information on the route information is included. Information on the delivery destination, for example, the e-mail address of the terminal device 20 is registered in the route information guidance server 30.

  FIG. 4 is a diagram illustrating an example of accumulated route data registered in the registered route database 37 of the route information guidance server 30 from the terminal device 20. The route information to be registered may be the route information acquired by the terminal device 20 in the past, or the route data searched by the route information guidance server 30 based on the route search request can be registered as it is. The example of the registered route shown in FIG. 4 shows an example in which the terminal device 20 transmits a route search request to the route information guidance server 30 and registers the route search result in the route guidance information server 30 as a registered route. In the following, details of the process will be described by taking as an example a process of registering the route information searched in the route information guidance server 30 when the terminal device 20 requests the route information guidance server 30 for a route search.

  First, the terminal device 20 uses a route information guide server via the communication unit 21 using the departure point, destination, and time information (departure time information, desired arrival time, etc.) received from the menu screen by the operation input unit 26 as route search conditions. 30. At this time, the terminal identification information is also transmitted to the route information guidance server 30 together with the route search condition. As the terminal identification information, for example, when the user uses a mobile phone as the terminal device 20, the mobile terminal ID may be transmitted as the identification information.

  The route information guidance server 30 stores information on a delivery destination such as traffic information (for example, an e-mail address) in the registered route database 37 in advance in association with terminal identification information by user registration. The information on the delivery destination may be designated when the route search condition is transmitted. The terminal identification information and distribution destination information are stored in the registered route database 37. The registration route database 37 may be a user registration information storage unit that stores user information.

  In the route information guidance server 30, the route search means 39 performs a route search according to the route search condition and calculates one or a predetermined number of optimum routes (candidate routes). Here, for example, as a result of the route search from the departure point S to the destination G, it is assumed that three candidate routes have been searched.

  The route 1 is a route from the departure point S to the station A by the railroad a, and after getting off at the station A, going to the destination G on foot. The route 2 is a route from the departure point S to the station B by the railroad b, and further to the railroad d to the station C, and after getting off at the station C, going to the destination G on foot. The route 3 is a route which gets on the railroad b, gets off at the D station, then walks to the F bus stop, and goes from the F bus stop to the destination G. The route information is stored in the registered route database 37 in association with the identification information of the terminal device 20 (see FIG. 4).

  Next, the delivery time zone calculation means 371 sets (calculates) a delivery time zone for delivering traffic information, as will be described later, based on this time information. The distribution time zone (delivery target time) defines a time zone in which operation information is acquired for the transportation facilities acquired through routes 1 to 3. The traffic information acquisition means 372 sends information on the route (registered route) to be distributed regarding the operation information of the route transportation facility from the information distribution server 50 (see FIG. 1) to the used transportation facility (route using the transportation facility included in the registered route). (Section) operation information and time information are acquired. At this time, the target route to be distributed regarding the operation information of the transportation facility may be one route registered by the terminal device 20, or may be a plurality of candidate routes as shown in FIG.

  About the case where the object at the time of distributing the operation information of transportation facilities with respect to a plurality of routes is routes 1 to 3 shown in FIG. 4 and routes 1 to 3 are accompanied by time information as shown in FIG. The subsequent processing will be described. When the candidate routes 1 to 3 are obtained, the traffic information acquisition unit 372 first acquires the use transportation information from the route data (route 1 to route 3 data). For example, in this case, the transportation operation information to be acquired relates to the railway a, railway b, railway c, and bus d.

The time information of each route is as follows.
<Route 1>
Departure point S (16:03) → (Railway a) → Station A (16:22) → (Walk) → Destination G
<Route 2>
Departure point S (16:05) → (Railway b) → B Station (16:12) → (Railway c) → C Station (16:18) → (Walk) → Destination G
<Route 3>
Departure point S (16:05) → (railroad b) → D station (16:10) → (walk) → F station (16:14) → (bus d) → destination G

  The delivery time zone calculation means 371 sets (calculates) a delivery time zone based on this time information. The distribution time zone (delivery target time) defines a time zone in which operation information is acquired for the transportation facilities acquired through routes 1 to 3. For example, the distribution target time for the railway a is the time zone calculated in consideration of play time (such as extra time) since the scheduled boarding time of the user of the railway a is from 16:03 to 16:22. Is the delivery time zone. Here, the play time is defined as one hour, and the time zone including the play time is defined as the distribution time zone. In this case, the distribution time zone regarding the railway a is from 16:03 to 17:22.

  Further, the distribution time zone may be from the search start time of the routes 1 to 3 to the time considering the play time. By doing so, it becomes possible to know in advance even if there is a delay or a cancellation in the transportation operation information between the searched time and the actual boarding time. As described above, the calculation of the distribution time zone may be changed according to the needs of the user of the terminal device 20, or the user may be able to select from several options.

  Similarly, the railway b is a transportation facility used on the route 2 and the route 3. In this case, the distribution target time is determined with respect to the maximum use time band obtained by adding the scheduled boarding times of the two routes. As described above, when the route sections using the transportation system are the same type, for example, the route sections using the transportation system of the same route, the route sections are respectively different route sections and different boarding times. Even if it is a route section of the same route, the distribution time zone is calculated so as to cover all of the time zone, and the terminal device 20 can acquire the traffic information on the route during that time. Become.

  When the distribution time zone of each route is calculated in this way, the route information guidance server 30 edits the route guidance data of routes 1 to 3 and transmits the data to the terminal device 30, and also transmits the transmitted route data to the terminal device. The identification information of 20 is associated (associated) and stored in the registered route database 37. At this time, the registered route database 37 may store a route search condition when searching for the target route together with the target route to be distributed.

  Subsequently, the route information guide server 30 compares the current time with the distribution time zone (distribution target time). If the current time is after the distribution time zone, the route information is deleted from the registered route database 37, and the process ends. When the current time is before the delivery time zone, the route information guide server 30 compares the current time with the delivery time zone (delivery target time) at predetermined time intervals.

  When the current time is within the time corresponding to the distribution time zone, the traffic information acquisition means 372 determines the operation information based on the transportation corresponding to the routes 1 to 3 registered in the registered route database 37. The information is acquired from the operation information database of the information distribution server 50 (see FIG. 1). Next, with respect to the transportation operation information acquired by the traffic information acquisition means 371, the distribution information determination means 373 determines whether or not the operation information indicating the delay of the transportation means, such as occurrence of delay, accident, cancellation or trouble, is included. To do. When the operation information indicating these delays is not included, the route information guide server 30 compares the current time and the distribution time zone at predetermined time intervals without distributing the traffic information.

  When the traffic information acquired by the traffic information acquisition means 372 includes operation information indicating the delay of the traffic means such as delay occurrence, accident, cancellation, trouble, etc., the route information guidance server 30 includes the terminal identification information. A distribution destination address such as a registered mail address is acquired from the registered route database 37, and the operation information of the relevant transportation facility is transmitted by mail to the distribution destination address.

  FIG. 5 is a diagram illustrating an example of a display screen of traffic information distributed from the route information guide server 30 to the terminal device 20. As shown in FIG. 5, in the traffic information delivery mail 40 including the transportation operation status, the information on the route having a delay or cancellation, and the traffic information delivered to the terminal device 20 are naturally the terminal device. 20 is a route section using the transportation included in the route registered in the route information guidance server 30, that is, traffic information related to the route of the transportation related to the registered route, and the route is delayed in the distribution time zone. It is traffic information when the operation information shown is included. In the example of FIG. 5, traffic information is displayed indicating that the “10:00 am line has been postponed due to personal injury”.

  Moreover, URL 41 which can access the site which can confirm the detail of operation information is displayed on this display. The user can acquire more detailed traffic information by linking to the displayed URL 41. Further, a URL 42 for re-searching the route according to the operation status may be displayed. In this way, when the user knows that there is a delay in the registered route, the user can link to this URL and cause the route information guidance server 30 to search again for a detour route to the destination.

  Therefore, the URL 42 includes an instruction for performing processing for the terminal device 20 to acquire the current position when the user links to the URL 42 and to transmit the current position information to the route information guide server 30 together with the terminal identification information. When the route information guidance server 30 receives the current position and the terminal identification information from the terminal device 20, the route information guidance server 30 acquires the destination from the candidate route or the route search condition registered in the route information guidance server 30 in association with the terminal identification information. The optimum route or candidate route at the current time is re-searched from the current position to the destination.

  According to such processing, the terminal device 20 is searched in accordance with the route search condition transmitted to the route information guidance server 30 or the data of the desired route in association with the terminal identification information first transmitted to the route information guidance server 30. By storing the route data in the registered route database 37, the terminal device 20 receives the necessary traffic information from the route information guidance server 30 by mail delivery even if the route guidance is not always displayed. Since it can be confirmed, it is possible to reduce power consumption for displaying route guidance.

  Further, there is no need for the terminal device 20 to always detect the position by the position detection means 22 and transmit the position information to the route information guidance server 30, so that the terminal device 20 can acquire information and transmit information such as position information. It becomes possible to reduce power consumption.

  Furthermore, even if the terminal device 20 does not transmit location information to the route information guidance server 30, it selects which route by calculating the distribution time zone of all routes for the optimum route and a plurality of candidate routes. Even if the user moves, appropriate traffic information can be distributed.

  Next, the concept of route search in the route information guidance server 30 will be described. As the network data for route search, road network data 35 for searching for a travel route by foot or car and traffic network data 36 for searching for a travel route using public transportation are stored. The route searching means 39 searches for a route by walking or a car or a route using both walking and transportation by referring to the network data for route search.

  The road network data 35 is configured as follows. For example, when the road is composed of roads A, B, and C as shown in FIG. 6, the end points, intersections, and inflection points of the roads A, B, and C are used as nodes, and the roads connecting the nodes are directed. Link cost data expressed as links, with node data (node latitude / longitude), link data (link number) and link cost of each link (link distance or time required to travel the link) as data Consists of.

  That is, in FIG. 6, Nn (◯ mark) and Nm (◎ mark) indicate nodes, and Nm (◎ mark) indicates a road intersection. Directional links connecting the nodes are indicated by arrow lines (solid line, dotted line, two-dot chain line). As for the links, there are links facing in the upward and downward directions of the road, but in FIG. 6, only the links in the direction of the arrows are shown for the sake of simplicity.

  When route search is performed using such road network data as a route search database, links linked from the starting node to the destination node are traced to accumulate the link cost, thereby minimizing the accumulated link cost. Search and guide the route. That is, in FIG. 6, when a route search is performed with the departure point as the node AX and the destination as the node CY, the road travels from the node AX to the road A, turns right at the second intersection, enters the road C, and reaches the node CY. The link cost is accumulated sequentially, and a route that minimizes the accumulated link cost is searched for and guided.

  Although other routes from the node AX to the node CY are not shown in FIG. 6, there are actually other such routes, so that a plurality of routes that can be reached from the node AX to the node CY are displayed. A search is performed in the same manner, and a route with the lowest link cost is determined as the optimum route. This method is performed by, for example, a known method called the Dijkstra method.

  On the other hand, the traffic network data 36 for route search of the transportation system is configured as follows. For example, as shown in FIG. 7, in the case of traffic routes A, B, and C, each station (each airport on an aircraft route) provided on each traffic route A, B, and C is used as a node, and the nodes are connected. A section is represented by a directional link, and node data (latitude / longitude) and link data (link number) are network data. In FIG. 7, Nn (◯ mark) and Nm (◎ mark) indicate nodes, Nm (◎ mark) indicates a transit point (such as a transfer station) on a traffic route, and a directional link connecting each node. It is indicated by an arrow line (solid line, dotted line, two-dot chain line). As links, there are links facing in the upward and downward directions of the traffic route. In FIG. 7, only the links in the direction of the arrows are shown for the sake of simplicity.

However, the traffic network basically has a different link cost compared to the road network. In other words, in the road network, the link cost is fixed and static. However, in the traffic network, as shown in FIG. 7, trains and airplanes (hereinafter referred to as individual trains and airplanes) that operate traffic routes are used. A plurality of means of transportation). The time of departure from one node and the time of arrival at the next node are determined for each means of transportation (specified by timetable data and operation data), and individual routes do not necessarily link to adjacent nodes. There is a case. This is the case, for example, with express trains and trains that stop at each station. In such a case, a plurality of different links exist on the same traffic route, and the required time between nodes may differ depending on the transportation means.

  In the transportation network illustrated in FIG. 7, a plurality of transportation means (routes) Aa to Ac... Exist on the same link of the transportation route A, and a plurality of transportation means (routes) Ca to Cc. Will do. Therefore, unlike a simple road network, the transportation network of a transportation facility has a data amount proportional to the total number of transportation means (routes such as individual airplanes and trains).

  In order to search for a route from a certain departure point to a certain destination by using such traffic network data 37, all the transportation means that can be used (ride) when arriving from the departure point to the destination are searched. Therefore, it is necessary to identify the means of transportation that meets the search conditions.

  For example, in FIG. 7, when performing a route search with the departure point as a node AX of the traffic route A and specifying a certain departure time and using the node CY of the traffic route C as the destination, the route operates on the traffic route A. Of the transportation means Aa to Ac..., All transportation means after the departure time are sequentially selected as the departure route. Based on the arrival time at the transit node on the transit route C, among all the transit means Ca to Cc... Operating on the transit route C, all combinations of transit means after the time that can be boarded at the transit node. The total time required for each route, the number of transfers, and the like are guided.

  Using such network data, the route search server 30 searches for a plurality of candidate routes from the departure point to the destination according to the route search conditions, and transmits the results to the terminal device 20 as guide route data. If the departure time of the departure place is specified in the route search conditions, the arrival time at the destination is reached. If the arrival time at the destination is specified, the arrival time is reached at the specified time. Therefore, the terminal device 20 can display these together with the details of the route on the display means 25. When the transfer route is included in the guide route, the train to be transferred at the transfer station and its departure time can be displayed in the same manner.

  In route search when walking and transportation are used as means of movement, road network data 35 and traffic network data 36 are combined to edit comprehensive network data and perform route search. The road network data 35 is referred to for the walking route section, and the traffic network data 36 is referred to for the route section using the transportation facility. In the search for the optimum route, the route having the minimum route cost in total is searched. In this case, a route that does not minimize the walking route section may be searched.

  FIG. 8 is a flowchart showing an operation procedure of the route information guidance server 30 that distributes traffic information. Here, it is assumed that the identification information of the terminal device 20 and the information on the distribution destination of the information distributed to the terminal device 20 have been registered in the route information guidance server 30 in advance. As shown in FIG. 8, the route information guidance server 30 receives route search conditions from the terminal device 20 in step S101. In the process of step S102, the route search means 39 searches for the optimum route or a predetermined number of candidate routes including the optimum route based on the route search condition received in the process of step S101.

  Subsequently, the process proceeds to step S103, and the distribution time zone calculation means 371 acquires the transportation means of the candidate route calculated in step S102 (such as the route section of the route section using the transportation means), and in step S104, in step S103. Calculate the distribution time zone of the acquired transportation information. As described above, the distribution time zone calculation method is obtained by adding a margin time to the boarding time of the route section using the transportation. In step S105, the route information guide server 30 transmits the candidate route data as guide route information to the terminal device 20, and sends the route data to the terminal device 20 identification information, distribution destination information, and distribution time zone. Are registered in the registration route database 37 together with the above information.

  Next, the process proceeds to step S106, where the route guidance information distribution server 30 acquires the current time, and determines whether or not it is within the range of the distribution time zone of the route registered in step S107. If the current time is before the range of the distribution time zone, the step returns to the current time acquisition process of S106.

  If the current time is within the range of the distribution time zone, the process proceeds to the process of step S108, and the traffic information acquisition unit 372 acquires operation information of the related transportation facility. Next, in the process of step S109, the distribution information determination unit 373 determines whether the traffic information acquired by the traffic information acquisition unit 372 in the process of step S108 includes information indicating a delay. When the information indicating the delay is not included, it is not necessary to distribute the traffic information to the terminal device 20, and the process returns to the current time acquisition process in step S106.

  If it is determined in the determination process of step S109 that the traffic information includes information indicating a delay, the process proceeds to the process of step S110, and the operation information distribution means 33 refers to the registered route database 37 to obtain the data of the corresponding route. Distribution destination information such as a distribution destination mail address stored according to the registered identification information of the terminal device 20 is acquired, and the traffic information of the transportation facility acquired in step S108 is distributed in the process of step S111. Return to the current time acquisition process. As a result, when trouble (information indicating delay) is included in the transportation operation information when the current time is within the distribution target time range, the delay related to the registered route is sequentially added to the corresponding terminal device 20. It becomes possible to distribute the traffic operation information including the operation information.

  If it is determined in the time determination process in step S107 that the current time is later than the distribution time range, the process proceeds to step S112, and the registered route data is deleted from the registered route database 37. Thus, the process ends.

  In addition, although the process which receives the route search condition newly set in the terminal device 20 was demonstrated in step S101, the history of the optimal route and candidate route which the terminal device 20 obtained by the route search in the route information guidance server 30 in the past. When the information is stored in the route information guidance server 30, it is possible to obtain a destination in the stored route data and set it as a processing procedure as a destination of the route search condition in the new route search. is there.

  Next, an operation procedure of the terminal device 20 that has received the traffic information from the route information guidance server 30 will be described. FIG. 9 is a flowchart illustrating an operation procedure of the terminal device 20 when a delivery is received from the route information guidance server 30 regarding the operation information of the transportation facility. In step S201, when the terminal device 20 receives distribution of transportation operation information (traffic information) from the route information guidance server 30, the process proceeds to step S202, and the received transportation operation information is displayed. For example, in the case of delivery by e-mail, display processing is performed upon receiving a user's display instruction based on a mail reception notification.

  Next, in step S203, selection of URL 42 (see FIG. 5) for re-searching the route according to the operation status from the user, that is, re-search processing of the route (detour route) to the route information guidance server 30 together with the terminal identification information. It is determined whether or not there is an acceptance of an instruction to transmit.

  If there is no reception of a command for performing processing to be transmitted to the route information guidance server together with the terminal identification information, the processing proceeds to step S208. When there is an acceptance of a command for performing a process of transmitting to the route information guidance server together with the terminal identification information again, the process proceeds to step S204, and the current position detecting unit 22 acquires the current position of the terminal device 20.

  Subsequently, in step S205, the terminal identification information is transmitted to the route information guidance server 30 together with the current position information of the terminal device 20 acquired in step S204. In step S206, when the route guidance information that is the re-search result is received from the route information guidance server 30, the terminal device 20 displays the route guidance information (route data) in S207. In step S208, upon receiving a display end instruction, the terminal device 20 ends the process.

  As described above in detail, according to the present invention, the terminal device 20 that has registered the route does not need to perform an operation of acquiring traffic information related to an accident or delay during the movement of the registered route. 30 only needs to acquire the traffic information only in the distribution time zone calculated by the registered route, and distribute the operation information to the terminal device 20 only when necessary information is included. Even if the terminal device 20 does not transmit the position information to the route information guidance server 30, the distribution time zone of all the registered routes is calculated for the optimum route and a plurality of candidate routes. Appropriate traffic information can be distributed regardless of the route selected.

  According to the present invention, even if the terminal device does not always display guidance, it can receive and confirm necessary traffic information by mail delivery, which contributes to reduction of power consumption for guidance display. Can do. Further, it is not necessary to constantly transmit the position information of the terminal device to the route information guidance server, and it is possible to contribute to the reduction of power consumption for performing position acquisition and information transmission such as position information in the terminal device.
