  Next, the operation of the train route guidance system according to the embodiment of the present invention will be described with reference to FIGS. FIG. 6 is a flowchart showing the operation of the train route guidance system according to the embodiment of the present invention, and FIGS. 7 to 10 are views showing examples of display on the mobile phone with a GPS receiver of the user.

  First, when the user 1 accesses the guidance center 2 using a browser of the mobile phone 11 with a GPS receiver and executes a route search application or the like, for example, a search screen as shown in FIG. The person 1 inputs the visited telephone number (S101). In S101, the user 1 can directly input the telephone number to be visited, or select a visiting party from the telephone book already installed on the mobile phone 11 with GPS receiver from the “select from telephone book list” button. You can also enter a phone number to visit.

  If the arrival date or arrival time is specified, the arrival date or arrival time is input (S102). In S102, the user 1 can directly input the arrival date, or can directly select the arrival date from the calendar display screen as shown in FIG. 8 after pressing the “select arrival date from calendar” button.

  When the user 1 presses the “Search” button shown in FIG. 7 after completing the input in S101 and S102, the input content is transmitted to the guidance system server 5 of the guidance center 2. At this time, the current position information is also transmitted from the user's GPS receiver-equipped mobile phone 11 to the position information processing unit 15 of the positioning server 4.

  The information transmitted from the mobile phone 11 with the GPS receiver of the user 1 is received by the transmission / reception unit 14 of the guidance system server 5 and the position information processing unit 15 of the positioning server 4, and the position information processing unit 15 uses the information. The position of the user 1 is detected based on the information transmitted from the mobile phone 11 with the GPS receiver of the user 1 (S103). The detected position information is corrected when necessary, and is sent to the map information processing unit 20 as longitude / latitude information represented by a two-dimensional vector (X1, Y1). In addition, the transmitting / receiving unit 14 sends the visited telephone number transmitted from the mobile phone 11 with the GPS receiver of the user 1 to the position information processing unit 15.

  Then, the position information processing unit 15 determines whether or not the visited telephone number transmitted from the transmission / reception unit 14 is the telephone number of the mobile phone 12 with GPS receiver (S104). The determination of the visited telephone number in S104 is made based on the first 3 bytes of the visited telephone number, for example. If the first 3 bytes cannot be determined, the number after the first 3 bytes or the visited telephone number Judgment as a whole.

  If it is determined in S104 that the phone number is the mobile phone 12 with GPS receiver, the location information processing unit 15 makes a request for sending the current location information to the mobile phone 12 with GPS receiver at the destination 3. The mobile phone 12 with the GPS receiver of the visited site 3 that has received the request acquires the current position information from the radio wave received from the GPS satellite 21 and sends it back to the position information processing unit 15. Then, the position information processing unit 15 detects the position of the mobile phone 12 with a GPS receiver at the visited location 3 based on the location information transmitted from the mobile phone 12 with a GPS receiver at the visited location 3 (S105). The detected position information is corrected when necessary, and is sent to the map information processing unit 20 as longitude / latitude information represented by a two-dimensional vector (X2, Y2).

  If it is determined in S104 that it is not the telephone number of the mobile phone 12 with GPS receiver, the position information processing unit 15 determines that it is the telephone number of the fixed telephone 13 and uses the information on the visited telephone number as it is. Send to 20. In the map information processing unit 20, based on the visited telephone number sent from the position information processing unit 15, the address of the telephone number is retrieved from the telephone book table 200, and the telephone number of the visited destination 3 is retrieved from the map information table 201. The position is converted into the format (X2, Y2), and the position of the visited place 3 is detected (S106). The detected position information is sent to the map information processing unit 20 as longitude / latitude information.

  Then, the map information processing unit 20 uses the map information table 201 based on the position information of the user 1 and the visited place 3 sent from the position information processing unit 15, and the train / subway station that is within walking distance for each. The nearest station candidate is searched (S107). Information on the nearest station candidate of the user 1 and the nearest station candidate of the visited place 3 that have been searched is sent to the route search processing unit 16.

  The search for the train / subway station within walking distance in S107 is, for example, within walking distance from the longitude / latitude information of the station in the map information table 201 and the current longitude / latitude information (X1, Y1) of the user 1 (X1 The “nearest station candidate of the user” in the coordinate axes of ± α, Y1 ± α) is obtained, and further, the longitude / latitude information of the station in the map information table 201 and the current longitude / latitude information of the destination 3 (X2) , Y2), “the nearest station candidate to visit” within the coordinate axes within the walking distance (X2 ± α, Y2 ± α) is obtained.

  Then, the route search processing unit 16 searches for a route using the train operation status table 170 in the train operation information processing unit 17 for all combinations of “nearest station candidate for visit” and “nearest station candidate for user”. (S108), "the shortest distance / the shortest route", "the nearest station of the user", "the nearest station to be visited" and "the required time" are determined, and the train operation in the train operation information processing unit 17 is performed. The “train operation status” and “congestion degree” of the train are acquired from the situation table 170 and the train congestion degree situation table 171. Further, when there is an estimated arrival time or estimated arrival date input by the user 1 in advance, the “departure time” of the train time to be taken from the “user's nearest station” is also searched using the train operation status table 170. (This processing is not performed when the user has not entered the estimated arrival time and estimated arrival date). In addition, when transfer is necessary, search for transfer guidance information and the like.

  In the route search in S108, a route search is performed for all the combinations of stations of the nearest station candidate of the visited place 3 and the user 1, and for example, the nearest station candidate of the visited place 3 is the station A. When the nearest station candidate of the user 1 is two stations of the station D and the station E at the three stations of the station B and the station C, the search is repeatedly performed until the route search for all six patterns is completed. Then, after all the searches are completed, the time required for using each process is compared, the route information with the shortest travel time or the shortest travel distance, the nearest station of user 1 and the nearest station of destination 3 at that time Further, the congestion status of the train used on the determined shortest route is acquired from the train congestion level status table 171 and the route search including the congestion level information is performed.

  Then, the route search processing unit 16 sends the search result to the transmission / reception unit 14, and the map information processing unit 20 provides the nearest station name of the user and the nearest station name to be visited obtained by the route search processing unit 16. The map information processing unit 20 sends it to the user from the nearest station position (Xa, Ya) and the nearest station position (Xb, Yb) from the location information work table, for example, which is stored as a cache at the time of retrieval. The current location (X1, Y1) of the user and the current location (X2, Y2) of the visited location are extracted and sent to the transmission / reception unit 14.

  In the transmission / reception unit 14, based on information from the route search processing unit 16 and the map information processing unit 20, the current position of the user, the current position of the visited site, the nearest station of the user, the nearest station of the visited site, the shortest distance / the shortest time The data is transmitted to the mobile phone 11 with GPS receiver of the user 1 after performing the display edit processing of the data of the route, the train operation status, the congestion degree and the departure time of the train (S109).

  The data display editing process in S109 includes, for example, the user's nearest station position (Xa, Ya) obtained from the map information processing unit 20, the visited station position (Xb, Yb), and the user's current position. (X1, Y1), the current location (X2, Y2) of the visited location is mapped to the coordinates on the electronic map data in the electronic map database 160, and the station name and transfer guidance information sent from the route search processing unit 16 , And information such as the degree of congestion obtained by the train operation information processing unit 17 is added and edited so that it can be displayed on a Web browser on a mobile phone.

  The mobile phone 11 with the GPS receiver of the user 1 receives the data sent from the guidance center 2 (S110), and the search result is displayed on the Web browser of the mobile phone 11 with the GPS receiver of the user 1. It is displayed (S111).

  The search result displayed in S111 is displayed, for example, as shown in FIG. 9, and the name of the nearest station of the user serving as the departure station (A line a station) and the name of the nearest station of the visiting destination serving as the arrival station ( B line b station), the shortest distance / shortest time route from the user's nearest station to the nearest station to be visited, the time of day, train operation status information on the train route, and the degree of congestion. Furthermore, when the user 1 presses the “position display” button shown in FIG. 9, for example, an electronic map display screen as shown in FIG. 10 is displayed, and the current map information and the current user position, You can know the current location of the destination, the departure station displayed in the search results, and the location of the arrival station.

  Thus, in the present embodiment, the user 1 makes an inquiry to the guidance center 2 using the mobile phone 11 with GPS receiver, and the telephone number of the fixed phone 13 of the other party of the visited site 3 on the mobile phone 11 with GPS receiver. Alternatively, by inputting only the telephone number of the mobile phone 12 with GPS receiver, the route of the shortest distance / the shortest time can be searched from the plurality of nearest station candidates of the user and the plurality of nearest station candidates of the visited site.

  Therefore, even if the name of the station near the current location is unknown, the positioning server 4 of the guidance center 2 automatically obtains the position and searches for the nearest station candidate within the walking distance of the user 1. Even if the trainee does not know the station name of the nearest station, train route search can be performed.

  Even if you do not know the location of the destination 3 or you do not know the nearest station of the destination 3, if the phone number of the destination 3 is known in advance, the positioning in the guidance center 2 is based on the phone number. Since the server 4 acquires the location information of the visited place 3, the user 1 can search for the train route without knowing the nearest station name of the visited place 3.

  Further, even when there are a plurality of nearest station candidates within walking distance of the user 1, all patterns using the stations that the user 1 can use are searched for in the guidance system server 5 in the guidance center 2, The person 1 can search for an optimum train route without repeatedly determining the shortest route by repeatedly performing route searches from a plurality of stations within walking distance.

  Further, even when there are a plurality of nearest station candidates within walking distance of the visited place 3, the user 1 searches for all patterns using the stations available from the destination by the guidance system server 5 in the guidance center 2. However, it is possible to search for the optimum train route without repeatedly determining the shortest route by repeatedly performing route searches from a plurality of stations within walking distance of the visited site 3 by itself.

  Further, in the search screen on the mobile phone 11 with GPS receiver, when a visited telephone number is input, the interface can be selected from the phone book database in conjunction with the phone book function in the mobile phone 11 with GPS receiver. Therefore, the user 1 can search for the train route by simply selecting the name of the visited party or the visited telephone number, and can realize an interface in which the user 1 does not feel bothered to input.

  Furthermore, even if the train or the subway is delayed due to an accident or the like, the route search is performed using the train operation status table 170 reflecting the latest operation status, so the train as the result received by the user 1 as the shortest route Despite the use of, there is no longer a delay in arrival time or getting caught up in train congestion due to diamond disruption.

  In addition, since the user 1 can also know the congestion status of the train in advance, when there are two or more routes searched by the train route search, the route that arrives at the nearest station to be visited earlier due to the congestion status, Even if it takes a little time, you can avoid the crowded train as much as possible and choose the route to reach the nearest station to visit.

  In the present embodiment, the mobile phone 11 or 12 with GPS receiver is used to detect the location of the mobile phone of the user 1 or the visited site 3. As the detection method, for example, another detection method such as a method of detecting a position by the strength of radio waves may be used. The terminal on the user 1 side is not limited to a mobile phone, and an information terminal that can detect the current position may be used.

  Further, in the present embodiment, when the destination telephone number is the fixed telephone 13, the position of the visited destination 3 is detected from the telephone book table 200 and the map information table 201. The location information processing unit 15 makes a request for sending location information to the fixed phone 13 by returning the location information of the fixed phone 13 from the fixed phone 13 and detects the location of the fixed phone 13. You may make it do.

  In the present embodiment, the example in which the search result of the shortest distance / minimum time is displayed as the search result has been described. However, the user 1 is made to input the search priority condition in advance, for example, the search result is input. The search result may be displayed using time, congestion, fare, etc. as priority conditions for the search. In this case, when a plurality of routes are to be searched, the optimal route search result is provided even when the user 1 wants to select a route with a lower congestion level than when the user 1 arrives at the destination 3 earlier. In addition, by displaying a plurality of search results according to the search priority, the user 1 can select an optimum route by comparing the plurality of search results.
