Or a personal computer). In addition, hereinafter, an “isochronous line” refers to a line connecting a plurality of positions that can arrive after a specific time from a specific position, or a plurality of positions that can reach a specific position after a specific time. Say it.

[First Embodiment]
First, a system including a map creating apparatus according to a preferred embodiment of the present invention will be described with reference to FIGS. The present invention is characterized by displaying isochronous lines on a map. In the first embodiment, a train is used as a transportation means, and a user's current position is used as a specific position. .

[Overall configuration of the system including the map creation device]
FIG. 1 is a diagram showing an outline of a system configuration which is a preferred embodiment of the present invention. A map creating apparatus 10 according to the present embodiment is connected to a mobile communication terminal 1 via a communication network 5 including the Internet.

  The mobile communication terminal 1 receives radio waves for position detection from a plurality of GPS satellites 2. In this figure, only one GPS satellite 2 is shown, but as is well known, it is necessary to receive radio waves from at least three, usually four or more GPS satellites 2, in order to specify the position. There is. The radio wave transmitted from the GPS satellite 2 includes various orbit information and very accurate time data by an atomic clock. In order to obtain easy-to-handle position data such as the latitude and longitude of the current position from these information, the mobile communication terminal 1 holds the orbit information of the GPS satellite 2 and the additional information obtained from the nearest base station 3 to perform complicated positioning. It is necessary to perform an operation. Therefore, the position data acquisition server 6 normally connected via the public communication network 4 performs these positioning calculations, and uses the obtained results as position data (latitude, longitude, altitude if possible, etc.). 1 is used. If the mobile communication terminal 1 is equipped with a positioning calculation function, it is also possible to directly acquire position data without communicating with the position data acquisition server 6.

  The mobile communication terminal 1 transmits its own position data such as latitude and longitude obtained in this way to the map creation device 10 of the service provider. The map creation device 10 includes means for generating a screen for providing services and advertisements on a homepage or portal site.

Specifically, the map generating device 10 comprises a position acquisition unit 11, the time obtaining means 12, a transport path DB 13, etc. Time line determination means 1 4及 beauty drawing unit 15.

  Here, the position acquisition unit 11 acquires the current position of the user of the mobile communication terminal 1 based on the position data transmitted from the mobile communication terminal 1. The time acquisition unit 12 acquires the time when the position data is transmitted. Here, the time may be transmitted from the mobile communication terminal 1 or may be independently acquired by the map creation device 10.

  The traffic route DB 13 stores various types of information such as train timetables and routes. The isotime line determination unit 14 refers to information stored in the traffic route DB 13 based on the position data and time acquired by the position acquisition unit 11 and the time acquisition unit 12 and refers to information stored in the traffic route DB 13 (described later). Create 3). The drawing unit 15 creates map data related to a map (see FIG. 4 described later) on which the isochronous line is displayed based on the isochronous line table created by the isochronous line determining unit 14.

[Basic operation of the system including the map creation device]
FIG. 2 is a diagram showing details of a processing flow in the system of the first embodiment.

First, the mobile communication terminal 1 transmits a positioning information request (position data request) to the position data acquisition server 6 periodically or by a user operation. This positioning information request includes GPS satellite information ("Almanac" that is rough orbit information of all GPS satellites 2 and "ephemeris" that is accurate orbit information of the GPS satellite 2 itself). In addition, information on a peripheral reference station (a reference station among the peripheral base stations 3 ) may be included.

The position data acquisition server 6 performs a positioning calculation based on the received information (step S10), and returns a positioning result (data such as longitude, latitude, altitude, reliability, etc. can also be acquired). Alternatively, although not shown, the position data acquisition server 6 performs positioning using information from the nearest base station 3 so that the mobile communication terminal 1 can easily perform the positioning calculation without performing the positioning calculation. “Assist data” for facilitating the transmission may be transmitted to the mobile communication terminal 1, and the positioning calculation may be performed by the mobile communication terminal 1.

  The mobile communication terminal 1 generates terminal position data including the current location and current time of the terminal based on the positioning result thus obtained (step S11), and transmits this terminal position data to the map creation device 10.

  In the map creation device 10, when the terminal position data is received, the current position and the current time are acquired by the position acquisition unit 11 and the time acquisition unit 12 (step S12). In addition, the map creation device 10 acquires necessary information such as a timetable according to the position and time from various information stored in the traffic route DB 13 (step S13), and the time obtained by the isochronous line determination means 14 Based on information such as a table, an isochronous line table (FIG. 3 described later) is created (step S14). If the current position is not one of the stations, it may be more preferable to create an isochronous line table after calculating the time to the nearest station.

  Then, the plotting means 15 of the map creation device 10 plots a map (FIG. 4 to be described later) displaying isochronous lines based on the isochronous line table (step S15), and draws the plotted map data to the mobile communication terminal 1. Send.

[Overview of isochronous line table]
FIG. 3 is a diagram showing an outline of the isochronous line table created by the isochronous line determining means 14. Etc. Time line table, arrival station, the position data comprising a latitude and longitude of route species-specific及 beauty arrival station, are created in association with the train arrival time is later than the current time. Here, the route type defines information about the next station in the arrival station.

For example, when the current time is “15:00”, the isotime line table is created by searching for a station that arrives at the current time “15:00”. to obtain a different route types 及 beauty position data. And, then, "15:01", to search the station to arrive at "15:02"..., The station, is created by acquiring the route species-specific及 beauty position data. In addition, although it is set as the interval of 1 minute about the interval of arrival time, it is not restricted to this, It can change suitably.

[Map showing isochronous lines]
FIG. 4 shows an example of a map on which isochronous lines are displayed. FIG. 4 shows, for example, a map on which an isochronous line is displayed when the current position is A station and the current time is “15:00”.

  On the map in FIG. 4, isochronous lines 151, 153, 155, and 157 are displayed from the current location 100 at intervals of 15 minutes from the current time. The isochronous lines 151, 153, 155, and 157 displayed in this manner can visually grasp a plurality of positions that can be reached from the current location 100 after a specific time has elapsed.

  Note that the interval of isochronous lines can be changed as appropriate. In addition, although the isochronous lines 151, 153, 155, and 157 are displayed by time, they may be displayed by elapsed time. For example, the isochronous line 151 is displayed as “after 15 minutes”, the isochronous line 153 is displayed as “after 30 minutes”, the isochronous line 155 is displayed as “after 45 minutes”, and the isochronous line 157 is displayed as “ “After 1 hour” may be displayed. Also, the number of isochronous lines displayed on the map can be set as appropriate.

[Display of isochronous lines]
Here, a method for displaying isochronous lines in the present invention will be described. The isotime line is displayed by specifying the position of the isotime and creating a line connecting a plurality of specified positions.

  Here, depending on the route of the train (XX line), the interval between isochronous lines and the interval between stations may be different. For example, referring to FIG. 3, when station B arrives at “15:13”, station B2, which is the next station after station B, arrives at “15:16”. Here, the isochronous line needs to be displayed at the position of “15:15”. In the present invention, the station B that can be reached in such a case is assumed to be the position of the equal time. That is, with regard to specifying the position, a station that can be reached at the time indicated by the isochronous line is set as the position. Therefore, the isochronous line 151 is displayed on the B station 101 in FIG.

  Note that the position specification is not limited to this, and a position other than the station may be set as an isochronous position. For example, the position at which the train arrives at the time indicated by the isotime line may be measured by the average train speed × time difference, and the position may be set as the position at the same time. In such a case, the isochronous line 151 is displayed at a predetermined position between the B station 101 and the B2 station 102 station.

  When a plurality of isochronous positions are specified in this way, isochronous lines are created by creating lines connecting the plurality of positions. Note that a line connecting a plurality of positions may be a straight line or a curved line.

[Last train time line]
With reference to FIG. 5, the relationship between the last train and the isochronous line will be described. (1) in FIG. 5 is a map displaying an isochronous line when the current location 100 is A station and the current time is “0:00”, and (2) in FIG. It is a map which displayed the isochronous line when it is A station and the present time is "0:30".

  Referring to FIG. 5, the isochronous line includes a last train time line 161. Therefore, it is possible to visually grasp the range that can be reached by the last train from the current position.

  Here, (1) of FIG. 5 and (2) of FIG. 5 differ in the position where the last train time line 161 is displayed. Specifically, in (1) of FIG. 5 where the current time is “0:00”, the last train time line 161 is displayed over a wide range, whereas the current time is “0:30”. In (2) of FIG. 5, the last train time line 161 is displayed over a narrower range than (1) of FIG. 5.

  Therefore, it can be understood from (1) and (2) in FIG. 5 that the range that can be reached from the current position changes according to the current time. For example, if such a map is transmitted to the mobile communication terminal 1 in real time, it is possible to provide the user with a state in which the reachable range from the current position changes in real time according to the current time.

[Relationship between isochronous intervals and map magnification]
Although spacing of equal time line are as described above for that changes may be made as appropriate, may spacing equal time line more preferable that to have a magnification relevance map. Therefore, with reference to FIG. 6, the relationship between the interval of isochronous lines and the magnification of the map will be described.

  It has been known that the scale can be changed with respect to the display of the map. However, when the map scale is changed from medium to small (wide range is displayed), the interval between iso-time lines may be increased. Desirably, when the magnification of the map is changed from medium to large (a narrow range is displayed), it is desirable to narrow the interval of isochronous lines. Therefore, in the present embodiment, the interval between isochronous lines is also changed in accordance with the change in the map magnification.

  (1) of FIG. 6 is a display example when the magnification of the map is medium, and the intervals of the isochronous lines 151, 153, 155, and 157 are 15 minute intervals. (2) of FIG. 6 is a display example when the map magnification is small, and the intervals of the isochronous lines 171, 173, and 175 are 45 minutes. (3) of FIG. 6 is a display example when the magnification of the map is large, and the interval between the isochronous lines 181, 182, 183, 184 and 185 is 1 minute.

  As described above, in this embodiment, the map magnification and the interval between isochronous lines are related, and when the map magnification is changed, the interval between isochronous lines is automatically changed. As a result, it is possible to display an appropriate isochronous line according to the magnification of the map, and the user can select a plurality of positions that can be reached after a specific time from the current position and current time according to the magnification of the map. It can be grasped visually.

In order to change the interval of equal time line by thus changing the magnification of the map, the map creation device 10, in accordance with the magnification of the map scaling hand Dan及 beauty map for changing a magnification of the map It is desirable to provide isochronous line interval changing means for changing the interval of isochronous lines.

Here, when transmitting the destination and the target time, the mobile communication terminal 1 may acquire the current position and transmit the current position data to the map creation device 10 together with the destination and the target time.

  The map creation device 10 acquires destination data and destination time data (step S22), and acquires necessary information such as a timetable according to the destination and destination time from various information stored in the traffic route DB 13 ( Step S23). Here, in the present embodiment, a plurality of positions that can be reached after the elapse of a specific time “to” the destination “to” are connected by isochronous lines. Therefore, in the process of step S22, it is desirable to obtain a timetable for the train heading to the destination.

  Next, an isochronous line table is created by the isochronous line determining means 14 of the map creating apparatus 10 based on the acquired information such as the timetable (step S24). Also in this processing, it is desirable to create an isochronous line table by searching for a station where a train that can arrive at the destination at the destination arrives and the time.

  Then, the drawing means 15 of the map creating device 10 draws a map (FIG. 9 described later) displaying the isochronous lines based on the isochronous line table (step S25), and draws the drawn map data to the mobile communication terminal 1. Send.
