Next, operation | movement of the destination display system 1 of this Embodiment is demonstrated.
FIG. 7 is a flowchart for explaining the flow of the destination display process performed in the destination display system 1. In FIG. 7, operations of the mobile terminal 2 and the server 3 will be described.
When the destination display process of FIG. 7 is started, the server 3 provides an operation input screen related to map distribution in response to a request from the mobile terminal 2 and is displayed on the display unit 204 of the mobile terminal 2. It is assumed that information or a request input on the operation input screen is received and processing according to the request is executed.

The mobile terminal 2 receives a destination input from the user on the above-described operation input screen. The mobile terminal 2 transmits the input destination to the server 3 (step T101). The destination may be input as information such as a facility and an address, or may be input as latitude and longitude information. The server 3 obtains the latitude and longitude of the destination received from the mobile terminal 2 and stores it in the RAM (step S101).
In addition, the mobile terminal 2 acquires the current position by the position information acquisition unit 208 and transmits it to the server 3 (step T102). The server 3 receives the current position information acquired from the mobile terminal 2 and stores it in the RAM (step S102).
In step T102 and step S102, the server 3 may request the mobile terminal 2 that has selected the destination to acquire the current position in order to reliably acquire the current position.

  The server 3 calculates a map range and a reduction ratio so that both the acquired destination and current position are displayed on the display unit 204 of the mobile terminal 2 (step S103). Obtained from the database 308 and distributed to the mobile terminal 2 (step S104). The mobile terminal 2 acquires map data from the server 3 and displays it on the display unit 204 (step T103).

  Next, the server 3 refers to the movement history information 82 in the database 308 and is the movement history information 82 of the target mobile terminal 2, and the position information 82 c is currently presented to the mobile terminal 2. Those within the map range are acquired (step S105). Then, a road that has been traveled in the past (hereinafter referred to as a past traffic road) is obtained from the position information 82c and the date / time information 82b of the acquired movement history information 82 (step S106). And the information which designates the calculated | required past traffic road is transmitted to the mobile terminal 2 (step S107). The mobile terminal 2 highlights the past traffic road on the presented map in accordance with the information transmitted from the server 3 (step T105).

  The past traffic road is obtained, for example, by arranging the position information 82c of the close date and time in the movement history information 82 acquired in step S105. For example, when the user is at point A at time t1 and at point B at the next time t2, the road connecting point A and point B becomes the past traffic road. If there is a straight line connecting the point A and the point B, the road becomes a past road. Also, for example, when the user turns around the intersection from point A to point B, the road around point A, the road around point B, and the vicinity of both point A and point B What is necessary is just to obtain the past traffic road from the information of the existing intersection. When obtaining a past traffic road, it is desirable to obtain a moving direction from the date / time information 82b.

  When the server 3 calculates and displays all past roads using the movement history information 82 within the map range being presented, the server 3 transmits an instruction to display the current position and destination on the map to the mobile terminal 2. (Step S108). The mobile terminal 2 displays the current position and the destination on the map according to the instruction transmitted from the server 3 (step T105), and ends the destination display process.

FIG. 8 is a display example of the map 71 displayed on the mobile terminal 2 in the destination display process.
In the above-described destination display processing, when four past roads 72, 73, 74, 75 are calculated within a range including the destination 65 and the current position 66, the mobile terminal 2 uses the map 71 of the range. The past past roads 72, 73, 74, and 75 are highlighted.
As an example of highlighting, as shown in FIG. 8, the road may be surrounded by a line, or may be displayed conspicuously in a color different from the surroundings. Further, the surrounding map 71 may be displayed lightly and transparently (indicated by a broken line in FIG. 8), and only the past roads 72, 73, 74, and 75 may be displayed darkly. Similarly, when the destination 65 and the current position 66 are displayed on the map, the destination and the current position are surrounded by a line, displayed in a different color from the surroundings, or transmitted through the surrounding map 71. The destination and the current position may be displayed darkly.

  As described above, in the destination display system 1 of the present embodiment, when the destination is displayed on the map 71, the past traffic road around the destination is calculated from the movement history of the user (mobile terminal 2). , Highlight on the map. Therefore, the user can grasp the state around the destination as information of a region having an area called a road only by looking at the map 71, and the map can be read easily. In addition, since the route taken up to the point of displaying the map is also displayed as a past traffic road, the direction indicated by the map and the direction at the actual location can be grasped instantaneously, which is effective for reading the map. Since past roads are displayed with emphasis, the user can easily grasp and memorize the positional relationship between the surrounding roads and the destination.

[Second Embodiment]
In the first embodiment described above, the server 3 calculates past traffic roads around the destination selected by the mobile terminal 2 and highlights them on the map displayed on the mobile terminal 2. However, it is also possible to calculate a route from the current position to the destination and display the navigation.
9 to 11 are flowcharts for explaining the flow of the route display process, and FIG. 12 is a screen display example in the route display process of the second embodiment.
In the flowcharts of FIGS. 9 to 11, the operation of the server 3 is mainly described, and the description regarding the operation of the mobile terminal 2 is omitted.
In the route processing according to the second embodiment, route guidance is performed so as to pass the past traffic road as much as possible.

  First, the server 3 executes the destination display process of FIG. 7 while communicating with the mobile terminal 2 (step S201). As shown in FIG. 8, the server 3 presents a map 71 highlighting past roads 72, 73, 74, and 75 around the designated destination to the mobile terminal 2, and displays the display unit 204 of the mobile terminal 2. In this state, the past traffic roads 72, 73, 74, 75, the destination 65, and the current position 66 are displayed on the map 71 presented from the server 3.

  In this state, the server 3 receives a designation input of a position on the map from the mobile terminal 2. When the server 3 receives an input from the mobile terminal 2 (step S202), the server 3 acquires information on past roads around the designated point. That is, the server 3 acquires all the movement history information 82 within a predetermined distance range from the designated point, calculates past roads, and stores them in the RAM as a list H of past roads. If there is no past road information in the list H, it waits for designation of another point (Step S204; No → Step S202).

  When there is one or more past road information in the list H (step S204; Yes), the past roads in the list H are compared with each other, and the similarity of the route is calculated (step S205). For past roads with a similarity equal to or greater than a predetermined threshold, those other than the newest are excluded from the list H (step S206). That is, only the latest past road is left for roads that have been passed many times.

  Thereafter, the server 3 transmits a screen erasure instruction to the mobile terminal 2 (step S207), and instructs the mobile terminal 2 to display a map (step S208). Further, the server 3 acquires one past road from the list H (step S209), and instructs the mobile terminal 2 to display the past road on the map (step S210). Similarly, the mobile terminal 2 is instructed to display all past traffic roads in the list H on a map.

  When an instruction to display all past roads in the list H on the map (step S211; Yes), the server 3 further instructs to display the current position and destination on the map (step S212). The detailed information on the past traffic road is transmitted to the mobile terminal 2 and an instruction to display the list is given (step S213). For example, as shown in FIG. 12, the mobile terminal 2 goes to detailed information (date / time information (○ month × day) and route information including destination information (“Restaurant XX”) when passing through a past traffic road. Popup). These pieces of detailed information are assumed to be stored as additional information of the movement history information 82.

  Next, the server 3 instructs the mobile terminal 2 to select which route through which the route to be calculated among a plurality of past roads displayed is to be calculated. That is, the selection input of the past traffic road from the mobile terminal 2 is received (step S214 in FIG. 10), and when any past traffic road is selected from the mobile terminal 214 (step S215), the selected past traffic is selected. A route from the current position 66 to the destination 65 is calculated so as to pass through the road as much as possible (step S216). The server 3 refers to the map data 81 in the database 308, and acquires landmarks at the branch points of the route to the past traffic road and the destination 65 (step S217). Further, the server 3 calculates the branch direction at the branch point between the past road and the route to the destination 65 (step S218).

  Then, the server 3 transmits a screen erasure instruction to the mobile terminal 2 (step S219 in FIG. 11), and then instructs to display a map (step S220). Further, the server 3 instructs the mobile terminal 2 to highlight the selected past road (step S221), and displays the route to the destination 65 obtained in step S217 on the map. Is performed (step S222). In addition, the server 3 instructs the mobile terminal 2 to obtain detailed information on the selected past traffic road from the movement history information 82 (additional information 82d, 82i) of the database 308 and display it (Step S3). S223). Thereafter, the server 3 instructs the mobile terminal 2 to display the current position 66 and the destination 65 (step S224).

  The server 3 determines whether or not the movement direction of the past traffic road is the same direction as the movement direction of the route calculated this time (step S225), and if it is the same direction as before (step S225; Yes), The route is traced in the same direction as before, and information indicating that the vehicle branches in the branch direction at the landmark of the branch point is transmitted to the mobile terminal 2 (step S226). If the direction is the reverse of the previous direction (step S225; No), the route is traced in the reverse direction to the previous direction, and information indicating that the branch point is branched in the branch direction is transmitted to the mobile terminal 2. (Step S227).

  In the mobile terminal 2, according to the information received from the server 3, the route is traced in the same direction as before (or in the opposite direction), and the fact that the branch point is branched in the branch direction is output by display or voice. Inform the user.

  Further, the server 3 confirms whether or not the past road has changed since the previous time with reference to the past map data 83 (step S228). When the past traffic road has changed compared to when it passed previously (step S228; Yes), information indicating that the map has changed is transmitted to the mobile terminal 2 (step S229). If the past road has not changed compared to when it passed previously (step S228; No), the process is terminated.

Detailed information is presented when the road is displayed.

  Further, the server 3 determines whether or not the route of the previous past road and the current route are in the same direction, and the route to the branch point (= the point away from the route of the previous past road) is in the same direction. Information such as whether or not the mobile terminal 2 is in the reverse direction is presented to the mobile terminal 2. Even if it is a road that the user has traveled before, the scenery is different if the traveling direction is reverse to the previous direction, so it is useful to present the same direction or the reverse direction. Further, the server 3 presents the landmark of the branch point and the branch direction (such as right or left) at the branch point to the mobile terminal 2. Since the route after the branch point is a road that the user passes for the first time, it is useful to present information related to the branch point (landmark and branch direction of the branch point).

  Further, the server 3 has the past map data 83, and when there is a change in the past traffic road presented to the mobile terminal 2, the server 3 obtains the change information of the past traffic road, Present.

  In this way, when displaying past traffic roads, the user can easily understand the map based on his / her own experience in order to display additional information on past movements, road change information, and the like together. become. Accordingly, the map can be read more easily.

  In the first and second embodiments described above, the mobile terminal 2 displays information such as maps and past traffic roads distributed from the server 3. A function may be provided. That is, the control unit 201 of the mobile terminal 2 acquires the current position information by the position information acquisition unit 208 and stores it in the storage unit 202 as a movement history. The control unit 201 receives an input of a destination from the input unit 203. When the destination is input, the control unit 201 refers to the movement history information 82 stored in the storage unit 202 and inputs the input destination. A past traffic road that has passed through the surrounding roads is calculated, a map including the destination is displayed on the display unit 204, and the past traffic road is clearly indicated.

  Further, the control unit 201 of the mobile terminal 2 accepts selection of the displayed past traffic road, and the control unit 201 calculates and presents a route that reaches the destination through the selected past traffic road as much as possible. It may be.

  In addition, the control unit 201 of the mobile terminal 2 stores detailed information related to the route such as the past destination (destination), the movement date and time, the route, the photograph, and the facility information in association with the movement history information 82. Further, when displaying the past traffic road, the detailed information thereof may be presented.

  In addition, the control unit 201 of the mobile terminal 2 has the past map data 83, and when there is a change in the past traffic road being presented, the change information of the past traffic road is obtained and presented. Also good.

  In addition, the control unit 201 of the mobile terminal 2 determines whether or not the previous past road route and the current route are in the same direction, and reaches a branch point (= a point away from the previous past road route). Information such as whether the route is in the same direction or in the opposite direction may be presented. Furthermore, the control unit 201 of the mobile terminal 2 may present a landmark at the branch point and a branch direction (such as right or left) at the branch point.

  Thus, if map data and movement history information are memorize | stored by the mobile terminal 2 side, the destination display of this invention is realizable only by the mobile terminal 2 without performing communication with the server 3. FIG.

  In addition, this invention is not limited to what is described in the above-mentioned embodiment. It will be apparent to those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea disclosed in the present application, and these are naturally within the technical scope of the present invention.
