FIG. 4 shows an example of trip information.
Trip information includes, for example, trip ID, probe ID, time information, latitude information, and longitude information.
The trip information is a lump of probe information that is collected when the vehicle on which the in-vehicle terminal 101 (user terminal 100) is mounted moves from a certain place to a certain place. That is, the trip information indicates a locus (trip) in which the user terminal 100 has moved from a certain place to a certain place. For example, a trip from a starting position such as a parking lot to a stop is treated as one trip. A unique trip ID (Identifier) is assigned to each trip, and each probe information constituting each trip includes a probe ID (Identifier) that can identify the probe information, a time when the probe information was acquired, and the probe information. As the position information of the user terminal 100 when is acquired, the latitude information and the longitude information are included.
When the user terminal (vehicle-mounted terminal) 100 collects probe information for one trip, the user terminal 100 transmits trip information including the probe information to the probe information providing server 200. Upon receiving the trip information, the probe information providing server 200 adds a trip ID to the trip information and stores it in the probe information DB 240.
Depending on the nature of the application, how long it is stopped is regarded as the end of the trip, for example, if it has not moved for 30 minutes.

FIG. 5 shows an example of POI information.

FIG. 6 shows an example of the area entry range designation method in the area entry probe acquisition search method.
The user designates an area in which the inflow amount or inflow direction of the vehicle or the like is to be investigated on the map displayed on the display unit 190 of the user terminal 100. The user terminal 100 displays the designated area so that it can be distinguished from others by overlapping it on the map. In addition, the user designates the date and time in a dialog box displayed on the display unit 190 using the input unit 180 of the user terminal 100. Note that the user terminal 100 may display a text box for designating the date and time on the display unit 190.
Then, the user terminal 100 transmits a search request including the designated area and date / time to the probe information providing server 200. In response to this, the probe information providing server 200 searches the probe information DB 240 and transmits a search result including the probe information to the user terminal 100. The user terminal 100 receives the search result from the probe information providing server 200. The received search result includes trip information such as a vehicle that has flowed into the designated area at the designated date and time. The user terminal 100 displays the trip information (that is, the trajectory of each vehicle, etc.) superimposed on the map displayed on the display unit 190.
Thereby, the user can know the tendency of the inflow amount and the inflow direction of the vehicle or the like to the designated area. When the inflow amount of vehicles or the like to the designated area is large, there may be a popular facility or a popular spot that is not registered in the POI information DB 230 in the area.

  In addition, for example, when the user performs area marketing for opening a new restaurant in a restaurant, the user specifies a planned store opening date and time and requests a search for area entry probe acquisition input unit of the user terminal 100 Input to 180. The probe information providing server 200 returns probe information including a trip whose destination is the area designated by the user (trip information having the designated area as the end of the trip). Based on this, the user terminal 100 displays the trajectory and destination of each trip superimposed on the map displayed on the display unit 190. The user can refer to the results and analyze the amount of cars flowing into the planned opening location and the direction in which the vehicles will flow. The position etc. which should install can be judged.

FIG. 7 shows an example of a next coordinate acquisition designation method in the next coordinate acquisition search method.
The user designates an area that is the starting point of the search in the map displayed on the display unit 190 of the user terminal 100. The user terminal 100 displays the designated area so that it can be distinguished from others by overlapping it on the map. In addition, the user designates the date and time in a dialog box displayed on the display unit 190 using the input unit 180 of the user terminal 100. Note that the user terminal 100 may display a text box for designating the date and time on the display unit 190.
Then, the user terminal 100 transmits a search request including the designated area and date / time to the probe information providing server 200. In response to this, the probe information providing server 200 searches for probe information and POI information and transmits them to the user terminal 100. The user terminal 100 receives a search result including probe information and POI information from the probe information providing server 200. The probe information includes trip information such as vehicles that have flowed out of the designated area at the designated date and time. The POI information is POI information around the end of each trip. The user terminal 100 displays trip information (that is, the trajectory of each vehicle, etc.) and POI information superimposed on the map displayed on the display unit 190. As a result, the user can know what destination (a popular facility or popular spot registered in the POI information DB 230) is moving from the designated area.

For example, the user designates an area around the current location on the map displayed on the display unit 190 when he / she goes out without any particular destination. The probe information providing server 200 searches for trip information about trips flowing out of the area designated by the user, and searches for POI information existing around the end of each trip. The probe information providing server 200 transmits the search result to the user terminal 100. Based on this, the user terminal 100 displays the trajectory of each trip and the POI information superimposed on the map displayed on the display unit 190.
Thereby, the user can know what kind of spot the other user is heading from an area, and can check popular spots and recommended spots. Further, the user terminal 100 can analyze the trip information and propose a route and required time from an area designated by the user to a popular spot or a recommended spot.
In the next coordinate acquisition designation method, it is also possible to omit the designation of the investigation target area and perform a search based on the coordinate information of the current position.

FIG. 8 shows a flowchart of area reception processing for accepting designation of an area by the user in the user terminal 100.
The area reception process is executed by both the area approach probe acquisition search method and the next coordinate acquisition search method.
In the area reception process, for example, when the user touches the touch panel or the like of the input unit 180, the area display unit 155 detects that the designation of the area (position range) has started (S101). The area display unit 155 draws the area according to the designation by the user (S102). When the area entry / next coordinate acquisition unit 151 determines that the area specification is completed and the time range is specified (S103: Yes), the time range information indicating the area coordinate information and the time range on the screen. Is acquired (S104). The area approach / next coordinate acquisition unit 151 converts the coordinate information on the screen into latitude information and longitude information based on the latitude and longitude of the map being displayed. Then, the request transmission unit 153 transmits a search request including area information indicating the position of the area converted into latitude information and longitude information and time range information to the probe information providing server 200 (S105).
On the other hand, the area display unit 155 indicates that the area specification is incomplete (for example, the finger is released before specifying one closed area) or the time range is not specified (S103: No). Then, the area in the middle of drawing is erased, and the area designation is started. In addition, if the area display unit 155 determines that the specification is inappropriate, such as when the user does not specify a time range, such as “Please specify the time.” May be displayed on the screen.

FIG. 9 shows a flowchart of an example of search processing by the area entry probe acquisition search method in the probe information providing server 200.
When the request reception unit 281 receives a search request from the user terminal 100 (S111), the probe search unit 284 searches for trip information from the probe information DB 240 based on the area information and time range information included in the search request. (S112). Specifically, the probe search unit 284 selects the probe end probe information belonging to the designated area and having the time within the designated time range. And if there exists applicable trip information, the probe search part 284 will acquire all the probe information which belongs to the trip information as a search result. The response response unit 283 transmits the acquired probe information as a search result to the user terminal (S113).

FIG. 10 shows a flowchart of an example of processing for displaying a search result by the area approach probe acquisition search method in the user terminal 100.
When the response receiving unit 156 receives the search result from the probe information providing server 200 (S121), the result display unit 154 determines whether or not the trip information is included in the result (S121). If the trip information is not included (S121: No), it means that there is no trip information related to the designated area, so the result display unit 154 shifts to a state of waiting for designation of the area without performing display processing ( S123).
On the other hand, when one or more pieces of trip information are included (S121: Yes), the result display unit 154 displays the latitude information and longitude information included in the individual probe information constituting the trip information on the display unit 190. The coordinates corresponding to each probe information are mapped to a map by converting into coordinate information on the screen. Then, the result display unit 154 draws a path so as to connect the mapped points and draw an arrow toward the arrival point (S122). Thereby, the inflow situation of the vehicle etc. to the area designated by the user can be displayed. Thereafter, the result display unit 154 shifts to a state of waiting for designation of an area (S123).
In addition, according to the user's designation input from the input unit 180, unnecessary ones of the traces drawn by the result display unit 154 may be individually deleted.

FIG. 11 shows a flowchart of an example of search processing by the next coordinate acquisition search method in the probe information providing server 200.
When the request reception unit 281 receives a search request from the user terminal 100 (S211), the probe search unit 284 searches the probe information DB 240 based on the area information and time range information included in the search request (S212). ). Specifically, the probe search unit 284 selects a trip whose probe information at the start of the trip belongs to a designated area and is within a designated time range. If there is one or more corresponding trips (S213: Yes), the probe search unit 284 displays the latitude information and longitude information of the probe information indicating the end of each trip (the stop position of the vehicle etc. and the destination). As a key, the POI DB 230 is searched for POI information existing at a position closest to the position indicated by the latitude information and longitude information (S214). And the response response part 283 transmits each probe information and POI information contained in the searched trip information to the user terminal 100 as a search result (S215).
On the other hand, when there is no corresponding trip (S213: No), the response response unit 283 transmits information that there is no POI information to the user terminal 100 as a search result (S215).
It should be noted that regarding the POI information search, a condition may be set such that the POI information is not located at the nearest position but is targeted for POI information located within a radius Xm from the end of the trip.

FIG. 12 shows a flowchart of an example of a process for displaying a search result by the next coordinate acquisition search method in the user terminal 100.
When the response reception unit 156 receives the search result from the probe information providing server 200 (S221), the result display unit 154 determines whether or not the search result includes POI information (S222). If POI information is included, the search results also include trip information about trips that end at a position close to the latitude information and longitude information specified by the POI information.
If the POI information is not included in the search result (S222: No), it means that there is no POI information related to the designated survey area, so that the result display unit 154 does not perform display processing and waits for designation of the area. Transition is made (S224).
On the other hand, when the POI information is included in the search result (S222: Yes), the result display unit 154 displays the latitude information and longitude information included in the individual probe information constituting the trip information on the display unit 190. The coordinates corresponding to each probe information are mapped to a map by converting into coordinate information on the screen. Then, the result display unit 154 connects the mapped points, draws a trajectory toward the arrival point, and draws POI information around the arrival point together (S223). Thereafter, the result display unit 154 shifts to a state of waiting for designation of an area (S224).
In addition, according to the user's designation input from the input unit 180, unnecessary ones of the traces drawn by the result display unit 154 may be individually deleted. It is also possible to draw only the POI information and not display the trip locus, and when there is duplicate POI information, it may be ranked and displayed according to the number of cases.

  In the above embodiment, the user terminal (in-vehicle terminal) 100 collects probe information for one trip, but the user terminal (in-vehicle terminal) 100 collects probe information together with information for identifying itself as a probe information providing server. The probe information providing server 200 may add the trip ID to the probe information for one trip of each user terminal (vehicle terminal) 100 to create the trip information.

In the above embodiment, in the next coordinate acquisition search method, the probe information providing server 200 searches the probe information DB 240 for probe information such as a vehicle headed to a surrounding destination from the designated area.

  In the above embodiment, the probe information transmission program 140 and the probe information reception program 150 are stored in the memory 130. However, only one of the probe information transmission program 140 and the probe information reception program 150 is stored in the memory 130. The CPU 120 may execute only one of the probe information transmission program 140 and the probe information reception program 150.

As described above, according to the present invention, probe information useful for finding a minor facility or small spot that is not yet known or presenting a currently popular facility or spot near an area is provided in real time. be able to.
Specifically, by searching for probe information using the area approach probe acquisition search method, the user can know how much the vehicle or the like that has flowed into the designated area has moved from which direction.
For example, when conducting sales to new customers or area marketing for new store openings, etc., by analyzing the probe information searched by the area entry probe acquisition search method, from where to how many to the specified area It is possible to present to the user information indicating in which time zone many vehicles and the like are coming. For this reason, the user can perform sales and area marketing efficiently.
Furthermore, when the inflow amount of vehicles or the like to the designated area is large, for example, there may be a popular facility or a popular spot that is not registered in the POI information DB 230 in the area. For this reason, users find the latest popular spots that are not yet reflected in the normal navigation system, or they are not included in the map at minor facilities or small spots, so they can be searched for in the normal navigation system. You can discover new facilities that are not included or that you do not know.
In addition, according to the next coordinate acquisition search method, a place (a popular spot or a recommended spot registered in the POI information DB 230) that is visited most often from a certain area (for example, an amusement park parking lot) is given to the user. Can be proposed. Further, by analyzing the trip information, it is possible to propose a route and a required time to that point.

  Although the embodiments of the present invention have been described above, various modifications and combinations necessary for design reasons and other factors are described in the inventions described in the claims and the specific embodiments described in the embodiments of the invention. It is included in the scope of the invention corresponding to the example.
