The recruitment of the monitor can be performed using, for example, a paper medium. In this case, the second server 7 is not necessary.

FIG. 5 is a block diagram showing an outline of the functions of the mobile phone 3.
The mobile phone 3 includes a position measuring unit 51, a time measuring unit 52, a probe data transmitting unit 53, and the like.

  The position measuring unit 51 measures position information. The position measuring means 51 is, for example, a GPS (Global Positioning System) function. The position measuring means 51 receives a signal from an artificial satellite and calculates position information (latitude information and longitude information) by a known technique.

  The time measuring means 52 measures time information. The time measuring means 52 is a clock function built in the mobile phone 3.

  The probe data transmission unit 53 transmits probe data including a user ID for specifying a monitor, position information, and time information to the first server 5. Here, the probe data is generally data transmitted from a vehicle called a probe car, and includes, for example, vehicle position information, vehicle speed information, vehicle behavior information such as wiper movement, and the like. However, in the embodiment of the present invention, it is assumed that the data is not data transmitted from the vehicle but data transmitted from the mobile phone 3 and includes position information and time information. The probe data may further include image data, character data, and the like.

  The probe data transmission unit 53 acquires position information from the position measurement unit 51, acquires time information from the time measurement unit 52, adds a predetermined user ID, and transmits the probe data to the first server 5 as probe data. . Here, it is desirable that the probe data is compressed and further transmitted together. For example, the probe data transmission unit 53 converts the numerical values such as time information and position information to 60, and further compresses the data using a difference number or NULL data in order to avoid duplication of data. Further, for example, the probe data transmission unit 53 measures the compressed probe data measured at a predetermined time interval (for example, every second) and stores the compressed probe data in the mobile phone 3 until a predetermined time (for example, 1 minute) elapses. 23 is accumulated and transmitted in a batch. As a result, it is possible to reduce the load and time required for transmitting probe data.

Note that the probe data transmission means 53 is not included in the mobile phone 3 in advance. Therefore, the person who becomes the monitor needs to install a program for realizing the function of the probe data transmission means 53 in the mobile phone 3. This may be downloaded and installed from the program providing location described above with reference to FIG.
Further, by downloading a setting file related to the probe data transmission method and transmission contents together with the program, the survey requester can determine the probe data transmission method and transmission contents. That is, the probe data transmission means 53 determines the probe data transmission method and transmission contents according to the setting file. Here, the transmission method includes a data measurement time interval, a data transmission time interval, a data transmission interruption / resumption, and the like. The contents of the transmission include user ID, picture quality, and operation button definition (for example, in the case of facility evaluation questionnaire, “1” button is “Evaluation A: Very interesting”, “2” button. Means “evaluation B: so-so interesting” or the like. Further, the probe data transmission unit 53 updates the contents of the setting file in accordance with an instruction from the first server 5, and changes the probe data transmission method and transmission contents. As a result, the survey requester can obtain a desired survey result without imposing a load on the monitor.

  And since the mobile phone 3 having a GPS function and a clock function is generally widely used, a person who becomes a monitor may participate in a movement history survey using the mobile phone 3 that is usually used. it can. Therefore, an investigation dedicated terminal for conducting a movement history investigation is not necessary. Furthermore, since the mobile phone 3 is always carried around, for example, a movement history survey can be performed even after a monitor that has been in a car gets off the car.

FIG. 6 is a block diagram showing an outline of functions of the first server 5.
The first server 5 includes probe data conversion means 61, movement history information provision means 62, traffic information generation means 63, traffic information provision means 64, movement pattern information generation means 65, movement pattern information provision means 66, probe data DB ( Database) 71, DRM (Digital Road Map) data DB 72, travel time data DB 73, and the like.

FIG. 7 is a diagram in which probe data is arranged on a road map.
A plot 101 is position information included in the probe data. As shown in FIG. 7, the plot 101 varies depending on a GPS measurement error or the like. However, unless the movement path of each monitor is specified in consideration of such variations, it cannot be used for various investigations. In the embodiment of the present invention, the probe data conversion means 61 specifies the movement path of each monitor.

  The probe data conversion means 61 specifies a travel route from the probe data transmitted from the mobile phone 3 and converts it into travel time data. The probe data conversion means 61 refers to the probe data DB 71 that stores the probe data transmitted from the mobile phone 3 and the DRM data DB 72 that holds the DRM data, and specifies the movement path by matching the probe data with the DRM data. The travel time data is written in the travel time data DB 73.

FIG. 8 is a diagram showing DRM data.
As shown in FIG. 8, the DRM data is expressed by a combination of the node 102 and the link 103. The node 102 is an intersection or other nodal point. A link 103 is a road section between the node 102 and the node 102. Each node 102 is given a node number that uniquely identifies it. Similarly, each link 103 is given a unique link number. The DRM data is generally commercially available.
In the embodiment of the present invention, the movement path is specified by using the distance between each plot 101 and the link 103 and the movement direction in each plot 101.

FIG. 9 is a diagram showing the moving direction 104 in each plot 101.
As shown in FIG. 9, the probe data conversion means 61 identifies the subsequent plot 101 in each plot 101 based on the time information included in the probe data, and connects the coordinates of the subsequent plot 101 from the coordinates of each plot 101. A straight line is determined as the moving direction 104.

FIG. 10 is a diagram showing a perpendicular 105 to the nearest link from each plot 101.
The probe data conversion means 61 extracts links 103 that exist within a certain distance from each plot 101. When a plurality of links 103 are extracted, the link 103 having the direction closest to the calculated moving direction 104 is determined as the nearest link. Then, as shown in FIG. 10, the perpendicular line 105 to the nearest link is drawn from the plot 101, and the plot 106 on the link is determined.

FIG. 11 is a diagram illustrating the movement route 107.
As shown in FIG. 11, the probe data conversion means 61 identifies the movement path 107 from the plot 106 on the link. At that time, the traveling direction 108 in each link 103 is also specified. Then, for each link 103, travel time data is calculated and written in the travel time data DB 73. The travel time data includes a user ID, a link number, a link entry time, a link exit time, a link required time, an intra-link movement speed, and the like. Further, the probe data conversion means 61 further processes the travel time data and arranges the user ID, the departure point, the departure time, the arrival point, the arrival time, the movement route (for example, in chronological order) for each identified movement route. The travel history information including the node number or link number) and travel time may be written in the travel time data DB 73. When specifying the movement route, even if it is the same monitor, if the data acquisition interval is longer than a certain time (for example, moving with a break, etc.), another movement route is used. deal with.
In the following description, it is assumed that the travel history information is written in the travel time data DB 73. However, the travel time data may be processed to obtain travel history information each time the travel time data DB 73 is referred to.

  The travel history information providing means 62 refers to the travel time data DB 73 and provides travel history information based on the travel time data. In the embodiment of the present invention, the movement history information is provided by, for example, a map-based bulletin board. Specifically, the movement history information providing unit 62 can transmit a web page displaying a map-based bulletin board via the Internet.

FIG. 12 is a diagram showing an example of a map-based bulletin board.
As shown in FIG. 12, the map-based bulletin board includes a region 214 for displaying a map and a region 215 for displaying a bulletin board. In FIG. 12, a point 212 and a message 213 are displayed in a region 214 for displaying a map. The point 212 and the message 213 are those transmitted from the mobile phone 3 held by the moving monitor or added from the web page. The mobile phone 3 can transmit image information together with the position information of the point 212 and the character information of the message 213. Alternatively, the questionnaire may be answered at the point 212 instructed in advance by the research subject, and the answer result may be transmitted.

Reference numerals 207 to 211 denote panel groups for operating the bulletin board. In FIG. 12, the selected panel 211 is open. The icon type panel 207 displays a legend of icons that can be displayed as points 212 on the map, and can add, edit, and delete icons. A message panel 208 provides a general bulletin board function. The My Points panel 209 displays points 212 registered by the logged-in user. When one of the displayed points 212 is selected, the point 212 is moved to a location centered on the point 212 in conjunction with the area 214 for displaying the map. The point panel within the range of 210 displays the point 212 currently displayed on the map. The 211 recent message panel displays a predetermined number of the latest messages 213. When one message 213 is selected, it moves to a location centered on the point 212 to which the message 213 is added in conjunction with the map display area 214.

FIG. 13 is a diagram illustrating an example of display of movement history information.
When the tool 204 for displaying past movement history information shown in FIG. 12 is selected, movement history information 301 is displayed in a region 214 for displaying a map, as shown in FIG. The movement history information 301 is a set of travel time data from the start point 302 to the end point 303. A detailed information message 304 of the movement history information 301 is added to the end point 303. The detailed information message 304 includes a user name, date and time, a time limit of displayed data, a memo, and the like.
Similarly, when the tool 205 for displaying the movement history information of the currently moving monitor shown in FIG. 12 is selected, the movement history information 301 from the starting point 302 to the current point is displayed. The displayed data is updated every minute, for example, and moves to a location centered on the latest data acquisition position at the update timing.
As described above, the movement history information providing means 62 can provide the movement history information by the map-based bulletin board, thereby providing the character information and the image information linked with the map. In particular, when a survey subject conducts a questionnaire, the questionnaire result can be confirmed in conjunction with a map. Furthermore, the movement history information can be confirmed in real time.

  The traffic information generating unit 63 generates traffic information based on the travel time data. Here, the traffic information is traffic jam information or shortest route information determined by information obtained by processing travel time data. Hereinafter, generation of the shortest path information in consideration of the movement time zone will be described in particular.

FIG. 14 is a diagram illustrating an example of a search screen for shortest path information.
As illustrated in FIG. 14, the shortest path information search screen 401 includes an area 402 for inputting a date search condition, an area 403 for inputting a time search condition, an area 404 for inputting a search condition for a required time, and the number of searches. A search condition input area 405, a user ID search condition input area 406, a search button 407, a close button 408, and the like are included.

In the area 402 for inputting the date search condition, the date of the movement history information to be searched is input. Specifically, the search range is input to 402a and 402a, and the search day of the week is input to 402c. In the example shown in FIG. 14, the search range is input from January 01, 2007 to January 03, 2007, and the search day is input as daily.
In a region 403 for inputting a time search condition, a time zone of movement history information to be searched is input. Specifically, the search time zone is input to 403a and 403b. In the example shown in FIG. 14, the search range is input from 07:00 to 3 hours.
In the area 404 for inputting the search condition for the required time, the required time of the movement history information to be searched is input. Specifically, the time required for searching is input in 404a. In the example shown in FIG. 14, the time required for the search is input within 30 minutes.
In the area 405 for inputting the search number search condition, the number of searches for the movement history information to be searched is input. Specifically, the number of searches to be searched is input to 405a. In the example shown in FIG. 14, the number of searches to be searched is input up to three people.
In the area 406 for inputting the search conditions for the user ID, the user ID of the movement history information to be searched is input. Specifically, after the user ID to be searched is input to 406a, the button 406c is pressed and reflected in 406e. Alternatively, after selecting a user ID to be searched from the user IDs displayed on 406b, the user presses the button 406c to reflect it on 406e. On the other hand, to remove the user ID displayed in 406e from the search target, 406d is pressed. In the example shown in FIG. 14, the user ID to be searched is not input, and the search condition does not limit the user ID.

When the search button 407 is pressed, a message prompting the user to specify the start point and end point of the movement history information to be searched is displayed on the map. When the start point and the end point are designated, the search is started based on the input search condition.
When the close button 408 is pressed, the shortest path information search screen 401 is closed.

The traffic information generation means 63 searches the travel time data DB 73 based on the input search conditions, extracts travel history information that matches the search conditions, and generates the shortest route information arranged in the order of the short travel time.
The conventional shortest route search does not consider the traffic conditions that differ depending on the travel time zone, and for example, the travel route of the shortest required time is searched by accumulating the link required time calculated from the link distance and the legal speed in the link. . On the other hand, in the shortest route search according to the present embodiment, travel history information that matches the designated travel time zone is extracted from the travel time data DB 73 in which past travel histories are accumulated. Thereby, the shortest route information in consideration of different traffic conditions for each movement time zone can be generated based on past results. A search in which the user ID is added to the search condition is also effective. For example, by accumulating daily commuting history and performing a search by specifying only its own travel history information, the optimal departure time and travel route for each day of the week can be determined. Further, for example, if a search is performed by specifying only the movement history information of a taxi driver, it is possible to know the optimum movement route selected by the driving expert.

  The traffic information providing unit 64 provides the traffic information generated by the traffic information generating unit 63. In the following, in particular, provision of traffic information generated by the example shown in FIG. 14 will be described.

A search condition display area 502 displays the search condition input on the search screen 401 for the shortest path information. In the example shown in FIG. 15, the search conditions shown in FIG. 14 are displayed.
The area 503 for displaying the shortest route information displays the traffic information generated by the traffic information generating means 63. Specifically, the user ID 503b, the departure time 503d, the arrival time 503e, and the movement time 503f of the shortest route information arranged in ascending order of the movement time are displayed. Reference numeral 503a is a check box that displays whether or not the item is selected, and performs processing in conjunction with the button. In the example illustrated in FIG. 15, the traffic information with the user ID 503b “user1” and “user2” is selected. A color 503c is a display color when the moving route is displayed on the map. In the example shown in FIG. 15, the difference in color is expressed by the difference in pattern.

As shown in FIG. 16, on a screen 511 displaying a movement route on a map, a symbol 512 representing the start point and a symbol 513 representing the end point of the movement history information to be searched are displayed. Further, when the display button 507 on the search result display screen 501 shown in FIG. 15 is pressed, movement paths 514 and 515 having the selected user ID 503b of “user1” and “user2” are displayed.

  In this way, the traffic information providing means 64 displays the shortest route information arranged in the order of the shortest travel time, and further displays the travel route on the map. As a result, the shortest route can be confirmed while comparing the travel routes on the map.

The movement pattern information generation means 65 generates movement pattern information based on the travel time data. The movement pattern information is, for example, information obtained by analyzing what tourist attractions a tourist visits and what kind of sightseeing route in a tourist spot survey. In this case, the travel history information during the sightseeing is collected by having the tourist participate as a monitor.
The analysis content is, for example, the number of visits for each tourist attraction. In this case, for example, the movement pattern information generation unit 65 identifies the node located at the location of the tourist attraction, and refers to the travel time data DB 73 to count the number of monitors that have passed the identified node.
Another analysis content is, for example, the number of monitors for each sightseeing route. When the tourist spot is a round course, it is possible to analyze whether there are many tourists sightseeing in the clockwise direction or many tourists sightseeing in the counterclockwise direction. In this case, for example, the movement pattern information generation unit 65 specifies two nodes located on the circuit course, and refers to the travel time data DB 73 to extract a monitor that has passed through the two specified nodes. Further, it is determined which of the two specified nodes has passed first, and the number of monitors for each sightseeing route is totaled.
In the conventional sightseeing spot survey, the above-mentioned analysis was performed by conducting a questionnaire afterwards for tourists, but it was not accurate. On the other hand, in this embodiment, various analyzes are performed by referring to the travel time data DB 73 without depending on the memory of the tourist. Thereby, an accurate analysis result can be obtained.

  The movement pattern information provision unit 66 provides the movement pattern information generated by the movement pattern information generation unit 65. In the following, in particular, the provision of analysis contents in a sightseeing spot survey will be described.

FIG. 17 is a diagram illustrating an example of a movement pattern information provision screen.
In the example shown in FIG. 17, a tourist takes a sightseeing at a museum 602, an observation deck 603, a shrine 604, etc., starting from a station 601. Further, the tourist takes a sightseeing by either a sightseeing route A from the station 601 to the museum 602 or a sightseeing route B from the station 601 to the shrine 604.
The movement pattern information providing means 66 provides movement pattern information displayed on a map. In the example illustrated in FIG. 17, the movement pattern information includes the number of visits to the museum 602, the number of visits to the observation deck 603, the number of visits to the shrine 604, the number of tourists sightseeing through the sightseeing route A, and the number of tourists sightseeing through the sightseeing route B. .

  As described above, the movement pattern information providing unit 66 displays the movement pattern information on the map. Thereby, movement pattern information can be confirmed on a map.

  In the present embodiment, the first server 5 has all the functions shown in FIG. 6, but the movement history system 1 is configured using a plurality of servers having some of the functions shown in FIG. You can also.

  As described above, according to the embodiment of the present invention, the second server 7 recruits monitors for movement history investigations via the Internet. The applied monitor installs a program for realizing the function of the probe data transmission means 53 in the mobile phone 3 and participates in the movement history survey. Based on the probe data transmitted from the mobile phone 3, the first server 5 uses the distance between the probe data plot 101 and the DRM data link 103 and the moving direction 104 in the plot 101 to move the route 107. Is converted into travel time data, and travel history information based on the travel time data is provided. In addition, traffic information and movement pattern information corresponding to the survey contents are generated from the movement history information and provided.

  According to the embodiment of the present invention, even if a survey requiring accurate and large amount of movement history information is required, the cost can be greatly reduced and the monitor can be performed without burdening the information. Survey results can be provided quickly.

  As mentioned above, although suitable embodiment, such as a movement history investigation system concerning the present invention, was described, referring to an accompanying drawing, the present invention is not limited to such an example. 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 naturally belong to the technical scope of the present invention. Understood.
