The information stored corresponding to the item “performer name” is information indicating the performer of the program in which the POI is introduced.

(processing)
Next, processing executed by the program information guide device 1 configured as described above will be described. This process is roughly divided into a program information registration process and a guidance control process. It should be noted that the control unit 60 of the program information guide device 1 performs control that is not specified.

(Processing-Program information registration process)
First, the program information registration process will be described. FIG. 3 is a flowchart of the program information registration process (in the following description of each process, step is abbreviated as “S”). This program information registration process is a process for storing program information designated by the user as registered program information in the program information DB 72. For example, the program receiving unit 20 receives a program based on an instruction input via the operation unit 10. Is started and output of the program is started via the display 50 and the speaker 40, the program is repeatedly activated at a predetermined cycle.

  When the program information registration process is started, the program information acquisition unit 62 acquires the program incidental information of the program received by the program reception unit 20 (SA1), and whether the program incidental information includes information on POI or not. Is determined (SA2). Here, “POI information” includes, for example, “POI ID”, “POI name”, “address”, “broadcast station name”, and “broadcast time”.

  As a result, when the information regarding POI is not included (SA2, No), it is determined that the program is not registered for program information, and the control unit 60 ends the program information registration process.

  On the other hand, when the information associated with POI is included in the program accompanying information (SA2, Yes), the control unit 60 determines whether or not the program accompanying information is designated to be registered by the user (SA3). For example, when a registration button is superimposed on the display 50 that is outputting a program and the registration button is pressed by the user, it is determined that the program accompanying information of the program is designated to be registered by the user. Alternatively, when the program incidental information satisfies a condition preset by the user (for example, when the “broadcasting station name” of the program incidental information matches the broadcasting station name preset by the user) It is determined that the program accompanying information of the program is designated to be registered by the user.

  As a result, when the program accompanying information is not designated to be registered by the user (SA3, No), it is not necessary to register the program accompanying information, and the control unit 60 ends the program information registration process.

  On the other hand, when the program accompanying information is specified to be registered by the user (SA3, Yes), the control unit 60 stores the program accompanying information in the program information DB 72 as registered program information (SA4). Thereafter, the control unit 60 ends the program information registration process.

(Processing-Guidance control processing)
Next, the guidance control process will be described. FIG. 4 is a flowchart of the guidance control process. This guidance control process is a process for guiding the registered program information, and is started when the power of the program information guidance device 1 is turned on, for example.

  When the guidance control process is started, the guidance control unit 64 refers to the program information DB 72 and determines whether or not there is registered program information that has been stored in the program information DB 72 and for which the number of days equal to or greater than a threshold has elapsed ( SB1). The method for specifying the number of days elapsed since the program information DB 72 was stored is arbitrary. For example, the number of days from the “registration date” included in the registered program information to the present is used as the number of days elapsed. This threshold is the number of days that the user may forget that he / she has registered the registered program information after registering the registered program information, and guides the registered program information to the user after the number of days has passed. Thus, the number of days effective for reminding the user that the registered program information has been registered is set, for example, six months is set. Here, the determination is performed in units of days. However, determination may be performed in units of hours. In this case, for example, the registration program information stores the POI registration date and time, and this registration is performed. It may be determined whether the time from the date and time to the current date and time is the elapsed time and a time equal to or greater than a threshold has elapsed.

  As a result, if there is no registered program information that has been stored in the program information DB 72 and the number of days greater than or equal to the threshold has elapsed (SB1, No), it is assumed that it is not the timing to guide the registered program information, and the guidance control unit 64 provides guidance. The control process ends.

  On the other hand, when there is registered program information that has been stored in the program information DB 72 and the number of days equal to or greater than the threshold has elapsed (SB1, Yes), the road information acquisition unit 61 acquires the traffic jam road information and the traffic jam cause information ( SB2). Here, “congested road information” is information for specifying a road in a traffic jam, and “congestion cause information” is information for specifying the cause of the traffic jam. The road information acquisition unit 61 acquires the traffic jam road information and the traffic jam cause information based on traffic information distributed from a known information center (not shown), for example. Alternatively, it is possible to obtain information on traffic jams by image analysis for video information included in program main body information, voice analysis for audio information included in program main body information, character recognition or language analysis for program incidental information, etc. And traffic jam cause information may be acquired.

  Next, the guidance control unit 64 identifies a road in a traffic jam based on the traffic jam road information acquired by the road information acquisition unit 61. Further, the cause of the traffic jam in the traffic jam is identified based on the traffic jam cause information acquired by the road information acquisition unit 61, and the traffic jam is identified due to a cause other than an accident or construction (SB3).

  Subsequently, the position specifying unit 63 specifies the position of the POI included in the registered program information for which the time equal to or greater than the threshold has elapsed since being stored in the program information DB 72 (SB4). For example, the position specifying unit 63 specifies the position of the POI based on the “address” included in the registered program information.

  Next, the guidance control unit 64 specifies the percentage of roads in a traffic jam within a predetermined range including the POI position based on the traffic jam road specified in SB3 and the POI position specified in SB4. Then, the registered program information corresponding to the POI having the specified traffic jam in the ratio of the road having a threshold value or more is selected (SB5). Here, the “predetermined range including the position of the POI” is a range in which traffic congestion can occur due to the POI, for example, a range within a radius of 10 km centered on the POI. In addition, “the ratio of roads in a traffic jam” is, for example, the number of all road links existing within a predetermined range including the POI position, and the number of road links in a traffic jam among all the road links is divided. You can ask for it. Alternatively, the determination may be performed based on the number of roads as an aggregate of a predetermined number of road links instead of the number of road links. For example, the number of roads existing in a predetermined range including the POI position may be used. , By dividing the number of congested roads among all the roads. Further, the total length of the road links of all roads existing within a predetermined range including the POI position is divided by the total length of the road links of the roads that are congested among all the roads. it can. Or it can obtain | require by dividing the total length of the road in congestion among all the said roads by the total length of all the roads which exist in the predetermined range including the position of POI. Further, the specific value of the “threshold value” of the percentage of roads in a traffic jam is arbitrary, and for example, 20% is set as the threshold value.

  FIG. 5 is a diagram illustrating a road link in a traffic jam within a predetermined range including the POI position. In the example of FIG. 5, the number of road links in a traffic jam in a predetermined range including “POI1” (the range surrounded by a dotted line) is 7, and the number of road links in a traffic jam in a predetermined range including “POI2” is 2, The number of road links in a traffic jam in a predetermined range including “POI3” is four. When the number of all road links included in this predetermined range is 10 (however, the links of roads that are not congested are not shown), the ratio of the number of road links in the predetermined range including “POI1” is 70. %, The ratio of the number of road links in traffic congestion in the predetermined range including “POI2” is 20%, and the ratio of the road links in traffic congestion in the predetermined range including “POI3” is 40%. Since the percentage of roads that are congested is greater than or equal to the threshold, registered program information corresponding to these POIs is selected.

  Returning to FIG. 4, the guidance control unit 64 specifies the change rate of the traffic jam within the predetermined range including the POI position specified in SB4 based on the traffic jam road information acquired by the road information acquisition unit 61 in SB2. Then, registered program information corresponding to a POI having a specified rate of change equal to or greater than a threshold is selected (SB6).

  Here, the “change rate of traffic jam” is a numerical value representing a change in the level of traffic jam. For example, the guidance control unit 64 counts the number of roads jammed in one day within a predetermined range including the POI position specified in SB4 based on the traffic jam road information, and records it in the data recording unit 70. Keep it. Then, the increase / decrease in the number of roads congested in one day within a predetermined period is specified as “congestion change rate”. In this case, for example, when the number of roads congested during one day increases or decreases by five or more in one week up to the current day, it is determined that the change rate of the congested traffic is greater than or equal to the threshold value.

  Alternatively, the guidance control unit 64 aggregates the daily average values of the degree of congestion on all roads within a predetermined range including the POI position specified in SB4 on a daily basis based on the congestion road information, and records it in the data recording unit 70 Keep it. Here, the “congestion degree” is an index indicating the degree of traffic jam. For example, when the average vehicle speed on the road is 10 km / h or less (congestion), “3”, the average vehicle speed is 10 km / h or more and less than 20 km / h (congestion) ) In the case of “2”, and “1” in the case where the average vehicle speed is 20 km / or more (smooth). The increase / decrease of the average value of the congestion level within a predetermined period is specified as the “change rate of congestion”. In this case, for example, when the average value of the degree of congestion is increased or decreased by 1 or more in one week up to the current day, it is determined that the change rate of the congestion is equal to or more than a threshold value.

  FIG. 6 is a diagram exemplifying a change in traffic jam within a predetermined range including the position of POI. FIG. 6A is a diagram showing a traffic jam change within a predetermined range including the position of “POI1”. b) is a diagram showing a change in traffic jam within a predetermined range including the position of “POI2”. FIG. 6 illustrates a case where the change rate of the traffic jam is the increase / decrease of the number of roads jammed during the day (the number of road links) within a predetermined period. According to FIG. 6, the change rate of the traffic jam in the predetermined range including POI 1 is “6 increase in one week until the current day”. Therefore, it is determined that the value is equal to or greater than the threshold value of “5 or more changes in one week until the current date”. Further, the change rate of the traffic jam in the predetermined range including POI2 is “7 decrease in one week until the current day”. Therefore, this is also determined to be equal to or greater than the threshold value of “increase or decrease by 5 or more in one week until the current date”.

  Returning to FIG. 4, the guidance control unit 64 determines whether there is registered program information selected in SB5 or SB6 (SB7). As a result, when there is no selected registered program information (SB7, No), it is assumed that there is no need to perform guidance, and the guidance control unit 64 ends the guidance control processing.

  On the other hand, when there is registered program information selected in SB5 or SB6, the guidance control unit 64 determines whether or not a plurality of registered program information is selected in SB5 and SB6 (SB8). As a result, when a plurality of registered program information is selected (SB8, Yes), the guidance control unit 64 determines the ratio of roads in a traffic jam within a predetermined range including the POI position, or the rate of change in traffic jams in that order. The registered program information corresponding to the POI is rearranged (SB9).

  When a plurality of registered program information is not selected in SB5 and SB6 (that is, when one registered program information is selected) (SB8, No), or after the processing of SB9, the guidance control unit 64 selects the selected registration. Control for guiding program information is performed (SB10). FIG. 7 is a diagram illustrating a display 50 on which registered program information is output based on control by the guidance control unit 64. The specific content of the control by the guidance control unit 64 is arbitrary. For example, as shown in FIG. 7A, the “POI name” included in the registered program information selected in SB5 or SB6, or the POI from the current position. And the like are displayed on the display 50. When a plurality of registered program information is selected in SB5 and SB6, the registered program information may be displayed in the order rearranged in SB9. By performing such a display, it is possible to remind the user of the existence of registered program information registered in the past.

  When a plurality of registered program information is selected in SB5 and SB6, as shown in FIGS. 7B to 7D, the “POI name” included in the registered program information is displayed. 50 may be displayed as a list. FIG. 7B shows the registered program information selected in SB5. FIG. 7C shows the registered program information selected in SB6 with the change rate (increase tendency) of the traffic jam being the threshold value or more. In this case, FIG. 7 (d) shows a case where the registered program information is selected in which the change rate (decrease tendency) of the traffic jam is selected as the threshold value or more in SB6. In this case, the guidance control unit 64 performs control so that the registered program information is displayed in the order rearranged in SB9.

  For example, by guiding the registered program information selected in SB5 as shown in FIG. 7B, it is possible to guide POIs in which many of the surrounding roads are congested, that is, POIs that are considered to be popular. Further, as shown in FIG. 7 (c), by guiding the registered program information in which the change rate (increase tendency) of the traffic jam is selected as the threshold value or more in SB6, the POI in which the traffic jam is increasing on the surrounding road, that is, the popularity increases. It is possible to guide the POI that is coming and is considered to be the season. Further, as shown in FIG. 7 (d), by guiding the registered program information in which the change rate (decrease tendency) of the traffic jam is selected as the threshold value or more in SB6, the POI in which the traffic jam is decreasing on the surrounding road, that is, the peak of popularity It is possible to guide a POI that is considered to have passed and can be reached without being bothered by traffic jams in the season.

  Further, in addition to the display on the display 50, guidance that the registered program information including the POI suitable for a holiday destination is stored in the program information DB 72 may be output from the speaker 40.

  Returning to FIG. 4, after performing control for guiding the registered program information in SB10, it is determined whether or not an operation related to POI (hereinafter referred to as POI operation) included in the guided registered program information is instructed (SB11). ). For example, a POI operation menu for causing the user to select a desired POI operation from a plurality of predetermined POI operations is displayed on the display 50. The specific contents and method of this POI operation are arbitrary. For example, when the program information guide device 1 is applied to a car navigation device, the purpose is to set the POI included in the registered program information that has been guided to the destination. For example, a location setting operation, a map display operation around the POI, a detailed information display operation of the POI, or an edit deletion operation for editing or deleting the POI can be given. If any POI operation is selected by the user via the operation unit 10 in the POI operation menu displayed on the display 50 in this manner, it is determined that the POI operation is instructed.

  As a result, if it is determined that the POI operation instruction has not been given (No in SB11), it is not necessary to provide further guidance for the registered program information guided in SB10, and the guidance control unit 64 ends the guidance control process. .

  On the other hand, when it is determined that the POI operation instruction has been given (SB11, Yes), the guidance control unit 64 performs a process according to the instructed POI operation (SB12), and ends the guidance control process. For example, when a destination setting operation is instructed as a POI operation, a known route search means (not shown) searches for a travel route with the POI set as the destination and guides the travel route.

(effect)
As described above, according to the first embodiment, the road in the traffic jam specified based on the traffic jam road information acquired by the road information acquisition unit 61 and the location included in the registered program information designated to be registered by the user. Based on the location, the registered program information stored in the program information DB 72 is selected, and control for guiding the selected registered program information is performed. Registered program information regarding the place can be guided. As a result, even if the user himself / herself does not remember that the place introduced in the program is registered, information on the place can be guided at an appropriate timing, and the registered information can be used effectively. it can.

  In particular, since the number of roads in a traffic jam within a predetermined range including the position of the location included in the registered program information is specified, and the registered program information stored in the program information DB 72 is selected based on the specified number, For example, it is possible to select registered program information regarding a place where traffic congestion has occurred on many of the surrounding roads. Thereby, it is possible to guide information regarding a place that is particularly popular and considered to be seasonal, and can guide information useful to the user.

  In addition, since the change rate of the traffic jam within a predetermined range including the position of the place included in the registered program information is specified, and the registered program information stored in the program information DB 72 is selected based on the specified change rate, for example, Information on places where traffic congestion is increasing on the surrounding roads, that is, places that are increasing in popularity and are considered to be in the future, can be provided. Alternatively, it is possible to provide information on a place where traffic congestion is decreasing on the surrounding road, that is, the peak of popularity has passed and it is possible to arrive without being bothered by traffic congestion in the season. Thereby, useful information for a user can be guided.

  Further, the cause of the traffic jam in the traffic jam is identified based on the traffic jam cause information acquired by the road information acquisition unit 61, and the registered program information stored in the program information DB 72 is stored on the basis of the identified traffic jam cause. Therefore, the registered program information can be selected based on only the traffic jam that is highly likely to have occurred due to the place. Therefore, it is possible to reliably select the registered program information regarding the seasonal place.

  Moreover, since traffic jam road information is acquired based on the program information acquired by the program information acquisition part 62, the newest traffic jam road information can be acquired and useful information for a user can be guided.

  In addition, since only registered program information for which a time equal to or greater than the threshold has elapsed since being stored in the program information DB 72 is selected, the registered program that the user has remembered himself / herself is short in elapsed time since viewing by the user. Information can be excluded from guidance. Therefore, the registered program information can be guided at a timing that is not complicated for the user.

[Embodiment 2]
Next, a second embodiment will be described. In the second embodiment, the registered program information stored in the program information storage means is selected based on the newly established road and the location of the place included in the registered program information. The configuration of the second embodiment is substantially the same as the configuration of the first embodiment, unless otherwise specified. The same configuration as that of the first embodiment is used in the first embodiment. The same reference numerals and / or names as those used are attached as necessary, and description thereof is omitted.

  In SC1, when there is registered program information that has been stored in the program information DB 72 and the number of days greater than or equal to the threshold has elapsed (SC1, Yes), the road information acquisition unit 61 acquires new road information (SC2). Subsequently, the guidance control unit 64 specifies a newly established road based on the newly established road information acquired by the road information acquiring unit 61 (SC3).

  After identifying the position of the POI included in the registered program information for which the number of days greater than or equal to the threshold has elapsed since it was stored in the program information DB 72 in SC4, the guidance control unit 64 detects the newly established road identified in SC3, the SC4 The number of newly established roads within a predetermined range including the POI position is specified based on the POI position specified in (1). Then, the registered program information corresponding to the POI having the specified number of newly established roads greater than or equal to the threshold is selected (SC5). Here, the “predetermined range including the position of the POI” is, for example, a range in which some of the roads in the range can affect the convenience when accessing the POI, for example, within a radius of 10 km centered on the POI. A range. As the “number of newly established roads”, for example, the number of road links of newly established roads is used. Further, the specific value of the “threshold value” for the number of newly established roads is arbitrary, and for example, one is set as the threshold value.

  FIG. 9 is a diagram illustrating a newly established road within a predetermined range including the position of the POI. In the example of FIG. 9, the number of newly established roads in the predetermined range including “POI1” (the range surrounded by the dotted line) is 7, and the number of newly established roads in the predetermined range including “POI2” is 2. The number of newly established roads in the predetermined range including “POI3” is four. When the threshold value for the number of newly established roads is two, the number of newly established roads for all of these POIs is equal to or greater than the threshold value, so that registered program information corresponding to these POIs is selected.

  In SC7, when it is determined that a plurality of registered program information is selected in SC5 (SC7, Yes), the guidance control unit 64 sets the POI in the order of the number of newly established roads within a predetermined range including the position of the POI. The corresponding registered program information is rearranged (SC8).

  When a plurality of registered program information is not selected in SC5 (that is, when one registered program information is selected) (SC7, No), or after the processing of SC8, the guidance control unit 64 selects the selected registered program information. (SC9). FIG. 10 is a diagram illustrating a display 50 on which registered program information is output based on control by the guidance control unit 64. The specific content of the control by the guidance control unit 64 is arbitrary. For example, as shown in FIG. 10, a list of “POI names” included in the registered program information is displayed on the display 50. In this case, the guidance control unit 64 performs control so that the registered program information is displayed in the order rearranged in SC8. By performing such a display, it is possible to remind the user of the existence of registered program information registered in the past.

(effect)
As described above, according to the second embodiment, the new road specified based on the new road information acquired by the road information acquisition unit 61 and the location included in the registered program information designated to be registered by the user are described. The location where the registered program information stored in the program information DB 72 is selected on the basis of the location and the control for guiding the selected registered program information is performed. It is possible to guide the registered program information regarding. Thus, it is possible to remind the user who registered the information about the place introduced in the program that there is information registered in the past.

  In particular, since the number of newly established roads within a predetermined range including the position of the place included in the registered program information is specified, and the registered program information stored in the program information DB 72 is selected based on the specified number, For example, it is possible to select registered program information regarding a place where many roads are newly established in the vicinity. As a result, it is possible to guide information related to a place that is considered to have been developed and easily accessed, and information useful to the user can be guided.

  Moreover, since new road information is acquired based on the program information acquired by the program information acquisition part 62, the newest new road information can be acquired and useful information for a user can be guided.
