Thereby, parking lot information is supplied to the entrance information utilization terminal device 30 side.

FIG. 8 is a flowchart showing an operation example (decoding processing example) of the entrance information utilization terminal device according to the embodiment of the present invention. The parking lot information (location reference information) transmitted from the entrance information providing device 10 side is received by the receiving unit 31 in the entrance information utilization terminal device 30 (step S31). The PO entry direction specifying unit 40 sets the entry information data number N to 1 (step S32), and identifies the entry based on the first entry information (position reference information) ( In step S33), the rearmost position of the standby vehicle train on the first entry is identified (step S34). Next, it is checked whether the entry has been identified for all the entrances (step S35), and if it is not finished V (if NO in step S35), the entry information data number N is incremented by 1 ( The process returns to step S36) and step 33. This identifies the second entry, for example.

[0057] ΡΟΙ · Implementation direction specifying unit 40, when the identification of all the entrances is completed (YES in step S35), the entry status information data including the entrance and the waiting situation (the last position and the waiting time) are obtained. Supply to the Information Utilization Department 50. The information utilization unit 50 synthesizes the parking lot position, entrance position, entrance position force, parking road entry direction, waiting road section, end position, waiting time, etc., on the map screen as the parking lot information utilization process. Display on the screen of the image display device, or (Step S37).

FIG. 9 is a flowchart showing an information utilization example (route search processing example) of the entrance information utilization terminal device according to the embodiment of the present invention. Here, as an example of using the parking lot information, an example of processing for searching for a route to the target parking lot based on the parking lot information is shown. The information utilization unit 50 sets the entry information data number N to 1 (step S51), and searches for an entry route to the parking lot using the first entry (step S52). If the departure place is set, the entrance route from the departure place to the parking lot is searched, and if the departure place is set, the current position is searched for the entry route to the parking lot. Here, the route search unit 52 searches for an entrance route to the parking lot entrance via the waiting road section. By going through the waiting road section, if there is a waiting vehicle, it will be guided to the end.

[0059] Next, it is checked whether the route search has been completed for all the incoming routes (step S53). If it has not been completed (NO in step S53), the route number N is incremented by 1 (step S54). ), Return to the process of step S52. When the route search is completed for all the incoming routes (YES in step S53), the evaluation value of each searched route is obtained, and the route with the good evaluation value is selected as the recommended route (recommended route) (step S55). . Then, with regard to the selected route, the approach direction, entrance route, waiting vehicle train, etc. are displayed on the screen with lines, figures, characters, etc. along with the map, or invoiced.

[0060] As a route evaluation criterion, for example, a criterion such as selecting a route with a low link cost as a route having a high evaluation value is used. This link cost includes the distance to the end of the parking lot entrance and waiting vehicle train on the route, the time to reach the end of the parking entrance and waiting vehicle train (predicted value), and the type of road used (high speed Including the use of roads) and the number of turns. At this time, it is also possible to obtain the time (predicted value) to reach the parking lot including the waiting time. Also, the total evaluation value may be obtained by weighting the distance and time. When outputting a route, the route with the best evaluation value may be set as the first route and presented. Alternatively, a plurality of routes having different entry routes may be displayed on the map screen so that a user can select a desired route.

[0061] As described above, as shown in FIG. 10, it is only necessary to calculate and display the queue route, the last position, the waiting time, and the like. It is also possible to display the moving speed at. In the example of Fig. 10, the moving speed at each position of the waiting vehicle train entering the parking lot is obtained, and for example, "very slow", "slowly flowing", "relatively flowing" depending on the moving speed at each position. The congestion level is expressed in three stages, and sections of each congestion level are classified and displayed by color or pattern. Similarly, it is possible to calculate and display the travel time per unit section at each position. Thus, by classifying and displaying the standby vehicle trains according to the moving speed, the user can intuitively recognize the congestion state of the queue.

As described above, according to the present embodiment, the parking lot information including information such as the interval of the waiting vehicle train and the last position when entering the POI such as a parking lot is generated, which is useful for the user and Can provide useful POI related information. At this time, it is possible to provide information related to the entry route so that the parking lot can be entered smoothly regardless of whether there is a waiting vehicle. Based on this parking lot information, the entry route to the parking lot is identified via the road section where the waiting vehicle train is formed, and if the waiting vehicle train is formed by proceeding along that route, it reaches the end. It is possible to On the information side, if there is a waiting vehicle line based on information such as the entrance to the parking lot and the waiting status for entry, the entrance to the parking lot should be entered so that it can reach the tail smoothly.
