Get and display web pages based on. For example, when the two-dimensional code printed on the parking ticket is photographed by the camera 415, the control unit 411 causes the touch panel 414 to display a transmission request web page based on the URL obtained from the two-dimensional code. . The information obtained by decoding the two-dimensional code includes an identification ID for identifying the parking lot, and when the transmission request web page is displayed, the average time required for exiting any parking lot. It is specified whether an information transmission request is made. In the transmission request web page, the exit of the specified parking lot is displayed as an option, and the user can select an exit when leaving the parking lot. Then, when the user selects an exit scheduled to leave from the transmission request web page and presses the transmission request button on the transmission request web page, the control unit 411 outputs a parking lot ID that identifies the identified parking lot. A transmission request for the average leaving time information is transmitted to the server SV together with the exit ID for identifying the exit of the server.

[4. Operation example of delivery management system S]
Next, an operation example of the retrieval management system S will be described with reference to the flowchart of FIG.

  When detecting that the navigation device NV is powered on and started, the control unit 211 of the navigation device NV determines whether or not the current position of the vehicle is in the parking lot (step S11A). At this time, when the control unit 211 determines that the current position of the host vehicle is not in the parking lot (step S11A: NO), the process illustrated in the flowchart ends. On the other hand, when the control unit 211 determines that the current position of the own vehicle is in the parking lot (step S11A: YES), the control unit 211 waits until it detects that the own vehicle starts moving (step S12A: NO). For example, the control unit 211 determines that the own vehicle has started moving when the current speed of the vehicle is no longer “0 km / h”. If the control unit 211 determines that the vehicle has started moving (step S12A: YES), the control unit 211 starts measuring the required exit time (step S13A).

  Next, the control unit 211 waits until the current position of the own vehicle is out of the parking lot (step S14A: NO), and when it is determined that the current position of the own vehicle is outside the parking lot (step S14A: YES), The measurement of the required leaving time is ended (step S15A). Next, the control unit 211 outputs a parking lot ID for identifying the exiting parking lot, an exit ID for identifying the exit that exits, information indicating the current time managed in the navigation device NV, and an exit required time indicating the measured exit required time. The information is transmitted to the server device SV (step S16A), and the processing shown in the flowchart ends.

  On the other hand, when determining that the control unit 311 of the server device SV has received the parking lot ID, the exit ID, the information indicating the current time, and the required leaving time information from the navigation device NV (step S11B: YES), the control unit 311 retrieves the information. It is registered in the required time DB (see FIG. 3A) (step S12B). On the other hand, if the control unit 311 determines that the parking lot ID, the exit ID, the information indicating the current time, and the required leaving time information have not been received from the navigation device NV (step S11B: NO), the process proceeds to step S13B. .

  Next, the control unit 311 determines whether or not the current time managed in the server device SV is an average retrieval required time calculation timing (step S13B). For example, as the average retrieval required time calculation timing, the time after “minute” is “00:00 second”, “05:00 second”, “10:00 second”, “15:00 second”, “20:00 second” ”,“ 25:00 ”,“ 30:00 ”,“ 35:00 ”,“ 40:00 ”,“ 45:00 ”,“ 50:00 ”,“ 55:00 ” The time indicated by is set. If the control unit 311 determines that it is the average retrieval time calculation timing (step S13B: YES), the control unit 311 refers to the retrieval time DB and includes the retrieval time in the latest 5 minutes for each exit ID. The average retrieval time is calculated based on the retrieval time, which is data, and registered in the average retrieval time DB (see FIG. 3B) (step S14B). On the other hand, when the control unit 311 determines that it is not the timing for calculating the average retrieval time (step S13B: NO), the control unit 311 shifts to the process of step S15B.

  On the other hand, the control unit 411 of the mobile terminal device T, when the user selects an exit scheduled to leave on the transmission request web page and presses the transmission request button, the parking lot ID identifying the parking lot scheduled to leave. (In this embodiment, the transmission request is included in the information obtained by decoding the two-dimensional code printed on the parking ticket) and a request for transmitting average exit time information together with the exit ID for identifying the exit at the time of exit from the server SV. It transmits (step S11C).

  When the control unit 311 of the server SV receives the transmission request for the average leaving time information from the mobile terminal device T (step S15B: YES), the parking lot ID received together with the transmission request is referred to the average leaving time DB. And the latest average required leaving time registered in association with the exit ID, and transmits the obtained average required leaving time indicating the average required leaving time to the portable terminal device T that has transmitted the transmission request. (Step S16B), and the process proceeds to step S11B. On the other hand, when the control unit 311 determines that the transmission request of the average leaving time information has not been received from the mobile terminal device T (step S15B: NO), the process proceeds to step S11B.

  On the other hand, after the processing in step S11C, the control unit 411 of the mobile terminal device T waits until receiving the average retrieval time information from the server device SV (step S12C: NO). (Step S12C: YES), the average leaving time indicated by the average leaving time information is displayed on the touch panel 414 (Step S13C), and the processing shown in the flowchart ends.

  As described above, the server device SV (an example of the “server device”) according to the present embodiment includes the control unit 311 (an example of the “acquisition unit”, the “accumulation unit”, the “detection unit”, and the “notification control unit”). ) Indicates the congestion at the exit of a parking lot (an example of “stationary”) that parks (an example of “stationary”) a vehicle (an example of “moving object”) (an example of “congestion information”). From the navigation device NV (an example of a “terminal device”) that moves together with the vehicle that has exited the exit, and stores the acquired exit required time information in the exit required time DB of the storage unit 312 (an example of a “storage unit”). Based on the accumulated retrieval time information, the average retrieval time information (an example of “hourly congestion information”) is detected every 5 minutes (an example of “every predetermined time”) and detected first. The latest average retrieval time information obtained from the portable terminal device T To send.

  Therefore, according to the server device SV according to the present embodiment, since the latest average leaving time information is transmitted to the mobile terminal device T, the user can grasp the actual traffic congestion situation near the exit of the parking lot. it can. Then, when the exit is congested, the user can spend time in a commercial facility or an entertainment facility, and can avoid the stress of the congestion.

  Further, the control unit 311 of the server device SV according to the present embodiment further obtains, from the navigation device NV, an exit ID (an example of “exit identification information”) for identifying an exit from which the vehicle exited, and the acquired exit ID The required exit time information is stored in the exit required time DB in association with the above, and the average exit required time information is detected for each exit based on the exit ID. Further, the control unit 311 further receives an exit ID indicating the exit of the average exit required time information requested to be transmitted from the mobile terminal device T, and obtains the latest average exit required time information corresponding to the exit identified by the received exit ID. Send As a result, the latest average exit required time information corresponding to the exit identified by the exit ID received from the mobile terminal device T is transmitted to the mobile terminal device T, and the vicinity of the exit designated by the user to the user is thus obtained. An actual traffic jam situation can be notified.

[5. Modification]
Next, a modification of the above embodiment will be described. Note that the modifications described below can be appropriately combined.

[5.1. Modification 1]
In the above-described embodiment, the average time required for leaving the warehouse is only displayed on the touch panel 414 of the mobile terminal device T. However, when the displayed average time required for leaving is long, and the user does not want to take the time to leave the warehouse. There is. Therefore, the user sets the time allowable as the required leaving time as the allowable condition, and the control unit 311 of the server device SV notifies the portable terminal device T when the average required shipping time satisfies the allowable condition. It may be notified.

  Specifically, an input area for inputting an allowable time is provided in a screen (see step S13C in FIG. 7) for displaying the average time required for leaving the warehouse, the allowable time is input in the input area, and the transmission button is pressed. In this case, the control unit 411 of the portable terminal device T transmits the allowable condition information including the allowable time to the server device SV. On the other hand, upon receiving the permissible condition information, the control unit 311 of the server SV satisfies the permissible condition indicated by the permissible condition information every time the average required retrieval time is calculated (see step S14B in FIG. 7). It is determined whether or not the notification has been performed, and when it is determined that the permissible condition has been satisfied, the notification information is transmitted to the portable terminal device T. Then, upon receiving the notification information, the control unit 411 of the mobile terminal device T causes the touch panel 414 to display a message indicating that the average retrieval time has satisfied the allowable condition. For example, if the user inputs "10 minutes" in the input area and presses the send button, if the average retrieval time is within "10 minutes", "the average retrieval time is less than 10 minutes" Is displayed on the touch panel 414. Thereby, the user can recognize that the average retrieval time has satisfied the allowable condition. Further, by notifying when it is determined that the permissible condition is satisfied, it is possible to save the trouble of the user having to check the average time required for leaving the warehouse every time even though the permissible condition is not satisfied. Can also.

[5.2. Modification 2]
In the above embodiment, the leaving required time information is used as the congestion information indicating the congestion at the exit. Alternatively, average speed information indicating the average speed of the vehicle at the time of leaving the vehicle may be used.

  In addition, since the required parking time varies depending on the distance from the parking position in the parking lot to the exit (particularly, in a large-scale parking lot, the distance varies greatly), and indicates the longest leaving time and the minimum leaving time every 5 minutes. The information may be transmitted to the mobile terminal device T together with the average retrieval time information and displayed on the touch panel 414 to notify the user. Further, when the control unit 211 of the navigation device NV transmits the required leaving time information, the control unit 211 transmits parking position information indicating the parking position to the server device SV, and the server device SV transmits the required leaving time DB. In the case where the average leaving time is calculated, the average leaving time may be calculated in consideration of the parking position indicated by the parking position information. For example, the control unit 311 of the server SV divides the parking lot into a plurality of areas, and calculates an average time required for exiting from each area. Then, as receiving position information indicating the position where the user's vehicle is parked from the mobile terminal device T, the control unit 311 transmits the average leaving required time information calculated for an area including the position information. It shall be. Thereby, it is possible for the user to grasp the average leaving required time information excluding the influence of the variation of the leaving required time based on the distance from the parking position in the parking lot to the exit.

[5.3. Modification 3]
In the above-described embodiment, the required exit time is the time required for the vehicle to start moving in the parking lot and exit outside the parking lot. However, the start of measurement of the exit required time is determined by turning on the power to the navigation device NV. It may be empty. Alternatively, the measurement of the time required for leaving the warehouse may be completed when the vehicle passes through a toll gate, exits on a public road, or exits from the toll gate, passes through a site such as a commercial facility, and goes out of the site.

[5.4. Modification 4]
In the above embodiment, when the transmission request of the average retrieval time information is received from the portable terminal device T, the control unit 311 transmits the latest average retrieval time information to the portable terminal device T, and the portable terminal serving as the notification means. The device T notifies the user of the congestion near the exit by displaying the average time required for leaving the warehouse, but instead notifies the user of the congestion using an electronic bulletin board installed in a commercial facility or the like. It is good also as making it do. For example, when the control unit 311 calculates the average exit required time for each exit in the process of step S14B in FIG. 7, the control unit 311 displays display information for displaying the latest average exit required time for each exit on the electronic bulletin board. Will be sent to Then, the electronic bulletin board that has received the display information displays the average required leaving time for each exit as shown in FIG. Thus, the user can grasp at a glance the congestion near each exit from the display on the electronic bulletin board 500. Further, on the electronic bulletin board, the average time required for leaving the warehouse may be represented by a color. For example, when the average time required for retrieval is 20 minutes or more, red is displayed. When the average time required for retrieval is 5 minutes or more and less than 20 minutes, yellow is displayed. In some cases, the average retrieval time is expressed in color, such as displaying green. This allows the user to intuitively grasp the congestion at each exit. Here, the case where the notification means is an electronic bulletin board installed in a commercial facility or the like has been described, but the notification means may be a speaker installed in a commercial facility or the like. In this case, the control unit 311 transmits to the speaker audio information for outputting the average required leaving time for each exit in audio. Then, the speaker having received the audio information outputs a message representing the average required leaving time for each exit by voice. Thereby, the user can grasp the congestion near the exit from the message output from the speaker.
