- the display processing unit 45 may display the detailed information 223, 333 of the restriction information when the cursor power on the screen is set on or around the restriction information displayed.
- Fig. 15 shows a display example when power is applied.
- Detailed information 545b is displayed because the cursor 552 is close to the regulation information 545.
- a parking lot that is open during the time of interest may be displayed.
- the in-vehicle navigation device 100 holds the location information and business hours information (parking lot information) for each parking lot in the storage device 3.
- the parking lot information may be stored in advance in the storage device 3 or the traffic information. It may be received from the information delivery server 200 and stored in the storage device 3.
- the display processing unit 45 extracts the parking lot information capability and displays the parking lot that is open during the time of interest. In this way, only the parking lot 547 that is open during the time of interest is displayed.
- FIG. 17 shows an example of a display screen when a request for changing the time period of interest is received during the display of traffic information.
- the display processing unit 45 displays an attention time zone designation screen 560.
- the specification is accepted from several time options.
- the closer the option time is to the current time the narrower the nicks (time intervals).
- the further away from the current time the larger the dent. For example, during the first hour from the current time, the choice of time every 5 minutes is displayed, within 1 to 3 hours, the choice of time every 15 minutes is displayed, and after that, every hour is displayed. Display time choices. From these options, designation of the time of interest is accepted.
- the display processing unit 45 sets the attention time zone, for example, within 30 minutes from the specified time.
- the configuration for displaying the traffic jam information and the restriction information in the attention time zone has been described.
- the present invention is not limited to this, and the traffic jam information is displayed for the attention time zone, and the restriction information is displayed. Information may be displayed at the current time.
- Fig. 18 shows the flow of processing when it works.
- the display processing unit 45 determines whether or not the difference between the current time and the time zone of interest (eg, the middle time of the time zone of interest) is less than a predetermined value (eg, 2 hours) (S510).
- a predetermined value eg, 2 hours
- the display processing unit 45 displays the restriction information at the current time and the traffic jam information at the time of interest on the map on the same screen. Even when the parking lot is displayed, the parking lot that is open during the time of interest is displayed (S512). sand That is, the processing of S420 to S468 shown in FIG. 13 is performed.
- the display processing unit 45 displays only the traffic jam information of the attention time zone. Do not display regulatory information WS514). That is, the processing of S420 and S456 is not performed among the processing of S420 to S468 shown in FIG.
- FIG. 19 is a display example when power is applied.
- Regulation information 645, 647, 646 is regulation information at the current time.
- the traffic jam information 541, 542, 543, 544 is traffic jam information in the attention time zone.
- the display processing unit 45 switches from displaying current traffic information that is current traffic information to displaying future traffic information (real-time predicted traffic information and statistical traffic information) from now on. It is possible to display only the traffic information and not the restriction information.
- the present invention can also be applied to a navigation device other than a vehicle-mounted navigation device.
