Description

  The present invention relates to a navigation apparatus having a function of guiding a route to a destination, and more particularly, to usage guidance when a resting facility is used on a toll road such as a metropolitan expressway.

  ETC (registered trademark: Electronic Toll Collection SYSTEM), DSRC (Dedicated Short Range Communication), and the like have been put to practical use as data communication methods between roadside devices and vehicle-mounted devices. ETC is a typical automatic toll collection system that can collect tolls automatically without stopping at a toll gate on a toll road. When using ETC, it is necessary to mount an in-vehicle ETC device that can wirelessly communicate with a roadside ETC device.

  ETC is typically used in interchanges (entrances) that enter highways from general roads, and interchanges (exit) that exit from highways to general roads. As a further development of ETC, An unmanned service that installs an ETC gate in a parking area or a service area and enables access through the gate is also widespread. For example, Patent Document 1 discloses a navigation device related to unattended smart interchange using ETC. Patent Document 2 discloses a navigation device that can set an appropriate getting-on / off interchange corresponding to a departure place and a destination.

  Currently, on toll roads such as the Metropolitan Expressway, the usage fee is uniform regardless of the usage distance, and a system is adopted in which the fee is collected again once getting off the toll road and then entering the toll road. However, on the Metropolitan Expressway, there are not enough rest facilities such as toilets. , You are forced to get off the Metropolitan Expressway and get back on the Metropolitan Expressway at the previous entrance.

  In order to eliminate such inconvenience, a service called a smart parking area (hereinafter abbreviated as “smart PA”) is currently being studied on the Metropolitan Expressway. Smart PA is a system that provides services such as toilet breaks in sections where parking areas are not installed in cooperation with businesses near the Metropolitan Expressway. As an application condition of smart PA, it is necessary to get off the designated exit of the Metropolitan Expressway, use the designated facility, and reenter the Metropolitan Expressway from the designated entrance within a certain time (for example, 2 hours). If this condition is satisfied, the use of the smart PA is regarded as a continuous use of the Metropolitan Expressway and the fee is not collected again. Therefore, the navigation device is required to have a function of appropriately guiding information related to the smart PA.
