  • Patent number: 9316504
    Abstract: Disclosed is navigation technology for providing guidance for HOV lanes in a more readily understandable manner. A navigation device is provided with: a storage unit adapted to store lane information including the set-up of lanes which can be used when a predetermined condition is fulfilled (hereafter referred to as conditional lanes); a route guidance unit adapted to provide guidance for a recommended route to a destination; and a guidance unit adapted to provide guidance for entrances and exits for conditional lanes. If travelling along a conditional lane makes it impossible to continue without deviating from the recommended route, the guidance unit provides guidance that the conditional lane should not be entered from an entrance to the conditional lane or inhibits guidance on the presence of an entrance to the conditional lane.

  • Publication number: 20130035858
    Abstract: Disclosed is navigation technology for providing guidance for HOV lanes in a more readily understandable manner. A navigation device is provided with: a storage unit adapted to store, for each predetermined segment of road, lane information including whether or not it is possible to enter or exit lanes which can be used when a predetermined condition is fulfilled (hereafter referred to as conditional lanes); a route search unit adapted to search for a recommended route to a destination; and a lane guidance unit adapted to provide entry/exit guidance in a road segment where a conditional lane can be entered or exited. If a segment where a conditional lane can be exited and a segment where the conditional lane can be entered, which is before the segment which can be exited, are on the recommended route, the lane guidance unit provides entry guidance in the segment where the lane can be entered.
