  • Method and apparatus for route calculation involving freeway junction
    Patent number: 9829328
    Abstract: A method and apparatus of calculating a route involving a freeway junction determines an undesired freeway junction that can pose a driving difficulty, and performs route recalculation that avoids the undesired freeway junction. A distance from a freeway entry to a freeway junction, or a number of freeway entries up to the freeway junction are used to determine the undesired freeway junction. A distance from the freeway junction to a freeway exit is also used to determine the undesired freeway junction. An intermediate point is set to recalculate a route that does not involve the freeway junction to create an overall route.
