  • the speed at which the moving body passes through the connection N1 the time required for the moving body V to move through the first section X can be predicted with high accuracy.
  • the distance of the first section X is short but the time required for the moving body V to move through the first section X is large due to congestion, it is possible to output exit route information, making it possible to provide effective route guidance according to the situation.
  • the output control unit 20 does not output the exit route information by voice in the first section X where at least one of the distance of the first section X and the time required for the moving body V to move through the first section X does not satisfy the specified criterion. For example, in a case where both the distance of the first section X and the time required for the moving body V to move through the first section X are calculated as objects to be compared with the specified criterion, the output control unit 20 does not output the exit route information by voice in the first section X where both the distance of the first section X and the time required for the moving body V to move through the first section X do not satisfy the specified criterion.

  • the output control unit 20 repeatedly outputs at least one of the omission information and the sound information in the second section Y, the first section X2, the first section X3, the first section X4, the first section X5, and the first section X6.
  • the number of divided sounds may indicate the number of branch routes that the exit route D100 is, counting from the current location of the moving body V (for example, in the above example, the "beep beep beep" sound information indicates that the exit route D100 is the fourth branch route D, counting from the current location of the moving body V).
  • the output control unit 20 may also change the omitted information according to the number of branch roads D that the exit road D100 is, counting from the current location of the mobile body V, such as "6" for the second section Y, "5" for the first section X2, “4" for the first section X3, “3” for the first section X4, "2" for the first section X5, and "1” for the first section X6.
  • the omission information and sound information can shorten the sound output time compared to the exit route information. This makes it possible to effectively inform the driver which branch route D the exit route D100 is, without confusing the driver, even if there are a relatively large number of first sections X in which at least one of the distance of the first section X and the time required for the moving body V to move through the first section X does not meet a predetermined standard.
