Abstract:
1. A travel guidance system comprising: a navigation-route setting unit that sets a navigation route along which a movable body is guided and a guidance junction on the navigation route; a junction acquiring unit that acquires a position of a preceding junction that is located closer to a departure place of the navigation route than the guidance junction; a guidance setting unit that sets guidance on the guidance junction; and a junction guiding unit that provides guidance on the guidance junction on the basis of the guidance set by the guidance setting unit, wherein the guidance setting unit sets the guidance such that the guidance includes a first phrase for specifying a positional relationship between the movable body and the preceding junction, a second phrase for specifying a positional relationship between the movable body and the guidance junction after the movable body has passed through the preceding junction, and a third phrase indicating a positional relationship between the moving body and the guidance junction before passing through the preceding junction, wherein the guidance setting unit determines whether the third phrase is suitable as guidance by determining if the third phrase can be started and finished within a predetermined timing, sets the third phrase as the guidance set, and if the third phrase is not suitable, the guidance setting sets the first phrase or the second phrase as the guidance set.
