Abstract: Initial navigation directions are generated to guide a vehicle along an initial route between an origin and a destination. When the vehicle is a certain location disposed along the initial route, an alternate route to the destination is determined, such that the alternate route and the initial route diverge at a point of divergence between the current location of the vehicle and the destination. Boundaries of an announcement window within which the alternate route can be suggested are determined in view of a current speed of the vehicle. When the point of divergence is within the announcement window, generating, by the one or more processors, an interactive prompt to suggest that the alternate route be selected, such that the interactive prompt is not generated when the point of divergence is outside the announcement window.
