The disclosure generally relates to techniques that may reduce power consumption and improve user experience when using a personal navigation device or other mobile device to navigate along familiar routes or road segments. In particular, in response to a current position associated with the device corresponding to a familiar road segment (e.g., based on an index indicating how often the road segment was previously traversed), voice assistance and a display may be disabled and/or a frequency at which a receiver acquires signals to determine the current position may be reduced. Furthermore, a navigation application executing on the device may be automatically exited if the familiar road segment further includes a route destination. In other use cases, road segment familiarity and travel histories may be used in route planning, managing incoming calls or messages, and media playback, among other things.
