1. A method of controlling a mobile information terminal including a positioning sensor, the method comprising:
- creating a travel speed model indicating a time variation of an estimated value of a travel speed when the mobile information terminal moves from a current location to a destination location, based on a distance to the destination location, information on a speed of a mode of travel to the destination location, and information on stopping before arriving at the destination location; and
calculating a next measurement time to cause the positioning sensor to perform positioning based on the travel speed model.
