The device may include a computer-readable memory element on which is stored a plurality of templates comprising historical speed values for a quantity of time segments and a map database including data for a plurality of road segments associated with template codes identifying one or more of the templates. The device may also include a processing device for accessing the map database to determine a historical speed value for one or more selected road segments.
