Abstract
A method and system for calculating an energy efficient route is disclosed. A route calculation application calculates one or more routes from an origin to a destination. For each of the routes, the route calculation application uses impedance factor data associated with each segment in the route. The impedance factor is calculated using probe data when the probe data is available for a road segment. When probe data is unavailable, the impedance factor is calculated using machine learning techniques that analyze the results of the impedance factor classifications for road segments having probe data.
