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 segment cost data associated with each segment in the route. The segment cost is calculated by adjusting an energy consumption value by subtracting a bias term for each segment with known slope data. The bias term causes segment costs associated with segments having a slope that can be traveled with typical efficiency, a zero slope, and an unknown slope to be substantially the same. The bias term also causes the segment cost associated with a segment with a slope that can be traveled efficiently to be less than the segment cost associated with a segment with unknown slope, and the segment cost associated with a segment with a slope that causes inefficient travel to be greater than the segment cost associated with a segment with unknown slope."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for calculating an energy efficient route","description":"A method and system for calculating an energy efficient route is disclosed.
