1. A computer-implemented method for calculating a green route, comprising:

  • obtaining an origin and a destination associated with a road network;

    calculating, by a processor, at least one route from the origin to the destination using geographic data representing roads in the road network, wherein the geographic data includes effective slope data that represents a fuel consumption impact of a slope of a road;

    calculating fuel consumption of the calculated routes using the effective slope data to identify a route that minimizes fuel consumption when traveling from the origin to the destination; and

    providing route guidance for traveling on the route that minimizes fuel consumption,wherein the geographic data includes actual slope data for road segments representing a road in the road network, and further comprising calculating a general fuel consumption value for a segment associated with an actual slope value,wherein the general fuel consumption value is calculated using the formula;


    GFC=Σ

    (distancen*LPK(slopen))/Σ

    (distancen)where distance is a length of the segment, slope is the actual slope value of the segment, and LPK is a lookup table value.
