A method of calculating a navigation route based on an estimated energy consumption value that assigns a distance weight coefficient for each of the plurality of potential routes that corresponds to an estimated distance energy consumption value. The method also determines a cumulative interference weight coefficient for each of the plurality of potential routes corresponding to an estimated interference energy consumption value based on traversing at least one interference event in the potential route. Each cumulative interference weight coefficient may include a fixed event interference weight coefficient, a probable event interference weight coefficient, and a scheduled event interference weight coefficient. The system then determines total route energy consumption weight coefficients for each of the plurality of potential routes by adding the distance and cumulative interference weight coefficients, and selects a route from the plurality of potential routes based on a lowest total route energy consumption weight coefficient.
