IDENTIFYING COST EFFECTIVE ROUTES USING VEHICLE FUEL ECONOMY VALUES THAT ARE SPECIFIC TO THE ROADWAY TYPE

摘要

A method includes identifying a starting location and a destination for traveling in a vehicle and identifying multiple available routes. Each available route includes roadway segments that each have a roadway type selected from multiple roadway types that reflect a unique set of roadway conditions. The method obtains a price of fuel available to the vehicle, obtains a fuel economy value for the vehicle on each roadway type, and calculates a cost of driving each of a plurality of available routes. The cost of driving each available route is the sum of the cost of driving each segment of the route, wherein the cost of driving each roadway segment is the mathematical product of a length of the roadway segment and the available fuel price divided by the fuel economy for the vehicle on the roadway type for the roadway segment. The lowest cost route is then identified.
