Abstract
The present invention relates to a method for optimizing a route of a vehicle including planning an initial route using rules to estimate navigation system performance and to enhance accuracy of the navigation system and then utilizing a navigation performance prediction tool to evaluate possible success of the initial route. If the initial route is deemed a failure, estimated error may be recalculated based on the initial route and then the estimated error may be utilized to evaluate possible success of the initial route. If the initial route is deemed a failure, the rules may be used to designate at least one error correcting maneuver to be added to the initial route to reduce error and then the estimated error of the initial route including the error correcting maneuver may then be recalculated using the navigation prediction process. The possible success of the initial route including the error correcting maneuver may then be evaluated. This method may be repeated in whole or in part until a satisfactory route is obtained.
