News editors obtained the following quote from the background information supplied by the inventors: "Route selection or optimization has applications in vehicle routing, printed wire circuit layout, chip design and layout, and biological activities. Trucking and other vehicle fleets, for instance, select vehicle routes to deliver goods to various destinations. Similarly, transportation companies route vehicles to pick up and drop off passengers. In addition to land-based vehicles, route selection can also be used for ship, airplane, and rail transport route scheduling.
"A typical route selection problem is to reduce or minimize the distance traveled or time spent traveling. Route selection problems might consider such factors as a number of turns in a given route, a number of intersections, speed limits, bridge crossings, and the like. Algorithms modeled using concepts from graph theory are often used to select routes."
As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "For purposes of summarizing the disclosure, certain aspects, advantages and novel features of the inventions have been described herein. It is to be understood that not necessarily all such advantages can be achieved in accordance with any particular embodiment of the inventions disclosed herein. Thus, the inventions disclosed herein can be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other advantages as can be taught or suggested herein.
"In accordance with some embodiments, a system for calculating routes for a plurality of vehicles in a vehicle fleet can include a street classification module comprising computer hardware and a route calculation module. The street classification module can receive custom data to classify streets of a network of streets in a geographic region for the purpose of efficiently determining how to route a plurality of vehicles in a vehicle fleet. Based at least in part on the received custom data, the street classification module can calculate custom routes on the network of streets in the geographic region between waypoint locations. Further, the street classification module can determine a classification for each street of the network of streets in the geographic region based at least in part on the calculated custom routes and store the determined classifications in a computer database. The classification can include an assigned score indicative of a hierarchical ranking of each street for calculating routes for the plurality of vehicles in the vehicle fleet on the network of streets in the geographic region. The route calculation module can calculate a first route on the network of streets in the geographic region for a first vehicle of the plurality of vehicles in the vehicle fleet using the stored classifications in the computer database to exclude a set of streets of the network of streets from evaluation for inclusion in the first route. In addition, the route calculation module can output the first route to a navigation device associated with the first vehicle for presentation to a driver of the first vehicle.
