Navigation system, method and device with detour algorithm
First Claim
1. A navigation system with route calculation capabilities, comprising:
- a server having a processor and a memory, the memory having cartographic data and a route stored therein to navigate from a beginning position to a desired destination, the cartographic data including data indicative of thoroughfares of a plurality of types, the route including a number of decision points; and
wherein the processor operates on a route calculation algorithm and user-selectable preference levels, including high, medium, and low preference levels relating to a portion of a particular thoroughfare in a route in order to calculate a new route.

Abstract
Systems, devices and methods are provided for an improved navigational route planning device which provides more understandable, accurate and timely route calculation capabilities. The navigational aid device with route calculation capabilities includes a processor connected to a memory. The memory includes cartographic data and a desired destination, the cartographic data including data indicative of thoroughfares of a plurality of types. A display is connected to the processor and is capable of displaying the cartographic data. The device is adapted to process the device=s location and travel along a planned route. And, the device is adapted to dynamically calculate a new route to the desired destination with a preference for avoiding a particular portion of a thoroughfare or one or more different thoroughfares in a previous route.
