Abstract
A navigation system for automotive vehicles generates navigation routes between an initial location and a desired destination using a route criteria including a statistical risk index, such as a CAP crime index score. A user of the navigation system can customize their own desired risk threshold to be used in optimizing the navigation route. A particular route segment with a risk index above a risk threshold can be eliminated from potential routes except when the route segment contains the destination or is a freeway segment. In another embodiment, the weight or cost associated with including a route segment in a navigation route is adjusted according to its statistical risk index.
