Abstract (en)
[origin: WO9914701A1] A navigation system (20) permits the user to designate certain roads or area to avoid when planning a route. The navigation system generally includes a database (28) of road segments and a cost associated with the road segments, such as estimated time or travel across that road segment and estimated length of travel across that road segment. The navigation system (20) determines a route from a selected beginning point to a desired destination by evaluating the cost of the road segments to be traveled in several potential routes and recommends the potential route having the lowest total cost. The user can selectively modify the cost of selected road segments to indicate a preference or avoidance of such roads. By increasing the cost of a road segment, the navigation system (20) is less likely to recommend a potential route which includes that road segment. Similarly, by decreasing the cost of a selected road segment, the navigation system (20) is more likely to recommend a potential route which includes that road segment.
