Abstract
A navigation system includes a positions network having a plurality of nodes, each corresponding to a segment in a road segments network. A branch is propagated from each node in the positions network based upon a dead reckon path of position vectors. Each of the branches in the positions network represents a potential current position of the vehicle. The branches in the positions network are compared to the segment in the segments network to determine a current position of the vehicle.
