Abstract
A method for route calculation using real time traffic conditions is disclosed. A transmission that includes weightings indicative of traffic conditions on roads is received. Then, a solution route is calculated by forming a list of road segments. The list is formed by expanding a search tree comprised of gates. Each gate represents a physical location on a road segment and an accessible direction relative thereto. Each gate to which a weighting applies is incremented by an amount indicated in the transmission. The solution route is determined by expanding the search tree, which includes determining and evaluating successor gates.
