摘要：The present invention is a method and an apparatus for estimating real-timetravel times or traffic loads (e.g., traffic flows or densities) over a transportation network

based on limited real-time data. In one embodiment, a method for estimating a traveltime over a transportation network comprising at least a first link and a second linkincludes receiving a data feed associated with a real-time traffic flow over the first link,estimating a first travel time over the first link based at least in part on the data feed, andestimating a second travel time over the second link, also based at least in part on thedata feed. The method assumes that a real-time data feed is not available for the secondlink, and thus estimates the traffic flow over the second link based on the known trafficflow over the first link and other known data, such as historical traffic patterns andphysical parameters of the transportation network.
