Abstract:
A method for modeling and processing vehicular traffic data and information, comprising the steps of:(a) transforming a spatial representation of a road network associated with the vehicular traffic data and information into a network of spatially interdependent and interrelated oriented road sections, for forming an oriented road section network; (b) acquiring a variety of the vehicular traffic data and information associated with said oriented road section network, from a variety of sources; (c) prioritizing, filtering, and controlling, the vehicular traffic data and information acquired from each of said variety of sources; (d) calculating a mean normalized travel time (NTT) value from a plurality of normalized travel time (NTT) values of each of a plurality of vehicles, normalized with respect to a pre-determined distance, for each said oriented road section of said oriented road section network using said prioritized, filtered, and controlled, vehicular traffic data and information associated with each said source, for forming a partial current vehicular traffic situation picture associated with each said source; and (e) fusing said partial current traffic situation picture associated with each said source, for generating a single complete current vehicular traffic situation picture associated with entire said oriented road section network and with said road network.
