Method and system for modeling and processing vehicular traffic data and information and applying thereof

摘要

A method and system for modeling and processing vehicular traffic data and information, comprising: (a) transforming a spatial representation of a road network 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 the oriented road section network, from a variety of sources; (c) prioritizing, filtering, and controlling, the vehicular traffic data and information acquired from each of the variety of sources; (d) calculating a mean normalized travel time (NTT) value for each oriented road section of said oriented road section network using the prioritized, filtered, and controlled, vehicular traffic data and information associated with each source, for forming a partial current vehicular traffic situation picture associated with each source; (e) fusing the partial current traffic situation picture associated with each source, for generating a single complete current vehicular traffic situation picture associated with entire oriented road section network; (f) predicting a future complete vehicular traffic situation picture associated with the entire oriented road section network; and (g) using the current vehicular traffic situation picture and the future vehicular traffic situation picture for providing a variety of vehicular traffic related service applications to end users.

主权项

1. A method for modeling and processing vehicular traffic data, comprising the steps of:
generating a representation of a road network associated with the vehicular traffic data, the road network comprising a plurality of road sections; and acquiring vehicular traffic data associated with said road network from a plurality of mobile sensors in communication with a wireless telecommunication network, wherein acquiring vehicular traffic data comprises selecting a sample comprising vehicle-carried mobile sensors from the plurality of mobile sensors and tracking locations of said vehicle-carried mobile sensors of said sample over the road network, the method further including a procedure for protecting privacy of individuals associated with said vehicle-carried mobile sensors, comprising tracking locations of said vehicle-carried mobile sensors of said sample without identifying tracked vehicles by using phone numbers, and keeping identities of the vehicle-carried mobile sensors within the location of the wireless telecommunications network so that privacy of the individuals associated with said vehicle-carried mobile sensors are protected.
