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 system configured to model and process vehicular traffic data, comprising:
executable software configured to acquire vehicular traffic data associated with said road network from a sample of a plurality of mobile sensors in communication with a cellular wireless telecommunications network, the software stored in a computer readable medium and comprising instructions for selected said sample of said plurality of mobile sensors and for tracking locations of mobile sensors of said sample over the road network; wherein acquiring vehicular traffic data includes determining a normalized travel time (NTT) of the mobile sensors or a statistic indicating the travel speed, where the NTT refers to a travel time normalized with respect to a pre-determined distance; the computer readable medium further comprising instructions for representing a road network associated with the vehicular traffic data and information, the road network comprising a plurality of road sections; and the computer readable medium further comprising instructions for protecting the privacy of individuals associated with said mobile sensors of said sample by automatically deleting identities of said mobile sensors of said sample in response to incorporation of their derived velocities into processing associated with the plurality of sections.
