发明名称 REAL-TIME TRAFFIC CONDITION MEASUREMENT
摘要 In embodiments of the present invention improved capabilities are described for identifying a first location, at time one, of a plurality of automobiles using cell phone tower triangulation to locate a cell phone within each of the plurality of automobiles, identifying a second location, at time two, for each of the plurality of automobiles using cell phone tower triangulation to locate the cell phone within each of the plurality of automobiles, calculating a vehicle speed for each of the plurality of automobiles using the first and second locations already identified, and creating a traffic condition measure for a route in proximity to the first and second locations. The computer program product may repeat this process in real-time to calculate a real-time traffic condition measure that may be a traffic density measure the computer program product may use to predict a travel time.
