1. A computer program product embodied in a computer readable medium that, when executing on one or more computers, performs the steps of:

  • Step One;

    identifying a first location, at time one, of a plurality of automobiles using triangulation to locate a cell phone within each of the plurality of automobiles, wherein the triangulation is based at least in part on data that is transmitted over a network that is utilized by the cell phone within each of the plurality of automobiles;

    indentifying a second location, at a time two, subsequent to time one, for each of the plurality of automobiles using triangulation to locate the cell phone within each of the plurality of automobiles, wherein the triangulation is based at least in part on data that is transmitted over a network that is utilized by the cell phone within each of the plurality of automobiles;

    calculating a vehicle speed for each of the plurality of automobiles using the first location at time one and the second location at time two;

    using the calculated vehicle speed for each of the plurality of automobiles to create a traffic condition measure for a route in proximity to the first and second locations; and

    Step Two;

    iteratively performing Step One, in real-time, at a time interval to calculate a real-time traffic condition measure.
