Real-time traffic condition measurement
First Claim
1. A computer program product embodied in a non-transitory 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 cell phone tower triangulation to locate a 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 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 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.

Abstract
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.
