Real-time traffic condition measurement using GPS data
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 a first set of GPS coordinates that are associated with a cell phone to locate 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 a second set of GPS coordinates that are associated with the cell phone 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;
receiving a user request from a user'"'"'s cell phone for traffic condition information associated with the route;
wherein the user'"'"'s request is automatically generated from the cell phone upon detection of the cell phone by a cell tower in proximity to the first and second locations; and
presenting the real-time traffic condition measure to the display of the user'"'"'s cell phone.

Abstract
In embodiments of the present invention, a computer program may use GPS coordinates associated with cell phones located within multiple cars to measure real time traffic conditions. These traffic conditions may be measured based at least in part on using parameters including, but not limited to, a time of day, a day of the week, a weather condition, a road condition, or some other parameter relating to traffic conditions. The traffic conditions may be used to calculate a vehicle speed between two locations and predict related travel time. The real-time traffic condition information may be manually accessed by a user from their cell phone or automatically presented to a user'"'"'s cell phone when the cell phone enters a specific geographic location or region.
