| 摘要 |
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.
