1. A method of location refinement, comprising:
- aggregating global positioning system (GPS) data, received from each of multiple devices that are proximately located relative to at least one other of the multiple devices, over a period of time;
estimating a location for each of the multiple devices at intervals during the period of time based on, at least, the aggregated GPS data; and
determining a current location for each of the devices based on a trend of the estimated locations for each of the multiple devices over the period of time.

Abstract
In some examples, a system to produce refined location information for multiple vehicles may aggregate GPS coordinates collected from each of multiple devices over a period of time, estimate a location for each of the multiple devices at intervals during the period of time, track the locations for each of the multiple devices over the period of time, and determine a current location, on a road, of the vehicle corresponding to each of the devices based on a detected trend of the tracked locations for each of the multiple devices over the period of time.

9. A system to produce refined location information for multiple vehicles, comprising:
-
multiple devices, disposed with respectively corresponding vehicles, each configured to record GPS coordinates at multiple intervals over a period of time; and a server configured to; aggregate GPS coordinates collected from each of multiple devices over the period of time, estimate a location for each of the multiple devices at intervals during the period of time, track the locations for each of the multiple devices over the period of time, and determine a current location, on a road, of the vehicle corresponding to each of the devices based on a detected trend of the tracked locations for each of the multiple devices over the period of time. - View Dependent Claims (10, 11, 12, 13, 14, 19, 20)
