1. A method of location refinement, the method 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;
determining a current location for each of the multiple devices based on a trend of the estimated locations for a respective device, for each of the multiple devices over the period of time;
refining the determined current location of a vehicle that corresponds to a particular one of the multiple devices, relative to a road, by comparing the determined current location for each of the multiple devices.

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.

8. A system to produce refined location information for multiple vehicles, the system 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 the multiple devices over the period of time, estimate a location for each of the multiple devices at the multiple intervals during the period of time, track locations for each of the multiple devices over the period of time, determine a current location, on a road, of a vehicle corresponding to each of the multiple devices based on a detected trend of the tracked locations for a respective device, for each of the multiple devices over the period of time, wherein the determined current location includes an indication on which lane on the road, the vehicle, that corresponds to each of the multiple devices, is currently located and transmit the current location, at least relative to the road, to at least one of the multiple devices that corresponds to one of the multiple vehicles. - View Dependent Claims (9, 10, 11, 12, 13)
