CELLULAR-BASED LIVE TRAFFIC SERVICE
First Claim
Patent Images
1. A method comprising:
- determining a plurality of location regions, each location region of the plurality of location regions being indicative of a location of a cellular device;
determining at least one route that intersects all the location regions of the plurality of regions;
determining, for each of the at least one route, a shortest distance between a centroid of each location region of the plurality of regions and the at least one route; and
aggregating the determined shortest distances to determine an estimated location of the cellular device.

Abstract
A cellular-based live traffic service that does not require pre-deployment of infrastructure or GPS-enabled devices uses signals provided by cellular devices to determine course resolution localization and tracking information of the cellular devices. Specialized statistical analysis is performed on the course resolution data to infer the fine resolution positions of the cellular devices. In an example embodiment, the localization and tracking information is provided on a map, or the like, to show relative position and/or trajectory of cellular devices.
