发明名称 Cellular-based live traffic service
摘要 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.

主权项 1. A method comprising: determining a plurality of geographic regions, each geographic region of the plurality of geographic regions being indicative of a location of a device; determining social information pertaining to a user of the device; based at least on the determined social information, determining at least one route that intersects all the geographic regions of the plurality of geographic regions; determining, for each of the at least one route, a shortest distance between a centroid of each geographic region of the plurality of geographic regions and the at least one route; aggregating the determined shortest distances; and determining traffic information based on the aggregated shortest distances.
