PEDESTRIAN TRAFFIC MONITORING AND ANALYSIS

摘要

Numerous mobile devices report their respective locations to a server which collects the location reports to provide real-time pedestrian traffic information, e.g., as a map that shows locations of individual mobile devices. Distribution of mobile devices in a geographic area more closely represents overall population locations and densities. Each device is identified by a digital fingerprint, formed from a number of system and device configuration parameters. Each mobile device is configured to periodically report its location, e.g., at a predetermined time interval and/or whenever the mobile device determines its location for another reason. A known location of a wireless network access point to which a mobile device is connected can serve as an estimated location of the mobile device.

主权项

1. A computer system comprising:
at least one processor; a computer readable medium that is operatively coupled to the processor; network access circuitry that is operatively coupled to the processor; and location monitoring and assessment logic (i) that executes at least in part in the processor from the computer readable medium and (ii) that, when executed, causes the processor to report traffic information regarding a population of people by at least: receiving a request for the traffic information from a remotely located client device, wherein the request specifies one or more attributes of the traffic information; in response to the request, determining respective locations of two or more computing devices wherein determining includes, for each of the computing devices:
sending an authentication challenge to the computing device;receiving location data and authentication data from the computing device wherein the authentication data is responsive to the authentication challenge;comparing the authentication data to predetermined authentication data associated with the computing device; andaccepting a location identified by the location data as the respective location of the computing device upon a condition in which the authentication data matches the predetermined authentication data; preparing the traffic information from the attributes and the locations; and sending the traffic information to the client device.
