Anonymous Wireless Address Matching for Traffic Information
First Claim
1. A system for monitoring traffic on a roadway in real-time, comprising:
- a plurality of reader devices, wherein the reader devices are capable of asynchronously capturing a unique network identifier of a device in a vehicle when the device is disposed in reader range of the reader devices, and wherein the reader devices time stamp each captured unique network identifier, and further wherein a time stamped unique network identifier is forwarded to a host module; and
wherein the host module receives the time stamped unique network identifier, and wherein the host module determines travel information from the time stamped unique network identifier by comparing the time stamped unique network identifier for a particular vehicle to other time stamped unique network identifiers captured for the particular vehicle.

Abstract
Methods and systems include determining travel information from vehicles. In one embodiment, a system monitors traffic on a roadway in real-time. The system includes a plurality of reader devices. The reader devices are capable of asynchronously capturing a unique network identifier of a device in a vehicle when the device is disposed in reader range of the reader devices. The reader device time stamps each captured unique network identifier. The time stamped unique network identifier is forwarded to a host module. The host module receives the time stamped unique network identifier. In addition, the host module determines travel information from the time stamped unique network identifier by comparing the time stamped unique network identifier for a particular vehicle to other time stamped unique network identifiers captured for the particular vehicle.
