摘要:
A universal GPS traffic monitoring system that uses a plurality of GPS enabled mobile devices to transmit near real-time traffic direction and speed information to a server. The sever processes the information thereby reducing the computational load and power consumption of the mobile devices. The system uses a Traffic Pattern Recognition software program that recognizes only valid traffic data while filtering out unwanted traffic data. The system creates a Distributed Traffic Data Store database containing the average speeds for designated traffic monitoring points (TMPs) created for the region. A request for traffic data containing the boundary data and the zoom level is sent from the mobile device to the server. The server reviews the request and determines which specific Distributed Traffic Data Store database contains the information and then creates and sends a compressed file containing the traffic information relevant to the TMPs in the request to the mobile device.
