Video data and GIS mapping for traffic monitoring, event detection and change prediction
First Claim
1. A distributed system for traffic monitoring and event detection, comprising:
- a plurality of video units located within viewing distance of at least one thoroughfare to be monitored, each video unit including a video camera, video frame processing logic, a processor and memory including computer program code configured to cause the video frame processing logic to process a video stream from at least one video camera while monitoring predefined categories of events at the at least one thoroughfare, to identify traffic monitoring events associated with the at least one thoroughfare, to analyze the traffic monitoring events, and to encode traffic meta data characterizing the analysis of the traffic monitoring events, each-video unit including a communications unit configured to transmit to a central controller the meta data characterizing analysis of the traffic monitoring events;
a central controller, including a processor and memory including computer program code configured to cause the central controller store at least one geographic map representing the at least one thoroughfare to be monitored, to cause the controller to correlate the traffic monitoring meta data received from the plurality of video units, and to cause the controller to form a composite representation of the at least one geographic map and a representation of the correlated traffic monitoring meta data received from the plurality of video units; and
the central controller including an archive storage configured to store a plurality of records of the composite representations of the at least one geographic map and representations of the correlated traffic monitoring meta data, each of the plurality of records corresponding to the at least one thoroughfare being monitored under mutually different event conditions.

Abstract
A distributed system for traffic monitoring and event detection includes a plurality of video units within viewing distance of a thoroughfare to be monitored. Each video unit processes a video stream while monitoring events at the thoroughfare, identifies and analyzes events, encodes traffic meta data characterizing the analysis, and transmits the meta data to a central controller. The central controller stores a geographic map representing the thoroughfare, correlates the meta data received from the video units, and forms a composite representation of the geographic map and the correlated meta data. The central controller replays previously stored composite representations of the geographic map and the correlated meta data, which were monitored under mutually different event conditions. The central controller is also configured to allow changes to previously stored composite representations of the geographic map and to the correlated meta data for the purpose of understanding the impact of change.
