Systems and methods for policy centric data retention in traffic monitoring

Abstract

A traffic monitoring system includes a roadside traffic sensor unit and an off-site device remote from the traffic sensor unit. The roadside traffic sensor unit includes an imaging device that captures images of vehicles within a field-of-view of the imaging device, an image processing unit that generates a recognition record from the captured images of a vehicle, and a transceiver that transmits the recognition record. The off-site device includes a transceiver that receives the recognition record and a hot list identifying one or more vehicles-of-interest, a memory that stores the received recognition record for up to a retention period, and a processor that sets the retention period based on a comparison of the recognition record to the hot list identified vehicles-of-interest. The retention period can be variably set according to the severity of any “hits” to the hot list.
