1.3.1.3: Process Traffic Images

This process shall process raw traffic image data received from devices located on the road (surface street) and freeway network served by the Manage Traffic function. The process shall transform the raw data into images that can be sent to another process for incident or work zone intrusion detection. It shall also act as the control interface through which the images of traffic conditions can be changed by the traffic operations personnel and maintenance and construction center personnel, who shall also be supplied with images for viewing. This process shall also provide operational status (state of the device, configuration, and fault data) to other processes in the Manage Traffic and Manage Maintenance and Construction functions that are monitoring the health of field equipment so that repairs can be scheduled by those other processes if deemed necessary.
