Project Functional Requirements (Element - Functional Object):

Suburban Municipality Street Department Operations/Dispatch - TMC Basic Surveillance

1: The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements under remote control of the center.
2: The center shall monitor, analyze, and distribute traffic images from CCTV systems under remote control of the center.
7: The center shall remotely control devices to detect traffic.

Suburban Municipality Street Department Operations/Dispatch - TMC Passive Surveillance

1: The center shall collect time stamped vehicle identities from field equipment.
2: The center shall correlate the time stamped vehicle identities in order to calculate link travel times and derive other traffic measures.

Suburban Municipality Street Department Roadside Equipment - Roadway Basic Surveillance

1: The field element shall collect, process, digitize, and send traffic sensor data (speed, volume, and occupancy) to the center for further analysis and storage, under center control.
2: The field element shall collect, process, and send traffic images to the center for further analysis and distribution.
4: The field element shall return sensor and CCTV system operational status to the controlling center.

Suburban Municipality Street Department Roadside Equipment - Roadway Passive Monitoring

1: The field element shall collect, process, and send data to the center to uniquely identify passing vehicles in order to support travel time measurement
