Interfaces:

Roadway Basic Surveillance

• The field element shall collect, process, and send traffic images to the center for further analysis and distribution.
• The field element shall return CCTV system operational status to the controlling center.
• The field element shall return CCTV system fault data to the controlling center for repair.
• The field element shall return sensor system operational status to the controlling center.
• The field element shall return sensor and fault data to the controlling center for repair.

Roadway Equipment Coordination

• The field element shall include sensors (such as traffic, environmental, and work zone intrusion detection sensors) that provide data and status information to other field element devices (such as dynamic message signs, ramp meters, traffic signals, work zone intrusion alert systems), without center control.
• The field element shall include sensors (such as traffic, environmental, and work zone intrusion detection sensors) that receive control information from other field element devices, without center control.
• The field element shall include devices (such as arterial or freeway controllers, roadway automated treatment systems, barrier and safeguard systems, emissions or pollution systems, and work zone intrusion alert systems) that provide data and status information to other field element devices (such as dynamic message signs, traffic controllers on adjacent intersections), without center control.
• The field element shall include devices (such as arterial or freeway controllers, roadway automated treatment systems, barrier and safeguard systems, emissions or pollution systems, and work zone intrusion alert systems) that receive control information from other field element devices, without center control.

Roadway Work Zone Traffic Control

• The field element shall collect, process, and send work zone images to the center for further analysis and distribution, under center control.
• The field element shall provide operational status for the surveillance (e.g. CCTV), driver information systems, and gates/barriers in work zones to the maintenance center.
