Project Functional Requirements (Element - Functional Object):

• FDOT District 1 Field 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.


• FDOT District 1 Field Equipment - Roadway Traffic Information Dissemination
• 1: The field element shall include dynamic message signs for dissemination of traffic and other information to drivers, under center control; the DMS may be either those that display variable text messages, or those that have fixed format display(s) (e.g. vehicle restrictions, or lane open/close).
• 4: The field element shall provide fault data for the driver information systems equipment (DMS, HAR, etc.) to the center for repair.
• 7: The field element shall include devices that receive configuration data from other field element devices, without center control.


• FDOT District 1 Field Equipment - Roadway Traffic Metering
• 1: The field element shall regulate the flow of traffic on ramps, interchanges, and the mainline, under center control.
• 2: The field element shall monitor operation of ramp, interchange, and mainline meters and report to the center any conflicts between received control plans and current system operation.
• 3: The field element shall return ramp, interchange, and mainline meter operational status to the controlling center.


• FDOT I-75 Satellite Center - 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.


• FDOT I-75 Satellite Center - TMC Roadway Equipment Monitoring
• 1: The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) operational status.


• FDOT I-75 Satellite Center - TMC Traffic Information Dissemination
• 1: The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers.
• 15: The center shall coordinate information dissemination with other traffic management centers.
• 3: The center shall collect operational status for the driver information systems equipment (DMS, HAR, etc.).
• 4: The center shall collect fault data for the driver information systems equipment (DMS, HAR, etc.) for repair.


• FDOT I-75 Satellite Center - TMC Traffic Metering
• 1: The center shall remotely control systems to manage use of the freeways, including ramp, interchange, and mainline metering.
• 2: The center shall collect operational status from ramp meters, interchange meters, and mainline meters and compare against the control information sent by the center.
• 3: The center shall collect fault data from ramp meters, interchange meters, and mainline meters.


• FDOT SWIFT Center - 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.


• FDOT SWIFT Center - TMC Roadway Equipment Monitoring
• 1: The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) operational status.


• FDOT SWIFT Center - TMC Traffic Information Dissemination
• 1: The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers.
• 15: The center shall coordinate information dissemination with other traffic management centers.
• 18: The center shall distribute wrong way entry data to emergency management centers and traveler information providers.
• 4: The center shall collect fault data for the driver information systems equipment (DMS, HAR, etc.) for repair.


• FDOT SWIFT Center - TMC Traffic Metering
• 1: The center shall remotely control systems to manage use of the freeways, including ramp, interchange, and mainline metering.
• 2: The center shall collect operational status from ramp meters, interchange meters, and mainline meters and compare against the control information sent by the center.
• 3: The center shall collect fault data from ramp meters, interchange meters, and mainline meters.

Project Operational Concepts:

Roles and Responsibilities

• FDOT District 1
• Monitor traffic images and traffic flow data through CCTVs and field sensors, and maintain operational control of its own field equipment.
• Operate and coordinate traffic control devices, traffic sensors, and CCTVs on FDOT freeways, including the ability to control traffic on overflow ramps.
• Owns, operations and maintains DMS.
