Project Functional Requirements (Element - Functional Object):

• City of Fort Pierce Engineering Department Traffic Control - 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.


• City of Fort Pierce Engineering Department Traffic Control - TMC Roadway Equipment Monitoring
• 1: The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) operational status.
• 2: The center shall collect and store CCTV surveillance system (traffic, pedestrian) operational status.
• 3: The center shall collect and store sensor (traffic, pedestrian, multimodal crossing) fault data and send to the maintenance center for repair.


• City of Fort Pierce Engineering Department Traffic Control - TMC Signal Control
• 1: The center shall remotely control traffic signal controllers.
• 12: The center shall adjust signal timing in respond to traffic and environmental parameters at each intersection in real time and adapts so that the traffic network is optimized using available green time to serve the actual traffic demands while minimizing the environmental impact.
• 14: The center shall support requests from emergency management centers to provide responding emergency vehicles with signal preemption.
• 15: The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements at or near signalized intersections.
• 17: The center shall remotely control devices to detect traffic in the vicinity of traffic signals.
• 3: The center shall collect traffic signal controller operational status and compare against the control information sent by the center.
• 4: The center shall collect traffic signal controller fault data from the field.


• City of Fort Pierce 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.
• 4: The field element shall return sensor and CCTV system operational status to the controlling center.
• 5: The field element shall return sensor and CCTV system fault data to the controlling center for repair.


• City of Fort Pierce Field Equipment - Roadway Field Management Station Operation
• 1: The field element shall accept configuration information from the center.
• 2: The field element shall pass data provided by the center to local field devices and report data from the field devices back to the center.


• City of Fort Pierce Field Equipment - Roadway Signal Control
• 1: The field element shall control traffic signals under center control.
• 2: The field element shall respond to pedestrian crossing requests by accommodating the pedestrian crossing.
• 6: The field element shall return traffic signal controller operational status to the center.
• 7: The field element shall return traffic signal controller fault data to the center.
