Project Functional Requirements (Element - Functional Object):

• City of Fort Pierce Engineering Department Traffic Control - TMC Regional Traffic Management
• 1: The center shall exchange traffic information with other traffic management centers including incident information, congestion data, traffic data, signal timing plans, and real-time signal control information.
• 2: The center shall exchange traffic control information with other traffic management centers to support remote monitoring and control of traffic management devices (e.g. signs, sensors, signals, cameras, etc.).


• City of Port St. Lucie Traffic Operations - TMC Regional Traffic Management
• 1: The center shall exchange traffic information with other traffic management centers including incident information, congestion data, traffic data, signal timing plans, and real-time signal control information.
• 2: The center shall exchange traffic control information with other traffic management centers to support remote monitoring and control of traffic management devices (e.g. signs, sensors, signals, cameras, etc.).


• St. Lucie County 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.


• St. Lucie County TMC - 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.
• 3: The center shall monitor, analyze, and store multimodal crossing, high occupancy vehicle (HOV) and high occupancy toll (HOT) lane sensor data under remote control of the center.
• 4: The center shall distribute road network conditions data (raw or processed) based on collected and analyzed traffic sensor and surveillance data to other centers.
• 5: The center shall respond to control data from center personnel regarding sensor and surveillance data collection, analysis, storage, and distribution.
• 6: The center shall maintain a database of surveillance equipment and sensors and associated data (including the roadway on which they are located, the type of data collected, and the ownership of each).
• 7: The center shall remotely control devices to detect traffic.


• St. Lucie County TMC - TMC Regional Traffic Management
• 1: The center shall exchange traffic information with other traffic management centers including incident information, congestion data, traffic data, signal timing plans, and real-time signal control information.
• 2: The center shall exchange traffic control information with other traffic management centers to support remote monitoring and control of traffic management devices (e.g. signs, sensors, signals, cameras, etc.).
