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.
