Project Functional Requirements (Element - Functional Object):

County and Local Field Equipment - Roadway Signal Control

1: The field element shall control traffic signals under center control.
13: The field element shall provide to roadside equipment the intersection geometry and signal phase movement information including phase and timing information, alarm status, and priority/preempt status.
2: The field element shall respond to pedestrian crossing requests by accommodating the pedestrian crossing.
3: The field element shall provide the capability to notify the traffic management center of pedestrian calls and pedestrian accommodations.
4: The field element shall report the current signal control information to the center.
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.
9: The field element shall report current intersection signal timing information to roadside equipment for transmission to connected vehicles.

Palm Beach 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.

Palm Beach County 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.
3: The field element shall provide the capability to notify the traffic management center of pedestrian calls and pedestrian accommodations.
4: The field element shall report the current signal control information to the center.
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.

Palm Beach 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.
7: The center shall remotely control devices to detect traffic.

Palm Beach County TMC - 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.

Palm Beach County TMC - TMC Signal Control

1: The center shall remotely control traffic signal controllers.
10: The center shall adjust signal timing in respond to a signal prioritization, signal preemption, pedestrian call, multi-modal crossing activation, or other requests for right-of-way.
17: The center shall remotely control devices to detect traffic in the vicinity of traffic signals.
2: The center shall accept notifications of pedestrian calls.
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.
5: The center shall manage (define, store and modify) control plans to coordinate signalized intersections, to be engaged at the direction of center personnel or according to a daily schedule.
6: The center shall implement control plans to coordinate signalized intersections based on data from sensors.
7: The center shall manage boundaries of the control sections used within the signal system.
8: The center shall maintain traffic signal coordination including synchronizing clocks throughout the system.
9: The center shall implement control plans to coordinate signalized intersections based on data from sensors and connected vehicles.
