– Calhoun County
– Franklin County
– Gadsden County
– Gulf County
– Holmes County
– Jackson County
– Liberty County
– Wakulla County
– Washington County

Project Functional Requirements (Element - Functional Object):

• County and Local Field Equipment - Roadway Signal Control
• 5: The field element shall report current preemption status 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.


• FDOT District 3 Chipley RTMC - 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.


• FDOT District 3 Chipley RTMC - 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.
• 15: The center shall monitor, analyze, and store traffic sensor data (speed, volume, occupancy) collected from field elements at or near signalized intersections.
• 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.

Standards:
