Project Functional Requirements (Element - Functional Object):

• City of Gainesville Field Equipment - Roadway Signal Control
• 1: The field element shall control traffic signals under center control.
• 4: The field element shall report the current signal control information to the center.
• 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.
• 8: The field element shall report current transit priority status to the center.


• Gainesville Smart Traffic TMC - TMC Signal Control
• 1: The center shall remotely control traffic signal controllers.
• 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.

Project Operational Concepts:

Roles and Responsibilities

• Gainesville Traffic Operations Division
• Coordinate emergency traffic signal control with the county EOC/Warning Point.
• Coordinate traffic information with FDOT District 2.
• Obtain traffic images and traffic flow data using CCTVs and field sensors, and maintain operational control of its own field equipment.
• Operate traffic signal systems for the City of Gainesville and Alachua County.
• Provide emergency signal preemption for county fire/EMS.
• Provide interconnection between railroad equipment and traffic signal systems to update signal timing when HRIs are blocked by trains.
• Provide transit signal priority using roadside devices for Gainesville transportation service vehicles.
