Project Functional Requirements (Element - Functional Object):

County Fire EMS/Rescue Vehicles - EV On-Board En Route Support

1: The emergency vehicle, including roadway service patrols, shall track its current location.
5: The emergency vehicle shall send requests to traffic signal control equipment at the roadside to preempt the signal.

Manatee County Field Equipment - Roadway Signal Control

1: The field element shall control traffic signals under center control.
15: The field element shall receive requests for emergency vehicle signal preemption.
5: The field element shall report current preemption status to the center.

Manatee County Field Equipment - Roadway Signal Preemption

2: The field element shall inform the controlling center when preemption requests have been received.

Manatee County Field Equipment - RSE Intersection Management

Manatee County TMC - TMC Signal Control

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.
14: The center shall support requests from emergency management centers to provide responding emergency vehicles with signal preemption.

Manatee-Sarasota Regional Traffic Management Center - Emergency Routing

9: The center shall provide the capability to request special traffic control measures, such as signal preemption, from the traffic management center to facilitate emergency vehicle progress along the suggested route.

Manatee-Sarasota Regional Traffic Management Center - TMC Signal Control

1: The center shall remotely control traffic signal controllers.
4: The center shall collect traffic signal controller fault data from the field.
8: The center shall maintain traffic signal coordination including synchronizing clocks throughout the system.
