Project Functional Requirements (Element - Functional Object):

• City of Orlando Field Equipment - Roadway Signal Control
• 1: The field element shall control traffic signals under center control.
• 10: The field element shall receive request for transit vehicle signal priority.


• City of Orlando 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.


• FDOT District 5 Field Equipment - Roadway Signal Control
• 1: The field element shall control traffic signals under center control.
• 10: The field element shall receive request for transit vehicle signal priority.


• FDOT District 5 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.


• LYNX Transit Vehicles - Transit Vehicle Signal Priority
• 1: The transit vehicle shall determine the schedule deviation and estimated times of arrival (ETA) at transit stops.
• 2: The transit vehicle shall send priority requests to traffic signal controllers at intersections, pedestrian crossings, and multimodal crossings on the roads (surface streets) and freeway (ramp controls) network that enable a transit vehicle schedule deviation to be corrected.


• Orange County Field Equipment - Roadway Signal Control
• 1: The field element shall control traffic signals under center control.
• 10: The field element shall receive request for transit vehicle signal priority.


• Orange 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.
