• City of Lakeland 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.
• 8: The field element shall report current transit priority status to the center.


• Lakeland Citrus Connection Transit Dispatch - Transit Center Priority Management
• 1: The center shall analyze transit vehicle schedule performance to determine the need for priority along certain routes or at certain intersections.
