name	type	description	constraints
timing_phase_id	any	Primary key.	{'required': True}
timing_plan_id	any	Foreign key; connects to a timing_plan associated with a controller.
signal_phase_num	integer	Signal phase number. Typically the NEMA phase number.	{'minimum': 0, 'required': True}
min_green	number	The minimum green time in seconds for an actuated signal. Green time in seconds for a fixed time signal.	{'minimum': 0}
max_green	number	Optional.The maximum green time in seconds for an actuated signal; the default is minimum green plus one extension	{'minimum': 0}
extension	number	Optional. The number of seconds the green time is extended each time vehicles are detected.	{'minimum': 0, 'maximum': 120}
clearance	number	Yellow interval plus all red interval	{'minimum': 0, 'maximum': 120}
walk_time	number	If a pedestrian phase exists, the walk time in seconds	{'minimum': 0, 'maximum': 120}
ped_clearance	number	If a pedestrian phase exists, the flashing don't walk time.	{'minimum': 0, 'maximum': 120}
ring	integer	Required. Phases that may operate sequentially. With dual rings, two non-conflicting phases may operate at the same time	{'required': True, 'minimum': 0, 'maximum': 12}
barrier	integer	Required. Set of phases in both rings that must end at the same time	{'required': True, 'minimum': 0, 'maximum': 12}
position	integer	Required. Position.	{'required': True}
