What is RBC?
What features?
Why RBC? - the features that were asked for most with NEMA (more rings & barriers) would have required a completer rewrite of the controller logic

Detector Options
Call Phases / Extend Phases
Delay / Extend / Carry Over Timing
Added Initial / Maximum Initial
Reduce After / Time to Reduce
Added Initial Mode If Enabled, this detector will count the number of actuations received when ALL Call signal groups are yellow or red. When the next Call signal group changes to green, a variable initial interval will time based on the total number of actuations on all detectors enabled for the Added Initial Mode and the Added initial time defined for the signal group. The actuation count will then be reset to zero.
Delay The amount of time a detector input must have continuous presence before placing a call to the Call signal groups.
Extend The amount of time that Extend SGs will be extended after the detector input is off. See Detector Mode for alternate uses of the Extend time for different modes.
Carry Over When the Detector Mode is Disconnect, this is the amount of time allowed between vehicle actuations during the Extend signal group green interval before the detector will be disconnected for the remainder of the green interval and cease to extend the signal group.

Call Modes

Relative priority
No Call SGs Normally when there is a call for a transit priority, all Parent SGs will be called since the transit priority must time with its Parent SGs. Any signal groups flagged for this parameter will not be called when the associated transit priority has a call.
Priority SGs These are the signal groups that the controller will choose as the priority movements that will serve concurrently with the Transit SG. If this parameter is left undefined, the controller will choose the Parent SGs as the priority movements.

Start timing – when preempt first goes active, this is the time that the controller will allow sg’s and overlaps to remain green, in walk, in ped clr.
Zero timing – during an active preempt, sg’s can be terminated immediately out of green, walk, ped clr.
