(3)

“Bus priority system” is a traffic control signal system that includes a traffic control signal operating device and signal preemption device designated to provide buses the capability to modify the green intervals but not the display sequence of a traffic control signal. The system can be implemented for an intersection, an arterial corridor or a defined geographic area.

(4)

“Emergency preemption system” is a traffic control signal system that includes a traffic control signal operating device and signal preemption device for the purpose of providing emergency vehicles the capability to modify the green intervals of a traffic control signal or change the display sequence.

(8)

“Traffic control signal” means a type of highway traffic signal by which traffic is alternately directed to stop and permitted to proceed.
