	'''Support. '''The features of traffic control signals of interest to road users are the location, design, and meaning of the signal indications. Uniformity in the design features that affect the traffic to be controlled, as set forth in this Manual, is especially important for the safety and efficiency of operations.

	Traffic control signals can be operated in pretimed, semi-actuated, or full-actuated modes. For isolated (non-interconnected) signalized locations on rural high-speed highways, full-actuated mode with advance vehicle detection on the high-speed approaches is typically used. These features are designed to reduce the frequency with which the onset of the yellow change interval is displayed when high-speed approaching vehicles are in the “dilemma zone” such that the drivers of these high-speed vehicles find it difficult to decide whether to stop or proceed.

	~~[[902.23 Traffic Signal Phasing and Operation#902.23.1_Traffic_Signal_Operation\|EPG 902.23.1]] contains information regarding traffic control signal operation.~~

	~~'''Standard. '''The design and operation of traffic control signals shall take into consideration the needs of all modes of traffic including access and safety.~~

	When a traffic control signal is not in operation, such as before it is placed in service, during seasonal shutdowns, or when it is not desirable to operate the traffic control signal, the signal heads shall be covered, turned, or taken down to clearly indicate that the traffic control signal is not in operation.

	If a traffic control signal head is not in operation and has a yellow retroreflective strip along the perimeter of its signal backplate (see the fifth option paragraph of [[902.4_Design_Features_of_Traffic_Control_Signals_(MUTCD_Chapter_4D)#902.4.6_Visibility,_Aiming,_and_Shielding_of_Signal_Faces_(MUTCD_Section_4D.06)\|EPG 902.4.6]]), the signal head, shall be covered. If a cover is placed over a traffic control signal head that is not in operation, the entire signal head, including the signal faces and backplate shall be covered.

	~~'''Standard. '''A traffic control signal shall control traffic only at the intersection or midblock location where the signal faces are placed.~~

	'''Guidance. '''Midblock crosswalks should not be signalized if they are located within 1,000 feet from the nearest traffic control signal, unless supported by an engineering study or engineering judgment that indicates safe and efficient operation of the closely-spaced traffic control signals can be achieved.

	Midblock crosswalks should not be signalized if they are located within 100 feet from side streets or driveways that are controlled by STOP signs or YIELD signs, unless supported by an engineering study or engineering judgment that considers restricting turning movements from the side street or driveway to eliminate conflicts with pedestrian and bicyclist movements.

	Engineering judgment should be used to determine the proper phasing and timing for a traffic control signal. Since traffic flows and patterns change, phasing and timing should be reevaluated regularly and updated if needed.

	Traffic control signals within ½ mile of one another along a major route or in a network of intersecting major routes should be coordinated, preferably with interconnected controller units. Where traffic control signals that are within ½ mile of one another along a major route have a jurisdictional boundary or a boundary between different signal systems between them, coordination across the boundary should be considered.

	~~'''Support. '''Signal coordination need not be maintained between control sections that operate on different cycle lengths.~~

	[[902.6 Steady (Stop-and-Go) Operation of Traffic Control Signals (MUTCD Chapter 4F) #902.6.19\|EPG 902.6.19]] and [[913.4 Flashing-Light Signals, Automatic Gates, and Traffic Control Signals (MUTCD Chapter 8D) #913.4.9\|EPG 913.4.9]] contain information about coordination of traffic control signals with grade crossing signals.
