For example, the vehicular green interval is the period of time that vehicular traffic has a green signal. The interval is fixed in pre-timed control and varied in actuated control. In actuated settings, the minimum interval in the minimum amount of time for which a signal will stay green before changing.
Traffic lights control flows of traffic using social norms and legal rules. In most jurisdictions, it is against the law to disobey traffic signals and the police, or devices such as red light cameras, can issue fines or other penalties – and in some cases prosecute – drivers who break those laws.

Signal timing is the technique which traffic engineers use to distribute right-of-way at a signalized intersection. The process includes selecting appropriate values for timing, which are implemented in specialized traffic signal controllers.
Are Sacramento’s traffic lights controlled by sensors or cameras? Here’s what the city told us.
Traffic signal preemption (also called traffic signal prioritisation) is a system that allows an operator to override the normal operation of traffic lights.The most common use of these systems manipulates traffic signals in the path of an emergency vehicle, halting conflicting traffic and allowing the emergency vehicle right-of-way, thereby reducing response times and enhancing traffic safety.
Traffic lights – devices positioned at road intersections, pedestrian crossings and other locations – control flows of traffic with social norms and laws created by the state. [1] Traffic signals have to convey messages to drivers in a short period of time about constantly-changing road rules. [2]
Split Cycle Offset Optimisation Technique (SCOOT) is a real time adaptive traffic control system for the coordination and control of traffic signals across an urban road network. Originally developed by the Transport Research Laboratory [ 1 ] for the Department of Transport in 1979, research and development of SCOOT has continued to present day.
An example of center to center communications is two traffic management centers that exchange real-time information about the inventory and status of traffic control devices. This allows each center system to know what timing plan, for example, the other center system is running to allow traffic signal coordination across center geographic ...
