Which components are included in a traffic signal phase split?

The correct answer includes green time, yellow time, and red time as critical components of a traffic signal phase split.

In a traffic signal operation, each phase is defined by these three elements. Green time refers to the duration when the traffic signal is green, allowing vehicles or pedestrians to proceed through the intersection. Yellow time serves as a warning signal indicating that the light is about to change from green to red, allowing drivers to make safe decisions to either clear the intersection or prepare to stop. Red time is the period during which the signal is red and traffic is required to stop for safety.

Understanding these components is essential for traffic signal technicians because they directly relate to flow management and safety at intersections. The correct allocation of each type of time ensures that traffic operates smoothly while minimizing the risk of accidents. Recognizing the significance of these elements can help in designing efficient traffic signal plans and troubleshooting issues related to signal operation.
