What is the primary purpose of signal cycles in traffic management?

The primary purpose of signal cycles in traffic management is to regulate traffic flow. Signal cycles are designed to create a sequence of green, yellow, and red signals that control the right-of-way at intersections. By alternating traffic movements and allowing vehicles and pedestrians to safely pass through intersections, signal cycles help to manage the flow of traffic efficiently.

Effective traffic regulation through signal cycles can minimize congestion, improve safety by reducing the likelihood of collisions, and enhance the overall efficiency of the transportation system. By providing clear signals to drivers and pedestrians, these cycles ensure that traffic moves in an orderly manner, thus optimizing the use of road space and improving travel times. This focus on regulating traffic flow is crucial in urban environments where multiple road users interact frequently.
