What is meant by "initial green time" in the context of traffic signals?

Initial green time refers to the minimum duration that the green indication must be displayed to effectively manage traffic flow at an intersection. This time allocation is crucial as it ensures that vehicles have sufficient opportunity to enter and clear the intersection safely before the signal changes. Properly setting the initial green time can help in reducing delays, improving traffic efficiency, and minimizing the risk of congestion. It's also important for accommodating various traffic volumes and types, as well as allowing for safe pedestrian crossings where applicable. In essence, this foundational timing assists in maintaining a balanced and safe traffic signal operation.
