What is indicated by the maximum green time in a traffic signal operation?

The maximum green time in a traffic signal operation is defined as the longest duration for which a green signal can be displayed. This parameter is crucial for traffic signal management as it ensures that vehicles can pass safely and efficiently through an intersection during the green phase. Setting this time helps traffic engineers manage traffic flow, prevent congestion, and ensure that the system operates within safe operational limits.

In practical terms, if the green time is too short, vehicles may not clear the intersection before the signal changes, leading to increased delay and potential traffic violations. Conversely, if the maximum green time is too long, it may lead to unnecessary waiting for cross traffic and pedestrians. Thus, determining the appropriate maximum green time is critical for balancing efficiency and safety within the overall traffic signal operation.
