What impact does an effective green time have on traffic flow?

• A. Increases average wait time for vehicles
• B. Reduces the throughput of vehicles at intersections
• C. Enhances the capacity of the intersection
• D. Decreases overall signal timing efficiency

Answer: (C)

An effective green time is integral to the functionality of traffic signals, as it directly influences how vehicles navigate through intersections. When green time is optimized, it allows more vehicles to clear the intersection during the green phase. This enhancement in green time can be particularly beneficial during peak traffic periods, as it increases the number of vehicles that can safely cross the intersection. By improving the capacity of the intersection, which refers to the maximum number of vehicles that can pass through it in a given time frame, optimal green time reduces congestion and facilitates smoother traffic flow. This can lead to shorter delays for drivers and a more efficient transportation network overall. An effective green time strategy ensures that the green signal is long enough to accommodate the traffic volumes, thus enhancing intersection performance. While other options emphasize negative outcomes like increased wait times or reduced throughput, these would not occur under conditions of effective green time. Instead, such optimized timing focuses on minimizing delays and allowing for a greater volume of traffic to move seamlessly through the intersection, demonstrating its positive impact on traffic flow.
