What additional factors need to be considered when establishing minimum green time?

When establishing minimum green time for traffic signals, it is crucial to consider pedestrian timing. This factor is important because it ensures sufficient time for pedestrians to safely cross the intersection. The minimum green time must accommodate not only the vehicular traffic but also the time needed for pedestrians to complete their crossing, especially in busy or high-traffic areas.

Pedestrian crossing times are influenced by various elements such as the standard walking speed, the length of the crosswalk, and the needs of vulnerable populations, such as the elderly or those with disabilities. In addition, local regulations or guidelines often dictate the timing considerations for pedestrian signals to enhance safety and promote efficient traffic flow.

In contrast, while traffic speed, pavement conditions, and weather conditions can impact overall traffic dynamics, they do not directly dictate the necessary green time for accommodating pedestrian crossings as effectively as the timing considerations specific to pedestrian movement. Therefore, pedestrian timing stands out as a critical factor in the determination of minimum green time at traffic signals.
