Minimum green time for pedestrian signals is influenced by what factor?

• A. Traffic volume
• B. Crosswalk width
• C. Time of day
• D. Roadway speed limit

Answer: (B)

The minimum green time for pedestrian signals is directly influenced by crosswalk width. This factor is critical because wider crosswalks require more time for pedestrians to safely traverse the intersection. If the crosswalk width increases, it is essential to provide a longer duration of the green signal to ensure that pedestrians have enough time to walk across safely without feeling rushed. In contrast, factors such as traffic volume or roadway speed limit may influence the overall traffic signal timing but do not specifically dictate the minimum green time required for pedestrians. The time of day might affect traffic patterns but does not directly account for the physical dimensions of the crosswalk itself, which is a primary concern when determining how much time pedestrians need for safe passage. Focusing on crosswalk width allows engineers and planners to design pedestrian signals that are responsive to the actual conditions faced by users in that area.
