What is the minimum clear height required above an arcaded sidewalk?

The minimum clear height required above an arcaded sidewalk is established to ensure safety and accessibility for pedestrians. A height of 3 meters allows for ample clearance for individuals walking underneath the arcade, which often includes various types of users, such as those using wheelchairs or carrying tall objects. This standard takes into consideration not only the average height of pedestrians but also the need for an unobstructed pathway to avoid injury and ensure comfort.

Establishing a minimum height of 3 meters also helps accommodate additional factors, such as weather conditions that may require pedestrians to carry umbrellas or for people to maneuver through without the risk of bumping heads. This height reflects best practices and regulations, aimed at promoting pedestrian safety and usability in urban environments.

In contrast, the other specified heights may be insufficient for various user needs and could lead to increased incidents of accidents or discomfort for pedestrians, thus failing to uphold public safety standards.
