What is the default speed for a walking pedestrian in feet per second?

• A. 2.5 ft/s
• B. 3.0 ft/s
• C. 3.5 ft/s
• D. 4.0 ft/s

Answer: (C)

The default speed for a walking pedestrian is typically established at 4.0 feet per second. This value is widely accepted in transportation engineering and is often used in the design of pedestrian facilities, such as sidewalks and crosswalks. The basis for this default speed reflects the average walking pace of a person maneuvering through urban environments.

Various standards and guidelines inform these values, taking into account factors such as safety, comfort, and efficiency in pedestrian movement. When designing infrastructure, using this standard speed helps engineers ensure that pedestrian traffic flows smoothly and safely. It also aids in assessing the timing of traffic signals, spacing of crosswalks, and overall pedestrian experience.

This context emphasizes the importance of adhering to established norms in pedestrian movement studies, ensuring that planning efforts cater effectively to foot traffic in urban design and transportation projects.
