What is the maximum capacity of a sidewalk in pedestrians per minute per foot?

• A. 20 p/min/ft
• B. 23 p/min/ft
• C. 25 p/min/ft
• D. 30 p/min/ft

Answer: (B)

The maximum capacity of a sidewalk is typically assessed based on pedestrian flow rates, which are influenced by various factors such as the width of the sidewalk, the presence of obstacles, and the behavior of pedestrians. In urban planning and transportation engineering, a commonly accepted figure for maximum pedestrian flow rate is approximately 23 pedestrians per minute per foot of sidewalk width. This figure reflects a situation where the sidewalk is unobstructed and pedestrians are moving at a comfortable pace.

This value is derived from extensive studies on pedestrian movement and is characterized by normal walking conditions in urban environments. It allows for safe passage and minimizes crowding, which is crucial for maintaining the safety and comfort of pedestrians.

Values above this range could lead to congestion and difficulties in movement, while values below it might not utilize the sidewalk's capacity efficiently. Thus, the choice reflecting the maximum capacity resonates well with empirical research and practical applications in transportation design.
