When unable to maintain a minimum width of 60 inches in a pedestrian pathway, what size passing space should be provided?

The correct answer emphasizes the importance of providing adequate space for pedestrians to safely pass through areas where maintaining a minimum width of 60 inches is not possible. When such a width cannot be provided, it is essential to create a defined passing space that allows individuals to navigate around obstacles comfortably and safely.

A 60" x 60" passing space ensures that there is enough room for two pedestrians to pass each other without having to navigate around each other in a constrained area. This design considers the typical width of individuals and allows for necessary clearance, especially for those who may be using mobility aids or assistance devices.

The remaining choices do not meet the spatial requirements sufficiently for safe pedestrian movement. For example, a smaller passing space, such as 48" x 48", may feel restrictive and uncomfortable for users, while 60" x 30" does not provide enough width for comfortable passing and could lead to congestion in that area. Similarly, while a 72" x 72" space may offer extra room, it may be overly large and not practical in all situations. Therefore, providing a 60" x 60" passing space strikes a balance between functionality and the constraints of the pedestrian pathway.
