What are vertical and horizontal systems such as elevators and shuttles collectively referred to as?

The term that best encompasses vertical and horizontal systems, such as elevators and shuttles, is often referred to as "vertical circulation systems." These systems are specifically designed to facilitate the movement of people between different levels of a facility, such as floors in a stadium, arena, or other sporting venues. Vertical circulation systems enable attendees to access various areas efficiently, ensuring smooth traffic flow and enhancing the overall user experience in a facility.

While the other options might seem relevant in particular contexts, they do not capture the essence of what is described as vertical and horizontal circulation within the domain of facility management. "Transportation systems" generally refer to a broader classification that may not strictly include the specific design and function of elevators and shuttles. "Personal transportation systems" could imply transportation specifically for individual use rather than the collective movement of groups. "Access systems" is a more generic term and may encompass various forms of access, not solely focused on vertical and horizontal movement.

Therefore, vertical circulation systems accurately describe the role of elevators, shuttles, and similar systems in managing movement within the facility, emphasizing their primary function in enhancing accessibility and usability for all individuals.
