What is the purpose of escalator handrails?

The primary purpose of escalator handrails is to provide support and safety to passengers. Handrails are designed to help individuals maintain their balance while using the escalator, especially when transitioning onto or off of the moving steps. This is particularly important in maintaining safety, as escalators can pose a risk of slips or falls if a passenger is unsteady. The handrails often move in sync with the escalator steps, ensuring that riders have a secure grip as they ascend or descend.

While the enhancements in design, operational efficiency, and indication of travel direction are all aspects related to escalators, they do not capture the essential function of handrails directly tied to passenger safety and stability. This makes the option highlighting support and safety the most relevant and accurate.
