What is an important feature of escalator design for passenger safety?

The importance of anti-slip surfaces on escalator steps lies in their crucial role in enhancing passenger safety. These surfaces are specifically designed to provide traction, significantly reducing the risk of slips and falls, which can lead to injuries. On escalators, where passengers are often moving quickly and may not always be paying full attention, a secure footing is vital for maintaining balance and ensuring safe transit.

While colorful lights may enhance the visual appeal of an escalator, they do not contribute to safety. High-speed operation might increase efficiency but can pose safety risks, especially for those who are not able to board or exit quickly. Automated announcements can improve awareness of safety practices but do not directly prevent accidents like anti-slip surfaces do. Thus, the incorporation of anti-slip materials is a fundamental aspect of escalator design focused on safeguarding passengers.
