In addition to traditional manned elevators, there are now some automated elevators such as escalators and moving walkways. These devices are typically used in commercial venues and public transportation systems to quickly and efficiently transport large numbers of people. 

In some high-rise buildings, there are also high-speed elevators that can quickly transport people and items in a short period of time. These elevators typically have higher speeds and more advanced control systems to ensure their safety and reliability. 

The development of elevators is increasingly emphasizing environmental protection and energy conservation. Some elevators adopt advanced technologies and materials, such as energy recovery systems, LED lighting, high-efficiency motors, etc., to reduce energy consumption and environmental impact. 

Overall, elevators are an indispensable part of modern society, providing people with convenient, safe, and efficient transportation services, and constantly developing and innovating to meet the needs of different places and uses.
