Automated People Mover Standards establishes the minimum set of requirements necessary to achieve an acceptable level of safety and performance for an automated people mover (APM) system. An APM is defined as a guided transit mode with fully automated operation, featuring vehicles that operate on guideways with exclusive right-of-way. This standard, which is divided into three parts, includes minimum requirements for the design, construction, operation, and maintenance of APM systems.

Part 1 provides general information and definitions followed by discussions of the operating environment, safety requirements, system dependability, automatic train control subsystems, and audio and visual communications.
